Global Warming..?

Ok. After 3 months of balmy winter weather I'm starting to think there might be something to this Global Warming talk.

Is the ozone layer shrinking?
Are ice caps melting?
Is the water level rising?

I have no clue. I'm not a scientist. However I spent Sunday at the park in 60 degree weather on the last week of January!

Am I going to one day reminisce before my grandkids about how it used to snow in these parts..years ago?

But on the other hand..whenever I hear the weather report they always add..
This is the warmest winter since 1952

and so I wonder..did they fret about Global Warming back in 1952 as well?
