The GISS set comprises surface thermometer records going back to January 1880. It takes a lot a massaging to construct a monthly time series of “global” temperatures that spans 137 years, with spotty coverage of Earth’s surface (even now), and wide variability in site conditions, among other problems that can occur in a not-truly-global or systematically controlled network of thermometers over the span of 137 years. There’s the further issue of data manipulation, the most recent example of which was the erasure of the pause that had lasted for almost 19 years.
The UAH database goes back to December 1978, and consists of readings obtained by a system of satellites. A satellite-based system has obvious advantages over a surface-based system, if one’s objective is to obtain accurate and consistent estimates of Earth’s atmospheric temperature.
There are other databases, including those produced by RSS (satellite-based) and HadCRUT (surface-based). But the point of this post is to compare GISS records with those a satellite-based system, and I have chosen the GISS and UAH systems for that purpose.
In Figure 1 you can see that despite efforts to hide the decline — a cooling trend from about 1940 to the late 1970s — GISS could only muster a long pause in the rise of its global temperature estimates.
(I used December 1978 as the “zero” point for ease of comparison with Figure 2.)
Now look at UAH vs. GISS for the span covered by UAH, namely, December 1978 to the present:
The pause, according to RSS, extended from February 1997 to November 2015. This agrees with the UAH data for that period, which show a flat trend; whereas, the GISS data for that period show a rising trend. Taking the UAH slope as the correct one, it seems that GISS overstates the slope of the pause by 0.0011 degree C per month. Subtracting that overstatement from the GISS coefficient for the entire period gives a new GISS slope of 0.0007 degree C per month, which is close to the UAH slope of 0.001 degree C per month. It is also the same as the GISS slope for 1880-1937 (see Figure 1).
I therefore conclude the following: GISS has been doctored not only to hide the decline from about 1940 to the late 1970s and the pause from 1997 to 2015, but also to exaggerate the rise from the late 1970s to the present.
What is really going on? The recent rise in temperature has been ripped out of context. This is from a post by Dr. Tim Ball (figures re-numbered to avoid confusion):
Recent discussion about record weather events, such as the warmest year on record, is a totally misleading and scientifically useless exercise. This is especially true when restricted to the instrumental record that covers about 25% of the globe for at most 120 years. The age of the Earth is approximately 4.54 billion years, so the sample size is 0.000002643172%. Discussing the significance of anything in a 120-year record plays directly into the hands of those trying to say that the last 120-years climate is abnormal and all due to human activity. It is done purely for political propaganda, to narrow people’s attention and to generate fear.
The misdirection is based on the false assumption that only a few variables and mechanisms are important in climate change, and they remain constant over the 4.54 billion years. It began with the assumption of the solar constant from the Sun that astronomers define as a medium-sized variable star. The AGW proponents successfully got the world focused on CO2 [emphasis added], which is just 0.04% of the total atmospheric gases and varies considerably spatially and temporally…. [I]t is like determining the character, structure, and behavior of a human by measuring one wart on the left arm. In fact, they are only looking at one cell of that wart….
Two major themes of the AGW claims are that temperature change is greater and more rapid than at any time in the past. This is false, as a cursory look at any longer record demonstrates…. The Antarctic and Greenland ice core records both illustrate the extent of temperature change in short time periods. Figure [I] shows a modified Antarctic ice core record.
Figure [I] (Original Source SPPI.org no longer available)
The total temperature range is approximately 12°C (-9°C to +3°C). The variability is dramatic even though a 70–year smoothing average was applied. The diagram compares the peak temperatures in the current interglacial with those of the four previous interglacials. The horizontal scale on the x-axis is too small to identify even the length of the instrumental record.
Steve Goreham shows how small a portion it is in this diagram of the last 10,000 years (Figure [II]).
Another graph shows the same period, the Holocene Optimum, in a different form (Figure [III]).
(Read the whole thing.)
The null hypothesis about “climate change” is that recent warming, whatever its true extent, is of a piece with natural variations in Earth’s temperature. I have yet to read anything that refutes the null hypothesis. A lot of what has been written seems, at first glance, to do so. But it does not do so. It assumes, or aims to prove, a causal connection between the steady rise in atmospheric CO2 that has accompanied the industrialization and mechanization of the world and the coincidental — and halting — rise in the temperature record since Earth began to emerge from the Little Ice Age. Thus the inability of simplistic climate models, which are heavy on CO2 effects, to accurately “hindcast” actual temperature changes, that is, to replicate them from the vantage point of the present.
But most of the public “knows” only the scare story told by the red line in Figure 1. There’s no context. The explanation (“CO2 bad”) is superficial and misleading. But it sells the story that pseudo-scientists and politicians like James Hansen, Gavin Schmidt, Michael Mann, and Al Gore. want to sell. And which is sold with the eager assistance of the pro-big-government media outlets in the U.S. (i.e., most of them). It sells the story that leftists want to sell because it supports their need to control the lives of others through the agency of government.
A SCARE-TACTIC DEBUNKED: THE MYTHICAL, EVER-RISING, 30-YEAR AVERAGE
Our local weather Nazi, of whom I have written before, jumped on his high horse and lectured viewers about the 401 (?) consecutive months of above-average temperatures. He didn’t come out and say it — this time — but his thoughts and prayers are running in the direction of a climatic version of gun confiscation. Just take away those fossil fuels, etc., and Earth will return to its “correct” temperature. In his case, because anything above 75 in Austin is too warm for him, attaining the “correct” temperature would require a return to something like a real ice age.
In any event, the statistic that has the weather Nazi — and other climate hysterics — all a-twitter goes like this. The global temperature for every month since February 1985 has exceeded the rolling, 30-year average for that month. This statistic must be derived from surface thermometer readings, inasmuch as satellite readings didn’t begin until the late 1970s. We know all about those surface thermometer readings: spotty coverage, poor siting (often in locations surrounded by concrete and traffic), missing data, and — worst of all — frequent downward adjustments of historical numbers to make recent decades look hotter than they were. There’s no mention of the “pause” between the El Niños of the late 1990s and mid 2010s, of course.
Here’s something closer to the truth, based on satellite-recorded temperatures in the lower troposphere, from the Global Temperature Report by the Earth System Science Center of the University of Alabama-Huntsville:
Here are the yearly averages:
- The anomalies are small.
- There are many negative values before the onset of the major El Niño that began late in 2014 and lasted until mid-2016. (A negative value means that the reading for a month was below the 30-year average for that month.)
- The effects of that El Niño are wearing off.
Note to local weather Nazi: Give it a rest.
TAKING A STEP BACK — “GLOBAL” TEMPERATURES IN PERSPECTIVE
The “official” GISS set of temperature records (here) comprises surface thermometer records going back to January 1880. It takes a lot of massaging to construct a monthly time series of “global” temperatures that spans 137 years, with spotty coverage of Earth’s surface (even now), and wide variability in site conditions. There’s the further issue of data manipulation, the most recent example of which was the erasure of the pause that had lasted for almost 19 years.
Taking the GISS numbers at face value, for the moment, what do they suggest about changes in Earth’s temperature (whatever that means)? Almost nothing, when viewed in proper perspective. When viewed, that is, in terms of absolute (Kelvin) temperature readings:
Yes, there’s an upward trend of about 1 degree K (or 1 degree C) per century. And, yes, it’s statistically significant. But the statistical significance is due to the strong correlation between time and temperature. The trend doesn’t explain why Earth’s temperature is what it is. Nor does it explain why it has varied over the past 137 years.
Those variations have been minute. The maximum of 288.79K is only 1.1 percent higher than the minimum of 285.68K. This minuscule difference must be swamped by measurement and estimation errors. It is credible that Earth’s average temperature — had it been measured consistently over the past 137 years — would have changed less (or more) than the GISS record indicates. It is credible that the observed uptrend is an artifact of selective observation and interpretation. It has become warmer over the past 30 years where I live, for example, but the warming is explained entirely by the urban heat-island effect.
A proper explanation of the minute variations in Earth’s temperature — if real — would incorporate all of the factors that influence Earth’s temperature, starting from Earth’s core and going out into the far reaches of the universe (e.g., to account for the influence of cosmic radiation). Among many things, a proper explanation would encompass the effects of the expansion of the universe, the position and movement of the Milky Way, the position and movement of the Solar System, and the position and movement of Earth within the Solar System, and variations in Earth’s magnetic field.
But global climate models (or GCMs) focus entirely on temperature changes and are limited to superficial factors that are hypothesized to cause those changes — but only those factors that can be measured or estimated by complex and often-dubious methods (e.g., the effects of cloud cover). This is equivalent to searching for one’s car keys under a street lamp because that’s where the light is, even though the car keys were dropped 100 feet away.
The deeper and probably more relevant causes of Earth’s ambient temperature are to be found, I believe, in Earth’s core, magma, plate dynamics, ocean currents and composition, magnetic field, exposure to cosmic radiation, and dozens of other things that — to my knowledge — are ignored by GCMs. Moreover, the complexity of the interactions of such factors, and others that are usually included in GCMs, cannot possibly be modeled.
- Changes in Earth’s temperature are unknown with any degree of confidence.
- At best, the changes are minute.
- The causes of the changes are unknown.
- It is impossible to model Earth’s temperature or changes in it.
It is therefore impossible to say whether and to what extent human activity causes Earth’s temperature to change.
It is further impossible for a group of scientists, legislators, or opinionizers to say whether Earth’s warming — if indeed it is warming — is a bad thing. It is a good thing for agriculture — up to some point. It’s a good thing for human comfort (thus the flight of “snowbirds”) — up to some point. But for reasons given above, it’s truly unknown whether those points, and others, will be reached. But as they are, human beings will adapt, as they have in the past — unless their ability to adapt is preempted or hampered by costly regulations and counterproductive resource reallocations.
Science is not on the side of the doom-sayers, no matter how loudly they protest that it is.
