The politico-enviros used to call their scary scenarios "global warming" but who can argue with "climate change"? Weren't we all going to freeze to death based on their weather reports from the '70's?

Global warming is the source of climate change, climate change involves local changes which are not always warming. > Weren't we all going to freeze to death based on their weather reports from the '70's? Short answer: no.

Actually clicking through the links on that page, I find that, where there are full text articles linked, they are sensationalist headlines backed by stories that entirely reflect that global cooling was not generally portrayed, even in the body of those popular media articles, as a likely outcome or scientific consensus, but as one potential outcome of pollution induced climate change. In fact, several of them expressly identify that even then there was a scientific consensus on CO2-driven warming being a current trend, but noting that then-less-understood effects of other pollution forms might, at high enough levels, reverse that and result in radical cooling, even to the extreme of a new ice age. > I lived through the last round of this scare-mongering and remember it first hand. I lived through the time period when the potential of global cooling was being discussed, too, and remember it first-hand. And I remember, despite being rather young, being quite aware that it was a fringe theory, not the scientific consensus, to present it as anything more than one of many possibilities emerging from a then-murky variety of climate evidence pointing in different directions (with warming being the current -- then as now -- secular trend, but some new and not yet well understood factors having been identified that could, in some models, lead to a radical reversal.)
