Nations ‘must ramp up emissions fight’

Countries must massively ramp up their action to cut emissions to prevent global temperatures rising beyond dangerous thresholds, a UN report warns.

It says cuts to greenhouse gases must triple compared to plans over the next 12 years to keep temperature rises to 2C above pre-industrial levels.

And to meet the more stringent aim to curb temperature rises to 1.5C to avoid more extreme damage, levels of ambition on cutting emissions must increase five-fold, the UN Environment study said.
