Too little, too late? The race to save humanity

Can they really save the planet? Political leaders have returned to Paris and they want a binding deal to curb carbon emissions and come up with enough money to make the switch to renewable energies. But will it be enough to stop the planet from overheating? Is humanity ready to change its ways, or will it be too little, too late? Our special edition of The Debate comes from the COP21 climate change summit in Paris.
