Global temperatures are set to reach a new record high over the next five years and are more than likely to temporarily exceed 1.5C for the first time in human history, the World Meteorological Organization concluded in its latest annual assessment. Has taken out. ,
In their stark conclusion, the scientists said there was a 66 per cent chance for the first time that annual mean global surface temperature rise would temporarily exceed 1.5C and reach 1.8C above pre-industrial levels in “at least” a year . By 2027.
The report stated that “the possibilities were increasing over time”. The 66 per cent assessment of temporarily breaching the 1.5C limit compares with estimates of around 48 per cent a year ago and “close to zero” in 2015.
The report, compiled by researchers from 11 organizations around the world, including Europe, North America, Japan and China, covers the years 2023 to 2027.
The authors said there was a 98 per cent chance that one in five years would exceed the record high temperature rise of 1.28C in 2016, and that the next half-decade would be the warmest on record.
The return of the El Nino weather phenomenon in the Pacific Ocean, which typically raises global temperatures, was expected by the end of this year.
Arctic temperatures were expected to rise three times faster than the global average, as melting snow and ice reduces its ability to reflect back the Sun and causes more warming than anywhere else.
“We are now within reach of a warming of more than 1.5C. . .
Many of the forecasts for the El Niño phenomenon “are showing a very large amplitude of El Niño that we think is developing this winter”, he said.
The warmest year on record occurred in 2016 during an “exceptionally strong” El Niño event.
The opposite weather phenomenon, La Niña, persists for three years, and usually has a cooling effect. Despite this, according to the WMO’s assessment, the eight years from 2015 were likely to be the warmest period on record.
Global temperatures have already risen by at least 1.1C on an average long-term basis. The Paris Agreement commits countries around the world to limit the average increase in temperature to 1.5C, ideally – which is a different measure of the average increase in a given year. Scientists predict that beyond that level of warming, irreversible changes will occur to the planet.
Over the next five years, the researchers estimate that warming in the Arctic will be “disproportionately high”. Leon Hermanson, a senior scientist at the Met Office Hadley Centre, said melting sea ice could mean more shipping lanes open up.
As the planet warms, high-latitude regions in the Northern Hemisphere, such as Scandinavia and Siberia, were expected to experience above-average precipitation between November and March over the next five years, the scientists said.
Meanwhile, between May and September, rainfall was expected to exceed the 1991 to 2020 average over the Sahel region of Africa, northern Europe, Alaska and northern Siberia, but below average over parts of the Amazon and Australia.
All these conditions were “consistent with climate warming”.
