• Temperature response to deforestaAon has strong la8tudinal dependence.
• ∆SW and ∆ET largely determine the impact of deforestaAon.
• Background climate sets constrain to biophysical effects
Summary for the biophysical effects of forest
Forests Evidence Climate model Satellite data
Boreal forest Strong Warming Warming
Northern Temperate forest
Mixed Weak warming Weak cooling
Tropical forest
Strong Cooling Cooling
Considering all the cri8cal roles that forests play in carbon sequestra8on, ecology, biodiversity, society, and regula8ng local climate, forests must be protected.
