A temperature rise of 3°C is unlikely to stop there, even if all activities by humans would stop, including their emissions.
Carbon dioxide at Mauna Loa in June 2022 was 420.99 ppm, a joint record high with May 2022, as illustrated by the above image. Carbon dioxide levels this high are likely to keep adding ocean heat for some time, especially since additional emissions will result from decomposing biomass and fires globally, while the sulfate masking effect will fall away.
In conclusion, temperatures could rise strongly and drive humans into extinction as early as in 2025. Temperatures could continue to rise afterwards, and drive most life on Earth into extinction soon thereafter, making it the more important to do the right thing now and help avoid the worst from happening, through comprehensive and effective action as described in the Climate Plan at:

• NOAA – Trends in Atmospheric Carbon Dioxide – Mauna Loa, Hawaii
