The Earth is reaching a "tipping point" in climate change that will lead to increasingly rapid and irreversible destruction of the global environment unless its forces are controlled by concerted international action, an international group of scientists warns.
Unchecked population growth, the disappearance of critical plant and animal species, the over-exploitation of energy resources, and the rapidly warming climate are all combining to bring mounting pressure on the Earth's environmental health, they say.
Scientists from five nations, led by UC Berkeley biologist Anthony Barnosky, report their analysis Thursday in the journal Nature.
They likened the potential impact of the forces to previous major changes - both gradual and abrupt - in the planet's history that triggered mass extinctions and expansions, and produced completely new worldwide environments.
The most recent of those was the sporadic end of the last ice age that began 14,000 years ago and shifted rapidly from warm to cold and then back to warm again over a few thousand years. That period saw the extinction of half the world's large animal life, and then the spread of an expanding human population to every continent on the planet.
Difficult to reverse
A similar "critical transition" is occurring now, Barnosky's scientists maintain, and they warn that once it starts, it will be "extremely difficult or even impossible for the system to return to its previous state."

It’s all about timing.. Rio+20 media propaganda filler
—snip—
2 years of research
Barnosky, who tracks longtime changes in the fossil record, and 22 other scientists spent two years in conferences and research to produce their review. It is timed for a U.N. conference on sustainable development - known as the Rio+20 Conference - that is scheduled for Rio de Janeiro from June 22 to 24. The conference will mark 20 years since the first “Earth Summit” at Rio, involving delegates from 172 governments, produced the first international conventions on climate change and biodiversity.
Tell it to someone who isn’t having 40 and 50 degree nights in June.
The fringe left is losing influence everywhere and their flop-sweat is obvious do those who can see.
The Rust Belt is gonna turn into the Bikini Line yet. Rio must be nice this time of the year, heck any time of the year.
I have found a good chocolate bar and a glass of merlot will solve most of the worlds problems til the next morning. Drink up, America!

As soon as these RAT bastard socialist eco-environmental idiots get rid of any motorized vehicle, shut off all the electricity, running water, natural gas or fuel to their house, double up or triple up the number of occupants of their house, THEN they can make their point that they are trying to save the planet. Until they put their actions where their forked tongues reside, they can just STFU.
The 2nd disqualifer of these RAT turds and their whole bogus study? UC Berkeley biologist Anthony Barnosky. I wouldn't trust this RAT turd, liberal, progessive, socialist, marxist, fascist, commie pig any further than I could throw his phat elitist ass!

Current economic conditions doom anything they’re trying to pull.
They can go to hell where it’s really warm.
One nice thing though. That early burst of hot weather back in February brought the mosquitoes out and the following cold killed them off.
The mild winter means we’re overrun with rabbits (its like australia out there) and bullfrogs up the ying yang.
Once again, Science is not a consensus.
Before 1903, the “consensus” was that heavier-than-air craft could not fly. That view was even solidly guaranteed by Britain’s greatest living scientist at the time, Lord Kelvin.
How’d THAT consensus work out??
Let’s deal with all the facts here, including the one that human civilization has thrived only during warm periods.
Tomorrow’s high temperature in Chico, CA is forecast to be 82 degrees. Normal is 87 degrees. The record high was 106 in 1973. Last year on 6/8 the high was 79 degrees. Something tells me that these globull warming chicken little’s are full of something which has a horrid smell.
Good deal.
Hopefully it kills democrat scientistics first.
The latest sunspot cycle is the weakest in 100 years. Sites report concern of significant cooling as possible...
Then maybe these fools would shut up about it.
We've had temps in the upper 30s and low 40s in the early morning hours and snow over Memorial Day Weekend.
That's right people -- believe it!
But this damage to Mother Earth's environment can be stopped by:
We know the Earth has been hotter in the past. We know concentrations of CO2 have been substantially higher in the past. Yet in those times of hotter heat and CO2ier CO2, the Earth’s equilibrium did not cascade irretrievably out of control. How do we know this? Because it isn’t out of control now. So if hotter hotness and higher CO2 did not trigger a point of no return in the past, today’s lower levels of each cannot.
