Annals of global heating, Africa edition: Record heat, again

April 9, 2021


High temperatures in Africa, during the first week of April 2021. MET Office.

Dissenters from the science of global heating/climate change often point to snow in winter, or any cool snap anywhere on Earth in any season, as evidence that global warming cannot occur.

In reality, back on Earth, heat records are being set all over the globe, and there are far more heat records than cold records. (“Global warming” is shorthand for “more energy in the atmosphere,” which means the atmosphere strives for equilibrium by releasing and evening out the energy — and that means storms are more severe, and temperature fluctuations are often more extreme. So we should see record colds, too.)

Britain’s meteorology service, the MET, released the map above last week, showing incredible heat across Africa. Africa is frequently overlooked in discussions about climate change.

Intense hot spell in Subsaharian Africa with Togo getting close to its highest temperature on record (it can attack it tomorrow again). Dapaon with 43.0c sets a new all time high,while Wa in Ghana and Bobo Dioulasso in Burkina Faso both tied their all time Tmax with 42.0C.

Lenticular clouds to drive chemtrails fans nuts – beautiful!

November 16, 2018

Recently found Nuno Serrão via some Twitter posts. He’s an astrophotographer — meaning, a photographer who spends time looking at the skies and works to capture on film or magnetic or digital media the beauty and oddities that hover over our heads every day, and especially at night.

Oh, just look at this time lapse:

Astrophotography timelapse shot in Madeira Island on February 21st [2015]. Captured a lenticular cloud, Moon, Mars and Venus. [33,329 views as of November 16, 2018]

It’s only 7 seconds of video, covering perhaps 15 minutes of time, showing the action of the wind in forming the odd lenticular cloud stunningly painted by a setting sun.

Lenticular clouds don’t resemble the fluffy cumulus clouds of cartoons, and so are held suspect by hoax lovers, especially those enthralled by “chemtrails” hoaxes, who argue that clouds are sinister creations of mad scientists and government cabals. Because this short piece shows some of the actions of winds, I love it more.

True legend has it that an artist friend of physicist Richard Feynman told Feynman that scientists can’t be artists, because they know too much behind the scenes. Feynman answered that scientists have even more appreciation of beauty, the image of the flower and its aroma, and an understanding of the lengthy process by which a plant creates a blossom of beauty and sweet smell, to attract insects or humans to propagate new offspring for the plant.

Is this video science, or art?

Wasatch rainbow timelapse

May 18, 2016

Just your average spring day along the Wasatch Front in north Utah County, in Highland, Utah in Salt Lake County. Time lapse of the old mountains, and the clouds dancing around them as the sun goes down. A hint of the beauty the people of Utah live with every day — and that I hope they don’t take for granted!

It’s great there are so many electronic cameras around these days. A thousand times I’ve watched these things and lamented they couldn’t be captured. Mt. Timpanogos hides just the other side of that first line of mountains; if you know where to look, you can see its hulking shadow.

(When I lived in Utah County, this site was farmers’ fields, from here to the mountains.)

Autumnal equinox, September 23, 2015

September 23, 2015

You can only get this shot on two days each year.

I was sad to discover most of my U.S. history students (juniors) didn’t know what an equinox is. So the autumnal equinox always offers a teaching moment that ticks off the teacher raters.

Summer 2015 ended at 4:15 a.m., September 23.

This is what an equinox looks like, from 2013 photos.

But only twice a year, during an Equinox, can it capture an image like this one, showing an entire hemisphere bathed in sunlight. At an Equinox, the Earth’s axis of rotation is not tilted toward or away from the Sun, so the solar illumination can extend to both the planet’s poles. Of course, this Elektro-L picture was recorded on September 22nd [2013], at the northern hemisphere’s autumnal equinox. For a moment on that date, the Sun was behind the geostationary satellite and a telltale glint of reflected sunlight is seen crossing the equator, at the location on the planet with satellite and sun directly overhead (5MB animated gif).

Wait. Animated .gif?  Cool!

The two satellite images below from the European Meteosat show the sun angle on Earth from June 22 near the summer solstice and then today at the same time.  Notice the sun angle has changed dramatically, and the High Arctic is no longer seeing 24 hour daylight.

Snow Friday

February 27, 2015

It was clear this morning, but the snow started just before 9. It’s predicted to warm up enough that the stuff from the skies will be wet, but the ground will be stay frozen. Ice storm.

Businesses and schools shut down about noon.

Something about snow makes the birds hungry.  A tube feeder we filled last night emptied by noon.

At home we refill the feeders as best we can.

Rewards are high.  We’ve had six species in the yard at any time, all morning, and at least eight species total.

  • Blue jays

    A sparrow -- a chipping sparrow juvenile? -- acting as scout to find food; it was joined by at least two companions after dusting snow off of seeds in the feeder, and finding them suitable.

  • Cardinals
  • Two species of junco
  • House finches
  • Gold finches
  • White-winged doves
  • A sparrow (juvenile chipping sparrow?)
  • Chickadees
  • Wrens (probably Carolina, but they won’t come close to the house)

It would be nice if our downy woodpecker friends would visit, but they’ve been scarce most of the fall.

Where are the titmice?

As usual, we have some vireo or other (Bell’s, I think), but it knows us well enough to be able to sing to get us excited, but appear only when humans are not looking.

How are things in your yard?

We get the goldfinches in winter, with their winter colors; some of the males may be anticipating spring a bit.

Dallas in the fog

December 10, 2014

Enough of the jokes about how nature makes Dallas beautiful by covering everything up.

There were some nice views of Dallas today, with the fog, though.

From WFAA-TV’s tower camera, just before sunrise:

Dallas in the fog, December 9, 2014; photo from WFAA-TV's tower camera.

This photo produced the most stir, I think.  Terry Maxon posted it at his Aviation Blog with the Dallas Morning News:

Maxon wrote:

Maxon wrote: “Mike Alvstad was flying into Dallas/Fort Worth on Tuesday morning and took a photo as his flight from Tampa, Fla., passed south and west of downtown Dallas. He shared it with Lee Evans, who shared it with us, and we liked it a lot.”

Looking for landmarks?  Maxon explained:

In the sea of clouds, you can see the top of Reunion Tower a bit lower to the right. There’s the wedge-topped Fountain Place in the lower center of the downtown cluster. Off to the left by itself is Cityplace, we believe.

Note that even though we could barely see a block ahead of us at ground level, the skyscrapers are casting shadows on the top of the fog clouds.

You want to see what it looked like from the upper floors of those buildings?  Kathryn’s office is below the clouds.  When I worked in the high floors of the old Ling/Temco/Vought Building (now Trammell Crow Tower, I think) we didn’t have cell phones with cameras, and electronic imaging was in its commercialized infancy.  I never had the old 35mm film cameras with me on those few occasions when we rode the elevators up out of the fog, and could almost wave to someone in the tower across the way.  Justin Turveen got off a few shots today, but is being stingy with the photos at his flickr site. Check it out if you wish.

It was foggy across the area starting last night, including Denton, which is home to the University of North Texas and Texas Women’s University:

Mike Prendergrast at Aerial sent his DJI Phantom 2 Vision Plus Drone to work, rising above the clouds, with good results, I think. He had me when I read that he included some time-lapse in there . . .

(Yes, Prendergrast is a great guy, and a good photographer, and he followed the rules and stayed low and out of the way of aircraft.)

Do you have a nice shot of Dallas in the fog to share?  Send it to me, or post it in comments.


Tip of the old scrub brush to Suzy Bangs, who I hope is joining us again this week to take a hot Christmas meal and cheer to the good people at the Pleasant Grove Senior Recreation Center (that’s Pleasant Grove, Texas). Thanks, too, for the splash from Dubious Quality (who is this Gilbert fellow?).

Funny thing is, this photo probably didn’t require much processing to look like this.  Advances in lighting, especially LEDs and color, mean that Dallas’s skyline can look much like this any night.

Just add a thunderhead to the northeast, and voila!

Nota bene: Mr. Higginbotham discovered the photographer to be David Worthington, who is selling prints.  I recommend Dallasites contact him to get one. (Anyone else, too; it’s a great shot.)

Mammatus clouds, Hastings, Nebraska

January 28, 2014

From Twitter today; working to track down more details.

A photo by John C. Olsen, taken in Hastings, Nebraska, perhaps on December 31, 2013:

From Fascinating Pics: One of the rarest weather phenomena, Mammatus Clouds. Photo taken by John C. Olsen in Hastings, NE

From Fascinating Pics: One of the rarest weather phenomena, Mammatus Clouds. Photo taken by John C. Olsen in Hastings, NE

Our boys liked clouds from the start.  A couple of our early cloud identification books featured mammatus clouds (guess where the name came from); and before each boy was 11, we had seen these clouds here in Texas, often in that treacherous time known as tornado season.

Beautiful clouds, yes, but often scary — well, until you read from the University of Illinois that they tend to follow nasty storms, not precede them.

Mammatus Cloudssagging pouch-like structuresMammatus are pouch-like cloud structures and a rare example of clouds in sinking air.

Sometimes very ominous in appearance, mammatus clouds are harmless and do not mean that a tornado is about to form; a commonly held misconception. In fact, mammatus are usually seen after the worst of a thunderstorm has passed.

As updrafts carry precipitation enriched air to the cloud top, upward momentum is lost and the air begins to spread out horizontally, becoming a part of the anvil cloud. Because of its high concentration of precipitation particles (ice crystals and water droplets), the saturated air is heavier than the surrounding air and sinks back towards the earth.

The temperature of the subsiding air increases as it descends. However, since heat energy is required to melt and evaporate the precipitation particles contained within the sinking air, the warming produced by the sinking motion is quickly used up in the evaporation of precipitation particles. If more energy is required for evaporation than is generated by the subsidence, the sinking air will be cooler than its surroundings and will continue to sink downward.

The subsiding air eventually appears below the cloud base as rounded pouch-like structures called mammatus clouds.

Mammatus are long lived if the sinking air contains large drops and snow crystals since larger particles require greater amounts of energy for evaporation to occur. Over time, the cloud droplets do eventually evaporate and the mammatus dissolve.

Our experience is the clouds look a lot cooler than can be captured on film or in electronic images.  Mr. Olsen captured a great image.

Very nice shot

Just point your cameras to the skies and shoot: Lubbock on August 14

August 14, 2013

With all the cameras around, if everybody just points their own camera to the skies and starts shooting, we’ll get some good shots.

Tonight the Texas Storm Chasers sent this one out:

Looks like “Night on Storm Prairie” to me. (Where’s Disney when you need em?)

Shot with a camera phone, I’m guessing from inside a hotel (are those reflections in the window?).  Not sure who shot it, so I’ve just credited “Texas Storm Chasers.”

Weather is cool.  Photos of weather are cool, too.

Sky that makes people repent

Tornado Titans comment at Facebook:

“Main Street Buffalo” – Looking down Main Street of Buffalo, Oklahoma as a severe thunderstorm dumping large hail sits nearly stationary just north of town. I’ve been wanting to get a scene like this for a long time. This was still in the late afternoon and it looked like evening outside, the locals were wondering why I’d keep running out in the middle of the road in between traffic with my camera one guy stopped to ask us if we were broke down. Great people!

You see a few of these skies in a week, you’re not so anxious to stand outside and deny global warming caused by humans.  With luck, enough people will be driven to repent of their denialism, and we can get some serious action to restore the atmosphere.


What does Superstorm Sandy tell us about how to vote? Is disaster aid “immoral?”

October 29, 2012

Is it immoral for the federal government to coordinate disaster responses, and to provide aid for disasters, especially during and after superstorms like Sandy?

SUOMI view of Hurricane Sandy, early October 29, 2012 - NASA image

Caption from NASA: This night-view image of Hurricane Sandy was acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite around 2:42 a.m. Eastern Daylight Time (06:42 Universal Time) on October 28, 2012. In this case, the cloud tops were lit by the nearly full Moon (full occurs on October 29). Some city lights in Florida and Georgia are also visible amid the clouds.

I was troubled when GOP Louisiana Gov. Bobby Jindal called for cuts to disaster forecasting and especially our volcano monitoring systems, in 2009. I’ve been troubled by slams at NASA and NOAA with calls to cut budgets for orbiting satellites used to forecast storms and floods and other disasters, from the GOP.

And, with Sandy bearing down on the U.S. Northeast, Middle Atlantic and New England states (where older son Kenny lives in building that is, we hope, about 20 feet above sea level), I’ve been troubled by memories of calls for cuts to FEMA in the Republican presidential primaries.

Correspondent James Kessler tracked down a transcript from a campaign event in June, a presidential candidate cavalcade broadcast by CNN, with John King as moderator/anchor.  Look at this exchange:

KING: What else, Governor Romney? You’ve been a chief executive of a state. I was just in Joplin, Missouri. I’ve been in Mississippi and Louisiana and Tennessee and other communities dealing with whether it’s the tornadoes, the flooding, and worse. FEMA is about to run out of money, and there are some people who say do it on a case-by-case basis and some people who say, you know, maybe we’re learning a lesson here that the states should take on more of this role. How do you deal with something like that?

ROMNEY: Absolutely. Every time you have an occasion to take something from the federal government and send it back to the states, that’s the right direction. And if you can go even further and send it back to the private sector, that’s even better.

Instead of thinking in the federal budget, what we should cut — we should ask ourselves the opposite question. What should we keep? We should take all of what we’re doing at the federal level and say, what are the things we’re doing that we don’t have to do? And those things we’ve got to stop doing, because we’re borrowing $1.6 trillion more this year than we’re taking in. We cannot…

KING: Including disaster relief, though?

ROMNEY: We cannot — we cannot afford to do those things without jeopardizing the future for our kids. It is simply immoral, in my view, for us to continue to rack up larger and larger debts and pass them on to our kids, knowing full well that we’ll all be dead and gone before it’s paid off. It makes no sense at all.

Can you imagine how different the world would be today had Americans shared that view in 1936, or 1940, or 1942?  Immoral to do what is necessary to preserve the future, because we have to borrow to do some of it?

Has Romney changed his position in the last 24 hours?  I predict he will change it very soon, if he hasn’t already flip-flopped on it.  Of course, he may double down on crazy, and stand pat.   What do you think a rational patriot would do in this case?  [At about 1:00 p.m. Central Time, I heard an NPR radio news report — Romney urges private contributions to the Red Cross.  Meanwhile, President Obama has been working all morning to make sure the disaster response from the federal government is coordinated with affected states.] [Ha! But within hours, Romney has taken the almost-opposite position again.  World land speed record for flips on an issue?]

I erred, perhaps.  I had thought Mitt Romney the most capable and sober of the GOP candidates for president, and I urged by GOP friends to support Romney if they had no chance of completely recovering their senses by November.  Now I realize that, on the GOP side, “most capable” should be “most nearly capable,” and still means “incapable.”  And “sober” means nothing at all.  Perhaps worse, he’s still the best of the GOP lot this year.  Even worse, he has a chance to win.

Can we blame Romney?  Yes, we can blame people who reject science and don’t think of consequences past election day.  Yesterday Greg Laden offered a long post on what we should have learned from the “Storm of 1938” and the remnants of Hurricane Irene that slammed the Northeast in 2011, “What you need to know about Frankenstorm Hurricane Sandy”:

Here’s the thing. Imagine that a storm like Sandy came along in either of two years; 70 years ago or 35 years ago. Sandy is much larger and contains much more energy than the ’38 storm, or for that matter, of any known storm of the North Atlantic (we’ll get to that below). If Sandy hit the region in the 1930s, it would have been without warning, and it would have been prior to the reconstruction of seawalls and the development of flood mitigation measures inland that have happened in recent decades. Sandy, in ’38, would kill tens of thousands and destroy thousands of structures. That would be an average Sandy, a Sandy not being as bad as the most dire predictions we are considering today as the storm begins to take a grip on the eastern seaboard.

A Sandy of 35 years ago would have been predicted. The ability to see hurricanes coming was in place, but not as well developed as it is today. We would have seen Sandy coming, but her massiveness and extent, and her exact trajectory, would probably have been unknown. But at least there would be warning. Many of the seawalls and flood mitigation systems would have been in place, but the overbuilding on barrier islands and other vulnerable coastal regions would have been at or near a peak. With evacuations, Sandy would not kill 10s of thousands… probably only hundreds. But the number of buildings destroyed would be unthinkable. Most of those buildings are now gone or shored up. A Sandy in 1975 would have left some very interesting coastal archaeology for me to have observed during my trips to the shore in the 1980s. Very interesting indeed.

Mr. Laden always offers a good view of science, and his history is good here, too.

We can learn from the past.  FEMA is charged with learning from past disasters.  It’s a function of federal government we would be foolish to forego.  “Austere” shouldn’t mean “stupid.”

What do you think?  Is it immoral for the federal government to provide disaster assistance?


Blame global warming for wild weather? NASA says, “Blame La Nada”

June 27, 2011

Here’s what NASA said:

What’s to Blame for Wild Weather? “La Nada”

Such sheets of fire, such bursts of horrid thunder,
Such groans of roaring wind and rain, I never
Remember to have heard; man’s nature cannot carry
The affliction nor the fear
… from Shakespeare’s Tragedy of King Lear

June 21, 2011: Record snowfall, killer tornadoes, devastating floods: There’s no doubt about it. Since Dec. 2010, the weather in the USA has been positively wild. But why?

Some recent news reports have attributed the phenomenon to an extreme “La Niña,” a band of cold water stretching across the Pacific Ocean with global repercussions for climate and weather. But NASA climatologist Bill Patzert names a different suspect: “La Nada.”

“La Niña was strong in December,” he says. “But back in January it pulled a disappearing act and left us with nothing – La Nada – to constrain the jet stream. Like an unruly teenager, the jet stream took advantage of the newfound freedom–and the results were disastrous.”

Wild Weather (La Nina, 558px)

The blue and purple band in this satellite image of the Pacific Ocean traces the cool waters of the La Niña phenomenon in December 2010. (from Ocean Surface Topography Mission (OSTM)/Jason-2 satellite, Credit: NASA JPL)

La Niña and El Niño are opposite extremes of a great Pacific oscillation. Every 2 to 7 years, surface waters across the equatorial Pacific warm up (El Niño) and then they cool down again (La Niña). Each condition has its own distinct effects on weather.

The winter of 2010 began with La Niña conditions taking hold. A “normal” La Niña would have pushed the jet stream northward, pushing cold arctic air (one of the ingredients of severe weather) away from the lower US. But this La Niña petered out quickly, and no El Niño rose up to replace it. The jet stream was free to misbehave.

“By mid-January 2011, La Niña weakened rapidly and by mid-February it was ‘adios La Niña,’ allowing the jet stream to meander wildly around the US. Consequently the weather pattern became dominated by strong outbreaks of frigid polar air, producing blizzards across the West, Upper Midwest, and northeast US.”1

The situation lingered into spring — and things got ugly. Russell Schneider, Director of the NOAA-NWS Storm Prediction Center, explains:

“First, very strong winds out of the south carrying warm, moist air from the Gulf of Mexico met cold jet stream winds racing in from the west. Stacking these two air masses on top of each other created the degree of instability that fuels intense thunderstorms.”

Extreme contrasts in wind speeds and directions of the upper and lower atmosphere transformed ordinary thunderstorms into long-lived rotating supercells capable of producing violent tornadoes.2

Wild Weather (La Nada, 558px)

This satellite image, taken in April 2011, reveals La Niña’s rapid exit from the equator near the US coast. The cool (false-color blue) water was gone by early spring. (from Ocean Surface Topography Mission (OSTM)/Jason-2 satellite, Credit: NASA JPL)

In Patzert’s words, “The jet stream — on steroids — acted as an atmospheric mix master, causing tornadoes to explode across Dixie and Tornado Alleys, and even into Massachusetts.”

All this because of a flaky La Niña?

“La Niña and El Niño affect the atmosphere’s energy balance because they determine the location of warm water in the Pacific, and that in turn determines where huge clusters of tropical thunderstorms form,” explains Schneider. “These storms are the main energy source from the tropics influencing the large scale pattern of the jet stream that flows through the US.”

In agreement with Patzert, he notes that the very strong and active jet stream across the lower US in April “may have been related to the weakening La Niña conditions observed over the tropical Pacific.”

And of course there’s this million dollar question: “Does any research point to climate change as a cause of this wild weather?”

“Global warming is certainly happening,” asserts Patzert, “but we can’t discount global warming or blame it for the 2011 tornado season. We just don’t know … Yet.”3

What will happen next? And please don’t say, “La Nada.”

End Notes

(1) Other atmospheric factors also contributed to the inflow of frigid polar air, says Patzert. One of the most significant was a weakening in the whirlpool motion of the air around the North Pole. As a result of this weakening, more cold air flowed away from the pole and down toward the states. Climatologists call this an “arctic oscillation.”

(2) Imagine a paddle wheel oriented like a Ferris wheel and placed in winds that that are much stronger at the top than at the bottom. The wheel will spin in the direction of the strong winds above. This spring, these strong, turning winds led to ongoing rotation of the supercells themselves. So we ended up with intense rotation and updraft close to Earth’s surface — conditions ripe for strong tornadoes.

(3) On May 26, 2011, Patzert posted a comment about this topic on Andrew Revkin’s The New York Times’ DOT EARTH Blog, “Demography, Design, Atom Bombs and Tornado Deaths.” See comment 6 at this URL.

Looks to me as if the people at NASA are saying we should go slow, and not rush to blame our weather woes on climate change. Climate change “skeptics” should be so skeptical.

Students frozen out of schools, education, maybe hope

February 9, 2011

Does the headline pertain to Dallas ISD’s being closed for cold weather for the fifth day in eight, or does it refer to the situations in Austin, where Gov. Rick Perry insists Texas is better off than the rest of the nation with a $25 billion deficit it can’t close, and all education institutions being given solitary confinement or death penalties?

Ironic: Super Bowl host cities shut down by ice

February 1, 2011

280 sanding trucks patrol the streets of Dallas County, but the thin sheet of ice closed us down.  Dallas ISD did the right thing — and it turns out that DISD’s closing for weather is so rare that every other institution we work with keys off of them, knowing that means fewer shutdowns.  But today, ice, no dice.

Dallas ice, January 2009 - photo by Lauren Allen

Sorta like this 2009 photo of north Dallas, but without the pretty sky, with duller ice, and more cold. Lauren Allen is a professional photographer -- did she add in the nice sunrise? (Buy the photo and see!) It doesn't look so treacherous as it is; not seen in the photo: an estimated (by me) 24 jackknifed 18-wheelers on I-635, just a few blocks away.

So, five days to Super Bowl, and Green Bay and Chicago Pittsburgh fans can’t fly to Dallas because of ice.  I imagine fans already here a jumping up and down in their $500-a-night hotel rooms, incredulous that such a thin sheet of cold stuff is keeping them holed up like naked mole rats.  Host city events in Fort Worth and Dallas are cancelled for today, and maybe for much of the rest of the week.

Son James, at Lawrence University in Appleton, Wisconsin, is just three degrees colder, but missing the ice and wind we have.  His windchill isn’t so great as ours.  Windy City, you ain’t seen nothing like the winds of Texas.  Usually they don’t blow so cold, though.

Our front gate is frozen.  The lock won’t budge.  We’ll have to snowshoe from the backyard to get the newspaper.

Global warming deniers are dancing with glee.  They think the fact that we’ve got Arctic weather means warming isn’t happening, forgetting to look to the Arctic, which is eerily warm.

But it’s all cool.  No school!
