| 2012 sustained long-term climate warming trend, NASA finds Posted: 15 Jan 2013 04:02 PM PST Scientists say 2012 was the ninth warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the nine warmest years in the 132-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.  |
| Novel approach to track migration of arctic-breeding avian species Posted: 15 Jan 2013 04:02 PM PST A group of scientists have tried to determine how snow bunting populations are linked in space and time. Considering that the snow bunting poses an extra challenge to monitor due to its inaccessible breeding locations, nomadic lifestyle and small body size, they argue, combining multiple sources of data is the most appropriate approach to track patterns of the birds' migratory connectivity.  |
| Where there's smoke or smog, there's climate change Posted: 15 Jan 2013 12:35 PM PST In addition to causing smoggy skies and chronic coughs, soot -- or black carbon -- turns out to be the number two contributor to global warming. It's second only to carbon dioxide, according to a four-year assessment by an international panel. The new study concludes that black carbon, the soot particles in smoke and smog, contributes about twice as much to global warming as previously estimated, even by the 2007 Intergovernmental Panel on Climate Change.  |
| Global warming may have severe consequences for rare Haleakalā silversword plants Posted: 15 Jan 2013 11:39 AM PST While the iconic Haleakala silversword plant made a strong recovery from early 20th-century threats, it has now entered a period of substantial climate-related decline. New research warns that global warming may have severe consequences for the silversword in its native habitat.  |
