Land cover changes can impact the climate by influencing the surface  energy and water balance. Naturally treeless or sparsely treed peatlands were extensively  drained to stimulate forest growth in Finland over the second half  of 20th century. The aim of this study is to investigate the  biogeophysical effects of peatland forestation on regional climate in  Finland. Two sets of 18-year climate simulations were done with the  regional climate model REMO by using land cover data based on  pre-drainage (1920s) and post-drainage (2000s) Finnish national  forest inventories.  In the most intensive peatland forestation area, located in the middle west of Finland, the results show a warming in April of up to 0.43 K in  monthly-averaged daily mean 2 m air temperature, whereas a slight  cooling from May to October of less than 0.1 K in general is found.  Consequently, snow clearance days over that area  are advanced up to 5 days in the mean of 15 years. No clear  signal is found for precipitation. Through analysing the simulated  temperature and energy balance terms, as well as snow depth over  five selected subregions, a positive feedback induced by peatland  forestation is found between decreased surface albedo and increased  surface air temperature in the snow-melting period. Our modelled  results show good qualitative agreements with the observational  data. In general, decreased surface albedo in the snow-melting period and  increased evapotranspiration in the growing period are the most  important biogeophysical aspects induced by peatland forestation  that cause changes in climate. The results from this study can be further integrally analysed with biogeochemical effects of peatland forestation  to provide background information for adapting future forest management to mitigate climate warming effects. Moreover, they  provide insights about the impacts of projected forestation of tundra at high latitudes due to climate change
