On Saturday, April 4, 2015, over 25,000 citizens marched in Quebec City calling on Canadian Premiers and the Federal Government to Act on Climate. I was contracted by Greenpeace to cover this huge moment. Those images have been shared and used widely on the net the last few days, including over 15,000 times here on ThinkProgress. I believe that this march is a sign that the climate movement has hit a tipping point.
