Ecological Effects of Climate Change Include Human Epidemics
February 17 — The link between climate and cholera, a serious health problem in many parts of the world, has become stronger in recent decades, according to a University of Michigan scientist who takes an ecological approach to understanding disease patterns. (University of Michigan release) More

New Monsoon Forecasting Method Could Increase Crop Yields
February 17 — A recently devised method for forecasting monsoon-season weather in Bangladesh could improve agricultural production in south Asia and equatorial Africa, according to a climate researcher at the Georgia Institute of Technology. (Georgia Institute of Technology release) More

Can Carbon Sequestration Solve Global Warming?
February 17 — While the U.S. Government spends millions of dollars to research the feasibility of creating carbon sinks to combat global warming, a scientist at the American Association for the Advancement of Science (AAAS) Annual Meeting argues that the government isn't thinking big enough in its plans to remove carbon dioxide from the atmosphere.

Methane and Mini-Horses: Fossils Reveal Effects of Global Warming
February 16 — The past offers clues to how climate change will affect the future, say scientists who are studying a period of warming that occurred about 55 million years ago. (University of Michigan release) More

Ozone Levels in Southern California Smog May be Higher than Current Air Quality Models Predict
February 10 — Current air-quality models used for predicting air pollution may be underestimating ozone levels in Southern California by as much as 10% of the national one-hour ozone standard, a UC Irvine study has found. (University of California-Irvine release) More
