Poison solar

In the rush to encourage solar power production, governments aren't paying enough attention to the toxic chemicals employed in the manufacturing process.

According to the Silicon Valley Toxics Coalition, the gas sulfur hexafluoride, commonly employed to clean reactors in silicon production, is considered by the Intergovernmental Panel of Climate Change to be “the most potent greenhouse gas per molecule; one ton of sulfur hexafluoride has a greenhouse effect equivalent to that of 25,000 tons of carbon dioxide.”

The manufacturing of solar power panels consumes a lot of silicon, presenting us with a nasty paradox. If solar power production is ramped up as part of a global effort to reduce the greenhouse gas emissions produced by burning fossil fuels, the chances of accidental releases of sulfur hexafluoride in the silicon production process will only increase, which, says the SVTC, could “greatly undermine the reductions in greenhouse gas emissions gained by using solar power.”

Trench warfare rages over Keystone pipeline

The GOP tries every which way to undo the Greens' modest victory

When the Obama administration announced last month that the Keystone pipeline project would be delayed pending a more thorough environmental review of its impacts, Keystone’s opponents celebrated, but warned that the fight was far from over. Sure enough, pipeline politics remain front-and-center as those in favor of the pipeline seek to circumvent the longer review process while its opponents struggle to fend off attacks on their tenuous victory. The past few weeks have seen a burst of legislative maneuvering as Republicans seek a way to rubber-stamp the pipeline without the president’s approval.

Climate change denial’s new offensive

Global warming is wreaking devastation, but Big Oil won't give up profits without a planet-destroying fight

If we could see the world with a particularly illuminating set of spectacles, one of its most prominent features at the moment would be a giant carbon bubble, whose bursting someday will make the housing bubble of 2007 look like a lark. As yet — as we shall see — it’s unfortunately largely invisible to us.

In compensation, though, we have some truly beautiful images made possible by new technology. Last month, for instance, NASA updated the most iconic photograph in our civilization’s gallery: “Blue Marble,” originally taken from Apollo 17 in 1972. The spectacular new high-def image shows a picture of the Americas on January 4th, a good day for snapping photos because there weren’t many clouds.

Wind power: Renewable resource, or another corporate scam?

A fascinating new film about one small-town political fight takes on the pseudo-green wind industry

A still from "Windfall"

In telling the story of a small-town political fight over wind power, Laura Israel’s fascinating documentary “Windfall” at first seems like another entry in the long laundry list of post-”Inconvenient Truth” doomsayer environmental films. Indeed, “Windfall” has some of the rural, homespun feeling of Josh Fox’s Oscar-nominated “Gasland,” which helped ignite a national debate over the natural-gas extraction method known as fracking. Israel’s film also offers a direct riposte to Bill Haney’s “The Last Mountain,” in which Robert F. Kennedy Jr. is seen promoting wind power as a clean alternative to the dirty and destructive combination of mountaintop-removal coal mining and coal-generated electricity.

LIMA, Peru — International negotiators are closing in on a new solution for combating climate change — and saving the world’s remaining forests.

Global Post

Some 20 percent of all greenhouse-gas emissions now come from deforestation, especially in the lush, green band of tropical rainforest that circles the earth.

That is more than from global transport.

Big government, our one shot against crazy storms

In our age of devastating droughts, wildfires and hurricanes, the federal government is more important than ever

Look back on 2011 and you’ll notice a destructive trail of extreme weather slashing through the year. In Texas, it was the driest year ever recorded. An epic drought there killed half a billion trees, touched off wildfires that burned four million acres, and destroyed or damaged thousands of homes and buildings. The costs to agriculture, particularly the cotton and cattle businesses, are estimated at $5.2 billion — and keep in mind that, in a winter breaking all sorts of records for warmth, the Texas drought is not yet over.
