atmosphere carbon This year, the concentration of carbon dioxide (CO2) will soar to an alarming threshold, exceeding 417 parts per million (ppm), which is a 50% increase since extensive industrial activities began in the 18th century.
The forecast comes from the Met Office, the National Weather Service of the United Kingdom, which uses data collected by the Mauna Loa Observatory in Hawaii.Although due to COVID-19, global greenhouse gas emissions will decrease slightly in 2020 Pandemic And current La Nina Incident (A weather pattern in the Pacific region usually reduces global carbon emissions), not enough to offset previous growth.
Richard Betts, head of the climate impact team of the Metropolitan Office, said: “Because carbon dioxide stays in the atmosphere for a long time, annual emissions have increased compared to previous years, resulting in a continuous increase in the amount of carbon dioxide in the atmosphere “The chief researcher of the forecast, Said in the statement.
The concentration of carbon dioxide in the atmosphere follows predictable seasonal changes. As plants grow and absorb carbon (through photosynthesis) in the northern hemisphere, their levels peak in May, then fall in summer, and then rise again starting in September.
Although the total global carbon dioxide emissions in 2020 will be reduced by 7% compared to previous years, the emissions have almost returned to pre-pandemic levels. According to the Metropolitan Office.
The current La Niña incident has caused unusually cool weather since mid-2020, and it is expected that this year will also reduce the growth rate of carbon dioxide. This is due to the temporary increase in the amount of carbon stored in tropical forests (such as tropical forests), which grow faster in colder conditions.
However, this is not enough to prevent the planet from reaching the ominous carbon dioxide milestone this year.
The Monaroa Observatory maintains the longest continuous record of atmospheric CO2 concentration in the world.
Since climate scientist Charles David Keeling began to make these records in 1958, scientists have used these data to track the level of carbon dioxide in the atmosphere through the Keeling curve, which has become a symbol of the increasing human impact on the global climate system.
This means that we need to do a lot of work to realize that the International Panel on Climate Change will limit global warming to 1.5 degrees Celsius (Above 2.7 degrees Fahrenheit).
Bates said: “Reversing this trend and slowing the emission of carbon dioxide in the atmosphere will require reducing global emissions, and to stop it, global emissions will need to be reduced to zero net value.” “If global warming is limited to 1.5 degrees Celsius, which needs to happen within the next 30 years.”
Metropolitan Office released Carbon dioxide emissions forecast for 2021 January 8.
