France has become the first industrialised nation to ratify the Paris climate agreement.

Nearly 200 countries agreed to limit global warming to “well below” 2°C compared to pre-industrial levels.

More than 170 nations signed the deal in New York in April, however only 17 of them have ratified it so far.

It is believed the deal will not come into force unless at least 55 countries responsible for around 55% of global greenhouse gas emissions ratify it.

French President François Hollande has been reported as saying: “Signing is good, ratifying is better.”

He also urged other European nations to ratify the accord by the end of the year.

Last week the European Commission presented proposals for EU nations to quickly ratify the Paris agreement which have yet to be approved by the European Parliament and Council.
