The $28 Trillion Question

A new report prepared for the insurance industry says that the rise of sea levels could cost port cities $28 trillion by 2050.

"The value of infrastructure exposed in so-called 'port mega-cities,' urban conurbations with more than 10 million people, is just $3 trillion at present.

The rise in potential losses would be a result of expected greater urbanization and increased exposure of this greater population to catastrophic surge events occurring once every 100 years caused by rising sea levels and higher temperatures."
