Its most startling conclusion: sea levels have risen by 6 meters (20 feet) multiple times in the past, and this increase was prompted by a rise in global mean temperatures of only 1?2C.

Yes, during the Eemian it was warmer in some areas but cooler in others and sea levels were much higher than they are now.

At the peak of the Eemian, the Northern Hemisphere winters were generally warmer and wetter than now, though some areas were actually slightly cooler than today. The hippopotamus was distributed as far north as the rivers Rhine and Thames.[3] Trees grew as far north as southern Baffin Island in the Canadian Arctic Archipelago: currently, the northern limit is further south at Kuujjuaq in northern Quebec. Coastal Alaska was warm enough during the summer due to reduced sea ice in the Arctic Ocean to allow Saint Lawrence Island (now tundra) to have boreal forest, although inadequate precipitation caused a reduction in the forest cover in interior Alaska and Yukon Territory despite warmer conditions.[4] The prairie-forest boundary in the Great Plains of the United States lay further west near Lubbock, Texas, whereas the current boundary is near Dallas, Texas. The period closed as temperatures steadily fell to conditions cooler and drier than the present, with 468-year-long aridity pulse in central Europe,[5] and by 114,000 years ago, a glacial period had returned.

But we are nowhere close to matching any of those conditions presently. And that was at the peak of the Eemian. Chances are we have already passed the peak of this current interglacial and we will begin the slow slide back into glaciation.
The .5 degree anomaly that they parrot is based on a "normal" temperature period of about 30 years from the 50's to the 80's. That "normal" temperature is still well below the peak temperatures of this interglacial.
This whole thing is a smoke-and-mirrors poloically driven and motivated shell game.
