the gleaming skyscrapers of China's financial hub Shanghai could be entirely submerged in 600 years

Shanghai ... sank as much as 2.63m between 1921 and 1965

The sea had risen 20mm since 2000 and should keep climbing over the next decade

Rule #1: Always run the numbers.

Lessee, 2.63m in 44 years. 2.63 x 600 / 44 = 36 m.
20 mm in 4 years. 20e-3 x 600 / 4 = 3 m.
Linear projected subsidence relative to sea level over 600 years = 39 m, or about 125 feet.

Man, are those ever some tall skyscrapers!
