The US detected a record high level of CO2 in the Earth's atmosphere



On June 7, the US National Oceanic and Atmospheric Administration (NOAA) said that the atmospheric research station located in Hawaii has recorded the highest concentration of CO2 since the agency implemented the precise measurement since 1958.

According to NOAA, measured data from the Mauna Loa Observatory in Hawaii shows that atmospheric CO2 concentrations in May 2021 were at an average of 419 parts per million (ppp), up from 417 ppm in May 2020.

The senior scientist at NOAA's Global Monitoring Laboratory, Pieter Tans said that we are adding almost 40 billion cubic tons of CO2 into the atmosphere every year. Extracting resources from the Earth, burning them, and releasing them into the atmosphere year after year If we are to avoid the catastrophe caused by climate change, then the first priority must be to reduce polluting CO2 emissions as soon as possible.

According to NOAA, the COVID-19 pandemic has led many countries around the world to restrict travel and impose blockades and restrictions, with little impact on today's growing emissions of effects.

CO2 is the most man-made greenhouse gas.  Once emitted, CO2 remains in the atmosphere and oceans for thousands of years.  Humans emit CO2 from burning fossil fuels (coal, oil) used in transportation, power generation, construction, deforestation, agriculture...  The greenhouse effect blocks heat radiation from the Earth into space, thus contributing to the warming of the Earth.

Although CO2 concentrations from May 2020 to May 2021 increased by 1.8% from a year earlier, the first five months of this year recorded an average increase of 2.3 ppm, close to the annual increase recorded between 2010 and 2019.

Since May 2013, the concentration of CO2 in the atmosphere has always exceeded 400 ppm.  Current levels are comparable to CO2 concentrations during the so-called Pliocene - the second epoch of the Neogene in the Cenozoic, 4.1-4.5 million years ago.  At that time, sea level was 23.5m above present sea level and the average temperature was 4 degrees Celsius warmer than pre-industrial times, and the large forests once occupied what is now the Arctic tundra.
