I work with a few climate scientists so my opinions aren’t my own. I referenced 2 researchers above, what is wrong with their opinions?

[4] isn’t climate denial, it was an attempt to get some criticism of an interesting heterodox theory, and I found it! [5] CCS is being used at large scale on many projects. Maybe we have different definitions of “at scale” and “successful”

I don’t need to prove it can be done: we already produce these with emissions and we already have CCS to avoid these emissions, there is nothing technological stopping this except economics.

The consensus is that climate change is real and I agree wholeheartedly. What I disagree with is exaggerations of the negative outcomes and rejections of technological solutions based on politics rather than science. In this aspect you will find many conflicting opinions.

Also please answer my question about 2C. Asking this is what led me to realising how much of climate policy is based on convenient politics and not science.

You keep saying climate policy is based on politics, but you are not providing any evidence of that. Please provide evidence of your assertion this is political. You argue that "there is nothing technological stopping this except economics"; that means it isn't feasible unless proven the economics will improve. A proof of concept does not guarantee scale.

My evidence is the lack of a basis for 2C and lack of a cogent plan to limit warming to 2C. I tried to find the basis and instead just found lots of IPCC discussions with no scientific basis.

That’s why I asked: you can find articles saying that a degree of difference is very important, but not the basis for why 2C is used.

If you are arguing that fossil fuels must be shut down immediately, you must have an understanding of why 2C is used, and the difference in harm between 2C and whatever we end up with if we keep emitting. If you are not aware of this science in these cases then you are basing your beliefs on politics.
