Melting Arctic ice poses security threat, says Pentagon

Waterways made navigable by melting Arctic ice pose a security threat to the northern U.S. border, says the Pentagon. The shrinking ice cap has led to increased interest in tourism and energy development in the Arctic, and the extra traffic makes the Pentagon wary. “The Arctic is a new area that is important to us […]

Wal-Mart tightens safety standards for toxics in toys

Wal-Mart, the world’s largest toy retailer, has told its suite of suppliers that they must meet new safety standards for toxics in toys by later this year. Some 25 million toys were recalled by toy makers last year in the United States, many due to high lead levels. Wal-Mart’s new standards apply to a range […]

Thinking beyond technology to mitigate climate change

If we quit adding carbon to the atmosphere, it won't stop global warming any time soon. That's why people are hoping there are ways to get the extra carbon out of the atmosphere, and that we can put billions of tons of it somewhere safe.

Breaking apart carbon dioxide -- or extracting carbon dioxide from the air -- takes work. Work means energy. It's the reverse of combustion. There's a triple problem here: the technology itself, the disposal, and the energy to do the work.

It's a common saying that you can't unscramble an egg. Once scrambled, the egg proteins won't go back to their raw configuration when they cool, and even if they did, it's impossible to wield a fork in such a way as to separate the yolk from the white. Roomfuls of the latest and greatest laboratory equipment, the best Google algorithms, or even all the king's horses and all the king's men would not unscramble our egg. The mixing and cooking are irreversible processes.

It's a familiar impasse. Can we change the way we see the problem?

McCain’s gas-tax holiday plan is at odds with his new climate strategy

Sen. John McCain made a climate speech Monday in which he argued that doing something about climate change is a "test of foresight, of political courage, and of the unselfish concern that one generation owes to the next." His timing is curious. "Ignore that man behind the curtain," his speech seemed to be saying. "You know, the man who is beating up on Sen. Barack Obama for refusing to support his gas-tax holiday proposal; the one who will be making it easier for Americans to consume greater amounts of carbon-rich fossil fuel." Of course, it is hard to ignore the man behind the curtain.

Whitehouse and Boxer want answers from EPA’s Johnson on Gade ouster

Sens. Barbara Boxer (D-Calif.) and Sheldon Whitehouse (D-R.I.) sent a letter to EPA Administrator Stephen L. Johnson today, calling for information about the circumstances surrounding the ouster of Mary Gade, the administrator of the agency’s Midwest regional office. Gade was allegedly fired after attempting to force Dow Chemical to clean up dioxin pollution around the […]

Dems and GOP agree to stop filling Strategic Petroleum Reserve

The Senate today approved legislation to temporarily suspend deliveries to the nation’s Strategic Petroleum Reserve, by a vote of 97-1. The measure was inserted as an amendment to a flood insurance bill, and was opposed only by Sen. Wayne Allard (R-Colo.). The Energy Department sends 70,000 barrels of oil to the reserve every day, a […]

Why it took us so long to internalize the rise in gas prices

With gas at $3.50 a gallon in April, the U.S. mainstream media is replete with stories of drivers abandoning SUVs, hopping on mass transit, and otherwise cutting back on gasoline. Yet a year or two ago, when pump prices were approaching and even passing the $3.00 "barrier," the media mantra was that demand for gasoline was so inelastic that high prices were barely making a dent in usage.

Which story is correct? I lean toward the more "elastic" view, and here I'd like to share some of the data that inform my belief.

I've been tracking official monthly data on U.S. gasoline consumption for the past five years and compiling the numbers in this spreadsheet. You'll find that it parses the data in several different ways: year-on-year monthly comparisons (e.g., March 2008 vs. March 2007), three-month moving averages that smooth out most of the random variations in reporting, and full-year comparisons that allow a bird's-eye view.

Here's what I see in the data:

Snippets from the news

Talking with voters in the Mountain State

This is the first in a series of dispatches from Melinda Henneberger, who's talking to voters around the U.S. about their views on the environment and the election.

Huntington, W.Va. -- Door-knocking for Barack Obama in a state where he expects to get stomped today has been kind of thankless for Pam Wonnell, a nurse and old friend of mine who moved here from Illinois last year for her husband's job in coal mining: "I am not feeling the love" while phone canvassing or standing on front porches watching the people inside pretend not to be home. "But I'm not quitting, 'cause I'm a fighter, like Hillary," she says, and laughs at her own joke. "Isn't that Hillary-ous?"

Canvassing with her in her hilly, aerobically "butt-busting" neighborhood on the eve of the Democratic primary, though, one surprise is the can't-wait-for-November enthusiasm for Obama among ... Republicans? Hmm. Another is that even -- or perhaps especially -- in this coal-mining state, where billboards along I-64 scream, "Yes, Coal" and "Coal Keeps the Lights On," voters say they want to hear candidates talk more about the environment, not less.

Brazil’s pro-rainforest environment minister resigns

Brazilian Environment Minister Marina Silva resigned Tuesday after six years in office, leading a Greenpeace campaigner to lament that “Brazil is losing the only voice in the government that spoke out for the environment.” Silva’s policies prioritized environmental protection, particularly for the Amazon; while her policies landed her a spot as one of Grist’s fave […]
