Dear Aseh,
I have you an extreme example. Four degrees by 2100 is also extreme. Basically science fiction.k prefer to focus on the more imminent part of the issue, but it’s all the same question.
What is the concern?
Miami Beach? For a multitude of reasons, several of which are sentimental, Miami Beach has serious long term viability questions. It also has the potential for high upside. I’m not invested there, so no concern.
Coney Island? NYC is not at sea level. It’s six or seven feet above. It won’t be really threatened by sea rise before the next century.
The rise in temperature in terms of global warming, is not the same measurement as temperature in weather. The difference between the climates of NYC (mostly pleasant summer) and Atlanta (mostly awful summer) is largely not about the difference in temperature.
What is your concern?
