Come on mate, despite what you say, you know as well as anyone that skewed and false data has been presented for years to further the AGW agenda.

It soon came to light that the data produced by NASA to make the claim, and in particular temperature records covering large areas of Russia, was merely carried over from the previous month.

in the Arctic, despite satellite imagery clearly showing that Arctic sea ice had massively expanded its coverage by 30 per cent, an area the size of Germany, since summer 2007.

Usually the Arctic icecap recedes in summer and then grows back in winter. These findings suggest the period in which the ice renews itself has become much shorter.
Dr Katharine Giles, who led the study and is based at the Centre for Polar Observation and Modelling at University College London (UCL), said the thickness of Arctic sea ice had shown a slow downward trend during the previous five winters but then accelerated.
She said: “After the summer 2007 record melting, the thickness of the winter ice also nose-dived. What is concerning is that sea ice is not just receding but it is also thinning.”
The research, reported in Geophysical Research Letters, showed that last winter the average thickness of sea ice over the whole Arctic was 26cm (10%) less than the average thickness of the previous five winters.
However, sea ice in the western Arctic lost about 49cm of thickness. This region saw the Northwest Passage become ice-free and open to shipping for the first time in 30 years during the summer of 2007.
You are right. GW is real and trying to attack it or obscure the reality of it by attacking one or two sources in amongst the many, many, many that concur, will not change this. I am glad we agree.

Obfuscating and attacking the source isn't going to change that one little bit.
BTW since we are sourcing UK tabloids, i won't post any science, as I know the Redneck is wary of those pesky "maker upers fiction people". I wonder if Prison Planet ever makes stuff up?

For what its worth Fox News is reporting this story.
I imagine the other news networks are probably reporting it also.

statistics can go this way or that way depending on which side of the coin is paying for them but the fact of the matter is if you want evidence of global warming just look at the enviroments around us coral bleeching rise in ocean tempreatures, increase in marine jelly balls (sounds funny but google it)

The Institute's Doctor Ray Berkelmans found signs of elevated sea temperatures in the tropics which threaten to bleach the reef's coral.
RAY BERKELMANS: There's some signs of unusually warm water building there. The winds are not going the right way … they're pushing sort of westerly instead of the normal easterly trade winds that we would normally get.
So those signs are a little bit worrying.
ANDREW GEOGHEGAN: Just explain to us what effect coral bleaching has on the reef.
RAY BERKELMANS: Well coral bleaching is a warm water stress event, generally speaking. It basically signals the breakdown in symbiosis between the coral and the algae that it needs to survive on. They get most of their food from the algae. And when that breakdown happens in the symbiosis, the coral has basically lost its food source, and if the stress is long enough or severe enough the coral can die.
ANDREW GEOGHEGAN: Recent research found that up to one fifth of world's coral reefs have been destroyed, while more than two thirds are in danger of dying.
Rising ocean temperatures in key hurricane breeding grounds of the Atlantic and Pacific oceans are due primarily to human-caused increases in greenhouse gas concentrations, according to a study published online in the September 11 issue of the Proceedings of the National Academy of Sciences (PNAS).
Using 22 different computer models of the climate system, Benjamin Santer and six other atmospheric scientists from the Lawrence Livermore National Laboratory, together with Tom Wigley, Gerald Meehl, and Warren Washington from the Boulder-based National Center for Atmospheric Research (NCAR) and scientists from eight other research centers, have shown that the warming sea surface temperatures (SSTs) of the tropical Atlantic and Pacific oceans over the last century are linked to human activities.
The brightly-coloured corals that make Australia's Great Barrier Reef one of the world's natural wonders will be largely dead by 2050 because of rising sea temperatures.
Instead of the rich environment depicted in the recent movie Finding Nemo, the coral reef will be bleached out and replaced by ordinary seaweed, costing the tourism industry billion of dollars, the report into the impact of global warming says.
Authors Hans and Ove Hoegh-Guldberg — the head of Queensland University's marine studies centre and his economist father — spent two years examining the effects of rising sea temperature on the reef for Queensland tourism authorities and the World Wildlife Fund for Nature.
Their 350-page report found no prospect of avoiding the "chilling long-term eventualities" of coral bleaching because greenhouse gases were already warming the seas as part of a process that would take decades to stop.
"Coral cover will decrease to less than five percent on most reefs by the middle of the century under even the most favourable assumptions," the report said. "This is the only plausible conclusion if sea temperatures continue to rise."
Warmer sea waters make corals suffer thermal stress, eventually making them bleach and die.
n important piece of the global-warming picture has come into clearer focus with a confirmation by scientists that the world's oceans have soaked up much of the warming of the last four decades, delaying its full effect on the atmosphere and thus on climate.
The warming of the deep oceans had long been predicted, and the consequent delaying effect long thought to exist.
But until now the ocean's heat absorption had not been definitively demonstrated, and its magnitude had not been determined.
The finding, by scientists at the National Oceanographic Data Center in Silver Spring, Md., is based on an analysis of 5.1 million measurements, by instruments around the world, of the top two miles of ocean waters from the mid-1950's to the mid-1990's.
The analysis, the first on a global scale, is being published today in the journal Science.
Coral bleaching is a vivid sign of corals responding to stress which can be induced by any of:
increased or reduced water temperatures (often attributed to global warming)
increased solar irradiance (photosynthetically active radiation and ultraviolet band light)
changes in water chemistry (in particular ocean acidification)
starvation caused by a decline in zooplankton levels as a result of overfishing.
increased sedimentation (can be contributed to silt runoff)
pathogen infections
changes in salinity
