What do you call people who don’t believe in anthropogenic climate change?

“Stupid” is one answer, but I’ve been using “Climate Change Deniers” with some reservations. There is the association with “Holocaust Deniers” and that is bad from an intent point of view, but it does reflect the seriousness of the consequences of inaction.

But I think a good replacement has been found: Simon Singh’s phrase: “Climate Change Numpties“.

It is accurate and gives the right level of ridicule, without being offensive.
