CO2 levels are climbing past 400 parts per million. Can you help take our movement to the next level?

Last week the world's most important CO2 observatory recorded a daily average of above 400 PPM for the first time in history. The challenges are growing, and so our movement must keep growing as well.

Can you chip in to help us plan for the next 6 months of organizing?

We'll put your donation to good use. Our crew is lean and frugal, and we make every dollar count. Many thanks!

With your support, we'll be able to:

Resource mass actions targeting the fossil fuel industry on all fronts

Bring on additional organizers to support divestment campaigns across the world.

Spark a wave of global climate activism as part of Global Power Shift

And lots more to support the growing climate movement.
