We have at most ten years - not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions... We are near a tipping point, a point of no return, beyond which the built in momentum and feedbacks will carry us to levels of climate change with staggering consequences for humanity and all of the residents of this planet.
James HansenPlanet Earth, creation, the world in which civilization developed, the world with climate patterns that we know and stable shorelines, is in imminent peril.
James HansenAs species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
James HansenThe climate system is being pushed hard enough that change will become obvious to the man in the street in the next decade.
James Hansen...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.
