September 8th, 2008A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants.
September 4th, 2008Despite projections by some scientists of global seas rising by 20 feet or more by the end of this century as a result of warming, a new University of Colorado at Boulder study concludes that global sea rise of much more than 6 feet is a near physical impossibility.
July 29th, 2008Discussion of Andy Revkin's article in the Science Times on the problem of journalistic coverage of new findings vs. what is widely agreed upon in climate change science.
July 29th, 2008Tad Pfeffer was interviewed by Andrew Revkin (New York Times) for an article about how reporting of discordant findings in climate science are leaving many readers with "whiplash" from alternating "yes it is" and "no it isn't" messages. Such whiplash may fuel the mistaken notion that scientists can't agree on basic well-studied questions.
June 19th, 2008Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation.
May 20th, 2008A variety of factors was thought to be behind the rapid and deep incisions that become fjords, made as ice sheets flow down from the mountains. Mark Kessler of the University of Colorado at Boulder and his colleagues now reckon the process is simpler than that.
