Cave records provide clues to climate change

Using stalagmites found in two different caves in Borneo, Georgia Tech researchers found that the tropical Pacific may play a much more active role in historic climate change events than was previously thought.

   04-10-2007 · EurekAlert!
   Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

5. Past greenhouse warming events provide clues to what the future may hold
   02-15-2008 · EurekAlert!
   Scientists studying an extreme period of global warming 55 million years ago are piecing together an increasingly detailed picture of its causes and consequences. Their findings describe what may be the best analog in the geologic record for the global changes likely to result from continued carbon dioxide emissions from human activities.

8. Salty oceans provide early warning for climate change
   06-08-2007 · EurekAlert!
   Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. Presenting their findings at a recent European Science Foundation (ESF) conference, scientists predicted that the waters of the southern hemisphere oceans around South Africa and New Zealand are the places to watch.

    Solar energy has the power to reduce greenhouse gases and provide increased energy efficiency, says a scientist at the US Department of Energy's Argonne National Laboratory, in a report (view it online) published in the March issue of Physics Today. Last month, The Intergovernmental Panel on Climate Change (IPCC) of the United Nations released a report confirming global warming is upon us and attributing the growing threat to the man-made burning of fossil fuels.
