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:

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; […]
