And yet, that sounds like an insignificant error, ie, the mislabeling of an individual.Just offhand, without checking?
About two weeks ago I was reading a Wiki article about climate change deniers. where the author was accusing one man of being an absolute denier. The quote referenced, however, was this man saying that the earth changes climate constantly; that humans are NOT completely responsible for it, but that we can and do make things worse. He went on to illustrate the power of humans to screw things up (and to fix them) by referring to the hole in the ozone layer (remember that? It's still up there) that was caused by human activity...and then when the cause was discovered, banning fluorocarbons globally not only stopped the growth of the hole, it's shrinking and will be gone by the end of the century.
Not exactly the stance of a 'climate change denier.'
.....and it would be, I think, important to any conversation about climate change, I think, casual or not.
So...I check the references.
Mostly.
Now, if the discussion were about that individual, you'd have made a case.
But regarding climate change, GW, or AGW, it's a de minimis mistake.
Btw. in highly charged issues where someone is labeled as this or that,
I'd expect a higher probability of mischief. In such cases, if it mattered,
I check the internet for diversity of opinion. This is often because linked
citations are too often restricted somehow.
