Denial is about trying to make this about Liberals vs Republicans. When its really about science. The denier theory that “they predicted an ice age in the 70’s”, is not one of their better ones, one of of many they have tried over the years
It falls apart because if you look beyond the links deneirs use which link to just a couple of news stories, look at actual “Sciene” sources and you find even back in the 70’s papers where being published projecting warming, some did look at cooling based on data from the 1940-1970s but data since has shown that was wrong, there was no agreement in the 70s in the science community, denier ave tried to invent it, sadly its pretty easy to show it not true. Of course if deneirs where actually skeptics they would take that step and do the research, that they don’t earns them the title of denier.
