Ocean levels have been rising for over 20,000 years. There was a land bridge between Alaska and Russia. It was the eskimo sleds that caused global warming not volcanos or fires sending out CO2 into the atmosphere. /Sarc.

is that animation correct? the last 4000 years shows no noticeable change?

That is interesting. Our interglacial optimum should be ending soon.
