The annual peak of global heat-trapping carbon dioxide in the air has reached another dangerous milestone. which is 50% higher than the industrial age

And the average rate of increase is faster than ever. Scientists reported on Monday.

The National Oceanic and Atmospheric Administration said average carbon dioxide levels for May were 419.13 parts per million, NOAA climate scientist Pieter Tans said was 1.82 parts per million higher than May 2020. and 50% higher than pre-industrial stable level.

Carbon dioxide levels peak every May. Before the vegetation in the northern hemisphere bloomed It sucks some of the carbon out of the atmosphere and into flowers, leaves, seeds and stems. However, the relief is temporary. This is because the CO2 emissions from burning coal, oil and natural gas for transportation and electricity are beyond what plants can handle. As a result, greenhouse gas levels set new records every year.

Natalie Mahowald, a climate scientist at Cornell University. which was not part of the research said. “Access to CO2 that is 50% higher than pre-industrial times sets a new standard. and not in a good way.” “If we want to avoid the worst effects of climate change, We have to work a lot harder to reduce our carbon footprint and immediately.”

Climate change is more than just increasing temperatures. Studies show that bad weather, such as storms, wildfires, floods and droughts, are worse and more frequent. and make the oceans higher and more acidic. It also has health effects. including increased deaths from heat and pollen. In 2015, countries signed the Paris Agreement to try to keep climate change below dangerous levels.

Ralph Keeling, a geologist at the Scripps Institution of Oceanography, said Keeling’s father began monitoring carbon dioxide atop Hawaii’s Mauna Loa in 1958, and he continues to chart the now-famous Keeling Curve.

Scripps, which calculates numbers slightly differently by time and mean It said the highest point in May was 418.9.

The epidemic lockdown has also slowed transport, travel and other activities by about 7 percent, previous studies have shown. But that’s too small to make a significant difference. Carbon dioxide can remain in the air for 1,000 years or more. Therefore, the change in emissions from year to year is not much.

The 10-year average increase has also set a record high, now reaching 2.4 parts per million per year.

“Carbon dioxide will increase over the next few decades. which is extremely unusual,” Tans said. For example, when Earth climbed out of the last ice age, Carbon dioxide increases by about 80 parts per million. and use the world system It’s a 6,000-year-old natural system. We’ve had a huge increase over the last few decades.”

By comparison, it took only 42 years from 1979 to 2021 to add the same amount of CO2.

Michael Oppenheimer, a Princeton University climate scientist. , which was not part of the research, said the world was approaching a point beyond Paris and entering the climate danger zone was inevitable.
