.. has hit media recently so let's take a look here: ITGC Thwaites Glacier Thwaites glacier melt is now raising sea level by about 2 millimeters per year (within total 3.5 to 4 mm/yr). If it all goes, would increase sea level by 65 cm. Ice guys think that could happen in about 2 centuries. Other ice contributes to sea-level rise but all taken together seem unlikely to raise sea level by > 1 meter by year 2100. That's not enough to trash most global commercial ports (but maybe a few). It would be enough to harm ~ half billion global residents, mostly poor people. Most important here is that oceans have already been warmed by +CO2. Holding that line at current level will not prevent it. Baked in. == Separately we could consider west Antarctic ice sheet mostly held back by Thwaites. It melted has ~ 3 meters of sea-level rise, but would require more centuries. Most other Antarctic ice looks very stable now see link above. == Other things that future +CO2 can do, including +T and increased climate variability could be limited by not making CO2 higher. They have much shorter time controls. I think it merits attention, what we can or cannot do.
The planet is moving off its axis. Where there was always heat, now it snows. Melting glaciers are falling on the lands of the African continent.

Oh bother.
Where the Murray River passes through Mannum, South Australia, where we live, it is 750mm above the AHD (Australian Height Datum) sea level at the moment, yet it still has 150 kms (95 mile) still to flow till it reaches the ocean. Just one example of how far inland, any ocean rise will cause flooding without a rain even to increase the river level. Even a 50mm rise (2") will cause flooding up and down the Murray River. Where the Darling River joins the Murray, the river that drain most of inland Qld to the sea, is 30 mtrs above sea level yet 990kms by river from the sea. When it rains a lot in NSW inland of the mountains, the Murrumbidgee River floods and that empties into the Murray 1,090kms by river before it reaches the ocean. This is the most common flooding that causes flooding all the way down the Murray River, raise the sea level even 2", and a lot of land that is above water at the moment, wouldn't be any more, simply because the effect it would have on the river flow. There must be thousands of similar cases world wide, it isn't just those on the coast that will be affected ..... but it will be the mineral rich farm land beside these major rivers that will be lost ..... that is a serious world food supply risk .... no one seems to consider that part, without all the people who will lose their homes, roads that will be no ,longer useable ....... Venice has already seen major walking areas become flooded more often and take a lot longer for the water to recede ... they fully understand a time will come when it doesn't recede enough for that area to be above water level. Holland is already below sea level, things will get serious there very soon ..... T1 Terry
If you packed all that snow into a container and heated it till it melted, there wouldn't be a lot of water recovered. If that snow was to remain for a mth, that might be significant, but you can see by the complete lack of chains on any of the vehicles, this was a freak even, not the new normal. T1 Terry
I'm thinking 14 ft (4.25 m) would be an excellent gain in sea level rise. However, storm surges reduce how much is needed. I would morn the loss of Kennedy Space Flight Center. Bob Wilson
Our house would have absolute water frontage, actually all round water views, tie the boat up to front patio railing, car and motorhome would be useless, but a houseboat ...... with that much water, we could go anywhere .... but a bit like Water World, besides even more ocean, what would there be to actually look at ..... the trip down off the mountain in Adelaide would be one of the most exciting water sliders ever T1 Terry
