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:

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:
On YouTube I found a couple of videos about the new IPCC report that I found interesting. Especially since in 3 of the 4 videos we have the scientists that worked on the report explain what is in it.
In the first video we have several scientists explaining the context and meaning of the slow down in surface temperature increases. It’s a good and short rundown on what is happening, why, and what this all means.
Ever since I’ve been aware of Piers Corbyn I’ve found him extremely confusing. Simply because what he says is so at odds with what we know in science, and because he’s very secretive about how arrives at his conclusions.
What I’m referring to are the weather predictions he makes via his company WeatherAction. What his company does is make long-term weather forecasts based on solar activity, the earth’s magnetic field, and the moon’s orbit. He calls it the Solar-Lunar-Action-Technique, or SLAT for short. He claims he gets a high rate of success with this technique and can predict the weather up to a year in advance; but I’m not convinced.
The problem is that what he uses for his predictions, like the sun, has at best a minor effect on weather and our climate. This is well known in the scientific community, yet he claims it has a big effect. But it’s also Corbyn that claims this high accuracy, there’s actually very little out there that hints at there being any skill to his predictions.

Although the article is quite hard to address as he barely mentions any sources for what he’s basing his claims and arguments on. And he does make a lot of claims about climatology and the IPCC.
To show I’m not taking anything out of context his entire blog post is quoted by me, with my responses to the point he’s making below the quote. I’ve kept my responses as short as possible, which means I’ll be referring you to a lot of other sites/pages for further information.
But before I begin I’d like to point out that any bolded or emphasized text in the quotes is by Dr Roy Spencer. I copied the text as is from his blog so that I don’t distort what he’s saying. That being said lets begin:
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.
Ever since I’ve been aware of Piers Corbyn I’ve found him extremely confusing. Simply because what he says is so at odds with what we know in science, and because he’s very secretive about how arrives at his conclusions.
This time I noticed a blog post called “
