Alkama och Cescatti combine satellite measurements of air temperature with high-resolution ground images that show changes in forest cover all over the world. By measuring the temperature close to places where forests are cleared or restored, a fine-grained picture emerges. Deforestation increases temperature, more so in arid areas than in boreal parts of the world. An intact forest cover reduces daily variation in temperature and can therefore mitigate local effects of climate change. Read the whole article in Science.
