Solutions to the world’s converging environmental crises may not always align, the Biden Administration’s climate czar said last week.

“There are a lot of hard conversations around the clean energy transition that we haven’t figured out yet, that there’s certainly not a global consensus on, let alone an American consensus on,” White House National Climate Advisor Ali Zaidi said in a fireside chat March 13 at Stanford University.

“The one example of that is conflicts with species, not with humans but with biodiversity. If anything the biodiversity crisis is blinking brighter, faster than aspects of the climate crisis. I don’t want to pit one crisis against the other, but we are seeing precipitous decline of species diversity, and when we have conversations about things like transmission—and we have live projects now that are facing this issue—it’s a real big challenge.”
