New Nature Ecology & Evolution paper out today @natecoevo.nature.com!

We find that models deviate from observations in the weighting of important soil processes. This mismatch has important implications for developing soil carbon models and improving predictions of soil carbon fate in the future 🌍

New preprint in Earth System Dynamics: When will the northern high latitudes become a net carbon source?

We evaluate using policy relevant SSP scenarios including overshoot, explicitly representing permafrost🌳❄️🔥🏔️

Northern high latitudes could become a net carbon source below 2 °C global warming
Abstract. Under historical warming, terrestrial ecosystems within the northern high latitudes have been a net carbon sink, providing vital mitigation against anthropogenic emissions of CO2. However, t...

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...

NEW – ‘Significant’ risk of Amazon forest dieback if global warming overshoots 1.5C | @ayeshatandon.carbonbrief.org w/ comment from @gergmunday.bsky.social Nico Wunderling @davidamckay.bsky.social David Lapola @chrisd-jones.bsky.social
‘Significant’ risk of Amazon forest dieback if global warming overshoots 1.5C - Carbon Brief
Even passing 1.5C of global warming temporarily would trigger a “significant” risk of Amazon forest “dieback”, says a new study.

Risks of unavoidable impacts on forests at 1.5 °C with and without overshoot - Nature Climate Change
The authors assess the risk of overshoot beyond 1.5 °C warming, using three scenarios with minimal overshoot, brief overshoot and sustained overshoot. They show a risk of long-term Amazon dieback, whi...
