lambdo Posted February 4, 2009 Report Share Posted February 4, 2009 Interesting article - first scientific evidence of results of an ozone depleted enviroment Bonus for Cal, not all based on carbon emissions... Fascinating stuff, although we did know ozone layer has the ability to repair itself; to what degree is still an unknown. Pretty amazing that total destruction of the environment has happened before and that the consequences are not destruction of the earth..simply an extinction of all (or most) living things on it. Link to article Now a team of researchers led by Henrik Svenson of the University of Oslo in Norway have performed a series of experiments, showing the volcano employed an arsenal of deadly weapons during its 200,000-year-long assault on the biosphere. Prime among them was carbon. Searing magmas from the volcano intruded into the Tunguska Basin in eastern Siberia, a region laden with thick deposits of coal, oil and gas. Heat from the molten rock baked the hydrocarbons, turning the area into the world's largest fossil fuel-burning plant. In all, the volcano may have belched as much as 100,000 gigatons of carbon into the air (all of humanity emits about eight gigatons of carbon annually). That's more than enough to cause a global climate apocalypse. But the team also wanted to know what happened when lava infiltrated the area's abundant salt deposits. When heated in a laboratory to 275 degrees Centigrade (527 degrees Fahrenheit), the salts released a host of toxic gases, chief among them methyl chloride, an efficient ozone-killer. "This is the first geologically realistic evidence that ozone collapse during the end-Permian could have actually happened," Svenson said. Link to comment Share on other sites More sharing options...
Legacy Fan Posted February 4, 2009 Report Share Posted February 4, 2009 Yikes. Methyl chloride is an extremely easy compound to synthesize and is done so in nature by any (read: all) vegetation that participates in photosynthesis. Predominately released by plankton because it exists and photosynthesizes oxygen in a salt water (NaCl) environment. Luckily, it's super volatile and more than likely dissolves (or reacts) before reaching most ozone or the layer would have been wiped out long ago.

calfoxwc Posted February 5, 2009 Report Share Posted February 5, 2009 I saw documentary on the "Killer Lake" - given underground lake happenings, it had released killer gas into the air, and flat out killed anything or anybody nearby. They had no problem while they were there - but they proved that the release of poisonous gases had happened before. That's a big lake, and a lot of poisonous gas into the air. That, and the historical fact or theory? that a giant volcanic eruption killed dinasaur life... well, feel free to turn your home heat to 72 degrees and don't feel guilty...

Chicopee John Posted February 5, 2009 Report Share Posted February 5, 2009 I won't be able to sleep tonight, tomorrow night or the night after. Man-made Global Warming!!!!!!!!!!!!!! Oh no. I am really worked up about my carbon footprint. Link to comment Share on other sites More sharing options...
Mr. T Posted February 5, 2009 Report Share Posted February 5, 2009 Yes I am really going to be cocerned over man made global warming, when we have had snow down here at the beach twice within the past 2 weeks. its going to be 20 degrees tonight and the plumbers will be happy to have work tomorrow.
