This development is described completely differently in the different media:

The rebel alliance begins: Governors of New York, California, Washington form a coalition to fight climate change – according to FastCompany.

THE TREASONOUS SECESSION OF CLIMATE CONFEDERACY STATES . Prosecute Governor Brown for treason – according to FrontPageMag.

I find myself in the middle between these extremes. It is just another act of sedition by demonrats.
