Japan Sinks in 2100 – if we not take enough actions to stop global warming

"Japan Sinking" TV drama now on air in Japan autumn-winter 2021 season. The reality of results from global warming are shown in the several maps (Tokyo, Nagoya, New York, Bangkok, and Boston as examples). 
If we do not take essential actions against climate changes to save the earth, it estimated 3.6 celsius up by 2100. COP26 declared hopeful targets 1.5 celsius up in 2100, however, their real targets from their agreed actions among COP26 participating countries only achieve 2.1 celsius up (We have to wait COP27 and beyond for countries provide additional and more critical actions for carbon-zero). Reality for the future we face seems more severe, because 2.1 celsius up would be achieved only all participating countries meet their carbon-zero goals by 2050. We unfortunately understand politics and people from the human-being history, and we regrettably have to prepare facing the situation our targets are failed, beyond 2.1+ celsius up in 2100. Then what happened in 2100 and people have lands to live?
The sea-level rise map in the year 2100 in the Greater Tokyo area is calculated by World Climate Simulator, En-Roads, developed by MIT Sloan School of Management and many environment activists, United Nations officers, Al Gore and John Kerry use.
"Shita-machi", old district area in Tokyo, will be under the sea level daily in 2100. View from landing airplane in Narita Tokyo airport will be totally different by 10+ times bigger Kasumigaura-lake and Tone River side, looks like new sea emerges. Kawasaki and Yokohama areas beautiful port area will be gone too.</p>

Nagoya, 3rd largest city in Japan and homeland of Toyota Motor Co., will be vanished completely in 2100, if we do not take any action. Bangkok as the same. New York City starts to under the sea level from 2030 in limited area, and will lose 20-30% of their land by 2100. In 2300, our earth will show very different landscape, and Boston town will go under the sea level completely, and my mother schools, MIT and Harvard, should be re-located. But where?
