California announces specifics of greenhouse-gas reduction plans

On Thursday, California state regulators released specific plans to reduce California’s greenhouse-gas emissions 10 percent from today’s levels by 2020, the first phase of a scheme to reduce emissions 80 percent by 2050. The bulk of the outlined reductions are designed to come from programs the state has already begun work on, but have been […]

Climate change means worse droughts for American Southwest, Australia

Part one presented the synopsis of the remarkable new U.S. Climate Change Science Program (a.k.a. the Bush Administration) report, Weather and Climate Extremes in a Changing Climate. One central point in the synopsis is

Droughts are becoming more severe in some regions, though there are no clear trends for North America as a whole ... Substantial areas of North America are likely to have more frequent droughts of greater severity.

Seems pretty clear, no? Dry areas will see more evaporation, hence less soil moisture (defined as precipitation minus evaporation), hence more drought. Further, many dry areas will see less precipitation under climate change (due to the expansion of the Hadley Cell and subtropics, see "Australia faces the 'permanent dry,' as do we").

Big Coal’s new video

A shill from everyone’s favorite Big Coal front group ABEC wanders the streets of D.C. asking totally unbiased questions: Next up: Do random passers-by prefer ponies and puppy dogs, or will they side with the environmentalists’ effort to kick the nation’s little old ladies in the shins?

Why indeed

“We have been talking about energy independence since Americans were waiting in gas lines during the 1970s. We’ve heard promises about it in every State of the Union for the last three decades. But each and every year, we become more, not less, addicted to oil — a 19th century fossil fuel that is dirty, […]

Global energy demand will grow 50 percent by 2030, says EIA

The world isn’t going to kick its energy-sucking habits anytime soon, the U.S. Energy Information Administration predicted Wednesday. By 2030, global energy demand will grow 50 percent, says the EIA report, mostly in China and other developing countries. Some 124 new nuclear plants will be built worldwide by 2030, and natural gas will be in […]

Hansen’s message to the planet

Maybe it was the thought of two decades of climate-crisis exhortation, little more heeded than words shouted at a hurricane.

Maybe it was the temporizing of the Democrats and the obstructionism of the GOP. Or it might have been the images of cities, houses and farmland of his native Iowa drowned by the latest "500-year" floods.

Perhaps it was all three. Whatever the reasons, the climate crisis' Paul Revere turned it up a few more notches in a speech yesterday (PDF) at a Congressional staff briefing in Washington D.C.

Yet James Hansen's headline-grabbing broadside against Big Oil and Big Coal CEOs may prove less significant than his full-throated advocacy of carbon tax-and-dividend as the highest priority for reducing carbon emissions and abating global warming:

A price on emissions that cause harm is essential. Yes, a carbon tax.

Climate change may force California endemic plants to migrate or die

Climate change is expected to significantly affect California’s endemic plants over the next century as temperatures rise and rainfall patterns change, according to a new study published in the journal PLoS One. Up to two-thirds of the state’s unique plants could be wiped out in their current ranges by century’s end and will have to […]

Offshore drilling has an ‘insignificant’ effect on oil prices

I am glad that so many in the energy debate have picked up on one of the two messages from my previous post (see "EIA to McCain: Drop offshore [drilling]").

But in listening to the radio and TV debates, I realize that some people have the impression that U.S. Energy Information Administration said offshore drilling might eventually lower oil prices. It did not. It found that allowing offshore drilling would have no significant effect on prices as far out into the future as the analysis projected.

Business consulting firm projects robust growth for solar and grid parity in many locations by 2020

McKinsey has a great new analysis piece: “The economics of solar power.” Overall it’s extremely optimistic, saying that despite uncertainties around technology and policy, growth in the solar sector is all but certain to be robust. Here’s a interesting chart. The size of the yellow ball is the size of the solar market in TWh. […]

Even U.S. government says human emissions are changing climate

The U.S. Climate Change Science Program (a.k.a. the Bush Administration) has issued a must-read report, Weather and Climate Extremes in a Changing Climate. It wouldn't be must-read or even big news if it weren't for the fact that

• Many environmentalists stopped talking about the extreme weather/global warming link a decade ago.
• The deniers, the delayers, and of course the Roger Pielkes of the world have pushed back against any claims that climate change is driving the extreme weather we see today. (as Chico Marx (dressed as Groucho) said "Who you gonna believe, me or your own eyes?")
• The media has been brow-beaten by the deniers into downplaying the connection. The journalist Ross Gelbspan has a long discussion of this in his great 2004 book, Boiling Point -- I will blog on this later.
• The Midwest is experiencing the second "500-year flood" in 13 years. (Don't worry, big media, it's all just a big coincidence like the deniers keep saying.)
