one comment from one of many samples:
I was writing about science in the 1970s. I wrote then about the predicted "global cooling trend." It was predicted, sure, but it was based on scientists' confirmation and new understanding of Milankovitch cycles, which are astronomical cycles, and which appear to combine to create the coming and going of ice ages.
So ... yes ... in the 1970s, scientists were predicting a coming ice age. That was a big deal back then, to be able to predict that. But the ice age was predicted to come in about 10,000 years. Not immediately.
At the same time, in the 1970s, some scientists were already discussing global warming as a real possibility for the immediate future.
So there's been no shift in scientists' opinions. Those who suggest such a shift are distorting history. There's been only increasing understanding - a steady progression of understanding - about the seriousness of global warming in 21st century and beyond.
