Big warming, or no warming, depending on dataset

The uncertainty of science: Depending on the dataset, the most up-to-date climate data now shows either no warming since 1993, no warming since 1996, or significant warming continuously since then.

On several different data sets, there has been no statistically significant warming for between 0 and 23 years…. Cl stands for the confidence limits at the 95% level.

The details for several sets are below.

  • For UAH6.0: Since August 1993: Cl from -0.006 to 1.810. This is 23 years and 1 month.
  • For RSS: Since December 1993: Cl from -0.008 to 1.746. This is 22 years and 9 months.
  • For Hadsst3: Since December 1996: Cl from -0.022 to 2.162 This is 19 years and 9 months.
  • For Hadcrut4.4: The warming is statistically significant for all periods above three years.
  • For GISS: The warming is statistically significant for all periods above three years.

The quote above lists all the major climate datasets that everyone in the climate field uses. I’ve rearranged the order from the original to put similar datasets together and thus make it easier to digest the information.

The first two datasets are from satellite data. The Hadcrut datasets both use historical ground and sea surface temperature records and are both produced by the Climate Research Unit headed by Phil Jones, who when other scientists asked him for his raw original data in order to check it admitted that he had lost it. Jones was also one of the scientists whose climategate emails revealed a desire to destroy the careers of any skeptics, prevent their work from being published, and an effort to conceal or change data that contradicted the theory of global warming. GISS is the Goddard Institute for Space Sciences, run for decades by global warming advocate James Hansen and now the source of today’s claims that every month of every year is the hottest ever recorded. GISS is also the NASA institute that has been adjusting past datasets to cool the past and warm the present, thus creating a significantly steeper rise in global temperature than is shown by the original raw data.

Of these datasets, three show no significant warming in the past two decades, while two show significant warming. Which is it? Your guess is as good as mine. However, I must point out that the two datasets that show statistically significant warming have both come under question in the past few years because of questionable science practices, which from my perspective makes their conclusions suspect.

Regardless, even if we accept all of these datasets as completely sincere and honestly obtained, they still are in conflict with each other. Under any reasonably scientific analysis, this tells us that the science here is definitely not settled, and that a lot more work needs to be done before anyone can hazard a guess as to what’s going on with the climate.

The climate fraud at NASA

A German scientist has taken a very close look at the climate data being released by NASA’s Goddard Institute of Space Science (GISS) and found significant and unjustified tampering in order to create the false impression that the climate is warming.

A German professor has confirmed what skeptics from Britain to the US have long suspected: that NASA’s Goddard Institute of Space Studies has largely invented “global warming” by tampering with the raw temperature data records.

Professor Dr. Friedrich Karl Ewert is a retired geologist and data computation expert. He has painstakingly examined and tabulated all NASA GISS’s temperature data series, taken from 1153 stations and going back to 1881. His conclusion: that if you look at the raw data, as opposed to NASA’s revisions, you’ll find that since 1940 the planet has been cooling, not warming.

Ewert’s results confirm what numerous climate skeptics and scientists have already noticed. The raw data shows a cooling trend in recent years, but the released data unjustifiably cools past records while warming recent records to reverse this into a warming trend.

Either everyone at GISS should be fired forthwith, or its funding must cease. They aren’t scientist there, but propagandists for the Obama administration.

66% of all surface climate data is adjusted

The uncertainty of science: An analysis of the surface global weather data, dubbed GHCN and used by NASA’s Goddard Institute of Space Sciences (GISS) to demonstrate the climate has been warming for the past century, has found that 66% of that data is adjusted or estimated and is not based on the actual raw data.

Overall, from 1880 to the present, approximately 66% of the temperature data in the adjusted GHCN temperature data consists of estimated values produced by adjustment models, while 34% of the data are raw values retained from direct measurements. The rural split is 60% estimated, 40% retained. The non-rural split is 68% estimated, 32% retained. Total non-rural measurements outpace rural measurements by a factor of 3x.

The estimates produced by NOAA for the GHNC data introduce a warming trend of approximately a quarter degree C per century. Those estimates are produced at a slightly higher rate for non-rural stations than rural stations over most of the record. During the first 60 years of the record measurements were estimated at a rate of about 75%, with the rate gradually dropping to 40% in the early 1990s, followed by a brief spike in the rate before resuming the drop to its present level.

Approximately 7% of the raw data is discarded. If this data were included as-is in the final record it would likely introduce a warming component from 1880 to 1950, followed by a cooling component from 1951 to the present.

As I have noted previously, all the adjustments cool the past and warm the present, a pattern that is just not realistic in the real world, and could only exist if the people doing the adjustment are either not recognizing their biases or are consciously manipulating the data to prove those biases.

Either way, the surface temperature data as released by GISS is simply not trustworthy for determining the changes in the Earth’s climate over the past few centuries.

Top scientists to review data adjustments of temperature data

The uncertainty of science? A panel of five scientists has been formed to review the adjustments to the global temperature data at NOAA and the Goddard Institute of Space Studies (GISS) that have consistently cooled the past but warmed the present, thus creating the illusion of more warming than the raw data suggests.

Careful analysts have come up with hundreds of examples of how the original data recorded by 3,000-odd weather stations has been “adjusted”, to exaggerate the degree to which the Earth has actually been warming. Figures from earlier decades have repeatedly been adjusted downwards and more recent data adjusted upwards, to show the Earth having warmed much more dramatically than the original data justified.

So strong is the evidence that all this calls for proper investigation that my articles have now brought a heavyweight response. The Global Warming Policy Foundation (GWPF) has enlisted an international team of five distinguished scientists to carry out a full inquiry into just how far these manipulations of the data may have distorted our picture of what is really happening to global temperatures.

The global warming scientists at NOAA and GISS are finally going to challenged to explain their adjustments, something they have so far refused to do. For my part, I will be very surprised if they can come up with a scientifically justified explanation.

“The fiddling with temperature data is the biggest science scandal ever.”

This is a nicely written review of some of the research that Steven Goddard, Paul Homewood, and others have done to uncover the wholesale and unjustified adjustments to the surface temperature data that have been done by scientists at the Goddard Institute of Space Studies and at NOAA. Essentially, the warming of the past half century has been faked by artificially lowering the recorded temperatures of the past while artificially raising the recorded temperatures of the present.

The evidence shows that the data was adjusted to cool the past so that the present looks hotter. The question is: Why were these adjustments made? I can think of no justification, other than fraud and political manipulation.

James Hansen’s Goddard Institute of Space Studies has once again been caught changing its past climate temperature data without explanation.

Surprise of surprise, the change had the effect of making the long-term temperature record support conclusions of faster warming. The biggest changes were mostly pre-1963 temperatures; they were generally adjusted down. That would make the warming trend steeper, since post-1963 temperatures were adjusted slightly upward, on average. Generally, the older the data, the more adjustment.

Hat tip to reader jwing who alerted me to this story. As I commented to him, this “also is old news, to my mind, even though this is a new discovery of corruption. This kind of fraud has now been on-going for the past decade, with no signs of any effort to fix it. Worse, the climate science field even denies that it has a problem. Thus, I don’t trust anything they tell me. I check everything twice, and then have doubts besides. Which is why I remain entirely skeptical of any claims these climate scientists make.”

And in this case, the climate scientist in question is James Hansen.

Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.

A new consensus: Fifty top NASA experts, including astronauts, scientists, and engineers, have issued a letter demanding that NASA stop making global warming claims in press releases and websites.

We, the undersigned, respectfully request that NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites. We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.

The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.

The individuals who signed this letter comprise a who’s-who from NASA’s science and space exploration work over the past fifty years. Their willingness to sign such a letter cannot be dismissed lightly.
