Why did the guru cancel six coal plants?

One of the biggest climate stories of 2007 never made it to the business pages. It's about how Warren Buffett, with no fanfare, quietly walked away from coal, cancelling six proposed plants.

Buffett used to love coal. His involvement with it began when Berkshire Hathaway bought MidAmerican Energy Holdings in 1999. MidAmerican was a big operator of coal plants, and with natural gas prices edging toward a huge leap upwards -- bringing coal back into favor -- it appeared to be a typically savvy Buffett move.

In 2006, Buffett picked up another utility, PacifiCorp, which includes Rocky Mountain Power and operates in Calif., Idaho, Ore., Utah, Wash., and Wyo. Again, it seemed like a smart play, bringing MidAmerican's expertise with building and running coal plants to a region of the country with lots of coal. Sure enough, in the fall of 2006, PacifiCorp presented regulators with plans [PDF] for six (or, in some scenarios, seven) coal plants in Utah and Wyo. over the next 12-year time period, representing approximately 3,000 megawatts of new capacity.

China announces clean-air proposals for Olympic Games

Many Beijing-area factories and cement plants will close for two months beginning in late July as a key part of the effort to clean the city’s famously polluted air for the Olympic Games, Chinese officials said. Other clean-air measures include banning the use of half the city’s 3.5 million vehicles, disallowing spray paint and other […]

A letter from a climate scientist to Nevada’s governor

The following is a open letter to Nevada Governor Jim Gibbons from noted climate scientist James Hansen.

-----

Dear Governor Gibbons,

I am honored to be the recipient of the Desert Research Institute's annual Nevada Medal this year and to attend the awards ceremonies hosted by you and the First Lady.

I hope that I may communicate with you as a fellow parent and grandparent about a matter that will have great effects upon the lives of our loved ones. I refer to climate change, specifically global warming in response to human-made carbon dioxide (CO2) and other pollutants. This topic has long remained in the background, but it is now poised to become a dominant national and international issue in years ahead.

Global warming presents challenges to political leaders, but also great opportunities, especially for your state. Nevada has the potential to be a national leader in protecting the environment and implementing technologies that can mitigate the crisis posed by global warming.

First, however, I want to make you aware of rapid progress in understanding of global warming. Warming so far, averaging 2 degrees Fahrenheit over land areas, is smaller than weather fluctuations. Yet it already has noticeable effects and more is "in the pipeline," even without further increases of CO2, because of climate system inertia that delays the full climate response.

Effects of global warming are already seen in Nevada. One result is increased wildfires. Longer summers mean more dried out fuels, allowing fires to ignite easier and spread faster. The wildfire season in the West is now 78 days longer than it was 30 years ago. And the average duration of fires covering more than 2,500 acres has risen five-fold.

As the planet continues to warm, these and other impacts will grow worse for Nevada and the American West. The world's leading climate researchers conclude that, if greenhouse gases continue to increase, the region faces:

One month’s worth of data laughable as proof of global cooling

A top NASA scientist just emailed me the breaking news: "The ice age expired!"

Even more shocking: the rate of warming this year has been just about unprecedented in the historical record -- even faster than I had predicted just last month based on the NASA data from February.

Just look at the NASA Goddard Institute for Space Studies dataset. While January's land-ocean global temperature was a mere +0.12 degrees C above the the 1951-1980 average and the February anomaly was +0.26 degrees C -- the March anomaly was a staggering +0.67 degrees C.

(Warning: the following chart is not suitable for children or those who believe in global cooling. Please cover their eyes since the 2008 data, plotted in red below, might give them nightmares.)

What people in malls really want

Thirty years ago, high crop prices caused environmental destruction, too

Last week, I wrote about high crop prices that were inspiring people to make all manner of dubious land-use decisions, like plowing up environmentally sensitive land to plant environmentally destructive corn. Then I came across an interesting bit from Merchants of Grain: The Power and Profits of the Five Giant Companies at the Center of […]

How expensive is food, really?

There is no doubt whatsoever that rising food costs are hurting people all over the world. More than half of the world's population spends 50 percent of their income or more on food, and the massive rise in staple prices threatens to increase famine rates drastically. We are already seeing the early signs of this in Haiti and in other poor nations.

It is also undoubtedly true that rising food prices are digging into the budgets of average people, including me. And I've got it easy. The 35 million Americans who are food insecure (that is, they may or may not go hungry in any given month, but they aren't sure there's going to be food) are increasingly stretched. Supportive resources like food pantries are increasingly tapped. And regular folks are finding that food and energy inflation are cutting into their budgets substantially. The rises in food and energy prices alone have eroded real wages by 1.2 percent. The USDA chief economist has announced that overall food prices will probably rise by another 3 to 4 percent this year, and grain products will rise considerably more.

But there's another side to this coin. Rising food prices are, to some extent, good for farmers. Certainly, large grain farmers in the U.S., Canada, and many other rich nations have been experiencing a well deserved boom. And there are plenty of people, myself included, who have been arguing for years that we don't pay enough of the true costs of our food. Who is right? How do you balance the merits and demerits of food prices?

Big urban parks sprouting across the U.S.

Four major cities are poised to create urban parks several times bigger than New York’s iconic Central Park, itself a not-at-all-shabby 843 acres. In Orange County, Calif., a portion of a former air station will become a 1,347-acre park; in Memphis, a 4,500-acre former prison farm has been snatched from developers by a conservation easement; […]
