On September 21, the biggest climate change demonstration ever recorded took place in 166 countries, with 2,208 individual events in different cities. The main rally took place in New York, United States, with more than 400,000 people gathering in the streets to make their voice heard by policymakers gathering for the UN climate summit taking place today.
But tens of thousands marched in other cities too, speaking with one voice across the five continents. Here we present photos from the demonstrations that took place in three of our regions, and in London, where SciDev.Net’s global edition has its headquarters.
