>Have you read the IPCC report? Do you have any kind of physics education and experience in real world thermodynamics at scale?

No and no, but I find it alarming when even trivial questions regarding reliability of methods used to estimate past temperatures are met with ridicule and appeal to authority...

And you are not doing much better. Instead of being curious and asking me what I actually think, or why I think it, you start throwing me research. You also assume that everyone who claims "to think" are coming from some propaganda resource. It is actually the shallow claims from the "convinced" that trigger my skepticism.

It's not about the past temperatures though, is it?

It's about the increasing insulation factor of the atmosphere (unquestionably caused by human fossil fuel extraction) that is trapping more heat.

> you start throwing me research.

That backs that point about insulation.

> Instead of being curious and asking me what I actually think

You either believe in and understand gravity modelling or you don't, either way you fall, clocks advance at different in different frames, etc. A Foucault pendulum swings in a plane independent of the earth rotation regardless of what any human thinks. The starting point for understanding the claims about climate are rooted in physics.

Hence the need to ask people about their foundational knowledge.

> You also assume that everyone who claims "to think" are coming from some propaganda resource.

No, I tend to believe they haven't thought the basic high school level thermodynamics through.

> It is actually the shallow claims from the "convinced"

I worked through via experiments and a few decades in exploration geophysics myself.

Worth a mention that most of the solid data comes not from "the convinced" or eco warrior hippies, it comes from cold war atomic and anti submarine research, mineral and energy exploration, etc.

>It's not about the past temperatures though, is it?

The "crisis" is about "unprecedented rise in temperature", right? So that implies past temperatures.

Not only, also about more extreme weather changes happen regularly and for example in Austria we had now the hottest sommer to be ever recorded.

Extreme weather changes can be natural. The earth has no contract with humans to keep the weather regulated perfectly.

Actually that is the question we are trying to answer when we look at past trends. Is this manmade (if so we can reverse it)? But the sad thing is that we don't have an techniques that can reliably do it. So we take the best we have and declare with unjustifiable certainty, "facts" about past temperatures..
