2015 was the Hottest Year on World Record, Says NASA and NOAA

As per the report released by two US government agencies on Wednesday, the global average temperature was the hottest by the wide margin on record in 2015. The U.S. space agency NASA and the National Oceanic and Atmospheric Administration (NOAA) has come up with the fact that the average temperature across global land and ocean surfaces was 1.62 degrees Fahrenheit (0.90 Celsius) above the 20th century average in 2015, surpassing 2014's previous record by 0.29 F (0.16 C).

The two US agencies said that this was the fourth time a global temperature record has been set this century. Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, said 2015 marked the history in the context of the larger, long-term warming trend. In the contiguous United States, the year was the second-warmest on record, punctuated by a December that was both the hottest and the wettest since record-keeping began. Few months ago, scientists started predicting a global temperature record because of the El Niño weather pattern, one of the largest in a century.

El Niño is releasing an immense amount of heat from the Pacific Ocean into the atmosphere that warms the ocean surface every two to seven years. But, scientists believe human activities like burning of fossil fuels, wood, charcoal to be responsible for greenhouse gas emissions resulting in change in climatic conditions. Thomas Karl, director of NOAA's National Centers for Environmental Information, said the 2015 data continues the pattern we've seen over the last four to five decades. If the world really wants to hold temperature increases to well below 2 degrees C, the target agreed to by more than 190 countries at climate talks in Paris last December, there is vital need to cut greenhouse gas emissions.

Gavin said "Is there any evidence for a pause in the long-term global warming rate? The answer is no. That was true before last year, but it's much more obvious now".
