Heatwaves are intensifying with longer durations, and different climate scenarios suggest that more people will be exposed. Please read our latest work led by Adeyeri Oluwafemi. The article is freely and publicly available. https://t.co/rL9HS2oiM5

We generated high-resolution GRACE data to map drought-affected areas and quantify drought deficits in the Nile Basin. We continue to explore ways to make GRACE more operational for practitioners. The article below is freely and available. https://t.co/pNtEZxCmYi
