Hank, They report the news. Try and find a unbiased media outlet may be tough, but what would I suggest is research and reading. With the internet today its so easy. I haven't gotten into so much as far as reading but so far what I read shows temperatures in the Arctic are changing. Im not talking about a unusual hot summer in Alaska but changes in sea levels and stuff like that.
As a kid we use to look forward to ice skating and sledding. It was winter and we loved it. I cannot tell you how many years its been since the local pond in a nearby park froze over enough to ice skate. Its been at least three decades. The harbor on the south shore of the island often froze over, not every winter but with a cold winter it happened. The last time I recall it freezing over was the winter on 1976/77.
To completely deny and Global warming is really being kind of blind. Not to say I agree with tree hugging alarmist's but there is changes and its a direct relationship to our environment and how we treat it.
A little off subject is pollution in our water ways. The New York harbor was filthy at one time, now its vastly improved with strict environmental regulations. Ive witnessed it myself.
