This decade the name was changed to "climate change"- which is a more accurate description.

Others have addressed most of these (and the "global cooling" thing is a perfect example of how the media muddies things), but for climate change vs. global warming, the term climate change pre-dates global warming in scientific papers, an the terms address different things. Global warming is the observed phenomenon that the planet is warming long term, climate change is the effects that result.

The correlation isn't the basis though, there's a lot of things that actually lead to a cause/effect relationship, the most basic being basic physics. CO2 is a greenhouse gas, this cannot be debated.
But I get your point, if people think correlation is the only evidence it's far easier to have a space to ignore further evidence. My point was that eventually people have to be accountable for remaining there if they want to continue to maintain an opinion.
