Hot without end

Heat alert: why it’s so tropical in Vienna

Vienna is currently being hit by a heatwave. The whole city is sweating and groaning under oven temperatures. No wonder, because the federal capital is disproportionately affected by the heat. Even at night, it feels like it hardly cools down at all. And the worst could be yet to come.
