Warming nears point of no return, scientists say ( .. and then We'RE REallY ReallY DooMeD!!)
SFGate.com ^ | 6/7/12 | David Perlman

Posted on 06/07/2012 7:46:08 PM PDT by NormsRevenge

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.

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!

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.

Warming nears point of no return, scientists say ( .. and then We'RE REallY ReallY DooMeD!!)

I could think they are congenital morons, but they certainly know that there were many periods of time in earth history, some recent, when warming was greater than the modest increase ending in 1998, sometimes much, MUCH greater and there was no "point of no return," but a return to colder, sometimes much, MUCH colder climates. They also know that there were many periods in earth's history where CO2 levels were many times greater than they are now and there was no "point of no return," but an overall trend to lower and lower levels of atmospheric CO2 until we are where we are now in a period of unprecedented low levels of CO2. Since they know that both of these things are without dispute, and since they continue to promote something that is completely contradictory to natural history, then we know that they are deceptive, untrustworthy, unscientific, and deserving to be thrown out on their asses and then locked up in jail for fraud.

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.

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.

As though all those large animal species evolved to their then-current glacial period size over a measly 100,000 or so years since the previous (and increasingly warmer) past four interglacial periods. Those large land mammals got fried by radiation from a huge zeta-pinch aurora (see PDFs number 15, 18, 24, and 25 at link) about 12,000 or so years ago.

They say that like it's a bad thing (to quote about twenty different Freepers).

Besides, it just how EARTH works. Adapt or die. All the money in the world cannot change it.

Anybody who follows this stuff consistently can tell you we reach this “tipping point” every couple of months - and more frequently if there’s a “climate change” conference coming up.

For example, from a news story on the “United Nations Climate Change Science Compendium Report” (UNEP) right around the time of the Copenhagen conference: “The UNEP 2009 report indicates that climate tipping points, which will result in irreversible accelerating changes to the planetary ecosystem, have already been been reached and possibly surpassed.”

So apparently we’ve already been there, we are now three years into being doomed, and there’s not much point in losing a whole lot more sleep over it.

I mean, I would be more than interested to watch and learn....it might take me a while though...I am really dense.

I might even seek investors and create a new TV genre and call it a “Reality Show” which would chronicle their wisdom of example.

Any takers?

Duh, wasn’t the “Medieval Warm” a lot warmer than it is today?

BTW, if we are going to be cooler than the Medieval Warm when we reach our “Point of No Return,” then maybe we can follow them after they reached and then returned from their “Point of No Return?”

BTW, BTW, since CO2 was unknown then, who did the “Medieval Warmies” blame? Since human nature doesn’t handle REALITY very well, they just MUST have had something or someone to blame!

These morons! Try reading a friggin' geology/paleontology book! About 90% of life on earth has been wiped out several times over the past 350 million years, and that's not to mention what plant and animal species are "critically endangered" everytime the Yellowstone Caldera pops like a giant volcanic zit and covers half the Continental US in ash every 600,000 years or so, which has been going for what, the last 30 or 40 million years? I forget, but something like that.

The last time about half of Florida was underwater was what, 120,000 years ago? About 100,000 years later (that would be about 20,000 years ago), sea levels were so low that Forida was TWICE the size that it is now.

ANYBODY presuming to "save the planet" by protecting beaches and wetlands is a conceited, ignorant lulu. Regardless of what mankind does or doesn't do in the next ten centuries, sooner or later all those beaches are going to be well underwater -- AGAIN. When it comes to climate, we don't control the climate, it controls us.

Furthermore, we couldn't even recognize, let alone manipulate, a significant climate change trend in the context of "normal" weather shifts amortized over hundreds of millions of years, if it bit us on the ass.
