Ok last year I posted that rates of atmospheric C02 rises had jumped of the scale for the first time in recorded history- a 3.22ppm rise recorded at Mauna Loa.
A few months back, the second seal was opened. The annual "upwelling" off the coast of greenland arrived 2 months later than usual, for the first time in recorded history.
And now, as I predicted...the atlantic conveyor is shutting down...if it does so completely, were talking plungeing temparatures and a new ice age across much of the Northern hemisphere. The resulting chaos will not be pretty.
But its all our own fault.
Key warming ocean current slowing down: scientists
By Jeremy Lovell
Wed Nov 30, 1:04 PM ET
LONDON (Reuters) - The Atlantic Conveyor, a life-giving ocean current that keeps northern Europe warm, is slowing down, scientists said on Wednesday.
If the 30 percent slowdown seen over the past 12 years is not just a blip, temperatures in northern Europe could drop significantly, despite global warming, they added.

Indeed, Europe in particular is said to be in for the roughest bout of weather & natural catastrophes it has faced in some 5,000 years 
Whew!!! Guess we're all so lucky to be living in Asia ... eh? |

I wouldn't call it natural. Yes the conveyor current has shut down previously, prompting mini ice ages, many millenia ago..but that was caused by natural processes. This time man-made global warming is to blame. The sheer rapidity of polar ice cap melting due to the removal of protective ozone and the warming of atmosphere due to human emissions of greenhouse gasses is unprecedented.
The volume of frigid meltwater pouring into the area around greenland disrupts the natural warm-cold circulation of ocean water that dispenses warm winds and nutrients around the continents. It has not only raised ocean levels significantly this century but also changed weather patterns worldwide.
We're edging closer:) |

now now troll this threads for the big boys ok? but if you're genuinely curious, read the post i just made, should give you some clues.
While you're smoking crack, put this in the pipe..BANg another report by a team of scientists to unsettle even the most hard-bitten global warming denier:
Oceans, greenhouse gases rising faster: reports By Susan Heavey
Thu Nov 24, 2:04 PM ET
WASHINGTON (Reuters) - Ocean and so-called greenhouse gas levels are rising faster than they have for thousands of years, according to two reports published on Thursday that are likely to fuel debate on global warming.
One study found the Earth's ocean levels have risen twice as fast in the past 150 years, signaling the impact of human activity on temperatures worldwide, researchers said in the journal Science.
Sea levels were rising by about 1 millimeter (0.04 inches) every year about 200 years ago and as far back as 5,000 years, geologists found from deep sediment samples from the New Jersey coastline. Since then, levels have risen by about 2 millimeters (0.08 inches) a year.
While the planet has been in a warmer period, driving cars and other activities that create carbon dioxide are having a clear impact, the Rutgers University-led team said.

Oh yeah!! Time to start building a new home to live on Mars i guess. |

A natural phenomenon then, 'impacted' by human activity.

European researchers using three large samples of polar cap ice found carbon dioxide levels were stable until 200 years ago.
"Today's rise is about 200 times faster than any rise recorded" in the samples, study author Thomas Stocker said in an e-mail interview with Reuters. |
To get a bigger picture..lets look at the history of glaciation. Changes in sea level have a marked effect in climate:

Either way..what we're talking about is the shutting down and disruption of ocean currents. Its happened before, (although i will have to research this one) i believe it was caused by meteorite impact and the resulting cooling caused by so much dust in the atmosphere obscuring the sun. |

Ya-ya, off the thread. If you've got nothing to do but disparage other's posts, why bother?
For Chrissake, you take the obvious - a relationship between man's impact and the natural world - and act as if you've got a fricking POINT?? What IDIOT would even begin to believe the two are not interracting? What scientist worth the price of his first lunch in grade school would try to claim global warming didn't have a natural element??
Jesus, what a waste. STFUA. |
