According to a recent study, the 1934s drought that helped outset the Dust Bowl era was the pits to hit North America for the past 1,000 year.
Recently, the NASA’s researchers together with Columbia University’s Lamont-Doherty Earth Observatory renovated the history of droughts in the United States with the help of contemporary practices and tree-ring records from the years 1000 to 2005.
The scientists found that the 1934 drought covered more than 70% of western North America and was 30% severer than the next worst, which struck in 1580.
Ben Cook, study lead author and a climate scientist at NASA’s Goddard Institute for Space Studies in New York stated, “It was the worst by a large margin, falling pretty far outside the normal range of variability that we see in the record.”
He further stated that, a high-pressure system during the west coast’s winter that kept raining at bay, combined with poor land management practices, led to dust storms in the spring.
The study is due to be published in the 17th Oct edition of Geophysical Research Letters.
