📢 New paper in Biogeosciences! We map contrasting impacts of wet and dry soil moisture extremes on vegetation greenness across the globe. Greenness declines are determined by pre-extreme vegetation conditions and seasonal timings, implying predictability. Read more tinyurl.com/3cmwx8vb

Coinciding browning and drying is found in tropical regions and in eastern Europe, and influence of water-related variables is confirmed with a regression analysis. Earth system models reproduce observation-based results in the multi-model mean, but results from individual models differ strongly.

In this study, we analysed 216 cities around the world and found that trees decrease Universal Thermal Climate Index about 6x more than short vegetation. However, in some regions short vegetation performs similarly. We pinpointed that LST-based measures may overestimate the actual cooling effect.
