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

How is it possible to own land? The current pattern of ownership and control of land lies at the heart of many of our biggest dysfunctions: the collapse of wildlife and ecosystems, the exclusion and marginalization of so many people, the lack of housing in many cities—indeed, in many parts of the world—the lack of public space in cities, our exclusion from the countryside. The pattern of land ownership underlies all of these massive issues, and indeed of many more. Yet we rarely question it.
