Earth Day/Lenin’s Birthday hoax

April 22, 2010

One surefire way to tell an Earth Day post is done by an Earth Day denialist:  They’ll note that the first Earth Day, on April 22, 1970, was an anniversary of the birth of Lenin.

Coincidentally, yes, Lenin was born on April 22 (new style calendar; it was April 10 on the calendar when he was born — but that’s a digression for another day).

It’s a hoax.  There is no meaning to the first Earth Day’s falling on Lenin’s birthday — Lenin was not prescient enough to plan his birthday to fall in the middle of Earth Week, a hundred years before Earth Week was even planned.

My guess is that only a few really wacko conservatives know that April 22 is Lenin’s birthday (was it ever celebrated in the Soviet Union?).  No one else bothers to think about it, or say anything about it, nor especially, to celebrate it.

Wisconsin’s U.S. Sen. Gaylord Nelson, usually recognized as the founder and father of Earth Day, told how and why the organizers came to pick April 22:

Senator Nelson chose the date in order to maximize participation on college campuses for what he conceived as an “environmental teach-in.” He determined the week of April 19–25 was the best bet; it did not fall during exams or spring breaks, did not conflict with religious holidays such as Easter or Passover, and was late enough in spring to have decent weather. More students were likely to be in class, and there would be less competition with other mid-week events—so he chose Wednesday, April 22.

In his own words, Nelson spoke of what he was trying to do:

After President Kennedy’s [conservation] tour, I still hoped for some idea that would thrust the environment into the political mainstream. Six years would pass before the idea that became Earth Day occurred to me while on a conservation speaking tour out West in the summer of 1969. At the time, anti-Vietnam War demonstrations, called “teach-ins,” had spread to college campuses all across the nation. Suddenly, the idea occurred to me – why not organize a huge grassroots protest over what was happening to our environment?

I was satisfied that if we could tap into the environmental concerns of the general public and infuse the student anti-war energy into the environmental cause, we could generate a demonstration that would force this issue onto the political agenda. It was a big gamble, but worth a try.

At a conference in Seattle in September 1969, I announced that in the spring of 1970 there would be a nationwide grassroots demonstration on behalf of the environment and invited everyone to participate. The wire services carried the story from coast to coast. The response was electric. It took off like gangbusters. Telegrams, letters, and telephone inquiries poured in from all across the country. The American people finally had a forum to express its concern about what was happening to the land, rivers, lakes, and air – and they did so with spectacular exuberance. For the next four months, two members of my Senate staff, Linda Billings and John Heritage, managed Earth Day affairs out of my Senate office.

Five months before Earth Day, on Sunday, November 30, 1969, The New York Times carried a lengthy article by Gladwin Hill reporting on the astonishing proliferation of environmental events:

“Rising concern about the environmental crisis is sweeping the nation’s campuses with an intensity that may be on its way to eclipsing student discontent over the war in Vietnam…a national day of observance of environmental problems…is being planned for next spring…when a nationwide environmental ‘teach-in’…coordinated from the office of Senator Gaylord Nelson is planned….”

Nelson, a veteran of the U.S. armed services (Okinawa campaign), flag-waving ex-governor of Wisconsin (Sen. Joe McCarthy’s home state, but also the home of Aldo Leopold and birthplace of John Muir), was working to raise America’s consciousness and conscience about environmental issues.

Lenin on the environment?  Think of the Aral Sea disaster, the horrible pollution from Soviet mines and mills, and the dreadful record of the Soviet Union on protecting any resource.  Lenin believed in exploiting resources, not conservation.

So, why are all these conservative denialists claiming, against history and politics, that Lenin’s birthday has anything to do with Earth Day?

Can you say “propaganda?”

World Malaria Day, 2010 – April 25

April 18, 2010

April 25, 2010, is World Malaria Day.

Malaria plagues too many nations, still.  Between 400 million and 500 million people in the world get infected with one form of the malaria parasites every year.  About a million die, most of those children.  Death disproportionately strikes pregnant women, too.

Life cycle of malaria, from the World Health Organization (WHO)

World Health Organization (WHO) chart on the life cycle of malaria

Advances in medicines and advances in controls of the insects that help transmit the disease led to several campaigns to eradicate the disease over the past 60 years.  Malaria no longer torments most of Europe and most of North America, but it remains a serious, economy-crippling disease across Africa and Asia.

Malaria also poses as a political football.  Over the next couple of weeks you can find dozens of articles on valiant efforts to fight malaria, including the RollBack Malaria Campaign, and efforts by the Gates Foundation and histories of the work of the Rockefeller Foundation.  But you can also find a pernicious political campaign against malaria fighters and “environmentalists,” claiming that DDT is a magic potion that could have ridded the world of malaria by killing off all the mosquitoes, if only that great mass murderer, Rachel Carson, had not imposed her will on the unstable dictators of African nations who did all they could to prove to Ms. Carson that they were environmentally friendly by banning DDT.

All of that is a crock.  But we see it every year.

It’s already shown up in the formerly-known-as-accurate Wall Street Journal, European edition.  (Please watch — I may have more to say on that piece, later.)

Over the next two weeks I will ask myself a hundred times, why do these people fiddle with trying to impugn scientists, physicians and environmentalists, while fevers burn in the brains of children across Africa and Asia?

With action, hope is that we can save the million lives lost annually by stopping malaria, by 2015.  Please consider joining the effort.

You should wonder about that, too.  If you find a good answer, please let me know.

Debunking Monckton’s “no warming” hoax, Part 2

April 17, 2010

So, Maggie Thatcher, his boss, also rejected Christopher Monckton’s preposterous claims against the science of climate change?

Who knew?

It’s clear Christopher Monckton doesn’t know . . . much of value.

Sorta disappointed Peter Sinclair didn’t go after Monckton’s preposterous insults of Jackie Kennedy and Rachel Carson, but there’s only so much debunking one can do in a limited period of time, and so much of Monckton’s work requires debunking, even cries out for debunking.

Is there anything Monckton claims which is not hoax?


Remembering Christa McAuliffe: Teacher talks with North Carolina school kids, from space

April 13, 2010

Sometimes progress is so strong that we forget to note the milestones.

I’m remembering Christa McAuliffe today.

Tomorrow, April 14, Mission Specialists Dottie Metcalf-Lindenburger is scheduled to talk with students at Eastern Guilford High School in North Carolina, and all of the 71,000 students in Eastern Guilford School District.

Metcalf-Lindenburger is one of three teachers selected in 2004 as astronauts.  NASA is committed to help education out.  After the Challenger disaster, and the death of “teacher in space” Christa McAuliffe, NASA finally determined to make teachers into astronauts rather than fly “civilians.”

Bittersweet, but there it is.

Orbiting Space Shuttle Astronauts — Including Former Teacher — Call North Carolina Students

WASHINGTON — Astronauts orbiting 220 miles above Earth will speak with students in Gibsonville, N.C., on Wednesday, April 14. The call with the students and space shuttle Commander Alan Poindexter and Mission Specialists Dottie Metcalf-Lindenburger, Stephanie Wilson and Clay Anderson will take place at 1:06 p.m. EDT at Eastern Guilford High School in Gibsonville.

Eastern Guilford High School is hosting students from Eastern Guilford Middle School, Gibsonville Elementary, McLeansville Elementary, Rankin Elementary and Sedalia Elementary for the downlink. The school also will broadcast the event to the entire Guilford County Schools district, which serves more than 71,000 students.

The astronauts launched Monday, April 5, aboard space shuttle Discovery from NASA’s Kennedy Space Center in Florida. During the 13-day mission to the International Space Station, the crew will deliver science experiments and supplies; take three spacewalks to switch out a gyroscope on the station’s truss, or backbone; install a spare ammonia storage tank and return a used one; and retrieve a Japanese experiment from the station’s exterior.

Metcalf-Lindenburger is one of three teachers selected to fly as shuttle mission specialists in the 2004 Educator Astronaut Class. She operates the shuttle’s robotic arm. Without robotics, major accomplishments like building the station, repairing satellites in space and exploring other worlds would not be possible.

Students have been preparing for the downlink by conducting NASA engineering design challenges and implementing agency robotics resources and activities into K-12 classrooms. A science, technology, engineering and math, or STEM, club was organized to increase participation and interest, particularly by female students.

The school’s guidance department also is collaborating with local universities to help students investigate and explore STEM opportunities beyond graduation. During follow up in-district workshops in April and May, a NASA Aerospace Education Services Program specialist will demonstrate how to access and use NASA resources in K-12 curricula.

Eastern Guilford High School employee Michael Woods, a former Aerospace Education Services Project specialist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and the agency’s Langley Research Center in Hampton, Va., is leading the downlink effort. In December 2009, NASA awarded Guilford County Schools a two-year grant of nearly $1 million to help middle and high school teachers develop science lessons using the space agency’s content.

The event is part of a series with educational organizations in the U.S. and abroad to improve teaching and learning in science, technology, engineering and mathematics. The in-orbit call is part of Teaching From Space, a NASA project that uses the unique environment of human spaceflight to promote learning opportunities and build partnerships with the kindergarten through 12th grade education community.

NASA Television will air video of the astronauts during the downlink. For NASA TV downlink, schedule and streaming video information, visit:

Even Bob Park will pipe down for a day for this (though he’s right, you know).

You’re not using this technology in your classroom?

April 12, 2010

Here’s another opportunity to put real, cutting edge technology in your classroom.  In fact, your kids could probably invent all sorts of new uses for it.

Have you even heard of this stuff?  Can you use it, live, with the equipment you’ve got?

Blaise Aguera y Arcas  of MicroSoft demonstrated augmented-reality maps using the power of Bing maps, Flickr, Worldwide Telescope, Video overlays and Photosynth, to an appreciative and wowed audience at TEDS:

My prediction:  One more advance in computer technology that classrooms will not see in a timely or useful manner.

But have you figured out how to use this stuff in your geography, history, economics or government classes?  Please tell us about it in comments. Give examples and links, please.


Caucasian wingnuts

April 7, 2010

I’m stealing this one completely from P. Z. Myers’ Pharyngula. It’s just too good.

The daffodils are lovely — I recall when they’d bloom just about Easter in Utah, and Washington, D.C.  Here in Dallas, our daffies depart before March 15, often not bothering to stick around until Easter.

But the real treat is the tree in the background.  It’s just another tree early in the spring, not yet leafed out.  But this one is special.

Pterocarya fraxifolia (tree in the background) - common name, "caucasian wingnut"

Its common name is “caucasian wingnut.”  You can’t make this stuff up. Reality is always much more entertaining than fiction.

Wikipedia’s entry is primed for comedy:

Species

There are six species of wingnut.

Another species from China, the Wheel Wingnut with similar foliage but an unusual circular wing right round the nut (instead of two wings at the sides), previously listed as Pterocarya paliurus, has now been transferred to a new genus, as Cyclocarya paliurus.

Uses

Wingnuts are very attractive, large and fast-growing trees, occasionally planted in parks and large gardens. The most common in general cultivation outside Asia is P. fraxinifolia, but the most attractive is probably P. rhoifolia. The hybrid P. x rehderiana, a cross between P. fraxinifolia and P. stenoptera, is even faster-growing and has occasionally been planted for timber production. The wood is of good quality, similar to walnut, though not quite so dense and strong.

Japanese wingnuts?  Chinese wingnuts?  Tonkin wingnuts (for all you Vietnam war historians out there)?

Wow.  Just wow.

Mexico earthquake: What do we know?

April 5, 2010

Baja California — that’s in Mexico, you European readers — got hit with a large earthquake tonight, a 7.2 on the logarithmic Richter Scale according to some early reports. At least one person died; Mexicali, on the border with California, reports many people trapped.  A state of emergency has been declared.

BBC gives the facts:

A 7.2 magnitude earthquake has hit the Mexican peninsula of Baja California, killing at least one person and causing tremors as far away as Nevada.

The quake struck at 1540 (2240 GMT), 26km (16 miles) south-west of Guadalupe Victoria in Baja California, at a depth of 32km, said the US Geological Survey.

Some people are still trapped in their homes in the city of Mexicali, where a state of emergency has been declared.

It was the worst quake to hit the region for many years, officials said.

The US Geological Survey said some 20 million people felt tremors from the largest quake to hit the area since 1992.

My students with Mexico connections tend to come from farther east, and higher in the mountains — I don’t think I have a single student who visits Baja California on breaks.  But the news will prompt questions from them tomorrow.

The U.S. Geological Survey (USGS) tracks earthquakes around the world.  It should have solid information.  Data on the April 4 7.2 quake are here.

Here’s the tectonic summary:

A magnitude 7.2 earthquake occurred at 3:40:40 p.m. (local time at the epicenter) on Sunday, 4 April 2010 in Baja California, approximately 75 km south of the Mexico-USA border. The earthquake occurred at shallow depth (approximately 10 km) along the boundary zone between the North American and Pacific plates. Since earthquakes have been recorded instrumentally, only two similar sized earthquakes have been recorded in the area. The first was the 1892 earthquake estimated at magnitude 7.0-7.2 along the Laguna Salada fault just south of the USA-Mexico border. The second was the 1940 Imperial Valley magnitude 6.9 earthquake which occurred in southernmost California. Today’s event is located nearly in line with these earthquakes along the plate boundary, but is situated farther to the south. There are several active faults in the vicinity of today’s earthquake, and the particular fault that generated this quake has not yet been determined. Faulting is complex in this region, because the plate boundary is transitional between the ridge-transform system in the Gulf of California and the continental transform system in the Salton Trough. Most of the major active faults are right-lateral strike-slip faults with a northwest-southeast orientation, similar in style to the San Andreas fault to the north. Other faults in the vicinity with the same orientation include the Cerro Prieto fault and the Laguna Salada fault.

USGS hosts good maps, too, like this “shake map” (click the map to go to the USGS site for more information):

USGS "shake map" for the April 4 7.2 quake near Mexicali, Mexico

USGS "shake map" for the April 4 7.2 quake near Mexicali, Mexico - Click to go to USGS site

What other questions can we anticipate?  Somebody will ask whether this quake is related to the Haiti and Chilean quakes (probably not closely related).  Somebody will wonder about the Pacific Ring of Fire, and this quake’s relation to volcanoes and general earthquake activity around the Pacific (high relationship).  Someone will want to know about quakes in your area.  Is this the precursor to “the Big One?”

The USGS site is a good place to start on all of those questions.


Parliament’s investigation: Stolen e-mails reveal no wrong-doing by climate scientists

March 31, 2010

As Galileo might have said, “Still the planet warms.”

A committee of England’s Parliament released its report on Hadley Climate Research Unit’s (CRU) stolen e-mails earlier today.  The reports you heard that the scientific case showing global warming with human causation had died, were exaggerated, significantly in error, and hoaxes themselves.

The report comes from the House of Commons’ Science and Technology Committee.  Press release with links and previous releases from the Committee, below:

The disclosure of climate data from the Climatic Research Unit at the University of East Anglia


Report publishedThe Committee published ‘The disclosure of climate data from the Climatic Research Unit at the University of East Anglia‘, HC 387-I, its Eighth Report of Session 2009-10, on Wednesday 31 March 2010. Volume II, the oral and written evidence, was published the same day.

CLIMATE SCIENCE MUST BECOME MORE TRANSPARENT SAY MPs

The Science and Technology Committee today publishes its report on the disclosure of climate data from the Climatic Research Unit (CRU) at the University of East Anglia. The Committee calls for the climate science community to become more transparent by publishing raw data and detailed methodologies.

Phil Willis MP, Committee Chair, said:

“Climate science is a matter of global importance. On the basis of the science, governments across the world will be spending trillions of pounds on climate change mitigation. The quality of the science therefore has to be irreproachable. What this inquiry revealed was that climate scientists need to take steps to make available all the data that support their work and full methodological workings, including their computer codes. Had both been available, many of the problems at CRU could have been avoided.”

The focus on Professor Jones and CRU has been largely misplaced. On the accusations relating to Professor Jones’s refusal to share raw data and computer codes, the Committee considers that his actions were in line with common practice in the climate science community but that those practices need to change.

On the much cited phrases in the leaked e-mails—”trick” and “hiding the decline”—the Committee considers that they were colloquial terms used in private e-mails and the balance of evidence is that they were not part of a systematic attempt to mislead.

Insofar as the Committee was able to consider accusations of dishonesty against CRU, the Committee considers that there is no case to answer.

The Committee found no reason in this inquiry to challenge the scientific consensus as expressed by Professor Beddington, the Government Chief Scientific Adviser, that “global warming is happening [and] that it is induced by human activity”. But this was not an inquiry into the science produced by CRU and it will be for the Scientific Appraisal Panel, announced by the University on 22 March, to determine whether the work of CRU has been soundly built.

On the mishandling of Freedom of Information (FoI) requests, the Committee considers that much of the responsibility should lie with the University, not CRU. The leaked e-mails appear to show a culture of non-disclosure at CRU and instances where information may have been deleted to avoid disclosure, particularly to climate change sceptics. The failure of the University to grasp fully the potential damage this could do and did was regrettable. The University needs to re-assess how it can support academics whose expertise in FoI requests is limited.


Committee announcementOn 22 January the Science and Technology Committee announced an inquiry into the disclosure of climate data from the Climatic Research Unit at the University of East Anglia.  Commenting on the material which the Committee has received since the announcement the Chairman, Phil Willis MP, said:

The Committee has been receiving a steady stream of contributions to the inquiry, for which it is grateful.  I would like to take this opportunity to emphasise that the focus of the inquiry is the implications of the disclosures for the integrity of scientific research and the terms of reference and scope of the Independent Review announced on 3 December 2009 by UEA.  It is not an inquiry into global warming. In the time remaining before the General Election the Committee would not have time to carry out such an inquiry.


Terms of Reference
The Science and Technology Committee today announces an inquiry into the unauthorised publication of data, emails and documents relating to the work of the Climatic Research Unit (CRU) at the University of East Anglia (UEA). The Committee has agreed to examine and invite written submissions on three questions:—What are the implications of the disclosures for the integrity of scientific research?

—Are the terms of reference and scope of the Independent Review announced on 3 December 2009 by UEA adequate (see below)?

—How independent are the other two international data sets?

Background

On 1 December 2009 Phil Willis, Chairman of the Science and Technology Committee, wrote to Professor Edward Acton, Vice-Chancellor of UEA following the considerable press coverage of the data, emails and documents relating to the work of the Climatic Research Unit (CRU). The coverage alleged that data may have been manipulated or deleted in order to produce evidence on global warming. On 3 December the UEA announced an Independent Review into the allegations to be headed by Sir Muir Russell.

The Independent Review will:

1. Examine the hacked e-mail exchanges, other relevant e-mail exchanges and any other information held at CRU to determine whether there is any evidence of the manipulation or suppression of data which is at odds with acceptable scientific practice and may therefore call into question any of the research outcomes.

2. Review CRU’s policies and practices for acquiring, assembling, subjecting to peer review and disseminating data and research findings, and their compliance or otherwise with best scientific practice.

3. Review CRU’s compliance or otherwise with the University’s policies and practices regarding requests under the Freedom of Information Act (‘the FOIA’) and the Environmental Information Regulations (‘the EIR’) for the release of data.

4. Review and make recommendations as to the appropriate management, governance and security structures for CRU and the security, integrity and release of the data it holds .

Submissions

The Committee invited written submissions from interested parties on the three questions set out above by  Wednesday 10 February. The deadline has now passed.

______________________

Update March 31, 20101: Is this a surprise?  Contrarians, dissenters and deniers say the report errs.

Update April 5, 2010: A little slower than I had imagined, Watts Up With That denies the accuracy of the report — but the denial is a doozy of denialist argument from authority.  It’s a “guest editorial” by S. Fred Singer. Among other things, Singer’s piece reveals why we don’t let partisan politicians run investigations.  He’s miffed because the investigation didn’t give Singer, nor any other denialist, a chance to malign Hadley CRU.  In listing reasons to put fingers in his ears and not listen, Singer said of the House of Commons report, “It did not take direct testimony from scientifically competent skeptics.” There’s no good reason Commons should have take direct testimony from “scientifically competent skeptics,” it wasn’t a news article where false balance was desired.  Instead, the question was whether Hadley’s scientists had done anything wrong.  Singer can’t know, since he has no direct involvement in Hadley’s work, nor would the biased claims of a denialist be able to shed any more light.  Perhaps critically, Singer can’t know whether the Commons committee took direct testimony from claimed skeptics or not.  That the report doesn’t mention the claims doesn’t mean the question wasn’t raised.   It means that in the end, it wasn’t relevant, and not supported by the facts.

Update April 6, 2010: Singer’s in error.  McIntyre has his say in Appendix 10 of the report.  How many other contrarians, denialists and self-proclaimed “skeptics” are in the report?


Typographical error, a gift to creationists

March 31, 2010

Here’s a post at Ecographica about a typographical error in the Arizona Daily Wildcat, the newspaper of the University of Arizona.

How long before some creationist seizes on it to claim Darwin’s theories are dead?  5 . . 4 . . 3 . . 2 . . .

If you find it, will you note it in comments, please?

(Notice how the only stuff creationists can make hay out of, is error?)

Background

Debates over the evolution of hominin bipedalism, a defining human characteristic, revolve around whether early bipeds walked more like humans, with energetically efficient extended hind limbs, or more like apes with flexed hind limbs. The 3.6 million year old hominin footprints at Laetoli, Tanzania represent the earliest direct evidence of hominin bipedalism. Determining the kinematics of Laetoli hominins will allow us to understand whether selection acted to decrease energy costs of bipedalism by 3.6 Ma.

Methodology/Principal Findings

Using an experimental design, we show that the Laetoli hominins walked with weight transfer most similar to the economical extended limb bipedalism of humans. Humans walked through a sand trackway using both extended limb bipedalism, and more flexed limb bipedalism. Footprint morphology from extended limb trials matches weight distribution patterns found in the Laetoli footprints.

Conclusions

These results provide us with the earliest direct evidence of kinematically human-like bipedalism currently known, and show that extended limb bipedalism evolved long before the appearance of the genus Homo. Since extended-limb bipedalism is more energetically economical than ape-like bipedalism, energy expenditure was likely an important selection pressure on hominin bipeds by 3.6 Ma.

Update:  Wall of Shame

Here are creationists claiming the findings rebut, refute or befuddle Darwin:

Quote of the moment: Charles Darwin and the tangled bank

A tangled bank, near Sandwalk, Darwin's walking path near his home at Downe House - image by GrrlScientist

A tangled bank, near Sandwalk, Darwin’s walking path near his home at Downe House – image by GrrlScientist

The final paragraph of Darwin’s On the Origin of Species By Means of Natural Selection:

It is interesting to contemplate a tangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent upon each other in so complex a manner, have all been produced by laws acting around us. These laws, taken in the largest sense, being Growth with reproduction; Inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less improved forms. Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone circling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.

While thieves and COP15 fiddled, the world’s burning continued . . .

March 18, 2010

A friend wrote me the other day wondering what I thought about the global warming hoax.  I told him I thought denialists and contrarians have acted shamefully claiming that warming is not occurring.

My friend wrote back puzzled.  He had meant, what did I think about the collapse of the false claims of warming?  He said he had understood that almost all the claims of warming were hoaxes cast by a cabal of conspiratorialist scientists who had gotten fat government contracts only on the condition that they claimed there is warming.

It’s actually been about two weeks since I got that message, but it’s a common thought around the world.  The thieves who stole e-mails from scientists did what Shakespeare termed worse: They stole the good names of scientists.  The thieves’ accomplices, especially in blogs but also in brazen journals of bias like The Australian and The Daily Mail, successfully transplanted a stick they claimed was the end of warming science, and they’ve managed to keep it spray-painted green to convince careless observers that it’s alive.

That tree won’t flower.  God’s earth doesn’t care about such falsehoods, but goes on cycling as Darwin noted.  In that cycling, warming continues faster than apace, burning our future and our children’s futures in bits noted only by careful scientists.

While Anthony Watts and other denialists gloated about heavy snows — we’re still cleaning up broken trees and destroyed groves and forests here in Dallas — fact is the North American west suffered from a snow drought.  You may have seen part of it if you watched the Olympics from Vancouver.  It was unseasonably warm, and until the second week there was a great shortage of natural snow for snow events.

We may forget about the ecological chains that weather actually push.  Over at Ralph Maughan’s Wildlife News I found a story about the annual count of elk in Wyoming/Montana/Idaho.  Ralph tracks all sorts of wildlife news, but especially news about wolves and wolf reintroductions.  Wolf packs prey on elk when they can.  The health of elk herds affects the health of wolf packs.

In January I heard there would be no elk count this year because the lack of snow made counting pretty much impossible. I’m glad the amount of snow increased because these numbers are important. Gaps in the data are harmful.

How much have you heard about snowfall shortages in the west, other than the Olympics?  The drought is pretty bad up there.  Much of the Mountain west, on both sides of the Rockies, gets water from the melting snows.  It doesn’t rain much in the spring and summer, but melting snows supply rivers throughout the year.  One reader commented at Maughan’s blog:

I have been in the back country of Montana, Idaho and Washington in the last 3 months and I can tell you, there is no snow to really speak of, the place I stay in Montana normally has about 5-6 feet of snow on the ground in January and when I returned around the first part of January, it had about a foot, Bozeman was very low snow as was Great Falls and Billings, Sandpoint has flowers blooming already, the Columbia River Gorge area up in the Mountains above the Gorge is greening up real well, no snow and Mount Hood has not had much snow either.

Right now, it looks very bleak for river levels this year, My wife was on the phone with her cousin in Florence, MT and Her Uncle in Lincoln, MT this week and they are saying the snow is just not there this year and expects that fishing this year will be very poor due to low water levels and higher river temps, one lives on the Blackfoot and the other on the Bitterroot..

Looks like unless we have a strong spring rain season, things could get dicey this year..

Anecdotal news, just one spot of rather amorphous data, right?

No.  It’s widespread.

Surely not all the droughts nor drought effects can be blamed on warming — but the rolling disasters of dead forests, especially from pine borers and pine bark beetles, across North America, can be fairly attributed to global warming.  Average winters would kill the insects — where average winters now are a rarity, forests that have stood at least since Columbus are dying out.  Many of the dying forests predate the coming of all humans to the Americas, 37,000 years ago or so.

Housing prices will rise.  Wildfires will increase.  Water emergencies will be declared, and restrictions on development in water-strapped counties and states will be enacted.

Humans can deny warming and human causation.  But even the Rockies cry out.

Who will listen?

A carrot for a nose: Healing newtism among climate contrarians

March 18, 2010

Peter Sinclair takes some claims from climate denialists too seriously.  I hope.

On the other hand, he thoroughly shreds some of the more hoary claims of the denialists.  Plus he includes clips of everybody’s favorite movie, Monty Python and the Holy Grail.  Give it a watch, “Flogging the Scientists”:

Gee.  Here in Texas we could use a Peter Sinclair film on history, economics and other social studies.  Quick!
