Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe

Residents of an Indonesian island threatened by rising sea levels have begun legal action against the cement producer Holcim. The claim for compensation, filed in Switzerland by three men and one woman, is understood to be the first major climate damages lawsuit against a cement company.
47 major emitting companies could be found liable for human rights violations arising from climate change. It also claimed that companies which had obstructed evidence or deceived the public about the link between emissions and climate change could be liable under criminal laws. How likely any of these companies or states are to pay damages will depend on how courts respond.
Experts say scientific advances are making it easier to attribute the damages of climate breakdown to companies’ activities. Businesses could soon be facing a fresh wave of legal action holding them to account for their greenhouse gas emissions, owing to advances in climate science, experts have warned.
In our latest study, scientists from France, Germany, Netherlands, and the UK collaborated to examine whether and to what extent human-induced climate change had a part to play in the cold early April following a very warm March 2021 that led to large scale frost damages in grapevines and fruit trees in central France.
