Half of world's population could face climate-driven food crisis by 2100

"Ignoring climate projections at this stage will only result in the worst form of triage."

The headline is from the University of Washington news release on a study in Science, "Historical Warnings of Future Food Insecurity with Unprecedented Seasonal Heat" ($ub. req'd). The quote is the study's powerful final sentence. The release explains:

Rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, new research shows ...

"The stresses on global food production from temperature alone are going to be huge, and that doesn't take into account water supplies stressed by the higher temperatures," said David Battisti, a University of Washington atmospheric sciences professor.

Worse, the study must also be considered a serious underestimate of likely impacts since, as is common in such analyses, they based their simulations on "the 'middle of the road' emission scenario, A1B." In 2100, A1B hits about 700 ppm with average global temperatures "only" about 3°C warmer than today. In fact, on our current emissions path, we are going to get much, much hotter.

Figure. "Histogram of summer (June, July, and August) averaged temperatures (blue) observed from 1900 to 2006 and (red) projected for 2090 for (A) France, (B) Ukraine, and (C) the Sahel. Temperature is plotted as the departure from the long-term (1900-2006) climatological mean (21). The data are normalized to represent 100 seasons in each histogram. In (A), for example, the hottest summer on record in France (2003) is 3.6°C above the long-term climatology. The average summer temperature in 2090 [assuming A1B] is projected to be 3.7°C greater than the long-term climatological average."

The results are still alarming:

Will Congress get a whiff and vote to clean up dirty diesel engines?

The Washington Post has an interesting note about the armada of diesel buses that have rolled into the nation's capital for the Obama inauguration -- and the need to clean them up.

The opportunity for the "policy change" described in the piece could be at hand as soon as the day after the inauguration, Wednesday, Jan. 21, when the House Appropriations Committee takes up the economic recovery bill. The committee already recognized the desire to include the cleanup of existing diesel engines as part of the stimulus bill. See the bottom of page 4 of the House plan [PDF], which includes $300 million for a diesel green jobs program.

Washington Post is staffed with people who found no mistakes in George Will's denial

After my debunking of George Will's recent column collection of error-filled denier talking points [redundant], it became somewhat of a sport on the internet (see here). I had written:

I don't know whether it is more pathetic that Will believes this or that the Washington Post simply lets him publish this lie again and again.

Now we know it is the latter, thanks to Brad Johnson at WonkRoom, who got this jaw-dropping email from Post ombudsman Andy Alexander:

Basically, I was told that the Post has a multi-layer editing process and checks facts to the fullest extent possible. In this instance, George Will's column was checked by people he personally employs, as well as two editors at the Washington Post Writers Group, which syndicates Will; our op-ed page editor; and two copy editors.

Paging Woodward and Bernstein. [The CP fact checker notes that Woodward abandoned journalism based on facts, at least checkable facts, many years ago.]

Both of my parents were professional journalists, and I must say that response makes me want to cry. I could understand Will's people stooges signing off on his crap -- they drink from the same pitcher of Kool-Aid. And I could understand if the Post said that they don't fact-check opinion pieces.

But there is no clearer evidence of how far traditional journalism has sunk than that five different editors associated with the Washington Post signed off on a piece that brings to mind Mary McCarthy's famous quip about Lillian Hellman:

Every word she writes is a lie -- including 'and' and 'the.'

I am not going to redebunk Will here point-by-point, but I will excerpt the devastating response to the ombudsman's lazy defense of Will penned by Hilzoy of the Washington Monthly. After you read it, I'm sure you will want to give Andy Alexander (ombudsman@washpost.com) -- "the reader's advocate" -- a piece of your mind (and please do repost it in the comments).

Tennessee coal ash spill contains high levels of toxic heavy metals

According to some just-released test results, the coal ash at the Harriman sludge spill contains high levels of toxic heavy metals, some up to 300 times the legal limit:

According to the tests, arsenic levels from the Kingston power plant intake canal tested at close to 300 times the allowable amounts in drinking water, while a sample from two miles downstream still revealed arsenic at approximately 30 times the allowed limits. Lead was present at between twice to 21 times the legal drinking water limits, and thallium levels tested at three to four times the allowable amounts.

All water samples were found to contain elevated levels of arsenic, barium, cadmium, chromium, lead, mercury, nickel and thallium. The samples were taken from the immediate area of the coal waste spill, in front of the Kingston Fossil plant intake canal just downstream from the spill site, and at a power line crossing two miles downstream from the spill.

This comes via the Appalachian Voices blog, a great source of breaking info and pictures from the spill. Full release beneath the fold:

On the importance of getting personal with your food

Real food doesn't often compete with the delicious paper-and-ink smell of bookstores, but last Saturday, chefs, farmers, photographers, and writers filled Seattle's Elliott Bay Book Company with their wares: two appetizing reads. The back-to-back book events featured the authors of Chefs on the Farm and Edges of Bounty.

One lesson I walked away with that day was that food is only as good as the relationships on which it's based. These relationships can be between soil and seed, eater and herb, farmer and goat, or even you and your neighbors. Both books' authors reinforced this idea and went on to suggest that diverse, well-tended, and personal relationships produce the best meals and the best stories.
