Yesterday was the climate change global day of action. People all over the world had been preparing and recruiting for the occasion for weeks.

According to the grassroots climate campaign website 350.org, there were over 5,200 events all told, in 181 countries. That makes it easily the most widespread environmental action day to date. The 350.org website contains a slideshow of some of the more photographable activities from around the world.

The whole bit about "three hundred and fifty parts per million" (350ppm) may have confused onlookers a bit, but these sort of events are about galvanising the movement itself more than recruiting many more people to it. We have a hard struggle ahead of us between now and Copenhagen, so the timing (if not the messaging) is spot-on.
