Toll of climate change on world food supply could be worse than thought
12-03-2007 · EurekAlert!Global agriculture, already predicted to be stressed by climate change in coming decades, could go into steep, unanticipated declines in some regions due to complications that scientists have so far inadequately considered, say three new scientific reports. The authors say that progressive changes predicted to stem from 1- to 5-degree C temperature rises in coming decades fail to account for seasonal extremes of heat, drought or rain, multiplier effects of spreading diseases or weeds, and other ecological upsets.

- Soot from wood stoves in developing world impacts global warming more than expected
10-24-2006 · EurekAlert!
New measurements of soot produced by traditional cook stoves used in developing countries suggest that these stoves emit more harmful smoke particles and could have a much greater impact on global climate change than previously thought, according to a study scheduled to appear in the Nov. 1 issue of the American Chemical Society journal Environmental Science and Technology.

- Rising food prices threaten world's poor people
12-03-2007 · EurekAlert!
Income growth, climate change, high energy prices, globalization and urbanization are all converging to transform food production, markets and consumption, according to a new report by the International Food Policy Research Institute. As a result, global food demand and prices are likely to rise, threatening the livelihoods and nutrition of poor people in developing countries. The report, "The World Food Situation: New Driving Forces and Required Actions," was released today at the annual general meeting of the Consultative Group on International Agricultural Research.

- Scientists reveal first-ever global map of total human effects on oceans
02-14-2008 · EurekAlert!
More than 40 percent of the world's oceans are heavily affected by human activities, and few if any areas remain untouched, according to the first global-scale study of human influence on marine ecosystems. By overlaying maps of 17 different activities such as fishing, climate change, and pollution, the researchers have produced a composite map of the toll that humans have exacted on the seas.

- Studying rivers for clues to global carbon cycle
02-08-2008 · EurekAlert!
In the science world, media and our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. In a study of how organic carbon is processed in rivers, a research team including an engineer, ecologists and microbiologists has determined that carbon processing in rivers is a bigger component of global carbon cycling than previously thought. The team lays out a framework for how scientists should go about assessing those processes.

- Marine life stirs ocean enough to affect climate, says FSU study
10-13-2006 · EurekAlert!
Oceanographers worldwide pay close attention to phytoplankton and with good reason. The microscopic plants that form the vast foundation of the marine food chain generate a staggering amount of power, and now a groundbreaking study led by Florida State University in Tallahassee, Fla., has calculated just how much -- about five times the annual total power consumption of the human world.
