@unep.org outlines the impact of repeated government failures to cut GHG emissions in line with the Paris Agreement There are no good outcomes in overshooting and staying above 1.5°C, only enormous risks Massive near-term emissions reductions are now needed to limit overshoot extent and duration

If you want 1.5C, 1.8C, 2C, overshoot, no-overshoot, etc, then they all require the same thing: rapid short-term emission reductions reaching net zero CO2 emissions as soon as possible. This has been clear from the IPCC Special Report on 1.5C, which depicts "overshoot" on its cover! 1/
