The rising sea levels won't affect everyone, right?
Wrong. Many would think that simply living a couple of hundred meters above sea level makes them safe, however, they would be wrong. Your living area may not get flooded but the water itself is the smallest part of the problem. Seas influence climate, which can change dramatically under new circumstances. We get most of our water from freshwater sources and they are also constantly degrading. So, in fact, everyone will feel the consequences of rising water levels.
How much exactly does the sea level rise?
People have been measuring sea levels during the twentieth century, and we can look back on that livejasmin data. According to what our predecessors have gathered, sea levels have been rising 1.8 mm. per year during the last century. These days, scientists utilize satellites in order to research the ocean surfaces. Since 1993, sea levels rose for about 3.3 mm per year, that's twice as much as before.
Why do the sea levels rise?
Some think that this is a part of some kind of cycle. Truth is, we don't have enough information to confirm that. However, there is also solid evidence that the rise is occurring because of global warming. Research showed that more than ten years ago, sea levels rose because of water expanse due to warmth. These days, however, roughly 80% of the rise can be attributed to melting glaciers. According to research done by the GRACE mission, the Greenland ice sheet declines by 150 gigatons ( 150 billion tons) each year. Ice from Greenland and Antarctica causes a water level rise of 1 mm. per year.
In conclusion, not much is know about just how rising sea levels will affect our homes or, in a wider sense, our planet. The human race has never recorded such an experience so we'll have to wait and see.
