Last year's greenhouse gas concentration was the highest ever..."Continue to increase in temperature"

The concentration of greenhouse gases in the atmosphere reached an all-time high last year, and it is predicted that temperature increases will continue for years to come.

The World Meteorological Organization (WMO) announced on the 28th local time that the concentrations of the three major greenhouse gases, carbon dioxide, methane and nitrous oxide, were 420 ppm, 1,934 ppm, and 336 ppm, respectively, last year.

These are equivalent to 151, 265%, and 125%, respectively, compared to pre-industrial times in 1750.

In particular, the concentration of carbon dioxide, which accounts for 64% of climate warming, has increased by more than 10% over the past 20 years.

The WMO explained that the concentration of carbon dioxide increased by more than 2 ppm each year for the 12th consecutive year.

"Last year, land and sea temperatures were the highest since observation in 1850," the WMO said. "Even if carbon dioxide emissions plunge to zero, current temperature levels will continue for decades."

"We are far off the track toward the Paris Agreement goal of curbing the global average temperature increase to 2 degrees Celsius and 1.5 degrees Celsius if possible compared to pre-industrial times," he said.
