With excessive climate killing greater than 150 individuals in Europe and searing warmth throughout components of North America, the talk round local weather change has grown extra fierce in current weeks.
However can world warming actually be blamed for these very completely different, remoted occasions in numerous components of the world?
In line with Jean Jouzel, a climatologist and former vice-president of the Intergovernmental Panel on Local weather Change (IPCC), there’s a “plausible” hyperlink, although it has not been confirmed but.
“Unfortunately, we are in the early stages of global warming, and what lies ahead will be even worse,” he instructed AFP.
“We must not kid ourselves that climate change is limited to a few isolated disasters or to one region or time period.”
In Europe, lots 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 familiar to meteorologists, but it has been 100 years since it last occurred on this scale,” he mentioned.
“In just two days, the region saw the same amount of rainfall it would normally experience in two or three months — the kind of event that might sometimes be seen in Mediterranean climates in the autumn, but not at these latitudes.”
Scientists will now must analyse the occasion to find out exactly why it occurred, he mentioned.
“Science takes time, but I believe we will have an answer soon enough,” he mentioned.
As as to if world warming was straight answerable for the disaster, the knowledgeable mentioned: “We have our suspicions, but they are not scientific facts. We have to take the time to analyse the event.”
However, the IPCC has for a while been predicting an intensification of utmost occasions of this type, notably rainfall, he factors out.
“Scientists have already observed a sharp increase in extreme precipitation over the last 20 years, particularly in the Mediterranean,” he mentioned.
‘Less than the duty’
“It is clear that if more water evaporates because it is warmer, that will technically lead to more precipitation and more episodes of violent rainfall.”
There’s a actual danger that occasions like this may improve 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 develop into extra frequent and intense, he mentioned.
Having the correct infrastructure to take care of such occasions will then be the one approach to keep away from human tragedy — such because the devastating results of current 50 levels Celsius (122 levels Fahrenheit) temperatures in Canada.
“I don’t think there is enough awareness, and I’m not sure that people understand the seriousness of the problem. The political decision-makers, in particular, are not up to the task,” Jouzel mentioned.
