Someone flicked a switch there.

Nuttin two sea hee!!!

--
Where to live when the climate goes Silurian.

First of all -- there's +70m of SLR compared to now. That's about 17%
of the US land area underwater. Forget states like Florida.

Anyway, if you live anywhere on the new coastline you're liable to be
hit by annual superhurricanes.

Some models suggest giant storms could become semi-permanent -- kinda
a Big Blue Spot; like Jupiter's Red Spot but a lot, lot closer!

During recent opening salvos of Australia's cyclone season we've seen
one way this might happen. We've seen a couple instances where a
cyclone formed out in the Coral Sea, moved west over the FNQ
peninsula, entered the Gulf of Carpentaria, dropped a 180 and moved
back over the Pen back into the Coral Sea, dropped another 180, moved
west, dropped another 180 ...

So altitudes 70m above current MSL are a must and well away from the
new coastline as well.

But don't go too far into the interior. Climate models and
observations agree that the interior of continents will be subject to
(ha ha) "polar amplification" with warming farm from the coast maybe
2x overall avg warming. The last time atm CO2 hit 2000 ppmv a good
chunk of the land area a few 100 km from the coast was a
superdesert. Few insect fossils are found from that time because even
bugs found the climate a bit harsh.

But you'll be fine!

Again, Australia gives some hints. About 1/3 of the interior is either
sandy, dune or gibba desert. 80% of the population live no more than
100 km from the sea because they need to drink and breathe every now
and then.

Phewt! Puny mammals.

The Silurian was on avg about +9C warmer than now. If you're lucky
that means +12C warmer winters and only +6C warmer summers.
