Facebook has suspended the accounts of several environmental organizations less than a week after launching an initiative it said would counter a tide of misinformation over climate science on the platform. Groups such as Greenpeace USA, Climate Hawks Vote and Rainforest Action Network were among those blocked from posting or sending messages on Facebook over the weekend. Activists say hundreds of other individual accounts linked to indigenous, climate and social justice groups were also suspended. The suspended people and groups were all involved in a Facebook event from May last year that targeted KKR & Co, a US investment firm that is backing the Coastal GasLink pipeline, a 670km-long gas development being built in northern British Columbia, Canada. The suspensions, the day before another online action aimed at KKR & Co, has enraged activists who oppose the pipeline for its climate impact and for cutting through the land of the Wet'suwet'en, a First Nations people. "Videos of extreme violence, alt-right views and calls for violence by militias in Kenosha, Wisconsin, are allowed to persist on Facebook," said Delee Nikal, a Wet'suwet'en community member. "Yet we are banned." Many of the accounts have now been restored, but a handful are still blocked. The suspensions came just a few days after the social media giant said it was launching a "climate science information center" to counter ... posts that reject the established science of the climate crisis.
