The Climate Clock melds art, science, technology, and grassroots organizing to get the world to #ActInTime.

The project is centered on a simple tool: a clock that counts down the critical time window to reach zero emissions (our “Deadline”), while tracking our progress on key solution pathways (“Lifelines”).

By showing us what we need to do by when, the Clock frames our critical mission — a rapid and just transition to a safe climate future — and puts it at the very forefront of our attention.

Since its famous launch in New York in September 2020, Climate Clock teams have sprung up across the world from Chiapas to Kazakhstan, from Korea to Glasgow. Join in.


We are in a Climate Emergency, but there is still time to avert disaster if we take bold, immediate action at the speed and scale necessary – beyond what politicians have deemed politically possible. The next ~7 years is humanity’s best window to enact bold, transformational changes in our global economy to avoid raising global temperature above 1.5ºC, a point of no return that science tells us is likely to make the worst climate impacts inevitable.

The Deadline and Lifeline on the Climate Clock tell us what we need to do, by when. They are arguably the most important numbers in the world. It’s worth understanding why.
