Last year was Earth’s hottest on record, U.S. scientists say

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) – Last year was Earth's hottest on record in new evidence that people are disrupting the climate by burning fossil fuels that release greenhouse gases into the air, two U.S. government agencies said on Friday. The White House said the studies, by the U.S. space agency NASA and the National Oceanic and Atmospheric Administration (NOAA), showed climate change was happening now and that action was needed to cut rising world greenhouse gas emissions. Last year was the warmest, ahead of 2010, undermining claims by some skeptics that global warming has stopped in recent years.
