The problem with science

August 18, 2016 — leslie dean brown

I think the problem is not with science, but with the entire 1st world civilisation.

Science is great and I don’t fundamentally disagree with any of it – but it doesn’t have any guiding moral or ethical principles. One problem with science right now is that scientists invent things without thinking through all of the possible consequences. And then some kind of “revenge effect” inevitably bites them in the arse later on down the track.

Another big problem is that businesses can take hold of any scientific discoveries and innovations they feel like and just exploit them for all they are worth.

So we know that this society will all too willingly absorb any new scientific knowledge into profitable new enterprises. Well ok – not so big a deal you might say – and it’s not. That’s the benefit of science. Right? Yes.

But then when those same scientists turn around and say: “No, now you are all going to have to change the way you do things, because we’ve figured out that this is not a sustainable industry” or “it turns out there’s this horrible side-effect”, no one listens. Not the people working for the industries, nor the people buying products from whatever those industries happen to sell.

So basically everyone is using the results of science whenever it suits them, and they are not heeding many of the warnings that science is giving…

People willingly accept, take and use the scientific discoveries. But the very same people never as willing to relinquish those very same inventions. Are they? [Read more…]

The problem with using biofuels in aviation.

July 31, 2016 — leslie dean brown

Recently on LinkedIn:

First, it’s a premise of sustainable, alternative fuels that their production actually draws down atmospheric carbon–the carbon comes out of the atmosphere to make the fuel. The carbon is released again when the fuel is burned. By (albeit partial and imperfect so far) application of that principle, vastly lower net emissions (on the basis of life cycle analysis) are now possible.

I understand all abot life-cycle assessment. Yes, true, biofuel crops do take CO2 out of the air.

But not if brazilian rainforest has to be cut down to make way for new plantation crops — because the native forest already does a way better job of taking CO2 out of the air than a crop with less biodiversity ever will.

So my question is: where are we going to grow all of the new crops that will be needed for this additional biofuel?

It’s no good saying that new sustainable crops will reduce the CO2 from the air if you harvest the whole thing every year and burn it again. That only releases the same carbon that was absorbed by the crop in the first place… so no net CO2 increase. (well that is probably an over-simplification, because some carbon dioxide no doubt goes in to the soil) [Read more…]

What this angry scientist has to say about climate change:

July 1, 2016 — leslie dean brown

Here I go again… why am I angry? Do scientists even get angry? Yes. Yes they do. Well I am angry. Very fucken angry!

I‘m angry at politicians in the mainstream parties. Because they aren’t doing enough to mitigate an environmental catastrophe. Most politicians today only care about one thing: money. The economy. Whoop-de-doo.

Scientists, if you remember from highschool, are the clever people. They are the nerdy ones with poor social skills. You’d think most countries would be run by the smartest of individuals. Are they? No. See, I think that’s where we’re going wrong. Our countries are run by politicians.

Likewise, I am angry at climate change deniers. Because they are now claiming that “climate change is a government conspiracy” (right, well if that is true it has to be the dumbest conspiracy theory I have ever heard, because the governments are the ones who support burning coal for fuck’s sake!).

Actually, I lie. Half of it is worry, not anger. For example, what’s actually worrying is that some people think an average temperature increase of a couple of degrees in only a few decades is at all “natural”. What’s worrying is that some people still don’t seem to grasp the concept of “rate of change”. I have seen on LinkedIn that the biggest climate change deniers are frequently either working for oil companies, have a vested interest in contruction, or are simply “uneducated fools”.

I find some people’s responses to climate change infuriating. Scientists are (mostly) a VERY clever bunch of people. If climate scientists are ringing alarm bells and making videos like this one, it’s enough to make me pay attention and completely change my lifestyle.

Right. I’ll say that again, but in a different way, because it bears repeating. Because I know that people skim read things. When the leading climate scientist, James Hansen, says (back in 2012 mind you) that “we have a climate emergency“, well, it’s enough to make me sell my vehicle. It’s enough to make me think up a new career choice, about how I can make the world a better place for future generations to come…

In science, we have to have a kind of ‘faith’ too. Scientists have faith in other scientists. We mutually respect each others’ fields of expertise. If I were to say, as a materials scientist, that magnesium has a hexagonal close packed atomic structure, I would hope the other scientists would give me the benefit of the doubt about that. And that is how the whole science community works. Things are checked and rechecked. Publications are reviewed. These people are working on these problems their whole lives. [Read more…]

My letter to Maurice Blackburn [PART 2]

May 23, 2016 — leslie dean brown

PART 2

[continued from part 1]

As a former scientist, knowing what I know, other forms of much more sustainable energy exist and yet the government allows this to continue. The WHOLE scenario is woefully depressing. That is basically the catalyst for my chronic ‘melancholy’ depression. The total lack of global accountability and responsibility to future generations to come…

Two decades ago, there was hope. Now, because of the reluctance for industry to change, I am fast losing that hope. Indeed, the situation is almost becoming ‘hopeless’. I just read that Australia has enough brown coal reserves to last another 465 years. Now WHO DOESN’T find that figure morbidly depressing I wonder? Who fuckingwell doesn’t? Eh?

I don’t want to live in a world that contributes to a worser future. I don’t want to use their dirty electricity. But what choice do I really have? I know that even if I buy ‘green’ electricity, the very same energy company supports fossil fuel companies.

I don’t want to pay taxes while all of this all continues. What’s the point? What’s the point of even working? Aren’t we supposed to be working for a *better* future? Well many people are working on it, on renewable energy technology like solar & wind power, yes, but some of these big corporations should have to pay. They are directly affecting my mental health right now.

The government has a duty of care to protect us. They aren’t doing that properly. Mining companies also have a duty of care to ensure that they won’t jeopardise our health or the future of this planet. They aren’t doing that properly either…

I’m willing to bet there are tens of thousands of people like me… if you want to find them, start with scientists. Start with climate change scientists, ecologists, even farmers, people like that.

Sincerely,
Dr. Leslie Dean Brown.

P:S I’d appreciate it if you could CC me Part 1…
unfortunately I lost that and I’d like a copy of it to put on my blog.

What this scientist thinks of NASA’s 2035 mission to Mars…

May 11, 2016 — leslie dean brown

The 2035 Mars space mission is said to cost an estimated US$1.5 trillion.

What are my thoughts on this? That sounds like an aweful lot of money to me — to keep four to six people alive on another planet— in my view it’s money that could be put to far better things, like keeping 7 or 8 billion alive on this one.

To put things into perspective, it’s the equivalent of spending 94% of Australia’s Gross Domestic Product… for what? A dozen or so people to have the trip of a lifetime… at the most? That’s one hell of an expensive postcard!

If I personally had US$1.5 trillion dollars to play with and I wanted to ENSURE the future surivial of the human race, why, do you know what I’d do? I’d buy up all the wilderness areas up in poorer countries. I’d abandon that silly space mission. That’s what I’d do. And this is coming from someone that liked reading Carl Sagan’s cosmos… [Read more…]
