There was a program on the ABC or SBS last night about the terrible impact sea level rise was having in Florida.

There for all to see were pictures of inundated streets and people wading through water as they go about their lives.

The clear implication was that the sea level rise being experienced in Florida was 100's of mm's, likely 200-300 mm.

Issue ... Sea levels surely can't rise locally due to climate change? I haven't heard of such sea level rises elsewhere in the world.

Alternative view ... might not, for whatever reason, land be sinking in Florida? It is underlain by limestone and limestone dissolves? Continental crust movements ensure some areas rise and other areas fall?

Localised catastrophic sea level rise impacting only Florida to the reported extent makes no sense to me.

atmospheric pressure affects local sea level, so I guess if an area did have a change in climate it would involve changes to the local atmospheric pressure. Not sure of the mechanics but wouldn't high pressure push down on the ocean causing it to rise at the local boundaries?

Maybe this is what they are talking about.
