Bill Gates’ considerable philanthropic efforts through the Gates Foundation are well known. Much of the foundation’s activity has focused on disease control and nutrition around the globe. Education reform has also been a priority. Many of these projects are laudable, though I’m repulsed by a few (see here and here). During the coronavirus pandemic, Gates has spoken approvingly of Non-Pharmaceutical Interventions (lockdown measures), which are both coercive and ineffective (and see here). He has earned the enmity of anti-vaxers, of course, though I’m not anti-vax as long as the jabs are voluntary. The Gates Foundation funded the World Health Organization’s effort to provide guidance on digital vaccine passports, which is a de facto endorsement of discrimination based on vaccination status. His priorities for addressing climate change also raise some troubling issues, a few of which I address below.

Squeezing Policy from a Definition

Gates put a special Malthusian twist on a TED Talk he did back in 2010 using an equation for carbon dioxide emissions, which he’s reprised over the years. It gained a lot of notice in 2016 when a few sticklers noticed that his claim to have “discovered” the equation was false. The equation is:

CO2 = P x S x E x C,

where P = People, S = Services per person, E = Energy per service, and C = CO2 per energy unit.

This equation first appeared as the so-called Kaya Identity in a scientific review in 2002. Such an equation can be helpful in organizing one’s thoughts, but it has no operational implications in and of itself. At one level it is superficial: we could write a similar identity for almost anything, like the quantity of alcohol consumed in a year, which must equal the population times the ounces of alcohol per drink times the number of drinks per person. At a deeper level, it can be tempting to build theories around such equations, and there is no question that any theory about CO2 must at least preserve the identity.

There’s an obvious temptation to treat an equation like this as something that can be manipulated by policy, despite the possibility of behavioral links across components that might lead to unintended consequences. This is where Gates gets into trouble.

Reality Checks

As David Solway writes, Gates’ jumped to the conclusion that population drives carbon emissions, reinforcing a likely perspective that the human population is unsustainable. His benevolent solution? A healthier population won’t breed as fast, so he prescribes more vaccinations (voluntary?) and improved health care. For good measure, he added a third prong: better “reproductive health services”. Let’s see… what share of the 0.9 -1.4 billion reduction in world population Gates prescribed in 2016 would have come from terminated pregnancies?

In fact, healthier people might or might not want more children, but lower child mortality in the developing world would reduce certain economic incentives for high fertility. Another reliable association is between income and child bearing: an increase in “services per person” is likely to lead to smaller families, but that wasn’t given any emphasis by Gates. Income growth is simply not part of the narrative! Yet income growth does something else: it allows us to more easily afford the research and investments required for advanced technologies, including cleaner energy. These things take time, however.

Solway points to other weaknesses in Gates’ interpretation of the Kaya Identity. For example, efforts to slow population growth are not reliably associated with “services per person”, fuel efficiency, or carbon efficiency. In other words, carbon emissions may be powerfully influenced by factors other than population. China is a case in point.

Centralized industrial and social planning is generally ill-suited to advancing human well being. It’s especially suspect if the sole objective is to reduce carbon emissions. But Gates knows that lowering emissions without a corresponding drop in real income requires continuing technological advances and/or more efficient decisions about which technologies to deploy. He is a big advocate of developing cheap hydrogen power, which is far from a reality. He is also excited about carbon capture technologies, which are still in their infancy.

Renewables like wind and solar power play a large part in Gates’ vision. Those technologies cannot deliver a reliable flow of power, however, without either adequate backup capacity or a dramatic advance in battery technology. Gates over-promotes wind and solar, but I give him credit for acknowledging their intermittency. He attempts to come to grips with it by advocating nuclear backup, but it’s just not clear that he has integrated the incremental cost of the necessary backup capacity with other direct costs of these renewables… not to mention the considerable environmental costs imposed by wind and solar (see the “back-to-nature” photo at the top for a cogent illustration). Power storage at scale is still a long way off, and its cost will be significant as well.

We could deploy existing energy technologies to greater advantage with respect to carbon efficiency. We’ve already reduced CO2 emissions in the U.S. by substituting natural gas for less carbon-efficient fuels, but the Biden Administration would rather discourage its use. Gates deserves credit for recognizing the huge role that nuclear energy can play in providing zero-carbon power. Despite that, he still can’t quite bring himself to admit the boneheadedness of heavy reliance on intermittent renewables.

Bill’s “Green Premium”

Gates seems to have deemphasized the Kaya Identity more recently. Instead, his focus has shifted to the so-called “green premium”, or the incremental cost of using zero-carbon technology relative to a traditional source. Needless to say, the premium is large for truly zero-carbon sources, but Gates emphasizes the importance of using the green premium to guide development even in the here and now.

That’s fine, but it’s not clear that he gives adequate consideration to cases in which emissions, while not eliminated, can be reduced at a negative incremental cost via appropriate substitution. That describes the transition to natural gas from other fuels. This is something that markets can do without the assistance of ham-handed interventionists. Gates prefers nuclear power and says natural gas is “not a real bridge technology” to a zero carbon future. That’s short-sighted and reflects an absolutist mindset that ignores both the economic and political environment. The thinking is that if it’s not zero emissions, it’s not worth doing.

Gates emphasizes the need to sharply reduce the range of green premia on various technologies to achieve net-zero carbon emissions by 2050. But the goal of net-zero emissions 2050 is based on the highly unlikely proposition that global catastrophe awaits failing net-zero. In fact, the predicted consequences of doing nothing are based on drastic and outdated carbon growth scenarios and rudimentary carbon-forcing models that have proven to be severely biased to the upside in terms of predicting global temperature trends.

The idea that 2050 is some kind of “deadline” is a wholly arbitrary determination. Furthermore, the absolutism with which such goals are stated belies a failure to properly assess the true costs and benefits of carbon-based energy. If we so much as accept the notion that fossil fuels have external costs, we are then expected to accept that zero carbon emissions is optimal. This is not “science”; it is doctrine propped-up by bizarre and false scare stories. It involves massive efforts to manipulate opinion and coerce behavior based upon shoddy forecasts produced by committee. Even carbon capture technology is considered “problematic” because it implies that someone, somewhere, will use a process that emits CO2. That’s a ridiculous bogeyman, of course, and even Gates supports development of carbon capture.

Conclusion

I’ve never felt any real antipathy for Bill Gates as a person. He built a fortune, and I used his company’s software for most of my career. In some ways I still prefer it to macOS. I believe Gates is sincere in his efforts to help humanity even if his efforts are misdirected. He seems to reside on the less crazy end of the spectrum of climate alarmists. He’s putting a great deal of his private resources toward development of technologies that, if successful, might actually lead to less coercion by those attempting to transform private energy decisions. Nevertheless, there is menace in some of the solutions to which Gates clings. They require concerted action on the part of central authorities that would commandeer private resources and abrogate liberty. His assertion that the world is over-populated is both dubious and dangerous. You can offer free health care, but a conviction that the population must be thinned can lead to far more radical and monstrous initiatives.

The “green premium” promoted by Gates is an indirect measure of how far we must go to achieve parity in the pricing of carbon and non-carbon energy sources, as if parity should be an objective of public policy. That proposition is based on bad economics, fraudulent analyses of trends in carbon concentrations and climate trends, and a purposely incomplete menu of technological alternatives. Yes, the green premium highlights various technological challenges, but it is also a direct measure of how much intervention via taxes or subsidies are necessary to achieve parity. Is that a temptation to policymakers? Or does it represent a daunting political barrier? It’s pretty clear that the “median voter” does not view climate change as the only priority.

Paris Climate Dance: a Concon

Ah, Paris, we bid you adieu. For both scientific and economic reasons, the Paris Climate Accord is pure numbskullery. We should all be grateful that President Trump has decided to revoke the expensive promises made by Barack Obama under the agreement in a willful effort to appease the world’s rent seekers.

From a scientific perspective, the accord’s prescriptions are premised on a partial effect: absent any feedbacks, carbon emissions would raise the atmospheric temperature slightly. But feedback effects are massively important, as anyone familiar with the climate models’ terrible track record of predictive performance might guess. Water vapor, cloud formation, wind currents, and the response of the Earth’s biomass are just some of the effects that impinge on the relationship between atmospheric carbon and temperatures. In addition, carbon forcings are relatively minor compared to the energy impulses delivered by natural sources, including solar activity and the Earth’s varying axial tilt. Paleoclimate data shows that the world has been this warm before, and warmer.

The economic case against the Paris Accord is even stronger. The very idea that authorities would impose huge material sacrifices on mankind in an effort to prevent a threat for which the evidence is so weak should give pause to any rational individual. Beyond that, however, the real function of the accord was not so much carbon mitigation as it was a shift in the distribution of wealth. This quote of Steven Allen, in a scathing assessment of the agreement, is instructive (forgive his mid-sentence switch to sarcasm):

“Mainly, it’s about taking money from taxpayers and consumers and businesspeople and electricity ratepayers and giving it to crony capitalists, and taking money from people in relatively successful countries and giving that money to rich people in poor countries, to the benefit of members of governing elites who support the Paris deal for the good of humanity and not at all because they expect to line their pockets with it.“

World carbon emissions were expected to keep rising at least through 2030 under the agreement. The subsidies it promised to crony capitalists in the renewable energy industry were to generously fund technologies that are not economically viable without government support, to the detriment of relatively clean-burning fossil fuels, not to mention nuclear power. The U.S. promised to reduce absolute carbon emissions, but the world’s greatest emitter of carbon dioxide, China, promised only to seek to limit emissions per unit of GDP, but not until sometime down the road. That means China’s level of emissions might not reverse, given the rapid growth of the Chinese economy. India’s commitment is similar. And Russia promised a reduction relative to a depressed 1990 level of emissions, which means they have plenty of room for growth.

As for the U.S., where absolute carbon emissions have been decreasing since 2007, the Paris Accord relied on so-called “voluntary” limits to be imposed by federal mandates. Financial demands were made by developing countries under the deal: $100 billion per year. And who would pay for that? Taxpayers in the developed countries, of course. One can only imagine the lust of unaccountable third-world officialdom for those funds. Thus far, the U.S. has paid only $1 billion into the so-called Green Climate Fund, and at least half of that was taken from a State Department account from which disbursal did not require Congressional approval.

Jeffrey Tucker, who is anything but a fan of Donald Trump, minced no words in his assessment of the Paris “treaty”. Here are a few selected quotes:

“The Paris Agreement is a ‘voluntary’ agreement because its architects knew it would never pass the US Senate as a treaty. Why? Because the idea of the agreement is that the US government’s regulatory agencies would impose extreme mandates on its energy sector: how it should work, what kinds of emissions it should produce, the best ways to power our lives (read: not fossil fuels), and hand over to developing world regimes billions and even trillions of dollars in aid, a direct and ongoing forcible transfer of wealth from American taxpayers to regimes all over the world, at the expense of American freedom and prosperity. …

The exuberant spokespeople talked about how ‘the United States’ had ‘agreed’ to ‘curb its emissions’ and ‘fund’ the building of fossil-free sectors all over the world. It was strange because the ‘United States’ had not in fact agreed to anything: not a single voter, worker, owner, or citizen. Not even the House or Senate were involved. This was entirely an elite undertaking to manage property they did not own and lives that were not theirs to control. …

The Paris Agreement is no different in its epistemological conceit than Obamacare, the war on drugs, nation-building, universal schooling, or socialism itself. They are all attempts to subvert the capacity of society to manage itself on behalf of the deluded dreams of a few people with power and their lust for controlling social and economic outcomes.“

The popular fascination with climate scare stories has provided a useful channel of influence for would-be central planners and redistributionists. These social dementors reject the proposition that science is a process of continuing challenge and testing, thereby subverting the very notion of scientific inquiry. They make the laughable claim that 170 years of temperature data, much of which is quite sketchy, is sufficient to draw strong conclusions about the trends and dynamics of the climate on a four billion year-old planet.

Even worse, the climate alarmists insist that they have a monopoly on scientific knowledge, despite a significant share of skeptics in the climate science community. But in pursuit of that monopoly, the alarmists have gone so far as to undermine the integrity of the peer review process in the climate literature and to manipulate temperature data to exaggerate recent records. They have promoted the false claims that cyclonic storm energy has increased with carbon concentration and that sea levels are rising at an increasing rate. (Coastal property values don’t seem to reflect those concerns.) They would have us confuse actual climate data with model predictions, and they continue to offer prescriptions based on carbon-forcing models after many years of terrible forecast performance. They claim that a small increment (one part per 10,000) to the concentration of a trace atmospheric gas will dominate other forces exerting far greater variations in energy. They ignore the benefits that an increase in nourishing carbon dioxide and warming can provide. And they make the anthropocentric claim that a costly sacrifice by mankind, in an attempt to reduce that trace gas slightly if at all, will pay off reliably by reducing global temperatures, despite the very modest claims on those grounds by the Paris Accord itself.

Warm, Contented Civilizations

AGW, Andy May, Carbon Concentration, Human Civilization, Ice Core Data, Little Ice Age, Minoan Warm Period, Perihelion, Roman Warm Period, Temperature Proxy, Viking Civilization, Watt's Up With That?

Human civilizations have experienced many of their worst trials during periods of cooling and cold temperatures over the past 8,000 – 10,000 years. These were episodes associated with droughts as well. Conversely, civilizations have tended to prosper during warm, wet periods. These associations between human progress and the natural environment are discussed in a pair of articles by Andy May: “Climate and Human Civilization Over the Past 18,000 Years“, and “Climate and Human Civilization for the Past 4,000 Years“. The articles are part climate science, part history, and part anthropology, with many fascinating details.

May presents large charts that can be downloaded, and they are especially interesting to ponder. He uses historical temperature proxies from Antarctica and Greenland to construct the charts, along with more recent data on measured surface temperatures in Greenland. According to May, the proxies are highly correlated with other proxy data from less extreme latitudes. Several important takeaways are the following:

Warm periods in the historical record are associated with wet conditions, and cold periods are associated with dry conditions. This is intuitive, as warm air holds more moisture than cold air.
There are estimates of temperatures going back more than 800 million years; apparent cyclical regularities in temperatures have lasted as long 150 million years. Cycles within cycles are evident: a 100,000 year cycle is prominent as well as a 25,000 year cycle (see #4 below).
Today’s temperatures are not as high as those prevailing during about 200 years of the so-called Roman Warm Period, or during a span of similar length in the so-called Minoan Warm Period, about 3,300 years ago. Today’s temperatures are much lower than estimates for much of the earth’s pre-human history.
The southern hemisphere has more volatile temperatures than the northern hemisphere due to the tilt of the earth’s axis at perihelion in January, when the earth is closest to the sun. That means the southern hemisphere tends to have warmer summers and colder winters. That will reverse over the next 10,000 years, and then it will reverse again. There is more land mass in the north, however, so it’s not clear that less extreme weather in the north helps explain the hugely lopsided distribution of development and population in that hemisphere.
Recent increases in sea levels have been small relative to the years following the Little Ice Age. Projected increases over the next 50 years are of a magnitude that should be easily manageable for most coastal areas.
Atmospheric carbon concentration seems to lag major increases in temperatures by about 800 years, raising a question of causality. Today’s carbon concentration is low relative to earlier epochs; it has been increasing for thousands of years, clearly independent of human activity, and is now near 400,000 year highs.
Civilizations have blossomed with warm temperatures and they have collapsed or hit extended periods of retarded progress with declines in temperatures. Human agriculture was born as temperatures rose out of the depths of a glacial period about 10,000-12,000 years ago. Rome flourished during a warm cycle and collapsed as it waned. The Vikings settled in Greenland and Newfoundland during the Medieval Warm Period and were eliminated by the Little Ice Age. May cites a number of other examples of temperature cycles bringing on major shifts in the course of human progress. There are many possible explanations for the decline of past civilizations, but extremely low temperatures, droughts, and lengthy periods of weather inhospitable to agriculture have been important.

The fashion today is to insist that only dramatic changes in our use of energy can avert a global warming catastrophe. It is not clear that any effort by humans to manipulate global temperatures can overcome the natural forces that are always driving temperature change. For that matter, it is not clear that carbon dioxide is a bad thing, or that diverting vast quantities of resources to reduce it would be wise. CO2 is certainly not a pollutant in the normal sense of the word. Here is an excerpt from May’s conclusion in his “4,000 years” article, which speaks volumes:

“First, there is no perfect temperature. Man, even in pre-industrial times, adapted to a variety of temperatures and he has always done better in warm times and worse in cold times. Second, why would anyone want to go back to the pre-industrial climate? The Washington Post says the goal of the Paris Climate Conference was get the world to agree to limit global warming to less than two degrees above pre-industrial temperatures. Pre-industrial times? That’s the Little Ice Age, when it snowed in July, a time of endless war, famine and plague. According to the Greenland ice core proxy data, temperatures 180 years ago were nearly the coldest seen since the end of the last glacial period 10,000 years ago! Why measure our success in combating anthropogenic warming, if there is any such thing, from such an unusually cold time?“
