Greenhouse gases hit record high

By Phil Bainbridge

October 26, 2021 - Greenhouse gases in the atmosphere rose to record levels in 2020 despite a decrease in new emissions due to the pandemic, jeopardizing the effort to cap rising temperatures.

The concentration of carbon dioxide, which accounts for around 66% of the heating effect of greenhouse gases, reached 413.2 parts per million in 2020, 149% of the pre-industrial level. Despite the economic slowdown and reduced industrial activity caused by COVID-19, there was no discernible impact on the atmospheric levels of greenhouse gases and their growth rates, although there was a decline in new emissions.
