The threat of climate change has never been more urgent.

With 14 of the 15 hottest years on record occurring this century and effects ranging from rising seas to extreme weather striking in every time zone, our challenge has never been clearer. With proved and practical solutions such as wind and solar energy becoming more affordable by the day, neither has the way forward.

This is the year we come together as a planet to tackle climate change. This is the year our leaders can take a giant step forward at the United Nations’ Framework Convention on Climate Change’s 21st Conference of the Parties in Paris (COP21) with a global agreement limiting greenhouse gases. This is the year that people everywhere are standing up to ensure they do.

Join others worldwide in demanding a strong agreement at the Paris climate talks that will help get us there. This would include meaningful reduction commitments based on national circumstances, a system of periodic review for these commitments, and a long-term goal of net zero carbon emissions.
