Forget climate change. The greatest threat to civilization may have manifested itself this week when Kate Upton traveled to the Antarctic to pose for SI's 2013 swimsuit issue.
That'll melt some glaciers REAL fast … girl has no regard for human life!
According to TMZ, which acquired these unreal Kate Upton photos, the model and a camera crew boarded a private 10-day cruise from Argentina to Antarctica.
The photos were shot both on the cruise, with massive icebergs as a backdrop, as well as on the penguin-filled islands off the coast of the frozen continent.
With temperatures as low as minus-35 (not a typo), Kate Upton's bikini photos had to be taken carefully, in chunks of just a few minutes at a time.
The rest of the time, she was bundled up ... fortunately for her, not so much us.
Look for more amazing pictures like these come January-February 2013!
No wonder Kate came in at #6 on our Celebrity of the Year countdown ... although we're starting to reconsider not ranking her even higher than that.
