What wiser wondered is why Asuka expect mankind to have survived N4I when N3I, which was stopped as quickly if not more than N4I, is said by Kaworu to have obliterated the planet and destroyed almost all the biosphere.
That's why I said that it was another hint that something else after N3I happened between the end of 2.0 and 3.0 that left the world in the sorry state we saw it in Q.
EDIT : 
In the Flood Maps topic, NemZ made this comparison map of 2I's vortex and the Antartica :
So according to that map, the center of the 2I vortex is located on the Amundsen–Scott research station, which is located on the Geographic South Pole, the southernmost place on Earth.
I also noticed that the vortex stops exactly at the Antarctic Circle 66° 34'S., which means that the 2I vortex is approximatively 5000km of diameter...
So that pussy 20km wide N3I vortex is supposed to have been more destructive than a 5000km wide!? WTF?
That location also raises a lot of questions : assuming that the center is the place where the four ADAMs were frozen, and thus where the Katsuragi Expedition had its base, then Dr Katsuragi was really unconscious to bring his daughter in that place which is of the most dangerous on Earth, and more importantly, the base is situated at a good 1500 km of the nearest coastline, so how the fuck Misato and her emergency escape pod ended in the sea!?
The only explanation I could think of is that the ADAMs were located not in the Geographic South Pole, but somewhere near the coastline, and that the bigass vortex opened not above them, but above the White Moon (or the Rebuild equivalent, let's call it White Moon for simplicity sake), which is located under the Amundsen–Scott research station (which could had been a covert SEELE base)
That raises a possibly important implication : what if while it's a SoL/Awakened Evangelion which starts the Impact by opening a small Door of Guf above its head,
it's actually the White/Black Moon that opens the giant vortex to give it a planetary range!Think about it : in 2.0 EVA-01 first opens a "small" vortex above its head :

then all of a sudden a big one opens just above the surface, ripping open the Geofront

Which extent to have a diameter of a good ten kilometers :

Since EVA-01 was just under, we assume that it's still it that opens and maintain that vortex, but maybe it only directly opened the small one above its head, and then the Black Moon reacted to it as an activation signal and opened a much bigger Door of Guf.
In short, the SoL/Awakened Eva open a small vortex, which make the nearer Moon react and open the big Door of Guf, which the SoL/Eva will use to do whatever terraforming/Instrumentality it wants.
When Mark.06 impaled EVA-01, it interrupted the activation code emitted by EVA-01 or sent a deactivation signal, which made the Black Moon stop keeping a giant Door of Guf opened.
That theory would explain many of the events surrounding the KE and 2I : they find the four ADAMs near the coastline, awake them, they make a small vortex above them, which activated the White Moon a couple thousands kilometers away. For some reason, the Door of Guf is much bigger than N3I seen in 2.0 and 4I in 3.0, maybe it's because there was 4 catalysts instead of only one, or maybe the WM was in better shape than the BM, or maybe the WM is just more powerful.
Anyway, as in NGE, something goes very wrong (or very right for SEELE), everything explodes and the four ADAMs ends flying away, one of them ending on the Moon, and 2I is interrupted. Yet for some reason the vortex above Antartica is still open, why?
I have two possible explanations :
- One (or more) of the ADAMs wasn't as damaged as the others and was still emitting an activation signal to the WM, but since it wasn't under the WM range anymore, it couldn't use the DoG to continue the terraforming process, leaving only a giant DoG opened for nothing above Antarctica. But that raise the question of why didn't that Angels tried to reach that ADAM instead of Lilith.
- assuming that a spear + deactivating SoL/Eva = deactivation signal, the big explosion that KO'd the ADAMs prevented the emission of a deactivation signal, leaving the WM still generating a DoG. That would explain why the Door is still open yet all terraforming stopped.
In 3.0 the case was slightly different : EVA-13's Awakening happened inside Lilith's Camber, at the center of the BM, so it's possible that it made the activation signal immediately reach the BM, explaining why a big DoG was opened immediately when EVA-13 reached the sky, without passing by the "small personal vortex" phase. That would also explain why the BM suddenly decided to emerge from the ground and float under the DoG : it was activated by EVA-13. Notices that the ruins of NERV HQ and the main shaft being several kilometers above ground already hints at the BM having begun its emergence earlier, certainly during N3I and/or whatever happened with the 12th Angel and Lilith.
Somehow, I can perfectly picture the WM gently floating above the antarctic ground, still generating a DoG, since 2I.
Anyway when EVA-13 impaled itself with the two spears and Mari ejected Shinji, deactivating the Eva, it reached the two conditions to send a deactivation signal, deactivating the BM, which stopped opening the DoG and crashed back on the ground.
It's also possible that the KE only found one of the ADAM in Antarctica, and upon awakening it from its slumber, it called his three pals who joined him and started Second Impact.
Assuming that the KE did the same thing than in NGE (injecting human DNA in the SoL to make the Forbidden Union) and that the Key of Neb is one of the ADAMs, that would explain why one of them was reduced to that small thing while the others were still intact upon finding : only one of them got the "Forbidden Union treatment".
