Climate Change Conference in Canada

I have recently been spending some time in Canada, in both the Rocky Mountains of British Columbia and the prairies of Alberta. It is hard to travel to foreign countries without thinking about how climate change may effect them over the coming decades.

It is easy to forget that the effects of Actual Global Warming are not just warmer average temperatures. The real threat is extreme weather situations becoming more frequent, more powerful and more likely to cause more damage.

Speaking at the MD of Bighorn’s Living in the Natural Environment speakers series earlier this month, Dave Sauchyn with the Prairie Adaptation Research Collaborative discussed the likely effects that climate change may bring to Alberta. In the prairies, the extreme weather situations could include floods and droughts, tornadoes and lighting storms and in the Rockies, flash floods and mudslides are also a potential danger.

“The big issue is not the averages, but how the extremes will change. The problem is not warming, it is the climate extremes. The big question is not how much warmer will it be in winter, but when are we going to get the next 25-year drought, because it is coming.”

Sauchyn knows the climate is changing, but also knows that is always has been. Some warming is natural. Over the past 150 years, that natural trend can be seen in the temperature records data. However, in the last 30 years, there is difference between the warming that would be expected to occur naturally and the temperatures observed.

“If you look at the entire period going back to 1975, there is a very clear and quite dramatic increase in global temperature. Climate change is a trend, it is a tendency, it is not what is happening today, this winter or the last couple of years. It is what has been happening the last 150 years and what we expect to occur over the next century.”

The discrepancy occurring over the past 30 years has been put through various models and the only explanation for it is the increasing amounts of greenhouse gases in the atmosphere. Whether the nations of the world actually acknowledge and/or take action on greenhouse gas levels or not, societies the world over are going to have to adapt to a changing climate and the extreme events that will accompany it.

“If you think we have had warming already, wait until you see the warming we expect over the next century, depending of course on the amount of greenhouse gases we expect people to produce. It would not be possible for us to be here today if we did not adapt, but we have to adapt even more to sustain our economy and communities with a changed climate.”
