Climate scientists and others have in the past few years issued a steady stream of analyses showing that without immediate remedial actions, a disastrous future is headed our way. But is it a four-decade-old study that will prove prescient?
That study, issued in the 1972 book The Limits to Growth, forecast that industrial output would decline early in the 21st century, followed quickly by a rise in death rates due to reduced provision of services and food that would lead to a dramatic decline in world population. To be specific, per capita industrial output was forecast to decline âprecipitouslyâ starting in about 2015.
Well, here we are. Despite years of stagnation following the worst economic crash since the Great Depression, things have not gotten that bad. At least not yet. Although the original authors of The Limits to Growth, led by Donella Meadows, caution against tying their predictions too tightly to a specific year, the actual trends of the past four decades are not far off from the what was predicted by the studyâs models. A recent paper examining the original 1972 study goes so far as to say that the studyâs predictions are well on course to being borne out.
