In his second Inaugural Address, President Barack Obama issued a clarion call for government intervention to combat climate change. But Whole Foods Market CEO and co-founder John Mackey says dire warnings about global warming are overblown.

In an interview with CNBC, Mackay said global warming is “not that big a deal” and may actually be beneficial to human flourishing.

I haven’t been outspoken about global warming. I’ve been smeared quite a bit in the media about it—all of a sudden, I’m a climate change denier. I mean, climate change is obviously occurring. So—it’s gotten a little bit warmer. I guess my position on it is that I don’t think that’s that big a deal. Actually, humanity’s flourished usually when temperatures gradually warmed. And humans gradually adapt to it.

Mackey said he’s concerned government regulations intended to reduce global warming will thwart free-market solutions to address global poverty. “We can probably eliminate poverty on the planet earth in the next 50 years if we will just continue to follow the tenets of free enterprise capitalism to the greatest extent possible,” said Mackey. “So I just don’t want to see that change.”
