New paper finds drought in the US Great Basin was much more extreme in the past
A paper published today in Quaternary Science Reviews finds a severe drought affected the US central Great Basin for almost one thousand years between 2800 and 1850 years ago. According to the authors, this drought was "the longest persistent dry period within the late Holocene." The paper shows modern precipitation levels are not unusually wet or dry, or unprecedented in comparison to the past 8,000 years. The paper adds to hundreds of other peer reviewed publications demonstrating that there is nothing unprecedented, unusual, or unnatural about modern day precipitation, drought, or extreme weather.
