I notice you offer no explanation for the Great Depression.
As to the dust bowl, yes, a contributing factor to the dustbowl was the extraordinarily high temperatures of the mid 1930s before those temperatures were “corrected” by NASA/NOAA.
Some guy compares the previously published temperature records to the “corrected” numbers in a gif shown at the link.
The fall in exports following Smoot-Hawley occurred during 1930-1932.
Temperatures rose during the same period, and remained extraordinarily high for several years. 1936 (well into the Great Depression) was the worst year of the heat wave.

The loss of export markets and the heat wave were a double whammy hitting the farmers of the country. But, the fall in farm income coincided with the fall in exports. Farm income actually stared recovering by 1934.

By the mid 1930s the worst of the heat wave was upon us. It was like the second of a one-two punch combination.
“I notice you offer no explanation for the Great Depression.”
The explanation is FDR. He turned a recession into a depression with his commie BS.
