The climate crisis isn’t a future we must fight to avoid. It’s an already unfolding reality. It’s the intensification of extreme weather–cyclones, storms and floods, droughts and deadly heat waves. It’s burning forests in Australia, the Amazon, Indonesia, Siberia, Canada and California. It’s melting ice caps, receding glaciers and rising seas. It’s ecosystem devastation and crop failures. It’s the scarcity of resources spreading hunger and thirst. It’s lives and communities destroyed, and millions forced to flee.
