In Minnesota, climate activist Jessica Reznicek self-reported to the Waseca Federal Correctional Facility Thursday to begin serving an eight-year prison sentence for damaging parts of the Dakota Access pipeline in 2016 and 2017. In 2016, Reznicek and fellow activist Ruby Montoya set fire to five pieces of heavy machinery being used to construct the pipeline. The two then moved up and down the pipeline’s length, destroying valves and delaying construction for weeks.

Reznicek’s imprisonment came the same week the U.N.’s Intergovernmental Panel on Climate Change warned in a major new report that the Earth could face runaway climate catastrophe unless drastic efforts are made to reduce greenhouse gases.
