We're proud to see Jared Lewis in Japan last week helping launch something the climate community has been talking about for years. The #RapidEvaluationFramework (REF) is now live, built to track how c...

Abstract. Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation...

A scientific foundation is required to establish nations’ responsibilities in a hotter ‘overshoot’ world.

Carbon dioxide removal (CDR) options are critical for achieving global climate objectives. Yet, many proposed removal technologies are in their formative phase. Significant near-term investments ar...

It is important to understand how much long-term sea-level rise is already committed due to historical and near-term emissions. Here the authors use a modelling framework to show how decisions on glob...

The first-ever international conference on the contentious topic of “overshoot” was held last week in...

As global temperatures approach the 1.5°C threshold, understanding the risks of climate overshoot has become an urgent scientific and policy challenge. From 30 September to 2 October 2025, IIASA will ...

A risk-based, spatially explicit analysis of carbon storage in sedimentary basins establishes a prudent planetary limit of around 1,460 Gt of geological carbon storage, which requires making explicit ...

Causal pathway from AMOC to Southern Amazon rainforest indicates stabilising interaction between two climate tipping elements, Högner, Annika, Di Capua, Giorgia, Donges, Jonathan F, Donner, Reik V, Feulner, Georg, Wunderling, Nico

In this report we explore who could pay for loss and damage through the lens of responsibility for historic emissions, and the financial gains generated from selling oil and gas.

How mountain glaciers will react to temporarily overshooting 1.5 °C of warming is poorly understood. Here the authors show irreversible global glacier loss for centuries after overshoot, implying long...

Klima ist Gegenstand des Koalitionsvertrags zwischen CDU und SPD, Klimaschutz weniger. Was fehlt? Der Klimaforscher Car-Friedrich Schleussner erklärt, wo es Lücken und Widersprüche gibt.

Although the climate goals set by the Paris Agreement are based on the long-term average temperature, one year of high temperatures might be a sign that the 1.5°C threshold has already been reached

What a first year with temperature 1.5 °C above the pre-industrial baseline implies for long-term temperature goals is unclear. Here the authors show that such a first year above the baseline is highl...

Kli­ma­wis­sen­schaft­le­r*in­nen sind sich uneinig, ob das 1,5-Grad-Ziel noch taugt. Woran man Klima-Erfolge und globale Gerechtigkeit messen kann.

Providing actionable climate information requires an end-user focused approach that links specific local climate risk thresholds with global emissions pathways.

Aiming for declining global temperatures can limit long-term climate risks compared with a mere stabilization of global warming, including sea-level rise and cryosphere changes.
