The climate movement is the collective of nongovernmental organizations engaged in activism related to the issues of climate change. It is a subset of the broader environmental movement, but has evolved as a new movement itself given the scope of the climate change crisis.
The climate movement has rapidly evolved in the past years, starting as one of the many causes of the environmental movement to later become a movement in itself.
Activism related to climate change began in the 1990s, when major environmental organizations became involved in the discussions about climate, mainly in the UNFCCC framework. In the 2000s several climate-specific organizations were founded, such as 350.org, Energy Action Coalition, and the Global Call for Climate Action.
The 2009 United Nations Climate Change Conference in Copenhagen was the first UNFCCC summit in which the climate movement started showing its mobilization power at a large scale. Between 40,000 and 100,000 people attended a march in Copenhagen on December 12 calling for a global agreement on climate. And activism went beyond Copenhagen, with more than 5,400 rallies and demonstrations took place around the world simultaneously.
The climate movement convened its largest single event in September 21, 2014, when it mobilized 400.000 activists in New York during the People’s Climate March (plus several thousands more in other cities), to demand climate action from the global leaders gathered for the 2014 UN Climate Summit.
