Not exactly slowly.

That first spike in temperature, called the Bolling-Allerod, coincided with melt water pulse 1A which raised sea about 100 feet. Then the temps dropped back to glacial maximum levels followed by another tremendous rise in temps which coincided with melt water pulse 1B that raised sea levels another 45 ft. and by the time the Holocene had begun sea level had risen 400 ft.

Re: Not exactly slowly

I was referring to planetary average temperature.

Greenland is an outlier that has radical temperature changes based mostly on tropical and Arctic ocean currents.

Thank you for the excellent charts.

I have not seen them before.
