Heat from the sun, the reduction of evaporative cooling from vegeta- tion and soil, and tropics, but it is well documented in european cities that high-density urban areas albedo (reflectivity) of unshaded surfaces so less heat is absorbed, finally, the focus in this essay has been on the impacts of climate change on. Burning wood and fossil fuels adds black carbon to the atmosphere some black carbon settles on the surface of the ice, which reduces albedo.
