Sometimes we have to step back and look at the big picture. We have to remember that not everyone has heard or believed the one about global warming stopping in 1998. Denialists centre around nitpicking and ideas that global warming is a “house of cards”, so we respond the same way: countering all the “mistakes” they claim to have found.

In reality, climate change is an incredibly robust phenomenon that we’ve known about for decades – and the basic physics behind it, for over a century. It’s not some new, shaky discovery. It’s not going to be overturned because scientists at CRU do not always say nice things about their critics.

So I was very pleased when I opened up YouTube today to see that Peter Sinclair’s latest video was all about this big picture. If I had to choose just one of his videos to share with everyone I knew, this would certainly be it. This is the kind of message we need to get out there; this is the kind of angle we need to take.
