Will UN deal to curb climate change work?
Delegates from 190 nations have reached a deal to curb climate change after UN talks in Cancun.
Nations endorsed compromise texts drawn up by the Mexican hosts, despite strong objections from Bolivia.
A fund will be set up to protect poor nations against climate impacts and assist them with low-carbon development.
What do you make of the deal? Will it make a difference? Will the countries who have agreed to the pledge, stick to it?
