About 90 million years ago, West Antarctica was home to a thriving temperate rainforest, according to fossil roots, pollen and spores recently discovered there, a new study finds.
The rainforest's remains were discovered under the ice in a sediment core that a team of international researchers collected from a seabed near Pine Island Glacier in West Antarctica in 2017.
As soon as the team saw the core, they knew they had something unusual. The layer that had formed about 90 million years ago was a different color. Back at the lab, the team put the core into a CT (computed tomography) scanner. The resulting digital image showed a dense network of roots throughout the entire soil layer. The dirt also revealed ancient pollen, spores and the remnants of flowering plants from the Cretaceous period.
The sediment core revealed that during the mid-Cretaceous, West Antarctica had a mild climate, with an annual mean air temperature of about 54 F (12 C), similar to that of Seattle. Summer temperatures were warmer, with an average of 66 F (19 C). In rivers and swamps, the water would have reached up to 68 F (20 C).
"Before our study, the general assumption was that the global carbon dioxide concentration in the Cretaceous was roughly 1,000 ppm [parts per million]," study co-researcher Gerrit Lohmann, a climate modeler at Alfred Wegener Institute, said in the statement. "But in our model-based experiments, it took concentration levels of 1,120 to 1,680 ppm to reach the average temperatures back then in the Antarctic."

If only we had acted sooner, we might have saved it.

Isn't this what we are doing now? Defrosting the rain forest ...

If the country next door sinks then guess who's coming to stay with you for an epoch or 2?

Just wait for the wall vs Mexico to be done, it's just the prototype for the wall of the north to keep all the hostile eskimoes and Canuck out. The God emperor has thought of everything.
