The First Secretary of Climate Change

Steven Chu, the new U.S. secretary of energy, is a Nobel-winning physicist and an unabashed advocate of fighting climate change. But can he negotiate the political realities of transforming the energy economy?

For years, Steven Chu argued that leadership on climate change should be wrested from the politicians and turned over to the scientists. But on Capitol Hill this April, on Earth Day, as Chu testified on the scientific merits of the most ambitious climate-change bill ever to come out of Washington, you might have wondered whether he regretted getting his wish.

Intergovernmental Panel on Climate Change
estimates that temperatures could rise by between
1.4 and 5.8C by the end of this century. BP's
position on this issue is clear. Greenhouse gas
levels are rising and the balance of scientific
opinion links that rise to the increase in our
planet's surface temperatures. As a major provider
of energy, we believe we have a responsibility to

For the Earth, the Heat Is On

Overwhelming atmospheric evidence supports the reality of global warming—and humans’ role in causing it

It was the summer of animals gone weird. Alaskan salmon swam up rivers they weren’t born in, their native streams reduced to trickles. Scores of subtropical species, including seahorses and leatherback turtles, migrated into waters off northern England and Scotland. Polar bears were marooned on a remote Arctic island as large patches of what was normally sea ice melted into water. Hundreds of thousands of seabirds failed to breed. The culprit for all this odd animal behavior? A Northern fever: from Alaska to Norway, meteorologists measured record-setting spring and summer temperatures.
