Despite the reduction in emissions due to the new coronavirus, the amount of carbon dioxide in the atmosphere is the highest ever recorded

As a result of the new coronavirus infectious disease (COVID-19) that is prevalent in the world, measures such as city blockades and suspension of economic activities were taken in each country, resulting in

global carbon dioxide emissions 17 It has been reported that the percentage has also decreased . However, the results of measurements by the Scripps Institute of Oceanography and the National Oceanic and Atmospheric Administration (NOAA) revealed that in May 2020, the amount of carbon dioxide in the atmosphere was the highest ever recorded.

Scripps Oceanographic Research Institute and NOAA research team said that the data measured at the

Mauna Loa Observatory on the Big Island of Hawaii, 'the atmospheric carbon dioxide amount exceeded 417 ppm in May 2020, the highest ever observed. I recorded it.' In May 2019, the amount of carbon dioxide in the atmosphere was 415ppm, but this announcement has exceeded the record of last year by more than 2ppm.

Carbon dioxide is a major greenhouse gas, and there is an urgent need to stop the increase in carbon dioxide in the atmosphere in order to stop climate change. However, although it was stable at about 280 ppm before the Industrial Revolution, the amount of carbon dioxide in the atmosphere increased as the industry developed around the world and the population increased, exceeding 400 ppm in the 2010s. In the 1960s, the amount of carbon dioxide in the atmosphere was increasing at a rate of 0.8 ppm per year, but since 2010 it is increasing at a rate of 2.4 ppm per year.

Despite the reported reduction in carbon dioxide emissions worldwide from the COVID-19 pandemic, it may seem unnatural that carbon dioxide levels in the atmosphere have reached record highs. But Professor Ralph Keeling of the Scripps Institute of Oceanography said, 'Carbon dioxide buildup is like landfill debris. If we continue to release it, it will continue to build up. Carbon emissions have decreased, but not as much as they appear in the Mauna Loa observatory data.'

The amount of carbon dioxide in the atmosphere fluctuates not only due to human activity, but also due to seasonal activity of plants and the ocean. The record yearly maximum in May is also largely due to the cycle in which carbon dioxide is released from plants and soil from autumn to spring in the northern hemisphere, and plants begin to absorb carbon dioxide in summer. That's right.

Scripps Ocean Research Institute scientists have pointed out that carbon dioxide in the atmosphere over the earth has exceeded 417 ppm for the first time in millions of years. In the days when this level of carbon dioxide was once present in the atmosphere, the average temperature was 2-3 degrees higher than in the present age, and the sea level was 15 to 24 meters higher.

` `The well-understood physics tells us that increasing greenhouse gases are heating the Earth's surface, melting ice, and raising sea levels,'' NOAA scientist Pieter Tans said. 'If we don't stop the rise in greenhouse gases, especially carbon dioxide, much of the earth will become incapable.'
