How will global warming affect countries like Iceland on a long-term scale?

    I believe you might be talking about Greenland, that’s the country that is composed mainly of ice; while Iceland (ironically) is not composed of any ice. 

    Greenland is composed of 80% ice sheet. Since 1995 Greenland has lost 265 cubic kilometers of ice a year (on average) due to atmospheric warming. It is thought that 25% of global sea-level rise in the past 13 years has been from Greenland ice sheets. It is projected that by 2100 Greenland’s loss of ice mass will be near 650 cubic kilometers annually. 

    Given that the total area of Greenland is over two million square kilometers it will take a long time before the country has lost a proportionally substantial amount of land mass, but the results of steady fresh water run-off on the global sea-levels will be a problem.

    Countries like Iceland will face their own problems due global climate disruption.  Iceland’s climate is far milder than one might assume despite its proximity to the arctic circle.  Iceland receives warm ocean currents known as the Atlantic thermohaline circulation that pumps water north from the Caribbean, up the eastern seaboard of the United States, and northeast toward Iceland.  These warmer waters bring a much more livable climate compared to other locales at the same longitude.

    When Greenland’s ice sheet melts, it adds small amounts of cooler water to the North Atlantic; if enough glacial melt water is added to the Atlantic thermohaline circulation, it will stop the current all together.  Iceland’s climate would change in a matter of days which would spell disaster for the entire country.  Food production would come to a stand still and the once livable climate would become harsh and frigid.
