WASHINGTON, April 14 (UPI) -- Without aggressive action now, it will be hard to keep greenhouse gas emissions in check long term, U.S. Energy Secretary Ernest Moniz said.
A report from the Intergovernmental Panel on Climate Change warns international efforts to reduce carbon emissions are short of what's needed to keep expected temperature increases in check. Greenhouse gas emissions would have to be close to zero by the end of the century to keep changing weather patterns from growing more severe.
