However, the crucial role of the strengthening of the Indian summer monsoon and future warming on dwindling groundwater storage in north India remains unexplored. Using in situ groundwater observations and model simulations, we show that during 2002–2022, about 95% of groundwater loss (∼498 km³) from India occurred from north India (∼472 km³), a global groundwater depletion hotspot. Well observations show a more robust coupling with climate through rainfall variability. Groundwater loss is driven by excessive pumping from nonrenewable groundwater storage and will continue to dominate in the near future despite projected increases in rainfall (∼4%–6%). The highest projected groundwater recovery (258.9 ± 171.6 km³) in the near period (2021–2040) is only about half of the total groundwater loss. Therefore, increased rainfall may not help recover the lost groundwater.trueclimate change | climate models | global warming | groundwater depletion | groundwater pumping | groundwater recovery | hydrological modeling | Indian monsoon rainfall | irrigation | nonrenewable groundwaterArticle25903322419-42721 April 202314arJournal11WOS:000999727000001
