There is a new UN Intergovernmental Panel on Climate Change report. It contains nothing but bad news, of course. But I am busy with my real life; I have obligations to others; I have to feed myself and shower; I even go to the gym regularly. What to do? Just trust a hysterical sixteen-year-old? (Yes, I mean Greta.)
When someone or something claims that there is, has been, change in something I perceive might be important, I apply the following four quick tests. I do this to decide how much I must attention I should pay to the change news.
1 Source credibility
Not all sources are created equal. Some stink, some have a long record of being reliable. The Wall Street Journal is one of the latter. Almost all anonymous internet sources are not even sources. The National Enquirer will publish anything (although it has had a few remarkable scoops). Normal sixteen-year old girls are only credible when they pronounce on show biz stars or on something related to a skill they have personally acquired, such as piano or gymnastics.
2 Main text: description of process
I scrutinize the description at the heart of the announcement of change though only for a short time. Does the process described make sense? Is it derived in an intelligible way from a study, or studies, that conform to conventional scientific, or other scholarly standards? If no claim is made that they do, they don’t, ever. If there is such a claim, there can still be abuse but there will shortly be a denunciation, in most cases, at least.
3 Narrative around description
Most change descriptions not directly in a scholarly journal come wrapped up inside a narrative. The narrative is often more interesting than the findings to which they are supposed to be linked. That’s intentional but dangerous. Suppose your doctor carefully measures your heartbeat and records his observations. Suppose that then, he gives you a very good lecture on the faults of Social Security. However valid the latter is, it should gain no authority whatsoever from the impeccable measurement of you heartbeat. This is a crude example but people do this sort of things all the time. Do you think climate activist do?
I ask myself how tightly connected the narrative is to the straightforward description of the relevant change? Often the answer is: barely, sometimes: not at all.
4 Gauging critically the order of magnitude of change
Suppose I tell you that I have lost weight. (I could use that.) Courtesy requires that you congratulate me but rationality demands that you ask: How much? If my response is one ounce, you will tend to dismiss my announcement and you will be right. One ounce out of 220 lbs is like nothing. (That’s aside from the fact that it might actually be nothing, a measurement error.)
The mysterious issue of “statistical significance” (that I will resist going into here though I am tempted) is only indirectly related to this matter. A difference between before and after, for example, may be statistically significant but yet, completely unimportant.
The short Wall Street Journal piece (1) covering the publication of the report is rich in narrative and short on figures. (That’s usually the case with climate change announcements, I think.) On rare figure drew my attention:
In the past 140 years -covering most but not quite all of the Industrial Age – global surface temperatures have risen by one (unit) degree Celsius.
To give you a practical idea, that’s not enough of a rise to cause me to take off my cotton sweater, or even to unbutton the top of my shirt. If the temperature rose by only one C between 8 am and noon, I would think something was wrong with the weather! I can easily believe that at this rate, in another 1400 years, it will be ten degree centigrade (Celsius) warmer and, we will still be here. That’s unless something else, something much more likely, like an epidemic. wipes us out. (2) and (3).
As this example illustrates, it may often be wise too reverse the critical sequence described above. Why bother to assess the source credibility associated with an announced change, or the conformity of the description change process to good scientific practice, or check out the attachment of the surrounding narratives to the process in the description, why do all this if the measured change is too small to merit attention?
My more complete ruminations on climate change skepticism are in Liberty Unbound: “Climate Change Denier.”

2 I am well aware that this is a sort of arithmetic average. Surface temperature may have gone up more in some areas and less in others. They may have declined in some places. If the subject is dealt with, it will be in: Watts Up with That.
3 The WSJ accounts implies that the UN report is oddly concerned with fisheries. This is odd because fishermen have known forever that there are warm and cool patches at the same latitude in the oceans. They also know that those shift positions and that the positions of such warm and cool patches affect the movements of fish.
Santa Cruz, California is really Silicon Valley Beach. It’s the closest; the next one is quite far. That’s in addition to drawing visitors from deep into the Central Valley of California, and a surprising number of European visitors.
One attractive beach close to its municipal wharf has only two (2) toilets. On Labor Day weekend Sunday, one of the two toilets was out of order. I estimate there were between 500 and a thousand people on that particular beach.
The day before, Labor Day weekend Saturday, the same toilet was already out of order. It was still out of order on Monday, Labor Day itself.
It was only a few months ago that the City of Santa Cruz joined a class action suit by a number of government entities against major oil companies for causing climate change. The first judge to look at the suit send the plaintiffs packing, of course.
So, this city of 60,000 wants to stop global warming but it does not have the ability to place two working toilets at the disposal of hundred of visitors who leave thousands of dollars in its coffers. The city cannot afford to hire a competent plumber on an emergency basis to fix the problem immediately. It does not have the timeX2 that would be required. Make it timeX3 on the outside. The total would come to $500 tops. Make it $1,000. It does not change anything.
The same happened last year or the year before. Surprise!
This is pathetic. We are governed by morons. Their gross incompetence is not natural, I am guessing. It’s learned stupidity. Our fault. We vote them in – with big help from UC Santa Cruz undergraduates who don’t care one way or the other, just want to feel good by electing “progressives.”
No one told our City Manager that Labor Day weekend, and its crowds, were coming. How was he supposed to know?
Although global warming zealots continue their religious crusade, more research reveals skepticism toward the doomsday prophecies. Recently Finnish scientists published research that further debunks claims about the role of humans in generating global warming. Their thesis is that global temperatures are controlled primarily by cloud cover, which is a natural occurance that is beyond human control:
The opponents immediately denounced this as a junk science:
It is OK and normal to have debates within scientific community. We, regular lay tax paying people are understandably not shrewd in all intricacies of scientific debates around so-called climate change. Yet, I am sure many of us want to make sure that no financially ruinous global or nationwide social engineering scheme would be enforced on all of us by social activists who decided to side with a group of aggressive academic zealots claiming scientific consensus and squashing dissenting views.
In his Counterrevolution of Science (1955), F. A. Hayek wrote about the dangerous hubris of “science worshippers” who wanted to extend their theories, which at best had narrow application and limited experimental database, to reshape the life of entire humankind. The first aggressive spearheads of this hubris were “generation X” socialists, acolytes of Henri St. Simone, who congregated in and around Paris Ecole Politechnique from the 1810s to 1860s. They dreamed about New Christianity – a creed based on the religion of science. With its “Council of Newton,” it was to regulate entire life of society. In the past century, we already lived through projects designated to reshape the life of humanity through “scientific” societal laws peddled by Marxism. We also lived through national socialist attempts to breed the better race of human beings based on “scientific” laws. More recently, in the 1970s, driven by the same scientific hubris backed by moral considerations, we resorted to global ban of “evil” DDT. This led to the outbursts of yellow fever and mass deaths in the Third World.
During a brief period of soul searching and self-scrutinizing among the left in the wake of communism collapse in the 1990s, in his Seeing Like a State (1998), James Scott, a leftist academic, gave a severe critique of that hubris that he called high modernism arrogance. Not naming socialism directly and sparing the ideological feelings of his fellow comrades, who have been dominating humanities and social sciences, he subtitled his book as follows How Certain Schemes to Improve the Human Condition Have Failed. Still, it was a devastating accusation of the “science”-based social engineering, from German attempts to breed perfect healthy forests in the 18th century to the “scientific socialism” of the Soviets who methodically ruined Russian agriculture by their aggreesive collectivization. The current left are not as modest as Scott’s generation. They quickly moved on, sweeping their own history under the rug. Being emboldened by the crisis of 2008 (a new “sign” of capitalism end of times), the left are now ecstatic about the Green New Deal and its Stalinist global warming regulations that are peddled by the big-eyed “democratic” socialist of “color” from Congress. It seems we are invited again to step on the same rake in order to smash our forehead once again by adopting another scientific Utopia.
