1. Even gravity isn't settled: https://youtu.be/8RCG_4JG6Hg?t... (really, you should watch - if it pans out this as big as relativity - extraordinary claim require extraordinary proof of course)
2. OK, but it is still annoying. And to be honest, I really think the politicians are driving most of the discord on this.
3. Micheal Mann (the actual scientist writing many of those papers, and the actual gatekeeper of what gets published) was the one testifying to congress.
4. I actually don't visit any "denialist" web sites other than Judith Carrie's site on occasion when someone else points things out to me. I read the source data, which you obviously haven't. I can't believe you linked to the IPCC reports! Those are the specific ones that have been falsified!
From the 1992 IPCC report titled "Climate Change: The IPCC 1990 and 1992 Assessments", in the "Policymaker Summary of Working Group I", page 74 there are charts showing predicted temperature rises, and discusses several options for dealing with CO2. The temperature anomaly in 2018 is given as about 1.7 in "business as usual", and 1.5 for their different scenarios. The actual temperature anomaly for 2018 was about 1.4, less than all those mitigation scenarios that did not happen.
On page 81, sea level rise predictions were made. 2018 was supposed to have a sea level of 15 cm compared to 1990. The actual value was 8 cm.
I could go on. Obviously, you have not read the reports. (I was trying to find the slide where they have the error bars on the prediction results, that is the one I was referring to, but I don't want to spend the time on it. We are now well outside the error bars.)
I don't argue against good science. I do argue against bad science. I am willing to accept the anthropomorphic catastrophic global warming hypothesis once the verifiable facts outweigh the certainty that I am being lied to. When I catch someone lying to me, I have to severely discount what they say. Because if they could have proven it without lies, they probably would have.
