Hans Joachim Schellnhuber, chair of an advisory council known by its German acronym, WBGU, is a physicist whose specialty, fittingly, is chaos theory. Speaking to an invitation-only conference at New Mexico's Santa Fe Institute, Schellnhuber divulged the findings of a study so new he had not yet briefed Chancellor Angela Merkel about it.
The WBGU study says the United States must cut emissions 100 percent by 2020--i.e., quit carbon entirely within ten years. Germany, Italy and other industrial nations must do the same by 2025 to 2030. China only has until 2035, and the world as a whole must be carbon-free by 2050.
"I myself was terrified when I saw these numbers," Schellnhuber said. He urges governments to agree in Copenhagen to launch "a Green Apollo Project." Like John Kennedy's pledge to land a man on the moon in ten years, a global Green Apollo Project would aim to put leading economies on a trajectory of zero carbon emissions within ten years. Combined with carbon trading with low-emissions countries, Schellnhuber says, such a "wartime mobilization" might still save us from the worst impacts of climate change.
