Last week a co-worker pointed me towards the Twitter account of Dutch research journalist Marcel Crok. His concern was mostly with some recent factually incorrect tweets on this account. But as I started to browse through his time-line another tweet grabbed my attention. The tweet has since been running through my mind. Not because it is a particularly good tweet, or that it makes a good point. It’s not even a funny tweet either. In fact, I find this tweet so fascinating because there is a lot wrong with it.
One 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.
Yesterday 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:
Dear 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‘.
Yesterday I published a long response to the comments I received from Marcel Crok. In it I expanded on what I said and referenced, and dealt with his points towards me.
Not long after the release of my blog post Crok responded to me with a short comment. It won’t take me long to give my final take on this exchange.
After I published the response I received from the KNMI I did a few pokes on Twitter towards Anthony Watts and Marcel Crok to see if they were willing to respond to it.
I also left a comment about it on Crok’s website where I quote what the KNMI said (I couldn’t do this on Watts’ website as the comment section was already closed).
So far I haven’t received a response from Watts, but Marcel Crok was kind enough to engage me in his comment section. I’ll be going through his responses to me in this post and my take on them.
Before I do that though I have to compliment Crok for being respectful and civil towards me, despite me being quite critical towards him. It’s something that’s often severely lacking from any public exchanges that take place. Being able to engage someone while being quite critical and at the same time having a civil exchange was a breath of fresh air. It’s just sad that this is the exception.
Now lets start with his first response towards me, which I found a bit strange:
To be short: yes, the KNMI had some criticism towards the IPCC and how they operate. However, it wasn’t the type of criticism the so-called sceptics thought.
What the KNMI did was provide recommendations to the IPCC to 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, the so-called sceptics seemed to think differently. Marcel Crok, one of the more known Dutch so-called sceptics, wrote an article about it and Anthony Watts published the following snippet from it on WUWT (emphasis added by Crok):
