“Last week it was very cold and now we are moving to high temperatures …” The surprise is great in the ski resort of the municipality of Samoens, in Haute-Savoie. While heavy snowfall heralded a good start to the season, the return of rather mild temperatures for this time of year is worrying.
This week, France will never have been so hot for the end of the year. It is expected a temperature of 16.5 ° C over the next two days, five degrees higher than normal. Temperatures are even expected to exceed 20 ° C in the southwest.

“If we postpone it in the middle of summer, it’s called a heat wave”, thus compares Jean-Yves Choplin, forecaster at Météo-France. According to him, these variations would be linked to the oceanic situation of the country. “France, by its situation, is subjected to winters which are very variable. From one week to another, we change completely, and it is usual. So that, it will continue. The only thing that we can say is that we will have milder temperatures more frequently in the middle of winter “, he explains.
Conversely, on the other side of the Atlantic, temperatures have dropped to -50 ° C in Canada. And it is now the entire American West that is affected by this cold wave. In California, for example, nearly five meters of snow fell in December, the highest for that state.
But that could also be good news, according to Andrew Schwartz, director of Berkley’s Central Sierra Snow Laboratery. “Last year our snowfall was among the lowest on record. It led to a severe drought in California.”, he recalls.

In Japan, winter is also intense. There is almost 30 times more snow than normal. In Hikone, in the center of the country, people move between blocked cars and the railroad, which is reputed to be one of the best in the world, failed to weather the storm.
But the most worrying temperatures remain those in Greenland. In recent days, they were twenty to thirty degrees above the seasonal averages. In the Arctic, global warming is three times faster than in the rest of the world.
