    1. Letter to a Liberal member of Parliament

      Dear Mr. Sawatzky,

      Both atmospheric carbon dioxide (CO₂) and temperature are increasing at an exponential rate, in lock-step. Atmospheric CO₂ levels during the Eocene have been estimated up to 840 parts per million (ppm); sea levels were close to 60 metres higher than today. CO₂ concentrations are over 425 ppm and still climbing. Pause a moment to consider what this will mean for all coastal cities.

      What part of “keep the oil in the ground” that scientists have been shouting for decades do politicians not understand? What part of physics are politicians trying to deny?

      I am opposed to allowing more oil tankers near our beautiful, fragile coast. I am vehemently opposed to marring our landscape with pipelines for transporting oil. Yes, $14 trillion dollars is a lot of money, but it will pale in comparison to the economic damage that exacerbating climate change will cause. Carbon capture and storage cannot offset our burn rate with any significance.

      Earth has had a remarkably stable climate for tens of thousands of years; burning fossil fuels is destabilizing it.

      I ask you to acknowledge that physics cannot be bargained with, show some foresight, protect our children's future, and care deeply about our planet's health. I ask that you tell our Prime Minister in no uncertain terms that selling fossil fuels is the wrong choice for the world and the wrong economic direction for Canada.

    2. How are you planning for a potentially bleaker future?

      I think things are going to get a lot worse until they get better (if they do). I’m not talking about US politics (I dont live there), I’m thinking more about climate change: food and water might not be as readily available anymore, never mind other things we take for granted like medicine, transportation, communications, a retirement pension.

      It’s hard to articulate but I feel like our future is bleaker than the previous generation’s for the first time in modern history because of factors beyond our control (i.e. neither geopolitical nor economic). Not sure how to prepare for it so I’m wondering how other Tilderinas and Tilderinos deal with it, especially if you have or are planning on having children?

    3. Letter to Grand Chiefs

      Long ago, Cree leader Captain Swan visited the Athabasca area. In 1715, he described a scene to Hudson’s Bay Company fur trader James Knight: “... there is a Certain Gum or pitch that runs down the river in such abundance that [Indians] cannot land but at certain places.” This was the first written reference to bitumen in Canada. Bitumen forms when organic matter is buried and subjected to heat and pressure over geological timescales. That organic matter was primarily algae and plants, which had sequestered carbon dioxide (CO₂) from the atmosphere by photosynthesis, thereby locking CO₂ in place, significantly reducing atmospheric CO₂ levels, and helping sustain all aerobic life.

      In 1859, John Tyndall explained how atmospheric gases absorb heat from the sun as infrared radiation. His paper details an early understanding of the greenhouse effect. Scientists have long since linked CO₂ emissions—burning refined bitumen and coal—to changing Earth’s climate. A 1912 Popular Mechanics article states, “The furnaces of the world are now burning about 2 billion tons of coal a year. When this is burned, uniting with oxygen, it adds about 7 billion tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the earth and raise its temperature.” A century on, we’re burning 500% more fossil fuels.

      Wishful thoughts will not prevent Earth’s global average temperature from increasing as we combust fossil fuels back into atmospheric CO₂. And while our generation reaps the rewards of inexpensive energy, our grandchildren will face the consequences of repaying this debt. A debt undermining the ancient Haudenosaunee philosophy that today’s decisions should result in a sustainable world seven generations from now.

      Building a better world for our children requires energy—yet doing so by burning fossil fuels to the point of climate destabilization twists irony into generational betrayal far removed from sustainability.

      In a 2013 experiment, University of Berkeley researchers found that breathing in a CO₂ concentration of 1,000 parts per million (ppm) indoors causes a measurable decline in intellectual capacity; at 2,500 ppm, initiative and strategic thinking declined to a dysfunctional level, which has since been corroborated by other researchers, including a 2023 meta-analysis on the short-term exposure to indoor CO₂ levels versus cognitive task performance. These cognitive effects become particularly concerning when viewed against atmospheric trends. On June 2, 2025, atmospheric CO₂ surpassed 429 ppm, a significant increase from the 318 ppm measured at Mauna Loa on June 15, 1959.

      The graph illustrates a troubling acceleration in CO₂ emissions. At the current growth rate of 3.8 ppm per year, atmospheric CO₂ could reach 1,000 ppm in six generations (150 years). A 2021 study published in Nature emphasized the urgent need for action, stating that global oil and gas production must decline by 3% annually until 2050. Moreover, to limit warming to 1.5 °C above pre-industrial levels (1850–1900), an additional 25% of oil reserves must remain untouched.

      Against this backdrop, political leaders advocate for increased fossil fuel extraction. Danielle Smith wants to unlock Alberta’s “$14 trillion in oil wealth” to “benefit millions of Canadians for generations.”

      Short-term economic benefits derived from resource exploitation have repeatedly led to gradual, often unheeded, environmental degradation. This pattern repeatedly culminated in ecological and economic crashes, devastating the very communities who initially profited. Notable cases include Mesopotamian salinization, the Classic Maya collapse, the Ancestral Puebloan collapse, Norse Greenland settlements, Easter Island’s deforestation, the Dust Bowl, the Aral Sea’s desiccation, and the Grand Banks cod collapse. While some nations have sustainably managed resource wealth, the immediate economic pressures and political incentives that drive extraction often overshadow long-term planning.

      The question is not: “How many Canadian generations will benefit?”

      The question is: “How many generations will suffer, globally?”

      Will we learn from history? Will we set an example for the next seven generations?

      Or will we build more oil and gas pipelines, condemning our descendants to an unsustainable future?
