Iceberg A23a Is Moving

 

The world's largest iceberg is moving. The direction it is going appears to going to the Southern Ocean. Iceberg A23a's movements have been tracked since 1986. Ocean currents are an explanation for the recent movements. There is speculation about climate change and  the relation to iceberg movement. Increased temperature could be causing certain icebergs to break off. Icebergs moving is not harmful. The concern is if large icebergs melt along with an increase  in sea levels. The benefit of the erosion can  contribute to ecosystems in which the iceberg travels. Iceberg A23a could have lifeforms on it. Samples of water from Iceberg A23a need to be examined to confirm this. New knowledge regarding icebergs could revolutionize understanding about the world's coldest regions. Prior to this move Iceberg A23a was spinning in one location. Stuck in the Weddel Sea, is was part of the Filchner- Ronne ice Shelf. The examination of icebergs could be an indirect means of monitoring climate. Icebergs breaking or coming loose is an indication that temperatures are melting some ice. Icebergs of a certain size could be a threat when they melt. Going to warmer waters can result in flooding. If 10,000 A23a sized icebergs were moving, South Africa , Argentina, and Chile would have flooding. The rate in which Iceberg A23a melts gives a proxy measurement of  the rate of climate change.
