Paris climate agreement

The COP21 climate change summit in Paris has reached an agreement on climate change.

BBC reports:

A deal to attempt to limit the rise in global temperatures to less than 2C has been agreed at the climate change summit in Paris after two weeks of negotiations.

The deal is the first to commit all countries to cut carbon emissions.

The agreement is partly legally binding and partly voluntary.

The measures in the final draft included:

• To peak greenhouse gas emissions as soon as possible and achieve a balance between sources and sinks of greenhouse gases in the second half of this century

• To keep global temperature increase “well below” 2C (3.6F) and to pursue efforts to limit it to 1.5C

• To review progress every five years

• $100 billion a year in climate finance for developing countries by 2020, with a commitment to further finance in the future.
