Climate change: When rain, rain won't go away
The Northeast averages about 55 inches of rain and snow annually, according to NOAA records. That's 10% more than just over a century ago.
What's causing the additional rain? It's simple. Warmer air causes more evaporation from streams, lakes and seas. Warmer air also holds more moisture. So, when it falls, it really unloads — thus, more extreme storms.
"Increased extreme precipitation in the Northeast is one of the clearest signals of climate change that we can see nationwide," says climate expert Donald Wuebbles of the University of Illinois in Urbana-Champaign. "It's not just more rain, but more rain falling in buckets over long periods of time."
