I don't understand what is it about climate science that everyone seems to think they're qualified enough to have strong opinions on. I don't see random people commenting on the intricacies of CPU design, battery design, petrochemical processes or any other high-tech endeavor, but with climate everybody's a f*cking expert.
I hadn't heard of an estimate of being ice-free by 2020-21. Per this recent National Geographic source, it is likely to happen as early as 2035.

That aside, many of the other comments here, filled with deep existential dread about our future world, are straying into the manic given how terrible humans are at predicting anything at all over the long term. There are far too many unknown unknowns for us to be sure of any aspect of catastrophe for 2100 or even for earlier years. Never mind years beyond 2100.
It should serve as very serious food for thought just how much reactions to COVID by public officials, scientists and the media as well were bungled, confused and fraught with false claims (notable examples: masks don't work, the virus has a 1-3% mortality rate) in just a single year because of science and politics mixing heavily in a media charged atmosphere. Yet somehow, the far, far more complex theme of global climate patterns over decades combined with human trends during the next 70 years, is taken as a near given of planetary catastrophe to the point where many of you are firmly convinced that having children now is barely a step below slow murder...
