The Supreme Court must decide this issue on climate lawsuits someday. Why not do it now?

“​Don’t put off until tomorrow what you can do today.” 

This aphorism — attributed (perhaps spuriously) to Benjamin Franklin, Thomas Jefferson and others — provides wise counsel for the U.S. Supreme Court. That's especially true as it decides whether to grant a pending petition for certiorari asking it to decide today whether federal law preempts or otherwise precludes state common law public nuisance and similar claims seeking redress for injuries allegedly contributing to climate change effects.
