Carbon dioxide levels saw a surge in 2020 to the highest since the mid-Pliocene era 3.6 million years ago. During this prehistoric time period, sea level was about 78 feet higher and the Earth s temperature was about 7 degrees Fahrenheit warmer than our modern-day world. The year-over-year rise in CO2, 2.6 parts per million, is one of the highest recorded since NOAA started tracking more than 60 years ago.  The agency didn t offer an explanation for the increase, but its possible the effect was cumulative.  In addition, electricity usage in the residential sector actually increased during lockdown. Since 2000, atmospheric CO2 has risen about 12 percent and atmospheric methane has increased six percent.
