Deforestation-induced surface warming is influenced by the fragmentation and spatial extent of forest loss in Maritime Southeast Asia

Tropical deforestation accelerates local warming and loss of safe outdoor working hours

“…The magnitude of deforestation-associated warming reported here (Figure 1B) and elsewhere 12,13,29 has implications for economic impacts of labor lost 45,64 and raises questions about long-term adaptation to global warming for these hard-hit regions. Beyond the possible downstream health impacts outlined above, local warming exacerbated by deforestation may have implications for migration, 65,66 economic production, 67,68 and human capital.…”

“…A growing body of work has highlighted how deforestation is associated with local warming, particularly at low latitudes. 9,12,13,28,29 Our results suggest warming from tropical deforestation may already impact outdoor workers through the loss of safe work hours across the tropics, and this impact will be exacerbated by future warming and possible increases in deforestation. Specifically, humid heat exposure, as measured by HI or wet bulb globe temperature (WBGT), is expected to increase as the globe warms, 46,51 which will have implications for productivity of both agricultural workers, crops, 77 and livestock, 78 as well as the intensity of heat waves and associated heat stress in the tropics and subtropics.…”

“…[21][22][23][24][25][26]27 Studies on deforestation and temperature changes have focused on quantifying warming from tropical deforestation at regional scales, 13,28 and the relationship between deforestation and increasing temperatures in the tropics is well established. 4,[7][8][9][10][11]29,30 However, only a few small-scale studies have evaluated deforestation effects on heat exposure and the wellbeing of nearby populations in rural communities, 8,31,32 limiting our understanding of whether these effects extend globally in similar settings across low-latitude countries.…”

Satellite-Derived Land Surface Temperature Dynamics in the Context of Global Change—A Review

“…In the Amazonas region, LST increases due to deforestation have been reported from Xinga, Brazil [38], and Caatinga, Brazil [36]. In South East Asia, increased LST could be measured up to 6 km away from the forest disturbance site [33]. In Brazil, increases in maximum LST due to forest loss were noticed even within a 50 km distance [32].…”

“…Figure 1 provides an overview of the application fields of LST. LST has been used to study global warming [3][4][5][6][7][8][9][10][11][12][13][14][15][16], interannual climate variabilities [5,[7][8][9][10]14,17], heat waves [18][19][20], droughts [21][22][23][24][25], soil moisture dynamics [22,23,[26][27][28][29], forest dynamics [28,[30][31][32][33][34][35][36][37][38][39], general vegetation-temperature interactions [15,20,[24]…”
