#12It’s quite clear that in 2019 it is not possible to get all powerful entities in the world to work together on an issue like climate change. We should focus on band-aid solutions like reflectors in space above the poles that prevent sun from hitting the earth at all. We are past the “if only everyone bought electric cars” phase of solutions and need special projects that assume the amount of CO2 emitted stays the sam…
There's no stationary orbit over the poles
the latest climate-engineering proposals for sunshades involve placing a cloud of reflective or diffracting solar sails at L1, not in close earth orbit over any specific region.

#13potentially very dumb question but could you build hydro power solutions(from the ice melt/run off) that you then get clean power from / help cool ice...? So out of my depth here but genuinely curious. Also appreciate building a hydro power plant on a very unstable platform (ice) is problematic just curious of other solutions to generate hydro power...
No, the scale of energy potentially captured would not come close to the amount of energy needed to cool tons of water below freezing.

I have no idea if that’s possible, what I mean is we should stop trying to get the US and China to agree on anything let alone climate change so we need grand silver bullet solutions.
China does accept the reality of climate change and is enacting policies against it. It might not be nearly enough but it's not fair to lump them with the USA on this one.

#15To be clear, the 2m increase is the analyzed 95th percentile (very high end) of the estimates of this meta-study, when you take both glacial melt and glacial expansion. The median values for low and high estimates are 69cm and 110cm.
Not that this isn't still terrifying, worth of action, worthy of international collaboration, and so on. Just let's be accurate about our titles.

#16If you are interested in seeing a map of sea level rises, the NOAA publishes a website with one. At 7 ft there are significant coastal differences.

The first problem is what you do with the billion displaced people. That’s not a tech problem, so much as an ethical / pragmatic problem.

We probably don't want all powerful entities in the world working together on anything anyway. Nothing good can come of that. A diverse range of localized solutions reacting to local experiences and problems is better than top-down central-planned solutions.

I don't see the word "orbit" used at all, except by you.
Sounds like you'd imagine a permanent eclipsing body is something that would employ an orbital insertion into earth orbit, which is your own assumption.
