Recently there has been much clamor about the shrinking of the Northern Ice cap. You can even view the ice sheet coverage over the last 28 years. Indeed I was suprised to see that post summer ice coverage steadily decreased across the late 80's and nineties. (See for yourself here)
But then I discovered that the Southern ice cap which covers Antarctica has steadily been growing over the same time period while also reaching record low temperatures.
Now I'm no earth climate scientist but something's a little funny here.
The proposition of Global Warming posits that the atmosphere of the earth is warming due to increased emission of green house gases like CO2, methane, NO2, water vapor etc.
This may help (if Gobal Warming theory could show that increased atmospheric temperatures directly result in increased land temperatures) to explain why the North Pole is shrinking. It could also explain melting glaciers.
However, the Antarctic growth seems a rather large piece of evidence to the contrary. Global Warming theory does also posit that as a result of increased atmospheric temperature, water retention in the atmosphere is also increased. Perhaps there is an increase in snow fall over the Antarctic continent. But then why isn't the Northern ice cap increasing as well?
I hate to be pessimistic, but perhaps either the global part of the proposition is lacking...or perhaps something else is going on.
Perhaps it's as simple as natural variation in weather and solar output. Perhaps it has to do with the fact that increased particulate output from industry worldwide has shifted weather patterns across the globe, bringing snow to the Antarctic and dry air to the Arctic. In fact, maybe a shrinking Arctic ice cap has nothing to do with Global Temperatures.
Whatever the explanation for the melting/growing ice cap phenomenon, it's important to keep in mind that there are other humanitarian struggles in the world. Going green is not the solution to the world's problems, though it may alleviate some of them. (I still like being green though...it's a good hobby)
