Vladimir Putin delivers speech at Paris climate conference

Russian President Vladimir Putin's full speech at the UN climate summit in Paris, France. The highly-anticipated conference, opened by leaders from over 150 countries, aims to yield a new international agreement to reduce greenhouse gases beyond 2020 when the 1997 Kyoto Protocol expires. Such an accord is seen as crucial for keeping the rise in global temperatures within 2 degrees Celsius above pre-industrial times, a goal scientists say should be met to avoid risky changes in the climate.
