Because they didn't https://arstechnica.com/science/2016/06/that-70s-myth-did-climate-science-really-call-for-a-coming-ice-age/ But people who obsess about these few instances of cooling-focused press are being a bit selective. It’s not as if the concept of global warming was absent from the 1970s media (or even the 1950s or 1960s media). A 1977 New York Times headline read “Climate Peril May Force Limits on Coal and Oil, Carter Aide Says,” for example. Two years later the same paper ran a story that began, “There is a real possibility that some people now in their infancy will live to a time when the ice at the North Pole will have melted, a change that would cause swift and perhaps catastrophic changes in climate.” And the better stories about aerosol pollution all mentioned the warming influence of CO2 emissions. As for the actual scientific debate about the net effect of aerosols and CO2, it was pretty well settled before the calendar flipped to 1980. Columbia University’s Wally Broecker wrote a 1975 paper (which was also covered in The New York Times) that argued that anthropogenic warming was due to resume; it even correctly estimated the amount of warming we would see before the close of the 20th century. A notable 1978 paper led by NASA’s James Hansen used the 1963 eruption of Mount Agung to refine models of aerosols. And in 1979, the US National Academy of Sciences published a new report chaired by MIT’s Jule Charney. Rather than lamenting our inability to predict climate changes, this landmark “Charney Report” focused on quantifying Earth’s climatic sensitivity to atmospheric CO2. https://www.skepticalscience.com/ice-age-predictions-in-1970s.htm http://journals.ametsoc.org/doi/pdf/10.1175/2008BAMS2370.1 --- Never write off the Doctor! ...
