What makes a disaster? Does this blizzard count?

Actually, this is a meta-blog: A blog about a blog.

Not had enough of the snow yet?

Voices: If global warming is real, why is it snowing in DC?

Over the last week, I’ve heard a lot of people say, “If global warming is real, why is it still snowing in Washington, D.C.?”

Well, I have a response: It’s weather, not climate.

Blogging on EARTH: "Climategate" scientist tells his side

SAN FRANCISCO: In November, hackers broke into the e-mail server of the University of East Anglia’s Climate Research Unit and stole thousands of e-mails dating back to 1996 written by and to climate scientists. The e-mails, which were then leaked to the public, contained the typical stuff of science (and of e-mails, for that matter): amid discussions of data and theory, there was debate, confusion, flippancy, dark humor and questioning.

Blogging on EARTH: A proposed twist on carbon trades at AGU

SAN FRANCISCO: In the ongoing climate negotiations, one issue that keeps coming up is that developing countries should be held to the same standards as the developed world.

But that’s not quite fair, say Steven Davis and Ken Caldeira (both at the Carnegie Institution for Science in Stanford, Calif.): Much of the carbon dioxide emitted by those developing countries goes into producing goods that are exported to the developed world — which means the developing world ends up paying for others’ consumerism. In other words, we’re outsourcing our carbon dioxide emissions.

Storing CO2 in fizzy water underground

Burying carbon dioxide in underground geologic formations is an attractive option for dealing with increasing carbon dioxide in the atmosphere. But before employing such schemes, researchers need to be sure that the greenhouse gas will actually stay put. Scientists have done everything from computer modeling to pumping vast amounts of carbon dioxide into the subsurface to find out if — and how — the gas might be trapped, but gauging how sealed the formations are over geologic time scales is difficult.

Nanoscale carbon capture

Thanks to a bit of luck, the key to carbon sequestration may lie in a circular, bowl-shaped compound that draws carbon dioxide right out of the air.

Down to Earth With: Randy Olson

Marine biologist-turned-filmmaker Randy Olson made a name for himself in 2006 with the release of his first feature-length movie, “Flock of the Dodos: The Evolution-Intelligent Design Circus.” He followed that success with last year’s “Sizzle: A Global Warming Comedy.” These movies feature hot-button science issues, but they are not documentaries. Rather, Olson says, they are designed to entertain and spark an interest in the scientific topic — whether evolution or climate change — so that viewers will want to learn more.

White House climate report: U.S. changes already apparent

Blogging on EARTH

The climate status report released today by the White House includes no new research; instead, it is a synthesis of existing scientific data and studies. But the report sums up this information by adding a firm message: The United States is already feeling the impact of climate change — and should therefore take mitigating action sooner rather than later.

Glaciers present a complicated tale

Going, going, gone. That’s the popular view of the fate of glaciers in the American West because of climate change. But that may not be quite true. Glaciers throughout the region are shrinking, but not at the same rates. Some are actually advancing, and others have shown relatively little retreat since the 1970s. New research shows that the retreat story is not just about temperature, but ultimately about the connections between temperature, topography, precipitation and location.
