Debunking the myth of consensus on global warming.
No Consensus
"I can tolerate being called a skeptic because all scientists should be skeptics, but then they started calling us deniers, with all the connotations of the Holocaust. That is an obscenity. It has got really nasty and personal." - Timothy Ball, climatology professor emeritus at the University of Winnipeg in Canada

Seriously?: What's to deny?

You ignore the fact thus stuff has never been proven.

You Ask people to trust and believe you on this yet you offer no evidence? That's the basis for religions and not how science works.

1) Anybody can look at page 19 of the 2012 IPCC Final Report and see the 75% error bars in the sole proof CO2 affects climate.

2) Anybody can look up the temperature readings in the NOAA site and verfy for themselves it has not warmed this century.

3) Anybody can read Jouzel 2007 and see that's it's warmed 3X as fast as this in the recent past.

4) Anybody can read Beck 2007 and see CO2 was twice as high as it is now in the 1930s.

I know you think you're right and tryng to help, but, and I know this may come as a shock, but #MediaLies and it's called #Greenwashig

"I hope you're sitting down: Journalism doesn't exist anymore. It hasn't for at least ten years now. The closest thing we have to journalism now is agenda-driven propaganda dressed up as "objective, hard-hitting news." Yes, this includes your favorite muckraking work over at Mother Jones or whatever. Journalism died a pretty sad death, and yeah, we're all kind of bummed about it." - Nicholas Pell

800 peer reviewed papers skeptical of AGW.

The more than 300 additional scientists added to this report since March 2009 (21 months ago), represents an average of nearly four skeptical scientists a week speaking out publicly. The well over 1,000 dissenting scientists are almost 20 times the number of UN scientists (52) who authored the media-hyped IPCC 2007 Summary for Policymakers.

New NASA Data Blow Gaping Hole In Global Warming Alarmism

NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.

September 2013 - A leaked copy of the world’s most authoritative climate study reveals scientific forecasts of imminent doom were drastically wrong.

World's top climate scientists told to 'cover up' the fact that the Earth's temperature hasn't risen for the last 15 years

But leaked documents seen by the Associated Press, yesterday revealed deep concerns among politicians about a lack of global warming over the past few years.

Germany called for the references to the slowdown in warming to be deleted, saying looking at a time span of just 10 or 15 years was ‘misleading’ and they should focus on decades or centuries.

The UN's Intergovernmental Panel on Climate Change has changed its tune after issuing stern warnings about climate change for years

Hungary worried the report would provide ammunition for deniers of man-made climate change.

Belgium objected to using 1998 as a starting year for statistics, as it was exceptionally warm and makes the graph look flat - and suggested using 1999 or 2000 instead to give a more upward-pointing curve.

The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the ‘leading hypothesis’ among scientists that the lower warming is down to more heat being absorbed by the ocean – which has got hotter.

The last IPCC ‘assessment report’ was published in 2007 and has been the subject of huge controversy after it had to correct the embarrassing claim that the Himalayas would melt by 2035.

It was then engulfed in the ‘Climategate’ scandal surrounding leaked emails allegedly showing scientists involved in it trying to manipulate their data to make it look more convincing – although several inquiries found no wrongdoing.

Nasa climate scientists: We said 2014 was the warmest year on record... but we're only 38% sure we were right

The Nasa climate scientists who claimed 2014 set a new record for global warmth last night admitted they were only 38 per cent sure this was true.

In a press release on Friday, Nasa’s Goddard Institute for Space Studies (GISS) claimed its analysis of world temperatures showed ‘2014 was the warmest year on record’.

The claim made headlines around the world, but yesterday it emerged that GISS’s analysis – based on readings from more than 3,000 measuring stations worldwide – is subject to a margin of error. Nasa admits this means it is far from certain that 2014 set a record at all.

Yet the Nasa press release failed to mention this, as well as the fact that the alleged ‘record’ amounted to an increase over 2010, the previous ‘warmest year’, of just two-hundredths of a degree – or 0.02C. The margin of error is said by scientists to be approximately 0.1C – several times as much.

NOAA says 2014 was warmest year worldwide on record; state climatologist John Christy disagrees

"It wasn't the hottest," said Christy, the director of the Earth System Science Center at the University of Alabama in Huntsville as well as the state's climatologist.

While the National Climatic Data Center in the National Oceanic and Atmospheric Administration (NOAA) disagreed, it included climate research from UAH in its report.

According to NOAA, the globally averaged temperature over land and ocean surfaces for 2014 was the highest since record keeping began in 1880. It surpassed the previous high marks by 0.07 of a degree Fahrenheit.

The average temperature across the globe in 2014 was 1.24 degrees Fahrenheit warmer than the 20th century average, according to NOAA.

The conflict is that UAH measures atmospheric temperatures, not surface temperatures. The UAH data focuses on the lowest troposphere - the area between the earth's surface and roughly five miles into the atmosphere.

The atmospheric temperatures, Christy said, indicated that it was the third-hottest year on record - topped by 1998 and 2010.

"2014 was in a cluster of warmish years," said Christy, long known to be skeptical of claims of dangerous global warming. "That cluster is distinctly cooler than the two hottest years - 1998 and 2010."

2015 was supposed to be warmer. Yet even in a hot place like Brazil, things died of cold not heat it got cold enough to kill tropical animals. "Some of the fish were imported from Africa, Asia and Oceania. An Anambi document said 80% of the fish died from a temperature drop as winter approached in Brazil."

Global Warming More Moderate Than Worst-Case Models

A new study based on 1,000 years of temperature records suggests global warming is not progressing as fast as it would under the most severe emissions scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC).

Australia will no longer contribute to major UN climate change fund

Australia will no longer contribute to a major United Nations fund used to combat climate change. Following previous promises by Prime Minister Scott Morrison to no longer “tip money into that big climate fund,” the country made its final $19 million contribution in December, according to budget documents released today and reviewed by Climate Home News. The climate fund Morrison was referring to, the Green Climate Fund, was a basis for the Paris Climate Accord, with wealthier countries agreeing to contribute to projects that help developing nations lower their greenhouse gas emissions.

An Estimate of The Centennial Variability of Global Temperatures

The rate of warming in the 20th century was the same as the rate of warming in the 80 previous centuries.

There has been widespread investigation of the drivers of changes in global temperatures. However, there has been remarkably little consideration of the magnitude of the changes to be expected over a period of a few decades or even a century. To address this question, the Holocene records up to 8000 years before present, from several ice cores were examined. The differences in temperatures between all records which are approximately a century apart were determined, after any trends in the data had been removed. The differences were close to normally distributed. The average standard deviation of temperature was 0.98 ± 0.27 °C. This suggests that while some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations.

97% of climate scientists believe AGW?

No, those statistics, like many others have been fraudulently manipulated, it's actually less than 1%. It's actually 75 people on climate grants, that's why they give the number as a percent. The thing to ask is percent of what?

Big data finds medieval warming period.

There's no compelling scientific argument for drastic action to 'decarbonize' the world's economy. Opinion signed by sixteen scientists.

Thus the BBC is engaged in the extinction of journalism

It never occurred to the BBC to ask who might be behind Extinction Rebellion, since a coordinated world-wide movement like this does not arise through spontaneous action.

Evidence that has emerged so far indicates a cynical alliance between capitalists and anti-capitalists. This piece suggests that behind Greta Thunberg, the movement’s teenage figurehead, lies a powerful non-profit industrial complex which has manufactured and promoted a youth movement in order to “to unlock 100 trillion dollars from pension funds” in the “financialisation of nature”.

This piece by Paul Homewood highlights documents reportedly retrieved from Extinction Rebellion’s computer database which reveal that its aims include “to build structure, community and test prototypes in preparation for the coming structural collapse of the regimes of western ‘democracies’ — now seen as inevitable due to stored-up crisis. Thus preparing a foundation to transform society and resist fascism/other extremes. This includes creating Rising from the Wreckage – a citizens’ assembly based on sortition [random selection]”.

As Forbes magazine noted here, over the past 150 years the world has warmed by a mere 0.8 degrees – and even that has tapered off to essentially flatlining over the last decade and a half.

As climate scientist Vijay Jayara wrote: “There is poor correlation between CO2 emissions and global temperature. Between 2000 and 2018, global temperature showed no significant increase despite a steep increase in carbon dioxide emissions from anthropogenic sources. The same was the case between the years 1940 and 1970. When carbon dioxide concentration increases at a constant and steady rate and temperature doesn’t follow the pattern, we can be certain that carbon dioxide is not the primary driver of global temperature.

Data about temperatures in the USA from the NOAA show that, in six of the past nine months, temperatures were below normal — and the US temperature average is actually cooler now for 2019 than in 2005 when the dataset started. So is global warming only, er, occurring in Europe?

In March, a NASA study found the famous Jakobshavn glacier in Greenland was starting to grow again “after retreating about 1.8 miles and thinning nearly 130 feet annually since 2013,” but is growing the past two years (2016-2018). And for most of the past 10,000 years, the Greenland Ice Sheet was smaller than it is today.

As for the supposedly record number of wildfires, according to NASA global wildfires have dropped since 2003 by 25 per cent.

By this, Taalas meant that deep greens have been abusing the reports of the IPCC, cherrypicking parts that they think will support radical action.

“The IPCC reports have been read in a similar way to the Bible: you try to find certain pieces or sections from which you try to justify your extreme views. This resembles religious extremism.”

What are witnessing is not the imminent extinction of the planet. It is the extinction of reason.

PCC computer models have predicted the global temperatures will rise 1° per decade (Fig. 40A) for the next 10 decades and be 10° warmer by 2100. According to their models, global temperature should have warmed 1° from 2000 to 2011, but global climates have actually cooled, not warmed, since 1998 (Fig. 40B). Thus, the computer models have failed badly in predicting global climates and therefore must be considered unreliable.

As in "lies and deception".

Dr. Patrick Moore is a founding member of Greenpeace and served for nine years as president of Greenpeace Canada and seven years as a director of Greenpeace International

"Linda Prokopy, a Professor of Natural Resource Social Science at Purdue University, surveyed more than six thousand farmers and scientists and found widespread disagreement on human contributions to climate change. While 90 percent of scientists and climatologists surveyed thought the climate was changing, only about 50.4 percent contended that humans were the primary cause of these changes. More shocking was that just 53 percent of climatologists surveyed thought “Climate change is occurring, and it is caused mostly by human activities.”

"This evidence is inconvenient to the many media outlets that have endlessly repeated that 97 percent of scientists endorse the global warming hypothesis. Prominent outlets like NBC and The New York Times, as well as countless others, have effectively shut down debate by asserting there is no scientific debate."

"James Lovelock, the scientist that came up with the 'Gaia Theory' and a prominent herald of climate change, once predicted utter disaster for the planet from climate change, writing 'before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.' Now Lovelock is walking back his rhetoric, admitting that he and other prominent global warming advocates were being alarmists."

A spokeswoman for Trinity College said: "The college respects the right to freedom of speech and non-violent protest but draws the line at criminal damage and asked the protesters to leave.

 So, should we worry or not about the warming climate? It is far too binary a question. The lesson of failed past predictions of ecological apocalypse is not that nothing was happening but that the middle-ground possibilities were too frequently excluded from consideration. In the climate debate, we hear a lot from those who think disaster is inexorable if not inevitable, and a lot from those who think it is all a hoax. We hardly ever allow the moderate “lukewarmers” a voice: those who suspect that the net positive feedbacks from water vapor in the atmosphere are low, so that we face only 1 to 2 degrees Celsius of warming this century; that the Greenland ice sheet may melt but no faster than its current rate of less than 1 percent per century; that net increases in rainfall (and carbon dioxide concentration) may improve agricultural productivity; that ecosystems have survived sudden temperature lurches before; and that adaptation to gradual change may be both cheaper and less ecologically damaging than a rapid and brutal decision to give up fossil fuels cold turkey.

 We’ve already seen some evidence that humans can forestall warming-related catastrophes. A good example is malaria, which was once widely predicted to get worse as a result of climate change. Yet in the 20th century, malaria retreated from large parts of the world, including North America and Russia, even as the world warmed. Malaria-specific mortality plummeted in the first decade of the current century by an astonishing 25 percent. The weather may well have grown more hospitable to mosquitoes during that time. But any effects of warming were more than counteracted by pesticides, new antimalarial drugs, better drainage, and economic development. Experts such as Peter Gething at Oxford argue that these trends will continue, whatever the weather.

 Just as policy can make the climate crisis worse—mandating biofuels has not only encouraged rain forest destruction, releasing carbon, but driven millions into poverty and hunger—technology can make it better. If plant breeders boost rice yields, then people may get richer and afford better protection against extreme weather. If nuclear engineers make fusion (or thorium fission) cost-effective, then carbon emissions may suddenly fall. If gas replaces coal because of horizontal drilling, then carbon emissions may rise more slowly. Humanity is a fast-moving target. We will combat our ecological threats in the future by innovating to meet them as they arise, not through the mass fear stoked by worst-case scenarios.

The difference between fact ("the earth is round"), consensus ("the earth is flat") and manufactured consensus (cherry picking data to produce a "consensus" for the benefit of a few).

A good laymans explanation of how you're being lied to about climate.

A bit of signal in a world of noise.

February 23, 2015 - "The past year was the warmest year on record, though their analysis has 2014 in a virtual tie with 2005 and 2010. "

When several years all tie for the warmest year it means temperature isn't increasing. Or to put it another way, no year even reached 1998's temprature, let alone exceeded it.

Note two things about this graph:
  1. It's got more cold bits than warm bits
  2. It stops rising at the end.

Consider the fact it's part of a longer curve that looks like this:


Public confidence in the AGW hypothesis eroded in proportion to the error in the models. Amusingly, as that error went up so did the confidence factor in them expressed by te PCC in the media.

Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th century

Debate over what influence (if any) solar variability has had on surface air temperature trends since the 19th century has been controversial. In this paper, we consider two factors which may have contributed to this controversy: 1. Several different solar variability datasets exist. While each of these datasets is constructed on plausible grounds, they often imply contradictory estimates for the trends in solar activity since the 19th century. 2. Although attempts have been made to account for non-climatic biases in previous estimates of surface air temperature trends, recent research by two of the authors has shown that current estimates are likely still affected by non-climatic biases, particularly urbanization bias. With these points in mind, we first review the debate over solar variability. We summarise the points of general agreement between most groups and the aspects which still remain controversial. We discuss possible future research which may help resolve the controversy of these aspects. Then, in order to account for the problem of urbanization bias, we compile a new estimate of Northern Hemisphere surface air temperature trends since 1881, using records from predominantly rural stations in the monthly Global Historical Climatology Network dataset. Like previous weather station-based estimates, our new estimate suggests that surface air temperatures warmed during the 1880s–1940s and 1980s–2000s. However, this new estimate suggests these two warming periods were separated by a pronounced cooling period during the 1950s–1970s and that the relative warmth of the mid-20th century warm period was comparable to the recent warm period. We then compare our weather station-based temperature trend estimate to several other independent estimates. This new record is found to be consistent with estimates of Northern Hemisphere Sea Surface Temperature (SST) trends, as well as temperature proxy-based estimates derived from glacier length records and from tree ring widths. However, the multi-model means of the recent Coupled Model Intercomparison Project Phase 5 (CMIP5) climate model hindcasts were unable to adequately reproduce the new estimate — although the modelling of certain volcanic eruptions did seem to be reasonably well reproduced. Finally, we compare our new composite to one of the solar variability datasets not considered by the CMIP5 climate models, i.e., Scafetta and Willson, 2014's update to the Hoyt and Schatten, 1993 dataset. A strong correlation is found between these two datasets, implying that solar variability has been the dominant influence on Northern Hemisphere temperature trends since at least 1881. We discuss the significance of this apparent correlation, and its implications for previous studies which have instead suggested that increasing atmospheric carbon dioxide has been the dominant influence.
