Iceberg ahead!!!

Ok woke up this morning and did my usual before getting ready for training, eating my breakfast while looking at the news headlines online. Guess what I read, it might not interest you in the slightest but I thought it was quite interesting. An Iceberg, the size of Luxembourg, has broken off from a glacier in the Antarctic continent. This iceberg measures about 50miles by 25 and contains enough fresh water to supply a third of the world's population for a year! It broke away from the Mertz glacier which is south of Australia after it was rammed by another giant iceberg. Scientists are saying that this massive displacement of ice could impair the normal circulation of cold, dense water. This then normally supplies the deep ocean currents with oxygen. This could have serious implications for marine biology in the region as most of the life there will die!
So this all must be as a result of globing warming, right? The rising temperatures most be causing the icebergs to melt somewhat or causing more cracks to form which as a result causes things like this to happen!! This in turn will cause rising sea levels which as a result could cause flooding in low lying coastal areas. If this were to continue many coastal areas would not need to worry about flooding anymore because they would be completely submerged beneath the ocean! Looks like i'll be stuck in America for longer than expected as I might have no home to go back to in Ireland!!!! Scary!!
