Climate Vote 2007

This post is part of a series on the work of the Environmental Defense Action Fund to enact an effective climate law. You can help by writing to Congress.

Last night's committee passage of the Lieberman-Warner Climate Security Act (CSA) means that the bill now can be considered by the full Senate - an important step towards enacting national climate legislation. But for a bill to become law in this country it has to be passed by both the House and Senate, and the House is lagging behind. (See our previous post for more on the legislative process.)

Today's post is by Bill Chameides, Ph.D., science adviser to Environmental Defense and member of the National Academy of Sciences.

When it comes to solving climate change, our best yardstick for measuring success is how much we cut global warming pollution. The Energy Bill could make some progress, but it's no substitute for the comprehensive climate legislation Congress will work on later this year. Let's look at the numbers.

Bill Chameides is out of the office, but science, policy and news about global warming keep coming in. Yesterday, a group of military experts declared that climate change threatens national security (registration required). Their report [PDF] says:

Climate change can act as a threat multiplier for instability in some of the most volatile regions of the world, and it presents significant national security challenges for the United States…. The increasing risks from climate change should be addressed now because they will almost certainly get worse if we delay.
