Volcanoes, travel plans, and history

June 13, 2010

James is home for the weekend, then back to Wisconsin on Sunday for a summer of physics beyond my current understanding.  He flew home to wish bon voyage to Kenny, who is off to Crete to learn how to teach English, and then (we hope) to find a position teaching English to non-English speakers somewhere in Europe.

I wondered:  What about that volcano erupting in Iceland?

Little worry for the trip over, this weekend.  Longer term?

So I turned to the Smithsonian to find a volcano expert, and came up with this video of  Smithsonian Geologist Liz Cottrell who explains where the eruption of Eyjafjallajökull fits in history, and maybe some — with a lesson in how to pronounce Eyjafjallajökull’s name.

So:

  1. Can teachers figure out how to use this in geography, and in world history?  (Science teachers, you’re on your own.)
  2. Life is a gamble if you live close to a volcano, and sometimes when just happen to be downwind.
  3. In the past couple of hundred years, maybe volcanoes worldwide have been unusually quiet.
  4. As to size of eruptions and the damage potential:  We ain’t seen nothin’ recently!

Washington Times felled by DDT poisoning

June 9, 2010

Washington Times‘ owner, the Unification Church, put the paper up for sale earlier this year — tired of losing north of $30 million a year on the thing.  It appears that, in a cost-cutting move, the paper has laid off all its fact checkers and most of its editors.

And anyone with a brain.

DDT use in the U.S. peaked in 1959, with 70 million pounds of the stuff used in that year.  This ad comes from about that time.

DDT use in the U.S. peaked in 1959, with 70 million pounds of the stuff used in that year. This ad for a French product containing DDT comes from about that time.

How do we know?

Our old friend Stephen Milloy complains about Time Magazine’s “50 Worst Inventions” list, including, especially the listing of DDT, as discussed earlier.  It’s wrong, and silly.  Good fact checkers, and good editors, wouldn’t let such claptrap make it into print.

Milloy packed an astounding number of whoppers in a short paragraph about DDT:

From 1943 through its banning by the EPA in 1972, DDT saved hundreds of millions of lives all over the world from a variety of vector-borne diseases. Even when Environmental Protection Agency Administrator (and closeted environmental activist) William D. Ruckelshaus banned DDT in 1972, he did so despite a finding from an EPA administrative law judge who, after seven months and 9,000 pages of testimony, ruled that DDT presented no threat of harm to humans or wildlife. Today, a million children die every year from malaria. DDT could safely make a tremendous dent in that toll.

Let us count the errors and falsehoods:

1.  DDT was used against typhus from 1943 through about 1946, and against bedbugs; it saved millions, but not hundreds of millions. Death tolls from typhus rarely rose over a million a year, if it ever did.  Bedbugs don’t kill, they just itch.  If we add in malaria after 1946, in a few years we push to four million deaths total from insect-borne diseases — but of course, that’s with DDT being used.  If we charitably claim DDT saved four million lives a year between 1943 and 1972, we get a total of 117 million lives saved.  But we know that figure is inflated a lot.

Sure, DDT helped stop some disease epidemics.  But it didn’t save “hundreds of millions of lives” in 29 years of use.  The National Academy of Sciences, in a book noting that DDT should be banned because its dangers far outweigh its long-term benefits, goofed and said DDT had saved 500 million lives from malaria, and said DDT is one of the most beneficial chemicals ever devised by humans.  500 million is the annual infection rate from malaria, with a high of nearly four million deaths, but in most years under a million deaths.  Malaria kills about one of every 500 people infected in a year.  That’s far too many deaths, but it’s not as many lives saved as Milloy claims.

NAS grossly overstated the benefits of DDT, and still called for it to be banned.

The question is, why is Milloy grossly inflating his figures?  Isn’t it good enough for DDT to be recognized as one of the most beneficial substances ever devised?

My father always warned that when advertisers start inflating their claims, they are trying to hide something nasty.

2.  Ruckelshaus didn’t ban DDT on his own — nor was he a “closeted” environmentalist. He got the job at EPA because he was an outstanding lawyer and administrator, with deep understanding of environmental issues — his environmentalism was one of his chief qualifications for the job.  (Maybe Milloy spent the ’70s in a closet, and assumes everyone else did, too?)  But EPA acted only when ordered to act by two different federal courts (Judge David Bazelon ordered an end to all use of DDT at one of the trials).  At trial, DDT had been found to be inherently dangerous and uncontrollable.  Both courts were ready to order DDT banned completely, but stayed those orders pending EPA’s regulatory hearings and action.

In fact, regulatory actions against DDT began in the 1950s; by 1970, scientific evidence was overwhelming (and it has not be contradicted:

The U.S. Department of Agriculture, the federal agency with responsibility of regulating pesticides before the formation of the U.S. Environmental Protection Agency in 1970, began regulatory actions in the late 1950s and 1960s to prohibit many of DDT’s uses because of mounting evidence of the pesticide’s declining benefits and environmental and toxicological effects. Rachel Carson’s book Silent Spring in 1962 stimulated widespread public concern over the dangers of improper pesticide use and the need for better pesticide controls.

In 1972, EPA issued a cancellation order for DDT based on adverse environmental effects of its use, such as those to wildlife, as well as DDT’s potential human health risks. Since then, studies have continued, and a causal relationship between DDT exposure and reproductive effects is suspected. Today, DDT is classified as a probable human carcinogen by U.S. and international authorities. This classification is based on animal studies in which some animals developed liver tumors.

DDT is known to be very persistent in the environment, will accumulate in fatty tissues, and can travel long distances in the upper atmosphere. Since the use of DDT was discontinued in the United States, its concentration in the environment and animals has decreased, but because of its persistence, residues of concern from historical use still remain.

3.  Judge Sweeney ruled that DDT is dangerous to humans and especially wildlife, but that DDT’s new, Rachel-Carson-friendly label would probably protect human health and the environment. EPA Administrative Law Judge Edmund Sweeney presided at the hearings in 1971.  As in the two previous federal court trials, DDT advocates had ample opportunity to make their case.  32 companies and agencies defended the use of DDT in the proceeding.  Just prior to the hearings, DDT manufacturers announced plans to relabel DDT for use only in small amounts, against disease, or in emergencies, and not in broadcast spraying ever.  This proved significant later.

Judge Sweeney did not find that DDT is harmless.  Quite to the contrary, Sweeney wrote in the findings of the hearing:

20.  DDT can have a deleterious effect on freshwater fish and estuarine organisms when directly applied to the water.

21.  DDT is used as a rodenticide. [DDT was used to kill bats in homes and office buildings; this was so effective that, coupled with accidental dosing of bats from their eating insects carrying DDT,  it actually threatened to wipe out some species of bat in the southwest U.S.]

22.  DDT can have an adverse effect on beneficial animals.

23.  DDT is concentrated in organisms and can be transferred through food chains.

DDT use in the U.S. had dropped from a 1959 high of 79 million pounds, to just 12 million pounds by 1972.  Hazards from DDT use prompted federal agencies such as the Department of Agriculture and Department of Interior to severely restrict or stop use of the stuff prior to 1963.  Seeing the writing on the wall, manufacturers tried to keep DDT on the market by labeling it very restrictively.  That would allow people to buy it legally,  and then use it illegally, but such misuse can almost never be prosecuted.

Sweeney wrote that, under the new, very restrictive label, DDT could be kept on the market.  Ruckelshaus ruled that EPA had a duty to protect the environment even from abusive, off-label use, and issued a ban on all agricultural use.

4.  More DDT today won’t significantly reduce malaria’s death toll. Milloy fails to mention that DDT use against malaria was slowed dramatically in the mid-1960s — seven years before the U.S. banned spraying cotton with it — because mosquitoes had become resistant and immune to DDT.  DDT use was not stopped because of the U.S. ban on spraying crops; DDT use was reduced because it didn’t work.

Milloy also ignores the fact that DDT is being used today.  Not all populations of mosquitoes developed immunity, yet.  DDT has a place in a carefully-managed program of “integrated vector management,” involving rotating several pesticides to ensure mosquitoes don’t evolve immunity, and spraying small amounts of the pesticide on the walls of houses where it is most effective, and ensuring that DDT especially does not get outdoors.

To the extent DDT can be used effectively, it is being used.  More DDT can only cause environmental harm, and perhaps harm to human health.

Most significantly, Milloy grossly overstates the effectiveness of DDT.  Deaths from malaria numbered nearly 3 million a year in the late 1950s; by the middle 1960s, the death rate hovered near 2 million per year.  Today, annual death rates are under a million — less than half the death rate when DDT use was at its peak.  Were DDT the panacea Milloy claims, shouldn’t the death numbers go the other way?

Milloy gets away making wild, misleading and inaccurate claims when editors don’t bother to read his stuff, and they don’t bother to ask “does this make sense?”  Nothing Milloy claims could be confirmed with a search of PubMed, the most easily accessible, authoritative data base of serious science journals dealing with health.

Obviously, Washington Times didn’t bother to check.  Were all the fact checkers let go?

Even more lunatic

Milloy also attacked the decision to get lead out of gasoline.  Ignoring all the facts and the astoundingly long history of severe health effects from lead pollution, Milloy dropped this stinking mental turd:

As to leaded gasoline, we can safely say that leaded gasoline helped provide America and the world with unprecedented freedom and fueled tremendous prosperity. We don’t use leaded gasoline in the United States anymore, but more because people simply don’t like the idea of leaded gasoline as opposed to any body of science showing that it caused anybody any harm. It’s the dose that makes the poison, and there never was enough lead in the ambient environment to threaten health.

The U.S. found that getting lead out of gasoline actually improved our national IQ.  Lead’s health effects were so pervasive, there was an almost-immediate improvement in health for the entire nation, especially children, when lead was removed.  Denying the harms of tetraethyl lead in gasoline goes past junk science, to outright falsehood.

What is Milloy’s fascination with presenting deadly poisons as “harmless?”  Why does he hate children so?

Why do publications not catch these hallucination-like errors and junk science promotions when he writes them?

Adventures in Condor land: Moonrise over Hopper Ranch

June 8, 2010

Moon over Hopper Ranch, by Amanda Holland

Moon over Hopper Ranch, by Amanda Holland

Kathryn’s cousin Amanda Holland writes from her great adventure helping to rescue the California Condor, with this photo of the Moon, behind clouds and haze, over the mountains, from Hopper Ranch.

Here’s where I feel the pangs of leaving biology behind for rhetoric, then politics and law.  Probably the best part of research in biology was the places one had to go.  The best adventures involve getting to and back from the places researchers must go to get data or samples.

And now, with electronic cameras and cards that will easily accommodate 1,000 photos, images are easy to capture.

Some of the images I wish I could get back:  Moonrise over Shiprock*; the rattlesnake who liked to hide in the equipment box at the New Mexico Agriculture Experiment Station; the field of asparagus at the Experiment Station, poking up through the desert for the first time (I wonder if they decided to grow asparagus); thunderstorms at Shiprock and over Kimberly, New Mexico; sunrise in Huntington Canyon, Utah; looking nearly into Nevada through crystal air after a summer thunderstorm near Seeley Mountain.  There are a lot more, really.

Adventures past: We remember them warmly.  Getting out in the wild, doing the hard, grunt work necessary to learn about endangered species, or save them, or just improve conservation practices, is close to godliness, and among the greatest pleasures life can offer.

More:

  • See this photo of Shiprock and Moon, probably by a photography named William Stone; this photo of Shiprock and storm, by Radeka, is good, too; at one time my job was to drive from Farmington, New Mexico, past the Shiprock everyday, to get air pollution samples.  The Shiprock rivals Mt. Timpanogos in my personal pantheon of great mountains I grew up with.

Maybe, 4th grader disproves much warming in Beeville, not entire planet?

June 7, 2010

Hmmm.  News from Beeville is tough to come by when limited to calls that tend to catch school officials before they get to their office or after they go home (early, by most standards — but it’s summer, so we cut ’em some slack).

But we can find more information on what would be an astounding, groundbreaking study by 4th grader Julisa Castillo, which has been advertised as disproving global warming.

Again from the Beeville Bee-Picayune, about five months ago:

Conclusion: ‘pretty creative’

by Scott Reese Willey
As world leaders meet in Copenhagen to draft legislation to rein in the release of greenhouse gases and stem climate change, an R.A. Hall Elementary School student is questioning the science supporting global warming.

“There is not enough evidence to prove global warming is occurring,” fourth-grader Julisa Raquel Castillo concluded in a science project she entered in the campus’ annual science fair on Tuesday.

Julisa studied temperatures in Beeville for the past 109 years to develop her conclusion.

She researched online data basis of the National Oceanic and Atmospheric Administration, or NOAA, the National Weather Service, and checked out books on climate change at the Joe Barnhart Bee County Library.

Her findings:

• temperatures rose and fell from 1900 to 1950.

• temperatures in Beeville cooled down over a 20-year period beginning in 1955 and ending in 1975.

• Since 2001, temperatures in Beeville have grown cooler year after year.

Close to 200 R.A. Hall students entered projects in this year’s science fair, said organizer Denise Salvagno, who also teaches the school’s gifted and talented students.

Fourth- and fifth-graders were required to enter projects as part of class work; however, students in grades first, second and third could enter projects if they desired.

Students in Ben Barris’ science club at A.C. Jones High School judged the projects.

“Some of these projects are pretty creative,” said Zachary Johnson, a senior at A.C. Jones and one of the judges. “You can tell a lot of the students put a lot of effort into their projects. Some of them didn’t put much effort into it but a lot of them did and, overall, I’m impressed with what I am seeing.”

Fourth-grader Kaleb Maguire proved that all tap water in Beeville was the same quality.

He took samples of water at 10 different sites across town and came to the conclusion that because the water originated at the same source — the city’s fresh water plant — the samples contained the same amount of alkalinity, pH and free chlorine.

Fourth-grader Amber Martinez concluded that worms subjected to music were more alert than those not.

And fourth-grader Sam Waters’ project was no doubt much enjoyed by his pet pooch, Lucky.

Sam wanted to know which meat his dog would like more. Turns out Lucky preferred chicken over both hotdogs and sausage.

Fifth-grader Savannah Gonzales found out that ants prefer cheese over sugar, but classmate Misty Nienhouse concluded that ants preferred sugar over cheese. Tessa Giannini’s science project also seemed to prove that ants preferred sugar over cheese, bread or anything else.

However, fourth-grader Faith Hernandez conducted a similar experiment and concluded ants preferred cheese over ham.

Yet, Jose Vivesos, a fourth-grader, concluded that ants prefer sugar water over anything else.

Nathanial Martinez, also a fourth-grader, built a working seismograph and demonstrated how it detected and recorded earthquakes.

Fifth-grader Jamison Hunter decided to see if money in the hand made a difference in someone’s heart rate.

He recorded the heart rate of each volunteer without money in their hand, with one dollar bill in their hand, two one dollar bills in their hand and three one dollar bills in their hand.

His conclusion: “From this experiment, I learned that everyone’s heart rate is different by how much money they hold,” he said. “No two people had the same results even with the test being done the same way.”

Temperatures may have cooled in Beeville.  Can we extrapolate Beeville to the entire planet?

The title of the project may be a little bit ambitious.

Beeville fourth grader disproves global warming?

June 7, 2010

John Mashey alerted me to this news story from the online Beeville Bee-Picayune via mySouTex.com:

R.A. Hall fourth-grader is science national champion

R. A. Hall fourth grader Julisa Castillo, national science fair winner?

Hall Principal Martina Villarreal. Read more: mySouTex.com - R A Hall fourth grader is science national champion

R.A. Hall Elementary School fourth-grader Julisa Castillo has been named junior division champion for the 2010 National Science Fair.

Her project, “Disproving Global Warming,” beat more than 50,000 other projects submitted by students from all over the U.S.

Julisa originally entered her project in her school science fair before sending it to the National Science Foundation (NSF) to be judged at the national level.

The NSF panel of judges included former U.S. Vice President Al Gore, 14 recipients of the President’s National Medal of Science, and four former astronauts.

“Before she sent it off, she just had to add more details, citations for her research, and the amount of hours she spent working on it,” said Julisa’s father, J.R. Castillo.

In addition to a plaque, trophy and medal, Julisa has won an all-expenses-paid trip to Space Camp at the U.S. Space & Rocket Center in Huntsville, Ala., which she plans to attend this summer.

The blog of the North County Times (California) has doubts.  There are signs of hoax.  While the Beeville Independent School District does have an R. A. Hall elementary, the list of winners of last December’s science fair does not include Ms. Castillo.  To go from not placing at the local school to winning the national would be quite a feat!

I suspect an error somewhere, perhaps in the title of the project, or in the understanding of what the title implies.

Most of the obvious hoax signs check out against a hoax:  Beeville exists (improbably Texan as the name may be), R. A. Hall is an elementary school in Beeville ISD.  The principal of R. A. Hall is Martina Villareal.  Beeville has a guy named J. R. Castillo (listed as Julisa’s father in the photo caption), and his photos at the site promoting his music shows photos of a guy who looks a lot like the guy in the photo here.  Most hoaxers wouldn’t go so far for accuracy on details.

Fun little mystery.  I have made inquiries with the newspaper, and hope to follow up with the school.  Stay tuned.  There may be a great little science project somewhere in here.

_____________

See update here: Quick summary, big title, project not quite filling those shoes. I’ve made inquiries at the paper and school district without answers; there’s more to the story, but not much.  A good project with a misleading title, for those who would be misled by a 4th grade science fair project.


Hummingbird moth in the lavender at 6:00 a.m.

Kathryn planted lavendar on the front walk.  It crowds the walk, so you have to brush by it coming in or going out of the house, and sometimes you get a great whiff of lavender.

On the way back from getting the newspaper this morning I was greeted by this hummingbird moth sipping its breakfast from the lavender blossoms.  It was too dark for natural lighting.  The flash froze the wings, and exposed colors that you can’t see as the little creature hovers.

Probably a Hyla lineata, no?

Measles vaccine: Britain bans anti-vaxxer Wakefield

May 25, 2010

Dr. Andrew Wakefield’s license to practice medicine in Britain was stripped away by British authorities earlier today, due to his “ethical lapses” in conducting research against measles vaccines.

Wakefield’s research claims, published in the distinguished medical journal Lancet in 1998, sparked a worldwide hysteria over the claimed link of Mumps-Measles-Rubella vaccine (MMR) to autism.  The journal earlier withdrew the article when the research was exposed as faulty and reaching erroneous conclusions.

Lancet retracted the paper earlier this year.

Effects of Wakefield’s errors ripple across the globe, as children pay the price with measles rates up worldwide, especially in Africa, and in North AmericaRob Breckenridge described the damage for the Calgary Herald:

However, Wakefield’s foul legacy is very much consequential. His latest comeuppance is hopefully a small step in undoing that legacy’s damage, but much damage has already been done.

Wakefield authored a now-discredited paper published in 1998 in The Lancet, which implied that the MMR (measles-mumps-rubella) vaccine was linked to autism.

Numerous studies have shown no such link exists, but Wakefield’s research had the predictable effect of scaring people away from the MMR vaccine. Vaccination rates plummeted in the U.K., and the number of measles cases soared.

In 2008 in the U.K., there were almost 1,400 cases of measles compared with 56 the year Wakefield’s paper was published. In 2006, a 13-year-old boy died from measles — the first time in 14 years such a death had been recorded.

On top of the multiple studies rejecting the MMRautism link, The Lancet issued a formal retraction of Wakefield’s paper in February, citing his unethical and irresponsible conduct.

Once a disease like measles becomes rare, we tend to drop our guard, either forgetting how serious it is or assuming it can never come back. As we’ve seen in the U.K. it can come back with a vengeance. Unfortunately, it’s not only the U.K. where we’re learning that lesson.

This month, Alberta Health Services confirmed five cases of measles in the Calgary area. Given our lack of recent experience with measles — there was only one case provincewide in 2009 — AHS offered a primer on the disease.

Measles is extremely contagious, meaning one need not have close contact with an infected person. There is no cure, but vaccination can prevent it. There are still pockets of the province where vaccination rates are low and measles cases there have been higher.

Southwestern Alberta is one of those regions. Not only has measles made a comeback there — a 2000 outbreak closed a Lethbridge-area private school — but cases of mumps and whooping cough have been documented over the past two years.

In B.C., 87 measles cases have been confirmed this year. It’s believed many stem from infected out-of-country visitors at the Vancouver Olympics.

All cases involve people who were either not vaccinated, or only partially vaccinated. Eight cases were associated with a single household, where no one had been vaccinated.

As Typhoid Mary denied she could be the cause of the deaths of the people she cooked for, and so continued cooking, Wakefield promises to keep up his campaign for measles.

The rear of the horse that measles rode in on

May 23, 2010

Why would people fail to inoculate their kids against measles, and thereby contribute to deadly epidemics?

There was this guy in Britain, Andrew Wakefield, who published a study suggesting a link between measles vaccines and autism.  But it turned out his research didn’t support that claim.  Then it turned out he was under contract to produce a paper that made that claim regardless the science, for a lawsuit.

Darryl Cunningham created a concise, 15-page graphic accounting of the story of how the misdeeds of one physician led to a world-wide, child-killing panic.  If you do not know the story, go read it.  You should be troubled by the story it tells.  Be sure to read it through.  Cunningham is thorough in his debunking of the hysteria the anti-vaxxers promote, and you should know it all.

Darryl Cunningham's graphic story, "The Facts in the Case of Dr. Andrew Wakefield"

Another page from Darryl Cunningham's graphic story, "The Facts in the Case of Dr. Andrew Wakefield" about the motivations behind the hysteria.

Then send a copy to Jenny McCarthy, or anyone else who carries the torch of ignorance-based hysteria against vaccines and in favor of disease.

Dr. Wakefield’s original paper was retracted by the publisher — it’s no longer considered valid science.  It’s a hoax.  No subsequent research confirmed any links to autism.  Serious, large-scale follow-up studies revealed no connection whatsoever between measles vaccine and autism.

Measles is a nasty disease, tough to eradicate, and working hard to come back and get your children and grandchildren.  Don’t be suckered.

Andrew Wakefield created a hoax.  Those who rely on his study rely on bogus science, voodoo science.  History tells us that, if we stop the fight against measles, people will die.

Annals of Global Warming: NOAA team finds oceans heated up since 1993

May 21, 2010

News from NOAA and NASA:

The upper layer of the world’s ocean has warmed since 1993, indicating a strong climate change signal, according to a new study. The energy stored is enough to power nearly 500 100-watt light bulbs per each of the roughly 6.7 billion people on the planet.

“We are seeing the global ocean store more heat than it gives off,” said John Lyman, an oceanographer at NOAA’s Joint Institute for Marine and Atmospheric Research, who led an international team of scientists that analyzed nine different estimates of heat content in the upper ocean from 1993 to 2008.

From NOAA: John Lyman (left) holds an expendable bathythermograph or XBT, a device that was dropped from ships to obtain temperature. Gregory Johnson (right) holds an ARGO Float, an autonomous, free-floating ocean device that collects a variety of data, including temperature. (NOAA photo, 2010)

The team combined the estimates to assess the size and certainty of growing heat storage in the ocean. Their findings will be published in the May 20 edition of the journal Nature. The scientists are from NOAA, NASA, the Met Office Hadley Centre in the United Kingdom, the University of Hamburg in Germany and the Meteorological Research Institute in Japan.

“The ocean is the biggest reservoir for heat in the climate system,” said Josh Willis, an oceanographer at NASA’s Jet Propulsion Laboratory and one of the scientists who contributed to the study. “So as the planet warms, we’re finding that 80 to 90 percent of the increased heat ends up in the ocean.”

A warming ocean is a direct cause of global sea level rise, since seawater expands and takes up more space as it heats up. The scientists say that this expansion accounts for about one-third to one-half of global sea level rise.

Combining multiple estimates of heat in the upper ocean – from the surface to about 2,000 feet down – the team found a strong multi-year warming trend throughout the world’s ocean. According to measurements by an array of autonomous free-floating ocean floats called ARGO as well as by earlier devices called expendable bathythermographs or XBTs that were dropped from ships to obtain temperature data, ocean heat content has increased over the last 16 years.

The team notes that there are still some uncertainties and some biases.

“The XBT data give us vital information about past changes in the ocean, but they are not as accurate as the more recent Argo data,” said Gregory Johnson, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory. “However, our analysis of these data gives us confidence that on average, the ocean has warmed over the past decade and a half, signaling a climate imbalance.”

Data from the array of Argo floats­ – deployed by NOAA and other U.S. and international partners ­– greatly reduce the uncertainties in estimates of ocean heat content over the past several years, the team said. There are now more than 3,200 Argo floats distributed throughout the world’s ocean sending back information via satellite on temperature, salinity, currents and other ocean properties.

NOAA’s mission is to understand and predict changes in the Earth’s environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Visit us on Facebook.

Update, February 16, 2011: Interesting that this research got so little play in mainstream media, more curious that those who contend global warming and/or the need to do anything about it have buried it so well.  RealClimate noted that denialist Larry Bell, writing in Forbes, even cited the work of this team, but claiming a contrary resultEven Watts Up appears to have gone silent on this after a curtain-raiser post on the project.  Odd.


Good news: Warming probably won’t expand malaria much

May 19, 2010

A paper in the May 20 edition of Nature reports that global warming probably won’t expand the range of malaria much.  That’s good news.

Here’s the press release from the University of Florida, touting the paper written by two University of Florida researchers, among others:

Scientists: Malaria control to overcome disease’s spread as climate warms

Filed under Environment, Health, Research on Wednesday, May 19, 2010.

GAINESVILLE, Fla. — Contrary to a widespread assumption, global warming is unlikely to expand the range of malaria because of malaria control, development and other factors that are at work to corral the disease.

So concludes a team of scientists including two University of Florida researchers in a paper set to appear May 20 in the journal Nature.

Scientists and public policy makers have been concerned that warming temperatures would create conditions that would either push malaria into new areas or make it worse in existing ones. But the team of six scientists, including David Smith and Andy Tatem, faculty members with UF’s biology and geography departments and both at UF’s Emerging Pathogens Institute, analyzed a historical contraction of the geographic range and general reduction in the intensity of malaria — a contraction that occurred over a century during which the globe warmed. They determined that if the future trends are like past ones, the contraction is likely to continue under the most likely warming scenarios.

“If we continue to fund malaria control, we can certainly be prepared to counteract the risk that warming could expand the global distribution of malaria,” Smith said.

The team, part of the Wellcome Trust’s multinational Malaria Atlas Project, noted that malaria control efforts over the past century have shrunk the prevalence of the disease from most of the world to a region including Sub-Saharan Africa, Southeast Asia and South America, with the bulk of fatalities confined to Africa. This has occurred despite a global temperature rise of about 1 degree Fahrenheit, on average, during the same period.

“The globe warmed over the past century, but the range of malaria contracted substantially,” Tatem said. “Warming isn’t the only factor that affects malaria.”

The reasons why malaria has shrunk are varied and in some countries mysterious, but they usually include mosquito control efforts, better access to health care, urbanization and economic development. The banned pesticide DDT was instrumental in ridding the disease from 24 countries in Southern Europe, the former Soviet Union and elsewhere in the world between 1955 and 1969, Smith said. Researchers debate how the U.S. defeated malaria, but the reduction of mosquito breeding grounds, improved housing and reduced emphasis on agriculture that comes with development — and the reduced risk of bites that accompanies urbanization – probably played a role, Smith said.

“There is no one tale that seems to determine the story globally,” Tatem said. “If we had to choose one thing, we would guess economic development, but that’s kind of a cop out” because the specific mechanisms may still remain unclear, and controlling malaria might also help to kick-start development.

In any case, current malaria control efforts such as insecticide-treated bed nets, modern low-cost diagnostic kits and new anti-malarial drugs, have proved remarkably effective, with more and more countries achieving control or outright elimination. Unless current control efforts were to suddenly stop, they are likely to counteract the spread of mosquitoes or other malaria-spreading effects from anticipated temperature increases, Smith said.

Simon Hay, an author of the Nature paper and one of the chief architects of the Malaria Atlas Project, noted that modern malaria control efforts “reduce transmission massively and counteract the much smaller effects of rising temperatures.”

“Malaria remains a huge public health problem, and the international community has an unprecedented opportunity to relieve this burden with existing interventions,” he said. “Any failure in meeting this challenge will be very difficult to attribute to climate change.”

Key to controlling malaria is the treatment of the disease in human victims.  Malaria parasites must spend part of their life cycle in humans; if medical care can cure humans, mosquitoes have no well of the disease to draw from, to spread it.

This paper says that global warming won’t spread the disease, so long as medical care and local health officials can keep effective treatments — a complete cure for human victims — coming quickly.

Global warming on other planets? Don’t be a dumb bunny

May 18, 2010

Do you weary, as I do, of global warming disbelievers* who say, with a straight face, that global warming is no problem on Earth because other planets in our solar system are also warming?

I mean, they say it as if there were a connection, as if it meant anything — does it weary you?

Eli Rabett is doing the hard-but-necessary academic task of combing through the official responses EPA scientists gave to comments on their proposals to regulate greenhouse gases.  Such regulations must be published in the Federal Register, and upon publication they must be open to public comment for a while, usually at least 30 days.

Ain’t our democratic republic wonderful?  Agencies are required to answer the comments, even stupid comments, even stupid comments from political hacks bent on making political points instead of shining light.

And, Eli has teased out EPA’s responses to the claims that warming on Earth is no problem because there is warming on other planets, so we can blame warming on God or the Sun, and do nothing.

Um, EPA doesn’t think so.  Read it here, at Eli’s burrow.

(I’ll wager Eli is one who knows his burro from a burrow.)

Ken Ham and Atlantis

May 16, 2010

Uh-oh.  Did P. Z. Myers see the name of the commanding officer of the space shuttle Atlantis on the current flight, STS-132?

Short press release from NASA:

Sun, 16 May 2010 06:48:08 -0500

Commander Ken Ham [emphasis added] and the crew of Atlantis performed the Terminal Initiation burn at 7:40 a.m. EDT, firing the left Orbital Maneuvering System engine for nine seconds to place the shuttle on the final path for its 10:27 a.m. docking to the International Space Station. When Atlantis is about 600 feet from the station, Ham will maneuver Atlantis through a backflip rotation to expose the heat shield to station crew members who will use digital cameras to photograph Atlantis’ upper and lower surfaces through windows of the Zvezda Service Module. Oleg Kotov will use a 400mm lens, and T.J. Creamer, Soichi Noguchi and Tracy Caldwell Dyson all will use 800mm lenses. The photos will be transmitted to Mission Control for evaluation by imagery experts and mission managers to determine whether the heat shield sustained any damaged during launch.

Not only is it not the same Ken Ham, I’ll wager they are completely unrelated, and that they’ve never met.  I wonder how the astronaut lives with people confusing him with the Ken Ham of the creationism cult.  Perhaps creationists stray into the real process of space exploration so rarely that no one has made the connection yet.

Ken Ham, creationist

. . . this Ken Ham, who doesn't "believe" in much of the science that gets the other Ken Ham into orbit.

This Ken Ham, the astronaut (NASA photo), is not to be confused with . . .


“America’s Climate Choices” – the video

May 14, 2010

This video, from 2009, explains why the National Academies will release four reports on climate change, three of them next Wednesday.

NAS explains it this way at their website:

As part of its most comprehensive assessment to date, the National Research Council – the operating arm of the National Academy of Sciences and National Academy of Engineering – will release three new reports examining how the nation can combat the effects of global warming. One focuses on the science to better understand climate change, and the others review options for limiting the magnitude of and adapting to the impacts of global warming. The reports are part of a congressionally requested suite of studies known as America’s Climate Choices.


National Academies report, “America’s Climate Choices” – coming May 19, with webcast

May 14, 2010

I get e-mail from the good press people at the National Academies (of Science, Engineering, and Medicine):

America’s Climate Choices Reports to be Released May 19 at a Public Briefing

On May 19th, three reports in the America’s Climate Choices suite of studies will be released at a public briefing that begins at 10 a.m. EDT in the Lecture Room of the National Academy of Sciences building, 2100 C St., N.W., Washington. The reports are: Advancing the Science of Climate Change, which focuses on the scientific evidence regarding human-induced climate change and future research needs; Limiting the Magnitude of Future Climate Change, which assesses options for limiting greenhouse gas emissions and taking other actions to reduce the magnitude of climate change; and Adapting to the Impacts of Climate Change, which focuses on options to improving the nation’s capacity to adapt to climate change impacts.

Ralph J. Cicerone, president of the National Academy of Sciences, will deliver opening remarks, and members of the panels that authored the reports will discuss the reports findings and take questions.

America’s Climate Choices also includes two additional reports that will be released later this year: Informing an Effective Response to Climate Change will examine how best to provide decision makers with information on climate change, and an overarching report that looks across the topics of the four panel reports to offer an integrated view of the challenges and opportunities in the nation’s efforts to confront climate change.

The public is invited to the briefing and should RSVP to attend at  americasclimatechoices.org. Those who cannot attend may watch a live video webcast and submit questions at http://www.national-academies.org.

This address works better for giving your RSVP to attend.  A fourth report pends:

Still upcoming is the fourth and final panel report, Informing an Effective Response to Climate Change.


Wall Street Journal’s DDT-fueled war on science

May 12, 2010

I don’t subscribe to the Wall Street Journal — their discounts to educators are lousy.

So I missed this editorial when it ran on April 24, 2010 (page A12), “DDT and population control – malaria still kills one million every year.”

Nominally, that should be good news.  At the peak of DDT use in the early 1960s, malaria killed about 3 million people annually.  By the time we banned DDT use on cotton crops in the U.S., the death toll was still about 2 million people annually.  From the heyday of DDT, we’ve decreased malaria’s death toll, to less than half what it was.

Editorial writers at the Journal don’t let facts get in their way when they go off on a misdirected political jihad or crusade.  Gross error Number 1:  They mislead readers about the facts.

They are claiming that a million is too many (it is), but they claim that the total would be significantly less if only Americans would attack Africa with poison.  We have trouble enough with wars in Afghanistan and Iraq, it seems to me.  There is no indication that we could reduce malaria rates with a lot of extra poison.  Malaria is a parasite in human blood.  To defeat the disease we have to defeat the infections in humans.  Mosquitoes just spread the disease from one human to another.  DDT does not cure malaria in humans; it is one preventive device of limited effectiveness.

What are they on about?

The Journal’s editorial writers said:

Environmental activists this week marked the 40th anniversary of Earth Day, which happened to fall three days before World Malaria Day. Insofar as Earth Day politics have contributed to today’s malaria epidemic, the two events are related.

You could see this one coming.  The reactionaries at the editorial seek out opportunities to criticize environmentalists, whose cause they see as anti-business.   The Journal’s editorial page usually carries an op-ed piece by Hoover Institute maven Henry I. Miller about once a year (see here, for example), claiming we need DDT to fight West Nile virus.  We don’t, of course.  West Nile virus-carrying mosquitoes are best fought with other pesticides, when pesticides are used.  They need to be hit before adulthood, while they are still larva, in the water.  DDT is exactly wrong for such applications.  But Miller’s piece comes around almost every year, as soon as the first West Nile virus infections in humans are noted.

So, since they so soundly disregard science on that diatribe, why not here, too?  DDT offers a great target for Tea Baggers, Know-Nothings, and truth bashers.  Most of the history of DDT was written before the internet, so it’s easier to spread falsehoods without contradiction.

Disinformation.  Propaganda.  Shame on the Wall Street Journal.

Earth Day and World Malaria Day are related in this way:  Environmentalists warned us that doing the wrong stuff in the environment would make it harder to fight malaria, and they were right.  People who resist clean air and clean water legislation also resist legislation to stop poisoning our planet.  Those people rarely do anything to fight malaria, either.  Human comfort, human health, human survival, is not what they are concerned about.

Earth Day founder Gaylord Nelson, a U.S. Senator from Wisconsin, was a leading opponent of the insecticide DDT, which remains the cheapest and most effective way to combat malarial mosquitoes.

Gaylord Nelson, the father of Earth Day, was governor of Wisconsin when the University of Wisconsin did the first studies showing that songbirds and raptors in Wisconsin were being wiped out by DDT. We should expect him to be an opponent of indiscriminate use of the stuff.  His state was on the road to ruin, and long before the federal government acted against DDT, Wisconsin had laws and regulations to limit its use.  Wisconsin’s wild populations recovered a bit more quickly because Wisconsin had acted.

Nelson also knew that, in the U.S., malaria was conquered by 1939 (according to the Centers for Disease Control).  DDT came along in 1946, seven years later.  While DDT was used to control mosquitoes in the U.S., it was for no disease control reasons — that was why so many people opposed the rather pointless use of the stuff.  And I suspect Nelson was savvy enough to know that DDT has not been the cheapest means of controlling mosquitoes for several years.  One application of DDT in Africa costs about $12.00, for the professional who must apply it, and the testing to determine whether DDT will even work.  One application lasts about six months.  So, for a year’s protection, DDT costs about $24.00 per house, per year.

Bednets cost about $10.00, and last about five years.  That works out to $2.00 year.  For $24.00, you could provide a dozen different nets in a home, though most homes would use them only to protect children.

Moreover, recent test runs in Africa show DDT about 25% to 50% effective in reducing malaria incidence, while bednets are about 50% to 85% effective.  Nets are cheaper and more effective.

Doesn’t the Wall Street Journal have fact checkers?  Or do they just not care about the facts?

Rachel Carson’s 1962 book, “Silent Spring,” misleadingly linked pesticides to cancer and is generally credited with popularizing environmental awareness.

Wrong on three fronts.  Carson noted that the family of chemicals from which DDT comes might have links to cancer, but she did not make the claim that DDT is carcinogenic.  DDT was banned because it’s a long-term, deadly poison that destroys ecosystems.  Cancer in humans was not a part of the equation.

However, DDT is now known to be a weak human carcinogen.  Every cancer-fighting agency on Earth lists it as a “probable human carcinogen” (it is confirmed to cause cancer in other mammals).  Can’t the Wall Street Journal find the phone number of the American Cancer Society?

DDT earned its ban because of 20 years of research data by 1972, showing that DDT kills virtually everything it comes in contact with that is smaller than a large man, and it destroys ecosystems.  Talking about DDT’s carcinogenicity is a red herring.  Carson didn’t claim DDT was a significant cause of cancer, nor was DDT banned from agricultural use because anyone thought it was a significant cause of cancer.  Yes, DDT is a weak human carcinogen, contrary to the Journal’s implication; but no, that’s not why it was banned.

Carson’s book certainly ignited concerns about human activities affecting environment other than land development.  But “environmental awareness” is as old as our nation, at least.  A hundred years prior to Rachel Carson’s book, the U.S. set aside the world’s first National Park, Yellowstone.  60 years earlier, Teddy Roosevelt and Gifford Pinchot led the drive to conserve the nation’s forests.  The Soil Conservation Service, a New Deal program, worked to save soil on farms and unimproved areas, a good 30 years before Carson’s book.  Environmental awareness is an almost-congenital trait in Americans.  Rachel Carson sounded alarms about new reactive chemical combinations.  Americans were already alert to the need to save soil, water, air and wild spaces.

We banned DDT to save our crops and to save our wildlife.  Those are good reasons to keep the ban today.

But other leading greens of the period, including Nelson, biologist Paul Ehrlich and ecologist Garrett Hardin, were also animated by a belief that growth in human populations was harming the environment.

Nelson thought the U.S. needed to slow immigration (see more below).  Ehrlich feared a massive round of starvation, which was staved off only with the Green Revolution and billions of dollars of foreign aid money, the good luck of our having Norman Borlaug and the Rockefeller Foundation, and major economic change in nation’s like India and China.  Hardin pointed out that even the best intentioned people needed a structure to encourage them to conserve, else conservation would not take place.

They all recognized that while any human could minimize her impact on the natural world, no one person could ameliorate all the effects of billions of people.

“The same powerful forces which create the crisis of air pollution also are threatening our freshwater resources, our woods, our wildlife,” said Nelson. “These forces are the rapid increase in population, industrialization, urbanization and scientific technology.”

Notice, please, that Sen. Nelson did not suggest humans should do anything to cause or encourage massive human death (nor did the Journal do the courtesy of noting where they quoted him from).  He merely notes that air pollution and water pollution, and a lack of freshwater, are created by human populations, industry, urban sprawl and technology.  All of these things threaten human health.  Nelson is concerned that we not add to human illness and misery.  That’s not what the Journal’s editorial wants you to think, however.  It will suggest instead that Nelson urged more human suffering and death.

How craven must an editorial board be to accuse good people, falsely, of such sins?

In his book “The Population Bomb,” Mr. Ehrlich criticized DDT for being too effective in reducing death rates and thus contributing to “overpopulation.”

I doubt it.  I can’t find anything quite to that description in my copy of the book.  It’s a common internet legend (one level dumber than urban legend) — but shouldn’t the Wall Street Journal have higher standards than to use for documentation, “my cousin Clem heard a story about a person his aunt once knew?”

Hardin opposed spraying pesticides in the Third World because “every life saved this year in a poor country diminishes the quality of life for subsequent generations.”

Now the Journal is making things up.  In the essay from which the Journal quotes him, Hardin wrote about the dangers of uncontrolled immigration and population growth — almost sounding like an angry Arizona Tea Partier at times — but never did he get close to suggesting that we should not suppress malaria, for any reason.  (Wise readers may wish to see what Hardin actually said, where he really went awry if he did, and how his words resonate today, at his essay, “Living on a Lifeboat.”  Writers at the Journal should be ashamed of savaging the reputation of a guy who is so much in tune with what they usually write.  Notice Hardin does not mention DDT, use of pesticides in foreign nations, malaria, nor any other disease.  He rails at starvation, however.)  When the Wall Street Journal engages in fiction, shouldn’t they let us know?

For these activists, malaria was nature’s way of controlling population growth, and DDT got in the way.

Gee, in context, that’s all fiction. Never did Sen. Gaylord Nelson claim malaria was a good population control tactic, nor that we should stop using DDT to allow more people to die. Those are whole cloth lies. Never did Garrett Hardin say either of those things. Never did Paul Ehrlich say those things.

For anti-science activists, like the writers at the Wall Street Journal’s editorial page, falsehoods have become coin of the realm, and DDT is just one more sciency thing to try to use as whip against political opponents. The serious question is, why is the Wall Street Journal opposed to clean air and clean water?  Why are they trying to politicize things at all?

The writers at the Journal continue:

Today, malaria still claims about one million lives every year—mostly women and children in sub-Saharan Africa. There’s no evidence that spraying the chemical inside homes in the amounts needed to combat the disease harms humans, animals or the environment. Yet DDT remains severely underutilized in the fight against malaria because the intellectual descendants of Senator Nelson continue to hold sway at the World Health Organization and other United Nations agencies.

Full disclosure would be good here.  Malaria death rates are at the lowest point in history, at least since 1900.  Yes, too many die — but it’s not the fault of “not enough DDT.”  No nation that uses DDT has ever succeeded in eradicating malaria with pesticides alone.  Only those nations that assaulted malaria from the  human side, treating malaria in human victims, have been successful in eradicating the disease.  DDT use was essentially suspended in Africa by the World Health Organization in about 1965, because overuse of DDT in agriculture had bred mosquitoes that are resistant and immune to the stuff.  No amount of DDT spraying, anywhere, can reverse that.  Spraying DDT where mosquitoes are unaffected by it, is stupid.

Plus, studies indicate a correlation between DDT use, even in those small amounts, and premature deaths to children in the households sprayed.  DDT is not harmless.  DDT is not benign.

DDT has never been banned in Africa, and even under the 2001 Persistent Organic Pesticides Treaty (POPs) DDT has a special carve out to keep it available to fight malaria, despite its being a destroyer of worlds.  So implicit in the Journal’s screed here is that Africans are too stupid or lazy to use a substance that would save their children and themselves from malaria, though it’s available relatively cheaply.

Is DDT “underutilized?”  Again we should ask, why would anyone use DDT where it is not effective? Then we should ask, who would use DDT in fighting disease in Africa, and do they use it?  It turns out that DDT is not completely superfluous to all mosquito populations.  But testing is required to be sure DDT will work — were an organization to use ineffective pesticides, thousands could die, and the testing is therefore a preservation of human life.  And, because of past incidents in Africa, for example when DDT killed off the fish local populations depend on for their food, DDT use is extremely limited, to indoor applications only, and only by trained professionals who limit its spread.

WHO has been using DDT in Africa for indoor residual spraying (IRS) since the 1950s.  Use was slowed when DDT’s effectiveness was compromised.  In recent years WHO held a press conference on DDT to encourage locals who fear DDT poisoning to go along, and since 2005 DDT’s effectiveness appears to be dropping.  But DDT is available for use wherever it is needed to fight malaria in Africa.

Is the Wall Street Journal calling for mass poisoning of Africa?  What else could they be talking about?  Why would they call for such a thing?

The Journal claims WHO and other UN agencies are “under the sway” of Sen. Nelson, and that’s bad?  Let’s be clear:  Nelson didn’t oppose use of DDT in Africa to fight malaria.  UN’s WHO is the leading continent-wide advocate of proper use of DDT to fight malaria.  If the Journal claims that current, appropriate use of DDT is too little, what is the Journal advocating?

The good news is that the Obama Administration has continued the Bush policy of supporting DDT spraying in Zambia, Mozambique and other countries where the locals want it used. “Groups like the Pesticide Action Network have lobbied the U.S. Agency for International Development to stop spraying DDT, and Obama is ignoring them so far,” says Richard Tren of Africa Fighting Malaria, an advocacy group. “They’re prioritizing what makes sense from a science and public health point of view.”

Let’s be clear:  The Bush administration refused to allow U.S. money to be used to purchase DDT, or to use DDT, until about 2005.  Environmental Defense, the organization that first sued to stop DDT use in the U.S., argued for years that DDT should be allowed in the limited use WHO proposed, but Bush’s people stood firmly opposed, though never explaining why.  In any African nation where local people want DDT, it’s freely available with other money, of course.  So U.S. opposition, bizarre as it was, was not and is not a barrier to DDT use.

Most environmental groups favor beating malaria, and if a bit of DDT carefully controlled will help do the trick, so much the better.  While business lobbyists have falsely impugned environmentalists for years on this point, actual opposition to DDT use has come, in Uganda for example, from business groups.  Tobacco growers claim they fear some DDT will somehow get on tobacco leaves, and that will make the stuff unsaleable in the European Union.  Cotton growers fear any faint traces of DDT will ruin sales of organic cotton to the EU.  These business groups sued to stop DDT use against malaria in Uganda.

But environmental organizations, like ED, the Sierra Club, and others, have been fighting malaria for 40 years.

Which is more than we can say for Richard Tren.  Tren is one of two or three of the leading false propagandists for poisoning Africa in the world.  He tells false tales about Rachel Carson, false tales about DDT’s harms and effectiveness, and as best I can tell he has never lifted one finger or written one check to fight malaria himself, while taking tens of thousands of dollars to spread his false tales.

There are dozens of noble malaria fighters out there whose opinions we should seek — Socrates Litsios, the late Fred Soper, to mention two.  Why does the formerly august Wall Street Journal use Richard Tren as a source, when there are authoritative people handy to talk?

DDT helped to eradicate malaria in the U.S. and Europe after World War II, and the U.S. is right to take the lead in reforming public health insecticide policy and putting the lives of the world’s poor above green ideology.

Printed in The Wall Street Journal, page A12

According to the history of malaria at the CDC, malaria was essentially wiped out in the U.S. by 1939.  DDT was not available for use for another seven years.  Malaria was gone from northern Europe by World War II.  DDT was a tool in the final eradication of the disease in Italy and Greece.  But the main campaign against malaria was in curing the disease in humans, before the mosquito populations could rise up.

Among the nasty facts of science the Journal either does not know, or refuses to say, DDT can’t eradicate mosquitoes.  In anti-malaria campaigns, DDT is used to knock down the mosquito populations temporarily, so that the disease can be cured in humans.  Mosquito populations will quickly rise again, and in even greater numbers — but if there is no human reservoir of malaria parasites for mosquitoes to draw from, they cannot spread the disease.  Malaria parasites must spend part of their life cycle in humans, and part in mosquitoes.

Curing malaria in humans is the tough part.  It requires money to improve medical care, for accurate and speedy diagnoses, and for prompt and complete treatment of the disease in each patient.  Preventing malaria is aided greatly by better-built homes with screens on windows, the sort of stuff that requires people to have more than subsistence incomes.  So beating malaria generally requires economic development, too.

How much easier is it to bash environmentalists than to confront the real causes of malaria.  Bashing environmentalists won’t do anything to relieve human suffering nor eliminate the disease, so we can bash environmentalists again next World Malaria Day, and next Earth Day — all at no cost to us, safe in our Wall Street Journal offices in Manhattan, New York, U.S.A.  The Journal has fallen victim to bold purveyors of junk and voodoo science, and bogus and voodoo history.  Shame on the Journal.

Curing the disease in humans means the mosquitoes are mere nuisances, and no longer vectors of disease.  Killing the mosquitoes with poison means the disease will be back with a vengeance in a few weeks or months.  Curing humans is more difficult, and more costly — but it saves lives and can save Africa.  We cannot poison Africa to health.

It’s curious, though:  How did they get so poisoned by DDT, up in that office building?
