In a recent interview, former Vice President Al Gore challenged Americans to stand up against climate change deniers and "win the conversation" the way people stood up to racist comments during the civil rights movement.

It may seem difficult to stand up against people who insist that climate change is not real. But while explaining the science of climate change is no easy task, pointing out the reality of climate change is necessary in order to really stop this dangerous pattern once and for all.

During the civil rights movement, people stood up and spoke out against racism in America. It took courage and conviction, but in the end their voices were heard. We need to speak out as one about the reality of climate change, and we will be heard as well.

Please pledge to speak out when you hear someone denying climate change. We need to "win the conversation" in order to preserve our planet for future generations.
