On this day, July 19 in 1976, as drought grips the UK, US scientists are pondering.
“In any market, nervousness reflects uncertainty-and there are few things as uncertain as the weather. “We just can’t confidently predict long-range trends in climate,” says Murray Mitchell, a climatologist at the National Oceanographic and Atmospheric Administration (NOAA) in Washington. Mitchell and other specialists have advanced several theories to explain why droughts occur-and they range from speculation about sunspot cycles to a possible tilting of the earth’s axis. One notion holds that man himself is altering the climate with pollution. By burning fossil fuels, the theory runs, the industrialized world adds carbon dioxide to the atmosphere, creating a “greenhouse effect.” The carbon dioxide traps the sun’s heat, raising temperatures on the earth’s surface. “If we’re still rolling along on fossil fuels by the end of the century,” Mitchell warns, “then we’ve had it.”

Why this matters.
Again, by the late 1970s, we knew enough…
What happened next?
By the late 1970s, the scientific reports were piling up. Carter paid a little attention. Then along came Reagan. And Thatcher…
