Thanks for posting this.
And the Sun wasn't as hot back then either,....from an earlier thread.

The extinction that killed the dinosaurs about 65 million years ago, that wasn't anything compared to this. A Larson classic:

If I remember correctly, it was a very dry spring as well.

And just how do they know this to be true? Was he there taking the temperature 247 million years ago? Oh, let me guess, in one of his past lives he was an ancient meteorologist. It could happen.

Not sure about the temp data, but the mass extinction can clearly be seen in the fossil record. The best fossil beds from this era are in the Karoo area of South Africa. 90% of the life in the world doesn't disappear without some pretty extreme conditions. So we know something very extreme happened.

It's something called "Science" and it involves spending upwards of 8-10 years in school, and then years of work in the field, by dozens and dozens of people.
You're not going to get a full explanation of how temperatures are estimated millions of years ago from a short AP wire service article. However, I doubt you'd read anything longer on the subject.

"Roth is a geologist by training and a former science teacher who has worked as a natural resource specialist at the monument for 17 years."
BUNK - Pure environmental babble-trash ... The MAIN explination that historical geologists give for the mass extention at the Permian/Triassic boundry is changing sea levels caused by GLACIATION and GLOBAL COOLING, not carbon dioxide.
"Although the cause of the Permian mass extinction remains a debate, numerous theories have been formulated to explain the events of the extinction. One of the most current theories for the mass extinction of the Permian is an agent that has been also held responsible for the Ordovician and Devonian crises, glaciation on Gondwana. A similar glaciation event in the Permian would likely produce mass extinction in the same manner as previous, that is, by a global widespread cooling and/or worldwide lowering of sea level."

You find some tropical plant fossils in the Dakotas, carbon date them to millions of years ago, and conclude it used to be hot.

jaguar fossil found in the caves in 1995 Well, 90's Jags did have an overheating problem, but it was usually a faulty water pump.

Actually it appears the site you cite, and a handful of others, are flat out wrong or confused.
Certainly the more recent cites and articles and the more fully explained articles, and by far the majority, attribute the Permian extinction to warming, not cooling.
I wonder if some sites are confusing the Permian extinction and the "Snowball Earth" hundreds of millions of years earlier.
To: pctech
Actually they guess-estmate the temperature by study of tree rings. Now go ahead and say there are no trees around.

Everything I have seen recently points to an earth-impact in what is now Australia. Based on the volume and distribution of the shocked quartz, it may be larger than the Yucatan collision.

Hardly confused.
Scientists are always debating about the evidence they find. For example, while the asteroid impact theory about the demise of dinosaurs is the one favored today, there are still well trained experts in the field who disagree.
Another big area of disagreement is the origin of birds. While all paleontologists agree that they are descended from archeosaurs, some feel they are really dinosaurs, while others feel they come from a closely related but distinctly separate line of reptiles.
Even with all the research and new discoveries and new ways of interpreting data, we might never know for sure.
