I suspect most of these global warming alarmists, including President Obama's science advisers, know they are wrong but continue the myth of man-caused global warming for reasons other than the "health of Mother Earth". Oh, and now they want to change the terminology from "global warming" or "climate change" to "climate disruption". Isn't that clever? The only problem is I think people are tired of being fooled, manipulated, and lied to. I'm very happy to see an article like that which follows, published in that icon of the mainstream media, "Newsweek Magazine". As I have been saying on this blog since the beginning, the myth of man-caused global warming will be destroyed. The truth will prevail.
I propose our teachers teach real Earth History as a contrast to Al Gore's fatalistic fantasies.
The Earth Doesn’t Care
About what is done to or for it.
For example: The world’s total precipitation in a year is about one meter—“the height of a golden retriever.” About 200 meters—the height of the Hoover Dam—have fallen on earth since the Industrial Revolution. Since the Ice Age ended, enough rain has fallen to fill all the oceans four times; since the dinosaurs died, rainfall has been sufficient to fill the oceans 20,000 times. Yet the amount of water on earth probably hasn’t changed significantly over geologic time.
Damaging this old earth is, Laughlin says, “easier to imagine than it is to accomplish.” There have been mass volcanic explosions, meteor impacts, “and all manner of other abuses greater than anything people could inflict, and it’s still here. It’s a survivor.”
Laughlin acknowledges that “a lot of responsible people” are worried about atmospheric concentrations of carbon dioxide from burning fossil fuels. This has, he says, “the potential” to modify the weather by raising average temperatures several degrees centigrade and that governments have taken “significant, although ineffective,” steps to slow the warming. “On the scales of time relevant to itself, the earth doesn’t care about any of these governments or their legislation.”
It seems, Laughlin says, that “something, presumably a geologic regulatory process, fixed the world’s carbon dioxide levels before humans arrived” with their SUVs and computers. Some scientists argue that “the photosynthetic machinery of plants seems optimized” to certain carbon dioxide levels. But “most models, even pessimistic ones,” envision “a thousand-year carbon dioxide pulse followed by glacially slow decay back to the pre-civilization situation.”
Laughlin believes that humans can “do damage persisting for geologic time” by “biodiversity loss”—extinctions that are, unlike carbon dioxide excesses, permanent. The earth did not reverse the extinction of the dinosaurs. Today extinctions result mostly from human population pressures—habitat destruction, pesticides, etc.—but “slowing man-made extinctions in a meaningful way would require drastically reducing the world’s human population.” Which will not happen.
Climate change over geologic time is, Laughlin says, something the earth has done “on its own without asking anyone’s permission or explaining itself.” People can cause climate change, but major glacial episodes have occurred “at regular intervals of 100,000 years,” always “a slow, steady cooling followed by abrupt warming back to conditions similar to today’s.”
Six million years ago the Mediterranean dried up. Ninety million years ago there were alligators in the Arctic. Three hundred million years ago Northern Europe was a desert and coal formed in Antarctica. “One thing we know for sure,” Laughlin says about these convulsions, “is that people weren’t involved.”
