In its report, timed for publication just prior to the COP26 U.N. Climate Change Conference, the WMO said that concentration of carbon dioxide (CO2) in the atmosphere “reached 413.2 parts per million in 2020 and is 149% of the pre-industrial level.”
“As long as emissions continue, global temperature will continue to rise,” the WMO warned.
“Alongside rising temperatures, this means more weather extremes including intense heat and rainfall, ice melt, sea-level rise and ocean acidification, accompanied by far-reaching socioeconomic impacts,” it asserted.
“The economic slowdown from COVID-19 did not have any discernible impact on the atmospheric levels of greenhouse gases and their growth rates, although there was a temporary decline in new emissions,” it said.
