Climate change messing with ecology worldwide, study says

Climate change is messing with ecology worldwide right now, according to a comprehensive new study in the journal Nature. Researchers examined data on shifts in over 28,000 plant and animal systems and over 800 environmental changes across all the world’s continents for the past 30 years. In 90 percent of the cases of change in […]

The delayers’ paradox

The primary goal of the global warming deniers and their disciples is to waste time and delay action, which is why I prefer to call them delayers.

(This post is inspired by the surprising finding that only 27 percent of conservatives say the earth is warming because of human activity, such as burning fossil fuels.)

The delayers' paradox

The deniers and delayers are those who argue that failing to embrace strict reductions in greenhouse-gas emissions will not lead to serious or catastrophic impacts. The delayers' paradox is this: If we all actually were persuaded by the deniers and delayers, it would lead to levels of atmospheric GHG concentrations that ensure the most catastrophic impacts imaginable, proving them (fatally) wrong.

How three Southeast cities are changing

For more on Southeast cities, see our full feature on sustainability initiatives underway in Atlanta. With rapid population growth and increased climate vulnerability, the Southeastern U.S. would seem a prime place for sustainability initiatives. But the area has been slow to cotton on to the greening trend. We chalk it up to the South’s shade-shifting […]

Big increases coming in electric costs

From the "Things Grist readers already knew" file comes this report from ClimateWire ($ub. req'd) that price shocks are looming for power plant operators, even before the costs of carbon are factored in.

A few excerpts below the fold:

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 […]

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?

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:

Drink beer, fight climate change

Many efforts to fight climate change involve some kind of sacrifice. This invention, however, merely requires the drinking of lots and lots of beer. I see it as a game-changer in the debate over the best way to incentivize a solar market.

And I would have gotten away with it, if it wasn’t for you meddling kids!

One thing you frequently hear from nuclear proponents is that nuke plants would pencil out fine if not for all those pesky safety regulations, NIMBYs, lawsuits, protests, and other political ephemera. If we could just get rid of that stuff! But that’s a market democracy. It’s not like failing because everyone hates you and tries […]

Bush DOE says wind can be 20 percent of U.S. power by 2030 — with no breakthroughs

The Bush administration has signed off on a stunning new report [PDF], "20 Percent Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply."

I am working on a big wind article for midweek, but here are the key conclusions of what is easily the most comprehensive and credible report released on wind power in a decade:
