For the third time in ten years, the globe sizzled to the hottest year on record, federal scientists announced on 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, Statesman reported. This isn’t the first group to say that 2014 was hotter than ever. Earlier, the Japanese weather agency and an independent group out of University of California Berkley also measured 2014 as the warmest on record.
NOAA said 2014 averaged 58.24 degrees Fahrenheit, 1.24 degrees above the 20th-century average.
NASA, calculating temperatures in a different manner, put 2014’s average temperature at 58.42 degrees Fahrenheit, which is 1.22 degrees above their average, which they calculate for 1951-1980.
Earth squashed NOAA records set in 2010 and 2005. The last time the Earth set an annual NOAA cold record was in 1911.
NOAA also said December 2014 was the hottest 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.”
The heat was propelled by record warmth in the world’s oceans. 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 cooler regions was in the central and eastern parts of the United States.
NOAA global records show that nine of the 10 hottest years have occurred since 2000. The odds of this happening at random are about 650 million to 1, according to University of South Carolina statistician John Grego. To additional statisticians confirmed his calculations.
“We are witnessing, before our eyes, the effect of human-caused climate change,” said Pennsylvania State University professor Michael Mann. “It is exceptionally unlikely that we would be seeing a record year, during a record warming decade, during a multi-decadal period of warmth that appears to be unrivaled over at least the past millennium if it were not for the rising of planet-warming gases produced by fossil fuel burning.”
