Chevron would like you to know that it believes in climate change. It also believes people cause it by burning carbon-based fuel—the kind Chevron extracts from the ground, refines, and sells. In fact, Chevron believes all this so hard that today its lawyer said so, in a federal court in San Francisco. Intergovernmental Panel on Climate Change? Yup. They’re right. That’s not as up-is-down as it might sound; Chevron representatives have said as much before.
