Senate to push global warming bill this week?

This push, if it materializes, is surprising given that big Senate debate over health care. From Reuters:

A last-ditch attempt at passing a climate change bill begins in the Senate this week with senators mindful that time is running short and that approaches to the legislation still vary widely, according to sources.
"We will present senators with a number of options when they get back from recess," said one Senate aide knowledgeable of the compromise legislation that is being developed. The goal is to reduce emissions of carbon dioxide and other greenhouse gases that scientists say threaten Earth.
The options will be presented to three senators -- Democrat John Kerry, independent Joseph Lieberman and Republican Lindsey Graham -- who are leading the fight for a bill to battle global warming domestically.
The aide said the Senate's drive for a bill got a boost last week with President Barack Obama's announcement of an $8.3 billion government loan guarantee to help start expanding the nuclear power industry, a top Republican priority. "The administration is really putting their money where their mouth is," the aide said.
The Senate trio's success or failure likely will have a profound impact on international efforts to reduce carbon emissions and prevent Earth's temperature from exceeding a possibly dangerous 2 degree Celsius (3.6 Fahrenheit) increase from pre-industrial times. . . .
