However can international warming actually be blamed for these very completely different, remoted occasions in numerous elements of the world?
“Sadly, we’re within the early levels of world warming, and what lies forward can be even worse,” he advised AFP.
“We should not child ourselves that local weather change is proscribed to a couple remoted disasters or to 1 area or time interval.”
In Europe, plenty of air loaded with water have been blocked at excessive altitude by chilly temperatures, main them to stagnate for 4 days over the area and dump torrents of rain, Jouzel mentioned.
“The phenomenon is acquainted to meteorologists, nevertheless it has been 100 years because it final occurred on this scale,” he mentioned.
– Big rainfall – “In simply two days, the area noticed the identical quantity of rainfall it might usually expertise in two or three months — the form of occasion which may generally be seen in Mediterranean climates within the autumn, however not at these latitudes.”
Scientists will now must analyse the occasion to find out exactly why it occurred, he mentioned.
“Science takes time, however I imagine we can have a solution quickly sufficient,” he mentioned.
As as to whether international warming was immediately liable for the disaster, the skilled mentioned: “We have now our suspicions, however they aren’t scientific info. We have now to take the time to analyse the occasion.”
Alternatively, the IPCC has for a while been predicting an intensification of maximum occasions of this type, notably rainfall, he factors out.
“Scientists have already noticed a pointy enhance in excessive precipitation during the last 20 years, notably within the Mediterranean,” he mentioned.
– ‘Less than the duty’ – “It’s clear that if extra water evaporates as a result of it’s hotter, that may technically result in extra precipitation and extra episodes of violent rainfall.”
There’s a actual threat that occasions like this can enhance within the coming years and many years, Jouzel believes.
If the Earth’s temperature rises by three or 4 levels, occasions like droughts, heatwaves and floods will turn out to be extra frequent and intense, he mentioned.
Having the suitable infrastructure to take care of such occasions will then be the one strategy to keep away from human tragedy — such because the devastating results of latest 50 levels Celsius (122 levels Fahrenheit) temperatures in Canada.
“I do not assume there’s sufficient consciousness, and I am unsure that individuals perceive the seriousness of the issue. The political decision-makers, specifically, are lower than the duty,” Jouzel mentioned.
