The climate revolution: a manual for head, hands and heart

Also published at

How many people in North America and Europe have known for at least 15 years that climate change is dangerous, that it is caused mostly by our burning of fossil fuels, and that we must drastically reduce our fossil fuel consumption?

That would be most of us.

And how many of us have drastically reduced our fossil fuel consumption?

Not so many of us.

Mostly, our actions proclaim “We’ll cut back our fossil fuel use when everybody else does … or when the government forces us … or when hell freezes over – whichever comes last!”

Physicist and climatologist Peter Kalmus found the gulf between his beliefs and his lifestyle to be deeply unsatisfying, and he set out to heal that rift.

The result, he says, has been a dramatically richer life for him and his family.

His book Being The Change (New Society Publishers, 2017) outlines the ‘why’ and ‘how’ of his family’s reduction of their fossil fuel consumption by 90% in just a few years. His discussion ranges from climate science to economics, from bicycling to beekeeping, from community networks to meditation, in a deeply inspiring narrative.

Waves of gravity

Kalmus didn’t begin his scientific career in climatology. With a PhD in astrophysics, his speciality was gravitational waves and his day job was working through the data that would, in 2016, confirm Einstein’s prediction of gravitational waves.

But he was also learning about the onrushing catastrophe of climate change, and as a young parent he was deeply worried for the world his children would inherit. Motivated by a desire to work on problems closer to home, he switched his professional focus, taking a new job at NASA studying the role of clouds in global warming.

Kalmus describes Being the Change as a book for the head, the hands and the heart. Wearing his scientist hat, he lucidly lays out the science of climate change. These chapters don’t require more than a high-school science background to understand, but even those who have read many books and articles on the subject are likely to learn something. For those who have read little or nothing on this subject, a good beginning would be to read Kalmus’ chapters on climate science three or four times over – he packs a lot of information into 50 pages.

His sobering conclusion is that we have already stalled too long to have any reasonable chance of keeping global warming below 2°C. Within two or three decades, the mean global temperature will be higher than in any record-warmth year in human experience so far. That new climate era will last centuries, challenging the resiliency of not only human civilization but global biodiversity.

The key uncertainty, he says, is the temperature at which global warming will peak. None of us alive today will be here to experience that peak, but our actions this generation will have a major influence on that peak. A higher peak will cause a spike in the rate of species extinctions, and if and when global warming slows or stops, it will take far longer for biodiversity to recover.

“A good overarching goal for today’s civilization would be to minimize global warming and its concomitant biodiversity loss for the sake of the next few hundred thousand human generations.” (Being the Change, page 69)

Fear of not flying

Climate science gives us clear warning of the disaster we are bequeathing our descendants if we don’t change our way of life, fast. Kalmus concludes, “it’s critical we begin saying that burning fossil fuels is causing real harm and needs to stop. It’s even more important to begin living this message.” (Being the Change, page 120 – italics mine)

A second major focus of the book is “hands-on” – the many ways people can change their own lives to join the movement away from fossil fuels. Kalmus relates his personal experiences here, but he also provides valuable suggestions to help others estimate their consumption of fossil fuels and reduce that consumption in meaningful ways.

Kalmus found that one category of fossil fuel consumption outweighed all others in his life: long-distance travel by air. Much of this consumption happened in traveling to distant conferences where delegates would warn of the dangers of climate change. Kalmus’ decision to stop taking these flights led to a more satisfying life, he says – though this was a rejection of one of the signature privileges of a global elite.

“The act of flying is an exercise of privilege. Globally, only about 5% of humans have ever flown.” (Being the Change, page 151)

Even the average American spends relatively little time in the air. Kalmus writes that “The average American emits about 1,000 kg CO2 per year from flying, which is roughly equivalent to one 4,000-mile round-trip between Los Angeles and Chicago.” But in 2010, Kalmus’ carbon emissions due to flying were 16 times that average – and so it was obvious where he had to make the first change to align his lifestyle with his knowledge.

For the average American, Kalmus says, the “largest climate impact is from driving.” He largely eliminated those CO2 emissions from his life too, through routine bicycling, driving a car that he converted to run on used vegetable oil, and taking a bus or trains for occasional long-distance trips.

Each person’s CO2 emission profile, and therefore their opportunities for emission reductions, will be different.

But Kalmus hopes others will share his experience in one key respect – a greater peace with their own lives and their own surroundings.

“I think most people are afraid of a low-energy lifestyle because we equate quality of life with quantity of energy use,” he says. “My experience has been the opposite: low-energy living is more fun and satisfying.”

Reading about his new-found love of gardening and beekeeping, and the strength of the local community bonds he and his family have developed, it’s easy to understand the richness of this low-energy lifestyle.

He also makes clear that he doesn’t believe that purely individual actions are sufficient to halt the fossil-fuel juggernaut. In the realm of public policy, he pens an excellent advocacy for his preferred fiscal approach to reducing national and international CO2 emissions – Carbon Fee And Dividend (CFAD). He also discusses his work with one group working on the CFAD option, the Citizens’ Climate Lobby.

Finding a lifestyle that matches his principles brings joy and a significant measure of peace of mind. At the same time, finding peace of mind is key in giving him the energy to embark on all those personal changes. That brings us to a third major focus of Being the Change: meditation.

“As part of my daily work, I look directly at the truth of global warming, and what it’s doing to the inhabitants of the Earth. Meditation gives me the strength and the courage to keep interacting with this truth, as it is – not only to cope, but to be happy and as effective as possible in enacting positive change.” (Being the Change, page 203)

As one who has never been attracted to the practice of meditation, Kalmus’ story here left me with mixed feelings. On the one hand, his discussions of dissolving the ego and escaping all wants were, for this reader, just about the only parts of the book that weren’t wholly convincing. On the other hand his life story so far is truly moving, and if he says meditation has been central to that journey then I can only celebrate the strength and peace that meditation gives him. More than that, his book has made me ask whether I want to introduce meditation into my own life in a concerted way; better late, perhaps, than never.

Science and love

Peter Kalmus has written a profound book about the science of global warming, and a profound book about love:

“These two seemingly disparate things – reducing my own fossil fuel use and increasing my ability to love – are actually intimately interconnected.”

In the process he grapples with three of the most troublesome questions facing the environmental movement. Can we convince people it’s essential to eliminate fossil fuel use, when our own lifestyles say that fossil fuel use is no problem? Can we convince people that a high-energy lifestyle is unnecessary and destructive, when we act as if our lives depend on that lifestyle? Can we be happily productive agents of change, while we are caught up in the high-energy whirl of consumptive capitalism? It’s hard to answer those questions except with “No, no and no.” And yet Kalmus’ personal message is deeply positive and deeply hopeful:

“On my own path, as I continue to reduce, I’m actually experiencing increasing abundance. It’s a good path.”
