Swiss glaciers are losing fast-protecting snow as Europe bakes in a heatwave. That risks bigger ice loss later. Reports tell the story. In the United States, analysts say the current hot spell would not occur without climate change. Homes in the region still can’t cope with extreme heat. Take older cities - older flats there stay hot without air conditioning. Locals step up on food shocks. Governments lag behind in response. These signs show heat danger rising and preparedness lagging everywhere.
