States, towns, and cities are litigating against fossil fuel companies for knowingly accelerating global warming. Kids are litigating against the federal government for endangering their futures. Investors are litigating against corporations for putting the value of their stock in jeopardy. Employees are suing corporations for deceiving them about climate change. Climate protesters are suing to preserve their rights to civil disobedience.

Climate change is not just an environmental issue; it’s a social justice issue, too. It is important to recognize that the people most affected by climate change are often those who have contributed least to its progression. People are recognizing that environmental mismanagement and obstruction of climate action are an infringement on their rights.
