I laugh at all the people who say "Wow it's cold....Global warming must be over".

One has to look at the long term effect. For example I was watching a show about the Titantic last night and they talked about the Ice patrol. These are people in airplanes using sonar and radar who are looking for icebergs in the shipping lanes. Well, here lately those people appear to have a lot of time on their hands. In some recent years no icebergs have made it down to the shipping lanes.
