The United Nations Meteorological Body said on Wednesday that the record greenhouse gas levels helped bring the temperature to a high level of all time, accelerating the loss of glacier and sea ice, raised the sea level and brought the world closer to an important warming threshold.
The World Meteorological Organization (WMO) said in its annual climate report that the annual average temperature was above 1.55 ° C from pre-industrial levels last year, last year before 0.1 ° C from pre-industrial levels, crossing the previous 2023 records.
The countries agreed in the 2015 Paris Agreement that an attempt should be made to limit the increase in temperature within 1.5 ° C above the 1850–1900 average.
The WMO stated that the initial estimates closed the current long-term average growth between 1.34 ° C-121 ° C, but the Paris is not yet more than the threshold, WMO said.
John Kennedy, a scientist of WMO and prominent writer of the report, said, “One thing to indicate very clearly is that a single year above 1.5 degrees does not mean that the level mentioned in the Paris Agreement was formally higher.”
But uncertainty in data means that it cannot be dismissed, he said during a briefing.
The report stated that other factors may have increased global temperature last year, including changes in the solar cycle, a large -scale volcanic explosion, and a decrease in cold aerosols.
While the low number of areas saw a drop in temperature, extreme weather wreaked havoc worldwide, lack of food due to drought and flood and forest fire forced to displace 800,000 people, most ever since the records started in 2008.
The heat of the ocean also reached its highest on record and the rate of warming is accelerating, increasing the level of acidication even with increasing oceans CO2 concentrations.
The glaciers and sea ice kept melting at a rapid rate, which in turn pushed the sea level to a new high level. From 2015 to 2024, the sea level has risen an average of 4.7 mm per year as compared to 2.1 mm from 1993 to 2002, showing the WMO data.
Kennedy also warned of long -term implications of melting ice in Arctic and Antarctic regions.
“Changes in areas can potentially affect the overall circulation of oceans that affect climate around the world,” he said. “What happens in the stick is not necessarily not on the sticks.”
