How’s this? “The world must rapidly shift away from burning fossil fuels — the number one cause of the climate crisis. In pathways limiting warming to 1.5 degrees C (2.7 degrees F) with no or limited overshoot just a net 510 GtCO2 can be emitted before carbon dioxide emissions reach net zero in the early 2050s” (see https://www.wri.org/insights/2023-ipcc-ar6-synthesis-report-climate-change-findings#:~:text=The%20world%20must%20rapidly%20shift,zero%20in%20the%20early%202050s.).

However, I remain highly critical of the IPCC for not being much clearer!
