If current melting trends continue, the Arctic Ocean is likely to be free of summer sea ice by 2015, according to research presented at a conference organized by the National Space Institute at Technical University of Denmark, the Danish Meteorological Institute and the Greenland Climate Center. The estimates, which are consistent with some models presented […]
‘We all live on the Greenland ice sheet now. Its fate is our fate’ By Patrick Barkham at Sermilik fjord, Greenland It is calving season in the Arctic. A flotilla of icebergs, some as jagged as fairytale castles and others as smooth as dinosaur eggs, calve from the ice sheet that smothers Greenland and sail […]
By Matt Walker, Editor, Earth News Trees around the world are colonising new territories in response to higher temperatures. From the US west coast to northern Siberia and south-east Asia, trees are growing at higher elevations, and at higher latitudes as the climate warms. Of 166 sites studied, trees are advancing at more than half, […]
By Victoria Gill, Science reporter, BBC News Polar bears have shrunk over the last century, according to research. Scientists compared bear skulls from the early 20th Century with those from the latter half of the century. Their study, in the Journal of Zoology, describes changes in size and shape that could be linked an increase […]
