Theyve had to start shutting down nuclear reactors in summer when water levels get too low,
This is a fake news. Period.
Some reactors had to REDUCE THEIR OUTPUT because otherwise they would exceed the temperature increase they're allowed to cause in the river, this to preserve life in the river. No reactor was shutdown because of a low water stream.
What happened last year is a systematic defect was found in an external protection layer, and the decision was made to fix all the reactors having the same potential defect at once. The work took longer than expected, and that caused France having very limited capacity for months, causing worries about power outage.
Not to say it could never happen in the future, but it didn't yet.
Looks like it's happening already. Natural disasters are on the rise, costing billions, insurance companies start bailing out of some area. I was also wondering if international help would come back every year to address a fraction of the wildfire in Canada, Spain, Italy, Greece, and soon pretty much everywhere.
Pretty sure the cost of the disaster is soon going to be unbearable and we'll start abandoning places and infrastructures instead of rebuilding (not officially, of course, we'll just "push back until conditions allow to rebuild" and forget about it as more disasters will occur).
It will be a slow death, though.
