As the Arctic melts, droughts such as the recent 2012–2016 one in California will likely become much more prevalent — owing to the warming of the Arctic leading to the development of high-pressure atmospheric ridges in the Northern Pacific off of the coast of California, which will steer storms towards Canada and Alaska.
While this study was focused entirely on California, the implications have a much broader scope of relevance.
