Global warming, yea or nay? While politicians seem to argue about its reality more than any other group, we common folk have been known to joke about it. When we have exceptionally cold weather (like at one of Al Goreâ€™s conferences a couple years ago) we point at it and say, â€œHey look! More global warming!â€ Just recently I saw an article that global warming would cause the (north) polar ice caps to melt, which would release more fresh water into the Atlantic, which in turn would affect the Gulf Stream in such a way, that Europe would become much colder. Have you ever seen a study more ready-made for jokes: â€œGlobal warming leads to global cooling.â€
Personally, I think itâ€™s a language problem.
Instead of talking about â€œglobal warmingâ€ we should talk about â€œhuman induced climate change.â€ Although I must confess that Iâ€™m not a scientist and have taken no courses in meteorology, I do know enough to recognize our atmosphere (the place weather happens) as a complex system. A small tweak in one place can produce large (unpredictable) changes elsewhere in the system. Thatâ€™s known as the â€œButterfly Effect.â€
If we change the discussion from â€œglobal warmingâ€ to â€œhuman induced climate changeâ€ then a much broader amount of data comes into the picture for us ordinary folks.
