One of the most southerly populations of polar bears in the world – and the best studied – is struggling to cope with climate-induced changes to sea ice, new research reveals. Based on over 10 years' data the study sheds new light on how sea ice conditions drive polar bears' annual migration on and off the ice.

After more than a decade of sometimes bitter controversies and personal attacks, a new reconstruction of regional and global temperature anomalies since the last Ice Age strongly supports Michael Mann's 'hockeystick curve'. Global climate during the last decade is warmer than during three quarters of postglacial time and temperatures rise faster than ever before.

In a clever reuse of hardware originally built to test parts of NASA's QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction. The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth's climate.
