Back in the 1970s, we also had 25 years or 30 years. The secular doomsday predictions are as accurate as the ones coming from religious sects and cults.

The Great Drought And Flood (p. 41)
I predict that in the year 1977 the face of the earth will be completely changed. Rain will not fall for a period of ten months. I predict that our great lakes will become beds of sand and rivers will slow down to a trickle. ... The results of this drought will be catastrophic. I predict starvation, disease, insanity and death on an unprecedented scale. Hospitals will be overburdened and the death rate will be so high that the dead will remain unburied for weeks at a time. This will be known as the era of the black death, the twentieth-century black death. I predict that New York City will become a ghost town with industry at a standstill, for power will go dead, subways will be emptied and out of service, and the entire transportation system of this once steaming metropolis will be totally crippled. The populace will leave by the thousands in their search for water. The nation’s highways will be filled with helpless, struggling people.
In the great Midwest, I predict that the dust bowl of Kansas will be the death trap for countless humans and animals. Farms, fields and homesteads will be covered by mountains of sand and dust and no form of life can exist.
