Climate change is our reality. Here's how we're taking action | Al Gore, Gloria Kasang Bulus, Nana Firman, Ximena Loría and Tim Guinee

With the Climate Reality Project, Al Gore is helping mold future leaders to build the movement for climate survival and social justice from the ground up. He introduces us to four of the Project's graduates, each of whom confronts climate change on their own terms: Ximena Loría, founder of Misión 2 Grados, an NGO influencing public policy in Central America; Nana Firman, "daughter of the rainforest" and advocate for climate justice among Indigenous peoples; Gloria Kasang Bulus, a Nigerian activist for women and education; and Tim Guinee, a first responder and climate change fighter in upstate New York. Together, they're gathering local actors into a global, grassroots movement that aims to turn the climate fight around.
