D.C.’s metro was extremely packed during Monday’s morning commute, which could only mean one thing (aside from it being tourist season): Congress is back in session.

I blogged earlier about the major flaws in the latest climate change legislation, America’s Climate Security Act, introduced by Sens. Joe Lieberman (I-Conn.) and John Warner (R-Va.) The Senate will be debating the bill all week, and although nobody expects the bill to get very far, it’s certainly creating a buzz among the media and some heated debate among lawmakers.

For those who want to get a feel for how the debate is going, Reuters has posted a sampling of some of Monday’s comments, from notaries such as President Bush, Al Gore and Sen. Barbara Boxer (D-Calif.).

Some other media highlights:

• A post from The New York Times’ political blog, The Caucus
• A list of five things to watch during the debate from The Politico
• A look at both sides of the debate from Wired
• An overview of business’ take on climate change from CQPolitics

And in case all these facts on climate change become a bit dizzying, check out the resources from Public Citizen’s energy program.
