I can't find my post - funny about that.
So I'll just sit back in the naughty corner ..... again

I can't find mine either saintpeter - I guess my comments about climate change deniers were too much for some.
Given the usual profile of most deniers, I guess it's not surprising.
I'd join you in the naughty corner if I thought I deserved to....

In this context denier was coined in terms of the Holocaust, it is now used to imply the same horrid mindset for people who disagree with you.

Denier, the word you use when you want to shut up your oppositions arguments because you can't think of anything else to say!

The use of the term denier in the context of Climate Change is quite simple.
A denier is one who does not accept what the majority of credible, non-partisan, independent scientists have been telling us for years.

Most teenagers have the attention span of a goldfish.

True.
I seen it on Facebook when l wuz researching stuffs.

I think the post suggesting someone should drown was removed ( thank god) so anyone quoting that post might have been too.

I think that post was made by someone that sympathises with the Christchurch killer and also hates most people that aren't white Christians. The self appointed Seabreeze White Power advocate.
He gets upset when someone calls him a bigot, go figure??

What a load of nonsense this post is.
Someone has a different opion to you and out comes the nasty, nasty name calling,

Even the boffins don't agree about climate change.
Grow up.

I've got teenagers and like Greta they have a nice way of cutting through to us Boomers - What if we are Wrong?

I wouldn't sail with suspect rigging, I wouldn't go if the forecast looks nasty. So, call me old fashioned, but I prefer the precautionary approach.

Even if the science turns out to have overstated the threat, seems to me like we, through the changes advised, we will get a better environment. Now, if we don't change, and leave our kids and the planet with a big mess...that is my definition of dumb ass

Yeah, what if science overstated the threat and we created a much better world for no good reason......????

Ok,
Henny Penny.
You win.

The planet needs less opinionated folk on it, that's essentially it...mostly

And less throw away toys...like my Super crap saw which buggered up after 17 mins of use.

So do the right thing...
stop breeding.
and start giving decent birthday/xmas presents.

Thank you ball boys
Thank you ball girls

Sailing to a conference using a carbon fibre boat to promote "save the environment" is like the marketing con job of "clean" solar panels. What solar panels actually do is transfer the massive pollution created in making them somewhere else where we dont see it. Smelting the silicon, copper and glass in a solar panel requires massive energy and the pollution created by supplying that energy appears as smog and dead rivers in China.

See asiancorrespondent.com/2011/09/the-hidden-pollution-caused-by-solar-panels/

Same with carbon fibre. It is actually right up there with the worst manufacturing material you could use as far as damage to the environment goes. A quick Google shows you need to burn about 10kg of hard coal to get 300MJ of energy to make 1kg of carbon fibre. How heavy is that boat? I am a greenie but grandstanding rubbish doesnt help anything.

www.theguardian.com/sustainable-business/2017/mar/22/carbon-fibre-wonder-material-dirty-secret

We need to deal with facts. The Ms is riding on a boat the construction thereof that caused more massive environmental damage than most other things you could possible make. The Ms would have been better to add her 60kg to the weight of the A380 which was flying the route regardless!

I had a detailed post last night on the subject that got somehow deleted on my computer as I tried to attach a link to a paper titled:
Climate change and the Precautionary Principle.
It was written in 2006 and it is very interesting with respect to how things have progressed since it's publication . Here is the link. Well worth a read :
www.nusap.net/downloads/Climate_Change_and_the_Precautionary_Principle.pdf

This debate should not be "Lefties verses Righties". It is the politicians who have framed the debate as such.

I'm not left or right but vary my position from subject to subject and I'm not smug or superior. Nor am i naive. The word implies lack of experience, wisdom, or judgement and i refuse to be put in the box of someone else's narrowly defining one liner. ( and Bara I'm not really offended at your post, just using it as an illustration to make a point. I hope you don't mind. )

With respect to communication i will make two statements as it is with poor communication that much of the problem around the climate issue arises.
False assumptions pave the way to prejudice.
Accusations, more often than not, say more about the accuser than the accused.

and this from Morning Bird

"In this context denier was coined in terms of the Holocaust, it is now used to imply the same horrid mindset for people who disagree with you.
Denier, the word you use when you want to shut up your oppositions arguments because you can't think of anything else to say!"

I'm sorry but you are way off the mark with respect to many who use the term. Of course in some situations and exchanges in hostile debates you would be absolutely right. ;) however Datawiz is more on the mark with respect to how many intend to be heard and understood when using the word.
My use of the word in the poem i wrote was definitely a statement to the political leaders it was aimed at. Leaders should lead from an informed and inteligent position and not play manipulating games with the electorate and our leaders are far from being fair dinkum in their media statements. The lack of integrity in Political leadership on all manner of subjects is staggering and will have devastating consequences for Australian people.

There seems to be an ominous silence on the sailing la vagabonde channel of late.

With the funding and tech they have on board I don't think it an issue of not having internet connection.

Maybe Greta has stared them down with her "How Dare You" grimmace for actually eating fish they caught along the way, or maybe it was "How Dare You" start that diesel engine and create a carbon footprint on my trip back across the Atlantic.

Possibly Riley and Elena are pondering the wisdom of letting Greta The Gremlin on board.

For a more balanced view, I have been following the thread on Sailing Anarchy. 18 very long pages!

For my part blaming previous generations for the industrial revolution and its result is nieve and achieves nothing. Noone knew the Earth was an air tight ball back then.

Sailing on a carbon fibre boat to reduce carbon foot print is ridiculous. That boat would have cost hundreds of tonnes of carbon emissions to make!! Its the worst of the worst in materials. The voyage has been a great unpaid commercial for carbon fibre. Good job boys.

Over population is responsible for most of the climate change problem. Everyones desire to procreate. But silence about that! Should previous generations be blamed for having children?

I am very much an environmentalist like most yacht sailors but considered and well expressed facts beat TV grand standing any day. I deal with plenty of red necks who ridicule climate change and that offensive blaming of previous generations who were only starting to understand the world back then has turned them right off. Well thought out explainations would not have.

Nah, I think you have it a bit wrong there.
She's not blaming the industrial revolution. No one could have known how that would have turned out all those years ago.
She's talking more about the fact that we've known there's been a massive impending issue for about 40 years now and nothing's been addressed.

I think the traveling by yacht thing is a non issue. The haters would be hating and accusing no matter how she travelled.

I think best to put all the hair splitting bull**** aside and listen to the message. I don't know how anyone could see that as a negative thing.

Go Greta!

Agree entirely!

Is it just me, or is this at least a step forward:
I don't see many comments suggesting Climate Change is Crap
Plenty of suggestions that there may be better ways to reduce our emissions
References to the precautionary principle and emissions intensity (per person) or emission scale (size)
Comments informing us of the embedded emissions in different materials and respective ability to recycle

Thanks for contributing here in a civil and constructive way, and thanks to our very own La Vagabond for giving us the incentive, and to that extraordinary 16 yr old for passionately challenging us all.

So great that people can make a career mocking a 16 year old. She is certainly having an impact.

Yes we do need to alter our modus operandi and quickly. We are on the same side. Cars are worst. I agree. The knowledge I am using is what you correctly say is vital to saving our planet. If it ever gets used. Re your questions re the carbon fibre. This is the energy (embodied) to make boat building materials (from composites uk).

Forgive the longness of this but since you asked.....

MaterialEnergy Content (MJ/Kg)
Carbon Fibre 183-286
Glass Fibre 13-32
Polyester resin 63-78
Epoxy resin 76-80

The Outremer website states its built extensively from carbon fibre and weighs 10 tonnes. Simple maths and that data says making 10,000 kg (10T) of carbon fibre will use 10,000 x 183-286 MJ of energy. Maybe the amount of carbon fibre in the boat is less its but its right up there. (Lets say 240 MJ because I worked once on a process that used that much). So we need 2,400,000 MJ of energy to make that much carbon fibre. There is 29300MJ of energy in a tonne of coal. Maths again 2400000/29300 gives burning 81.9 tonnes of coal to make a 10T carbon fibre boat. Burning 81.9 tonnes of coal produces 153 tonnes of carbon emissions. (Heavier because the carbon combines with oxygen). The EPA says the average car produces 4.6 tonnes of carbon emissions per year.

So re cars versus this carbon fibre boat, its responsible for 33 years worth of one cars emissions. And its for someones pleasure, not a useful purpose.

Its true the electricity they use in some cases might be nuclear but vast majority not. Those numbers assume 100% conversion efficiencies which the real processes are not (More like 70%) so the numbers are actually far far worse. We urgently need to save the planet but would you do that by driving 33 cars around for a year? It would be ridiculed but thats what they are doing! I am absolutely in favour of saving the planet but I would not grand stand on a carbon fibre boat to do it!!!!

No forgiveness required, more like thanks for the thoughtful reply :)

Comments about points:
- Material Content, yeah wow (I tend to bandy about the idea of orders of magnitude when tossing loose numbers around) carbon being a full order of magnitude greater impact is surprising.

- Outremer at 10 tonne is also surprising since it's probably comparable in living space and payload to a Leopard 40 with extensions which weighs the same, makes me wonder how much carbon might really be in there... Could be marketing speak. But it isn't being discarded at the end of the journey so it's embodied energy isn't lost. Also how many people do you know who drive EVERYWHERE, even to the gym :) :) ha ha, is that a useful purpose??

- As to getting energy to use for carbon capture, yes we need to invest HUGE sums of money into nuclear to make it viable, I did read in one of the Carbon Solutions (??) engineers blogs talk of it costing as little as $1 / litre. However think of the side benefits, basically you would break the whole warring over squished carboniferous trees cycle which has plagued the past >100 years, have the ability to set atmospheric carbon as required, stop the shipping of vast amounts of oil around and kill off the sketchy deep sea drilling operations planned.

It would be a huge job to create several thousand carbon capture plants but strangely humans manage to mobilise to far greater levels for national identity or fear...

Personally IMO putting a $0.50 / litre tax on petrol to pay for turning Australia into a global superpower in creating ecologically sustainable fuel would be a smart move, far smarter than the government's plan to use electric cars... Although since it would cost people an extra $5.00 an hour to sit in traffic they would go nuts :( :( :(
