2017 was among the planet's hottest years on record, government scientists report

NATION-NOW     Federal scientists say 2017 among warmest years on record     
       2017 was among the warmest years on record

The minor difference in rankings is due to the different methods used by the two agencies to analyze global temperatures, although over the long-term the agencies' records remain in strong agreement.

In a separate study using different analytical methods, National Oceanic and Atmospheric Administration (NOAA) ranked past year as the third-warmest in their records.

In NOAA's report, during 2017, the average temperature across global land and ocean surfaces was 1.51 degrees Fahrenheit (0.84 degrees Celsius) above the 20th century average.

2017 was the second-hottest year ever recorded, according to a new NASA report.

"The global temperature figures for 2017 are in agreement with other centres around the world that 2017 is one of the three warmest years and the warmest year since 1850 without the influence of El Niño", said Dr Colin Morice from the Met Office. But it adds that 2016's temperatures were heightened by an El Niño event.

Sea ice and global snow cover also declined in 2017, which further contributed to global warming; with fewer reflective surfaces on the planet, more sunlight could thereby be absorbed by the continents and oceans, driving temperatures higher, the scientists explained. Not every year will be warmer than the last because of natural variations, but the trend over years will be rising temperatures, they said.

Either way, scientists say it showed a clear signal of man-made global warming because it was the hottest year they've seen without an El Nino boosting temperatures naturally.

Describing the accelerating pace of climate change as "an existential threat to the planet", the Secretary-General's Special Representative for Disaster Risk Reduction, Robert Glasser, said, "A three-year streak of record hot years, each above 1° Celsius, combined with record-breaking economic losses from disasters in 2017 should tell us all that we are facing an existential threat to the planet which requires a drastic response".

Prior to this report, 2015 was ranked as the second hottest year and 2014 as the third hottest.

Hausfather's group, Berkeley Earth, also found that 2017 was the second hottest year on record.

Using those inputs, the United Nations said that the average global surface temperature previous year was 1.1 degrees Celsius (1.98 degrees Fahrenheit) above pre-industrial levels.

2017 was 1.12 degrees Celsius above late 19th century temperatures, according to Gavin Schmidt, who directs NASA's Goddard Institute for Space Studies.

The restored data of climate shift, made by human discharges of greenhouse gases, occurs as the Trump government proposes to prepare fresh fields for oil drilling and moves back laws that attempted to decrease global warming, most prominently by pushing to abolish the Obama government's Clean Power Plan.
