Reading up at the Mid-Piacenzian Warm Period (mPWP) in the Pliocene epoch cause that's where we're headed. Close analogue to global warming, C02 at ~400 ppm, same solar radiation... Heck, many of the species are still extant!

Animation/model simulation of Antarctic ice sheet fluctuations ~ 5 to 2.5 Ma [#MPWP #Pliocene]. WAIS expands in response to cooling & shrinks as temperatures warm. The model by ARHalberstadt implements time-evolving ocean and atmosphere temperatures,& ties to IODP379 #SiteU1532 sediment core.

I guess I'll just continue to beat this drum until it's through everyone's head - warming (as a response to things like changes in CO2) is not uniform across latitudes!

SherwoodWebb et al assumed a mPWP CO2 of 375 +- 25 ppm (Table 8).
I guess just removing the pliocene (or just lim) doesn't alter the posterior too much (Fig. 22). It's only if you lose all paleo data that the tail starts going up.

Yes. It would be good to get estimates from the mPWP directly.
But fig. 3 doesn't support a huge jump in CO2 b/w 3.3-3.0 and 2.7-2.9 in any of the other proxies.
Going by the bias b/w boron and blue ice, it seems unlikely that extending the blue ice record to 3.3 will give you Co2 > 300

Also during the MPWP, vegetation turnover was high, and intervals with exceptionally high microcharcoal abundance suggest that regional turnover from wooded to open habitats was driven in part by fire. (4/8)

During the MPWP (3.26–3.01 Ma), woody cover fluctuated between open savanna, woodland, and forest formations at typically precessional (19–23 kyr) periodicities, with an overall trend towards more open formations. (3/8)

We analyzed sediments from the 228m BTB13 drill core (3.29–2.56 Ma), capturing the mid-Piacenzian Warm Period (#MPWP) and the onset of Northern Hemisphere glaciation (#NHG). In Africa we see diversification of Paranthropus and Homo and the earliest evidence for stone tools. (2/8)
