Republicans for Environmental Protection explains McCain ranking (or lack thereof)
Republicans for Environmental Protection gave John McCain a “no score” on its just-released 2007 congressional scorecard, as David pointed out earlier. McCain missed all 14 of the votes on which REP scored senators, but the group opted not to give him a zero. Grist called David Jenkins, government affairs director for REP, to find out […]

An NC farmer makes the radio
Listen Play the interview One of my favorite things about small-scale farming has been meeting other small-scale farmers. In short, you’ve got to be a bit of a character to decide to spend your days playing in the dirt while also trying to squeeze a living out of it. Gallows humor is a typical characteristic, […]

EDF airs another ad in support of the Climate Security Act
Environmental Defense Fund is running another ad in support of the Lieberman-Warner Climate Security Act, this one in Washington, D.C., and other markets around the country. It features a talking, businessman-shaped candle melting while offering a bunch of the tired excuses one hears about why climate legislation is a bad idea. “Sure, climate change is […]

Hansen: Governors aren’t getting it
My recent experience with governors raises a question about whether this is an effective way to communicate about climate change. (Apologies for the length -- you may skip the three tales and go to the bottom line.)
Dear Governor Pawlenty [PDF]
Minnesota Gov. Pawlenty presides over a population that appreciates nature. Explorer Will Steger has done a marvelous job of informing the public there about climate change in the Arctic, the threat of climate change to species and indigenous people, and the relevance of climate change to Minnesota. Early actions made it appear that Minnesota would be a leader, defining energy policies and directions that would be a great example for other states.
Specifically (get this!), in spring 2007 Minnesota passed and Gov. Pawlenty signed a law called the Next Generation Energy Act of 2007, requiring 25 percent renewable energy by 2025 and a 1.5 percent per year improvement in energy efficiency.
Some people used this to help paint Gov. Pawlenty green, second in greenness only to Arnold Schwarzenegger among Republican governors. Pawlenty, according to the Washington Post, is at the top of the list of candidates to be John McCain's running mate. Coincidentally, the Republican convention will be in Minnesota in September. But ... read on.

Researchers aim to turn animal waste into plastic
File this under “ew”: Researchers in New Zealand have developed a process to convert animal protein waste — that’d be blood and feathers — into plastic. “The material we can produce has the strength of polyethylene, the plastic used in milk bottles and plastic supermarket bags, but it’s fully biodegradable,” says Dr. Johan Verbeek, adding, […]

Two scientists offer a grim preview of where humanity is headed
Feel like you’re just not depressed enough today? Read the last bit of this Dot Earth post: During a break, I asked [Nobel prize-winning atmospheric chemist Dr. F. Sherwood] Rowland two quick questions. The first: Given the nature of the climate and energy challenges, what is his best guess for the peak concentration of carbon […]

Forests and fires foster fearsome feedbacks
Previously, I looked at why the permafrost won't be perma for long. Then I looked at whether the potential destruction of the tundra represents the point of no return for the climate, necessitating that we keep atmospheric concentrations of carbon dioxide below 450 ppm or else risk going to 800 ppm to 1,000 ppm. Here I examine two local amplifying feedbacks that further threaten the permafrost: forests and fires.
Reduced snow cover and albedo (reflectivity) in the summertime Arctic landscape, caused by global warming, has added local atmospheric heating ($ub. req'd) "similar in magnitude to the regional heating expected over multiple decades from a doubling of atmospheric CO2." That same Science study warns "Continuation of current trends in shrub and tree expansion could further amplify this atmospheric heating 2-7 times."

A new blog takes on the enemy of the human race
This week marked the launch of Coal is Dirty. (It is “a joint project managed by The DeSmog Project, Rainforest Action Network, and Greenpeace U.S.A.”) The site is devoted to battling Big Coal’s PR machine. They’ve got some great writers involved, including Jeff Goodell (author of Big Coal) and Jeff Biggers. Bookmark it.

White House admits humans causing climate change
The White House has begrudgingly admitted that “most of the recent global warming is very likely due to human generated increases in greenhouse gas concentrations.” In a 271-page report — court-ordered and four years late — federal scientists have created a “one-stop shop” summary of potential climate impacts on the U.S. environment, economy, and public […]
