Just about everywhere you look ice is melting — see USGS report details “recent dramatic shrinkage” in U.S. glaciers, matching global decline. Here is a very impressive presentation from a 2009 TED (Technology, Entertainment, Design) conference: “Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers […]
IF THE sinking Maldives aren’t enough to galvanise action on climate change, could losing a classic beer do it? Climatologist Martin Mozny of the Czech Hydrometeorological Institute and colleagues say that the quality of Saaz hops – the delicate variety used to make pilsner lager – has been decreasing in recent years. They say the […]
Direct and rapid responses to recent Arctic climate change have included earlier flowering of plants in Greenland [replicate slopes for each genus are based on annual estimates from 1996 to 2008 in Zackenberg; adapted from T.

By Marlowe Hood and Richard Ingham (AFP) PARIS — Climate change will disrupt Earth’s precious ozone layer, boosting ultraviolet (UV) radiation in the deep southern hemisphere and reducing UV in far northern latitudes, a study warned on Sunday. By century’s end, UV levels in Antarctica could rise by up to 20 percent at seasonal peaks […]
Atlanta (September 8, 2009) —Tornadoes that occur from hurricanes moving inland from the Gulf Coast are increasing in frequency, according to researchers at the Georgia Institute of Technology. This increase seems to reflect the increase in size and frequency among large hurricanes that make landfall from the Gulf of Mexico. The findings can be found […]
By CHARLES J. HANLEY, Associated Press TUKTOYAKTUK, Northwest Territories — Caught between rising seas and land melting beneath their mukluk-shod feet, the villagers of Tuktoyaktuk are doing what anyone would do on this windy Arctic coastline. They’re building windmills. That’s wind-power turbines, to be exact — a token first try at “getting rid of this […]
