Key facts about global temperature
Ø The RSS satellite dataset shows no global warming at all for 217 months from September 1996 to September 2014. That is more than half the 429-month satellite record.
Ø The global warming trend since 1900 is equivalent to 0.8 Cº per century. This is well within natural variability and may not have much to do with us.
Ø The fastest measured warming trend lasting ten years or more occurred over the 40 years from 1694-1733 in Central England. It was equivalent to 4.3 Cº per century.
Ø Since 1950, when a human influence on global temperature first became theoretically possible, the global warming trend has been equivalent to below 1.2 Cº per century.
Ø The fastest warming rate lasting ten years or more since 1950 occurred over the 33 years from 1974 to 2006. It was equivalent to 2.0 Cº per century.
Ø In 1990, the IPCC’s mid-range prediction of near-term warming was equivalent to 2.8 Cº per century, higher by two-thirds than its current prediction of 1.7 Cº/century.
Ø The global warming trend since 1990, when the IPCC wrote its first report, is equivalent to below 1.4 Cº per century – half of what the IPCC had then predicted.
Ø Though the IPCC has cut its near-term warming prediction, it has not cut its high-end business as usual centennial warming prediction of 4.8 Cº warming to 2100.
Ø The IPCC’s predicted 4.8 Cº warming by 2100 is well over twice the greatest rate of warming lasting more than ten years that has been measured since 1950.
Ø The IPCC’s 4.8 Cº-by-2100 prediction is almost four times the observed real-world warming trend since we might in theory have begun influencing it in 1950.
Ø From August 2001 to August 2014, the warming trend on the mean of the 5 global-temperature datasets is nil. No warming for 13 years 1 month.
Ø Recent extreme weather cannot be blamed on global warming, because there has not been any global warming. It is as simple as that.
Technical note
Our latest topical graph shows the RSS dataset for the 217 months September 1996 to September 2014 – just over half the 429-month satellite record. This is as far back as it is possible to go in the global instrumental record and find a zero trend. The start-date is not “cherry-picked” so as to coincide with the temperature spike caused by the 1998 el Niño: it is calculated so as to find the longest period with a zero trend.
Furthermore, the length of the pause in global warming, combined with the offsetting effect of the 2010 el Niño on the calculation, ensures that the distortion of the trend caused by the proximity of the 1998 el Niño to the 1996 start date for the trend is barely discernible.

blahahahahahahahhahahhaha
CO2 is still a greenhouse gas and rising levels of it has caused the unnatural warming we have seen. This chart clearly shows this. Only an irrational or very stupid or depraved ideologue like jem and piehole would deny this.
No matter how many times you post this chart it still only shows that the oceans have absorbed the heat and this is natural variability and the models do not or are expected to include these short term effects.
Also, once again you are posting crap from unreliable and agenda driven propaganda websites. Why oh why can't you use authoritative sources like NOAA and NASA?
Is it because you a depraved ideological troll? Of course it is.
WUWT is NOT an authoritative reliable source of science. That's why they call it LOLWUWT

there is no consensus.
http://www.forbes.com/sites/larrybell/2012/07/17/that-scientific-global-warming-consensus-not/
While real polling of climate scientists and organization memberships is rare, there are a few examples. A 2008 international survey of climate scientists conducted by German scientists Dennis Bray and Hans von Storch revealed deep disagreement regarding two-thirds of the 54 questions asked about their professional views. Responses to about half of those areas were skewed on the “skeptic” side, with no consensus to support any alarm. The majority did not believe that atmospheric models can deal with important influences of clouds, precipitation, atmospheric convection, ocean convection, or turbulence. Most also did not believe that climate models can predict precipitation, sea level rise, extreme weather events, or temperature values for the next 50 years.
A 2010 survey of media broadcast meteorologists conducted by the George Mason University Center for Climate Change Communication found that 63% of 571 who responded believe global warming is mostly caused by natural, not human, causes. Those polled included members of the American Meteorological Society (AMS) and the National Weather Association.
A more recent 2012 survey published by the AMS found that only one in four respondents agreed with UN Intergovernmental Panel on Climate Change claims that humans are primarily responsible for recent warming. And while 89% believe that global warming is occurring, only 30% said they were very worried.
A March 2008 canvas of 51,000 Canadian scientists with the Association of Professional Engineers, Geologists and Geophysics of Alberta (APEGGA) found that although 99% of 1,077 replies believe climate is changing, 68% disagreed with the statement that “…the debate on the scientific causes of recent climate change is settled.” Only 26% of them attributed global warming to “human activity like burning fossil fuels.” Regarding these results, APEGGA’s executive director, Neil Windsor, commented, “We’re not surprised at all. There is no clear consensus of scientists that we know of.”
A 2009 report issued by the Polish Academy of Sciences PAN Committee of Geological Sciences, a major scientific institution in the European Union, agrees that the purported climate consensus argument is becoming increasingly untenable. It says, in part, that: “Over the past 400 thousand years – even without human intervention – the level of CO2 in the air, based on the Antarctic ice cores, has already been similar four times, and even higher than the current value. At the end of the last ice age, within a time [interval] of a few hundred years, the average annual temperature changed over the globe several times. In total, it has gone up by almost 10 °C in the northern hemisphere, [and] therefore the changes mentioned above were incomparably more dramatic than the changes reported today.”
The report concludes: “The PAN Committee of Geological Sciences believes it necessary to start an interdisciplinary research based on comprehensive monitoring and modeling of the impact of other factors – not just the level of CO2 – on the climate. Only this kind of approach will bring us closer to identifying the causes of climate change.”
Finally, although any 98% climate consensus is 100% baloney, this is something all reasonable scientists should really agree about.

A recent article by Larry Bell in Forbes went over the now-familiar ground of denying the consensus on climate change. He criticized the Doran and Zimmerman study for having too small a sample size and for asking vague questions (although, as I will discuss below, he is forgiving of similar questions and sample sizes of a study done by the Association of Professional Engineers, Geologists and Geophysicists of Alberta (APEGGA)). He cited the Oregon Petition, debunked here, while ignoring the work of Oreskes (2004) and Anderegg et al (2010). He cited the Polish Academy of Sciences PAN Committee of Geological Sciences, while ignoring the position of the General Assembly of the Polish Academy of Sciences, which endorses the IPCC conclusions, along with many other national science academies.
Most of Bell’s arguments have been debunked before and there’s little point in discussing them here again in detail. However, I have some personal familiarity with APEGGA, having been a member of this organization for many years, so I will look at that case of a supposedly dissenting scientific organisation in more detail. more . . .
http://wattsupwiththat.com/2009/01/...ys-hansen-embarrassed-nasa-was-never-muzzled/
Washington DC, Jan 27th 2009: NASA warming scientist James Hansen, one of former Vice-President Al Gore’s closest allies in the promotion of man-made global warming fears, is being publicly rebuked by his former supervisor at NASA.
Retired senior NASA atmospheric scientist, Dr. John S. Theon, the former supervisor of James Hansen, NASA’s vocal man-made global warming fear soothsayer, has now publicly declared himself a skeptic and declared that Hansen “embarrassed NASA” with his alarming climate claims and said Hansen was “was never muzzled.” Theon joins the rapidly growing ranks of international scientists abandoning the promotion of man-made global warming fears.
“I appreciate the opportunity to add my name to those who disagree that global warming is man made,” Theon wrote to the Minority Office at the Environment and Public Works Committee on January 15, 2009. “I was, in effect, Hansen’s supervisor because I had to justify his funding, allocate his resources, and evaluate his results,” Theon, the former Chief of the Climate Processes Research Program at NASA Headquarters and former Chief of the Atmospheric Dynamics & Radiation Branch explained.
“Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress,” Theon wrote. [Note: NASA scientist James Hansen has created worldwide media frenzy with his dire climate warning, his call for trials against those who dissent against man-made global warming fear, and his claims that he was allegedly muzzled by the Bush administration despite doing 1,400 on-the-job media interviews!- See: Don't Panic Over Predictions of Climate Doom - Get the Facts on James Hansen - UK Register: Veteran climate scientist says 'lock up the oil men' - June 23, 2008 & UK Guardian: NASA scientist calls for putting oil firm chiefs on trial for 'high crimes against humanity' for spreading doubt about man-made global warming - June 23, 2008 ]
Theon declared “climate models are useless.” “My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit,” Theon explained. “Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it. They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy,” he added.
“As Chief of several of NASA Headquarters’ programs (1982-94), an SES position, I was responsible for all weather and climate research in the entire agency, including the research work by James Hansen, Roy Spencer, Joanne Simpson, and several hundred other scientists at NASA field centers, in academia, and in the private sector who worked on climate research,” Theon wrote of his career. “This required a thorough understanding of the state of the science. I have kept up with climate science since retiring by reading books and journal articles,” Theon added. (LINK) Theon also co-authored the book “Advances in Remote Sensing Retrieval Methods.” [Note: Theon joins many current and former NASA scientists in dissenting from man-made climate fears. A small sampling includes: Aerospace engineer and physicist Dr. Michael Griffin, the former top administrator of NASA, Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a PhD in meteorology, and formerly of NASA, Geophysicist Dr. Phil Chapman, an astronautical engineer and former NASA astronaut,Award-Winning NASA Astronaut/Geologist and Moonwalker Jack Schmitt, Award-winning NASA Astronaut and Physicist Walter Cunningham of NASA's Apollo 7, Chemist and Nuclear Engineer Robert DeFayette was formerly with NASA's Plum Brook Reactor, Hungarian Ferenc Miskolczi, an atmospheric physicist with 30 years of experience and a former researcher with NASA's Ames Research Center, Climatologist Dr. John Christy, Climatologist Dr. Roy W. Spencer, Atmospheric Scientist Ross Hays of NASA's Columbia Scientific Balloon Facility]
Gore faces a much different scientific climate in 2009 than the one he faced in 2006 when his film “An Inconvenient Truth” was released. According to satellite data, the Earth has cooled since Gore’s film was released, Antarctic sea ice extent has grown to record levels, sea level rise has slowed, ocean temperatures have failed to warm, and more and more scientists have publicly declared their dissent from man-made climate fears as peer-reviewed studies continue to man-made counter warming fears.[See: Peer-Reviewed Study challenges 'notion that human emissions are responsible for global warming' &New Peer-Reviewed Scientific Studies Chill Global Warming Fears ]
“Vice President Gore and the other promoters of man-made climate fears endless claims that the “debate is over” appear to be ignoring scientific reality,” Senator James Inhofe, Ranking Member of the Environment & Public Works Committee.
A U.S. Senate Minority Report released in December 2008 details over 650 international scientists who are dissenting from man-made global warming fears promoted by the UN and yourself. Many of the scientists profiled are former UN IPCC scientists and former believers in man-made climate change that have reversed their views in recent years. The report continues to grow almost daily. We have just received a request from an Italian scientist, and a Czech scientist to join the 650 dissenting scientists report. A chemist from the U.S. Naval Academy is about to be added, and more Japanese scientists are dissenting. Finally, many more meteorologists will be added and another former UN IPCC scientist is about to be included. These scientists are openly rebelling against the climate orthodoxy promoted by Gore and the UN IPCC.

Not even close to being debunked...
the nutter claim was debunked in a recent peer reviewed paper...
Only 41 out of the 11,944 published climate papers Cook examined explicitly stated that Man caused most of the warming since 1950. Cook himself had flagged just 64 papers as explicitly supporting that consensus, but 23 of the 64 had not in fact supported it.

0.3% climate consensus, not 97.1%
PRESS RELEASE â September 3rd, 2013
A major peer-reviewed paper by four senior researchers has exposed grave errors in an earlier paper in a new and unknown journal that had claimed a 97.1% scientific consensus that Man had caused at least half the 0.7 Cº global warming since 1950.
A tweet in President Obamaâs name had assumed that the earlier, flawed paper, by John Cook and others, showed 97% endorsement of the notion that climate change is dangerous:
âNinety-seven percent of scientists agree: #climate change is real, man-made and dangerous.â [Emphasis added]
The new paper by the leading climatologist Dr David Legates and his colleagues, published in the respected Science and Education journal, now in its 21st year of publication, reveals that Cook had not considered whether scientists and their published papers had said climate change was âdangerousâ.
The consensus Cook considered was the standard definition: that Man had caused most post-1950 warming. Even on this weaker definition the true consensus among published scientific papers is now demonstrated to be not 97.1%, as Cook had claimed, but only 0.3%.
Only 41 out of the 11,944 published climate papers Cook examined explicitly stated that Man caused most of the warming since 1950. Cook himself had flagged just 64 papers as explicitly supporting that consensus, but 23 of the 64 had not in fact supported it.
