NASA scientist warns of mass extinction from global warming
James Hansen, director of NASA’s Goddard Institute for Space Studies, warned Wednesday that human-made climate change could lead to the deaths of millions of species.
“If we continue with business as usual this century, we will drive to extinction 20 to 50 percent of the species on the planet,” he told Current TV host Eliot Spitzer. “We are pushing the system an order of magnitude faster than any natural changes of climate in the past.”
In a recently published study, Hansen and his team concluded that the drastic increase in record high temperatures in recent years could be directly traced to human-made climate change, particularly the increase in greenhouse gases.
“If we want to stabilize the climate at levels not much warmer than it is now, we need to begin to reduce emissions now, within the next few years,” he told Spitzer. “We’re gonna have to reduce carbon dioxide emissions, and that is not as difficult as you think. If we would just make fossil fuels pay for their true cost to society, we could begin to move to different energies and energy efficiency.”
