What is the amount of carbon dioxide gas generated by all the cars in the world today?

December 20, 2016 — leslie dean brown

I previously wrote an article which contained a simple calculation to estimate the amount of CO2 emitted by 1 litre of petrol. And it was a fairly popular blog post. From there it was easy to estimate the amount of CO₂ produced by driving on one full tank of petrol.

When one litre of petrol is burned, 2.28kg of CO₂are produced, equivalent to 1268 litres of of CO₂ gas!! Every single 50 litre tank full of petrol will produce over 63,400 litres of CO₂gas (63.4 m³), or a volume of pure CO₂gas equivalent to an imaginary cube with sides 4 metres long.

Now I’m going to calculate how much CO₂ is produced by the fleet of 500-600 million cars worldwide using just one full tank of petrol and compare that figure with the total volume of the Earth’s atmosphere.

600,000,000 x 63,400 = 38,000,000,000,000 litres.

38 trillion litres on just one tank of petrol.

What’s the average annual petrol consumption? Average distance driven per year? Easier to get the stats from elsewhere at this point, more reliable:

Cars – together with power stations- are the main producers of CO2. Today 500 million cars world-wide emit four billion tonnes of CO2 into the atmosphere – around 20 per cent of the total quantity produced by mankind. And the number of cars on the road is growing rapidly – currently twice as fast as the world’s population. Forecasts assume that this number will reach 2 billion world-wide by the year 2030. This will mean that petrol consumption will grow to an estimated 1.3 billion tonnes by 2030. CO₂ emissions from traffic would then increase to more than 7.5 billion tonnes. Source: greenpeace

I’m an ex-scientist. And scientists deal with numbers. It is our job to try and explain very large numbers to people.

I think we’re all very used to hearing the words ‘thousands’, ‘millions’, ‘billions’ and even ‘trillions’.

And we’re not used to measuring the weight of gases. We’re used to seeing their volume. Aren’t we?

So. If that happens, if CO₂ emissions from traffic increase to 7.5 billion tonnes per annum, why, do you know how many litres that is?

I’ll tell you how many litres of CO₂ that is. It’s 3.82 quadrillion, that’s how many litres of CO₂ that is. Per year.

Now, I’m willing to bet that you don’t even know how big one quadrillion is, let alone 3.82 of them. It’s “fucken huge”, that’s how big it is. Just how much bigger is one quadrillion than one billion?

Let’s imagine there were 3.82 quadrillion people scattered throughout the universe… and that there are 7.5 billion people on each planet¹, there would have to be 509 million planets in existence to total 3.82 quadrillion people.

That’s how much CO₂gas cars pump into one of our Earth’s atmospheres every single year.
3.82 quadrillion litres of CO₂.

I was worried back in ’92.

October 10, 2016 — leslie dean brown

Yes I first learned about “global warming” in 1991 or 1992.

I think I must have had a smart teacher for the subject called general studies, because she knew about this new topic and warned all of us. She probably heard all about it at the United Nations Conference on Environment and Development (UNCED) aka the Rio de Janeiro Earth Summit. I could tell she was concerned. I can still remember seeing the worry in her eyes way back then.

Also, like a lot of nerdy sciency kids, I already knew about the atmosphere of other planets (like Venus for example). And so I’ve known for a long time that there isn’t really anything (apart from biodiversity feedback loops) stopping this planet from becoming more like either Mars or Venus.

So I began making lifestyle choices back then, when I was 14 or 15 years old. I chose not to drive. I continued to ride my bicycle. I rode it everywhere. In fact I didn’t learn to drive a car until I was 28 years old. Not until I had to. Not until I needed to deliver a lot of bicycles for my business. But eventually, it all caught up with me again. It slowly dawned upon me that I was falling into the trap of becoming just like everyone else again.

We are supposed to be working for a better future. That is why we all work so hard. But if the future is going to be worse, what’s the point?

So now, after almost a decade of driving around, I’m slowly but surely weening myself off of it again.

Later, when I gratuated, I refused to work for oil companies. I was offered a very highly paid job investigating the steel microstructure of crude oil tankers. I just couldn’t do it. So I went straight back to university and did another 5 years there.

Climate scientists are saying now that we are in a “climate emergency”. Look, the coal industry in Australia is saying there is enough coal reserves to last another 365 years. Well okay. But if other planets are anything to go by, this world’s entire fucking oceans could potentially boil right off and disappear into deep space! Melting icecaps will be the least of our worries. Now, while that scenario is never mentioned by climate scientists, that’s what planetary scientists mean when they talk about “a climate system that is out of control”. Are people starting to get it now?

Now I still don’t think people even today fully realise the implications of climate change, 25 years later.

On creativity. And Space Ace Jase.

What is the strangest thing you have ever heard?

When I was growing up, by far the funniest, most preposterous thing I had ever heard anyone say was this:

“I can kick a soccer ball to China”.

As kids, I can remember us all standing in the middle of the street. And we simply erupted with laughter.

Air, friction, gravity and power aside… it was the silliest thing I had ever heard anyone say. So forever afterwards, he was known in our circle as “Space Ace Jase”.

He had said something that none of us had ever heard before. What he said… he had said the impossible.

Looking back, you have to hand it to this kid – he was certainly creative.

And I can remember wondering, how did he think up such things? Kick a soccer ball to China… that’s ridiculous! Ha ha ha ha ha ha.

But then later in life, we realise we have lost a lot of that creativity we were inherently born with. It has been slowly eroded from us.

We are taught what to say. How to say it. When to say it. Why to say it. Where to say it. Which people to say it to. So we eventually lose that sense of silliness.

I think it’s because people seem to assume you dont need to be ‘clever’ to be creative. It all starts around high school. All the nerdy, intelligent people do maths and science to get a higher tertiary entrance tank score. And science, engineering and maths don’t at first appear to be very creative, do they? They always rank higher than music, literature and art.

I used to get paid quite a bit but I found it all rather boring after several years. So you need to ask yourself: what does compensation matter if you /really/ don’t like doing it?

And then sooner or later we want to get some of that creativity back again…

So how do we become more creative?

I think creativity is simply doing something in some new way with something that has never been done before. Creativity is after all… simply creating something new!

Creativity simply means taking two things that have never been put together and just… whacking them together.

First off, have you noticed that parents often tell their children: “don’t be silly!”? They say something completely new and then they are promptly told it is silly. “Don’t be silly” you hear parents say straight afterwards.

Well I think in order to be creative, you have to be prepared to take risks like that. You have to be prepared to say something wrong. Just like kids. They are always making mistakes, but they are naturally very creative.

For me, being creative, maintaining my creativity —or better yet boosting it— usually means doing something differently. And doing something completely different each and every day.

Going somewhere I have never been. Seeing something I have never seen. Listening to sounds that I have never heard before. Or reading something I have never read before. Even feeling things I have never felt before. I’ll skip the sense of smell just to throw you off my sense-track-pattern.

So my best advice to you, if you want to be more creative, to do that, is to start doing things differently. If you have a choice, choose the option you don’t normally choose. Don’t go to the same old cafe. Don’t walk the same route.

Why do creative careers pay less anyway?

Being creative uses your intelligence in a different way. We should all be paid the same. The same as ‘clever’ people. Because I’ve noticed that clever people can actually be very uncreative. That’s why nerds are drawn to all sorts of comics. Becuase they can’t come up with that shit themselves. Am I right? Of course I’m right.

I am slowly becoming more creative and it has taken about 1-2 years to build that skill. I could argue that there is much more actual work involved in creating one of my illustrations than pressing a button and getting the results from a scientific experiment. What I mean is that there are many more minute decisions that have to be made. I should be getting paid more for illustration. But I get paid much, much less.

Unfortunately the world doesn’t seem to work that way. “Like anyone can be creative.”

I would say that if there is a theoretical basis for undervaluing creatives, it is because to be creative, sometimes you have to be prepared to make mistakes (you can’t please everyone). And people that make mistakes are sometimes not seen as being ‘creative’, they are seen as being ‘wrong’. And being wrong or silly doesn’t pay.

So creatives always get paid less. Or do they? If you think about it, professional actors and musicians are some of the most highly paid people on the planet. I’m talking way, way more than 200k salaries.

Well that’s it from me today,

Take care,

Les.

What’s new with GMO?

September 24, 2016 — leslie dean brown

Today I’m going to do things a bit differently.

I‘d like to encourage my followers to read several articles I just found out about. So here are several interesting pieces of news regarding CRISPR, a new gene-editing technique and a couple of links to the first ever completely synthetic, artificial cell:

Please read all of the above articles and educate yourselves. This isn’t in the mainstream news, but it should be.

I should probably state here that I don’t even pretend to know about genetics. I’m not a geneticist, I studied Materials Science.

All I do know is that nature has laws and you cannot break those laws. Bacterial diseases are lifeorms too and they are just as robust and ‘innovative’ as even the cleverest of humans.

I think that scientists often tend to overestimate their own intelligence level, and at the same time, underestimate the resourcefulness of nature itself. I don’t think we can ever fully predict the “revenge effect”. But it is there. The risk is always there.

I’m sure the field of genetics is really, really advanced by now. I’m not saying that it’s not. But the big worry for me is just that— as science becomes more and more and more specialised, people get ‘cleverer’ but they don’t always become ‘wiser’. So to put that another way, the greatest geneticist minds may claim to know all about genes, and they might even be right, but then they cannot also be the greatest experts in ecosystems. The fields of science are that big today that no one can know everything. It’s impossible! That’s the big worry.

“I don’t think it represents the creation of an artificial life form,” said biomedical engineer James Collins at Boston University. “I view this as an organism with a synthetic genome, not as a synthetic organism. It is tough to draw where the line is.” [source]

Development is not progress

September 20, 2016 — leslie dean brown

I believe we cannot save the world by simply buying things all the time.

Illustration by Leslie Dean Brown. © 2015. All rights reserved.

Even if we all bought 100% eco things 100% of the time instead of the plastic crap that everyone buys today, they are still ultimately things and it will mean that the demand for timber and other eco fibres will go up further, leading to further deforestation elsewhere (more plantations of whatever crop, be it corn for renewable plastic, bamboo or hemp for fibres, etc).

Personally I think the only real ‘solution’ for the entire human civilisation is … to do nothing. And by that I don’t mean “don’t change”. I literally mean: do nothing. For people to simply work less. Work a four day week. Work a four hour week.

We should be more like the Aborigines! We should look up to the Aborigines! The original (and best) custodians of this land.

More sleep and more meditation. That’s the only hope for humanity, for people to be more mindful. And that is the best that I can think of (after several years of thinking I might add).

And I can tell you first hand that it’s very hard to live with less, because we have all been brainwashed with “more more more”.

Of course it’s a huge problem because half the global economy is based on blatant overconsumption. I think one of the best things I ever did was to live in Spain — it taught me to be happier with much less.

I’m not saying we shouldn’t all try to be more eco, but what I am promoting these days is simply minimalism. So I would rather buy a wooden broom than have a vacuum cleaner (for example). Because I see the broom as being much less wasteful over the long term.

Unfortunately, when you begin to look at where all of our starting chemicals come from, the industrial processes used to get them, and where everything else is mined from, you realise how big the problem is.

People don’t want mines in their own backyard. And so the ONLY other place to get them is the natural spaces that are left. That is a very big problem. If only because “accidents happen”.

From my point of view as a former materials scientist, I find that life is so special, we should be fighting for every shred of biodiversity on this planet. We couldn’t even hope to artificially make anything like near as complicated as a fly or a worm from first principles using artificial methods (without cheating using genetic engineering etc).
