Bob Tisdale’s Ideological Armour

knmi logoOne of the things that completely baffle me is how climate science deniers can reject evidence.

Of course I’m not referring to not taking something at face value or wanting to verify something before you accept it. What I’m talking about is that they reject evidence even when it’s very obvious that it shows that they are wrong. It also often doesn’t matter how small the mistake it, they will still reject it.

One of these examples is a quote from a recommendations document written by the KNMI IPCC delegation that contained advice for the IPCC on how it can improve its procedures. This included recommendations for improving their reports and how results are communicated. Something that the IPCC asked for and the resulting recommendations from the KNMI aren’t shocking.

However, one passage was a bit confusing as to what they meant by it:

The Ideological Armour Of ‘Climate Sceptics’

Armour by Kamal Aboul-Hosn

Trying to engage ‘climate sceptics’, or so-called sceptics as I prefer to call them, in a fact based discussion is often quite frustrating. Not because you might not convince them to your own position, but because simple basic facts are dismissed. This prevents you from having a factual discussion on how we might want to react towards the changes we are causing in our planet’s climate.

A good example of this was my recent interaction with Bob Tisdale about his interpretation on a passage from a KNMI document:

This Is Why You Can’t Reason With ‘Climate Sceptics’

knmi logoYesterday Bob Tisdale published the blog post titled ‘Open Letter to the Honorable John Kerry U.S. Secretary of State‘ (archived here) on the blog Watts Up With That (WUWT). He also published it on his own website.

My opinion of that letter from Tisdale is that it doesn’t accurately represent the IPCC and their latest release. There are a lot of reasons of why I hold that position and what I wrote for ‘No, Global Warming Hasn’t Stopped‘ gives a good introduction about his mistakes about climate models. I can also recommend the article ‘The new IPCC climate change report makes deniers overheat‘ by Michael Mann for a better understanding of how the latest IPCC report often is misrepresented.

When I started on my open letter to Tisdale I knew we would never reach any sort of agreement on his points about climate research or the IPCC. That’s why I focussed on the following in his letter:

An Open Letter To Bob Tisdale

knmi logoDear Mr. Tisdale,

I noticed your recent contribution to the blog Watts Up With That titled ‘Open Letter to the Honorable John Kerry U.S. Secretary of State‘ (archived here). In it you criticize the IPCC and the scientific findings they presented with their latest report.

My opinion is that you’re not accurately representing the IPCC and their latest release. The reasons for that are numerous, and if you want to get a better understanding of what I mean by that I can recommend reading ‘No, Global Warming Hasn’t Stopped‘.

But we will probably never reach agreement on that point so I’m not going to focus on it. However, what I am going to focus on is the following that you said in your letter:
