CHICAGO (Reuters) - President-elect Barack Obama's team to address climate change emerged on Wednesday as Democratic officials said he had chosen a Nobel laureate for U.S. energy secretary and was likely to pick an environmental veteran to serve as coordinator of climate policies.
Rounding out his cabinet, Obama planned to announce at a Chicago news conference on Thursday that former Senate Majority Leader Tom Daschle, a South Dakota Democrat, would lead efforts to improve the U.S. health care system as the secretary of Health and Human Services.
Simmering in the background is the scandal involving Illinois Gov. Rod Blagojevich, who was arrested on Tuesday and charged with attempting to sell the U.S. Senate seat that Obama had held until he was elected president on November 4.
Obama on Wednesday called on Blagojevich to resign and has sought to distance himself from the disgraced governor.
Announcements to come in the days ahead include several key environment-related appointments -- Steven Chu as energy secretary, Carol Browner as energy and climate coordinator, Nancy Sutley to head the White House Council on Environmental Quality and Lisa Jackson to run the Environmental Protection Agency.
They will be charged with developing policies to reduce carbon emissions blamed for global warming, develop new sources of energy and create new jobs -- a top priority for Obama.
Chu is director of the Lawrence Berkeley National Laboratory and shared the 1997 Nobel Prize in physics. He was an early advocate for scientific solutions to climate change.
Browner was administrator of the Environmental Protection Agency during the Clinton administration. A principal at global strategy firm The Albright Group LLC, she heads Obama's advisory team on energy and the environment.
Sutley has a long history in the environmental community. She is currently deputy mayor for energy and environment for Los Angeles and served on the California State Water Resources Control Board earlier this decade.
Jackson has served as commissioner of the Department of Environmental Protection in New Jersey.
46 MILLION UNINSURED AMERICANS
A big challenge for Obama and Daschle will be extending health insurance coverage to millions of uninsured Americans and determining whether to reshape a system that is currently employer-based.
Close to 46 million Americans have no health insurance, and Americans are more likely to die of common diseases than people living in many other developed countries.
Daschle has already been involved in considering ways to improve the system. Obama's transition team in the second half of this month will hold a series of meetings across the country to discuss ways to change the way health care is delivered.
During the campaign, Obama pledged to bring health insurance to millions of uninsured Americans and spend about $50 billion to make U.S. health records electronic. Continued...
According to reports, Barack Obama, the President-elect of the United States, will nominate Steven Chu, a Nobel Prize-winning physicist, to be his Secretary of Energy.
Steven Chu in 2005
Chu has been  the director of the Lawrence Berkeley National Laboratory in California for the past four years. He shared the Nobel Prize in physics in 1997 with Claude Cohen-Tannoudji and William Daniel Phillips for developing ways to cool and trap atoms with a laser light.

In the past, Chu was the head of an electronics lab at the Bell Labs in New Jersey. He has also worked on solar technologies and global warming, and is a professor at the University of California. Chu has worked on ways to develop carbon-neutral energy.

Chu is currently scheduled to travel Asia and Europe and is expected to be back at work on Monday, according to a spokesperson at Lawrence Berkeley.
