Data are from the Global Snow Lab, Rutgers University, New Jersey, and the U.S. National Snow and Ice Data Center, University of Colorado, Boulder. Eric Post, et al., Ecological […]
ScienceDaily (Sep. 28, 2009) — Unusually high temperatures in the Arctic and heavy rains in the tropics likely drove a global increase in atmospheric methane in 2007 and 2008 after a decade of near-zero growth, according to a new study. Methane is the second most abundant greenhouse gas after carbon dioxide, albeit a distant second. […]
Northward expansion of insect herbivores such as the winter moth in northernmost Fennoscandia (intact mountain birch forest is shown in green, severely defoliated forest during the most recent outbreak in 2005 to 2008 is in dark brown, and tundra beyond the tree line is in white; reports of local winter moth outbreaks before the last […]
Change measurements are median filtered (10-km radius), spatially averaged (5-km radius) and gridded to 3 km, from intervals (Dt) of at least 365 d, over the period 2003–2007 (mean Dt is 728 d for Antarctica and 746 d for Greenland). East Antarctic data cropped to 2,500-m altitude. White dashed line (at 81.5° S) shows southern […]
Picturesque views of the snow-covered Alps may soon be relegated to picture books due to increasing climate change, a new European environmental report says.
