Researchers say atmospheric dust in the region has double in the last 20 years, saying the increasingly dry an ar is losing more soil skyward

A brand-new study mirrors dust storms have actually become much more common and more severe on the an excellent Plains, leading some to wonder if the United claims is headed for another Dust Bowl, reports Roland Pease because that Science. Through nearly half the country currently in drought and also a winter forecast predicting ongoing dry weather for countless of the afflicted regions, dust storms could end up being an also bigger threat.

You are watching: Can the dust bowl happen again

In the 1930s, the Dust key was brought about by year of severe drought and also featured dust storms up to 1,000 miles long. But the other driving pressure behind the plumes of dust that devastated the landscape to be the conversion of prairie to farming fields ~ above a substantial scale—between 1925 and also the beforehand 1930s, farmers converted 5.2 million acres of grassland end to farming, reported sarah Zielinski for Smithsonian newspaper in 2012.

Hardy prairie grasses would have likely endured the drought, yet crops spanning the newly converted tracts swiftly bit the proverbial dust, i beg your pardon loosened the grip their roots had actually on the soil. High winds then whipped that loose soil right into the vast clouds that blanketed the landscape with dust, consisting of 1935’s black color Sunday which lifted 300,000 loads of the stuff skyward.

Besides blotting the end the sun, dust storms strip beneficial nutrients indigenous the soils, make the land much less productive, and create a far-ranging health danger at a time when a respiratory condition is sickening people around the world, follow to Science.

The new research, published previously this month in the journal Geophysical research Letters, supplied data indigenous NASA satellites and also ground security systems to detect a steady boost in the quantity of dust being kicked into the setting every year, reports Brooks Hays for United press International. The researchers uncovered that levels of atmospheric dust swirling over the great Plains an ar doubled in between 2000 and 2018.

According to the paper, the enhancing levels the dust, increase to five percent every year, corresponded with worsening climate change and a five to ten percent development of farmland throughout the an excellent Plains that mirrors the prelude to the Dust Bowl. Together, the researchers suggest these components may drive the U.S. Toward a second Dust Bowl.

“We can not make changes to the earth surface there is no some kind of consequence just together we can not burn fossil fuel without consequences,” states Andrew Lambert, a meteorologist at the U.S. Naval study Laboratory and the paper’s very first author, in a statement. “So while the agriculture industry is absolutely important, we need to think more carefully around where and how us plant.”

Part of what permitted Lambert and his colleagues to tie the included dust in the skies to farming were clear local upticks when and also where major crops such as corn and also soybeans to be planted and also harvested, per the statement. Ironically, much of the grassland the was convert to farming in current years was no for food but for corn destined to come to be fodder for biofuels to plan to minimize reliance top top fossil fuels, Lambert speak Science.

Human-caused climate change is likewise making the great Plains hotter and also drier. In April, a document published in the journal Science said the Southwestern component of phibìc America may be beginning a megadrought worse 보다 anything watched in 1,200 years.

“The present drought ranks right up there v the worst in more than a thousands years, and also there’s a person influence on this that at the very least 30 percent and also possibly as lot as 50 percent in terms of its severity,” together Jason Smerdon, a paleoclimatologist at Columbia University’s Lamont Doherty earth Observatory that co-authored the study, told Smithsonian magazine’s Brian Handwerk in ~ the time.

Just critical week, a large dust storm struck eastern Colorado, reports Jesse Sarles for CBS Denver.

“I think it’s fair to say that what’s happening v dust fads in the Midwest and the great Plains is one indicator that the danger is actual if cropland expansion proceeds to take place at this rate and drought hazard does increase because of climate change,” Lambert states in the statement. “Those would be the ingredients for an additional Dust Bowl.”
