| AGC: Humans responsible for global cooling, prevented mammoth gas release |
| 2010-05-23 |
| 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. |

| #1 It was not enough to trigger runaway global warming. But when all that gaseous output suddenly tapered off, it caused or at least contributed to a prolonged freeze known as the Younger Dryas cold event, they argue. Interesting. There are other explanations for the sudden cooling of the Younger Dryas, but this is plausible. After a couple of thousand years of Younger Dryas cooling, the climate suddenly warmed again, which may well have resulted from the rise of animal husbandry. |
