A study published on July 29 showed that human-caused climate change increased the likelihood of a July 2022 heat wave in the UK 10 times. The researchers were also surprised by how quickly temperatures were rising, much faster than models had predicted.

[EN VIDÉO] Global warming: our planet is in an unknown region In the initial version – which covers only the first nine months of 2021 – of its annual State of the Global Climate Report, the World Meteorological Organization (WMO) confirms the global warming trend. For the first time, the elevation bar has been exceeded by 1°C compared to pre-industrial averages over the past 20-year period. But above all, the report highlights the many extreme weather events that occurred in 2021 and their consequences for the planet and for humanity. © World Meteorological Organization
On July 19, the temperature crossed the threshold of 40 degrees Celsius in the United Kingdom, the first in this country that it, like the rest of Western Europe, was hit by an amount heat wave Resulting in fires around London, damaging homes.
An international team of researchers has modeled the probability of such a wave the heat in a pre-industrial climate, and then compare this probability with the current climate, i.e. mean global temperature warming of + 1.2 ° C compared to the pre-industrial period.
They focused on records being set in the hardest-hit parts of the UK, central England and eastern Wales. This probability is shown to be at least 10 times higher with Global Warming.
Extreme temperatures are rising faster than expected
According to this study, extreme events affecting Europe have increased more than predicted by climate models.
“In Europe and other parts of the world, we are seeing more and more record-breaking heat waves, resulting in extreme temperatures, which are increasing faster than most climate models.says Frederic Otto, from Grantham Institute In theImperial College from London. It is a disturbing finding that indicates that if emissions From carbon Not quickly reduced, the consequences climate change In Europe, the extreme temperatures, which are already very deadly, may be worse than expected.”she completes.
