NOAA, NASA:  2014 Is Officially Hottest Year on Record, Driven by Global Warming

The National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) officially declared 2014 the hottest year in 134 years of record keeping.

NOAA reported that this was the hottest December on record and that 2014 as a whole was 1.24°F (0.69°C) above the 20th century average:  “This was the highest among all years in the 1880-2014 record, surpassing the previous records of 2005 and 2010 by 0.07°F (0.04°C).”

As the NOAA data makes clear, human-caused global warming has seen no “hiatus.”  In fact, as the top figure shows, the decade of the 2010s is on track to be the hottest decade on record.  The 1980s were the hottest decade on record at the time.  Then they were beat by 1990s, which in turn were beat by the 2000s for the title of hottest decade.  Each decade this century is likely to be the hottest on record — unless we slash carbon pollution ASAP.

“This is the latest in a series of warm years, in a series of warm decades,” said Dr. Gavin Schmidt director of NASA’s Goddard Institute of Space Studies, which tracks global temps.  “While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases.”

“The globe is warmer now than it has been in the last 100 years and more likely in at least 5,000 years,” said Rutgers University climate scientist Jennifer Francis.  “Any wisps of doubt that human activities are at fault are now gone with the wind.”
