Climate change: it is arguably the most urgent and consequential issue humankind has ever faced. How we address it in the next thirty years will determine the kind of world we will live in and will bequeath to our children and to theirs.

In The Future We Choose, Christiana Figueres and Tom Rivett-Carnac--who led negotiations for the United Nations during the historic Paris Agreement of 2015--have written a cautionary but optimistic book about the world's changing climate and the fate of humanity.
The authors outline two possible scenarios for our planet. In one, they describe what life on Earth will be like by 2050 if we fail to meet the Paris climate targets. In the other, they lay out what it will be like to live in a carbon neutral, regenerative world. They argue for confronting the climate crisis head-on, with determination and optimism. The Future We Choose presents our options and tells us what governments, corporations, and each of us can and must do to fend off disaster.

Christiana Figueres is a founder of the Global Optimism group and was head of the UN climate change convention when the Paris agreement was achieved in 2015.

Your new book is called The Future We Choose. But isn’t it too late to stop the climate crisis?
We are definitely running late. We have delayed appallingly for decades. But science tells us we are still in the nick of time.

You say this decade is the most consequential in human history…
This is the decade in which, contrary to everything humanity has experienced before, we have everything in our power. We have the capital, the technology, the policies. And we have the scientific knowledge to understand that we have to half our emissions by 2030.
