It’s a wonder we’re all not dead. If half the failed predictions had come true, we would be. Undoubtedly some of the predictors think we should be. From Peter Svab at theepochtimes.com:
Newspaper clippings documenting the predictions were recently published by the Competitive Enterprise Institute, a conservative think tank. Many of those were first collected by geologist and electrical engineer Tony Heller, who frequently criticizes—on his RealClimateScience.com website—what he considers fraud in the current mainstream climate research.
The predictions, some going as far back as 1930s, not only at times contradict each other, but sometimes foretell the same imminent catastrophe repeatedly for years, even decades, seemingly undeterred by past failures.
