This is your mother Earth speaking.

Hello, this is mother Earth speaking.

Look, I’m sorry but we really need to talk. This has gone on long enough. I thought I wouldn’t come to this. But you leave me no choice. You’re one of my three dearest children. I know I gave birth to you all and everything…

But you’ve been living under my roof for tens of thousands of years now… and you still haven’t moved out yet! Your father isn’t around anymore so I’m just going to have to start charging you board and lodgings. You’ve always using up all my oxygen and you never contribute to making any of it! So I’m just going to have to start charging you for it.

It costs money to produce pure oxygen you know! And you keep burning it all! Oxygen does grow on trees you know! But you insist on cutting them all down now, don’t you? What do you have to say for yourself? Well?! So what do you think is going to happen?

Look. I’ve said it before and I’ll say it again. Don’t come crying to me when your room fills up with CO2!

What’s that? You don’t believe me? You still don’t believe in climate change? Just look at your sister’s room! Now tell me… I bet you’d conveniently forgotten about her. No, I didn’t think so.

Venus left her room in one hell of a state when she moved out. And now look at it! Look at it!! It’s a right runaway greenhouse mess now – I’ll never be able to clean it up! There’s acid rain in there and everything! I can’t even touch the floor of her room, it’s so hot. 462°C. What kind of a temperature is that? So let that be a lesson to you!

And what’s going on with your water? You keep pissing in the fresh water! Your father and I have told you time and time again not to do that. And all this time we thought you were toilet trained. But if that weren’t bad enough – you try to hide the evidence by flushing it all with even more fresh water! As if that helps anything!

You sneak about after dark poisoning all of that valuable organic waste with all sorts of horrible drugs. I don’t know where you even get a hold of those chemicals!

And if that weren’t bad enough, then you go out into other people’s backyards, dig everything up trying to look for something to fertilise the plants here with! Didn’t your aunt teach you better than that? Where are your manners? You know you should be going to the toilet directly in the garden. How many times do I have to tell you? Why do you insist on wasting all of our hard-earned nutrients like that? I just don’t understand it. You’ll send us all broke if you keep it up! Don’t make me force you to wear diapers again! Just imagine the look the asteroids would give you…

Do I really have to remind you of your little brother Mars? To this day nothing will grow in his room! To this day!! I thought you would’ve known better. That’s what happens when you don’t take responsibility for your own water usage. There’s barely a drop in the whole room now! Nothing will grow there anymore — and I do mean nothing.

I thought after your little NASA moon escapade over the weekend that you’d have a little more respect for your own mother, after you saw first hand how hard it is to live in outer space on your own. I thought you’d begin to appreciate exactly how hard it is to make it by yourselves. But no. Do you think it ever becomes ‘easy’, to live in outer space? I can assure you it’s not! Not even for me. And I’ve had 5 billion years of practice.

There are bills to pay. Laws. Regulations. Responsibility. Right now you just don’t have enough responsibility!

I told your father I didn’t like you hanging around that crowd of friends at school! You’ve picked up all these bad habits from them haven’t you? It’s not like you don’t have your own income either. Is it? You’ve got more than enough money coming in. But you waste it all on bullshit material things. Things you don’t need instead of the things that really matter. So how about you helping out your ol’ mum from time to time?

What a monkey space mission!

—

They’re planning on sending monkeys into space in 2017…

Please, don’t send monkeys into space to try and ‘fix’ everything. If you do, you’re only abusing and exploiting monkeys for humanity’s benefit.

Where is the ‘reward’ for the monkeys? What’s in it for them? Have you asked them whether they know how many banana trees grow on the planet Mars or in Space? Because I’m sure if you could communicate that to them, they would jump on your face and start scratching at your eyeballs in order not to go.

See, this might have been okay in the 60s. But now we know better.

Fellow humans, the ‘answers’ (and by that I mean a technical solution to all the problems we face down here on Earth) won’t be found in exploring Mars. You’re not going to like this, but the answer to our survival is in making less, doing less. Not more. Less. Minimalism. That is the only way we can move forward.

We need to respect animals in order to survive as a species. We ourselves are animals!

So ban the whole darn mission I say. And my message to scientists is: ask yourselves why you are doing research. Are you doing research just to do research or to better humanity? If you’re trying to make us better humans, this is not the way. How does it make us better? How does it make our future better?

 

When is donald trump going to be president?

CORRECT ANSWER: well, assuming he hasn’t been assassinated yet, January, 20th, 2017.

And now that I’ve got you here with my keyword spamming trickery, I’ll spend the rest of this post talking about carbon dioxide with respect to climate change — and how it’s the volume that counts.

I know half of you are interested to know “when donald drumpf is going to be president” (for the right reasons). And half of you are interested to know “when donald trump is going to be president” (for the wrong reasons)1.

Yes. That’s right. This blog partly makes up or all the climate change deniers. And it’s precisely YOU I’m targeting here.

So. I’ve noticed that people always talk of gas emissions in terms of mass, which severely understates the quantity…

Exactly how much space does 1 tonne of CO2 gas occupy? You only need to look at molar volumes of gases:

People talk of gas emissions in terms of mass, which understates the quantity…  But exactly how much space does 1 tonne of CO2 gas occupy? You only need to look at molar volumes of gases:

1 tonne = 1 million grams.
44g of CO2 = 1 mole = 24.5L of gas (at 25ºC and standard atmospheric pressure)
Therefore, just 1 tonne of CO2 gas occupies 557 thousand litres. (= 22.7 kmoles or 557 m3)

Taking the figure above, annual global CO2 emission at 7910 million metric tons (7,910,000,000), multiply that by the volume occupied by one tonne (557,000), and we come up with 4.4 thousand trillion litres of CO2 gas produced every year.

We spew 4,400,000,000,000,000 litres of CO2 into the Earth’s atmosphere every single year.

We do not live in an infinite space, not in area, nor in volume. Yes, gravity sucks back all those CO2 molecules to planet earth. So I take the thickness of the atmosphere, from wikipedia:

I think we as people have forgotten the following important factoids:

50% of the atmosphere by mass is below 5.6 km altitude (18,000 ft).
75% of the atmosphere’s mass is within 11 km of the planetary surface.
90% of the atmosphere is below 16 km (52,000 ft).
99.99997% of the atmosphere is below 100 km (62 mi; 330,000 ft).

And the Earth’s total surface area from another source:

The total area of the Earth is approximately 510 million square kilometres.

My ultra quick calculation of volume of Earth’s atmosphere, up to 100km (yes let’s include all of it) = 51 trillion trillion cubic metres or 51,000 trillion trillion litres. That includes the atmosphere, the stratosphere, the troposphere, the mesosphere -yes, the entire fucking quota.

It appears some people claim that we can produce that much CO2 gas, 4.4 thousand trillion litres every single year, and it no way affects the limited volume of ‘our own’ atmosphere (51,000 trillion trillion litres)! That’s equivalent to an increase of 86 parts per billion CO2 gas every single year.

A few points:

  1. Of course, much of these emmissions are recycled into oxygen by trees and plants during photosynthesis. But while we continue to cut those down that won’t help us with our CO2 problem!!
  2. The upper atmosphere, the stratosphere, is extremely low pressure & doesn’t actually “hold” much gas.
  3. CO2 is 1.5 times denser than air.
  4. Using other estimates of the mass of the Earth’s atmosphere (5 quadrillion metric tonnes) used in the above calculation results in an increase in CO2 concentration of 1.6ppm per year!
  5. The world’s oceans can also dissolve some  CO2, acting like a large reservoir. But here again, there is a limit to how much seawater can take.

Do I even need to elucidate my calculations further? People claim that our  CO2 production has no affect on our precious environment, not even cumulatively! And as an ex-research scientist, that mode of thinking enrages me.

As far as I’m concerned, anyone who thinks that our way of life doesn’t affect the environment (climate included) is an idiot. Sorry, but some people still continue believe that we can spew as much CO2 into the air as we want and it will have no long-term effect on the Earth’s climate. 

You only need to look at exactly how much CO2 is produced by man:

Since 1751 roughly 315 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. Half of these emissions have occurred since the mid 1970s. The 2004 global fossil-fuel CO2 emission estimate, 7910 million metric tons of carbon, represents an all-time high and a 5.4% increase from 2003.

Farming Mars

—

Another one wants to colonise Mars! Sorry, I can’t help myself:

Breakthroughs happen only when we stretch our physical limits

To make Planet Earth survivable, we envision what’s possible on Mars.

The Mars Farm Odyssey is an international consortium of like minds: companies, researchers, NGOs and government groups from the United States to China. We connect bleeding edge technologies and science in Controlled Environment Agriculture to feed a planet of 10 billion Earthlings at home and on Mars.

http://fluxiot.com/marse.io/

Whenever I see people talking about colonising Mars, I just have to speak up. And sorry for the language that is going to come, but I feel very passionate about this.

Dreamers! I think you’ll find that Earth, even in the “semi fucked” state that it’s in, is a far better home for people. Nicer. Easier. Cheaper. Better. Better ROI. Easier for people to adjust to.

Sorry to disappoint you, but there is not enough rocket fuel on this planet for 10 billion people… not only that, but the more people you get there, the more you are going to fuck things here. The fable “the dog and the bone comes to mind”.

And if it did work, if it was self-sufficient on Mars for a few hundred or thousand people, Marslings are only going to be telling Earth people about sustainability. They’d be telling *us* not to fuck our air, water and food supply. They’d be telling us to plant more trees and buy less stuff.

I think we should only go when we can do it sustainably.

Good luck with it, seriously. I wish you good luck. And note that I’m not saying it can’t ever be done. But just because you can do something, doesn’t mean you should.

Take a look at this latest graph.

—

Go on, have the balls to actually look at it:

nsidc_global_area_byyear_b-800x533

See where we are? We’re right at that point where we don’t want to be. That’s where we are. The appropriately red-coloured line that is beneath all the others (well beneath).

Look, I don’t claim to know much about climate science. I know about materials science. But if there’s one thing scientists know how to do, it’s to respect others’ areas of expertise. Especially the expertise of other scientists.

It’s a bit like the song:

“What you don’t know you can feel it somehow” — U2

We know that there are others who are cleverer than us. And we respect that knowledge.

So I admit that I don’t know how the Earth’s climate fully works. But this latest graph worries me. This graph worries me a lot.

Because its pretty darn obvious to anyone what is going on in this graph.

I don’t think the Earth is completely screwed just yet. But if we don’t change NOW, then it will be.

I think the Earth’s climate is remarkly resilient considering all we’ve thrown at it over the last century.

But all I know is, if man thinks he can change local environments —on a global scale mind you— without global consequences, well then he is sorely mistaken.

That is not the way this world works. That is not how any world works.

Because this is the graph of all graphs. This graph should be printed on the insides of all petrol tank lids.

Every time you wish to use your car, you should be thinking of this graph!

Every time you want to fly somewhere, you should be thinking of this graph!

Every time you eat meat, you should be thinking of this graph!

This is the “climate emergency” graph that James Hansen is referring to.

And what do I see? In reality? In reality, I look around today, and I see bugger all people talking about this problem. And yet it is a big problem. A very big problem.

People should be talking about this over their lunch break and their coffee break. And for some reason they’re not. They’re just not.
