I have a tendency to spend some effort evaluate sources I'm unfamiliar with before I spend time reading their material in detail these days, largely to save time. As such, I glanced around the site and saw they had an article global warming and had a look.

The material looks like it's focused on facts and well-cited, but this rapidly started to feel like a "Merchants of Doubt" kind of product. Feel free to look at the Global Temperature Changes section and make your own assessment - but this feels like politics before (distorted) facts to me, and I'd expect the rest of the site to be similar.
