- Earth's Early Ocean Cooled More Than a Billion Years Earlier than Thought November 11, 2009
The global ocean covering the Earth 3.4 billion years ago was far cooler than has been thought, according to researchers who analyzed isotope ratios in rocks formed on that ancient ocean floor. (Stanford University press release)
- Controversial New Climate Change Data November 10, 2009
New data show that the balance between the airborne and the absorbed fraction of CO2 has stayed approximately constant since 1850, despite emissions of CO2 having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. (University of Bristol press release)
- Study Uses Satellite Imagery to Identify Active magma Systems in East Africa's Rift Valley November 4, 2009
Satellite images compiled over a decade to study volcanic activity in Kenya's section of the African Rift show deformation of four active volcanoes, which underscores the possibility for human hazard. (University of Miami press release)
- Paleoecologists Offer New Insight into How Climate Change will Affect Organisms November 4, 2009
