#2We're on course for 4+.
1.5 is locked in. Nothing short of a nuclear war will stop 2-3.

#3> Relying on carbon dioxide removal and so-called negative emissions technologies to lower greenhouse gases in the atmosphere over several decades is too risky to contemplate.
Author is saying to not even think about all solutions? Unprompted, on a post ostensibly sharing research findings? Sounds a bit dogmatic and politically motivated. I don’t trust their results.

#5Perhaps we should build an arc to help these species survive the anticipated hot period.

And the ark should go where ?

#7Hate you break it to you but we’re going to overshoot and probably not temporarily

The energy budget needed for CO2 removal makes all our energy consumption done to this point a rounding error.

There are possibilities for removal mechanisms that do not require proportionate input in energy directly. For example, you could perfect growing algae and let the algae extract energy from sunlight on its own. We would just have to ensure good transfer of CO2 from atmosphere to water. Another I have seen is crushing rock -- as silicate is weathering it will naturally extract CO2 and the question is how efficiently you can powder rock.
Another possible solution would be finding a process that will remove CO2 as a byproduct. If you have to put a lot of energy into it, at least get some part of it back.
