Jon Huntsman appears to be softening on his position regarding the man-made climate crisis:
"The scientific community owes us more in terms of a better description of explanation about what might lie beneath all of this. But there’s not information right now to formulate policies in terms of addressing it over all, primarily because it’s a global issue."
It's not a total walk-back, but you can tell he's trying to leave some doubt for the far-right wackaloons, who refuse to believe what nearly every scientist regards as fact, simply because liberals have traditionally believed it.
