Loss of glacier would imperil coastlines worldwide

2. Wait until they find out that the shoreline of the US coast that abuts the Gulf of MEXICO

is predicted to be among the worst hit by climate change, and that the rate of the rise in sea level is already higher than most of the rest of the USA. A few keys facts (from AI, take from this as you will):

Low elevation and subsiding land
More than 7,000 square miles of the U.S. Gulf Coast lie below 5 feet in elevation, including major urban centers and infrastructure nodes like Houston and New Orleans.

Large stretches of the Gulf Coast are subsiding due to groundwater, oil, and gas extraction, plus wetland loss—so relative sea‑level rise (water up + land down) can be equal to or greater than the global average.

This combination of low elevation and subsidence makes the region extremely sensitive to both chronic “nuisance” flooding and catastrophic storm‑surge inundation as sea level rises
