Arctic sea ice drops below 2007 levels

Arctic sea ice extent just dipped below January 2007 levels in the last few days, according to the daily time series from the National Snow and Ice Data Center:

The NSIDC notes that they are showing the data from 2007 on this figure since that year "went on to reach the lowest summer minimum in the satellite record."

The NSIDC also has an interesting 2008 Year-in-Review for cryosphere buffs. It explains why the ice stopped growing for a week in mid-December. It also has an interesting graphic comparing the Arctic sea ice extent in 2008 with 2007:

Beef has 13 times more climate impact than chicken, 57 times more than potatoes

SciAm reports:

• Pound for pound, beef production generates greenhouse gases that contribute more than 13 times as much to global warming as do the gases emitted from producing chicken. For potatoes, the multiplier is 57.
• Beef consumption is rising rapidly, both as population increases and as people eat more meat.
• Producing the annual beef diet of the average American emits as much greenhouse gas as a car driven more than 1,800 miles.

I primarily focus on technology-based solutions since they can be the basis of government policy and since many websites are devoted to personal behavior choices, like No Impact Man.

Behavior-based strategies really only work on a large scale when societal values change (and/or prices jump) sharply, which is certainly inevitable in the coming years as more and more people come to grips with the increasingly painful reality of human-caused global warming (see "What are the near-term climate Pearl Harbors?") and realize just how immoral it is to maintain current levels of GHG emissions per capita at the expense of the next 50 generations to walk the earth (NOAA stunner: Climate change "largely irreversible for 1000 years," with permanent Dust Bowls in Southwest and around the globe).

For a good article on how one meat-loving environmentalist has changed his behavior, see Mike Tidwell's "The Low-Carbon Diet."

Next stop for Obama team: EPA's endangerment finding

Stopped EPA from blocking California's effort to regulate tailpipe GHG emissions. Check!

Stopped a new coal plant. Check!

The next "stop" on the Obama Climate Action Train is the "endangerment finding" so the EPA can finally put a stop on greenhouse gases.

In Massachusetts [vs. EPA], the Supreme Court found that greenhouse gases (GHGs) are "pollutants" under the Clean Air Act; that EPA must determine whether GHGs emitted from new motor vehicles do or do not endanger public health or welfare, or supply a reason for not making this determination; and that, if EPA makes an "endangerment finding," it must issue regulations.

The key question: Can elevated levels of GHG concentrations be reasonably anticipated to endanger public health or welfare? Does the Pope buy papal indulgences carbon offsets?

This is not a tough call for a President who just said: "climate change, which, if left unchecked, could result in violent conflict, terrible storms, shrinking coastlines, and irreversible catastrophe." And for 1,000 years! Indeed, he campaigned on this very issue (see the October 16 post, "Obama to declare CO2 a dangerous pollutant").

In an email to EPA employees [PDF], Administrator Lisa Jackson wrote of "five priorities that will receive my personal attention" -- the first of which is "Reducing greenhouse gas emissions":

As Congress does its work [on global warming legislation], we will move ahead to comply with the Supreme Court's decision recognizing EPA's obligation to address climate change under the Clean Air Act.
