I am in no way in favor of dumping CO2 into the atmosphere nor am I in favor of pollution but I think we should do our best in understanding what is happening and what happened in the past. If I were to guess I would say that the mass extinction events in Earth's history were not just from an increase in atmospheric CO2 levels nor global warming but a combination of things.
Yes i would say if an entire continent turns into mordor CO2 would be just a small part of the problem.
I think it’s important to address the OP as to not add to any possible thread derailments. As for the tree guy, do you mean this comment by turboneon?
So why does my crappy op matters and not the opinion of the guy that want to save the trees?
I don’t see a problem with that statement.
Maybe there wouldn't be as much CO2 in the air if we stopped cutting down all the forests.
It would be nice if you people talk a little bit about the guy in Utah and not the dinosaurs/china/...

Except you should read a bit more on how CO2 makes the oceans acid and kill most of the aquatic life
Permian extinctionedit on 20-2-2014 by Indigent because: (no reason given)
Yes lets go back to dinosaurs conditions they did well, its not like they became extinct or anything
Despite knowing about biodiversity’s importance for a long time, human activity has been causing massive extinctions. As the Environment New Service, reported back in August 1999 (previous link): “the current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue [resulting in] a loss that would easily equal those of past extinctions.” (Emphasis added)
lets go to the levels of CO2 where a super volcano was active and generated mass extinctions like the Siberian Traps, the trees will be huge, or not what you say fellow ATS?
As well as getting hotter there is evidence that the climate also cooled. Sedimentological evidence for cooling comes from glacial deposits in polar zones, and thick dune sands and evaporites from temperate zones that represent a cool dry environment.
Some of the volcanic gasses released from the Siberian trap flood basalts could have the opposite affect to the CO2, cooling the climate insted of heating it. Why these had this affect is mentioned in volcanism
Other evidence comes form the reduced presence of carbonate limestones around the end of the Permian. This process would have had the greatest affect in the tropics where most of the Earth's limestone production occurs. Cooling would eliminate the tropical ares and kill tropical species, and if there were less Carbonate produceres there would be less Carbonate which is what is seen.
Another cooling affect comes from glaciation. Cooling can happen in low latitudes without there being glaciation and in this way just the cooling of the climate would be the cause of extinction by the method mentioned above.
The Utah lawmaker said, 'The dinosaurs did pretty well at 600ppm', That statement is nonsense. Your reply is nonsense.
