WASHINGTON, DC, June 6, 2008 (ENS) – The U.S. Senate's much anticipated tangle with a landmark bill that would have required the nation to make deep cuts in greenhouse gas emissions responsible for global warming came to an unceremonious end Friday, as proponents failed to muster enough votes to formally consider the legislation.

Four days of deliberations on the climate bill were marked more by partisan bickering than substantive debate, but supporters of aggressive U.S. action to combat global warming contend the tide is turning in their favor.

"This is a landmark day," said Senator Barbara Boxer, a California Democrat and cosponsor of the bill. "It's another milestone in the fight against global warming."

Friday's 48-36 vote fell a dozen votes short of the number needed to end debate and begin consideration of amendments to the bill.

Seven Republicans joined 39 Democrats and two Independents in voting to move forward with the bill. Four Democrats sided with 32 Republicans in opposition.

Convinced most Republicans had little interest in actually trying to move the bill forward, Democratic leaders opted to pull the legislation from the floor.
