"Correlates"
Think about that. It's not true, anyhow, but citing correlation as proof is cute in a middle school kind of way, although I may be insulting middle-schoolers.

The Para wodna is clearly falsified, you can tell that by looking at the Metan and the Tlenki azotu.

Looks like the Obama voters taken over the thread.
It seems like you make a lot of the issues discussed here divided between who posters voted for during the presidential election. This is about global warming, not who posters voted for during the election.

"this was the moment when the rise of the oceans began to slow and our planet began to heal ..."

So for you, this link shows that: if you believe global warming is increasing because of mankind, you voted for Obama.
Arctic summers ice-free 'by 2013'
By Jonathan Amos
Science reporter, BBC News, San Francisco
Arctic summer melting in 2007 set new records
Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.
Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.
Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.
Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.
Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections.
In the end, it will just melt away quite suddenly
"Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007," the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC.
"So given that fact, you can argue that may be our projection of 2013 is already too conservative."
Using supercomputers to crunch through possible future outcomes has become a standard part of climate science in recent years.
Professor Maslowski's group, which includes co-workers at Nasa and the Institute of Oceanology, Polish Academy of Sciences (PAS), is well known for producing modelled dates that are in advance of other teams.
These other teams have variously produced dates for an open summer ocean that, broadly speaking, go out from about 2040 to 2100.
But the Monterey researcher believes these models have seriously underestimated some key melting processes. In particular, Professor Maslowski is adamant that models need to incorporate more realistic representations of the way warm water is moving into the Arctic basin from the Pacific and Atlantic oceans.
"My claim is that the global climate models underestimate the amount of heat delivered to the sea ice by oceanic advection," Professor Maslowski said.
"The reason is that their low spatial resolution actually limits them from seeing important detailed factors.
"We use a high-resolution regional model for the Arctic Ocean and sea ice forced with realistic atmospheric data. This way, we get much more realistic forcing, from above by the atmosphere and from the bottom by the ocean."
The Intergovernmental Panel on Climate Change (IPCC), the UN-led body which assesses the state of the Earth's climate system, uses an averaged group of models to forecast ice loss in the Arctic.
But it is has become apparent in recent years that the real, observed rate of summer ice melting is now starting to run well ahead of the models.
The minimum ice extent reached in September 2007 shattered the previous record for ice withdrawal set in 2005, of 5.32 million square km.
The long-term average minimum, based on data from 1979 to 2000, is 6.74 million square km. In comparison, 2007 was lower by 2.61 million square km, an area approximately equal to the size of Alaska and Texas combined, or the size of 10 United Kingdoms.
Diminishing returns
Professor Peter Wadhams from Cambridge University, UK, is an expert on Arctic ice. He has used sonar data collected by Royal Navy submarines to show that the volume loss is outstripping even area withdrawal, which is in agreement with the model result of Professor Maslowski.
"Some models have not been taking proper account of the physical processes that go on," he commented.
"The ice is thinning faster than it is shrinking; and some modellers have been assuming the ice was a rather thick slab.
"Wieslaw's model is more efficient because it works with data and it takes account of processes that happen internally in the ice."
Arctic sea ice extent for May averaged 12.78 million square kilometers (4.93 million square miles). This is 610,000 square kilometers (235,500 square miles) below the 1981 to 2010 average for the month. May 2014 is now the third lowest May extent in the satellite record.
I only looked at your link for 30 seconds, so maybe I missed something, but it seems to say the opposite of what you claim.
How does 'third lowest May' translate to 'record high'?

Did you read the 2007 doomsday article I posted?
Probably not, since it blows your silly theories about accurate modeling to bits.
For example, if we were to plot the times PapaG shit his pants we'd find a very strong correlation to posts made about trading LaMarcus. You could analyze other potential causes and find little to no correlation. The causual link becomes even more apparant if you understand the mechanism by which it operates. In the case of global warming, we've known that Co2 is a greenhouse gas for a long time. That's how climate scientists are able to make the educated assertion than human produced Co2 is largely behind the increase in temperature. And I think they understand their craft a lot better than PapaG.

Who said anything about Jean Claude Van Damme?Man can dam a river but only god can damn a planet.

This article suggests the possibility that the sea is currently at the apex level for this cycle.
Could it be that the prediction discrepancy between .6' and 6' is slightly high, and between 0' feet and 6' is closer to the mark?
Perhaps 99% of the scientist could agree with corrected prediction.
Where I live, the sea rises every day. Then lowers every day.
