«Modern - day levels of carbon dioxide were last reached about 15 million years ago,» Tripati says, when
sea levels were at least 25 meters higher and temperatures were at least 3 degrees C warmer on average.
Studies of Earth's climate 125,000 years ago find that
sea levels were at least 6 metres higher than today (Kopp 2009).
During the preceding glaciation (the LGM, or «Last Glacial Maximum»), global mean temperature was approximately 6 Celsius degrees cooler,
sea levels were at least 120 meters lower than at present.
During the preceding glaciation (the LGM, or «Last Glacial Maximum»), global mean temperature was approximately 6 Celsius degrees cooler,

Quantitatively, Vasskog et al. estimate that during this time (the prior interglacial) the GrIS was «probably between ~ 7 and 60 % smaller than at present,» and that that melting contributed to a rise in global sea level of «between 0.5 and 4.2 m.» Thus, in comparing the present interglacial to the past interglacial, atmospheric CO2 concentrations are currently 30 % higher, global temperatures are 1.5 - 2 °C cooler, GrIS volume is from 7 - 67 % larger, and global
sea level is at least 0.5 - 4.2 m lower, none of which observations signal catastrophe for the present.
It's particularly important data to get, as you want to know how the whiplashes work in a warm period like today's, when Greenland and Iceland are the main source of North Atlantic meltwater and

CO2 minima were reached approximately when
the sea level was at a minimum, hence, the extent of the continental ice sheets were at a maximum, and the highest CO2 levels were found during interglacials during the high stands of the sea level.
«The Caesarea results indicate that about 2000 years BP
sea levels was at its present elevation, while during the Byzantine period it was at or above its present level by (about 30 cm - plus or minus 15 cm) During the Crusader period «(around 1300AD)» sea level may have been lower than today by about 40c, plus or minus 15 cm.»
Taken together, the average of the warmest times during the middle Pliocene presents a view of the equilibrium state of a globally warmer world, in which atmospheric CO2 concentrations (estimated to be between 360 to 400 ppm) were likely higher than pre-industrial values (Raymo and Rau, 1992; Raymo et al., 1996), and in which geologic evidence and isotopes agree that
sea level was at least 15 to 25 m above modern levels (Dowsett and Cronin, 1990; Shackleton et al., 1995), with correspondingly reduced ice sheets and lower continental aridity (Guo et al., 2004).
Under those conditions, Earth had little ice, and
sea level was at least 60 metres higher than current levels.
