One big headline that Germany’s online tabloid Bild carries today is about the breaking off the Antarctic Pine Island ice chunk, which is the size of Berlin…880 sq km!
Bild calls it a “Monster Ice Berg!” and of course we are to believe that it is yet the latest sign of the coming climate apocalypse that we will all suffer unless we all run and hide under our beds and beg for mercy. According to Bild, the giant ice berg is about 60m high.
Simple mathematics tells us the volume is about 53 cubic km.
Bild mentions, quoting scientists, that such glacier calving of this magnitude is normal, and occur about every 10 years or so. But normalcy is not the message that Bild wants the reader to get, and so warns that the “monster iceberg” could pose a threat to shipping, and to animal life! Bild also says that scientists are deeply worried and writes:
The Pine Island glacier is huge and unstable, and thus it is difficult to judge the risk for global sea level rise.”
Such stupidity – of course aimed at quite uninformed, clueless readers, to say it diplomatically. How much global sea level rise should we expect? From various sources we can read that a large part is already underwater. But let’s assume that none of it is under water just for the calculation.
Sea level rise estimation:
Area of oceans: 362 million sq km
Volume of Pine Island chunk: 53 cu km
Sea level rise: 53 km3 divided by 362,000,000 km2 = 0.000000145 km = 0.000145 m = 0.145 mm = 145 microns
Given that much of it is already submerged in sea water, we can safely assume that sea level rise will be less then a tenth of a millimeter.
Quick – head for the hills!
