While residents of the West Coast of the United States usually don’t have to worry about hurricanes, snow storms, or tornadoes, every winter they do experience extreme weather events known as atmospheric rivers.

However, atmospheric rivers are not all bad; in fact, some might even say they’re essential. They provide up to half of California’s rainfall every year, which is beneficial for agriculture and water supply. Like all weather events, atmospheric rivers are impacted by climate change, so how will they be different in a few decades? This question is essential for water resource managers and regular residents of the West Coast, since atmospheric rivers can both help and harm their livelihoods.Continue reading “Will Atmospheric Rivers Shift from Helpful to Harmful due to Climate Change?”
