Will The Rockies And Northern Canada Be Snow-Free By The End Of The Century?
September 30, 2013

What would the Rocky Mountains and Canada's North look like without any snow? According to this visualization, based on data from last week's UN Intergovernmental Panel on Climate Change report, it's possible that a snow-free northern Canada could be a reality by 2100. 

The IPCC report presented four different scenarios for future climate change. The scenario in the video, which was created by the NASA Centre for Climate Simulation, is based on an average of those four possible outcomes, with areas of red representing severe rises in temperature and blue patches showing where rainfall is expected to rise the most, compared to a baseline of data from 1971–2000.

According to the video's narration, "the largest temperature increases are seen in the northern hemisphere. Across North America, areas that typically have snow, such as the Rocky Mountains and northern Canada, will see the earliest and largest temperature rise."

Without white snow cover, the projections say, those parts of the world would also absorb more energy from the sun, causing them to heat up even further.

While the prediction of a snowless north is alarming, some climate scientists have cautioned that the report's predictions are speculative, and should not be viewed as certain.

"It is a complete fantasy to think that you can compile an infallible or approximately infallible report, that is just not how science works," Professor Myles Allen, one author of the IPCC report, told The Telegraph. "It is not a bible, it is a scientific review, an assessment of the literature."
