A-23A Iceberg on the MOVE

World's largest iceberg (currently on earth) has just freed itself from a 37 year spin-cycle near Antarctica.  Breaking off of the Filchner shelf in 1986, the berg called A-23A was hung up on probably some underwater ridges in Weddell Sea.  For over three decades researchers watched it just spin about and finally late last month it broke free and it headed to open waters to melt.  The click-bait articles talk about it crashing into habited islands, or wrecking sea life on islands in the Southern Ocean, or getting into sea lanes.  I think the stories about it going into the shipping routes are a little sensationalized, because the iceberg is bigger than the island of Malta.  Not likely a ship won't notice it.  This iceberg, the largest on the planet right now is not the largest ever.  There were previous ones which were bigger.  The event this month raises the question- are we just able to see these bergs better with advanced tech?  Or are these big bergs breaking off a major new development in climate change?  No doubt climate change has a part in this, but to what extent?  Are we going to see more and more break off at an increased rate?  Great questions for kids to study in class, and since it's a current event, worth checking out.
