The 3atm air with more CO2 pressure spread better the temperatures through the planet, so the equator is colder and poles are hotter. The extra air will make flight easier and more oxygen mean more energy, so stronger and smarter animals. There's still ice on the mountains and interior of Antartica and on the mountains near the Artic Sea.
I think this Earth (Waskn'Narax) is better because more land means more fertile areas, more places to explore and extract minerals, fuel and for humans and animals to live. Even with much more land than water, there's still too much water, even for whales. There are 2 oceans and many isolated seas. Isolated seas mean more variety of aquatic animals. In Waskn'Narax, there are other intelligent animals, such as dolphins, small whales (both with fingers on fins), chimps, Homo Sapiens Sapiens and Homo Neanderthalis, and some species of avians such as megaparrots (all with fingers on their wings).
This map is of an alternative version of our Earth, not a truly extrasolar planet. Even the Solaris System, where Waskn'Narax is, is an alternative version of our Solar System (a better one) with more planets.
The lands are of Waskn'Narax are: Artica, Gringolia (North America), Caribea (Central America), Andea (South America), Nazca, Antartica, Pacifica (Australia), Zealandia, Atlantis, Lemuria, Kerguelenia, Himalayasia (Asia), Saharasia (Saara), Congonia (Sub-Saharan Africa), Indiania, Europe and Borealia.
Now my question is: Which do you think it's better, our actual Earth or Waskn'Narax? Think of the advantadges of such extra fertile lands...
