The uncertainty principle and limits of knowledge

[Heisenberg and Bohr] left the park and plunged into the city streets while they discussed the consequences of Heisenberg’s discovery, which Bohr saw as the cornerstone upon which a truly new physics could be founded. In philosophical terms, he told him as he took his arm, this was the end of determinism. Heisenberg’s uncertainty principle shredded the hopes of all those who had put faith in the clockwork universe Newtonian physics had promised. According to the determinists, if one could reveal the laws that governed matter, one could reach back to the most archaic past and predict the most distant future. If everything that occurred was the direct consequence of a prior state, then merely by looking at the present and running the equations it would be possible to achieve a godlike knowledge of the universe. These hopes were shattered in light of Heisenberg’s discovery: what was beyond our grasp was neither the future nor the past, but the present itself. Not even the state of one miserable particle could be perfectly apprehended. However much we scrutinized the fundamentals, there would always be something vague, undetermined, uncertain, as if reality allowed us to perceive the world with crystalline clarity with one eye at a time, but never with both.

No anger! No sadness!

You minimize your feelings and shut yourself down. Emotionally immature parents often react as though your emotions are too extreme: as though there were something wrong with you for having a heartfelt reaction. They thus teach you to downplay your feelings because they are uncomfortable with these strong emotions. They convince you that many of your emotions are unwarranted or excessive.

Their overall message to her was: don’t feel. Whatever Maya experienced, she always got the message that it was too much. Mild emotional arousal was all her parents considered acceptable. To avoid embarrassment, Maya learned to disconnect from her strongest emotions, whether positive or negative. This resulted in chronic depression as an adult. “I think they wanted me to be happy,” Maya told me, “but in a very shallow ‘let’s not get too deep’ kind of way.” Maya recalled that her parents accepted her happiness only about tangible outer-world things they approved of, such as Christmas gifts, new clothes, or a good report card. Maya hid her true reactions because her parents often judged her feelings as excessive, weak, or oversensitive. Because of their rejection, Maya began to minimize and hide her feelings from herself too. She gradually lost her emotional freedom: her right to feel whatever she felt.

Carney on the carbon bubble and stranded assets

By some measures, based on science, the scale of the energy revolution required is staggering.

If we had started in 2000, we could have hit the 1.5°C objective by halving emissions every thirty years. Now, we must halve emissions every ten years. If we wait another four years, the challenge will be to halve emissions every year. If we wait another eight years, our 1.5°C carbon budget will be exhausted.

The entrepreneur and engineer Saul Griffith argues that the carbon-emitting properties of our committed physical capital mean that we are locked in to use up the residual carbon budget, even if no one buys another car with an internal combustion engine, installs a new gas-fired hot-water heater or, at a larger scale, constructs a new coal power plant. That’s because, just as we expect a new car to run for a decade or more, we expect our machines to be used until they are fully depreciated. If the committed emissions of all the machines over their useful lives will largely exhaust the 1.5°C carbon budget, going forward we will need almost all new machines, like cars, to be zero carbon. Currently, electric car sales, despite being one of the hottest segments of the market, are as a percentage in single digits. This implies that, if we are to meet society’s objective, there will be scrappage and stranded assets.

To meet the 1.5°C target, more than 80 per cent of current fossil fuel reserves (including three-quarters of coal, half of gas, one-third of oil) would need to stay in the ground, stranding these assets. The equivalent for less than 2°C is about 60 per cent of fossil fuel assets staying in the ground (where they would no longer be assets).

When I mentioned the prospect of stranded assets in a speech in 2015, it was met with howls of outrage from the industry. That was in part because many had refused to perform the basic reconcilliation between the objectives society had agreed in Paris (keeping temperature increases below 2°C), the carbon budgets science estimated were necessary to achieve them and the consequences this had for fossil fuel extraction. They couldn’t, or wouldn’t, undertake the basic calculations that a teenager, Greta Thunberg, would easily master and powerfully project. Now recognition is growing, even in the oil and gas industry, that some fossil fuel assets will be stranded — although, as we shall see later in the chapter, pricing in financial markets remains wholly inconsistent with the transition.

Sasha’s brain

My youngest brother, Sasha, had a bleed in his brain and is scheduled for surgery in Victoria, BC on March 20th.

My whole family is going to Victoria to support him, including me on Friday.

Remarkably, his friends there have organized a benefit concert for March 15th, to raise money for the physio and speech therapy which he is likely to need after surgery.

He also recently appeared today on a video podcast celebrating Vancouver Island music:

Sasha is a remarkable, caring person who has done a great deal for his students and communities. As frightening as his condition is, it has been impressive and heartening to see his friends bringing such exceptional support.
