Ancient climate change may portend toasty future

Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon. This finding contradicts the position held by many climate-change skeptics that the Earth system is resilient to such emissions.

   01-15-2008 · EurekAlert!
   A four-man science team led by British Antarctic Survey's Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. The lake -- the size of Lake Windermere -- could yield vital clues to life on Earth, climate change and future sea-level rise.

2. Ancient coral reef tells the history of Kenya's soil erosion
   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.

3. Radar opens new window into the ice for Antarctic scientists
   10-16-2006 · EurekAlert!
   Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS). Getting a clearer view of how ice behaves is important because it will help scientists predict more accurately how the ice sheet will respond to future climate change. The results are published this week in the Journal of Glaciology.

   University of Alaska Fairbanks climate scientist John Walsh is among the lead authors of the second volume of the Fourth Assessment Report from the Intergovernmental Panel on Climate Change. The volume, "Impacts, Adaptation and Vulnerability," analyzes how climate change is affecting natural and human systems. It also examines future effects of climate change and how adaptation can reduce those effects. Walsh was a lead author of the chapter on polar regions.

10. Impact of climate change in Africa
    11-24-2006 · EurekAlert!
    Africa is the continent that will suffer most under global warming. Past history gives us lessons on the likely effects of future climate change. Of greatest concern are the "large infrequent disturbances" to the climate as these will have the most devastating effects. In a study from the Kenyan Tsavo National Park published today in the African Journal of Ecology, Dr. Lindsey Gillson uncovers evidence for a drought that coincided with a harrowing period of Maasai history.
