Glaciers are melting in Europe. Alpine valleys that have been blocked by rivers of ice for as long as anyone can remember are now passable on foot. This is due to the maleficent influence of human activity, we hear: in particular, due to humans of the gas-guzzling American entrepreneurial capitalist white male sort.
