Study: Sixth Extinction Event Is Underway
garyisabusyguy writes: We've heard proposals in the past that a new extinction event is underway. However, a new study takes into consideration many other factors that may be tilting the data, and still comes to the inevitable conclusion that we have triggered a large die-off, and that we may become victims of it as well.
From the paper's abstract: "Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way."
The authors suggest that rapid work to avert the worst of the die-off is still possible. The question may really be whether we can get past paid trolls, FUD, and finger pointing in order to act wisely in a timely manner.

And between the pecuniary interests, the people who cannot imagine anything beyond 3 months, and the folks who actually want the world to end, via either religion outcome, or just wanting to see the world burn - I suspect we're going to drive the bus off that extinction cliff while singing happy days are here again.
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
Is this the same Paul Ehrlich who became famous for predicting that overpopulation would kill off humanity long before we would see the 21st Century? Of course environmentalists, in bestowing upon us their latest set of apocalyptic "predictions" would pick someone who has been spectacularly wrong so often in the past.
Considering that most of Earth is overrun by humans and that many species are in minority and located to small shrinking areas it's a cause for concern. Only species that benefits humans or live in areas inhospitable for humans have a better chance of survival.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
Served just fine nearing on 20 years, slowly pushed to extinction by the rise of soulless, repulsive Dice Holdings now known as DHI.
Over fishing, petrochemical spills/pollution, and indirectly raising the temperature...
