New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth’s polar regions.
The study, titled “Coal Burning Leaves Toxic Heavy Metal Legacy in [...]
Information gleaned from a Greenland ice core by an international science team shows that two huge Northern Hemisphere temperature spikes prior to the close of the last ice age some 11,500 years ago were tied to fundamental shifts in atmospheric circulation.
The ice core showed the Northern Hemisphere briefly emerged from the last ice age some [...]
New research suggests that ocean temperature and associated sea level increases between 1961 and 2003 were 50 percent larger than estimated in the 2007 Intergovernmental Panel on Climate Change report.
The results are reported in the June 19 edition of the journal Nature. An international team of researchers, including Lawrence Livermore National Laboratory climate scientist [...]
Analysis of Antarctic ice cores led by Kenji Kawamura, a visiting scientist at Scripps Institution of Oceanography, UC San Diego, shows that the last four great ice age cycles began when Earth’s distance from the sun during its annual orbit became great enough to prevent summertime melts of glacial ice. The absence of those melts [...]

Leading climatologist Professor Stefan Rahmstorf has revealed at a UNSW public lecture that sea-level rises caused by global warming are higher than those published by the Intergovernmental Panel on Climate Change earlier this year.
Professor Rahmstorf, who is from the Potsdam Institute for Climate Impact Research, is being hosted in Sydney by UNSW’s Climate Change Research [...]
