Sheppard, Mullin, Richter & Hampton is the latest firm to create a practice group around global climate change, which partners say is bound to affect existing clients — and potential new ones.

“I believe that our climate change practice will impact 80 to 90 percent of existing clients in one way or another,” said Randolph Visser, the co-leader of the new group. “Climate change issues cut across virtually every industry that exists today.”
