In 2020, carbon dioxide levels rose to their highest level since the middle of the Pliocene 3.6 million years ago.
During this prehistoric period, sea levels were about 30 feet higher and the temperature of the earth was about 7 degrees Fahrenheit warmer than our world today.
The 2.6 ppm year-over-year increase in CO2 emissions is one of the highest since the NOAA persecution began more than 60 years ago.
The agency didn’t offer an explanation for the increase, but it was possible the effect was cumulative.
In addition, electricity consumption in the living area actually increased during the lockdown.
Since 2000, atmospheric CO2 has increased by around 12 percent and atmospheric methane by six percent.
Although pandemic lockdowns resulted in a 7 percent decrease in carbon dioxide emissions, the amount of CO2 in the atmosphere actually increased, according to a new report from the National Oceanic and Atmospheric Administration
NOAA’s Global Monitoring Laboratory measured the atmospheric levels of the three leading greenhouse gases – carbon dioxide, methane, and nitrous oxide – from measurements taken at remote NOAA sampling sites in Hawaii, Alaska, American Samoa, the South Pole, and elsewhere.
The global average for carbon dioxide was 412.5 ppm in 2020, an increase of 2.6 ppm from 2019.
Even with an estimated seven percent decrease in emissions caused by the pandemic, this is the fifth highest increase in 63 years of persecution.
Without the pandemic, the increase would have been the highest in history.
According to the NOAA Global Monitoring Laboratory, the average global atmospheric exposure to carbon dioxide has increased by 12 percent since 2000.
Since the beginning of the 21st century, the global CO2 average has risen by 43.5 ppm, or around 12 percent.
“Human activity is driving climate change,” said GML biogeochemist Colm Sweeney.
“If we are to mitigate the worst of the impact, we must consciously focus on reducing fossil fuel emissions to near zero,” said Sweeney.
“And even then, we have to look for ways to further remove greenhouse gases from the atmosphere.”
Methane is far less abundant in the atmosphere than carbon dioxide, but it’s 28 times more efficient at trapping heat, reported NOAA.
The agency’s preliminary analysis found there was 14.7 parts per billion (ppb) more atmospheric methane last year than in 2019, the biggest jump since the agency began measuring in 1983.
Overall, the average global methane exposure has increased by 119 ppb, or 6 percent, since 2000.
That increase is likely due to biological sources like animal husbandry, said GML research chemist Ed Dlugokencky [still] an important step towards mitigating climate change. ‘
The increase in atmospheric nitrous oxide was negligible: from 332.3 ppb in November 2019 to 333.6 ppb in November 2020.
NOAA said while its preliminary estimates are typically slightly higher than final calculations, “the increase through 2020 will likely remain one of the largest on the record.”
According to a January 2021 report by the United Nations Environment Program, the pandemic only caused a brief 7 percent drop in carbon dioxide emissions, which is nowhere near enough to have a significant impact on long-term climate change.
Levels of nitrogen dioxide, a traffic pollutant linked to cancer and respiratory infections, have fallen by 10 to 50 percent worldwide.
After taking into account weather and seasonal trends, the ozone concentration in all cities rose by up to 30 percent according to UNEP findings.
Earlier this week, the Scripps Institution of Oceanography at UC San Diego released findings that atmospheric carbon dioxide levels were 50 percent higher than just before the industrial revolution.
