The greenhouse gas methane is bubbling from Siberian lakes in greater volume that scientists had believed.

A series of giant pipes in the oceans to mix surface and deeper water could be an emergency fix for the Earth's damaged climate system, the scientist behind the Gaia theory said on Wednesday.

The world's governments must dramatically cut emissions of heat-trapping gases or learn to live with more droughts, heat waves, powerful rainstorms, and rising sea levels that will affect millions, leading climate scientists said after the release of a landmark global warming report yesterday.

Politicians in the nation's capital have been reluctant to set limits on the carbon dioxide pollution that is expected to warm the planet by 4 to 7 degrees Fahrenheit during the next century, citing uncertainty about the severity of the threat. But that uncertainty may have shrunk somewhat with the release last week of two scientific reports suggesting that global warming is not just a hypothetical possibility, but a real phenomenon that has already started transforming especially sensitive parts of the globe.

By Adam Shell and Matt Krantz Droughts. Hurricanes. Rising temperatures. Melting glaciers. In a world abuzz with talk about global warming, climate change is elbowing aside tech and biotech as the major investment theme of the future.

Scientists know that Earth endures cyclical ice ages, but they don't know why. Perhaps you do. In the Wired Wiki.

The letter "Global Space Junk" (BDN, May 19-20) strains credulity. Showing that temperature records from some specific locations fail to display consistent warming is meaningless. Climate change effects are not evenly spread over the planet.

The planet isn't the only thing heating up because of climate change. Some renewable-energy stocks have been pretty hot, too.

Scientists have long thought thick clouds over Saturn&#39;s moon Titan rained methane through smoggy skies. Some believed the liquid pooled on the planet&#39;s surface, perhaps forming lakes or seas reminiscent of Earth&#39;s.

NASA scientists reported that higher temperatures and a retreat of the sea ice over the last two winters offered new evidence that the gases were influencing the ArcticÂs climate.

Scientists are warning that the earth&#39;s climate could be changing more rapidly than anyone thought because of a sudden and unexplained rise in the main greenhouse gas, carbon dioxide.

The rate at which global warming gases are accumulating in the atmosphere has taken a sharp leap upwards, leading to fears that the devastating effects of climate change may hit the world sooner than predicted.

Crop switch likely to increase emissions Good science news (or bad, depending on your point of view) has arrived with two reports on the carbon footprint of biofuels, in the paper edition of Science magazine. They deal serious damage to the belief - which up to now has been driving the biofuel bubble - that stepped-up ethanol production in the US is an answer to global warming.â¦

Not all of the Arctic thaw is caused by man. Nature plays a role, too, but that doesn't let us off the hook for the damage we've done.

Carbon dioxide in the air is turning the oceans acidic, and without a reduction in emissions, coral reefs may die away by the end of the century, researchers warn in Fridayâs issue of the journal Science.
