- In the early 20th century, farmers across the Great Plains harnessed new technology to cash in on a huge demand for wheat.
- But over-farming led to the removal of prairie grasses which had kept the topsoil in place.
- For years, the region was bombarded by monster dust storms called "black blizzards" that sometimes buried entire houses in grit.
For almost 10 years, the Great Plains became a desert wasteland.
During the 1930s, after an intensive period of over-farming, dust storms regularly wreaked havoc, blanketing towns and farms in grit, destroying crops and making people sick.
The drought and storms led to one of the largest mass migrations in a short period of time in US history.
When it was over, better farming practices were instituted to ensure it never happened again. But even so, in 2020, new research found that the heat waves which caused the dust bowl were more than twice as likely to occur as in the 1930s.
Here's what it was like and why it could happen again.
It all began with wheat. In the late 19th and early 20th century, thousands of farmers moved to the Great Plains, a stretch of arid land once covered in native grasses that stretched across much of middle America from Texas to Montana.

The farmers were enticed by new federal laws to buy land off developers who had divided massive ranches up for farming.
In the following years, they planted millions of acres of wheat and corn.

Demand for crops, wheat in particular, was high in the 1920s due to World War I. Farmers harnessed new technology like tractors to get the most from their land. At the same time, the weather provided the region with plenty of rain.

Until then, prairie grasses had kept topsoil in place, but with all of the intensive farming and over-ploughing, the soil became less stable.

Everything came to a head in the early 1930s when the Great Depression hit alongside a severe drought. Suddenly the demand for wheat had disappeared and the overworked land was ruined.

Up to 2.5 million people left the Great Plains, in one of the country's largest ever mass migrations over a short period of time.
But often, things weren't much better wherever they ended up.
About 200,000 people went to California, where they were treated poorly and called "Okies."

In Iowa the temperature hit 118 degrees in 1934, while Oklahoma, Kansas, South Dakota, and North Dakota all hit 120 degrees in 1936.
Climate scientists have found heat and droughts go hand in hand.
University of Brussels climate scientist Wim Thiery told Yale Environment 360, "Dry soils have this exacerbating effect. There is this positive feedback where dry soils lead to more warmth."
If soil is damp then the moisture evaporates under hot sunlight, but when there's no moisture the land heats up easier, meaning more droughts, which in turn means more heatwaves.

The government's initiatives included federal aid, limiting banks' ability to evict farmers, relief funds, new employment opportunities, buying cattle off farmers.
It also took over millions of acres of land and converted it into carefully monitored grazing districts.

But the drought and the storms continued. In 1935, the "Black Sunday" dust storm hit the High Plains. It rolled across the country to cities on the East Coast and the Atlantic Ocean. It is considered the worst storm of the period.
