Canadian seasons affected by climate change

Environment Canada alerted on Friday that Canada will be brought the coldest winter in virtually 15 years by the weather phenomenon La Nina. The majority of the country will experience a “temperature anomaly” of below-normal temperatures during the months of December, January and February is exposed by Environment Canada’s temperature forecast. Above-normal precipitation will also be perceived by much of Nova Scotia, Saskatchewan, Alberta and parts of British Columbia and southern Ontario.

La Nina, meaning the little girl, is being the emergence of cooler-than-normal waters in the eastern and central Pacific Ocean. Environment Canada’s website says: “La Nina is thought to occur due to increases in the strength of the normal patterns of trade wind circulation. For reasons not yet fully understood, periodically these trade winds are strengthened, increasing the amount of cooler water.”

Wetter-than-normal conditions in the northern hemisphere and changes to the jet stream over North America are effected by these cooler waters. Environment Canada says: “The shifted jet stream contributes to large departures from the normal location and strength of storm paths. The overall changes in the atmosphere result in temperature and precipitation anomalies over North America which can persist for several months”.

Drought and floods were made around the world by La Nina in the period of time. More hurricanes in the Atlantic are also affected. Parts of Western Canada have already experienced the effects of the weather phenomenon. Nearly 80 centimetres of snow on Whistler, B.C. over 48 hours was dumped by a ferocious storm earlier this month. Management was impelled at the famous Whistler Blackcomb ski hill to open one week in advance of schedule by the massive snowfall.

While it is true that some countries or parts of the world would be suffering more from global warming, it is the whole world and whole humanity that would come under effect. Now that scientists are already pointing out to the adverse effects of climate change on the seasons also, it remains to be seen, how these countries would tackle with the problem–the developed countries are encouraged to do more on their part, so that developing countries and under-developed countries could follow the suit.
