Waspie_Dwarf Posted March 22, 2013 #1 Share Posted March 22, 2013 Mega Volcanoes May Have Caused Mass Extinction Massive volcanic eruptions may have led to the extermination of half of Earth's species some 200 million years ago, a new study suggests.The release of gases from giant eruptions caused climate change that led to the End-Triassic Extinction, the widespread loss of land and sea species that made way for the rise of the dinosaurs, the research says. The new study, published today (March 21) in the journal Science, shows that a set of major eruptions spanning from what is now New Jersey to Morocco occurred very close to the time of the extinction.

Guest Posted March 22, 2013 #2 Share Posted March 22, 2013 (edited) Notice what was the actual causative agent of the mass extinction - massive releases of sulphates and CO2 causing cooling and warming of the climate. Theres a lesson there if people could but spot it. Br Cornelius Edited March 22, 2013 by Guest Link to comment Share on other sites More sharing options...
Little Fish Posted March 24, 2013 #3 Share Posted March 24, 2013 Notice what was the actual causative agent notice the speculative words "may have". "Theres a lesson there if people could but spot it." the lesson being, do not extrapolate speculation to fact, and learn the difference between the two. 1 Link to comment Share on other sites More sharing options...

Guest Posted March 24, 2013 #5 Share Posted March 24, 2013 Why not - we are releasing massively more CO2 into the atmosphere than all the volcanos which are currently active. Br Cornelius Link to comment Share on other sites More sharing options...

Br Cornelius i'm well aware of your argument, the figure you used in the past if i remember was one hundred times that of volcanic C02. Link to comment Share on other sites More sharing options...
Guest Posted March 25, 2013 #7 Share Posted March 25, 2013 i'm well aware of your argument, the figure you used in the past if i remember was one hundred times that of volcanic C02. The main difference is that we are releasing it in a sustained cumulative way - which is entirely different to the scenario described here.
