Antarctica was covered in rainforests when dinosaurs roamed Earth

The researchers estimate that carbon dioxide levels in the atmosphere were well over 1000 parts per million in those days, compared to 400+ ppm today. Antarctica and Australia were much closer together.

Antarctica was covered in rainforest in the time of the dinosaurs, according to a new study, Metro News reports.

Researchers have found evidence the South Pole had a climate and forests similar to New Zealand today in a startling discovery. The team discovered soil from an ancient rainforest from the Cretaceous period within 900 km of the South Pole.

The analysis carried out by an international team of researchers of roots, pollen and spores shows the world was a lot warmer than previously thought.

Professor Tina van de Flierdt, from the Department of Earth Science & Engineering at Imperial College, London, said: ‘The preservation of this 90-million-year-old forest is exceptional, but even more surprising is the world it reveals. ‘Even during months of darkness, swampy temperate rainforests were able to grow close to the South Pole, revealing an even warmer climate than we expected.’

The heyday of the dinosaurs was the warmest period on Earth in the past 140 million years, with temperatures at 35 degrees and sea level 170 metres higher than today.

Despite the Antarctic Circle living through a four-month polar night, researchers discovered evidence it was once a temperate rainforest. The evidence for the Antarctic forest comes from a core of sediment drilled into the seabed near the Pine Island and Thwaites glaciers in West Antarctica.

    This isn’t new, as BBC was covering the [climate] change in a program a few years ago. It was broadcasted in Swedish national television (SVT Kunskapskanalen [‘Knowledge Channel’]) last year, despite the PC sensorship we have here.

    In the program, they went even further and informed that the tropical climate was shared with Australia, when both once was one single continent. When they broke apart, the surrounding ocean currents and the climate changed on both continents as a result. Before the break, Australia had a great lake, that today is an underground reservoir. Obviously, the two continents shared the same fauna and flora.

    Since the break, Australia is moving toward South East Asia [SEA]. One of the islands in Indonesia share the ground composition with Australia, different from the rest of SEA.

    Anyone want to say why and how? Hint, 5 bar and one ‘hadley’ cell.

    My own unproved theory is that the penguins, with their entirely stupid lifestyle (at least some of them), orginated on the continent back then and have evolved as Antarctica drifted southwards. Thats why the Emperors “nest” in such a dumb location, because thats what they did when Antarctica was warm and forested.

    Where they think Antarctica and Australia used to be…

    Say what you like about Emperor Penguins, at least they aren’t Adelie Penguins

    Are they trying to say that the world isn’t going to burst into flames if it gets a little more carbon dioxide in the atmosphere or is this the start of the rowback of the ‘we are all doomed’ cult?

    “Antarctica was covered in rainforests — ” when there were glaciers at the equator.

    Obvious why, but that is one big heresy.

    Somewhat hard to believe. But then again…

    A third of a billion years ago, Ireland was located south of the equator.

    I remember being taught this at uni 30 yrs ago, so I cant see what is new about this, other than new evidence of what was already theorized.

  10. oldbrew says:

    Jane – presumably ‘an even warmer climate than we expected’ is the new thing, or one of the new things?

    Philosophers want to know: If Antarctica was not in the Antarctic, was it still Antarctica?
