Salinification is one of main vectors of change from sea-level rise:
Ground-water becomes brackish
Existing flora dies and may be replaced by salt-tolerant species
Does raising the course protect against this? Are there other techniques, such as salt-tolerant grass strains?
Here's a list from Business Insider of populated areas at risk of flooding. Some golf areas to reflect on:
- Miami Beach
- Atlantic City
- Hilton Head
That article cites predictions of as much as 8 feet of sea level rise in the next 80 years based on 2017 rates. If all the Antarctic ice melts then the new "steady-state" sea level would be about 200' above today's levels.
Pro-tip buy up that land at the 200' mark now, you're great-great-great-great-great-grandchildren will thank you for the waterfront property. And they say no one's making more waterfront property! Bah!
