Warning as hurricanes hit US

Harvey and Irma should serve as wake-up call on global warming

It is sobering to learn that Florida, known among Chinese as a popular tourist destination and a place where heads of state of the two countries held their first meeting in April, is being devastated by the Hurricane Irma.

Residents were expected to be allowed to return to parts of the Florida Keys on Tuesday to survey damage from Irma, which devastated the state with high winds and storm surges that ruined homes and left millions without power.
