In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan.

The Chaiten volcano now erupting in southern Chile is one of 200 to 300 volcanoes in the "Andean Arc" region of Chile, Peru, Ecuador and Columbia considered active by volcanologists, some of which lie in much more densely populated areas, said a University of Colorado at Boulder geologist who has studied Chaiten.

The old adage, “We are what we eat,’’ may be the latest recipe for success when it comes to curbing the perils of global climate warming.

“Think globally, act locally” makes for a nice bumper sticker — but is it an effective policy for coping with global climate change? Can local actions make a difference in a process principally driven by worldwide trends?

The senior science advisor to the World Climate Research Programme (WCRP) has called for the establishment of a Southern Hemisphere network of deep ocean moorings to detect any change in ocean circulation that may adversely influence global climate.

Tropical deforestation, which releases more than 1.5 billion metric tons of carbon to the atmosphere every year, is a major contributor to global climate change. Recognizing this, a group of forest-rich developing nations have called for a strategy to make forest preservation politically and economically attractive.

As U.S. policy-makers prepare for hearings later this week on space-science and climate-change research, the world's largest general science society today warned that budget cuts are threatening U.S. satellites essential for weather forecasting, hurricane warning, studies of global climate change and more.

A recent study in Nature1 suggested that terrestrial plants may be a global source of the potent greenhouse gas methane, making plants substantial contributors to the annual global methane budget. This controversial finding and the resulting commotion triggered a consortium2 of Dutch scientists to re-examine this in an independent study.

Changes in growth rates in some coastal and long-lived deep-ocean fish species in the south west Pacific are consistent with shifts in wind systems and water temperatures, according to new Australian research published in the United States this week.

Climate change could trigger "boom and " population cycles that make animal species more vulnerable to extinction. , according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz.
