The World Meteorological Organization (WMO) published the “State of the Global Climate 2021” report, which was prepared using the data from January to September, on the first day of the 26th Conference of the Parties (COP26) of the United Nations Framework Convention on Climate Change (UNFCCC).
According to the report, which was prepared using data from UN agencies, 2016 will remain the hottest year in the 2015-2021 period.
According to the report, greenhouse gas concentrations in the atmosphere reached a new peak last year. With the effect of greenhouse gas concentration on global temperature, the global temperature increase in the January-September period this year was 1.09 degrees Celsius compared to the average temperature in the 1850-1900 period.
The increase in ocean temperature, which has accelerated over the past 20 years, is expected to continue. The ocean absorbs about 23 percent of the annual anthropogenic carbon dioxide emissions in the atmosphere.
Due to climate change, global sea level rose by 2.1 millimeters in 1993-2002, while it rose by 4.4 millimeters in 2013-2021. The rise in sea level was due to rapid melting of the ice sheet.
