I would challenge the merits of that "scientific" analysis because it does not make sense. There are puts and takes in connection with the ice sheets; while they are melting in the arctic, they are solidifying in the antarctic. Global warming peaked out in 1998. How much of the ice is floating? What are their assumptions, data, and methodology to come to such a strange conclusion? Is it political or scientific?
The nice thing about making predictions for the year 2100 is that it’s very unlikely there will still be anybody alive who’ll remember what you said, let alone come back in time and prove that you were wrong.
