Earth may be near tipping point

[yeahwho]

I know that most people don't give a shit, deny, debate and generally get agitated and irritated if confronted with science, but here goes...

Another alarm to file away as you wish... false or real Earth may be near tipping point, scientists warn from the LATimes 6/7/2012

"The net effects of what we're causing could actually be equivalent to an asteroid striking the Earth in a worst-case scenario," the paper's lead author, Anthony Barnosky, a professor of integrative biology at UC Berkeley, said in an interview. "I don't want to sound like Armageddon. I think the point to be made is that if we just ignore all the warning signs of how we're changing the Earth, the scenario of losses of biodiversity — 75% or more — is not an outlandish scenario at all."

Global population just passed 7 billion and is expected to reach 9.3 billion or more by 2050. "By the year 2070, we'll live in a hotter world than it's been since humans evolved as a species," Barnosky said.
