I wake groggy from the late arrival of my flood delayed train. Out of habit, I open my phone. Brown water fills the screen, punctured by branches, buildings and the fluorescent jackets of emergency workers. I read a quote from the climate scientist, Sonia Seneviratne, saying that "most of the water vapour came from the Black Sea and Mediterranean Sea, both of which have grown hotter as a result of human-induced climate breakdown". I share the article in our Signal group. Our intern, LJ, replies that this is a "vivid image". I agree, picturing the Mediterranean falling onto Vienna, in an inversion of sky and sea. It is a literal image of our world turning upside down.
