Climate Change: Annual greenhouse gas indexÄr politiker inkompetenta halvfigurer som går i fossilindustrins ledband?
"By the end of 2019, the warming influence of human-produced greenhouse gases had risen 45 percent above the 1990 baseline."

NOAA's Annual Greenhouse Gas Index–
• The AGGI in 2019 was 1.45, which means that we’ve turned up the warming influence by 45% since 1990.
• It took ~240 years for the AGGI to go from 0 to 1, i.e., to reach 100%, and 29 years for it to increase by another 45%.
• In terms of CO2 equivalents, the atmosphere in 2019 contained 500 ppm, of which 410 is CO2 alone. The rest comes from other gases.
• CO2 is by far the largest contributor to the AGGI in terms of both amount and rate of increase.
• Note: The IPCC suggests that a constant concentration of CO2 alone at 550 ppm would lead to an average increase in Earth’s temperature of ~3°C (5.4°F).
