Climate change links recent deadly flooding in Eastern Kentucky to the ongoing drought in Arizona. As the Earth warms, its atmosphere can hold more water vapor, but at a slower rate, resulting in fewer, but more powerful, rainstorms. Higher temperatures also mean less snow, which has historically fed many of the American West's rivers and streams, helping to stave off drought. "This has been a slow-motion crisis for two decades now," said Michael Crimmins, professor of climate science at the University of Arizona. "It's just converging at this moment."
