Our satellite radar based damage map of Gaza is on the front page of the New York Times today. This is the result of a collaboration with @coreymaps and @wallacetim to document the effects of the war across all of Gaza every 5-6 days.

on a new paper, we measure just how much greenhouse gas (GHG) is released when drought visits dams, strips away their water, exposes the soil underneath, and then rewets the soil. important since drought frequency and intensity are expected to increase.

With that -- here's to the end of war. The end of needing to detect war. The end of forced displacement. The end of disfigurement and death. The end of war's toxic environmental legacy. The end of toxic masculinity that drives war. The end of imperialism. ✌️🛰️✌️ /15
