2826. "Do We Really Need to Fly?": Meet the Climate Scientists Walking Their Talk

By Dahr Jamail, Truthout, February 1, 2018
Annual flight statistics
Last December, atmospheric scientist Peter Kalmus ruffled some feathers when he called out 25,000 of his colleagues for flying to the American Geophysical Union's Fall Meeting.
Being acutely aware of the worsening impacts from anthropogenic climate disruption (ACD) -- since it was, after all, his job -- Kalmus had already made some dramatic changes in his own life to reflect some of the steps he knew the larger culture needed to take.
In 2010 he quantified his own carbon emissions and realized they were dominated by flying: More than three-quarters of his emissions were from flying alone. So, over the next two years he made an effort to fly less, and began to think of his airplane trips within the context of a warming planet.
"In 2012, I was sitting on a plane -- the last flight I've taken -- and I had this strong, visceral sense that I didn't belong there, that I didn't want to continue being part of the problem," Kalmus told Truthout, speaking for himself (and not on behalf of any institution with which he is affiliated). "Flying felt like a sort of taking from my children. It wasn't guilt; it was clarity."
He has not flown again.

Flying Less

Flying Less, a petition for academics with over 400 signatories, is becoming better known by the day, as is the No-Fly Climate Sci website, where Earth scientists and other academics who don't fly or fly less are joining together to share their ideas.
Dr. Andreas Heinemeyer is a senior researcher and assistant professor at the Stockholm Environment Institute at the University of York, where she works on carbon cycling and ecosystem services in relation to ACD and land use. ​
"We should have curbed greenhouse gas levels about 20 years ago," she explained. "We certainly have created the issue in the first place -- all our wealth is based on this overuse of resources in connection with fossil fuel and land use impacts on rising greenhouse gases."Like Kalmus, her work has impressed upon her the urgency of our global situation. She told Truthout the situation with ACD is "very urgent" and that real changes are long overdue.
In addition to the need for government action, Heinemeyer feels we are all obliged to do something about it.
"This includes assessing where we overuse resources and waste energy and limit this excess behavior," she said. "This requires education but also leadership."
Christoph Küffer is a professor of urban ecology in Zurich, Switzerland, and a member of No-Fly Climate Sci. He studies the ecology of the Anthropocene and ACD's impacts on mountain ecosystems as well as restoring green infrastructure and biodiversity in cities.
"Obviously, [ACD] is a very urgent issue," he told Truthout of his reasons for joining the group. "It affects foremost the weakest, and a small minority of us uses the vast majority of resources."
Kalmus told Truthout he believes ACD is a far more urgent situation than the average person understands. He explained how it is affecting nearly every aspect of life on Earth.
"It threatens our homes, our livelihoods, our food supply, our geopolitical stability," he said. "It's happening faster than we expected. In the scientific community, we've had this unfortunate tendency to underestimate rates of change due to under-modeling complex processes such as permafrost methane release and ice sheet disintegration."
He added that ACD is long-lasting because CO2 will stay in the atmosphere for tens of thousands of years, and the injury to biodiversity will take millions of years to heal.
Kalmus believes it is time for us all to take a step back and think seriously about what we actually need. Do we really need to fly halfway around the world in a matter of hours?
"Or are things like a healthy biosphere, stable climate and reliable food system more important?" he asked. "Is a carbon-rich lifestyle for an elite few worth hundreds of millions of climate refugees tomorrow, and disruption for tens of thousands or even millions of years?"
Kalmus believes that while wind and solar energy are obviously also part of the solution, he does not see the prospect of developing renewables as enough of a fix on its own. Hence, he is taking action to spread consciousness about how we all live.
He told Truthout that his own process of reducing his emissions has been surprisingly fun and satisfying. He wrote about it in his book Being the Change: Live Well and Spark a Climate Revolution.
"At work he studies the physics of clouds in a changing climate, and at home he explores how we can address climate change while living happier, more connected lives," reads his "About the Author" page. "He lives in Altadena, California, a suburb of Los Angeles, with his wife and two children on 1/10th the fossil fuels of the American average. He enjoys orcharding, beekeeping, and backpacking."  
"Can we get by with less electricity?" he asked. "If we cut our use in half in the US, we'd only need to build a quarter as much wind, solar and storage to decarbonize our grid. Is our fast, fossil-fueled lifestyle even that satisfying, or might we be happier if we slowed down a bit?"In our interview, Kalmus said that we all need to be asking ourselves some challenging questions.
Kalmus thinks what is required is a cultural shift to bring about the rapid, large-scale change that is our only hope for some mitigation of the impacts of ACD. In addition to institutional action, that cultural shift will require individuals to push the bounds of what society views as normal.
"We need to get to a point where burning fossil fuel is no longer socially acceptable," he said. "I know we'll get there, I'm pretty sure I'm on the right side of history here, but the question is how long will it take? Time isn't on our side."

Living What They Preach

Küffer, who has managed to go a year without flying, decided to affiliate himself with the No-Fly Climate Sci group because, he says, while humans invented the airplane, the pursuit of "non-flying" is its own form of innovation.
"Innovation happens only if we try, experiment and learn by doing," he said. "There is a belief in our society that we can have everything together, that we can fly as much as we like and have simultaneously all the benefits of non-flying. But there are opportunity costs. My experience is that non-flying brings lots of benefits."
Heinemeyer decided to affiliate herself with the no-fly group because of ACD's impacts on society's underpinning ecosystem services, including food security.
She does not see her efforts to fly less as an inconvenience.
"It might be an inconvenient truth, but it is quite convenient to stop flying … just do it!" she said. "However, I have to admit that there are some downsides and consequences one has to consider: lower international profile (no conferences over the pond), less involvement in conference attendance overall … and potential issues with promotion."
However, Heinemeyer has three children and is working to be truthful with them about ACD issues and the urgency of changing their lifestyle, as well as how to do so.
"I feel that I have to live what I preach," she said.
Kalmus thinks scientists and academics should be taking on the role of "cultural leaders." He points out that Earth scientists, in particular, have front row seats to multiple, connected Earth system catastrophes unfolding in real time, from dying coral reefs to record-breaking wildfires -- and they need to share that perspective with the public.
"We know that this isn't the 'new normal.' It will get steadily worse until we stop burning fossil fuel," he said. "Doesn't this knowledge come with some responsibility? Studying climate change isn't like studying astrophysics: Earth science has revealed a clear and present danger to civilization."
"I don't expect every Earth scientist to do this, but I do hope more start to see it this way, because we need all hands on deck," he said, going on to add that he hopes that as a community, Earth scientists and climate researchers will embrace the seriousness of what their science is telling them. "A good place to start would be to find ways to systematically reduce our flying, like more teleconferencing, more local conferences. Doing this can only enhance our credibility."Kalmus feels he can't separate being a scientist from being a concerned, responsible citizen and father. One way to communicate the urgency of the climate emergency, he says, is to live his life like it's urgent -- to model the transition away from fossil fuels.
Küffer echoes the belief that "walking the talk" should be part of how credibility is evaluated among scientists and academics.
"As environmental scientists we can't call upon the world to stop all CO2 emissions within the coming few decades while we ourselves don't change our habits," he said. "Maintaining credibility of scientific facts, academia and experts has become a key challenge of the sciences in our time."
Reflecting on the kind of science that is needed today, Küffer added, "Flying even affects how we do science."
Heinemeyer wants her colleagues to know that it is indeed possible to fly less, or even to cease flying altogether. Her hope is that her efforts will inspire people. She says she wants to "create a feel for 'it does matter what I do,' because simply put, it does -- but only if enough of us do it!​"
Too often, Heinemeyer said, people in her research area and institute work on the issue but then ignore the fact that they themselves can also be part of the solution. Many of them refuse to change their own emissions practices.
"Justifying flying by doing good is no good per se, mostly just a simple excuse for not trying alternatives," she said. "Certainly flying less, if not stop flying, should be part of any research project."  ​
The scientists behind the no-fly campaigns are not calling for individual change in a vacuum. Kalmus, for example, also points to many ways we can all push for large-scale change, such as voting out those who attack science, and advocating sensible policies such as an annually increasing carbon fee and dividend. However, he also thinks a key tool in the individual toolbox is conspicuous non-consumption: cultural shift through individual change. 
"This isn't a hopeless situation," he said. "Yes, climate change is here, and it's a shame we didn't start dealing with it 10 years ago. I'm not optimistic that we'll keep global mean surface warming below 2 degrees Celsius. But 3 degrees of warming will be much worse than 2 degrees. And 4 degrees of warming will be much, much worse."
There are worst-case warming projections that exceed even 4 degrees Celsius, and there are many factors that will continue to drive warming under the current global economic system. However, Kalmus and his colleagues are working to bring their lives in line with Mahatma Ghandi's code of "being the change" they hope to see in the world. It is a heartfelt and dignified stance in a time of environmental uncertainty, violence and strife.

2825. Air Travel and Climate Change

By Peter Kalmus, Yes Magazine, February 11, 2016




I'm a climate scientist who doesn’t fly. I try to avoid burning fossil fuels, because it’s clear that doing so causes real harm to humans and to nonhumans, today and far into the future. I don’t like harming others, so I don’t fly. Back in 2010, though, I was awash in cognitive dissonance. My awareness of global warming had risen to a fever pitch, but I hadn’t yet made real changes to my daily life. This disconnect made me feel panicked and disempowered.
Then one evening in 2011, I gathered my utility bills and did some Internet research. I looked up the amounts of carbon dioxide emitted by burning a gallon of gasoline and a therm (about 100 cubic feet) of natural gas, I found an estimate for emissions from producing the food for a typical American diet and an estimate for generating a kilowatt-hour of electricity in California, and I averaged the Intergovernmental Panel on Climate Change and Environmental Protection Agency estimates for CO2 emissions per mile from flying. With these data, I made a basic pie chart of my personal greenhouse gas emissions for 2010.
This picture came as a surprise. I’d assumed that electricity and driving were my largest sources of emissions. Instead, it turned out that the 50,000 miles I’d flown that year (two international and half a dozen domestic flights, typical for postdocs in the sciences who are expected to attend conferences and meetings) utterly dominated my emissions.

Hour for hour, there’s no better way to warm the planet than to fly in a plane. If you fly coach from Los Angeles to Paris and back, you’ve just emitted 3 tons of CO2 into the atmosphere, 10 times what an average Kenyan emits in an entire year. Flying first class doubles these numbers.
However, the total climate impact of planes is likely two to three times greater than the impact from the CO2 emissions alone. This is because planes emit mono-nitrogen oxides into the upper troposphere, form contrails, and seed cirrus clouds with aerosols from fuel combustion. These three effects enhance warming in the short term. (Note that the charts in this article exclude these effects.)
Given the high climate impact, why is it that so many environmentalists still choose to fly so much? I know climate activists who fly a hundred thousand miles per year. I know scientists who fly about as much but “just don’t think about it.” I even have a friend who blogged on the importance of bringing reusable water bottles on flights in order to pre-empt the miniature disposable bottles of water the attendants hand out. Although she saved around 0.04 kilograms of CO2 by refusing the disposable bottle, her flight to Asia emitted more than 4,000 kilograms, equivalent to some 100,000 bottles. I suspect that most people simply don’t know the huge impact of their flying—but I also suspect that many of us are addicted to it. We’ve come to see flying as an inalienable right, a benefit of 21st-century living that we take for granted.
The quantitative estimates of my emissions guided me as I set about resolving the dissonance between my principles and my actions. I began to change my daily life. I began to change myself.
My first change was to start bicycling. I began by biking the 6 miles to work, which turned out to be much more fun than driving (and about as fast). It felt like flying. Those extra few pounds melted off. Statistically speaking, I can expect biking to add a year to my life through reduced risk of cardiovascular disease.

Other moves away from fossil fuels turned out to be satisfying as well. I began growing food, first in the backyard and then in the front, and I discovered that homegrown food tastes far better than anything you can buy. I began composting, an honest and philosophical practice. I tried vegetarianism and found that I prefer it to eating meat; I have more energy, and food somehow tastes better. I began keeping bees and chickens, planting fruit trees, rescuing discarded food, reusing greywater, and helping others in my community do the same.
I stopped taking food, water, air, fuel, electricity, clothing, community, and biodiversity for granted. I became grateful for every moment and more aware of how my thoughts and actions in this moment connect to other moments and to other beings. I began to experience that everyday things are miracles: an avocado, a frame of honeycomb crowded with bees, a conversation with my son. Now, I feel more connected to the world around me, and I see that fossil fuels actually stood in the way of realizing those connections. If you take one idea from this article, let it be this: Life without fossil fuels is fun and satisfying, and this is the best reason to change.
But none of these changes had the quantitative impact of quitting flying. By 2013, my annual emissions had fallen well below the global mean.

My wife and I drive 2,000 veggie oil miles to Illinois each year to visit our parents. Along the way, we sleep under the stars in the Utah wilderness. This is adventure travel, the opposite of fast travel, and it has deepened my relationship with my parents. After such a journey, I more easily see how precious my time with them is.I experienced a lot of social pressure to fly, so it took me three years to quit. Not flying for vacations was relatively easy. I live in California, and my wife and I love backpacking. We drive on waste vegetable oil, but even normal cars are better than flying. Four people on a plane have 10 to 20 times the climate impact as those same people driving a 25 to 50 mpg car the same distance.
Not flying is an ongoing challenge as I progress in my scientific career, but I’m finding that I can thrive by doing good work and making the most of regional conferences and teleconferencing. Not flying does hold back my career to some extent, but I accept this, and I expect the social climate to change as more scientists stop flying.

In today’s world, we’re still socially rewarded for burning fossil fuels. We equate frequent flying with success; we rack up our “miles.” This is backward: Burning fossil fuels does real harm to the biosphere, to our children, and to countless generations—and it should, therefore, be regarded as socially unacceptable.
In the post-carbon future, it’s unlikely that there will be commercial plane travel on today’s scale. Biofuel is currently the only petroleum substitute suitable for commercial flight. In practice, this means waste vegetable oil, but there isn’t enough to go around. In 2010, the world produced 216 million gallons of jet fuel per day but only about half as much vegetable oil, much of which is eaten; leftover oil from fryers is already in high demand. This suggests that even if we were to squander our limited biofuel on planes, only the ultra-rich would be able to afford them.
Instead, chances are that we’ll live nearer to our friends and loved ones, and we won’t be expected to travel so far for work. Those both seem like good things to me.
With the world population approaching 8 billion, my reduction obviously can’t solve global warming. But by changing ourselves in more than merely incremental ways, I believe we contribute to opening social and political space for large-scale change. We tell a new story by changing how we live.
