I do too. Ive always loved paleontology and evolution especially since I first read Attenborough's book "Life on Earth". I almost decided to go for a paleontology MS degree but got sidetracked. I love geology too so this Permian extinction is very interesting. I just hope we dont repeat it now! They say CO2 output is higher now than the Permian.

We had a huge lava floods here in the PNW (far smaller than the Siberian Traps) from 17-13 million years ago and formed much of the PNW. It was from volcanic faults in NE Oregon from a "hot spot" in the earth's crust that has migrated since across southern Idaho to Yellowstone now.

CO2 injection far higher now than Permian extinction. ErikJ Jan 2013 #16

Why didn't the Eocene Thermal Maximum lead to extinction then? caseymoz Jan 2013 #19

Still most popular theory ErikJ Jan 2013 #20

Yes, but that should have caused a runaway increase to 10 degrees. caseymoz Jan 2013 #21
