| Quote: | By Chris Mooney, Washington Post
On a warming Earth, seas inevitably rise, as ice on land melts and makes its way to the ocean. And not only that — the ocean itself swells, because warm water expands. We already know this is happening — according to NASA, seas are currently rising at a rate of 3.5 millimeters per year, which converts to about 1.4 inches per decade.
However, scientists have long expected that the story should be even worse than this. Predictions suggest that seas should not only rise, but that the rise should accelerate, meaning that the annual rate of rise should itself increase over time. That’s because the great ice sheets, Greenland and Antarctica, should lose more and more mass, and the heat in the ocean should also increase.
The problem, or even mystery, is that scientists haven’t seen an unambiguous acceleration of sea level rise in a data record that’s considered the best for observing the problem — the one that began with the TOPEX/Poseidon satellite, which launched in late 1992 and carried an instrument, called a radar altimeter, that gives a very precise measurement of sea level around the globe. (It has since been succeeded by other satellites providing similar measurements.)
This record actually shows a decrease in the rate of sea level rise from the first decade measured by satellites (1993 to 2002) to the second one (2003 to 2012). “We’ve been looking at the altimeter records and scratching our heads, and saying, ‘why aren’t we seeing an acceleration in the satellite record?’ We should be,” said John Fasullo, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado.
In a new study in the open-access journal Scientific Reports, however, Fasullo and two colleagues say they have now resolved this problem. It turns out, they say, that sea level rise was artificially masked in the satellite record by the fact that one year before the satellite launched, the Earth experienced a major cooling pulse.
The cause? The 1991 eruption of Mount Pinatubo in the Philippines, which filled the planet’s stratosphere with aerosols that reflected sunlight away from the Earth and actually led to a slight sea level fall in ensuing years as the ocean temporarily cooled.
“What we’ve shown is that sea level acceleration is real, and it continues to be going on, it’s ongoing, and we understand why you don’t see it in the short satellite record,” said Fasullo, who conducted the research along with scientists from the University of Colorado in Boulder and Old Dominion University.
The study was performed using a suite of 40 climate change models to determine how the Pinatubo eruption affected seas and the global distribution of water. The scientists estimate as a result that sea level not only fell between 5 and 7 millimeters due to a major ocean cooling event in the eruption’s wake, but then experienced a rebound, or bounce back, of the same magnitude once the influence of the eruption had passed. |
I await the science free explanation from the ethics free oil industry. |

| I was at the beach today and the water level looked the same as it was when I was a kid. |

Well that settles that. The laser eyes of Golden Dawn. Funniest posting all year by GD.  |

| How's that investigation of Exxon by the cabal of 17 Democrat AG's and Al Gore going? I'm sure such an august body must have uncovered some bombshells by now, confirming the serious allegations they so proudly and publicly made. Otherwise they would look like a bunch of ill-informed, vote-grubbing fools. |

Nope, the sun and jet stream did it....water will soon cool down. |

remember Enron the largest contributor to Bush. and how they did it. well they shredded every document they had and had their accounting firm to do the same.
the tobacco companies gave us the testimony that cigarette smoking was safe. while we know they knew it was not. only because a brave person ratted them out. yet thousands in the company knew.
No different than Nixon hundreds were involved in illegal activities and none blew the whistle on him, it took some people getting caught breaking into dem HDQS, even then no one ratted these criminals out. It took a single FBI agent to go behind the back of all the FBI agents and tell a reporter he was on the right track and not give up.
Al Gore has no power to do much.

A week with Matthew from an Outer Banks homeowner:
Monday - computer models predict Matt to run up the East Coast and go directly over the OBX.
Tuesday - better news. The models indicate the center will likely move offshore before reaching OBX
Wednesday - even better news. Matt will brush S.Carolina before curving offshore, heading back South and possible making landfall again in Florida.
Thursday - same. Mandatory evacuation of Ocracoke lifted. OBX tourism board gleefully proclaims "Come on Down. We're open for business!"
Friday - models show storm might move a little further North before moving offshore and curving South. Southernmost parts of NC might feel the fringe of the storm.
Saturday - storm hits the entire OBX with the 3rd highest wind gusts recorded in Matt's US adventure. Torrential rains. Extensive damage and flooding.
Sunday - high winds all day. Storm moves slowly offshore and continues North, not South
Monday - storm continues North East, not South
When asked why they were so completely off the mark, forecasters explained that their computer models can only gives a wide range of indications. Many are unreliable and frequently proven wrong. When further asked why they can be so sure about global warming they said "That's what our computer models tell us. It's settled science." |
