Row over legal nature of Paris climate deal

France's foreign minister says US secretary of state John Kerry must be 'confused' after he questioned whether any COP21 accord would be legally binding

Any global climate change deal reached in Paris next month will be legally binding and have a concrete impact, France's foreign minister said on Thursday, reacting to US comments that questioned the status of the accord.

The US secretary of state, John Kerry, was quoted as telling Wednesday's Financial Times that December's agreement was "definitively not going to be a treaty".
