Ocean cycles, The Pause and Global Warming

By Andy May

h/t Joachim Seifert

There is a new post by Dr. Sebastian Lüning and Professor Fritz Vahrenholt, translated by Pierre Gosselin, on the effect of ocean cycles on 20th century warming and the 21st century pause. They had previously written about this in their popular book The Neglected Sun, in English here. Marcia Wyatt and Judith Curry have also written about the effect of ocean cycles here. These roughly 60 to 65-year cycles have the advantage of explaining the warming from about 1910 to 1944 and the warming from 1975 to 2005 with a similar mechanism. This is important, because the two warming events are very similar, as shown here and in figure 1.

CO2, Good or Bad?

By Andy May

The Earth’s dry atmosphere is 78% nitrogen, 21% oxygen and 0.9% argon. These are not greenhouse gases and they total 99.9%, leaving little space for the greenhouse gases methane and carbon dioxide. The amount of water vapor in the atmosphere varies a lot with altitude and temperature. At low altitude and high temperatures (greater than 30°C or 86°F), over the ocean, it can reach 4.1% (80% relative humidity, 40 deg. C., 760 mmHg pressure) or more of the atmosphere and is less dense than dry air, causing it to rise. It will rise until the temperature is low enough for it to condense to a liquid or solid state and form clouds, rain or snow.

ExxonMobil sues Massachusetts Attorney General

By Andy May

ExxonMobil is suing Massachusetts Attorney General Maura Healey and New York Attorney General Eric Schneiderman, accusing them of unlawfully exercising their powers in a politically motivated investigation of the oil company. The attorneys general have accused the company of misleading investors and the public by withholding internal research about the impact of global warming. A review of publicly available documents from ExxonMobil, both internal and external, did not uncover evidence of any suppressed or withheld ExxonMobil climate research. It appears the company published everything they knew about the subject. They did a lot of research into climate change, but they uncovered no definitive evidence of an impending man-made climate catastrophe and said so publicly. Some ExxonMobil researchers believed that carbon dioxide might be a problem sometime in the future, but they uncovered no definitive evidence of a problem. And, in any case, the concerned researchers presented their concerns to the company management and in public documents, often in peer-reviewed papers. ExxonMobil also had some of their research staff work on every IPCC report.

The attorneys general investigations were carefully coordinated with lawyers and environmental activists in a meeting March 29, 2016. Breakfast and lunch were provided. An attempt was made to keep the meeting secret. Matt Pawa is an environmentalist lawyer who has sued ExxonMobil over climate change and other issues before. An email has him instructing Lemuel Srolovic (chief of the New York Attorney General’s Environmental Protection Bureau) not to confirm his attendance of the March 29, 2016 meeting. Another email shows that there was an attempt to get a signed common interest agreement that restricted sharing information from the meeting. These emails show that there was cooperation between the attorneys general and environmental organizations to “go after” ExxonMobil. The Wall Street Journal has reported that there was an earlier meeting, in January, that included Kenny Bruno (environmental activist with the New Venture Fund) and Bill McKibben (environmental activist, founder of 350.org). The earlier meeting was specifically to plan a legal attack against ExxonMobil, presumably investor Kenny Bruno would profit from this attack.

As a result, ExxonMobil is suing the attorneys general, accusing them of unlawfully exercising their powers to harass the company. The company has asked Dallas federal judge James “Ed” Kinkeade to declare the wide-ranging subpoenas from the attorneys general unlawful. ExxonMobil has already turned over more than one million pages of documents to the New York attorney general Eric Schneiderman.

Federal Judge James “Ed” Kinkeade has ordered Massachusetts attorney general Maura Heally to come to Texas December 13 to answer questions under oath about her office’s climate change-related probe into ExxonMobil. Ms. Healey has strongly objected (court document here) to the summons.

ExxonMobil accuses the attorneys general of coordinating with lobbyists, lawyers and environmentalists:

“to silence and intimidate one side of the public policy debate on how to address climate change.”

One has to wonder how any company or person can be investigated for withholding information on the effects of man-made climate change when a substantial minority of climate scientists aren’t even sure man-made climate change is significant or dangerous. For the views of a few famous climate scientists that do not believe climate change is dangerous see here.

ExxonMobil has previously taken court action to block a subpoena from the U.S. Virgin Islands attorney general and the attorney general backed off of that case. They successfully argued that the subpoena was an unwarranted fishing expedition. The filing states:

“The chilling effect of this inquiry, which discriminates based on viewpoint to target one side of an ongoing policy debate, strikes at protected speech at the core of the First Amendment.”

That is certainly true. This sort of “environmental shakedown” of lawful, productive American companies for profit needs to be stopped. One of the best ways to do this is tit-for-tat. If they go after the company, the company should go after them. We applaud ExxonMobil’s suits and hope they continue the fight. Make this as costly and as embarrassing as possible for New York and Massachusetts!

The U. S. is now a net exporter of Natural Gas

By Andy May

The Wall Street Journal reported today that the United States is now a net exporter of natural gas. We exported an average of 7.4 billion cubic feet (BCF) of gas a day in November, more than the 7 BCF/day we imported. The last time the country did this was 60 years ago, a graph of exports and imports is shown in figure 1.


Figure 1 (From the WSJ)

Shipments from Cheniere Energy’s Sabine Pass LNG facility have grown to 1.5 BCF/day and they continue to add capacity to the terminal. Gas exports have grown more than 50% since 2010 and are likely to increase further by 2020 according to Citigroup and the U.S Department of Energy.

Oil Spills, a Reality Check

By Andy May

A leak in an 8-inch pipeline caused 1,300 barrels (roughly 55,000 gallons) of gasoline to spill near Loyalsock Creek, a tributary of the Susquehanna River in Pennsylvania October 21. This has created a huge stir in the media and frothy statements about the evil and dirty oil companies. But, let’s put this and other pipeline spills into perspective. It has been estimated at Johns Hopkins University by Markus Hilpert that between spills at gasoline stations and on-road incidents, 2 metric tonnes of gasoline are spilled every day in the Washington, D.C. area. If other parts of the U.S. spill the same amount per person, then this means 110 metric tonnes of gasoline are spilled by the public every day. 55,000 gallons of gasoline is 1571 metric tonnes, so this is less than 15 days of normal spills from cars across the U.S.

The Bray (Hallstatt) Cycle

By Andy May and Javier

The evidence for a persistent irregular climate cycle with a period of 2400 ±200 years is strong. There is compelling evidence of a solar cycle of about the same length and phase; suggesting that the solar cycle might be causing the climate cycle. We will present a summary of the evidence, beginning with the original paleontological evidence, followed by the cosmogenic radionuclide (10Be or Beryllium-10 and 14C or Carbon-14) evidence. For more information, a bibliography of many papers discussing topics relevant to the Bray (Hallstatt) cycle can be found here. Only a small portion of the relevant papers are mentioned in this summary post.

The Greenhouse Effect

By Andy May

Originally posted November 2016, edited April 2017 to correct some errors.

We could define the total greenhouse effect (GHE) as the difference between the calculated blackbody temperature of the Earth, about 254K, and the actual average surface temperature, roughly 288K. Using this definition, the average total greenhouse effect on the Earth would be 34°C. The blackbody temperature is supposed to be the temperature of the planet without an atmosphere, but with the same Bond albedo (reflectivity). The Earth is not a blackbody because it stores heat, particularly in the oceans, but this is ignored by some.  The Moon has a calculated blackbody temperature of 270K, no atmosphere, and an average temperature of 250K, so even the Moon is not a blackbody.  Because the atmosphere is transparent to most solar radiation and the Earth’s surface is opaque, the surface of the Earth absorbs twice as much radiation as the atmosphere. Per the laws of thermodynamics, a planet must emit as much radiation as it receives. The Earth’s temperature controls the type of radiation it emits and it emits mostly in the thermal infrared, which is called outgoing longwave infrared radiation, usually abbreviated as “OLR.”

A Review of “25 Myths that are Destroying the Environment”

By Andy May

The new book, 25 Myths that are Destroying the Environment, by Daniel B. Botkin, is a bit light on science and a breezy read. But, it makes some good points. All of us are for clean air and water, but as Peter Schwartz once wrote, the modern environmental movement is “anti-science, anti-technology, and anti-human.” The radical environmentalists of today latch onto mythical assertions that have no basis in fact; but support the idea that man is bad, man is “destroying” the planet and the natural “balance” of nature. Dr. Botkin, an ecologist and biologist of some note, addresses these assertions. He has held positions at Yale, the University of California at Santa Barbara, George Mason University and Woods Hole Marine Biology Laboratory. He is a prolific and well cited writer, this is his 16th book on ecology, the environment and science.

We agree with most of the points in the book, but it doesn’t help that in the foreword to the book, by Alfred Runte, we see the following unsubstantiated and clearly false statement:

“Say everyone believed the Earth to be cooling instead of warming. Would we still not want to curtail the use of fossil fuels? Of course, we would, because they are pollutants.”

This assertion not only contradicts the whole point of the book, which is we need to be skeptical of environmentalist’s myths and look to the facts and science, but it is clearly wrong. Fossil fuels are largely responsible for our current high standard of living, our long life spans and arguably played a significant role in eliminating slavery. As Alex Epstein noted in his book The Moral Case for Fossil Fuels, in the modern world cheap energy from fossil fuels replaces slaves and servants.

“In the past, before modern energy technology, the main way to overcome the problem of human weakness was putting others into a state of servitude or slavery— which meant that only some could prosper, and at the great expense of others. But with machine energy and machine servants, no one has to suffer…”

Cheap energy and the technology it spawned improved the lives of the poor more than the wealthy. When gasoline powered cars were introduced in the late 19th century they were hailed as a clean alternative to transportation by horse and buggy and kerosene provided cheaper, cleaner and safer light at night. Some credit the introduction of cheap kerosene with helping to save whales from extinction. And the truth is the high demand and cost of whale oil (more than $2 per gallon in 1854!) for lamps had drastically reduced the number of whales in the oceans. They only began to recover when the rich switched to cheaper and better kerosene light. The poor of the time either had no light or used camphene or lard. Once kerosene could be distilled from liquid petroleum, thanks to Dr. Abraham Gesner, quality light became available to many more people. Kerosene was 7 cents per gallon in 1895 and whale oil had dropped to 40 cents.

Drought, flooding and plagues claim far fewer lives today due largely to cheap and abundant fossil fuel energy which is used to build irrigation systems, dikes, dams and to deliver clean water. So, with a current population of seven billion people, fed by a green revolution based on natural gas fertilizer, one must ask what would replace fossil fuels? The alternatives are not pretty or reliable, see here and here. It is a shame that a book dedicated to exposing environmentalist’s myths should spread one.

One might want to call fossil fuels pollutants, but it is clear that New York, London and every other large city in the world is cleaner today than in the early 1800’s and the reason is cheap energy from fossil fuels. The rare-earth metals used to make windmills and solar arrays, the chlorine that makes our water and fresh vegetables safe, the batteries in our phones can also be called pollutants. This doesn’t mean we curtail their use. Intelligent choices based on appropriate cost-benefit analysis are necessary. This was a federal judge’s instructions to the EPA recently when he ordered the organization to consider jobs lost when considering air pollution regulations. One shouldn’t say “curtail the use of” anything as important as energy regardless of the facts or consequences. Fortunately, most of the rest of the book is more sensible.

The 25 Myths

The first myth discussed in the book is that man is the only creature that changes the environment. In truth, all creatures change their environment and the environment of the world to some degree. That is how they survive and thrive. The largest changes are made by plants when they produce the oxygen we breath and the wood that we build with and so on.

The next myth is that life and the environment are fragile and man is precipitating the next great extinction event. The Earth has seen five major extinctions. These were all before man evolved and they were truly horrific. The worst extinction was the Permian mass extinction (250 million years ago) when an estimated 70% to 96% of all species went extinct. Myth #3 is that extinction is unnatural, but today there are an estimated 1.5 million species on the Earth and roughly one species goes extinct every year on average. Most species that have ever existed are currently extinct due to the 3.5 billion-year history of life on Earth. But, species persistence is very long, mammals persist for an average of 750,000 years. So, regardless of environmentalist’s persistent speculation; there is no evidence that man is causing an increase in extinctions over the geological norm. Further, extinction is quite natural.

Myths 4 through 11 deal with the “balance of nature” idea. That is nature is in a delicate balance and man somehow screws this up. The reality is nothing in the environment is constant; everything is always changing. Much of this is based on the idea that each population in the environment rises to some “carrying capacity” and can go no further. This is an idea based on laboratory experiments with bacteria in Petri dishes and it only works in laboratories and only with bacteria and other small organisms. In the real world, no population in a real habitat has ever been found to grow according to the “carrying capacity” logistic curve. But, this idea, first expressed in the 19th century, with no observational support, is still the basis of many environmentalist’s assertions.

Nature is not in balance and it has no need of balance. Man, especially land owners and the wealthy want nature to be in balance. They don’t want their property, buildings and houses threatened.

A corollary to the “balance” idea is that we have a perfect set of species in the world today. Each plays a unique role and if any one of these are lost the whole ecosystem fails. Dr. Botkin explains that this is utter nonsense. There are roles to be played in any ecosystem and usually more than one species can fulfill a specific role. Redundancy is a good thing. Competition is a good thing. Some say man is not a part of nature, but is a contaminant. This is not true we are a part of nature, not separate from it. We did not arrive from outer space.

Some would say that people have only changed the environment since the industrial age. However, the archeological evidence says otherwise. As Dr. Botkin explains, there is abundant evidence of man changing the environment for at least the past 30,000 years.

Myth #12: Are people the most important factor determining the Earth’s climate? Dr. Botkin says no. The processes affecting the Earth’s climate are complex and man is only a midget among giants. His discussion of this topic is quite good and familiar to this audience. I direct the curious to the book, he covers the key points well.

Myth #13 is that climate change will lead to a huge number of extinctions. The truth is that even though we are in the Quaternary ice age and have been for the past 2.6 million years, there have been very few extinctions. The climate changes, both warming and cooling, observed in the Quaternary far exceed anything predicted by the climate alarmists for the future, yet only one tree went extinct in North America in that period. Myth #14 is that recent weather is proof of climate change. How this myth persists in mainstream news organizations, like the Economist, when every qualified scientist (alarmists and skeptics) says no weather event can be attributed to climate change is beyond understanding.

Myth #15, consensus is science. Dr. Botkin notes that science is a process of questioning ideas. Scientific statements can be tested and proven wrong, otherwise the statement is not scientific. If the statement survives the tests; it is acceptable and potentially valid. Consensus has nothing to do with scientific validity. One of the problems with the “consensus statement” that man is causing dangerous climate change is it cannot be tested. Thus, the statement is not scientific. Myth #16 is that climate models are accurate. It is bizarre that unvalidated computer climate model predictions are considered “true” by many climate alarmists, politicians and news organizations. They haven’t successfully predicted anything to date.

Myth #17, all populations will grow so rapidly they will exceed their natural limit and then go extinct. Dr. Botkin summarizes the problem with this statement in a humorous way. He quotes Professor of Ecology Larry Slobodkin as saying “being rare is different from going extinct, as the whooping crane said to the passenger pigeon.” Whooping cranes have always been rare, but passenger pigeons which used to number in the billions, are now extinct. Unlike bacteria, the numbers of more complex creatures are not determined only by the food and water supply. In this chapter, Dr. Botkin discusses how many people the Earth could support. This is interesting, but of course he assumes that technology is static, which it isn’t.

Myth #18, predators are necessary to control prey populations. This myth goes back to Herodotus, a Greek historian of the fifth century BC. Predators can reduce the populations of their prey, but they do not control them. Dr. Botkin describes many studies that show the assumed predator/prey relationship (the Lotka-Volterra equations) are not consistent with what is observed in nature.

Myths #19 and #20 are related. The first says if man manages everything correctly he can take the maximum sustainable yield of fish or wildlife every year. The second says that we can’t do much about environmental risk, for example floods and hurricanes. Each year is different and there are many factors affecting fish and wildlife besides hunting and fishing. These factors need to be considered when setting catch limits. Of course, we cannot predict floods, earthquakes, droughts and hurricanes; but we can avoid building in areas where they occur. Or, if we build in dangerous areas we can design the buildings appropriately for the environmental dangers. Being prepared for dangers and planning for them is important. Myth #21 is about forest fires. Forests are very beautiful and wonderful places to live. Unfortunately, it is natural for forests to burn frequently enough so that most of the fuel on the ground is consumed and does not become dangerous to the forest. The normal cycle of forest fires is completely natural and necessary. To live in them one must build very carefully and be prepared.

Myth #22 considers the storage of carbon in forests and using wood as a “renewable” and “carbon neutral” fuel. Dr. Botkin’s conclusion is that current methods overestimate the amount of carbon stored in forests. He estimates North American forests only store 41% of the carbon computed by the IPCC. He also points out that in 2013 the largest “renewable” energy source in Europe was biomass, mainly imported wood pellets from the United States. While the trees cut down and turned into wood pellets can be regrown and new trees will consume the carbon dioxide emitted by burning their parents, the process is not carbon neutral. Cultivating new trees, cutting them down, turning them into pellets and transporting the pellets to Europe emits a great deal of carbon dioxide and burns a lot of fossil fuels. So, obviously, calling this fuel carbon neutral is suspect and issuing carbon credits for burning wood is a fiction.

Myths #23 and #24 are the first of his myths that we disagree with. He claims that solar and wind energy do not require large amounts of land and could provide a “large” percentage of US electricity by 2050. He doesn’t say what “large” means, but we can assume 30% to 40% or more for the sake of argument. He says rooftop solar should be sufficient for most homes and that wind farms don’t need as much land as the critics claim. He doesn’t provide any evidence to back up his claims and they are suspect in our view. For another, more quantitative look at the practicality of solar and wind, I would refer the interested reader to the late Cambridge engineering professor Sir David MacKay’s excellent book Sustainable Energy – Without the Hot Air.

Dr. Botkin refers only to “solar and wind capacity” in his chapter and ignores the need for fossil fuel backup at night and on windless days. We will ignore these rather obvious flaws in his argument because he is missing the larger and more important point of cost. The costs of solar and wind must include fossil fuel backup, electrical grid enhancement to handle intermittent and out of phase power sources, and installation and maintenance. Using batteries to store solar and wind power are out of the question, they are enormously expensive. Germany’s Energiewende goal was to increase their share of renewable energy to 40% by 2050. According to an MIT Technology Review they are very unlikely to make it. In the discussion of myth #24 he uses a German solar energy facility as an example of a northern “successful” facility in a cold climate. Yet, German electricity costs are among the highest in the world and high enough to force factories overseas, often to the US where electricity costs about one-third as much. Siemans moved their oil and gas global headquarters to Houston from Erlangen and their natural gas turbine manufacturing to Charlotte, North Carolina. This move cost Germany 4,500 jobs. Austrian electricity is not as expensive as in Germany, but still over twice as much as in the US. For this reason, Austrian steelmaker Voestalpine built a steel making plant next to Corpus Christi, Texas and shut down a similar plant in Austria due to the lower cost of natural gas in Texas. Germany subsidizes their alternative energy through electricity-bill surcharges, the alternative power financed in this way will cost 25B Euros this year, but will only buy 3.6B Euros of electricity on the open market according to the German economics ministry.

Dr. Botkin’s final myth is that climate change is our most important environmental issue. As he explains, there are numerous other environmental issues that are being ignored due to the current climate change hysteria. Our list does not include the same items as his, but none-the-less we agree that the money spent on climate change would be better spent cleaning our water and air. Further, improving the availability of potable water, electricity and proper sanitation in poorer areas of the world would go a long way toward eliminating serious communicable diseases. These are just a few examples.

Conclusions and opinion

Aside from the flawed foreword by Alfred Runte and the unsupported assertions about wind and solar in myths #23 and #24, the book is generally a good read. It is filled with a lot of interesting anecdotes from Dr. Botkin’s long career as an ecologist. Personally, I would have preferred more data and scientific analysis in support of his conclusions and fewer anecdotes, but then he would probably lose a lot of his audience. Usually, qualified scientists, like Dr. Botkin, once they dig into climate science come to the same conclusion he did. That there is no scientific support for the ideas that man is the major cause of climate change and we are headed to a man-made climate change disaster. I applaud him for speaking out on the subject. His discussion on climate change is technically light, like the rest of the book, but I noticed no inaccuracies and it was a fair treatment of the subject.

The most interesting parts of the book were those that dealt with the ecological myths. These centered around the supposed “balance of nature,” species extinctions and persistence. He is a well-known expert in these areas and it shows. These chapters are very good. So, all in all, I do recommend the book. It is most appropriate for the non-technical reader. Those with a lot of scientific or engineering training may find it a little unsubstantial.

The Economist, fossil fuel subsidies and climate disaster

By Andy May

I’ve been a subscriber to The Economist for years. It is one of the few mainstream media publications I still read. But, I found a very annoying article in the October 1, 2016 issue. The title and link are “Notes from the undergrowth.” It starts out with a false assertion that is easily debunked, but often stated:

Solar variability and the Earth’s climate

By Andy May

According to Javier and the IPCC total solar radiation output varies little, less than 0.1%. This is only 0.7 to 1.4 Watts/m2 and converted to incident radiation striking the Earth this reduces to about 0.05 to 0.4 W/m^2.  The latter values can be compared to an IPCC anthropogenic effect estimate of 2.3 Watts/m2. They believe it has a small effect on the Earth’s climate. Others, like Abdussamatov, think solar output is more variable, perhaps varying 3 Watts/m2 (their Figure 3). Other variable stars, similar to the sun, seem to have 3% dimming in their minima, which is certainly significant. Both of the latter two examples are larger than the IPCC estimate of man’s influence. We don’t want to get any further into this debate here other than to note the IPCC may be significantly underestimating the effect of solar and ocean cycles in their models. The key point is we don’t know what drives the Earth’s climate. There are a bewildering number of natural and man-made factors that influence it.
