John McCain keeps up the global warming fight, Willie Nelson saves horses, The Governator terminates his bad rep, and more.

Last week, California Governor Arnold Schwarzenegger and British Prime Minister Tony Blair signed a mission statement to take "urgent action to reduce greenhouse gas emissions and promote low carbon technologies." Without mentioning specifics, the statement aligns California and the UK in their commitment to use market incentives to foster innovation in emissions trading and low carbon technologies, learn more about "the economics of climate change" and increase communication and collaboration among scientists and technological innovators. While the move sends an important message to President Bush, who has not acted aggressively on this issue, the pact itself is vague and non-binding. Is this just another empty gesture or does this partnership have what it takes to help save the planet?

Los Angeles deserves plaudits for many of its environmentally progressive initiatives – among them, fuel-efficient municipal vehicles and a pledge to generate 20 percent of its power from renewable sources by 2010. But much of this progress is rendered moot by the city's horrendous traffic-congestion problem, which stems from a sub-par – if not totally inadequate – public transportation system. Happily, The Governator and Mayor Antonio Villaraigosa are working on (or at least talking about) tackling the problem.
