In 2017, a massive iceberg drifted past a town in Newfoundland at a whopping 15 stories above the water. This number is especially large when taking into consideration that the tip of the iceberg is only 10% of the entire mass of the iceberg. It’s not uncommon for icebergs to float by Canadian shores, but lately more and bigger icebergs have made their way south, calving off of Greenland. This is concerning, as a rise in temperatures (in part due to rising green house gas emissions) means that glaciers are shrinking. With glaciers melting and calving off more and more icebergs, the sea level is set to rise as well, meaning that icebergs won’t be floating past Canadian shores, they’ll be floating over them. Also concerning is the inconsistencies in how many icebergs calve annually, with 1,546 icebergs clogging shipping lanes in 2014 (one of the top 6 most severe cases in over 100 years), and only 687 icebergs 2 years later in 2016. GHG have real effects, and more needs to be done to reduce them.
