A withered Europe faces what scientists say could be its worst water shortage in the hundreds of years on record. Farms are going fallow, and vineyards are seared. Reservoirs and aquifers have been depleted. Rivers have dried up to reveal Roman-era artifacts and unexploded war munitions. Wildfires have raged across a dozen countries. Scores of small cities and towns are trucking in water because the taps have run dry. … Drought isn’t new to Europe — which has a wide variety of climates and rainfall patterns — and the current one started in 2018. But scientists say human-induced climate change is transforming the continent, raising the likelihood that it will experience more frequent and persistent drought, like the American West.
