Energy-producing states, oil companies, and industry groups filed two challenges to waves of climate lawsuits.

If they are successful, oil companies will pay them billions of dollars, which will be passed on to customers.

"Consumers are not helped by these cases, which seek to wipe products from store shelves and funnel money to left-wing causes," said O.H. Skinner, executive director of the Alliance for Consumers, a consumer advocacy nonprofit.
