Barrier Islands Disappearing as Arctic Thaws
16.06.2011
A survey recently published in the Journal of Coastal Research, has determined that there are 2,149 barrier islands around the world, spanning a total of 20,783 km of coastline. Seventy-four percent of these islands are found in the northern hemisphere, where two thirds of the world’s land mass lies, and…

Climate Change Might Be Too Much for Siberia’s Boreal Forests
30.04.2011
According to a study recently published in the Environmental Research Letters by researchers from Nagoya University in Japan, the larch trees dominating the boreal forest of Siberia might not survive even the most optimistic climate change scenario of a 4°C increase in summer temperature in Siberia by the year 2100.…

Thawing Permafrost Will Likely Speed up Global Warming by 2200
21.02.2011
According to a new study recently published in Tellus B, the Earth could lose two-thirds of its permafrost by 2200, releasing incredible quantities of carbon dioxide into the atmosphere. Not only will this release have a significant impact on the climate, scientists say, but it will influence international climate change…
