How could it have been so warm without human carbon emissions?

For anyone who says the science is settled, then there is this:

Antarctica as we know it is a frosty wilderness covered in thick compacted ice.

But a recent scientific discovery suggests that the vast white continent was home to leafy forests, some 280 million years ago.   

During the last Antarctic summer, geologist Erik Gulbranson and a team of polar scientists chanced upon fossils from the oldest polar forest found on the continentbefore the first dinosaurs walked the Earth.

Now the team is braving the land of ice once more to uncover clues as to how forests once flourished there.

Antarctica was much warmer 280 million years ago than it is today. Back then, it was still part of Gondwana, the Southern Hemisphere supercontinent that incorporated present-day Africa, South America, Arabia, India and Australia.

According to Gulbranson the southernmost part of the continent would have been carpeted in seed ferns extending up to 40 meters tall.

These trees would have been able to survive approximately four to five months of absolute darkness, followed by four to five months of continuous light.

However, their rings reveal a high frequency of very bad years of growth, says Gulbranson, suggesting it wasn’t an easy environment for these trees to live in.

How could it have been so warm without human carbon emissions?

It shows that claims about warmest ever are pure unadulterated bullshit.

In studying tree rings on fossils from before and after the extinction, Gulbranson surmises that only one species of tree existed in this carbon dioxide rich ecosystem prior to the extinction.

After the extinction, he says there was less carbon dioxide in the atmosphere, a higher diversity of evergreen and deciduous trees and a much more stable ecosystem.

Gulbranson says his work could help us understand the effects of contemporary climate change.

He says modern-day global warming may lead to forests migrating towards to the North Pole, in places like Arctic Siberia and Arctic Canada.

“We know there’s some connection between the gas concentration in our atmosphere and the types of ecological health that we might expect to see on our planet,” he says.

Surely forests expanding is good news?

It just goes to show that the science is not settled. It was clearly warmer in the past than it is now, so warm in fact that massive tree ferns once lived in Antarctica.

As much at home writing editorials as being the subject of them, Cam has won awards, including the Canon Media Award for his work on the Len Brown/Bevan Chuang story. When he’s not creating the news, he tends to be in it, with protagonists using the courts, media and social media to deliver financial as well as death threats.

They say that news is something that someone, somewhere, wants kept quiet. Cam Slater doesn’t do quiet and, as a result, he is a polarising, controversial but highly effective journalist who takes no prisoners.
