- PROPOSALS TO GEOENGINEER CLIMATE REQUIRE MORE RESEARCH, CAUTIOUS CONSIDERATION, AND APPROPRIATE RESTRICTIONS
Geoengineering - deliberately manipulating physical, chemical, or biological aspects of the Earth system to confront climate change – could contribute to a comprehensive risk management strategy to slow climate change but could also create considerable new risks, according to a policy statement released by the American Meteorological Society (AMS) today.

- Water Levels Dropping in Some Major Rivers as Global Climate Changes
Rivers in some of the world’s most populous regions are losing water, according to a new comprehensive study of global stream flow. The study, led by scientists at the National Center for Atmospheric Research (NCAR), suggests that in many cases the reduced flows are associated with climate change. The process could potentially threaten future supplies of food and water. UCAR News Center Abstract

- NIU researchers say nighttime tornadoes are worst nightmare
Twisters that occur from midnight to dawn are 2.5 times more likely to kill DeKalb, IL – A new study by Northern Illinois University scientists underscores the danger of nighttime tornadoes and suggests that warning systems that have led to overall declines in tornado death rates might not be adequate for overnight events, which occur most frequently in the nation’s mid-South region.

- Record warm summers cause extreme ice melt in Greenland
An international team of scientists, led by Dr Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. The new research provides further evidence of a key impact of global warming and helps scientists place recent satellite observations of Greenland´s shrinking ice mass in a longer-term climatic context.
