Your 70m of sea level rise is entirely unsupported by the paper you link to, where the worst-case scenario in 2500 is 10m rise. The latest IPCC report in the RCP8.5 scenario (very pessimistic, emissions keep increasing) predicts 62 +/- 20 cm of sea level rise from 1990 to 2100. How on earth will that drive mass displacement of people in the US and Europe? You're saying 75 cm of sea level rise will put entire cities underwater. Which ones, and why are they not already under water? Autumn storms bring waves much taller than 75 cm. Most coastal cities are built to withstand 2 meter waves, probably even more. Besides, they lifted all of Chicago by that much already a hundred years ago. We'll have exactly zero problems fixing this. Look, I'm no climate change skeptic. But the fact that no real life-changing effects are expected for young people today nor our children (in the US/Europe) is the biggest problem in fighting climate change. That, and the fact that literally everything we do today causes emissions.
