Did you keep records of your coat okie?
I provided records of ice out on lakes. Did you bother to look at it?
The Audubon Society keeps records of birds

which shows they have moved farther north over time
Now about your sound and reliable data gathering methods okie....
Pretty interesting, Parados, but I think your evidence gets at least a "D", if not an "F". First of all, I used to be an amateur birdwatcher, and I kept bird lists as a hobby when young. And although I am not a member of some birdwatching society as Audubon now, but I have seen them several times walking around on local trails in their khaki shorts and binoculars counting birds. They are sort of a humorous lot of people, to be perfectly honest.
Now maybe you claim such casual or amateur sightings of birds can be scientifically sound enough to make some grand pronouncements of global warming, but I do not. Having done quite a bit of this sort of thing, and frankly I can still identify most common species, I would caution you about how accurate the identifications of species actually are by such people, and I would also put a big asterisk by the numbers of birds observed. Such is far from representing an accurate and precise record of some phenomena. I think for example that an accurate thermometer can measure temperature very precisely, alot more precisely than an amateur birdwatcher walking around with a pair of binoculars identifying and counting birds some morning or afternoon. That is far from being a controlled and standardized measurement that is very precise, Parados, you have to be kidding when you propose that it is? And the kicker to this whole debate is that if the experts cannot even site a weather station according to decent standards, how can you expect a tree hugging Audubon amateur bird watcher to deliver accurate and unbiased observations with a pair of binoculars?
In regard to your ice out on lakes, no I did not look at it, or if I did, I forgot about it, it must not have been very impressive. Post it again and I will look and see if it amounts to a hill of beans.
Now, about wearing a coat to work, I go at about the same time every single day, so if the winter is warmer or colder, I think it might make a pretty distinct mark in my mind, in terms of how cold has the winter been. Look, I am not proclaiming this to be scientifically sound, but it is probably just as good as a bunch of amateur birdwatchers walking around, different people at different times, different people with different skills that identify or mis-identify different birds and count them differently, I do not think such a collection of data should be taken very seriously as regards to telling us much about global warming. It is essentially anecdotal, and besides, populations of birds can also be cyclical in terms of numbers and species, somewhat apart from climatic or weather conditions. Birds are dependent upon many more things than temperature, one obvious one of many would be West Nile Virus. Use some common sense, Parados.
