Yeah this is really no big surprise. I live in Yukon territory in Canada, and they have found fossilized palm trees here. Not to sure in my opinion that the climate was ever like that here, but maybe it was, could have also been the drifting of the continents aswell, places werent in the same spot they are now.
Before these people worry about "palm trees" growing in the Antarctic, they might want to see if they can even get conifers from the Arctic to even live there. My understanding is that there are only two higher plants that live in Antarctica, once species of grass and one plant from the daisy family, and they only grow in the warmest coastal areas.
More global warming alarmism. Many things could happen, we may have another ice age, who knows.
One thing that is not clear here "in the Antarctic Region" means nothing at all. Just what and where is this region? "Palm Like " trees? do not confuse this with Tropical Palm trees that we know of, because the earliest trees were all "Palm Like" no matter where they grew.
One thing that is not in doubt, is the higher levels of CO2 in the Eocene period, levels that may be returning. Human society is not prepared, or even able to react to this scenario, no matter how advanced they may think they are.
