Climate Change Denialism Spreading in US Public Education Related Proposals

Spread the love

It is no longer the case that science teachers and concerned parents only need to worry about creationists invading US classrooms, via personal intrusion (by parents, students, or creationist teachers) or by legislation or regulation. Increasingly climate change denialism is being shoved into science classes by the usual nefarious forces.

This is not really new. “Academic Freedom” bills in many states over the last decade or so were introduced to try to force college professors to shut up about climate change. In the college setting, I’ve had about the same level of resistance to global warming as to evolution, if not more. But as Neela Banerjee points out, we may be nearing a flash point in American science education:

Russian Rivers and Arctic Salinity: Climate Variation Better Understood

Spread the love

This post was chosen as an Editor's Selection for ResearchBlogging.orgThe sun heats the earth, but unevenly. The excess heat around the equator moves towards the poles, via a number of different mechanisms, the most noticeable for us humans being via air masses. That’s what much of our weather is about. Heat also moves towards the poles, in the ongoing evening-out of energy distribution on the planet’s surface, via ocean currents.

One of the interesting things that happens with ocean currents is this: Warm water tends to move from equator towards polar regions across the surface, then cools down and drops to the deep sea, where it moves back south again, often in a kind of loop that we call a "conveyor." Becuase of some quirky historical stuff, the continents on this planet are mostly in the norther hemisphere, so the loops of ocean water that mariners have long called "currents" are extra strange in the north, and as it happens, there is a big loop of warm water or two that go way farther north (as warm water) than usual, where increased evaporation and cooling cause the water to a) loose it’s heat to the air and b) sink rather dramatically to the bottom of the sea. The sinking helps direct the north-moving surface currents, maintaining the loop. The release of heat keeps England from looking like Canada and Norway from looking like Greenland, as much of this heat leaves the North Atlantic and traverses Europe first. By the time that energy gets around the world all the way back to Greenland, well, it isn’t helping to melt glaciers very much, bit it does in fact have an effect. Without this warming, there would probably be continental glacial masses on Europe and Canada, rather than scattered and small mountain glaciers. In other words, there would be an ice age.

Did I mention the evaporation as a driving force in the conveyor? Yes, of course I did. And the reason this works is that when the warm surface water evaporates, it becomes more saline relative to the rest of the ocean, and sinks, because salty water is denser than fresh water. We believe that there have been times in the past when fresh water being added to the northern seas has mixed with a conveyor, caused the water to be less salty, turned off the flow of warm water to the northerly latitudes, and ushered in a mini-ice age, or perhaps a maxi-ice age. Indeed, there are some theories about paleoclimate that suggest, very strongly, that this is exactly the mechanism that triggers an ice age.

All Candidates Should Acknowledge Climate Change

Spread the love

Obviously! But they mostly don’t. Check this out:

New Hampshire scientists call on “all candidates” to “acknowledge” cliamte change

In 2008, one of the little acknowledged political subtexts was how significantly global warming played in the Republican primary process. Both independently and as part of organizational efforts, individuals asked questions at events (and on street corners) and many events has signs about voters’ concerns over the need for climate change action. John McCain stood alone in discussing climate change forthrightly. In terms of impact, John McCain might just have won in New Hampshire (setting him on the path for the nomination) due to statements like these:

Would you like some tea with your climate change?

Spread the love

One of the authors of Ice Ages: Solving the Mystery (John) himself, Shackleton himself, and Emiliani himself were ushered into the building past the graduate students, the guards, and the members of the public who wandered the halls of the museum blissfully unaware that the powerhouses of paleoclimate research were brushing past them. They were Glynn Isaac’s guests (and friends and colleagues) and were meeting with Glynn in preparation for an impromptu public conference that would be held the next day in the Geology Lecture Hall downstairs. These were the people who had put the climatic theory of Milutin Milankovic together with the sea core data and nailed down, once and for all, the cause of the basic mode and tempo of Earth climate for the last two or three million years, and at some level, certainly, for all time.

Atheist Talk This Sunday: Climate Change and Science Denialism

Spread the love

This week on Atheist Talk Radio, I’ll be interviewing Shawn Lawrence Otto, who has just launched his book, “Fool Me Twice: Fighting the Assault on Science in America,” a richly documented and well reasoned analysis of modern science denialism, especially addressing climate change.

We’ll speak about Shawn’s book as well as the current state of climate change research and the related politics. I guarantee a lively and enlightening conversation.

If you are in the Twin Cities, please, join us at Q. Cumbers for brunch. If you bring a copy of Shawn’s book and a pen you can get it signed!

We would also like to note that this Sunday’s Q. Cumbers brunch will be also be a meet-up of a different kind. There will be at least three FTB.com (Free Thought Blogs) bloggers at the brunch, Stephanie (who is also hosting the radio show), Moi, and coming down from Canada with his wife Jodi, will be Jason.

There is a question about climate change from a gentleman in the fourth row.

Spread the love

He introduces himself as Richard Rothschild. He tells the crowd that he ran for county commissioner in Maryland’s Carroll County because he had come to the conclusion that policies to combat global warming were actually “an attack on middle-class American capitalism.” His question for the panelists, gathered in a Washington, DC, Marriott Hotel in late June, is this: “To what extent is this entire movement simply a green Trojan horse, whose belly is full with red Marxist socioeconomic doctrine?”

Here at the Heartland Institute’s Sixth International Conference on Climate Change, the premier gathering for those dedicated to denying the overwhelming scientific consensus that human activity is warming the planet, this qualifies as a rhetorical question….

An Open Letter to Climate Change Deniers

Spread the love

Check it out:

OK, you have fought hard to deny or challenge the realities of climate change, perhaps because you are afraid of the policies that might have to be put in place; or are afraid of the possibilities of increased government intervention; or you don’t think it will be that bad; or you think it will be too expensive to do anything about; or you don’t understand the science; or you don’t trust scientists, including, by the way, every national academy of sciences and every professional scientific organization in the geosciences… or whatever.

What do Donald Prothero, Dinosaurs, Climate Change and Bigfoot have in common?

Spread the love

I’m very excited to have the opportunity to interview Don Prothero this coming Sunday on Atheist Talk Radio. If you are local to the Twin Cities, you can listen in on AM 950. If not, you can get there via the Minnesota Atheist web site (where you will have to pretend you live in a twin cities zip code, such as 55433). Also, AM 950 is available on at least one digital radio station server … I seem to be able to get it on my Roku.

Prothero is a palaentologist who has been featured on the Discovery Institute web site (they don’t like him) as well as several podcasts (see below). He is a prolific writer and has produced numerous books, some widely known and some much more esoteric but among my favorites (I happen to be in to the evolution of Artiodactyls, as are most people who study human evolution).

The number of things Don and I can potentially talk about is huge, but among them will be a few questions I’ve been saving up for him regarding climate change vis-a-vis Polar Dinosaurs, the melting of the Ice Caps, inter-species competition and macroevolution, and of course the magnetostratigraphy of the Eocene-Oligocene boundary. We will also speak, perhaps extensively, of his new writing project which involved another one of my favorite subjects, cryptozoology.

Don is in town for the Geological Society of America meetings, and he is also going to give a talk for Minnesota Atheists on Sunday afternoon (Details here.). I know some of you are going to ask me: Are we going to Q-Cumbers after the radio show? I don’t know. Hopefully we will know before the show starts and if we are, hopefully somebody will remember to mention it. So listen in!

Professor Prothero is Professor of Geology at Occidental College and Lecturer in Geobiology at the California Institute of Technology. He is a Fellow of the Geological Society of America and the Paleontological Society.
