2016 declared hottest year on record

22 January 2017

"This was the third year in a row in our analysis to set a new record".

The information was gathered by NOAA's National Centers for Environmental Information and NASA, and they found that for "eight consecutive months, January to August, the globe experienced record warm heat".

In 2016, the average surface temperatures was recorded at 1.1C higher the levels recorded before the industrial revolution, when the large-scale burning of fossil fuel commenced.

The average temperature across global land and ocean surfaces was 58.69 degrees Fahrenheit, 1.69 degrees above the 20th century average, NOAA said Wednesday morning.

NASA credited carbon dioxide "and other human-made emissions into the atmosphere" for a rise by about 2.0 degrees in the Earth's average surface temperature since the late 19th century.

In a separate analysis of global temperature data, scientists from the USA space agency NASA also found 2016 to be the warmest on record.

"Even if you remove the extra warming due to El Nino, 2016 was the warmest year ever recorded", Forster said.

"We try to stay away from politics per se and we stay focused on what are the stories being told by artists". This year's festival, which begins this week, will be just as star-studded.

The poles felt the brunt of this warming trend, with the estimated average yearly sea-ice extent previous year in the Arctic appearing to be the lowest annual average on data. 2016 was also the 20th year in a row that the average annual temperature exceeded the average temperature. Most of this warming trend throughout the world has taken place in the last 35 years, the United States space agency said.

The Arctic was almost 7.2 degrees Fahrenheit hotter past year than in preindustrial period, a "very large change" according to Goddard Institute for Space Studies director Gavin Schmidt.

According to the Met Office, the phenomenon contributed about 0.2C to the annual average for 2016 while the remaining 0.9C was man-made.

NOAA scientists used much of the same raw temperature data, but with a different baseline period, and different methods to analyze Earth's polar regions and global temperatures. Scientists attributed the increase to both the temporary weather pattern known as El Niño and more permanent global warming caused by greenhouse gases.

A year ago was the end of an El Nino weather pattern, so 2017 is expected to be cooler rather than warmer. Australia recorded its fifth warmest year on record. "However, the main contributor to warming over the last 150 years is human influence on climate from increasing greenhouse gases in the atmosphere".

"We have also broken sea ice minimum records in the Arctic and Antarctic", he said, adding that the Arctic was warming twice as fast as the global average.
