Yeah, but what do the Brits know about drought?
The American West is experiencing its worst drought since 800AD - around the time Charlemagne ruled - according to a newly released study.
The ongoing drought has seen lakes, reservoirs and rivers in California fall to record lows, exacerbating wildfires, according to scientists.
The current drought is the worst 22-year dry period in the last 1,200 years - dating back to Vikings and Mayans. The last multi-decade drought occurred in the 1500s, but was not so severe.
The new study published in the journal Nature Climate Change relied on data from the rings in trees and wood beams preserved at Native American archaeological sites.
