It has taken many years to get to this point and two weeks of often round-the-clock hard bargaining at the COP21 summit in Paris.

At last, delegates have now come up with a plan on how to curb climate change, aiming to cut emissions and phase out fossil fuels.

The goal is to limit the rise in global temperatures to 1.5 degrees Celsius above pre-industrial levels.

The deal, which French Foreign Minister Laurent Fabius said is "legally binding", also includes a five-year review of how countries are doing with their climate plans.

Some experts, however, are not convinced the agreement goes far enough.

So can it hold? Is it fair? And crucially, will it usher in changes radical enough to save the planet from catastrophic temperature rise?
