Recent data revealed that the Earth witnessed a rise in carbon dioxide levels in 2020 to their highest levels since the middle of the Pliocene Era 3.6 million years ago. During this prehistoric time period, the sea level was 78 feet higher and it was Earth's temperature is about 7 degrees Fahrenheit warmer than our modern world.
The annual rise in carbon dioxide, 2.6 parts per million, is among the highest recorded since NOAA began tracking more than 60 years ago. The NOAA Global Monitoring Laboratory measured atmospheric levels of the three main greenhouse gases, carbon dioxide, methane, and nitrous oxide, from measurements taken at remote NOAA sampling sites in Hawaii, Alaska, American Samoa, Antarctica, and elsewhere.
The agency did not provide an explanation for the increase, but the effect is likely to be cumulative, and in addition, residential electricity use actually increased during the lockdown.
Since 2000, carbon dioxide has increased in the atmosphere by about 12%, methane has increased in the atmosphere by 6%, and the global average of carbon dioxide has reached 412.5 parts per million in 2020, an increase of 2.6 parts per million from 2019.
Despite an estimated 7% decrease in emissions from the epidemic, this is the fifth-highest increase in 63 years of tracking, and had it not been for the epidemic, the increase would have been the highest ever.
NOAA states that methane is much less abundant in the atmosphere than carbon dioxide, but it is 28 times more efficient at trapping heat.
The agency's preliminary analysis showed that there were 14.7 parts per billion of methane in the atmosphere last year compared to 2019, the largest jump since the agency began measuring in 1983, and the average global methane burden has increased by 119 parts per billion, or 6%, since a year ago. 2000.
