Past 7 years are on track to be warmest on record: Report

Baku, November 1, AZERTAC

The past seven years are on track to be the warmest on record, with the global sea level rise accelerating since 2013 to a new high in 2021, the World Meteorological Organization (WMO)'s latest report revealed on Sunday, according to Anadolu Agency.
The WMO released its provisional report on the State of the Global Climate 2021 on the opening day of the 26th session of the Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change, which will be held in Glasgow, Scotland, until Nov. 12.
Combining input from multiple UN agencies, national meteorological and hydrological services, and scientific experts, the report said this year witnessed an early temporary cooling event, but this did not negate or reverse the long-term trend of rising temperatures.
"The report draws from the latest scientific evidence to show how our planet is changing before our eyes. From the ocean depths to mountain tops, from melting glaciers to relentless extreme weather events, ecosystems and communities around the globe are being devastated," UN Secretary-General Antonio Guterres said in the report. "COP26 must be a turning point for people and the planet."
He said the scientists are clear on the facts. "Now leaders need to be just as clear in their actions. The door is open and the solutions are there. COP26 must be a turning point. We must act now with ambition and solidarity to safeguard our future and save humanity," he urged.
Greenhouse gas concentrations reached new highs in 2020, the WMO report revealed.
Levels of carbon dioxide (CO2) were 413.2 parts per million (ppm) by increasing 149% compared to the pre-industrial (1,750) levels.
The levels of methane (CH4) were at 1,889 parts per billion (ppb) and nitrous oxide (N2O) at 333.2 ppb, 262% and 123% higher than pre-industrial levels, respectively.
The global mean temperature for 2021 was about 1.09 degrees Celsius above the 1850-1900 average based on data from January to September, indicating that the trend has continued, according to the report.
The six datasets used by the WMO in the report placed 2021 as the sixth or seventh warmest year on record globally. However, the report said, the ranking may change at the end of the year.
The year 2016 remained the warmest year on record in most of the datasets analyzed.
"Extreme events are the new norm. There is mounting scientific evidence that some of these bear the footprint of human-induced climate change," WMO Secretary-General Petteri Taalas said.
He warned that the current rate of increase in greenhouse gas emissions would result in a temperature rise of more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels by 2100, exceeding the Paris Agreement targets of 1.5 degrees Celsius.
"COP26 is a make-or-break opportunity to put us back on track," Taalas said.
