The same noxious compounds released from burning coal and crude oil may have devastated forests and the early dinosaurs that lived in them 200 million years ago.
Scientists have known for decades of a massive dying between the Triassic and Jurassic eras. Life around the world was pummeled by runaway global warming, and scientists speculate that huge volcanic eruptions are responsible, belching vast amounts of carbon dioxide (CO2) into the atmosphere.
But a new study suggests polycyclic aromatic hydrocarbons (PAHs) and sulphur dioxide (SO2), two highly toxic pollutants common in fossil fuels, were released in huge quantities and played a role in snuffing out the lush forests of the northern hemisphere along with many species of early dinosaurs.

Last gasp ping.
You see there was this ancient dynasty of cave men (we are going to call them the Bushes)... and they wanted to destroy all the good animals...
I don't think SO2 is present in fossil fuels. S maybe.
I dropped my subscription to Popular Science because of their support for glo-bull warming. When they called to ask why I didn’t renew, I told them that they ought to rename their magazine to “Junk Science” if they were going to push glo-bull warming.
What a load. Volcanic eruptions are associated with cooling events. And before the global warming hysteria, geologists always considered the warming periods as ideal and optimum.
Sulfur Dioxide is present in fossil fuels. When mixed with water, it forms sulfuric acid. Spotted al gore tried to blame the tree die-off at the top of Clingman’s Dome (the highest spot in Tennessee) to this. The REAL culprit was an infestation of some insect. Completely natural.
...or maybe (JUST MAYBE) these are naturally-occurring gases due to volcanism and dinosaur flatus.
In a natural forest, fires periodically clear out old trees. By putting out fires, and allowing trees to get very old, it's easier for infestations like that to take hold.
Global warming my a-.Scientists Find Signs of Meteor Crash That Led to Extinctions in Era Before DinosaursDr. Becker, Dr. Poreda and their colleagues had previously found buckyballs at an impact crater in Sudbury, Canada, and in two meteorites. They have also found buckyballs containing similar types of gases in sediments dating from the dinosaur extinctions.

In the experiments, the scientists extracted buckyballs -- not just the typical sphere consisting of 60 carbon atoms, but also larger versions with up to 160 atoms -- from the sediments with organic solvents.
They then opened the buckyballs to release the helium and argon inside them. The nuclei of most helium atoms consist of two protons and two neutrons. A few -- one out of 700,000 helium atoms in the atmosphere -- are a lighter version, with only one neutron. For the helium in the buckyballs, a much larger fraction -- one out of 5,000 -- was the lighter version, similar to the ratio produced by fusion in stars.
The argon indicated a similar story, with low concentrations of a version that is commonly produced on Earth from the radioactive decay of potassium.
"I think the argon isotope ratio measurement is very convincing," said Dr. Kenneth A. Farley, a professor of geochemistry at the California Institute of Technology. "That's very hard to understand if it's not extraterrestrial."

New Extinction Clues Point to Deep ImpactNew evidence shows that an extinction event in which more than half of all Earth species died 200 million years ago happened quickly, possibly as a result of an impact from outer space. The extinction, at the boundary of the Triassic and Jurassic periods of geologic history, is similar in its suddenness to two extinction events that have been linked to space rocks' impacts on the Earth. Researchers analyzing deposits from a rock formation on a remote beach front in Canada found evidence of a sharp shift in organic carbon levels at precisely the point in time that the Triassic-Jurassic extinction occurred. This is the first time scientists have found a clear carbon signature for what is called the TJ event, said Peter D. Ward, a researcher at the University of Washington... Similar evidence has been found for the Cretaceous-Tertiary extinction event 65 million years ago that killed off the dinosaurs, and for the much earlier Permian extinction 250 million years ago that killed 90 percent of all species... If the researchers find evidence that a space rock impact caused the TJ extinction, it will mean that three of the five major extinctions in the 4.5-billion-year history of the Earth are linked to the impact of asteroids or comets... Ward said that no impact crater on Earth has been shown to have a proven link to the TJ extinction event, although the Manicougan Crater in Quebec is considered a candidate. That crater was caused by a space impact, but it has been dated at 214 million years, well before the TJ event.

It was all them ‘effin’ caveman SUV’s
Yeah, like a world-wide FLODD. Water in MASS is kinda toxic.
Just hopeless...
Is that one of them nekkid things?
OOPPS Flood :-)!
