  •  Well, lets do the math! (9+ / 0-)

    Assuming all that melt came from non-sea ice and although there are some differences in the density of salt/fresh water and from temperatures they're fairly small at the temperatures we're talking about. The ocean's surface is approximately 361,000,000 km2.

    4T tonnes of water spread out over the whole ocean amounts to about 11,100 tonnes/km2. But if you reduce it down further you'll see just what that means in human scale terms.

    11,100 tonnes = 11,100,000 kg
    1km2 = 1,000,000 m2

    So we're now dealing with 0.0111 tonnes/m2 or 11.1 kg/m2. The density of water is 1g/cm3 which lets us calculate how deep that 11.1 kg of water would be spread out over a square meter. The answer -- 1.11 cm (11.1 mm) of water or a little more than a third of the entire 32mm change. So, yeah, that's definitely part of the problem.

    To me progress is not so much a goal as it is a process and I believe it will not follow a straight course. Remember, the drops of water that form the river may not take the shortest path but they will still reach the ocean.
