350 Global Warming Protests

Campaigners against global warming organized over 4,300 protests across the globe. The protests were synchronized to happen at the same time and were focused around the number 350.

For some prominent climate scientists, that is the upper limit for heat-trapping carbon dioxide in the atmosphere, measured in parts per million. If the gas concentration exceeds that for long, they warn, the world can expect decades of disrupted climate patterns, rising sea levels, drought and famine. The current concentration is 387 parts per million.

The organizers wanted to show that it was urgent that we need to do something about our emission since we passed the 350 parts per million mark long ago. It is amazing that they were able to organize something this big across the globe.
