AGC: Humans responsible for global cooling, prevented mammoth gas release
Extrapolating from data on cows and other modern-day ruminants, the scientists estimated the total methane output of pre-historic megafauna at nearly 10 trillion grams per year.10 million tons. Hype much? At the same time, ice-core samples reveal that an abrupt drop in atmospheric methane levels of 180 parts per billion by volume (ppbv) coincides with both the virtual extinction of these gas-gushing herbivores and the onset of the deep chill that followed. Clone those mammoths and release in Nebraska. Problem solved. Posted by: KBK 2010-05-23 |
