This week’s lectionary gospel reading is from Luke 18:9-14.
Jesus told this parable to some who trusted in themselves that they were righteous and regarded others with contempt: “Two men went up to the temple to pray, one a Pharisee and the other a tax collector. The Pharisee, standing by himself, was praying thus, `God, I thank you that I am not like other people: thieves, rogues, adulterers, or even like this tax collector. I fast twice a week; I give a tenth of all my income.’
But the tax collector, standing far off, would not even look up to heaven, but was beating his breast and saying, `God, be merciful to me, a sinner!’ I tell you, this man went down to his home justified rather than the other; for all who exalt themselves will be humbled, but all who humble themselves will be exalted.”
In the context of the Age of Limits this lesson provides guidance to those of us who communicate the predicaments that we face. People who study issues such as climate change and resource depletion are generally well educated and have had sufficient time to research these difficult, complex and emotional topics. This can lead to a situation where they become like the Pharisee in the gospel reading — they feel superior to those who pay no attention to these topics, often because they do not have sufficient time.
Such an attitude is unworthy. Moreover, it is likely to be ineffective. We need to remain humble and to recognize that others may be making a greater contribution than ourselves, even if they do not talk as much. In particular, we need to recognize the time and effort made by those who are actually doing something about our situation, rather than merely talking about it.
The Year 2050
Throughout this blog and in my book I suggest that we consider building a new Christian theology around the following three points.
- Understand and tell the truth
- Accept and adapt
- Live within the biosphere, both spiritually and materially
Of these, I suggest that the most difficult to grasp is the first one: Understand and the tell the truth. The world in which we live is extraordinarily complex, with many feedback loops (both positive and negative, many of which are neither identified nor understood) and potential tipping points (once more, often not either identified or understood). No matter how much research we may have done, and no matter how well educated we may be in there topics, we return to the need for humility.
For the last few weeks we have concentrated on the realities and implications of climate change — partly because that topic has received so much publicity from that remarkable young lady Greta Thunberg. But climate change is not the only challenge that we face; resource depletion is equally serious. Moreover, the two topics are tightly intertwined with one another. And then we need to add in other issues such as population increase and biosphere collapse. All of these topics interact with one another in complex and difficult-to-understand ways.
But not only is it difficult to determine what will happen, it is even more difficult to figure out when events will occur. One of our truth-telling responsibilities is to provide a timeline, as best we can, knowing that any predictions we make will turn out to be incorrect. In the section entitled The Sadness of Six Degrees at the post Proper 17: The Place of Honor I note that a shortcoming of an otherwise excellent book is that it does not provide dates. It tells us what the Earth may look like as temperatures increase, but it does not provide any estimate as to when these events will take place.
Nevertheless, our political leaders have no hesitation to do with jumping into the fray. Joe Biden, one of the leading candidates in the Presidential election in the United States had this to say,
I guarantee you we’re going to end fossil fuel . . . Before 2050, God willing.
Other candidates have come up with similar goals, so let’s pick on the year that Biden selected — 2050 — to see what the world will look like if his campaign promise materializes.
- All energy currently provided by fossil fuels (oil, coal and natural gas) will be provided by alternative sources. Vice President Biden does not tell us what those alternatives are, but let us assume that they are a mix of nuclear power (fission), wind and solar.
- Since the word “fuel” is used, we can assume that oil, coal and gas will continue to be used for the manufacture of the thousands of petroleum-based products, ranging from fertilizers to chemotherapy drugs to computer screens.
- Implicit in his message is an assumption that no one will be called on to make any type of sacrifice — we will be able to maintain Business as Usual (BAU).
The harsh reality is that, if elected, there is no chance at all that Biden will meet his goal of ending fossil fuel consumption by the year 2050.
We will explore project management and financial realities in future posts. Let’s start with what I consider to be one of the most important articles written this year, Net-Zero Carbon Dioxide Emissions By 2050 Requires A New Nuclear Power Plant Every Day written by Roger Pielke and published by Forbes magazine.
Here is the money quotation from that article.
. . . the math here is simple: to achieve net-zero carbon dioxide emissions by 2050, the world would need to deploy three . . . nuclear plants worth of carbon-free energy every two days, starting tomorrow and continuing to 2050.
. . . some people don’t like the use of a nuclear power plant as a measuring stick. So we can substitute wind energy as a measuring stick. Net-zero carbon dioxide by 2050 would require the deployment of ~1500 wind turbines (2.5 MW) over ~300 square miles, every day starting tomorrow and continuing to 2050.
It is easy to pick on Joe Biden — we are used to political candidates making promises that sound good but that don’t make mathematical sense. But my concern is to do with well-meaning Christians and church authorities. They have fallen into the same trap. If our message is to be convincing then it must also address thermodynamic and project management realities.
Let’s expand on Pielke’s words to do with wind energy.
- We need to deploy 1500 wind turbines EVERY SINGLE DAY, starting tomorrow (his article was written a month ago) up until the year 2050.
- This would require the 300 square miles (78,000 hectares) of land to be converted to wind turbine sites, EVERY SINGLE DAY.
- Therefore we need to dedicate (300 * (2050-2020) * 365) square miles of land to wind turbines in the next 30 years. This is approximately 3.3 million square miles. The area of the United States is 3.5 million square miles (including Alaska). So, starting right now, we need to plan for an area the size of the United States to be dedicated to wind turbines.
- But this is just a start. In her article Understanding Why the Green New Deal Won’t Really Work, Gail Tverberg describes the enormous battery power that will have to be deployed (and then maintained) to allow for the fact that the wind does not blow when we need it. We also need to recognize the wind turbines are complex machines that require fossil fuels for their manufacture and maintenance. Ditto for the electrical grid that they feed into.
If Christians are to provide real leadership in the troubled times that lie ahead, it is vital that they start by understanding the dilemmas that we face. We need to avoid fatalism. But, equally, we need to avoid hopium.
