Latest Holocene extinction Stories
An international team of scientists have discovered that climate change played a major role in causing mass extinction of mammals in the late quaternary era, 50,000 years ago.
If Earth is headed for a mass extinction like the previous five, in which more than 75 percent of all species were wiped out, then North American mammals are one-fifth to one-half the way there.
Mammals may be nearly half way toward mass extinction.
U.S. scientists say the Earth is in the midst of its sixth mass extinction of plants and animals, with nearly 50 percent of all species disappearing. Biologists at the University of California-Santa Barbara say they are working to determine which species must be saved.
By the most conservative measure - based on the last century's recorded extinctions - the current rate of extinction is 100 times the background rate. But many scientists estimate that the true rate is more like 1,000 to 10,000 times the background rate.
