I confess that I’m not an avid follower of news when it comes to climate changes or weather, but recently I was thinking about Global Warming and more specifically the polar ice caps. The query I pondered for a moment or two was whether or not the ice caps were in fact really melting at all and if it was true, what would be the outcome of it? The following is the information that I found in seeking to find an answer to these questions.
Polar ice caps and icebergs should need no introduction, but for those that may not know, a polar ice cap is a high region of the planet covered in ice whereas the iceberg is a large floating chunk of ice that dislodges massive volumes of water that is often as heavy as the iceberg. As for whether or not both of these play a substantial role in the rising of ocean levels, so far it seems there is just enough distinction that can be noticed.
When the earth’s temperature rises in considerable ways, mores icebergs begin to form because of the weakened polar ice caps. Cracks begin to form and the result becomes the breaking off of ice which will then slightly increase ocean levels in much the same way as when you put ice into a glass of water and watch it rise. So because the earth’s rising temperatures affect these polar ice caps and create icebergs, many people have still been asking the question: Could many of the polar ice caps be in peril of thawing out and increasing the world’s sea levels? The answer is that this can most certainly be the case, but nobody can know exactly when it will occur. [Read more...]
