A new finding that suggests a similar outcome is possible in response to human-caused climate change, according to a University of Michigan paleontologist and his colleagues. Researchers have known for years that mammals such as primates and the groups that include horses and deer became much smaller during a period of warming, called the Paleocene-Eocene Thermal Maximum (PETM), about 55 million years ago....

Summit County: By now its no secret that global warming will have a significant impact on water supplies in parts of the world, and regions where water is already scarce will be first to feel the pinch That includes the interior West, where winter snowpack provides critical water storage. Already, projections show that spring runoff is coming much earlier than just a few years ago, and that, in many areas, more of the total annual precipitation is falling as rain. In a new study, a team of researchers tried...

Reuters: Total greenhouse gas emissions by China and other emerging nations since 1850 will surpass those of rich nations this decade, complicating U.N. talks about who is most to blame for global warming, a study showed on Thursday. Developing nations accounted for 48 percent of cumulative emissions from 1850 to 2010, according to the study by the PBL Netherlands Environmental Assessment Agency, research group Ecofys and the European Commission's Joint Research Center. "Somewhere in the current decade...
