The heat is on; NOAA, NASA say 2014 warmest year on record. WASHINGTON (AP) — For the third time in a decade, the globe sizzled to the hottest year on record, federal scientists announced Friday.Both the National Oceanic and Atmospheric Administration and NASA calculated that in 2014 the world had its hottest year in 135 years of record-keeping. Earlier, the Japanese weather agency and an independent group out of University of California Berkeley also measured 2014 as the hottest on record.
NOAA said 2014 averaged 58.24 degrees Fahrenheit, 1.24 degrees above the 20th-century average.
But NASA, which calculates temperatures slightly differently, put 2014's average temperature at 58.42 degrees Fahrenheit, which is 1.22 degrees above their average, which they calculate for 1951-1980.
NOAA also said last month was the hottest December on record. Six months last year set marks for heat. The last time Earth set a monthly cold record was in December 1916.
"The globe is warmer now than it has been in the last 100 years and more likely in at least 5,000 years," said climate scientist Jennifer Francis of Rutgers University, who wasn't part of either research team. "Any wisps of doubt that human activities are at fault are now gone with the wind."
Texas A&M University climate scientist Andrew Dessler and other experts said the latest statistics should end claims by non-scientists that warming has stopped.
The heat was driven by record warmth in the world's oceans that didn't just break old marks: It shattered them. Record warmth spread across far eastern Russia, the western part of the United States, interior South America, much of Europe, northern Africa and parts of Australia. One of the few cooler spots was in the central and eastern United States.
