For climatologists, part of the challenge in predicting the future is figuring out exactly what happened during previous periods of global climate change. http://www.physorg.com/news164464266.html Space & Earth Wed, 17 Jun 2009 13:31:54 EST news164464266 The Amazon is surprisingly sensitive to drought, according to new research conducted throughout the world's largest tropical forest. The 30-year study, published today in Science, provides the first solid evidence that drought causes massive carbon loss in tropical forests, mainly through killing trees. http://www.physorg.com/news155485964.html Space & Earth Thu, 05 Mar 2009 14:34:20 EST news155485964 Carbon dioxide will continue to rise even if current national and international targets for reducing emissions are met, scientists warn. But, they say, strong action taken now - such as the 80% target recently announced by the UK government - will continue to have benefits a long time into the future. http://www.physorg.com/news144419668.html Space & Earth Tue, 28 Oct 2008 13:34:28 EST news144419668 (PhysOrg.com) -- In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences. http://www.physorg.com/news142260761.html Space & Earth Fri, 03 Oct 2008 13:52:41 EST news142260761 University of Alberta scientists contend they have the answer to mass extinction of animals and plants 93 million years ago. The answer, research has uncovered, has been found at the bottom of the sea floor where lava fountains erupted, altering the chemistry of the sea and possibly of the atmosphere. http://www.physorg.com/news135432196.html Space & Earth Wed, 16 Jul 2008 13:03:16 EST news135432196
