The upward trend in global temperatures marked by record-shattering warmth in 2015 and 2016 kept pace last year, with the United Nations weather agency warning Thursday that continued pressure on the Arctic in 2017 will have “profound and long-lasting repercussions on sea levels, and on weather patterns in other parts of the world.”
“The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one,” Petteri Taalas, Secretary-General of the World Meteorological Organization (WMO) said.
A WMO analysis showed that while measuring 1.2°C above the preindustrial era that 2016 holds the warmest year record, 2017, which measured approximately 1.1° C above the pre-industrial era, was the warmest year without an El Niño, which can boost global annual temperatures.
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.
“We are getting dangerously close to the limit of the 2°C temperature rise set out in the Paris Agreementand the desired goal of 1.5° will be even more difficult to maintain under present levels of greenhouse gas emissions,” he underscored.
Recording the same global average temperatures, 2017 and 2015 were virtually indistinguishable because the difference is less than one hundredth of a degree, which is less than the statistical margin of error.
