Mont Blanc without freezing cold: zero -degree border rises to exceptional heights in Alps

France moans under extreme heat and the Alps are also not spared. An exceptional measurement confirms that: the zero degree boundary – the minimum height at which the temperature reaches 0 ° C – has risen this weekend to 5.136 meters, a height that has never been observed in June according to Météo France. At the top of Mont Blanc (4,806 meters), normally one of the coldest places in Europe, positive temperatures were measured.
