It is a harsh truth of nature that some of the most picturesque views on planet Earth are incredibly dangerous and may only be available for a limited time.

Glaciers are bodies of snow that compress into large ice masses over years. They form as snowfall exceeds snowmelt on high mountains. Cracks form in the ice, which cause the glacier to move. This happens due to precipitation and temperature changes.

The fact that glaciers can move is what makes them very unique, and extremely dangerous. Never walk too close to a glacier due to the hazard of falling ice, and be careful when walking; it is possible to slip into an open crevasse.

In addition, glaciers are incapable of adapting to climate variation. As the temperature increases, glaciers are melting and slowly disappearing. The melting of the giant ice sheets are causing flood dangers as the sea level rises.

But, in some locations, even if the climate remained the same, some glaciers are doomed. According to Homeland Security News Wire, “the most conservative findings of a new research on Bhutan, a region in the bull’s-eye of the monsoonal Himalayas, indicate that even if climate remained steady, almost 10 percent of Bhutan’s glaciers would vanish within the next few decades; what is more, the amount of melt water coming off these glaciers could drop by 30 percent”

So, book your trip today and get a look at these spectacular glaciers while you still can.
