Is Global Warming Affecting Your Snowmobiling Time?
Your opportunities for snowmobiling may be limited in the future. The Intergovernmental Panel on Climate Change says evidence for global warming is “unequivocal.” While this year the United States and Canada saw an early winter and stupendous riding, experts say climate change is already beginning to have an impact on recreation that involves snow.
Climate Change Facts
Sometimes it’s hard to tell truth from hype, but NASA provides reliable data on global warming. The Earth’s climate has always fluctuated. In the last 650,000 years glaciers have monopolized most of the planet’s surface seven times, with the last ice age ending just 7,000 years ago. However, in the past hundred years, man has disrupted natural cycles.
NASA says there’s a greater than 95 percent probability current warming is due to human activity. Experts measured carbon dioxide (CO2) in the atmosphere and deep in ice cores to chart levels at different times during history. Since the Industrial Revolution, CO2 levels have skyrocketed, more than doubling their highest level at any time in the past.
Earth’s surface has gone up two degrees Fahrenheit in the last century, with most of the warming occurring in the last 35 years. The oceans are warming and the ice sheets continue to decrease in mass.
Impact on Snowmobiling
ScienceDirect created models to simulate snow at 247 recreational areas across the United States and applied data from five climate forecasts and two emissions predictions. They extended current weather pattern trends into the year 2090 and calculated the impact on both the snow season and the recreation industry.
