Vegetation changes and land surface feedbacks drive shifts in local temperatures over Central Asia

Abstract Vegetation changes play a vital role in modifying local temperatures although, until now, the climate feedback effects of vegetation changes are still poorly known and large uncertainties exist, especially over Central Asia. In this study, using remote sensing and re-analysis of existing da...
