Twillingate Icebergs 3











Twillingate Icebergs 3

Most of today's photos show icebergs in the background with houses, fishing stages or people in the foreground.  Those of you who live in different provinces of Canada, the United States or in other countries where you don't see icebergs will probably find these images showing huge chunks of ice so close to shore very interesting. 


The fact that most, if not all of these icebergs came from one giant piece of ice that broke off a glacier in Greenland makes me think about global warming and how glaciers all over the world are melting at an alarming rate.  Last summer a piece of ice 720 square kilometres ( 278 square miles) broke off in Antarctica. Another piece broke off last fall that was almost as big, 660 square kilometres (255 square miles).  Most people don't think about it much, but scientists who monitor the size and location of large icebergs are very concerned.  An increase in melting ice will result in a rise in sea level which will affect most countries in the world.  Hopefully the large pieces of ice breaking off in both hemispheres are anomalies, not a sign of more rapid melting of glacier ice than expected!
