New research shows that we should be looking to the ground, not the sky, to see where climate change could have its most perilous impact on life on Earth.

California has spearheaded efforts among the U.S. states to pass far-reaching laws on energy and the environment, sometimes bypassing the federal government. California governor Arnold Schwarzenegger is urging state and provincial leaders around the world to follow that example. Mike O'Sullivan reports, a California conference brought pledges of support to fight climate change from regional officials in 19 countries.

University of British Columbia researchers have found a way to accurately predict the impact of climate change on imperilled Pacific salmon stocks that could result in better management strategies.

In a global world, significant factors affect the spread of infectious diseases, including international trade, air travel and globalized food production. "Airport malaria" is a term coined by researchers to explain the more recent spread of malaria to areas such as the United States and Europe, which some scientists credit to warmer climate changes.

A rapid, climate change-induced northern migration of invasive marine is one of many research results announced Tues. Nov. 11 during opening day presentations at the First World Conference on Marine Biodiversity, Ciudad de las Artes y las Ciencias, in Valencia.

Earth scientists are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation.

A fix for the economy must address ecological threats, a top international scientific meeting here has urged. Human society is moving dangerously beyond the planet's natural limits in a striking parallel to the financial debt crisis. “We're running the planet like a subprime loan,” Dr. Johan Rockström of the Stockholm Resilience Centre said. A coordinated response would reduce the risks of both kinds of crises in the future.

Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.

Chinese history is replete with the rise and fall of dynasties, but researchers now have identified a natural phenomenon that may have been the last straw for some of them: a weakening of the summer Asian Monsoons.

A "living fossil" tree species is helping a University of Michigan researcher understand how tropical forests responded to past climate change and how they may react to global warming in the future.

New research by the University of East Anglia (UEA) has demonstrated for the first time that human activity is responsible for significant warming in both polar regions.

Biologists have long suspected that amphibians, whose moist permeable skins make them susceptible to slight changes in the environment, might be good bellwethers for impending alterations in biodiversity during rapid climate change.
