I'm not convinced that much colder now, compared to then.*Here on the West Coast ... we have an OBVIOUS beach deposit bench 30 feet above current sea level from 10,000 years ago ... it's colder now than it was then ...
Admittedly things did warm up about 15,000 +/- years ago, when last ice age (glaciation) ended and things began to warm up and melt, but there is also vertical crustal displacement to consider, likely from Juan de Fuca Plate subduction making the West coast of the North American Plate rise.


Meanwhile ocean levels would rise due to ice melt from the last Ice Age/Glacial;

Image here shows approximate areas that would be dry land, dark green, during last ice age/glacial when much water was locked up in the ice sheets(white);

*Also, here's another showing recent temps, and that @ 10,000 years ago would have been colder if not close to same as now.
