New York's former mayor and Vancouver's mayor Gregor Robertson are pushing for climate change policies at the city level.
Thousands of residents are rushing to leave the Thai capital of Bangkok in preparation for more, potentially severe, flooding over the weekend.
The city’s bus and train stations and many roads are jammed by crowds of people attempting to flee. People in several northern districts of the capital – some of which are now 90% submerged by rising water – have been told they should evacuate immediately. More than 360 people have died in Thailand’s worst flooding in decades.
