Extended Data Fig. 4: Change in groundwater temperatures following SSP5-8.5, 25th and 75th percentile projections.

a and d, Map of the change in annual mean temperature between 2000 and 2100 following SSP5-8.5 at the depth of the water table (under consideration of its seasonal variation). Temperatures in 2000 are based on the historic CMIP6 scenario. The line in the legend indicates 0 ∘C. b and e, Annual mean groundwater temperature 5 m below the surface. c and f, Annual mean groundwater temperature 30 m below the surface. a to c, Annual mean groundwater temperature 25th percentile projected changes. d to f, Annual mean groundwater temperature 75th percentile projected changes.
