This quote caught me today: "Scientists recently reported that the ice island lost 1 trillion tons of ice mass to the ocean in just four years, between 2011 and 2014." (from here) That change is affecting ocean levels and potentially, if I'm reading this right, "can result in extreme events [in Europe and North America], such as prolonged heat waves, flooding, and droughts, all of which have repeatedly reared their heads more frequently in recent years."
Doesn't it seem like a good idea to take action to address this?
