Richard Kerr has an excellent article in today’s Science ((Pushing the Scary Side of Global Warming, Science 8 June 2007: 1412-1415, sub. req.)) looking at the discomfort scientists face in going beyond the IPCC’s conclusions on the extent to which sea level might rise over the next century. The problem here is how to approach …
James Hansen and company have a new paper attempting to define “dangerous climate interference” and suggest where we currently stand relative to their chosen standard. Their answer? Close: We examine potential criteria for dangerous climate change assuming that humanity wants to preserve planetary conditions similar to those in the period of civilization, thus near the …

The minnow release was a celebration of efforts to save the fish from extinction. The mosquitoes were a reminder of an especially wet spring— nature cooperating with …
New NASA data shows accelerated snowmelt in Greenland: To understand why these trends are important to track, Tedesco explained one of the consequences of melting snow. “Although wet and dry snow look similar at first glance, wet and re-frozen snow absorb more of the sun’s radiation, reflecting only 50-60 percent back into the atmosphere. Dry …

In that regard, this data from Google’s new search terms trends monitoring tool: This is the relative use by people searching on Google of the terms “global warming” (blue line) and “climate change” (red …
Brad Udall at the Western Water Assessment has written an extremely helpful summary of the history of research into the effects of climate change on the Colorado River. It is interesting to note a consistent message in nearly 30 years of work on this question: the sign is nearly always negative. There’s not a whole …
Roger Pielke Sr. and I have been having a polite disagreement today over at his blog on how to think about Richard Seager’s paper last month in Science on the risk of future drought in the southwest. Roger argues Seager’s work is contradicted by a 1997 paper by Trenberth and Hoar arguing for stronger El …
