How can we defuse extremism, spur positive action, and win allies in the fight against climate change? Ask United Nations Champion of the Earth and World Evangelical Alliance climate ambassador Katharine Hayhoe.

As a Canadian living in Texas, climate scientist Katharine Hayhoe has learned how to successfully navigate the political minefield of the climate change debate. She negotiates skepticism of the science, indifference to the harmful impacts, and resistance to the actions needed to avoid those risks. Rejecting scare tactics or guilt trips, Katharine engages with the cautious and the doubtful by finding shared values—and she says you can, too.

In The Answer to Climate Change, Hayhoe shares her journey in talking about climate. The result is an engaging look at science, faith, and human psychology, without the political theater. Katharine argues that alarmism around climate turns off the undecided and promotes hopelessness among those who want to bring about change.

So, how do we start a meaningful and productive conversation with our families, friends and colleagues about climate change? With warmth and humanity, Katharine shows how all of us can, and why all of us must, play a role in saving our future.
