ASPEN — Some scientists say the Earth is headed for “a very large extinction spasm” if current trends continue, moderator Michael Totten told a panel of experts at the Aspen Environment Forum on Saturday.
That prediction, he said, is based on estimates of how much carbon dioxide and other greenhouse gases will be pumped into the atmosphere in the coming decades, and the level at which the scientists believe the animal and plant life on Earth will begin to die off in massive numbers.
