WH Science Adviser: Make CO2 Emissions ‘Close to Zero’

White House Science Adviser John Holdren says the global goal is to have world-wide carbon dioxide emissions “close to zero by 2100.” He admitted, “That will not be easy.”

As part of the White House “Open For Questions” video posted last week, Holdren was asked: “Do you know the rate of reduction in carbon emissions the world would have to achieve in order to prevent an unstoppable process of methane release from the Arctic areas?”

“No one knows for sure how much warming would be enough to produce this result, but it’s thought to be considerably less likely to happen if the ultimate warming is less than 2 degrees Celsius, that is 3.6 degrees Fahrenheit above the pre-industrial value, than if the ultimate warming is greater than that,” Holdren responded.
