Satellite Images of Devastation in Burma

NASA's Terra satellite captures startling before and after pictures of the coast of Burma

Tropical Cyclone Nargis slammed the Burmese coast with 130 mph winds and bursts of up to 160 mph—the equivalent of a category 3 or low-level category 4 hurricane. It reportedly led to thousands of deaths, and as of Monday, thousands more were missing. Now NASA has released a set of images that show how drastically the flooding has drenched Burma's coast.

Hurricane, Climate Change Link Explained

MIT professor Kerry Emanuel tries to correct the misinterpretations of his latest research

MIT meteorologist Kerry Emanuel got a ton of attention in 2005 when he published a paper in Nature demonstrating a link between global warming and hurricanes—especially since Katrina hit New Orleans just three weeks later.

The Risks of Geoengineering

One proposed fix for the planet's climate problems could create more problems than it solves

When it comes to climate change, a quick fix won't do. Science published a paper Friday from the National Center for Atmospheric Research (NCAR) which concludes that a proposed plan to inject the atmosphere with sulfate particles in order to cool the planet would actually have dire consequences.

The Green Screen

Can TV succeed where science has failed? Quite possibly, if David Attenborough is involved

In the fifty-some years since Sir David Attenborough began producing shows about Earth's wildlife, our planet has changed considerably. Population has skyrocketed. Cities have grown and spread to accommodate massive influx from the countryside. Species have become endangered; extinct. And amidst it all, Attenborough—the famed British TV naturalist and by some accounts the world's most-traveled human—has borne witness.

Surprise! Hybrid Sales on the Rise

More people are buying hybrid cars, but the greener vehicles are still a relative rarity on the road

In 2007, registrations of new hybrid vehicles jumped by 38 percent to 350,289 vehicles, according to a new report from R.L. Polk & Company. Gee, I wonder why? Maybe it's got something to do with rising prices at the pump, or climate change. Or maybe there's something bigger at play.

Under the Eye of the Hurricane

Researchers find that listening for storms underwater can help them predict intensity

MIT researchers have proposed a strange new way to predict the severity of a hurricane: Listening underwater. Currently, the most common way to gauge a storm's strength is to either study satellite images (which can be pretty inaccurate), or fly a weather plane straight on into the storm and gather critical data (which gets expensive).

Animated Map Visualizes Greenhouse Gas Sources

Where U.S. carbon dioxide emissions come from...and where they go.

A new system for mapping carbon dioxide emissions in the U.S. will help regulators figure out exactly where these emissions are coming from and how best to reduce them. Among human-produced gases that contribute to climate change, carbon dioxide is public enemy number one.

Cosmic Rays and Climate Change

A pair of particle physicists bust up a theory about cosmic rays and global warming

Yes, the Intergovernmental Panel on Climate Change has said that man is at the root of most of Earth's warming in the last five decades. Still, some researchers say the trend can be attributed to natural causes, including changes in the flux of cosmic rays slamming into our atmosphere, but now, according to Physics World, a pair of U.K. particle physicists have dismissed that idea.

Al Gore's Alliance For Climate Protection Begins Three-Year Ad Campaign

The product? Global warming awareness

As far as TV history goes, public service announcements will go down as a small but memorable slice of the great broadcast pie. The weeping Native American, brought to tears by the garbage strewn across his great country's highways. "Knowing is half the battle." "This is drugs; this is your brain on drugs." And so on.

Now, Al Gore and his Alliance for Climate Protection group have begun a privately funded PSA of their own with hopes of rallying the general public to the cause of preventing a global climate crisis.

Designing Greener Dirt

British scientists try to engineer soils that suck carbon out of the air

Getting carbon dioxide out of the atmosphere is just one step. After plants and trees pull CO2 out of the air, some of the surplus carbon is funneled down into the soil, where it can then re-enter the atmosphere or seep into groundwater. To trap this excess carbon, Newcastle University scientists are trying to design new kinds of soils that would transform the stuff into calcium carbonate, keeping it down in the ground.
