BBC: Representatives of 195 nations are in Peru for a two-week United Nations (UN) conference to continue efforts to reach a new global climate agreement. The meeting follows the warmest January through October period on record. The UN is continuing its work to finalize a climate plan in time for a meeting in Paris at the end of 2015. At the Peru conference, negotiators hope to build on momentum from a recent bilateral agreement between China and the US and from promises of more than $9 billion to the Green Climate Fund. One of the tasks is getting all countries to agree to the scope and ways in which they can set targets for cutting carbon emissions. Developing nations want to include finance and adaption policies because proposing only direct cuts to emissions would hurt their efforts to grow their economies.
