FTA: From The Article: A systematic refutation of these bad arguments requires a book, and there are many good resources out there, but I just want to focus on one argument in this article – the notion that the climate is always changing. This, of course, is true. It’s simply not a refutation in any way of the scientific position of anthropogenic global warming.

This is one of the many positions of the deniers. First they will argue that the climate is not changing. When the evidence for that is too irrefutable, then they say that it is always changing. This is also where the unmitigated hubris comes in – they bring up the point that there are natural trends in climate change as if this is news to anyone. Oh really, you don’t say? The climate naturally changes? I wonder if the world’s climate scientists, who have dedicated their careers to thinking deeply and carefully about things like the climate, have ever encountered that notion before. You should tell them.
