2009: International Day of Climate Action (24 October)
A day to remember...
The 24th of October, 2009 marked the first 350 International Day of Climate Action. It turned out to be what CNN called, "the most widespread day of political action in our planet's history."
That's on any issue, let alone climate change and 350 ppm. It was a tremendously powerful day and has proven a critical moment in building the global grassroots movement we need to overcome the climate crisis.
Check out the video and slideshow below, and take some time to explore the many beautiful photos from the day...
