Congress tackles global warming

More than a dozen competing measures have been introduced in Congress on the issue of global warming -- some minor, such as creating incentives for biofuel research, and others more drastic, such as taxing automakers for selling gas-guzzling sport utility vehicles.

The Democrats controlling Congress -- and a growing number of Republicans -- say this year the government will take significant action against climate change. They say President Bush helped the cause by mentioning it in his State of the Union address last month, as have the presidential candidates pushing the issue.

House Speaker Nancy Pelosi, California Democrat, has promised to introduce a package of bills by June 1 aimed at cutting greenhouse gases, with a vote slated for July 4.

"As the most adaptable creatures on the planet, it is time for us to continue to adapt," she said Thursday, testifying on global warming before the House Science and Technology Committee. Mrs. Pelosi assured anxious colleagues that global-warming legislation "can create the next generation of good-paying new jobs."

Sen. Joe Lieberman, Connecticut independent and a chief author of a leading global-warming bill, said there is a "very diverse cavalry" calling for action. His Climate Stewardship and Innovation Act is co-sponsored by Sen. John McCain, Arizona Republican.

"Doing something about global warming now will cost us a lot less than waiting to pay the cost of the effects of global warming," Mr. Lieberman said of his bill, which imposes mandatory caps on greenhouse gas emissions so that in 2050 the levels would be one-third lower than 2000 levels.

It also would create emission credits to control the costs for businesses and encourage industries to comply, as well as protect poor people from high energy costs, he said.

Mr. McCain is running for president, as are Democratic Sens. Hillary Rodham Clinton of New York and Barack Obama of Illinois, who have also signed onto the bill as co-sponsors.

Mr. Obama talked about the issue in his announcement speech Saturday, saying: "We can turn this crisis of global warming into a moment of opportunity for innovation, and job creation, and an incentive for businesses that will serve as a model for the world."

The bill, which the Republican-led Senate defeated two years ago, this year faces a much friendlier group of lawmakers. The debate now stems over whether to impose mandatory emissions caps, and how much the government should aim to reduce heat-trapping gases in the next few decades.
