Congratulations for falling into the biggest,and most obvious trap when it comes to forecasting climate change: you've taken your short timescale reference and weather patterns in a small area as symbolic of how the entire planet's climate is changing over a long time.
Let's get one thing straight: Weather is not climate.
In the 60s Loch Lomond froze over completely for two winters; in 1994 Scotland had an incredible amount of snow; in 2006 the whole country had a scorching summer and lost most of its water. Then it rained for 18 months solid....
The point is these events cannot be taken as symbolic of the climate going one way or another; the frame of reference is far too short to extrapolate out. I really wish scientists would be more honest and just say "I dont know what's happening".
One last thought which relates to animals and weather/climate: has there ever been a single documented case of something in nature staying constant? I dont believe so. Animal populations ebb and flow due to all sorts of reasons (take any British bird species for example) and so does the climate. We should try not to panic so much and instead aim to clean up our act as a race because our current resources will run out rather than something that is impossible to prove.
