Green Analysts Respond to Cross-Check Concerns about Warming, War and Hawkish U.S. Policies

Photo: Meditate.com, http://www.mediate.com/mobile/article.cfm?id=5042.

For a professional blowhard, there is no worse fate than being ignored. So I’m always—well, almost always—delighted when my posts get pushback, especially from people who are smart, well-informed and thoughtful. In my last post, “Hawkish U.S. Policies Pose Bigger Threat to Peace Than Climate Change,” I complained that discussions of how global warming might [...]

Hawkish U.S. Policies Pose Bigger Threat to Peace Than Climate Change

Hawkish U.S. policies are far more of a threat to world peace than global warming, if recent history is any guide.

In a previous post, I poked my nose into the debate over whether climate change will precipitate more conflict. I offered a half dozen objections to predictions that more warming means more war. One objection was that “many people making decisions that lead to large-scale violence—politicians, generals, warlords, drug kingpins and so on—work indoors in [...]

Greens Should Stop Claiming More Warming Means More War

War deaths have plummeted since 1950, according to data compiled by the Peace Research Institute Oslo (PRIO)...

“There’s a surprisingly strong link between climate change and violence.” That’s the headline of a recent article by journalist Chris Mooney in The Washington Post. As fossil-fuel emissions push temperatures higher, we can “expect more wars, civil unrest, and strife, and also more violent crime in general,” Mooney says. But the evidence for this alarming [...]

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

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 [...]

Americans Who Mistrust Climate Scientists Take Cues from Global Temperatures
