Warming to Climate Claims

As Washington D.C. gets record snowfall, climate denialists cackle with glee. It was a cool summer, and now a cold winter. So, they wonder, where is this global warming? "People," I want to condescendingly say, "look at the sun." Weather girls of all genders and persuasions are mentioning that this is the coldest winter in 11 years. Notice that? Are they unaware that there is an 11 year cycle of solar warming and cooling that corresponds to -- and can be measured by -- sunspots? So it's like saying with implied importance that this is the coldest month since 12 months ago. The spots are just starting up, much like the days getting longer at the end of December. Here is a nice look at the sunspot phenomenon. It is intuitively confusing that dark spots mean more heat. But the pair of images here shows visible and ultraviolet views of the same scene. Those dark spots are tunnels into the gamma-hot regions of the sun. Our eyes can only see one octave on the spectrum. Both hotter than blue and cooler than red ranges are invisible. Dark. Red hot is the coldest temperature that gives off light. (Read about Black Body Radiation if you want to know how this is known.) Another detail that climate denialists get wrong is the meaning of heavy snowfall. If you get heavy precipitation, it implies much moisture aloft. That is, many more megatons of water are evaporated. By heat. So before you point to a low local current temperature as evidence against global warming, please look at the time scale that climatologists use, like the Temperature record of the past 1000 years, or even for the last century and a half:

Changing our approach in our classrooms

In her NYT Op-Ed, Pychologist Susan Engel advises what we are doing wrong in the classroom. She argues that we need to do more than change the way we measure progress--we need to overhaul the entire way we teach:

In order to design a curriculum that teaches what truly matters, educators should remember a basic precept of modern developmental science: developmental precursors don’t always resemble the skill to which they are leading. For example, saying the alphabet does not particularly help children learn to read. But having extended and complex conversations during toddlerhood does. Simply put, what children need to do in elementary school is not to cram for high school or college, but to develop ways of thinking and behaving that will lead to valuable knowledge and skills later on. . . . What they shouldn’t do is spend tedious hours learning isolated mathematical formulas or memorizing sheets of science facts that are unlikely to matter much in the long run. Scientists know that children learn best by putting experiences together in new ways. They construct knowledge; they don’t swallow it.

Temple of Disinformation

In America's heartland there is a modern temple to the denial of five nines (99.999%) of what we've learned about the universe in the last couple of centuries. The Creation Museum is a sleek, elegant, well presented indoor theme park almost entirely lacking in actual knowledge. It is derided worldwide, and is a source of shame for our once forward thinking nation. It is also, I grant, an edifice to the principle of free speech. The ham, showman and charlatan who created this institution in Kentucky after he was laughed out of his Australian homeland seems to be quite sincere about the project. Ken Ham is actually his name. And he has been raking in major profits for nearly three years from this place, well beyond even his early hopes. Apparently there is more than one born again every minute. Busloads of young Christians long to go on pilgrimages to shore up their Young Earth ideology. The younger ones (under 12) can even get their picture taken on the back of a dinosaur, just like those that people rode. That is, before the old west cowboys killed the last of them off. That's why all those T-Rexes are found out on the great plains. You don't have to take this from me on faith, follow the links from the Wikipedia article on the Creation Museum. See actual video tours. So, why am I venting my bile right now? Wasn't this already adequately covered on this site? I just learned that a young collateral relative, a bright young man, is looking forward to his trip there this weekend! Half a dozen years ago, he was in public schools, in every advanced program they offered. Advanced science and math and lead cello in the district orchestra. Then his parents removed him from all that intellectual wealth to put him in a small Christian school. He still excelled, eventually garnering college board scores that got him invitations to Harvard and Yale and such. But he wants to go to a small school with an influential chapter of the Campus Crusade. Sigh. Most of this is re-posted from this FaceBook note.

The type of damage caused by media violence

Media Education Foundation has released a new video: The Mean World. This documentary studies the work of communications scholar George Gerbner, who carefully studied media violence for four decades. What is the effect of media violence? It doesn't seem to make most of those who watch it engage in violent acts. Rather, viewing repeated acts of violence is "likely to make us more scared of violence being done to us." Gerbner's team repeatedly determined that "commercial media have eclipsed religion, art, oral traditions, and the family as the great story-telling engine of our time." As Gerbner noted, a small handful of commercial conglomerates have global marketing formula that are imposed on the people in Hollywood [who are told] put in more action. Cut out complicated solutions. Apply this formula because it travels well in the global market. These are formulas that need no translation, that are image-driven, that speak action in any language . . . and the leading element of this formula is violence." This tidal wave of highly choreographed violence is unprecedented, and it is being pumped into every home. Most children now see 8,000 murders by the end of elementary school. Gerber holds that this violence is so dangerous because it has become routine.
