“Engineers might be able to protect Arctic ice by coating it with tiny glass bubbles. Should they?”

No.

You seem to think the answer is obvious? Why?

If the entire polar ice caps melt sea levels will rise approximately 230 feet. That's the end of every coastal city in the world.

Given how all data trends point to how we are pretty much going to fail at stopping global warming, the glass bubbles are 100% worth considering EVEN when you consider the potential negative side effects.

Here's a better solution than glass bubbles or whatever geo-engineering stunt people come up with: how about we adjust our culture and attitude to value the biosphere instead of feeding it into a meatgrinder; to encourage companies to make things that last instead of making things that break and need to be thrown away; to look at our energy use and just stop using so much of it.

How about that?

Wikipedia

> In the next 2,000 years the sea level is predicted to rise > by 2–3 m (6–10 ft) if the temperature rise peaks at 1.5 °C (2.7 °F), > by 2–6 m (6–19 ft) if it peaks at 2 °C (3.6 °F) and > by 19–22 m (62–72 ft) if it peaks at 5 °C (9.0 °F)

Additionally

> If temperature rise stops at 2 °C (3.6 °F) or at 5 °C (9.0 °F), the sea level would still continue to rise for about 10,000 years. In the first case it will reach 8–13 m (26–42 ft) above pre-industrial level, and in the second 28–37 m (92–12 ft).

It is over 2000 years though. By 2100 the absolute worst case scenarios have sea level rise at about 2m

(note: I rounded down halves of ft to make it more readable, but the metres are unchanged)

Do you have any citations for that specific figure that lay out a timeline?

I want all coastal cities to flood.
