We are initiating a WWII-Scale Climate Mobilization to protect humanity and the natural world. Join us!


Humanity faces an existential threat. 

To survive, it’s going to take everything we’ve got.

Join the fight for an emergency climate mobilization to protect humanity.


To protect our world from climate and ecological collapse, we need a new approach:

Our governments and institutions have failed to protect us. It's up to all of us to take matters into our own hands with a new approach that could actually work. 


We can't solve a problem we refuse to look at. Climate change is outpacing official predictions, and accelerating due to feedback loops. Accepted targets and timelines that guided climate action for decades are based on bad data. The scary truth is if we don’t dramatically change course, Earth could become uninhabitable in a matter of decades.


Emergency Speed 

There is no more time for multi-decade solutions. To have a fighting chance, we need to reach zero emissions and drawdown as fast as possible: and in under a decade. This will take massive, sustained reductions in carbon emissions, and concerted collaborative action on a speed and scale we haven’t seen since the home front mobilization during World War II.

Whole society 

A true solution to the climate and ecological emergency must account for all sources of greenhouse gases and overshoot. This means an all-hands-on-deck massive transformation of all sectors of our economy and society. In the process, we can build more resilient, compassionate, and just communities that work for everyone.

WWII-scale climate mobilization is not just ‘a big effort.’ It is not a major project or a key policy initiative like the Apollo Program or even the New Deal.

It is a comprehensive, economy-wide approach that, if done correctly, represents the only realistic way we can overcome the climate emergency.
— Paul Gilding, former executive director of Greenpeace International, author of The Great Disruption

Join the Climate Emergency Movement

The Climate Emergency Movement is a network of people doing everything we can to prevent climate and ecological catastrophe. We ask our institutions and communities to respond to climate change and ecological destruction as an emergency. We demand the only response that makes sense: a massive, just mobilization of our cities and nation to protect humanity and the natural world.


Latest News 

The Climate Mobilization has taken an unflinching look at the latest science and emerged with an honest and realistic plan to save civilization and the natural world.

I hope that we, the American people, heed their call for heroic political action.
— Michael Mann, Climatologist and Geophysicist
