(EDITED):

That's like saying "Now that we know how to do lung transplants, you can smoke cigarretes all you want."

It seems like not changing the climate is a lot easier than retrofitting the human body for it. Unless, of course, the benefits of changing the climate are so obvious and necessary that it is worth our while to do so.

EDIT: Actually, that's unfair, I didn't even read the article. When I tried to open the Atlantic page it repeatedly locked up my system.

I assume that they meant that we needed to respond to climate change by altering our bodies. I see now an alternative interpretation, that altering the body could somehow prevent climate change.
