Jeb Bush hit back against President Obama’s claim that climate change runs an immediate risk, adding that while it shouldn’t be ignored, it’s still not “the highest priority,” CNN reports.

Said Bush: “For the people to say the science is decided on this is really arrogant, to be honest with you. It’s this intellectual arrogance that now you can’t have a conversation about it, even. The climate is changing. We need to adapt to that reality.”
