Big Oil asks Supreme Court to kill climate lawsuits before trial

The US oil industry is asking the Supreme Court to block a group of climate lawsuits from proceeding to trial, arguing that federal law should preempt state-level claims of climate deception. The lawsuits, filed by several states, accuse oil companies of deceiving the public about the risks of climate change. The oil companies, including ExxonMobil, BP, Chevron, and ConocoPhillips, argue that federal law preempts state laws and regulations related to climate change, and therefore the lawsuits should be dismissed. The Supreme Court will now consider whether to take up the case.
