“Why did climate scientists emit 30,000 tonnes of CO2 this weekend?”

Guest rebuttal by David Middleton

Q. Why did climate scientists emit 30,000 tonnes of CO2 this weekend? 

A. To get to New Orleans to attend the AGU’s Fall Meeting.

From the No-fly-climate-science Guy…


This weekend, 25,000 Earth, Sun, and planetary scientists from across the US and abroad flew to New Orleans for the annual American Geophysical Union’s Fall Meeting. These scientists study the impact global warming is having on Earth. Unfortunately, their air travel to and from the meeting will contribute to that warming by emitting around 30,000 tonnes of CO2.

As an Earth scientist and AGU member myself, I know the importance of their work. Still, there’s something wrong with this picture. As scientists, our work informs us – with dreadful clarity and urgency – that burning fossil fuel is destroying the life support systems on our planet. There’s already more than enough science to know we need to stop. Yet most scientists burn more than the average American, simply because they fly more.

Few people know how harmful it is to fly in planes, including scientists. In 2010, I sat down and estimated my climate emissions. It turns out that, hour for hour, there’s no better way to warm the planet than to fly. I’d flown 50,000 miles during the year, mostly to scientific meetings. Those flights accounted for 3/4 of my annual emissions. Over the next two years, I gradually decreased my flying.

Eventually, there came a day when I was on the runway about to take off and felt an overwhelming desire not to be on the plane. I saw too clearly the harm it was doing to the world’s children, to all the beings on our planet. I haven’t flown since 2012, nor have I wanted to.


In becoming scientists, we didn’t sign up to burn less fossil fuel or to be activists. But in the case of Earth science, we have front row seats to an unfolding catastrophe. Because of this, the public takes our temperature: if the experts don’t seem worried, how bad can it be?


I’m not alone. Over 400 academics have signed a petition at flyingless.org, and a few Earth scientists have joined me in telling their stories at noflyclimatesci.org.


Like academics, climate activists also tend to fly a lot.


Burning fossil fuel causes real harm, and will become socially unacceptable sooner or later.

The Grauniad

Do scientists fly more than the “average American”?  I haven’t see any evidence that scientists fly more frequently than other business professionals.

U.S. Business Travel

 Americans make more than 405 million long-distance business trips per year, accounting for 16% of all long-distance travel (see Box A), according to a preliminary analysis of the National Household Travel Survey (NHTS). Conducted from 2001 to 2002, the NHTS asked 60,000 people in 26,000 U.S. households about all trips they took in a given travel period and looked at the characteristics of those travelers and trips. This report examines early NHTS findings on domestic business trips to destinations at least 50 miles from home.


Contrary to the stereotypical image of the business traveler heading off to catch a cross-country flight, the majority of long-distance business trips in the United States are taken to destinations within 250 miles of home and are by automobile. Nearly three-fourths (74%) are less than 250 miles from the point of departure and most of those are within 100 miles. Trips of over 1,000 miles account for only about 7% of all business trips. (See Figure 1).

Still, at 123 miles, the median one-way distance for business trips is greater than that for trips with other purposes. By comparison, the median distance for pleasure travel is 114 miles and for personal or family business trips the median distance is 103 miles. Long-distance commuting trips have a median distance of 69 miles.

The personal vehicle is the dominant travel mode for business travel, comprising 81% of all trips. Air travel accounts for about 16% of all business trips. The use of the two primary modes shifts, however, as trip distance gets longer. Almost all shorter trips are by personal vehicle—97% of 50 to 99 mile trips and nearly 94% of 100 to 249 mile trips. In the 250- to 499-mile range, the personal vehicle’s share of trips declines to 67%, while the airplane accounts for 31% of the trips.

Only after the 500-mile mark does the car give way to the airplane as the dominant mode of business travel. For trips 500 to 749 miles in length, air captures 64%, compared to 33% by personal vehicle. Of business trips between 750 and 1,500 miles, air captures almost 85%, and of trips more than 1,500 miles in distance, a full 90% are made by air. Accordingly, this yields a median trip distance for business travel by car of 102 miles, but one of 816 miles for business travel by air.


Because the majority of business trips are less than 250 miles in length, it is not surprising that 84% of business trips (341 million business trips) do not cross census region boundaries1 (Figure 2).

The origins and destinations of the 64 million inter-regional trips are not evenly distributed. The West attracts 7.4 million more inbound business trips than it sends to other regions. The South, on the other hand, has 7.7 million fewer inbound business trips than outbound. There is no statistically detectable difference between the inbound and outbound flows2 in the Northeast and Midwest. The South is the largest destination for outbound business trips from each region. Also, the South is the largest generator of inbound business trips to each of the other regions.


The typical business traveler is likely to be male; work in a professional, managerial, or technical position; be 30 to 49 years old; and have an income well above the population average.

Men account for more than three-fourths (77%) of business trips. This compares to nonbusiness travel where men take 54% of the trips and women 46%.

Those who consider their occupation to be professional, managerial, or technical account for over half (53%) of all business trips. This occupational category represents only about 40% of the general population. Sales or service workers account for the next largest share of business trips, 28%. On the other hand, clerical/administrative workers account for less than 4% of business trips even though they represent almost 12% of the population.

About 55% of all business trips are made by individuals aged 30 to 49. Those in their thirties take 28% of the trips while comprising 16% of the population. Those in their forties take 27% of the trips while comprising 15% of the population. The percentage of trips represented by those in their fifties drops markedly, with only 18% of business trips represented by this age group. Overall, this age group accounts for about 11% of the population. The youngest and oldest groups of adult business travelers, 18 to 29 and 60+ years old, represent about 16% and 10% of business trips, respectively.

Business trips are generally made by those with household incomes that exceed the national average, which is about $47,500, according to the Bureau of Labor Statistics. Although 12% of households have annual incomes of $100,000 or more, the NHTS survey found that this income group accounts for over one-fourth (27%) of business trips. Another 18% of trips are made by those with household incomes between $75,000 and $99,000. There are relatively few low-income business travelers. Although 21% of households have incomes of $25,000 or less, only 6% of the business trips are made by that income group.



I suppose academic and government scientists might take more long flights to conferences, while most business flights are relatively short-distance.

I tend to fly a lot, between Dallas and Houston… So do a lot of other people.  It’s probably Southwest Airlines’ most “popular” route.  While I don’t personally know every geoscientist who flies this route, I rarely see any that I know on the same flight with me.  Most of the business travelers are wearing suits or at least jackets and ties… making it unlikely that they are geologists or geophysicists.  My SWAG is that most of them are sales people, lawyers, bankers and other finance people.

My other option is to drive my Jeep between Dallas and Houston; which I do more often than I fly.  I’m going to take another SWAG and say that my Jeep has a bigger carbon footprint than my seat on a SWA Boeing 737.

According to the ICAO calculator, each of my SWA round trips puts 260 lbs of CO2 in the atmosphere.  The EPA says that burning gasoline emits 8,887 grams CO2/ gallon, about 20 lbs./gallon.  It’s about a 500 mile round trip and my Jeep gets about 18 miles per gallon.  I burn about 28 gallons of gasoline on each round trip.  This works out to 556 lbs. CO2. So, if I cared about reducing my carbon footprint, I would fly rather than drive.

As scientists, our work informs us – with dreadful clarity and urgency – that burning fossil fuel is destroying the life support systems on our planet.

–Dr. Peter Kalmus

Dr. Kalmus is a physicist who “uses satellite data, in situ data, and models to study the rapidly changing Earth, with a focus on boundary layer clouds.” So, I guess he could come to the bizarre conclusion “that burning fossil fuel is destroying the life support systems on our planet.”

I recently ran across a survey of scientists (ca 2006) with real jobs and it tells a different story.


Global Climate Change Survey
Bob Shoup, AAPG Climate Committee

AAPG does recognize that pollution from fossil fuels is harmful to the environment. We also acknowledge that high levels of atmospheric CO2 could impact global temperatures. As such, we continue to advocate and support voluntary actions that stimulate the use of clean energy technologies and reduction of fossil fuel emissions.

It must be noted, however, that the world is dependent on fossil fuels to meet its growing energy demand, and will remain so for many decades. We recognize that we are thus conflicted in how we are perceived in this debate. That perception of conflict does not mitigate, however, the very compelling reality that it is unreasonable to ask society to give up its economic prosperity to mitigate increased levels of CO2.

The climate debate is far from over and must be discussed and further debated. AAPG calls on both sides of the issue of anthropogenic global warming to conduct this debate in a more professional manner than has been done so in the past. As a result of the politicization of AGW, data manipulation, alarmism, indoctrination, exaggeration, name-calling, and extortion, have all entered into; and influenced the tone of the debate. These have no place in science, and the professional community must stand together to condemn these unprofessional and unethical behaviors.


Global Climate Change Survey

Bob Shoup, AAPG Climate Committee

While “pollution from fossil fuels is [somewhat] harmful to the environment,” the benefits fossil fuels have provided to human well-being far outweigh any negative effects from the pollution.

I applaud Dr. Kalmus for having the courage to “walk the walk.” However, he and his 400 fellow No-fly-climate-science Guys & Gals, would be better off flying to important conferences and meetings.  If Dr. Kalmus’ work at JPL and the AGU Fall Meeting are integral to saving the planet from Gorebal Warming, he shouldn’t be wasting time by taking the train instead of flying.

Speaking of saving the planet (warning: lots of F-bombs)…

I just can’t get enough of this George Carlin sketch!

“However, he and his 400 fellow No-fly-climate-science Guys & Gals, would be better off flying to important conferences and meetings”

David, I completely disagree with you on this. Any way you slice it, air travel creates pollution. Whether or not it contributes to global warming, and whether or not global warming is good or bad, it’s still pollution. There’s no need for most of these conferences and meetings to be held in-person. With today’s internet technology, video conferencing can and should replace most in-person conferences and meetings. Plus the amount of man-hours wasted in travel time could definitely be better used.

Aircraft exhaust contains a number of things smoke, unburnt hydrocarbon fuel, oxides of nitrogen, oxides of carbon and biological material picked up from the atmosphere and combusted.

If you are into conspiracy theories the last part is the most significant

Now if you want the funny for the day

A 2016 study surveying 77 atmospheric scientists concluded that “76 out of 77 (98.7%) of scientists that took part in this study said there was no evidence of a [secret large-scale atmospheric program (SLAP)]

So 97% Climate Science consensus just beats a conspiracy theory and we all know abuse of statistics in Climate Science is mandatory 🙂

ldb: None of those pollutants do much for global warming. In almost two decades of being concerned with combustion products from fuel combustion (CI engines) I’ve never seen anyone concerned about combusted biological materials picked up from the air and they would be at theoretically higher concentrations.

Even ignoring that, Tom, I think what the author was getting at is that if you don’t attend the meetings, you cannot influence policy.

Yes, it would be best if no one went to the meetings and it’s all done electronically. Cheaper, less waste, more accessible. However, if you go and others don’t, you have more influence and power. Therefore, everyone who wants to influence the results has to go to the meeting. It’s a Nash equilibrium.

Very interesting. As in Russell Crowe?
Its another one of those paradoxes screwing humans over. Like – the only way to rapidly reduce CO2 emissions is to shut down industry but if you do that you get even more warming through reduced aerosols because it is a much faster acting effect.
Oh well, what are you doing for christmas?

Nah, Tony. That’s a no-win situation, aka a catch-22 or Kobayashi Maru.

We used to have a humorous anecdote between MIT and Harvard (just down the street from each other):

At Harvard they teach you less and less information about more and more subjects until you know nothing about everything.
At MIT they teach us more and more information about less and less subjects until you know everything about nothing.

global cooling. Is the current warming trend more of a crisis than the cooling trend of
1940 – 1975?

though not as bad as typical warmist survey – such as the survey showing nearly 90% of americans supporting regulating co2 with the leading question “should the US regulate the pollution that causes global warming?”
I will add that skeptical science was promoting the survey as valid, yet when I pointed out the question was a leading question, the Sk S crowd went wacko defending it

In the Sks survey, they are slanting the results by first calling CO2 pollution (that’s begging the question) and by declaring that it causes global warming (yet to be proven).
In this survey they are asking whether one temperature trend is more of a crisis than the previous temperature trend. Huge difference.

While some comments note the motivation for individual scientists to participate in such conferences that are not strictly science oriented, it should be noted the main motivation behind these large conferences is to provide revenue to the sponsoring organizations. The AGU, AMS, and AAAS generate large amounts of cash with these events. If forced to convert to teleconferencing they would not be able to charge the high per person fee nor get sweatheart treatment from hotels and conference centers. After all an entire laboratory could sit in on many talks while paying for only one connection. Ending such in-person conferences would hit these organizations in the pocket book.

All of these meetings can be held over the Internet so such travel is no longer necessary. If one feels that the use of fossil fuels is bad then stop making use of all goods and services that make use of fossil fuels. It is your money that keeps the fossii fuel companies in business. So no longer make use of computer related devices, wear clothes, eat store bought foods, go inside of most buildings, or walk on surfaces made of asphault, concrete, wood, or synthetic material because they all involve the use of fossil fuels. Everytime you brethe out you add so called greenhouse gases to the atmosphere. Stop it!

December 12, 2017 1:05 pm

I find the whole carbon (dioxide) footprint due to flying somewhere ridiculous. When you buy an airline ticket, your are getting a seat on a plane that is going to fly from A to B whether you are on it or not. If you don’t buy a ticket someone else will likely be in the seat you didn’t take – airlines have been very good at filling their planes for years. So your not flying is likely to reduce aircraft emissions by about zero.

Of course this does not apply to the super rich and famous who wouldn’t be caught dead on a commercial flight and travel by private jet. Their CO2 footprints are far larger than even the most frequent business travelers who fly commercial.

You will of course not get frequent flyer miles so you’ll miss out on a chance to have your employer pay for the accumulation of enough miles to take your family on a nice vacation to Hawaii every few years. Something I suspect even the most environmentally conscious scientists may take advantage of.

Airlines are good at filling seats because they have a lot of planes of varying size.
If fewer people book that seat in advance, the airlines my schedule a smaller plane to fly that route. Or they may adjust the schedule so that 4 planes per day fly that route instead of 5.

“As scientists, our work informs us – with dreadful clarity and urgency – that burning fossil fuel is destroying the life support systems on our planet.”

If I had a dime for every time a statement like that was made, I would be rich. If I had a dime for every time a statement like that was made, but no evidence was sited or reason was given for such clarity and urgency – I would be twice as rich!

and i keep seeing stuff like this… The EPA says that burning gasoline emits 8,887 grams CO2/ gallon, about 20 lbs./gallon.
a gallon of fuel doesnt weight 20lbs does it?
how can what it generates be more than what the original liquid was?
i didnt do chem at school but for the life of me i cant see how output can weigh more than input especially as a damned gas????

It’s models isn’t it.

He means models doesn’t he.

The “dreadful clarity” comes out of a failed model ensemble doesn’t it.

Yes, cephus, it must be models, but I find it hard to believe that even the models are projecting the destruction of the “life support systems of the planet”! I am not sure how anyone can be taken the least bit seriously after making a statement that is so threatening and so completely unsupported.

CO2 is becoming like ‘cake’ to Kevin Hart’s character in the new Jumanji Movie:

If only all catastrophic climate change “believers” would stay at home, turn down the heating, turn off the TV and the Internet, the world would be a better place.

The word “hypocrite” comes to mind. Not in common understanding of the word, “Do as I say, not as I do.”.
I smoke smoke. I told my kids not to smoke. The common understanding would say I’m a “hypocrite”.
But I never pretended I didn’t smoke. I warned them. I never held up a false face before them. (The Greek word the English word “hypocrite” refers to the mask held up by actors in Greek plays so the audience would know what emotion they intended to portray. (Some old movies still open with a picture of the happy and sad mask.))
If I had told my kids not to smoke and then pretended I didn’t smoke, then I’d be a hypocrite.
These people are hypocrites. In every sense of the word.

Pet peeve: People writing C02 (C zero 2) instead of CO2 (C Oh 2).

Post title: “Why did climate scientists emit 30,000 tonnes of C zero 2 this weekend?”

Is this a trick question?

Why? Because they’re ignorant useful tools in helping spread atmospheric fertilizer to help feed everybody on the planet. For this reason, and this reason alone, I can support their frivolity.
