CAT(0) in Nature

I will briefly recall concepts of CAT curvature, some of its geometric and topological consequences, and then discuss three examples: toric varieties, iterated blowups and ramified coverings. In the first two existence of CAT0 metric is established in some generality, ramified coverings are somewhat problematic, but perhaps most interesting.
