This is a great video series (currently only 4 videos long) that covers the history of climate science, the debate in the scientific community (yes it exists but it is very minimal, with the overwhelming majority of scientists supporting AGW, hence the consensus), and some popular myths.
What is the difference between “global warming” and “climate change”?
In most writings both terms can be (and indeed are) used interchangeably.
See here for more.
I see: Broader … and vaguer. Therefore, more palatable, presumably. Like “choice,” “affirmative action,” “revenue raisers,” “fairness doctrine,” “hate speech laws,” etc.
Climate change is vaguer than global warming, and perhaps more palatable. Frank Luntz advised the Bush administration to use the term climate change instead of global warming, because it according to his research the climate change sounded like a less urgent issue.
When I started blogging I predominantly started using the term climate change, because that the term that much (but certainly not all) of the scientific literature uses, and is what most of my profs in school used. However I switched to predominately using global warming because I read several articles saying that global warming would result in more visitors through Google and other search engines.
A rose by any other name would smell just as sweet.
