CARBON DIOXIDE REACHES 420.37 PPM
Mean carbon dioxide (CO₂) at Mauna Loa reached 420.37 parts per million (ppm) in the week from March 27, 2022, higher than it was in any week for millions of years.
The image shows a trend that, if continued, will cross a carbon dioxide level of 450 ppm by 2029.
Add this 450 ppm for CO₂ to 768 ppm CO₂e for methane and the joint CO₂e could be 1218 ppm in 2029, i.e. it would have crossed the point at which the clouds feedback starts to kick in (at 1200 ppm CO₂e).
The clouds feedback could thus raise the global temperature by 8°C by 2029, but when also adding the temperature impact of greenhouse gases and further drivers, the clouds tipping point could be crossed much earlier, say by 2026, while a temperature rise of 10°C could happen even before the clouds tipping point gets reached. Drivers could include nitrous oxide (N₂O), seafloor methane, water vapor, loss of Arctic sea ice and the falling away of the aerosol masking effect, as discussed at the Extinction page.
