Reddit reviews Global Physical Climatology

I'll recommend Hartmann's Climate book.

If you ever wanted to learn about the climate system and all sorts of fun things this is where I'd start!

Dennis Hartmann's textbook is an excellent introduction to Climate Science, with a few concluding chapters on natural and anthropogenic climate change.

The fact that CO2 concentrations are increasing in the atmosphere is literally the definitive consequence of an imbalance in global carbon dioxide fluxes. I'm getting this idea from the observations and my knowledge of the global carbon cycle and basics physics / chemistry. Since CO2 is a greenhouse gas, this also leads to a measurable energy balance.

Actually, the fact that CO2 emissions are increasing global temperatures has a overwhelming amount of support from climate models and direct observations of the greenhouse effect.

You're making all these wild claims about things we don't know or things you have to account for which I assure you climate scientists are aware of and account for. All of the questions you've asked were covered in my introductory Climate Science course. The literature on this stuff is very well established.

Also, why did you just make up that humans contributed 20 ppm for the current 400 ppm? It is abundantly clear that almost all of the CO2 increase from 310 ppm to 410 ppm between 1960 and 2017 is due to us. We know this from the oxygen isotopes of the CO2 and we know it from doing global carbon budgets. All of you claims are totally baseless and easily debunked by reading an introductory Climate Science textbook, so I will leave it at that.
