If it’s anyone’s fault it is Jimmy Carter’s. In 1978, he signed the National Climate Program into law to prevent the coming ice age.

“Extreme climatic events in recent years have empha-
sized the central role of climate in human affairs. A series
of droughts, freezes, and other climatic anomalies in many
parts of the world in 1972 caused widespread crop failures.
Large purchases of North American grain by the Soviet
Union and other nations had serious economic repercus-
sions. Severe winter weather in the eastern and midwestern
United States in early 1977 caused many schools, indus-
trial plants, and businesses to close, because not enough
fuel was available for heating. The “Winter of ‘77” also
brought frost damage to the Florida citrus crop and serious
water shortages to drought-stricken regions of the western
United States.”
