According to the National Oceanic and Atmospheric Administration, 2015 easily broke the previous record for the warmest year that had been set just the previous year.
During 2015, the average temperature across global land and ocean surfaces was 1.62 Fahrenheit (0.90 Celsius) above the 20th century average,” said the NOAA report.
“This was the highest among all years in the 1880-2015 record.”
Compared to 2014, last year was 0.29 Fahrenheit (0.13 Celsius) warmer, the “largest margin by which the annual global temperature record has been broken.”
2015 also had ten months that set the records for warmth. Scientists believe that even without this year’s large El Nino effect, the record would have been broken but that it added to the size of the effect.
Of course this is not a record to celebrate. NASA says that that “the temperature changes are largely driven by increased carbon dioxide and other human-made emissions into the atmosphere.”
Remember 1997, the warmest year up to that point which climate change deniers would use as their starting point because it enabled them to claim for few years that the Earth wasn’t significantly warming? Well, that argument now goes down the tubes because 16 of the 18 years since then have been warmer.
