Forests make heatwaves initially warmer

During heatwaves forests reduce their evaporation. This causes the atmosphere to warm up even more. During extremely long periods of heat, however, this reduction enables the forests to continue their evaporation for longer, so the net effect is ultimately one of cooling in relation to the surroundings.
