Excellent new presentation on IPCC...
I wouldn't say excellent, although technique-wise it is a pretty good job of being entertainingly deceptive.
If that's all you look at without asking questions about the facts raised I can get how you'd have that opinion about the IPCC. Keep in mind it's not just him. News outlets do the same tricks to keep and increase their viewership. It's not just deniers that do that either... pro-climate talking heads do it too.
So, I'm skipping over the handwaving and hyperbole in the video to just concentrate on the foundational facts.
At 5:29 there's a clip of Tim Ball saying "Maurice Strong (UNEP founding director) wrote the terms of reference which is the definition of climate change and he limited it to deliberately only to the human causes of climate change and that effectively eliminated all the natural causes which is why you see them not looking at things like the sun and a whole bunch of other issues". That's not vague at all. But, it was used as evidence to damn the IPCC. Paraphrasing the rest, the first 600 scientists were constrained by that and the rest were all non-consequential as they could only work with the data from the first team. So, toss out the fruit of the poisonous tree.
As Tim Ball has been built up to be an expert, the thing to ask at this point is... who is Tim Ball? From Wikipedia, he's an energy-funded lobbiest that writes books and speaks out against climate change. He doesn't have a degree in climate science. To quote Tim:
The deception is the hypothesis that human production of CO2 is causing global warming. The hypothesis is referred to as Anthropogenic Global Warming (AGW). The agency that carried out the deception was the UN Intergovernmental Panel on Climate Change (IPCC).
His proof is that the IPCC mandate forbids them from looking at natural causes. Of course, just because his opinion is paid for doesn't mean he's lying. Well, that doesn't require a decree in climate science... so he's not arguing the science, just that the foundation is flawed.
As the quote from earlier Corbett reports said, the only way to know if it's real is to test it.
So, let's see if the IPCC report fails to mention solar, or volcanos, or ....
To the right is a snapshot from the chapter 2 ToC on the Physical Science Basis
What do you know? They're mentioned. | ![1676913515210.png 1676913515210.png](https://diysolarforum.com/data/attachments/135/135847-9a8a686641d2b925cf5a4bfbfe56fc9a.jpg) |
They have to be mentioned (along with a lot of other things like El Nino, zonal modes, the Cryosphere, etc) because changes in climate drivers are important. So, if they do consider that, the tree wasn't actually as poisoned as they want you to believe.
In my opinion, I don't care if it's manmade or not. It's there, the models have successfully predicted the global mean temperature rises which have been observed by satellite and validated by ground stations. The models also consider a lot of factors besides GHGs (like solar irradiance). It's not unreasonable to think if the temperature continues to climb there will be unrest that is far more costly than solving the problem.
What, still reading? Okay... the next factoid is at 16:14 there's a bit about the UNFCCC that its stated objective is "preventing dangerous anthropogenic interference with the climate system". The point they want you to take away is that their mission is to prove man-made GHGs are bad, so of course it is what they will find.... aka they're biased.
This is a very calculated deception of taking something out of context to prove your point. The mission is stated that way as the science had already proved before then that mankind's contribution of GHGs was indeed having an effect, so of course the UN framework convention was established that way, it's why the UN set them up. But, their goal isn't to prove the science or do science (the IPCC doesn't actually take measurements or do science either), it's to figure out how to prevent climate catastrophes without bankrupting the world.
Corbett then goes on to claim that the UN's mandate does not include natural climate change. Which is true, the UN isn't trying to reverse natural climate change, they're trying to reverse anthropogenic changes. That's an example of non-sequitor argument.
But even so, the mandate and the science aren't the same thing and the science can't be studied separately. Scientists don't study CO2 in the atmosphere just from coal, they look at it as a whole.
At 18:39 there's the
startling revelation that the summary is a negotiated political document before the science comes out. Note that it's coming from an opinion piece with only one facts to support it (e.g., timeframes of document publications). It is true that the preliminary summaries come out before the final reports, but that's because it takes a long time to fact-check the
final reports.
Fortunately, facts are easy to come by: The final ARC6 IPCC summary for policymakers was released on 9/9/21 [
ref]. The ARC 6 document, "The Physical Science Basis" was released the same day. The preliminary summary was available in June.
There's also the bit about it being political and they point to quotes that look like politicians are approving the summary and the scientists have to backfill the reports to match the summary. Like all good lies, there is some truth to the first part of that. The IPCC provides summaries for "Policy Makers", these are simpler documents that try to use tiny words for politicians, and the language in them is approved to try and eliminate any possible misunderstanding. The second part is unsubstantiated conjecture.
Hope that's of some help to you.
