Obama names 4 top members of science team

John Holdren and Jane Lubchenco are leading experts on climate change who have advocated forceful government action. Holdren will become Obama's science adviser as director of the White House Office of Science and Technology Policy. Lubchenco will lead the National Oceanic and Atmospheric Administration, which oversees ocean and atmospheric studies and does much of the government's research on global warming.

Holdren also will direct the president's Council of Advisers on Science and Technology. Joining him as co-chairs will be Nobel Prize-winning scientist Harold Varmus, a former director of the National Institutes of Health, and Massachusetts Institute of Technology professor Eric Lander, a specialist in human genome research.

"It's time we once again put science at the top of our agenda and worked to restore America's place as the world leader in science and technology," Obama said in announcing the selections in his weekly radio address.

The president-elect said promoting science means more than just providing money, but also is about ensuring that facts and evidence are never twisted or obscured by politics or ideology.

"From landing on the moon, to sequencing the human genome, to inventing the Internet, America has been the first to cross that new frontier because we had leaders who paved the way," Obama said. "Leaders who not only invested in our scientists, but who respected the integrity of the scientific process."

The four scientists will confront challenges in global warming after years of inaction by the Bush administration, which opposed mandatory cuts of greenhouse gas pollution. Last year, former Surgeon General Richard Carmona testified to Congress that top administration officials often dismissed global warming as a "liberal cause" and sought to play down public health reports out of political considerations.

Since 1993, summer Arctic sea ice has lost the equivalent of Alaska, California and Texas, and global warming is accelerating. The amount of carbon dioxide in Earth's atmosphere has already pushed past the level some scientists say is safe.

Holdren, 64, is a former president of the American Association for the Advancement of Science in Washington who has pushed for more urgent action on global warming. As Obama's top science adviser, he would manage about 40 Ph.D-level experts who help shape and communicate science and technology policy.

"Global warming is a misnomer. It implies something gradual, something uniform, something quite possibly benign, and what we're experiencing is none of those," Holdren said a year ago in a speech at Harvard. "There is already widespread harm ... occurring from climate change. This is not just a problem for our children and our grandchildren."
