In other words, it’s not a single underlying phenomenon — such as El Niño, expected next fall — that would explain these three heat waves. This is an example of the greater likelihood of seeing such heat waves occur, with global warming.
Those in Asia and Europe, which lasted for weeks, broke many records: in Vietnam, the temperature reached 44.2 degrees Celsius. May 7th. Spain recorded the driest April in the 62 years in which such measures were taken. And in southern Spain, temperatures above 40 degrees, generally reached only in June or July, accumulate from the beginning of May.
Moreover, in Europe, there is the historic drought that has hit the region… since the end of 2022.
In western Canada, a heat wave is beginning to set in at the end of last weeknot Not dramatic And there is no indication that it will last that long. But it comes at a time when Alberta is experiencing a series of fires unusually early in the season.
across Southeast Asia (Vietnam, Laos, Myanmar and Thailand), the beginnings are also surprising. temperature records from April Or maybe he was beaten. Thailand even reached its hottest temperature ever on April 15, with 45.4 degrees. Part of India records temperatures three to four degrees above normal.
This entire region traditionally experiences warmer days in the run-up to the rainy season, but the intensity of the heat wave this time around is not typical.
This combined with the fact that it’s almost 45 degrees hot in this area and at this time of year means the temperature is well over 50 degrees, which is the threshold at which it’s dangerous to stay outside for too long. In addition to being disastrous for agriculture in this region of Asia.
On the European side, in Catalonia, water tanks are being filled to 25% of their capacity, a level that the local authorities are making. they said precedent is not known. The summer of 2022 has already been disastrous for and for crops Forest fires. The authorities fear now Repeat this scenario.
The World Weather Attribution, an international consortium of researchers that specializes in connections that can be made between global warming and extreme weather events, qualifies, in a report published May 5, Very unlikely The current Spanish heat wave, if there is no global warming.
It must be remembered that the year 2022 ranked globally, just like the previous years, in the list of the ten hottest years in the century and a half in which such calculations were made, and that the El Niño weather phenomenon, next fallIt should, like its predecessors, result in a small additional boost to global warming.
