It's also not the same thing as saying that human civilization will cease in 12 years. There's a difference between "too late to change course" and "the end".
Feel free to share your calculations of the amount of ice and how much ocean water will rise.
Perhaps you'd suppress your snickers a bit if I got your experts to describe their calculations.

hmmmm….
This is only the Arctic, with nothing about the Antarctic here. 3800 cubic miles of sea ice in the Arctic Ocean. Niney percent of which is "under water" unless it's sitting on rock.... 3.8 million square miles if you spread it out 5.2 feet deep. Ocean surface on Earth is about 139 million square miles. oh, so about 2 inches in sea level rise if all that melts. uhmmm except 90% is already part of the ocean volume.... so how about 0.2 inches.
Supposedly, The Antarctic is having winter when the Arctic is doing summer, so as ice melts in the North, it is freezing in the South. But the article claims a 25 cubic mile loss this year. A year to year difference of 25/3800 times 0.2 inches. say....0.002 inches.
Of course, there is the huge ice shelf in the south, plus all the landlubber ice of the south, plus Greenland, and the glaciers....

This article claims if all the ice melts, sea levels would rise about 200 feet. I worry about the Delta chub between Stockton and Fairfield. A lot of the fertile Central Valley, gone. Just the tops of the hills in San Francisco. Silicon valley gone.
hmmmm……. wanna help me melt the ice???? I could make the case we need to do it to save the planet...… No more New Orleans, Mardi Gras or not..... no more LA.
yah.... so people will move. Trump will build new towns. full employment. Lots of tax revenues.
seriously, almost all of earth history has been without any permanent ice. So what does "normal" really look like????
I don't think we need CO2 to melt the ice. I think a cyclic decline in solar inputs is outweighed by a cyclic increase in Earth heat generation in our near future.
Instead of economic totalitarianism, eliminating opportunity for the peasantry while demanding they sacrifice for the sake of social justice while the Fatcats build their bunkers in the Rockies, the best thing we can do is just start building on higher ground. Look for new areas to do agriculture, find other resources.
I will have lakeshore estates when that happens, if anybody is interested.
