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 “precipitously” 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 study’s models. A recent paper examining the original 1972 study goes so far as to say that the study’s predictions are well on course to being borne out.
That research paper, prepared by a University of Melbourne scientist, Graham Turner, is unambiguously titled “Is Global Collapse Imminent?” As you might guess from the title, Dr. Turner is not terribly optimistic.
He is merely the latest researcher to sound alarm bells. Just last month, a revised paper by 19 climate scientists led by James Hansen demonstrates that continued greenhouse-gas emissions will lead to a sea-level rise of several meters in as few as 50 years, increasingly powerful storms and rapid cooling in Europe.
