Damn Fred Flinstone and his Fred mobile causing climate change.
The first frog fossil from Antarctica has been found
An ancient amphibian from Antarctica gives new insight into when the continent got so cold.

And how could the climate drastically change without humans?An article for children. Perfect for this thread.

The first large ice caps form as Antarctica settles its position over the South Pole. This is thought to be partly due to the planet's climate becoming cooler as carbon dioxide level in the atmosphere fall.
I still have that action figure.
Then I blame you!I still have that action figure.
I have broad shoulders. Go right ahead.Then I blame you!
LOL So speaks massive ignorance. Let's count the ways. Comet or asteroid impact. Movement of the tectonic plates. Massive volcanic eruption. Drawdown of CO2 from an orogeny. Drawdown of CO2 by rapid plant growth. But none of these are happening at present, but we know how much GHG we have put into the atmosphere.And how could the climate drastically change without humans?
Ah. So frogs are in Antarctica and palm trees in Alaska because of volcanoes.LOL So speaks massive ignorance. Let's count the ways. Comet or asteroid impact. Movement of the tectonic plates.

Depends. The massive Siberian Traps cooled the earth, then, when the aerosols settled, warmed the earth because of the GHGs created as the lava rose through coal beds.Ah. So frogs are in Antarctica and palm trees in Alaska because of volcanoes.
Except volcanic activity cools the earth, Einstein.

Cuz a paper sez soze!Depends. The massive Siberian Traps cooled the earth, then, when the aerosols settled, warmed the earth because of the GHGs created as the lava rose through coal beds.
Abstract
The end-Permian extinction decimated up to 95% of carbonate shell-bearing marine species and 80% of land animals. Isotopic excursions, dissolution of shallow marine carbonates, and the demise of carbonate shell-bearing organisms suggest global warming and ocean acidification. The temporal association of the extinction with the Siberia flood basalts at approximately 250 Ma is well known, and recent evidence suggests these flood basalts may have mobilized carbon in thick deposits of organic-rich sediments. Large isotopic excursions recorded in this period are potentially explained by rapid venting of coal-derived methane, which has primarily been attributed to metamorphism of coal by basaltic intrusion. However, recently discovered contemporaneous deposits of fly ash in northern Canada suggest large-scale combustion of coal as an additional mechanism for rapid release of carbon. This massive coal combustion may have resulted from explosive interaction with basalt sills of the Siberian Traps. Here we present physical analysis of explosive eruption of coal and basalt, demonstrating that it is a viable mechanism for global extinction. We describe and constrain the physics of this process including necessary magnitudes of basaltic intrusion, mixing and mobilization of coal and basalt, ascent to the surface, explosive combustion, and the atmospheric rise necessary for global distribution.

Because evidence says so. Which, naturally, is a foreign concept to a challenged person like you.Cuz a paper sez soze!
No, you stupid ass, because they have evidence that indicates that was the case. And there are many other papers presenting evidence from other sources that back up this paper. In the meantime, you flap yap without presenting evidence of any kind for your ridiculous claims.Cuz a paper sez soze!
Frog Fossils Found in Antarctica
Nah, that's your excuse for knowing nothing about this and being happy to keep it that way. Yet, you want to be entitled to an opinion anyway. So you treat us to this embarrassing horseshit.When politics enters science, all bets are off.
