Take a look at this latest graph.

December 7, 2016 — leslie dean brown

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.

My best case yet for conserving biodiversity.

November 30, 2016 — leslie dean brown

Scientists are time-travellers, who can glimpse ~100 years into the future. When I think of the “the future”, here is what I ‘see’:
  • I don’t see ‘manmade’ things flying everywhere; I see ‘birds’ and ‘insects’… behaving like drones. Or rather, I see drones –robots– acting like birds, fish and insects. A form of synthetic nature. Robots. Nanobots.
  • I see a completely flat biodegradable pizza box that is able to reheat your pizza… at the push of a button… biodegradable battery included. Biodegradable materials.
  • I see flexible circuit boards. Biodegradable/compostable circuit boards, adhesives and elastomers. Ones that feed nutrients into the soil rather than leaching out toxic chemicals. Compostable materials.
  • I see homogenous materials exhibiting different physical and chemical properties at each end… or wherever else you wanted. Surfaces that change colour, texture, friction coefficient, refractive index, magnetic susceptibility or any one of —or combination of— any one of thousands of desired properties… inside or outside of them… like a television screen… except displaying an array –a matrix– of different properties. Metamaterials.
  • I see changes in materials’ physical, mechanical or chemical properties… triggered in response to… other changes… such as temperature, composition, acidity. Dynamic materials.
  • I see tyre compounds that become ‘grippier’ or ‘grow’ additional/deeper tyre tread patterns in the wet… according to the conditions. Responsive materials.
  • I see trees… by the side of road… that automatically display the speed limit… and any other desired road signals… with reflective bark… again… according to the conditions. Adaptive materials.
  • I see semi-organic ‘tentacles’ mounted on aircraft carriers… that can ‘catch’ helicopters and other flying craft… in mid flight. Organic materials.
  • I see termites… genetically reprogrammed… to make skyscrapers out of biodegradable ‘cement’. Self-organising materials,
  • I see buildings that simply… build themselves. Self-generating and self-regenerating materials.
  • I see computers that never need new hardware. Computers that truly ‘adapt’ and ‘learn’. Light-based computers. Organic computers. Really advanced, biological computers.
  • I see genetically engineered bacteria that can extract any elements we wish, from landfill.

All these devices are not only possible –100% scientifically feasible– but even probable. Believe me. You ain’t seen nothin’ yet. Of what technology can deliver.

These ‘inventions’ do not break any laws of science. Far from it. They’re already in existence. And this is the potential I see whenever I look at animals and plants and think about them in terms of their material properties.

Everywhere I look, I see nano-materials that humans simply cannot yet compete with. We are not even in the race, the same league, let alone the same competition as nature.

I see people mixing cement today, smelting and forging steel —still— in the year 2016. And it’s a crude process at its very best; always from the “top down” scale direction, never from the “bottom up”.

Eventually though, as we play the game of “catch up” —by studying and ultimately copying nature— there’s really only ONE thing that stands in the way of scientists, engineers and designers creating, reverse-engineering these things (and more) in the future.

And that’s the threat of extinction. Because all of the above hypothetical inventions share one thing in common: they’re based on materials that are already found in living systems.


Nature is good for our emotional, psychological and physiological wellbeing. Nature is ‘natural’. Nature is ‘pretty’. Nature is ‘beautiful’. And all species have an equal ‘right’ to survival as any other. Isn’t that enough reason to want to protect it?

We humans cannot recreate a forest, a mountain view, a lake, a river or a natural shoreline. And where do many of us like to go for recreation, if we want to truly rejuvenate? Where do we go on holidays? We go to nature. Or even to some virtual ‘approximation’ of it.

Shouldn’t that be enough to save it? Apparently not. So if you want the cold, hard ‘justification’, the main scientific reason, to fight for all forms of biodiversity –the fundamental reason that all accountants, long-term financial planners and investors are really looking for– then here it is:

Simply put: if we scientists don’t have enough living systems –biodiversity– available to effectively be able to research, to study, then not only will the amazing device described above never get built by us, but we’ll likely find it harder and harder to survive the further we get into the future1. Indeed, we may find that at one point, it doesn’t get any easier at all — rather, that it gets harder. Much harder.

Yes we NEED different species. Not just for our own immediate survival (in terms of oxygen/air, clean/filtered water, fresh food). We need different species in order to be able to study them well into the future. We need as many different species as possible. We need species with even the most subtle differences, –in fact, especially the ones with the most subtle differences– to be able to eliminate the bane of every single well-trained scientist: variables. Or rather, more than one variable.

Suppose there were only two animal species in existence: an elephant and a stingray. Suppose. Just the two (never mind what they eat for now). Then it would be very hard to work out which genes cause which morphology in each animal. How do we know which gene causes the trunk and which forms the tusk? How do we know which gene forms the stingray’s tail or its spine? And so on. For every new variable in each animal, it becomes ever harder to distinguish between the genes, which genes cause which traits.

With insufficient samples, science is nothing. What about with no samples at all? How much is science worth then, with no samples?

Furthermore, the exact same protein may lead to different morpholgy when it is located in a different part of the genetic sequence, as in a different species. It’s not entirely predictable.

That’s why genetic engineers are never as clever as they think they are. That’s why there’s this whole “anti GMO” movement (well that’s one reason). Because if we knew EXACTLY what we doing, why, we’d be able to create practically anything we wanted. Already. Now. Today. Besides, some genes are redundant.

Do we know which ones? Do we know why? Do we know where? Do we know how? Do we know, for each and every single one of the estimated 1 trillion fast-disappearing species on planet Earth? I don’t think so. Genetics is not my area. Even so, I don’t think there are enough scientists alive today to know and study all of that genetic information; there is too much information out there. I don’t know. I know about materials science, not biology. I do know that biological materials are several orders of magnitude more complex than purely synthetic, manmade materials. [Read more…]

Wisdom

September 11, 2016 — leslie dean brown

“The tree breathes what we exhale. When the tree exhales, we need what the tree exhales. So. We have a common destiny with the tree.” — Oren R. Lyons 

Wiser words have never been spoken. I think we need to really start listening to these people. Science will never be able to invent a more beautiful, efficient or sustainable oxygen factory… as the humble tree. That’s why I agree that we should all plant more trees (and also avoid cutting down any to begin with). It was also a reccommendation of the book “small is beautiful”.

If we were living on Mars…

September 5, 2016 — leslie dean brown

I’d like to remind people of two things:

1Would Mars colonists be doing things the same way that we are here and now? For example, would they be mowing grass if and when they manage to get it to grow under their domed little base stations?

I think not. Not very sustainable, is it? Using up petrol and mower parts all for what? To keep the grass shorter and produce less oxygen? (at least that’s the excuse I give now for only mowing 9/10 of our backyard rather than the whole darn lot) Why do we cut grass anyway? Those are the sorts of questions humanity ought to be asking itself.

2Just imagine if all of 7.4 billion of us humans were *already* living on Mars (indoors) and we just happened to “find” Earth in the ‘state’ that it is in now, except with no people…

Do you think we would stay on the planet Mars? Where do you think we would move to? That’s right, we’d move right over to the planet Earth, where you can breathe freely… where the essential things like oxygen and rain are still free… where dirt is *almost* free (right now it costs $10,000,000 to launch a tonne of dirt into outer space). The planet with the deep oceans and millions of species already there. The planet that doesn’t need terraforming because its already terraformed.

So now knowing these two things.

Why the hell would we want to even consider moving away from here? Why would we want to cut down more forests here, if next-generation colonists wouldn’t do it on another planet in future? Otherwise, we’re just going to make the same mistakes on planet #2.

Here’s a simple thought experiment. Why aren’t we simply pretending to be living on a new colony already? That way we don’t even have to waste resources getting there.

Of course, getting other people to change is very, very difficult. All I can do is change myself. So what if I pretend that I am living on the planet Mars. What would I do if I was living over there? I would plant trees, not cut them down. I’d grow more forests that I cut down.

What else would I do? Why, I’d use my own urine as liquid fertiliser instead of going to the store and buying something that was obtained from a phosphate mine, wouldn’t I?

I think a lot of people on Earth have lost hope and they think that it’s almost like a “lost cause”. And I say: “fuck that”. I’d like to remind everyone that it’s FAR easier to get ourselves back on the right track here than to start from scratch over on Mars…

I do think that the biosphere is a lot more resilient than people realise. It just seems to me that people are giving up or losing hope on this planet that we all call home. But right now, Mars is in a much worse state than what we already have here!

I hope this has given a few of you some much-needed inspiration!

Would you want live on Mars? I wouldn’t. Please comment, and let’s get this discussion started.

LOCAL PETITION: Save Spring Gully from development, Royal National Park.

May 28, 2016 — leslie dean brown

The federal heritage listed Royal National Park is the world’s oldest purpose dedicated National Park.
20150701_160050_2-800x450

Upon dedication, in 1879, it was simply named “The National Park”. The “Royal” designation was added after the visit of Queen Elizabeth II in 1954. It is the birthplace of the National Park movement in Australia. If we can’t protect the Royal National Park and if we can’t protect threatened species and ecological communities within National Parks, what can we protect?

The land clearing will significantly impact the dense Bloodwood mallee which has been cited as supporting the scientific justification for a world heritage listing of the Royal. It is habitat to threatened species and supports a local sugar glider population which extensively feed on the sugary sap of the trees that comprise this dense woodland.

There are over 1,500 trees in the before drawing on the left that are missing from the after drawing on the right. Can you find them all? Read about the trick that has been used in the development application to hide the true extent of tree and canopy removal! They only show the tree canopies with trunks larger than 15cm. Trees with trunks smaller than this are just marked with a small brown circle that is almost invisible.

These diagrams substantially misrepresent the amount of existing tree canopy to be removed. 

These drawings only show the trees in and around the proposed inner asset protection zone. Hundreds more trees will be cleared in the outer asset protection zone not shown in these drawings.

Detailed data has only been provided for the largest 237 trees to be removed or pruned, including 34 large, mature, potentially hollow bearing, angophoras (important fauna habitat) that will be pruned to leave only 31% of their current canopy. The amount of canopy to be removed from these 237 trees alone is 8,687 square metres. The other 1,300 odd trees to be removed appear on the drawing provided but without details of how much canopy loss they represent.

Many hundreds more trees, possibly another 1,500, will be destroyed in the Outer Asset Protection Zone. An accurate estimate cannot be provided because most of this area has been omitted from the tree removal plan provided (appendix 16). See diagram below for location of outer asset protection zone.

The entire Bloodwood woodland along the top, southern side of the gully will be decimated. Every tree in this dense woodland bears scars from sugar glider feeding. The gliders chew through the soft bark to release the sap below. These unique stands of bloodwood growing in the deep sands at the base of the Jibbon Hill relic cliff dune have been cited as supporting the scientific justification for the world heritage listing of the Royal National Park. They demonstrate scleromorphic adaptation in response to the unique local geomorphology that developed in this area as the sea level began to rise some 10,000 years ago and the coast receded, pushing the relic cliff dunes, including Jibbon Hill, to their present location.

Sutherland Shire Council has recommended the former Scout land be acquired for addition to the Royal National Park.

On 10 November 2014, Council resolved to write to local state and federal parliamentarians asking them to support the acquisition of the former Scout land by the state government for addition to the surrounding Royal National Park.
