Will Breakthroughs Save the Planet?

The dire predictions concerning the probable impact of climate change on ecosystems, ocean-levels, and food-production, as well as on our species itself have understandably been made without taking into account the countervailing impact of technology yet to be invented. Instead, the focus has been on governmental, rather than business, efforts aimed at reducing carbon emissions. This too is understandable, as companies have consistently been oriented to their own profits rather than reducing externalized costs, such as pollution. This focus has left the element of technological innovation or invention out of the equation. Moreover, because it is not possible to predict whether our species will have invented technology in time for it to counter the predicted impacts of climate change, relying on such technology so as to obviate the need to act so as to limit or reduce carbon emissions would be foolish and reckless. Put another way, it was irresponsible as of 2020 at least to say that government restrictions on carbon emissions were not necessary because technology will be invented that will substantially reduce emissions or even remove the excess carbon from the atmosphere. This does not mean that such inventions will not be made in time to make a significant positive impact. It is indeed possible, moreover, that our species, homo sapiens, will be saved by its own knowledge after all, even though we do not seem capable of regulating the innate desire for instant gratification even if the species’ survival lies in the balance. An invention by Heliogen in 2019 was such a breakthrough that it was arguably the first invention capable of giving people such hope. That is, the step-forward represented by the invention was such that people at the time could hope that the most noxious future impacts of climate change might not be inevitable.

Heliogen, a clean-energy company, announced in November, 2019 that artificial intelligence and a field of mirrors could be used together to significantly reduce greenhouse emissions by industry. The invention could generate extreme heat above 1,000 degrees Celsius—a temperature that is about a quarter of that which is on the surface of the Sun. “The breakthrough means that, for the first time, concentrated solar energy can be used to create the extreme heat required to make cement, steel, glass and other industrial processes. In other words, carbon-free sunlight can replace fossil fuels in a heavy carbon-emitting corner of the economy that has been untouched by the clean energy revolution.”[1] These industries were “responsible for more than a fifth of global emissions, according to the EPA.”[2] Accordingly, Soon-Shiong, who sat at the time on the Heliogen board, said, “The potential to humankind is enormous  . . . The potential to business is unfathomable.”[3] Such statements have been unusual, to say the least. They connote hope even beyond their particular instance because they show that such breakthroughs are indeed possible. Indeed, more such breakthroughs would still be necessary to stave off the feared effects of climate change.

Bill Gates, founder of Microsoft, was an early backer of Heliogen. He characterized the invention as “a promising development in the quest to one day replace fossil fuel.”[4] As laudable as this, as well as a titan’s investment in such a widely beneficial venture, is, replacing fossil fuel does not reduce the accumulated carbon (and methane) in the atmosphere. At 410 ppm, the carbon in the Earth’s atmosphere was already highly problematic from the standpoint of eventual harm to the planet. At least at the time of Heliogen’s invention, it would do nothing to reduce carbon that had or would enter the atmosphere (or the oceans). Ultimately, staving off climate change due to carbon emissions would entail extracting carbon (and methane) from the atmosphere and oceans.

Therefore, the breakthrough itself was not enough to relieve governments and businesses from pressure to drastically reduce carbon emissions. Indeed, carbon would continue to accumulate in the atmosphere from the cement and steel industries before the full implementation of the ovens (and storage for rainy days), as well as from business more generally in which the new technology is not applicable. Methane would still be emitted from permafrost as it melts at northern latitudes. In short, the breakthrough could be expected to reduce the emission of carbon while the remaining emissions increase the accumulated carbon in the atmosphere and oceans. Even so, the sheer existence of one breakthrough pertaining to climate change can give us hope that other breakthroughs, even pertaining to reducing accumulated carbon and methane, will happen even if we could not factor them in.

China's Population: Demographic Imbalances and the Climate Emergency

In his treatise on Understanding, David Hume posits that we don’t know as much about causation as we think we do. Often times, positive correlation (i.e., two or more things present at the same time) is confused with causation (i.e., one thing causing another). That umbrellas tend to be out when it is raining does not mean that umbrellas cause rain (or that rain causes umbrellas). Rain and umbrellas have their own distinct causes, which Hume would say we don’t understand as well as we think we do. It is very difficult, for example, to determine whether climate change caused by methane and CO2 emissions caused October 2019 to the hottest October globally on record; more data-points covering long stretches of time are needed to distinguish even a few outliers from being part of a broader trend. By October of 2019, not only had scientists obtained and analyzed enough samples over a long enough time-frame to be confident (99%) that climate change had been occurring due to human carbon emissions. Not since roughly 60 million years ago had the carbon parts per million in the atmosphere stood at 410 ppm. In having to repeatedly accelerate their forecasts regarding the various impacts, such as sea-level rise due to melting ice (on land, such as Greenland), scientists had demonstrated that our understanding of the causation on the various impacts was still far from perfect. Even so, 11,000 scientists knew enough by November 2019 to declare unequivocally that humanity was facing a climate-change emergency. That is to say, drastic changes in terms of carbon emissions (e.g., energy sources, lifestyles) would have to be quickly made to avoid the worst-case scenario (e.g., mass food shortages, mass migrations from coastal areas and the loss of cities, and disease). This scenario is in line with Mathias’ theory of population ecology wherein a population of a species increasing without reaching an equilibrium maximum faces an increased risk of war, disease, or starvation. Once a species’ population pierces the semi-permeable constraints of the wider ecosystem (i.e., natural environment), Nature has its own ways of arresting the schizogenic growth of a species if it fails to limit its increase. During the twentieth century, the global increase of our species’ population was expediential, going from 1.6 to 6.1 billion. Sadly, even many policy-makers were oblivious to the fact that such a huge change must surely have consequences, at least some day. China’s one-child policy was an exception, making the relatively unconstrained population growths in India and Africa more noticeable as potentially problematic. Why did China need its policy while India, also with a population of over a billion, did not? In fact, the growth mantra generally subscribed to by countries across the globe acted as an incentive to make matters worse! Even a population with a low birth rate was generally taken as a problem. The negative impacts on a labor force and economic growth more broadly gave governments an incentive to increase birth-rates and thus populations (even though immigration served as an alternative). I want to look further into the case of China as a means of assessing how seriously the world was taking the climate emergency.

China’s one-child policy, wherein a couple could only have one child, was instituted in 1980 and abandoned in 2015, when couples could have two children (but not more). With one of the lowest fertility rates in the world, China faced the “prospect of fewer and fewer workers to support retirees amid a rising median age.”[1] In other words, the pressure of a temporary demographic bind had come to outweigh concerns about the population level even though 1.3 billion people was a significant part of the species’ distended population level of 7.5 billion.

Considering that as living beings, humans must consume energy, 1.3 billion people cannot but have a considerable impact on how much energy humanity consumes. Even were fossil fuel sources entirely eliminated in China and abroad, food scarcity would still be strained, especially considering that India’s 1.3 billion people are also consuming energy. This goes back to the point that a huge increase in the species’ population must have significant repercussions concerning energy (including food). 

To their credit, even though China’s policy-makers in 2019 were “well aware that a rising crop of retirees threaten[ed] to drain household savings and derail [economic] growth” and that the population could start to decline in 2030, birth limits remained in effect in the two-child policy.[2] Policy-makers argued that technological advances and automation would increase productivity such that fewer young workers would be needed. I submit that the government could step in to increase funding to retirees to take the financial pressure off of their family members who are working. Even absent immigration, demographic tight-points can be managed such that the overall goal of a smaller population is not compromised. Therefore, it is irresponsible to say that China should abandon its two-child policy, even if China’s demographic pinch would turn out to be worse than expected in 2019 when the global population stood at 7.7 billion, heading in the wrong direction!

Given the climate emergency, the scientists strongly advised the world that drastic measures needed to be taken as soon as possible. Correcting for the incredible increase in our species’ population that occurred in the twentieth century can be considered a necessary part of the drastic measures. The world would be wise to offer China assistance (e.g., knowledge) such that the corrective is successful, and to pressure India to make a similar corrective. In the culture of growth, it is important to point out that an economy can be expected to contract as its population decreases significantly. Productivity advances, however, can mean that a lower quality of life does not go with the contraction. Indeed, economic contraction is itself part of the decreased demand for energy that goes with a smaller population. To sustain itself rather than be cut down by natural processes, our species must decrease its demand overall rather than only shift off fossil fuels. The planet contains limited resources, including habitable (and farmable) land. Overpopulation can trigger war, disease, and starvation, and even changes to the atmosphere that could render the planet itself very uncomfortable or even uninhabitable for humans.

Listening to a talk given by a NASA public-relations person, I was stunned that he admitted that in NASA’s view we can no longer rely “on this rock” for the survival of our species. Hence the plans to colonize the Moon and Mars.  My reaction was that those are artificial environments for us, and thus inherent unstable, whereas we are suited naturally to living on Earth—just not 8 billion of us! Getting back in sync with our natural environment seems to me to be vastly superior to relying on artificial environments. The twentieth century—the bloodiest century ever as of its close—can turn out to be a population bubble or a jump in terms of population. The bubble-effect requires our species to push itself back down, whereas a jump goes to a higher-population plateau. China deserves credit for resisting the temptation to see its population increase unabated in the false assumption that economic growth is most important.
