“Epidemiological” Study Demonstrates Climate Change Effects on Forests

National Science Foundation: "Epidemiological" Study Demonstrates Climate Change Effects on Forests Study of 27,000 trees shows early spring warming, summer drought as major factors Some 280,000 tree-years of data show that magnolias are vulnerable to climate change. An 18-year study of 27,000 individual trees by National Science Foundation (NSF)-funded scientists finds that tree growth and fecundity--the ability to produce viable seeds--are more sensitive to climate change than previously thought. The results, published...

Ancient Catastrophic Drought Leads to Question: How Severe Can Climate Change Become?

National Science Foundation: How severe can climate change become in a warming world? Worse than anything we've seen in written history, according to results of a study appearing this week in the journal Science. An international team of scientists led by Curt Stager of Paul Smith's College, New York, has compiled four dozen paleoclimate records from sediment cores in Lake Tanganyika and other locations in Africa. The records show that one of the most widespread and intense droughts of the last 50,000 years or more...
