The next most expensive city to protect is New York, at $2B. On a per capita basis, the most expensive cities to protect from rising sea levels are Galveston, TX ($21,282/person) and Barnstable, MA ($20,062/person).

According to a study by UC Irvine’s Eric Ringot, and published in the Proceedings of the National Academy of Sciences, Antarctica ice melt has accelerated by 280% in the last 4 decades.
Ice loss in Antarctica has increased from 40 gigatons per year from 1979-90 to 252 gigatons per year from 2009-17. The melt-rate has been accelerating in the most recent decades, up 280% in the second half of the nearly 40 years compared to the first half.
According to the Ice Sheet Mass Balance Inter-Comparison Exercise, Antartica is losing more than 200 Billions tons of ice, annually. This is more than 3X the rate of the last decade and more than 5X the rate of the late 1990s.
