"CO2 emissions have fallen," the global press said in May 2020, after carbon dioxide emissions were reduced by 17% in April. It has now been shown that the impact of the economic downturn caused by the pandemic in the spring almost around the world was very short to change the dynamics that the world has been dragging on greenhouse gas emissions in recent decades.

The presence of carbon dioxide in the atmosphere of planet Earth this year has exceeded the barrier installed in 2019: The World Meteorological Organization (WMO) has warned that CO2, the main human greenhouse gas, has come to have 417.1 parts per million in the atmosphere, 2.4 more than the previous year. "We surpassed 400 parts per million in 2015 and surpassed 410 parts in four years, at the fastest speed ever seen in the previous records," said WMO Secretary General Petteri Taalás. "Reducing emissions from COVID-19 closures has been a little important in short-term dynamics. We have to bend the curve.

Despite the fact that the year is not yet over, this year it is still unknown to what extent the CO2 concentration will reach, the major weather stations measuring across the globe continue to certify the rise in carbon dioxide, both at the Mauna Loa station in the Hawaiian Islands and in the Australian Tasmania Cape Grim.

The increase in methane by 2020 is not mentioned. It is expected that this gas, of great importance in the weather, will also increase as it did in 2019.

Global records of the gaseous components of the Earth ' s atmosphere have been gathered since 1958. The carbon dioxide level is almost 100 parts higher than then: In 62 years, CO2 has experienced a 31 percent increase in our atmosphere.
