Final Focus; further research needed

As I wrote my blog analysis, I decided that in my last two articles and field experience, I would bring my focus back to the effects of global warming on ski resorts. I think that the research I've done regarding efforts of ski areas and companies to slow global warming builds up to a finale of what is happening now. If I can, I will find an article on a ski area which is really struggling, and possibly one that is in New England. I am once again looking for statistics from this year and previous years, and predictions for next year's weather. I hope to gain a lot from my field experience, and I hope that whoever I interview will have a lot to say about my topic, and I want to get input on this issue from several people.
My change of focus is coming at the most climactic point in the ski season, when we (hopefully) get the most snow. I think that I'll integrate what I've learned about ski companies into my field experience, and bring up their efforts in my interview(s). This is an exciting point in my research, and I am looking forward to learning more.

Cold winter doesn't buck global warming trend RESPONSE

This is the most interesting article I have found so far. I had no idea that Switzerland has such a strange climate, that is different from anywhere else in the world. I also found it interesting that Wanner, though he is an expert on the subject, still doesn't fully understand this "sarcastic" pattern. This makes me wonder how a climate shift would effect this particular system. Would the fluctuations be farther apart (more than six to fifteen years)? Would we have an abundance of cold or warm weather? Would we have cold weather with little snowfall, or vice versa, or neither? This was a thought provoking interview.
Another interesting point was that there are two "seesaw" patterns; one that applies to the temperature, and one that applies to the amount of precipitation. The way I understand it, We have an abnormally stormy period when a large amount of precipitation and cold weather line up, which is every 1 out of every 10 periods of six to fifteen years. This could be what Switzerland is experiencing right now. I wish the interviewer had asked Wanner if there really was a pattern in this cycle, or if it was random. Nevertheless, I am excited for climatologists to figure out this system, so that we would be able to accurately predict when the next big winter(s) with above average snowfall and below average temperatures would occur.

Cold winter doesn't buck global warming trend

This is an interview with Swiss climatologist Heinz Wanner, regarding the abnormally snowy year in Switzerland. When questioned about global warming and Switzerland, Wanner said that Switzerland's climate is very "sarcastic", and that it is a "seesaw", and the amount of snowfall is dictated by winds, which seem to form a pattern over time. "Looking back a few hundred years we can see we had this in the past. It was positive before 1950, then negative between the '50s and early '70s. It was clearly positive again in the late '70s to late '90s, and then negative again." This system is unlike anywhere else in the world, Wanner says. To understand it, we would have to "diagnose whether the influences are anthropogenic or natural, we need to look at data over a very long time and a very large area." Wanner admits that even though he is an expert on the subject, he still doesn't know much about the process in detail. The point of this article is that people should not dismiss global warming, and they need to understand that Switzerland relies on a completely different system from the rest of the world, and the fact that this year is particularly snowy is purely coincidental. Wanner also says that people should not "go ahead and book their ski trip for next year" just because of the conditions now; everything is subject to change every six to fifteen years.
