From Russell Seitz in the Wall Street Journal (a sub. link):

The inconvenient truth — that ill-placed “carbon offset” reforestation schemes can backfire could give rise to a legal climate of fear. Will environmental lawyers chasing tree surgeons’ ambulances become the next big thing in torts? The climate modeling game affords few certainties, but it seems likely that carbon-offset lawsuits will sprout like kudzu from this fertile new research field. As it grows, will the green state attorney generals who took the EPA to the Supreme Court end up inviting the former next president back for an encore?
