Our World and Everything in It

Did you know that a lake could blow up from CO2 gases settled on the bottom? Until 1986 scientists didn’t think so either. I was watching the History Channel. A Professor Riskin hypothesized about methane gas sea explosions causing prehistoric earth to scorch. The scientific community was not convinced about gas exploding out of the ocean until in 1986 Lake Nios in Cameroon, Africa exploded from 1.6 million tons of CO2 gas being released that had settled on the bottom. Over 1700 people were asphyxiated up to 16 miles away along with all their livestock, some 3000 head of cattle.
 
Scientists argued for a while that it was a volcanic eruption and a mix of sulfur that caused the explosion, but sulfur substances weren’t found. The survivors of the explosion claimed they smelled sulfur but there is evidently something called olfactory hallucinations associated with CO2 asphyxiation and one of them is the smell of sulfur.

According to an article on Bnet, it was believed carbon dioxide gas build-up had a volcanic origin and built up slowly in the lake over a long period of time. U.S. researchers didn’t know exactly what triggered the explosion, but it was never believed a volcano or earthquake was responsible. French researchers disagreed. They believed the exploding cloud that dispersed throughout the area traveling at 40 mph was a mix “of steam, carbon dioxide and sulfur compounds that had been building up in a layer of groundwater heated by volcanic rocks far below the lake. These compounds reportedly were injected into the lake when the pressure of the steam eventually cracked the rock that had been holding it down.”

The problem is “U.S.scientists said lake temperatures were not elevated, its bottom did not appear to have been disturbed, there were no volcanic sulfides in the lake and no suspended sediments that might have resulted had steam rushed through bottom sediments.”

Either way we look at it, whether the CO2 was just laying there and blew or was caused by too much pressure from too much CO2 being injected into the rock fissures, it does not bode well for a future with too much CO2 around. So much for the gasification process relative to “clean coal.”

Coal burns filthy. The reason why it’s recently being touted as “clean” is because of a gasification process where the CO2 pollution is trapped, and liquified. The pollution never gets into the air but the liquified CO2 needs some place to go. Just like the spent fuel of a nuke, the best place for the leftover liquid CO2 is to put it in the ground by injection. But do we know how much CO2 is safe to inject? Will we have to worry about CO2 geisers in the future?  If so the future is looking pretty prehistoric. Told ya we’re dinosaurs.
