"What the U.S. and China do over the next decade," declared Energy Secretary Steven Chu, the Nobel Prize – winning physicist who is leading President Obama's push for a clean-energy economy, "will determine the fate of the world."

Chu had gone to Beijing's Tsinghua University, the "MIT of China," to make his half-apocalyptic, half-optimistic pitch about climate change. In his nerdy professor style and referring to "Milankovitch cycles" and the "albedo effect" as well as melting glaciers and rising seas, Chu methodically explained that the science is clear, that we're boiling the planet - but also that science can save us, that we can innovate our way to sustainability. He acknowledged that the developed nations that made the mess can't tell the developing world not to develop, but he also warned that China is on track to emit more carbon in the next three decades than the U.S. has emitted in its history; that business as usual would intensify floods, droughts and heat waves in both countries; that greenhouse gases respect no borders. This earth, he concluded, is the only one we've got; it would be illogical and immoral to fry it. "Science has unambiguously shown that we're altering the destiny of our planet," he said. "Is this the legacy we want to leave our children and grandchildren?" (Read "The Global Warming Survival Guide.")
