Freeman Dyson, global warming, ESP and the fun of being “bunkrapt”

Should a scientist who believes in extrasensory perception—the ability to read minds, intuit the future and so on—be taken seriously? This question comes to mind when I ponder the iconoclastic physicist Freeman Dyson, whom the journalist Kenneth Brower recently profiled in The Atlantic‘s December issue. "The Danger of Cosmic Genius" explores Dyson’s denial that global [...]

“Neuroframing” the global warming issue won’t win converts

Last week the Garrison Institute, a retreat center just a few miles down the Hudson River from my home, hosted an impressive symposium on “Climate, Mind and Behavior.” An organizer made the mistake of inviting me to the meeting’s wrap-up session Friday. As a brochure put it, the symposium brought together 75 “thought leaders and [...]

World Cup Picks Endangered Armadillo as 2014 Mascot

World Cup 2014 mascot

The Brazilian three-banded armadillo (Tolypeutes tricinctus) can roll itself into a ball so tight that only a puma’s claws can penetrate its protective shell. But this evolutionary advantage hasn’t done much to protect the species from humans, who have turned savannah habitats into inhospitable cattle ranches and soybean plantations. Once found throughout Brazil, the armadillos—one [...]

Platypus Populations on Small Australian Islands Show Lack of Genetic Diversity, High Risk of Disease

Last year we learned that climate change could soon make Australia too hot for the cold-loving, iconic platypus (Ornithorhynchus anatinus). Now we have word of a new threat to these unique, egg-laying mammals: inbreeding, which has put the platypuses living on two small Australian islands at enhanced risk of disease. According to research published March [...]

Numerous other species in Guatemala and Mexico also failed to turn up during several surveys [...]

Humans Bring On Many Changes, Most Are Far From Painless

What happens in Vegas apparently spreads from Vegas....

Who Is Fooling Whom When It Comes to Combating Climate Change?

obama-and-xi

Here’s the scam. A Chinese company manufactures hydrofluorocarbons, the refrigerant gases partially responsible for the ozone hole and climate change. The gases can efficiently be turned into cash, either by using them in products like refrigerators or air conditioners or, more lucratively, by destroying them. In the early part of the last decade, Chinese manufacturers [...]

Climate Paradox: Longer Antarctic Melt Season May Mean Less Global Warming

Glacier ice shelves breaking up in the Antarctic

Normally, the news that Antarctica’s summer melt season is getting longer might just be added to an endless compilation of scientific evidence that confirms the reality of global climate change. A recent research report, though, seems to run counter to the conventional wisdom. It shows that if the ice pack at the bottom of the [...]
