It's been a tumultuous week in Madison, Wisconsin. Tens of thousands of state workers, teachers, and students have packed the state Capitol building to protest Republican Gov. Scott Walker's plan to weaken public unions.

In a move ostensibly aimed to balance the state budget, Walker proposed a bill on Friday, February 11 that would dislodge collective bargaining rights for all public workers except for police, firefighters and the state patrol -- some of the few public employee unions that supported Walker's gubernatorial campaign. In addition, the bill will require most state workers to pay significantly more for pensions and health premiums.

The world series of climate change is just around the corner. Next week, global leaders will convene in Copenhagen to discuss how the world will address climate change. The United States and China, who together exhaust 40% of the world’s emissions, have already committed to reducing their carbon output. But will it be enough? In an interview with Paul Jay of The Real News, British environmental writer George Monbiot, argues that the cuts major leaders are proposing don’t match up with what the science demands.

On Wednesday, President Obama pledged to cut U.S. carbon emissions “in the range of” 17% below 2005 levels by 2020. Obama also confirmed that he will attend the international climate conference in Copenhagen next month, as Aaron Wiener notes for the Washington Independent. But here’s the catch: It’s a one-day deal. Obama is only planning to stop by Copenhagen on Dec. 9 before flying to Oslo to accept his Nobel Peace Prize. The climate talks, on the other hand, span Dec. 7 to Dec. 18.

Last weekend in Singapore, President Barack Obama acknowledged that a comprehensive international climate deal will not be reached during the climate change summit in Copenhagen. While many might view this as a letdown, lowering expectations might actually be a good thing, as Matthew Yglesias notes for the American Prospect. According to Yglesias, the conference can now be framed as a relative success whatever happens, and that will keep the momentum for climate action going after Copenhagen.

For weeks, Sen. Max Baucus (D-MT) has opposed climate change legislation. In the Environment and Public Works (EPW) Committee, he openly voiced his doubts and was the only Democrat to refrain from voting for the bill’s passage. Now that the bill is in the Finance Committee, which Baucus chairs, many worry that the bill is doomed. However, it looks like Baucus might have outwitted us all.

Aaron Wiener of the Washington Independent reports that Baucus’s opening statement at the Finance Hearing on Tuesday was surprisingly favorable. Baucus pledged his commitment to “passing meaningful, balanced climate change legislation” and even preempted economic attacks on the bill.

Senate Democrats in the Environment and Public Works Committee (EPW) finally squelched Republican boycotts and passed a version of the climate bill yesterday morning. Last week, Republican Senators refused to show up to committee hearings in an attempt to stall the bill. Brian Beutler of Talking Points Memo notes that EPW has now set “the stage for other panels to amend the legislation.”

To no one’s surprise, Sen. James Inhofe (R-OK) immediately complained about the legislation on Fox News. Sen. Max Baucus (D-MT) was the lone Democrat that did not vote, which Inhofe interpreted as a sign that the bill is “dead.”

This week the Senate Environment and Public Works Committee held three hearings on the Kerry-Boxer clean energy bill and, as David Roberts reports for Grist, Republican Senators had an “adolescent tantrum” about the cost of emission reductions. The Environmental Protection Agency (EPA), Congressional Budget Office, Energy Information Administration and other organizations have extensively debunked this line of debate.

After several prominent members left the Chamber of Commerce over its prehistoric climate change policies, the organization appeared to do an about-face on its climate stance during a press conference on Monday. Sound too good to be true? It was.

The U.S. might not have to go to December’s climate change talks in Copenhagen empty handed. Two weeks after Senators John Kerry (D-MA) and Barbara Boxer (D-CA) unveiled a new draft of the climate change bill, Kerry and Sen. Lindsey Graham (R-SC) announced their bipartisan partnership to pass climate change legislation in an op-ed for the New York Times.  By working together, the two hope to appeal to their respective party’s interests and help the climate change bill get 60 votes in the Senate.

President Barack Obama was awarded the Nobel Peace Prize today for his accomplishments in international diplomacy, climate change and attempts to curb nuclear proliferation. The Nobel Committee praised Obama for his “constructive role in meeting the great climatic challenges the world is confronting,” but, Richard Kim of The Nation wonders the award comes too soon, as Obama has not yet committed to attending the international climate summit at Copenhagen.
