Global warming may make some spots inviting

Predictions about the rate of global warming vary greatly, but even by conservative estimates it’s likely to have a big effect on travel. Many current tourist hotspots will literally be too hot for comfort, while others will lose their natural beauty, be prone to catastrophic storms—or simply be underwater.

According to the Intergovernmental Panel on Climate Change, the planet’s average temperature could increase by as much as 3.5 degrees celsius by 2100, causing sea levels to rise nearly four feet. If the Greenland and Antarctic continental ice sheets then melt—as some predict—sea levels could rise by an additional 30 feet. Potential side effects include increasingly intense storms, catastrophic heat waves and global flooding on a biblical scale.
