Good for California. I strongly suspect the Supreme Court will throw this out, and even if the oil firms have to pay the cash will disappear into California's corrupt bureaucracy instead of being used for anything useful...
... but people need to know how badly the oil companies betrayed the Earth and the human race in pursuit of profit. They are directly or indirectly responsible for millions, if not billions, of deaths in every country in every continent in the world. They have committed acts of war against every nation on the planet. They have committed not only genocide but ecocide.
And this, if nothing else, gets the message out.
