CARBON DIOXIDE LEVELS KEEP ACCELERATING

Current CO₂ levels far exceed levels that were common during the past 800,000 years. Peak levels over the past 800,000 years were about 280 ppm.

The May 3, 2019, CO₂ level recorded by scripps.ucsd.edu at Mauna Loa, Hawaii, was 415.09 ppm. Greenhouse gas levels this high correspond with a 10°C or 18°F higher temperature than temperatures that were common in 1750.

Indeed, a 10°C or 18°F rise in temperature from preindustrial is in line with such high greenhouse gas levels, as described in the earlier post 'What Does Abrupt Climate Change Look Like?'

In fact, abrupt warming could result in a rise of 18°C or 32.4°F by 2026, as described in a recent post.
