Europe’s rivers are drying up.
In places, the Loire can now be crossed on foot; France’s longest river has never flowed so slowly. The Rhine is fast becoming impassable to barge traffic. In Italy, the Po is 2 metres lower than normal, crippling crops. Serbia is dredging the Danube.
Across Europe, drought is reducing once-mighty rivers to trickles, with potentially dramatic consequences for industry, freight, energy and food production – just as supply shortages and price rises due to Russia’s invasion of Ukraine bite.
Ok but it’s only industry, freight, energy and food production. Everything else is ok.
With no significant rainfall recorded for almost two months across western, central and southern Europe and none forecast in the near future, meteorologists say the drought could become the continent’s worst in more than 500 years.

France’s rivers might not be such key freight arteries, but they do serve to cool the nuclear plants that produce 70% of the country’s electricity. As prices hit all-time highs, power giant EDF has been forced to reduce output because of the drought.
Strict rules regulate how far nuclear plants can raise river temperatures when they discharge cooling water – and if record low water levels and high air temperatures mean the river is already overheated, they have no option but to cut output. With Europe’s looming energy crisis mounting and the Garonne, Rhône and Loire rivers already too warm to allow cooling water to be discharged, the French nuclear regulator last week allowed five plants to temporarily break the rules.
I.e. it allowed already overheated rivers to become even more overheated. We’re trapped in this loop.
Rice production that depends on the Po has crashed.
In the protected wetlands of the river’s delta, near Venice, its high temperature and sluggish flow have reduced the water’s oxygen content to the extent that an estimated 30% of clams growing in the lagoon have already been killed off.
Loop. Trapped.
