Chapter 11 The Climate Crisis
For 11,000 years, the stable Holocene era has afforded humanity the playground to thrive. Now we have created the Anthropocene which is driven by human impacts on the planet. Carney does not go into any counter-arguments to say that the impact of human activity on the planet is correlated 1% with climate change or 99%…for him the data is conclusive. In the 1850s, the Industrial Revolution drove up global temperature averages by 0.07 degrees Celsius per decade. The planet’s average temperature is up by 1 degree Celsius since the 19th century.
Other climate changes noted
- The oceans are 30% more acidic since the Industrial Revolution;
- Sea levels have risen 20 centimeters in the last 100 years;
- The 5th mass extinction has shifted to the 6th with extinctions at a rate that is a hundred times higher than an average from millions of years;
- There has been a 70% drop in mammals, fish, birds, amphibians and reptiles since 1965, assuming evolution is not at play, although how do you define evolution?;
Now, market prices of assets are being impacted. Climate change is likely creating:
- a. a feedback loop of rising sea levels,
- b. massive human migration away from rising coastal sea levels,
- c. extreme weather events that are damaging insured property,
- d. More impaired assets on the balance sheets of companies,
- e. A reduction work productivity with the lethal heatwaves,
- f. Global conflict over scares resources,
- g. collapse of coral reefs destroying the livelihood of 500 Million people and ¼ of all biodiversity,
- h. Increased regime change,
- i. Increased citizen unrest,
- j. Increased spread of disease
What is the cause?
The UN’s Intergovernmental Panel on Climate Change (IPCC) has argued that there is a 95% chance that human activity is CAUSING the global warming / climate change. The release of GhGs (Greenhouse Gases) with the most problematic being CO2 which, during rapid industrialization and growth has meant that over 250 years, humans have burned ½ trillion tons of carbon. Trends suggest another ½ trillion could be released in the next 40 years…¾ of the warming impact of emissions is CO2, with the remainder being methane, nitrous oxide and fluorinated gases. Trees cannot carbon capture to rebalance. Temperature and CO2 emission move roughly together, therefore we know what the carbon budget ie. the amount of carbon dioxide that be released into the atmosphere before temperature thresholds are surpassed.
The planet as a system would accelerate into a dangerous feedback loop if average global temperatures go past 1.5 degrees Celsius. The IPCC predicts that if temperatures reach 2 degrees Celsius above pre-industrial levels then 1) sea levels could risk 10 centimeters, 2) ¼ of all people could experience severe heat waves, 3) coral reefs will die off almost completely… 4) permafrost could further unlock CO2 and methane accelerating the trends would blow the budget wide open.
Carney advocates a stabilization of temperatures at 1.5 degrees Celsius. above pre-industrial levels. To do that:
- Emissions have to fall by a minimum of 8 percent for the next 2 decades….
- We release about 42 +/- GigaTons of CO2 per year,
- Planetary budget is 420 GigaTons of CO2 remaining before we hit 1.5 degrees Celsius and 1500 GigaTons of CO2 before we hit 2 degrees Celsius..
Children born in 2021 will have to generate ⅛ the amount of CO2 emissions compared to baby boomers into order stay on carbon budget of 420 GigaTons of CO2 remaining before we hit 2 degrees Celcisu. We need to reduce excess carbon from:
- Industrial processes are 30%
- Buildings 18%
- Cars 17%
- Energy generation 17%
- Agriculture 10%
To reduce GhG, the solutions must
- Change how we create energy (fossil fuels must shift to renewables);
- Change energy usage (decarbonizing industrial processes, increased energy efficiency for buildings);
- Increase the carbon capture, use and storage (and maybe terra forming, although Carney doesn’t mention this)….
Basically, we need to convert the creation of all industrial process to electric and then shift the source of electric from fossil fuels to renewables. The first step may appear impossible considering the amount of energy needed to manufacturer most items in our homes, however that’s what has to happen. Bill Gates details the technologies needed in his book “How to Solve the Climate Crisis.”
Geography of Emissions
most pollution is from cities. By region its:
- China 28%,
- Asia – Other 16%
- USA 15%
- EU-28 10%
- India 7%,
- Russia 5%,
- Japan 4%,
- Europe – Other 3%,
- Africa 3%, Canada 2%, Australia 1%
The Consequence of Climate Change
How much do we value the future? The estimates of the costs of climate change and value of the sustainability contain many uncertainties that enable doubters. The GDP, employment and wage impacts are one way (a 25% reduction in GDP at the tipping point of 3 degree Celsius), the net present value of all future cashflows. What we really value such as the lives of species, livelihood adaptation, birth rate drop aren’t easily monetized.
How central bankers view climate change? There are two types of risk
- physical risks
- transition risks
Risk Type 1: Physical risks =
increased rate of climate and weather related events (storms, fires, floods). The underwriting risk shows that the entire livelihoods buckle as inflation adjusted losses have increased over 8x over the last few years.
- Insurers are in the front line of climate change, beach houses aren’t getting insured at the prices they were 10 years ago.
- The insurance sector is adjusting and pricing-in some climate change using various projected models, subject to re-writes like any other model…Carney feels that coupling “sophisticated forecasting, forward-looking capital regime and business models built around short-term coverage has left insurers relatively well placed to manage physical risks” (277, Value(s)).
- Carney argues that there areas of the economy that will need a public backstop because insurance companies will not insure those areas between $250 Billion and $500 Billion on the US coastal property by 2100.
- Insurers and reinsurers are expecting trouble, Lloyd’s of London has a 20cm assumption which coupled with a hurricane would cause Manhattan damage that is 30% more severe than Hurricane Sandy.
- Coastal flooding is projected to rise by 50% by the end of this century.
- Lethal heatwaves are projected to effect 1.2 billion people annually by 2050;
- The Network for Greening the Financial System (NGFS) is an 80 central bank strong group that have created representative scenarios to show climate risks may evolve affecting the real and financial economies:
- Hothouse earth shows that at 3 degrees Celsius, sea levels rise x cm and extreme weather events result in a 25% GDP loss by the end of the century.
Risk Type 2: Transitional Risk
The second category of costs of risk. The costs and opportunities are more apparent as the crsis worsens and impositions become more overarching:
There will be stranded assets
- Tropical deforestation of palm oil, soy, cattle and timber is for commercial use 70% of the time.
- Automotive industry that will, in Carney’s mind, be disrupted by electric vehicles, driverless vehicles and car-sharing services.
- Coal producers have gone bankrupt in the US.
- Demand and Supply Shocks: demand shocks affect consumption, investment, government spending and net exports in the GDP = C + I + G +(X – M). Demand shocks are short-term usually and therefore don’t effect the productivity of the economy. Supply shocks effect growth, the growth of labour supply, physical capital, human capital and natural capital and the degree of innovation in the economy. So the impact of climate change on GDP is very tough because the sample of prior shocks also contained policy adjustments …
Calculating the Impact of Climate Change on GDP
- Feedback loops amplify quickly and suddenly (ice melting off of the antartica rapidly) and the north pole, it’s dynamic and not inherently predictable even if there is no human variable in the atmosphere itself (all chemistry, geology and hard sciences):
- The relationship between GDP and temperature is not linear;
- Do physical climate events actually have a negative effect or simply impact growth (feedback loops and bad social impacts);
- The degree of adaptation and innovation to mitigate the impact of climate change could be much more significant (i.e humans turn a disaster into a strength leading to more prosperity due to new opportunities that are created).
- Factors like the mass climate refugees which could be over 200 million people, the poorest being dislocated.
- The 6th Mass Extinction: the biodiversity that provides natural capital from the Amazon to the coral reefs will be effected.
For Carney, it is a big deal that the CEO of Shell (Sir Mark Moody-Stuart) says that the probabilities of climate change’s negative impact on humanity is 75% and acknowledges that despite that uncertainty in predicting climate change, Moody-Stuart through the course of his career made larger strategic bets with much lower probabilities…
For Carney, climate change is a ‘tragedy of the horizon.’ The worst impacts are beyond the life-span of the decision-makers of today. The horizon is beyond: the business cycle, political cycle and central bank cycles.
- The horizon of central banks is 2 to 3 years.
- The horizon of financial stability is about 10 years.
- The horizon of political decision-making is about 4 years.
The benefits of mitigating greenhouse gases which stay in the atmosphere for centuries is massive, but for the people who don’t vote today, because they don’t exist yet. “Halving emissions over 30 years is easier than halving them in a decade.” (285, Value(s)) The welfare of future generations should not be discounted as heavily as the financial calculations typically demand.
The rate of adoption of new technology has three phases; 1) research and development, 2) mass adoption, 3) maturity. The rate of S-Curve over the years has been accelerating. James Watt who invested the stem and in 1769 did not see coal over take peatmoss until 120 years later in the 1900s (technically, Watt died before see that development). So, technology to tackle climate change is emerging at quicker paces. The S-Curve needs a nudge from the market as well as the public sources of capital investment.
Tragedy of the Commons
The original example is the unregulated grazing rights on the common lands of Ireland and England in the 19th century there was a negative externality in which a decision is taken which then effects others who aren’t party or even benefit from that decision, is taken. We, the consumer, and we the producer don’t pay for the CO2 emitted to produce most goods. Other examples:
- 1) Overfishing to the point at which that stock of fish is depleted (Cod on East Coast of Canada);
- 2) Deforestation to the point where the forest is spoiled (Easter Island…);
- 3) Commons grazing to the point where the land was destroyed…
Three solutions to the Tragedy of the Commons:
- Pricing the externality: putting a price on carbon. This has only worked well in theory. There is a price of $15 per ton but you would need $50 to $100 per ton to meet the Paris Accord target…
- Privatization of the public spheres: Public grazing lands in the UK to privatization however this created a wealth transfer to those who had the right to charge a fee.
- Supply management by the community to cooperate or regulate the scarce resources there in. Popularized by Elinor Ostrom (1933 – 2012) as economic governance. Get political consensus with shared management.
Carney goes on to draw the analogy that COVID is like climate change, it is a global problem. But climate change has no boundaries at all. Now, there are echoes of Bretton Woods style nationalist self-interest, huge debts and new institutions to tackle climate change:
- 1992 – Rio Earth Summit; a good start..
- 1997 – COP (conference of the parties) 1 and 3 the Kyoto Protocol: Kyoto was flawed, didn’t have teeth, a more serious call to action;
- 2009 – COP15 the Copenhagen Accord flawed, advanced countries pledge financial flows to reduce emission in poorer countries;
- 2015 – COP21 the Paris Accord, more stakeholders, financial firms, turning the agreement into legislative objectives as the UK did (already a low emitter, but limited recycle programs and lots of trash in the streets)
Our political systems don’t overcome these items. True leaders are stewards of the system. Leadership is about being custodians.
Current Financial Sector
Financial markets aren’t really pricing in a carbon price transaction. There is a low urgency effort that will lead to hot house earth, according to Carney. Most financial energy numbers don’t use a price test for their carbon stress test of capital investment They usually use a static price. Their prices are well below the medium to get to zero. BP has $100 per ton in its internals. Only 4% of banks and insurers think these climate risks are being priced accurately. Only 16% used a dynamic price.
Transition Pathway Initiative (TPI) is a consortium of thirteen + five asset owners/managers that are trying to better understand the transition to low-carbon impacts investment strategies. They also launched the FTSE TPI (Climate Transition Index) to articulate who is on the right side of history in Carney’s mind. Investors are shifting capital away from hydrocarbon investments incrementally suggesting that they are pricing in a transition. In other words, the markets are responding to something akin to inevitability about a low-carbon economy. But these are strategic bets, it doesn’t mean they are certain. Moody’s “recently identified sixteen sectors with $3.7 trillion in debt with the greatest exposure to transition risk” (297, Value(s)).
- § For the Goldman Sachs, capital expenditure in oil and gas is being hindered by this transition of asset manager value in oil and gas. Major projects have been mitigated by 60% over the last five years, big oil is moving to big energy.
- § Portfolio managers are engaging and pulling down their oil and gas investment incrementally. Also, in part due to the collapse of prices.
- § Transition bonds. In the fullness of time, climate change will incentivize brown companies to raise capital for green innovation.
- § Carney argues we cannot diversify away from climate change.
- § For Carney he argues that we need financial markets to build a virtuous cycle, better pricing for investors and smoother transition.
- § Sustainable financial systems are being built and the next chapter discusses this in more detail.
Analysis of Part 2 Chapter 11:
- After An Inconvenient Truth (2006), most of the emphasis was on awareness coupled with government intervention. Stephane Dion in Canada led the Liberal Party to massive defeat in 2009, a campaign built on a Green Shift. Of course a myriad of variables determined that election which is why blaming the Green Shift is a political statement that Canadians “don’t really care about climate change” which obviously varies as an opinion per Canadian. Such is our complex world… However, the lesson taken there is that the idea that government and by extension the civil service and regulation are primary means of driving punitive costs to polluters has always been deemed suspect by the smart-money folks. Obama was hands off for example because of the coalition he had backing him and the legislative strategy he needed to implement. And his biography, his mother knew that jobs were more important then environmental for poor Indonesians that she worked with for years. Now, financial institutions, which enable the allocation of scarce capital in as optimal a manner as possible, are being marshalled (by the general investment customer base) to more seriously address climate change + the general investment. Carney does not put the most devastating case forward because it gets harder and harder to know how that would play out in a complex eco-system such as our planet. But basically, after the sea levels rise 10 cm….10 cm or 20cm? So what? We were talking about 20 feet in 2006. So he has to combine weather with flooding to say Hurricane Sandy would have been 30% worse than it was from an insurance perspective. I feel so bad for insurance companies having increase their rates….not!
- Just how bad is this going over 2 degrees Celcius? It’s a prediction but it seems likely that Earth could actually cook-up with this accelerated feedback loop to the point where the Antarctic ice sheet completely melts and we’d all have to learn the breast-stroke…We might even develop gills…..okay, that’s a stretched. But I don’t know if people get how serious climate change consequences are….at that point, we would start seriously looking at terra forming: either dropping the global ocean level by moving ocean bed onto non-Arab land or deploying white reflective material at the poles to bounce more light back up or sprinkle dust into the sky as Bill Gates mentions…
- Carney seems to have removed the claim that water levels would rise 20 feet…..I’m not sure why his book doesn’t mention this often quoted measurement?
- In India, hardworking people are paid much less then a Canadian is paid. What does Carney have to say about inequality? Or post-materialism?
- Alberta conversation, needs a better answer around some support system, although historically when a sector struggles we do not necessarily intervene, but with climate change, government is intervening to accelerate the transition.
- What if the scientists are wrong? How much punishment to be allocated to their grandchildren for the lives hindered incorrectly? The climate physics is rock solid but its an important philosophical question. What commitment can Carney truly make?
- The problem is that in the long run you’re dead. The future is discounted to zero once dead. There is no proof that any other person exists, Berkley style / simulation.
- The Yeah But…a lot of the public still can’t connect this slow moving crisis to their lives, most people see this is a transitionary problem over decades and decades, predictions have been wrong and continue to be wrong, if saving humanity was so lucrative then why haven’t we paid to terra form the planet to prevent sea level rising: there is a funding problem: no one wants to pick up the cheque, where is the global fund to pay for these changes, you are asking people to suffer for an abstraction that isn’t flawlessly defined…
- Carney fails to address the command economy advocacy imbedded in prescribing with science what every person’s carbon footprint ought to be. Here, there is no invisible hand, the government of the world is most equipped with providing each citizen with their responsibility. The counter by Carney is of course, seatbeats wouldn’t have been imposed with political and regulatory force. It is the use of that force that can spur innovation in concentrated points throughout the economy.
- Putting a price on pollution is like putting a price on negative social media comments, the state is imposing a costs for doing something that perceived as bad but has some positive value (_ and making the receiver stronger.
- A general rule in life is to identify that if someone is claiming that there is a single cause to a problem, they are trying to convince you of something, sell you something. The language problem is best exemplified with climate change discussions. Human activity has caused climate change immediately sounds misleading because the “climate is always changing” and how does one know to what degree “human activity” is contributing to climate change. The counter argument that human activity is not causing climate change conflates causing with contributing. If someone says human activity is not contributing to climate change then that’s a sniff test for an intellectual lightweight as well. To prove that humanity is contributing to changes in the environment apply the counterfactual of the no-humans version of earth. In that version of earth, on this day, you would now be outside rather than in your home or office where you are reading this article. There would be no roads, etc etc. All those human tools and technology requires heat energy to produce. That heat energy generates CO2 amongst other gases. So if any one says that humans do not contribute to climate change, they necessarily have to deny that absent humans there would be roads, houses mysteriously populating this no-humans version of earth.
- Carney neglects to acknowledge that the research cited is subject to grants. If someone is obsessed with derivatives, then they will likely think derivatives are really important. They will have biases that warp their world to the point where their own brain notices patterns elsewhere that relate back to derivatives: this is confirmation bias. To not acknowledge that any human being, regardless of credentials is subject to the same confirmation bias should they study climate change, is intellectually controlling. I suspect Carney knows there should be some doubt but he may not trusts readers with this nuance.
- Carney doesn’t have an entrepreneurial spirit really, if he did he would understand that extinction is a necessarily part of evolution. If the cause is human habitat encroachments which by definition is going to continue to happen, then we should be sympathetic. However, extinction is not by definition bad. Does anyone miss Pan-American Airlines? Does anyone miss the Dodo Bird? Of course, we all miss these things or would like to see them in the wild but the cause of their disappearance cannot be 100% human activity alone, but definition we live in a mult-variate world.
- Measuring the acidity of the oceans: a 30% increase in acidity is significant if the acidity of the acid content is 1 -> 1.3 part per 100 but not if it is 1 0> 1.3 part per 1M….
- Carney does not mention that there is an increase in human habitats such that extreme weather events like flash flooding are on the rise…in geographies where the events are newsworthy. An analogy might be that coverage of gun violence is only newsworthy when a random citizen is the victim rather than a gang related victim.
- Carney does not address terra forming solutions accept for the socially accepted one: carbon capture which involves sucking carbon out of the air or releasing CO2 into the ground.
