The Supreme Court is being asked to block climate change lawsuits filed against oil companies by California and other blue states.

Oil and gas companies are asking the Supreme Court to block dozens of high-powered lawsuits from California to Massachusetts seeking to hold the industry liable for billions of dollars in costs related to climate change.

They are urging the justices to intervene now and rule that climate change is a global phenomenon and a matter for federal law, not one suited to state-by-state claims.
