Crossing a climate tipping point doesn't mean tipping is inevitable - a threshold can be temporarily passed if overshoot is short-lived.
Limiting time over 1.5 °C would considerably reduce tipping point risks.

ESD Ideas: Climate tipping is not instantaneous – the duration of an overshoot matters
Abstract. Climate tipping points are not committed to occur automatically upon crossing critical thresholds in global warming, as is often assumed. Instead, it is possible to temporarily overshoot a t...

New paper in ESD (esd.copernicus.org/articles/16/...) showing duration of overshoot matters for preventing climate systems from tipping. Crossing a tipping point does not equal tipping. Risk reduced if overshoot duration beyond 1.5 °C kept below a century. @coxypm.bsky.social @gsiexeter.bsky.social
