Hundreds are dead in Spain's floods. Scientists see a connection to climate change

At least 205 people are dead, and dozens remain missing after flood waters and mud swept through towns and cities in Spain’s east.
It’s one of the most deadly weather events in modern Spanish history, and climate scientists see a connection to human-caused global warming.
Climate change made this week’s intense rainfall about 12% heavier and twice as likely, according to a rapid analysis by
World Weather Attribution, an international network of scientists who assess the impact of climate change on major weather events.
“There is a clear climate change footprint on events like this one,”
Daniel Swain, a climate scientist at UCLA who was not involved in the analysis, writes in an email.
For decades, climate scientists have warned that global warming, which is primarily caused by humans burning oil, gas and coal, would cause severe deluges.
An atmosphere made hotter by burning fossil fuels can hold more water vapor, which can make downpours more intense. The world is now at least
1.3 degrees Celsius (2.3 degrees Fahrenheit) warmer than it was during the 1800s.
Climate research finds a 1.3 degree temperature increase means the atmosphere can hold about 9% more moisture.
In places like Chiva, a town near Valencia,
a year’s worth of rain fell in just eight hours, according to ...
