At a briefing on Earth Day (April 22), representatives of the World Meteorological Organization (WMO) reported that the COVID-19 pandemic would cause the largest reduction in carbon dioxide emissions since World War II, but the reduction will be short-term and will not stop climate change.
WMO expects carbon emissions to fall by 6% this year. However, experts warned that this could be followed by an even higher increase in the rate of greenhouse gas emissions into the atmosphere than before the crisis. In their opinion, the rate of emissions will recover by the middle of next year. To achieve the goals of the 2015 Paris Agreement, it is necessary to reduce the rate of emissions annually by 7%, UN experts emphasized.
They also reported that over 50 years of Earth Day celebrations, the amount of carbon dioxide in the atmosphere increased by 26%, and global temperature rose by an average of 0.86 ° C.
It was also noted that WMO is having difficulty developing climate forecasts, as some aircraft taking special measurements do not fly due to the coronavirus pandemic.
