Like most of us here in London I am hoping that Mr Trump will keep the US in the Paris climate agreement. Climate change is a global problem and we will all need to work together to address it effectively.

Lawmakers from all the developed countries might consider is what will happen if sea levels rise and places such as Bangladesh and the island nations of the Pacific become inundated. Where will their people go? Coping with refugees is a problem now but it could get a lot worse.

This is a global problem. It will need a global solution. American leadership in this is something that many of us would welcome.
