I think the single biggest growth industry (heh) will be food production. All those people living on the coastlines will have to move inland, and we’ll be losing a lot of farmland. Also, if the predictions are correct, the farmlands which aren’t affected by the rising sea levels will have a harder time getting enough water for irrigation. And don’t forget- with the rising sea levels, existing ports will be screwed- so foodstuffs will be harder to import.

Sea levels will rise- but not so much.

"The current rate appears to be almost 2mm a year, or 15 or so years to raise the sea level one single inch.

That rate is disputed and unclear:

Global mean sea level is a potentially sensitive indicator of climate change. Global warming will contribute to worldwide sea-level rise (SLR) from thermal expansion of ocean water, melting of mountain glaciers and polar ice sheets. A number of studies, mostly using tide-gauge data from the Permanent Service for Mean Sea Level, Bidston Observatory, England, have obtained rates of global SLR within the last 100 years that range between 0.3 and 3mm/yr, with most values concentrated between 1 and 2 mm/yr. However, the reliability of these results has been questioned because of problems with data quality and physical processes that introduce a high level of spatial and temporal variability. Sources of uncertainty in the sea-level data include variations in winds, ocean currents, river runoff, vertical earth movements, and geographically uneven distribution of long-term records. Crustal motions introduce a major source of error. … … Furthermore, not all climate models are in agreement. Opposite conclusions may be drawn from the results of other GCMs. In addition, the West Antarctic Ice Sheet is potentially subject to dynamic and volcanic instabilities that are difficult to predict. Because of the great uncertainty in SLR projections, careful monitoring of future sea-level trends by upgraded tide-gauge networks and satellite geodesy will become essential. Finally, because of the high spatial variability in crustal subsidence rates, wave climates and tidal regimes, it will be the set of local conditions (especially the relative sea-level rise), rather than a single global mean sea-level trend, that will determine each locality’s vulnerability to future SLR. "
So, if the rate is 0.3mm/year, it’d take nearly 100 years to raise one inch. At the highest current estimate, it’d take 8 years to increase one inch.
Coastal areas will not flood- not in the time most dudes would consider a normal investment period.
Now, if you were going to invest for your Grandkids, then maybe. Assuming then a 25 year investment period- sea levels will rise 3 inches.
Don’t get me wrong- Global Warming is a serious problem. But the sea level part of it is mostly extremely long term and extremely speculative.
