Denialists are Doomed

It’s been a frigid winter in much of the United States, but Greg Laden notes that the country covers only 1.5% of the Earth’s surface, and overall the planet just experienced the fourth-warmest January on record.  Meanwhile global warming denialists are resorting to every rhetorical trick in the book, such as comparing their increasingly outnumbered…

Hot Winter Days

The anti-scientific M.O. of some political conservatives was in full swing during the ‘polar vortex,’ as frigid weather brought south from the Arctic led many commentators to scoff, “look how cold it is, can you believe anyone thinks the Earth is getting warmer?” Coby Beck adds some perspective from climate historian Christopher C. Burt on…

The fifth assessment report of the Intergovernmental Panel on Climate Change was released last week, saying that global warming is occurring without a doubt, and human activity is extremely likely to be the cause.  Greg Laden shares a number of graphics from the report, summarizing “It is getting hotter. It is getting wetter, or dryer,…

Life has been growing on Earth for about 4 billion years, and during that time there have been a handful of mass extinctions that have wiped out a large percentage of complex lifeforms.  Asteroid impact, volcanic eruption, climate change, anoxia, and poison have dispatched untold numbers of once-successful species to total oblivion or a few…

When the controversial and talented physicist Edward Teller was doing a PhD. with the great Werner Heisenberg at the University of Leipzig, the question asked at the end of every group meeting that focused on a complex sequence of problems was “Wo ist der Witz?”, supposed to be translated as “What is the point”? but…

In an article in The New York Times Magazine Sunday, Freeman Dyson—best known for his work in theoretical physics—discussed his belief that climate change is an issue that should be approached with skepticism. ScienceBloggers responded with thoughtful consideration. Dyson stated in the Times piece that while prevailing dogmas about climate change may be right, they…

The potential for various geo-engineering proposals to offset the effects of climate change is often not factored in to near- and long-term climate scenarios. In a study conducted by NOAA, released this week, the authors predicted “irreversible changes,” but noted, “we do not consider geo-engineering measures that might be able to remove gases already in…
