194 countries attending the 17th Conference of the Parities to the UN Framework Convention on Climate Change (COP17) in South Africa have signed the deal that will for the first time see all countries work towards a legal agreement on the climate by 2015. The agreement will come into force from 2020. The next commitment period of the Kyoto Protocol has also survived, an issue which activists were particularly concerned about.  The Green Climate Fund has also been launched, with several developed countries - including the UK and Norway - already committing money. The Fund will be crucial to developing countries, which need assistance in developing adaptation strategies as the climate changes.
