🌳Global Forest Watch’ analysis of #TreeCoverLoss data from @umd_glad reveals the tropics saw an unprecedented level of fires in 2024. We cannot afford to ignore the 2024 wake-up call 👉 go.wri.org/tree-cover-los…

Prof Matthew Hansen Department of Geographical Sciences UMD GLAD described the new results as frightening & warned of possible "savannisation" of the rainforest, where old-growth tropical forests die back & switch to savanna "It's a theory, but more & more plausible." bbc.co.uk/news/articles/…

Prof Peter Potapov UMD GLAD Department of Geographical Sciences “2024 was worst year for fire-driven forest loss. If it continues, it could permanently transform critical natural areas & unleash large amounts of carbon – intensifying climate change & extreme fires" theguardian.com/environment/20…

🚨 New CEOS LPV Global Land Cover Validation Guidelines! 🌍 Congratulations to UMD GLAD Department of Geographical Sciences researchers A. Tyukavina, A. Komarova, X.-P. Song, A. Pickens, P. Potapov & M. Hansen for key contributions. Read here 👉 doi.org/10.5067/doc/ce… #LandCover #RemoteSensing

🚀 Just released: updated Land Cover Map Validation Guidelines led by UMD GLAD's Alexandra (Sasha) Tyukavina. These best practices help researchers & practitioners worldwide build more accurate, reliable land cover maps. Free & open to use. go.umd.edu/land-cover-map…

❓Why would a scientist who tracks forests speak out about political AI? 🤖 UMD GLAD's Andres Hernandez-Serna Andres Hernandez-Serna. warns: the AI that maps forests is now shaping political messages without labels or accountability. Learn more: go.umd.edu/political-ai-c…
