I wrote this paper to work how the climate-carbon system could enter a runaway state 👇

Conditions for instability in the climate–carbon cycle system
Abstract. The climate and carbon cycle interact in multiple ways. An increase in carbon dioxide in the atmosphere warms the climate through the greenhouse effect, but also leads to uptake of CO2 by th...

Fascinating new paper from Joe Clarke et al., which addresses the question: could the climate-carbon system suffer a self-sustaining runaway feedback?

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. New Ideas paper from

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.

It's my first day here on Bluesky, and what an excellent way to start with another paper being published.
