    We used to process those minerals and produce things such as Iron and steel, boat building thrived and we exported steel. Now all we do is export the raw materials and buy back the product, which is of poorer quality than what we used to produce. We are in the position of exporting vast amounts of LNG and not having enough for our own use. How good is that.

    If we accept that the climate is changeing then the assertions that is due to human activities is either TRUE or FALSE And we can either ACT to correct or IGNORE resulting in a risk matrix of 4 possible outcomes TRUE & ACT resulting in a livable globe TRUE & IGNORE resulting in a calamity for humanity and other life FALSE & ACT resulting in a livable globe and new industries FALSE & IGNORE resulting in life goes on as before. Whilst this indicates there is a 3 to1 chance of us being OK the other option is so calamitous that I believe we cannot in any conscience take the risk of not acting to reduce human production of greenhouse gasses into the atmosphere.

    It starts “ simulations from two climate models” and that is where reality ends. Fire conditions have been the same as now on several occasions since white settlement. What is different are: density of settlement failure to burn off in winter media coverage. Lack of historical insight. The Aboriginal burning management was adopted in part by the white settlers.it is only in the last 20-30 years that it ceased, due to misguided greenie opposition, lack of local involvement and the takeover of decision making by city based land management bodies. I saw an interview today with someone whose family grazed public land and burned off every winter until their land was taken by the Croajingalong national park about 20 years ago. That land was a part of the recent blaze.

    Deep ice corings in the Antarctic have yielded good information just recently as record of past climate /atmospheric conditions. If there had been good info refuting hothouse theory rising sea temps and acidification and all the rest, do you really think the majority of Climatologists are deceitful dishonest or stupid, and would just ignore it?. Also why would one trust the Minerals council for unbiased info or Heartland Institute, Breitbart or Koch brothers? Plimer saying carbon is black is certainly a non scientific comment relating it to the compound CO2. There's a lot of effort being put into denial at the moment by powerful interests with the making of money at the top of the list. Not the state of the planet. Saying WE lack humility " thinking" that humans can affect the planet on a grand scale when there's plenty of evidence that we can and DO affect if badly with heavy metals, Plastic, smog, acid rain, Glyphosate traces in everything soil salinity. fertiliser runoff. Ocean acidification affecting the shells of crustaceans and plankton the basis of the entire marine life food chain . Nev

    Homebuilt esky is the best, mine has 50 mm sides, a sealing lid and even a waterproof circle hatch in top from a boat. The hatch is awesome. You can access a beer without letting cold out or splashed water in. Sealed up a easy 80-100 kg of buoyancy. Unsealed and open with water approx 20 kg. More than enough for support. Also big ropes around outside to hang on to easily. Add a closed foam cushion and that works like a lifevest as well. Mind you I always have a proper vest on anyway. Worst case.....cold beer, food and a huge stash hole for fish. Mind you...I would have to really get Murphy onboard for trouble, the boat is a modified sail/row/power boat. It weighs 75kg but has 400 litres of positive buoyancy. Seats along sides are sealed chambers. I am doing new gunwales and transom for its half century birthday. But will make a version of the Capten collar to stabilise it for a bigger outboard etc. Boats are fun

    Goonie bags for safety. I can see the campaign in my mind. You are correct, besides allowing the world "cheap wine and a sailors growth". This Aussie battler is a life saver. Amazing what a simple thing can do when applied to boating. Also does not break when poorly stored. The other big saver is naturally the big beer/fish esky. Hundreds of half drunk Aussies have survived hanging onto a esky. My homemade one will support four holding ropes. It has alloy bubblewrap on the outside and can easily be seen from the air. But always wear sunnies, the reflection is a bitch.

    We were not allowed to change the Mullard off the ABC station. So I got a treacle jar and saved my pennies until I could buy a diode and earphone and made a crystal set with a coil wound on a toilet roll tube. A variable capacitor came from the local tip. Then I could listen to Elvis.

    All these things will be summarized in the cost of food. All my life, food has been so cheap that it has almost been free. Now if the "no climate change " people are right, then the price of food will continue to fall. On the other hand, if the warming people are right, the cost of food will rise. I reckon the warmists are winning in this last decade. And a good thing too, the price of food has been far too cheap, says me with my farmers hat on. The next ten years will be the telling thing. If the price of food drops, it means that climate change is not making much of a difference after all.

    2M of evaporation is probably on the low side. the "lake " NE of Mt ISA is 11 M deep and evaporation has made it useless. The water evaporated from Lake Eyre won't form cloud till it reaches saturation which might be over the south island of New Zealand. Nev

    According to Wikipedia, the area of Lake Eyre is 9,500 sq km. So with 2m of annual evaporation it would need 19,000,000 megalitres of flow per year to maintain level. That is just over 52,000 Ml per day needing to come down the channel. At a slope of 1:10,000 as recommended for design of irrigation channels, a 3m wide by 0.5m deep channel delivers 20 Ml per day. I don't know how to scale that up, but it is a factor of 2600 so the channel would have to be roughly 8km wide and 1 km deep! I may have made a mistake here, so would welcome a check on this. Another way to think of this is the Murray river flows about 10,000 Ml per day so it would take five Murray rivers to keep Lake Eyre full. But if we only wanted to keep one fifth of Lake Eyre full then we would only need one Murray River.

    You could be in real trouble if there's no shade trees in that situation. I remember once waiting with a mate on the Birdsville track for someone. It was January, around 50 degrees+ with no trees, on that Sturt's Stony Desert section. Very few locals travel that time of year and we were there for a few hours and saw no cars go by. If you had no water, you might not make it through the day in those conditions. Even laying under the Toyota wouldn't have helped as the stony, gravelly ground was so hot. Only option was to sit in the Toyota with the doors open. We had plenty of water, but it got me thinking how quickly someone could be in trouble without it.

    Prof. Connie A Woodhouse, a paleoclimatologist, was the originator of the term "megadrought", in the mid 1990's. Below is one of her initial study papers (1998) on megadrought, as it affected, and affects, the Continental U.S. It's 22 pages of fairly heavy reading, but essentially, what she is summarising, is that the droughts we know of in recent recorded, and reasonably-accurately measured climate history, may not be showing us the full gamut of megadrought conditions, and it is entirely likely in the not-so-distant future, that megadroughts of greater magnitude than those measured in say, the last 200 years, may occur over an extended period (20 years or more), and we need to be prepared for such events. https://journals.ametsoc.org/doi/pdf/10.1175/1520-0477(1998)079<2693%3AYODVIT>2.0.CO%3B2

    I was a member of the SES for years and in that time I fought fires, but nowhere near as serious as todays fires. I got out of the SES because it was becoming overrun with paper pushers. We had to have log books to record everything we did and our training. then they brought in payment for first aid taining, which I thought was a bit rich. The final straw was when they said that if a disaster was declared, we could make our own assessment of what was safe to do. Before a disaster is declared we had to stick to all the guidelines. That resulted in working with untrained people in dangerous situations. When I am hanging half way down a cliff with an injured person in a stretcher I like to know that the rest of the crew know what they are doing. It would be hard to have a form of national service, trained to answer to all the different types of disaster and untrained volounteers are worse than no volounteers.

    Think back a bit and remember that it was renewable electricity that caused the power lines in SA to collapse, leading to blackouts, so how can power lines cause the start of fires? At least that is what the pollies believe, or rather, what they want us to believe. We have too much fuel on the ground, which burns and eventually it can ignite the crowns of trees. than the chances of putting the fire out diminish drasticly. We have fires burning downhill towards habitation and there is nobody with any idea of how to control them, resulting in evacuation of whole towns. As others have said, the bush will recover, in fact there are some Australia species that require fire to produce viable seeds. On my own property there has been a change in the vegetation since I stopped burning each year. The grass cover is different, resulting in a change in the animals we see. I used to see Pretty Faced Wallabies commonly, now there are only Grey Roos. I don't regret not burning each year, but it is so difficult to get a permit to burn, that the fuel load is greater than I would like. I don't care what the powers that be say, I will protect my place with back burning if it becomes necessary. Especially after watching an easily controlled fire, allowed to jump a beautiful road fire break and threaten houses, just because the firies would not burn from the road towards the advancing fire.

    In the immediate aftermath of WW2, the greatest urgency was in re-establishing normal life for hundreds of millions of people around the world - by way of food and supplies of materials that were needed for rebuilding war-shattered regions. To this end, America set up and basically controlled UNRRA - The United Nations Relief and Rehabilitation Administration. UNRRA was only in full operation for 2 years - from 1945 to 1947 - although it had been formed by the U.S. in 1943, before being handed over to U.N. control, once that organisation was set up in 1945. https://en.wikipedia.org/wiki/United_Nations_Relief_and_Rehabilitation_Administration The Americans set up and re-arranged War surplus Depts on a regular basis - thus, no doubt leading to confusion and losses, as well as poor record-keeping, and lost records. The U.S. initially set up the Surplus Property Act in Oct 1944, and from that, created the Surplus Property Board. Then the Secretary of the Navy and the Secretary of the Army set up the Army-Navy Liquidation Commission, to deal with U.S. Military surplus that was located outside the U.S., apart from U.S. territories and possessions. Then, on 1st May 1945, the Office of Surplus Property was transferred via Executive Order to the Dept of Commerce, from the Dept of Treasury. I am presuming the Office of Surplus Property, was a different Dept, to the Surplus Property Board. On 18th Sept 1945, Congress voted to replace the Surplus Property Board, with the Surplus Property Administration. Another Executive Order dated 27th Sept 1945, abolished the Army-Navy Liquidation Commission, and transferred control of the disposal of War surplus, over to the U.S. State Dept. Another Executive Order dated 19th Oct 1945, transferred the Office of Surplus Property from the Dept of Commerce to the Reconstruction Finance Corporation. The RFC promptly created another Dept (!) - the War Assets Corporation, as its agency for handling surplus U.S. War property. Talk about throwing a hot potato around! Obviously, a lot of pressure from U.S. Industrialists was being applied to the U.S. Govt - the Industrialists did not want vast amounts of War surplus returned to the U.S., to damage new factory production sales. A final Executive Order dated 1st Feb 1946, reduced the War Assets Corp responsibility to just War surplus located in the U.S. Congress then declared the Dept of State was to be the sole disposal agency for War surplus located outside the U.S. https://books.google.com.au/books?id=gW0vgTVHUyYC&pg=PA570&lpg=PA570&dq=WW2+U.S.+Liquidation+Commission&source=bl&ots=Dg4Q0pSGMQ&sig=ACfU3U2pQaadB9tT5CkBXMjxInnXXdSkLw&hl=en&sa=X&ved=2ahUKEwjprbKHkebmAhVM7nMBHVaYCn0Q6AEwDnoECAcQAQ#v=onepage&q=WW2 U.S. Liquidation Commission&f=false China was a huge beneficiary of the surplus Lend Lease equipment left in the S.W. Pacific. Quite a bit of Lend Lease equipment and materials located in the S.W. Pacific simply disappeared in the aftermath of WW2 - pilfered by locals and other "entrepeneurial" individuals. I have no doubt some Australian and Kiwi individuals were amongst the Lend Lease War surplus pilferers. One initial War surplus contract, in March 1946, was negotiated between the U.S., Britain, France and Italy, whereby those 3 countries paid the U.S., US$532M, in a "bulk sale agreement". But a vast amount of Lend Lease War surplus still remained in the S.W. Pacific, and the War Assets Administration organised for a substantial portion of the War surplus in this region, to be handed over to the Chinese. I was surprised to find that America ended up indebted to China for some A£53M (approx US$150M) in the aftermath of the War, and this was the method the U.S. used to pay their debt to China - they gave them a large percentage of the still-operational War surplus equipment, plus the salvage rights to all the War scrap left in the S.W. Pacific. The Chinese ended up gathering up multiple millions of tons of scrap steel from the War zones in the S.W. Pacific, and in Feb 1948, China announced she had at least 2,000,000 tons of scrap steel available for sale to any global buyer. 1,000,000 tons of this stockpile of steel scrap was sold to Bethlehem Steel for A£9M (approx US$27M). The shipping cost to the U.S. was more than 55% of the sale value, but despite that, there was still a sizeable profit in the sale for the Chinese. https://trove.nla.gov.au/newspaper/article/42573328 America was getting quite desperate for raw steel supplies by the late 1940's, they had essentially mined out all their high grade (60% Fe) Hematite iron ore from the Mesabi Range in Minnesota, for WW2 armaments and equipment production, and were left only with low-grade Taconite (30% Fe), which had been discarded as waste for many decades. It wasn't until a clever U.S. metallurgist figured out an economic way to extract the iron from Taconite, via pelletising, in 1955, that the American steel industry could breathe a sigh of relief that they wouldn't become dependent on having to import high grade Hematite ore, to keep their massive steel industry going. Some of the U.S. steel mills in those heady days could produce a million tons of pig iron a day. That just gives you some idea of the staggering capabilities of U.S. industry, that produced the goods for WW2. Of course, the 1,000,000 tonnes of scrap purchased by Bethlehem Steel is only one days large mill production, on that basis - but scrap is an important part of steel production, and is needed to lower production costs, and provide an improved level of steel quality. Scrap has a known quality of iron, it has been previously refined, and with every re-refining of scrap, steel quality continues to improve. https://www.nrri.umn.edu/natural-resources-research-institute/news/davis-taconite

    I can confirm that stockpiles of surplus .303 ammo still existed in 1964-66 when Australia had switched to rimless rounds. The ammo was given to the cadet corps who had a great time shooting it off on range days, in Lee Enfields and Bren guns.

    Fellas, You do not want a big heavy car in a accident, especially a separate chassis 4wd. Great at low speed destruction of others but often kill everyone on board in a big one. They are mostly way too heavy and stiff to have adequate impact absorbtion in the impulse of a collision. They also love tipping over and killing all by squashing the roof, happens all the time. Sure bigger cars have bigger distances between the front and cabin but normally a lot more stuff that's heavy and crammed in there. Heavy cars have a great deal more inertia to absorb in such a small amount of time. Any forces it cant easily absorb will go to the cabin and its occupants. Yes in a ideal world, bigger and same safety features but bigger crush zones would be great but normally we drive compromises. The worst are the shortish and heavy for their size cars. Its all about the force being four times for a double weight increase. So it has to be four times as good in every area to save you. I have had a nasty in a big 7 series when hit by a 4wd turning into me at 90 km closing speed. The 4wd was toast and the BMW whilst fixable was written off by idiot insurance. In that case I would not want to be in a average car. No injuries to us but were in the 4wd. But I expect the smart would have done very well. Sure it would be punched sideways at a angle but that reduces a lot of the energy been stopped in a millisecond. Glancing blows are even better, if you can maintain a foward motion even at a large angle from straight- you are giving time for the forces to be absorbable and liveable on the body. Your crash zone can go from centimetres to metres. In the Smart test the angle shown really makes a huge difference to the effect compared to a flat hit. I am really impressed for how well it does compared to much bigger cars of its time or even today. Just watch all the biggest forces been transmitted around the cabin not into it. It might be tiny but its actually very safe. Extremely well engineered I have seen tests of smart vs much larger cars and it was safer- with the physics of crashes not all is what you expect. At uni we called it Lilliputian physics- because its is all a matter of scale and weight.

    The big killer in collisions, and in fact including aircraft collisions with terrain, is the rate of change in momentum of each party to the collision. Momentum is properly defined as the arithmetic product of the magnitudes of the mass of the objects and their pre and post impact speeds: M = m x v . The symbol for Momentum is "p". The law of Conservation of Momentum states that the total Momentum of the objects before the collision is equal to the total Momentum of the objects after the collision, expressed as: (p1a + p2a) = (p1b + p2b) Where the subscripts 1 & 2 identify the two objects; "a" identifies the pre-impact value, an "b" identifies the post-impact value The value "Impulse" is defined as the "rate of change of momentum", or {(p1a - p1b ) + (p2a - p2b)}/ (t1 - t2), where (t1 - t2) is the length of time the objects are in contact.It is the magnitude of Impulse that determines the effects on structures, including the human body. Imagine how a cricket ball can do damage. Firstly, the keeper underhand throws the ball to Short Mid Wicket. Not much velocity involved and the ball can be caught without its causing pain. Then the bowler thunders in and the batsman lets if go through the the 'Keeper, whose gloves have padding which deforms as the ball hits them, increasing the time for the ball's momentum to be transferred to the gloves and 'Keeper. Next ball and the ball rises up and strikes the batsman on the ribs and stops. Ouch! Next ball the batsman nicks it to Second Slip. The ball changed momentum because it changed direction and maybe picked up a tad from the motion of the bat. The ball flies to Second Slip, who places cupped hands in the ball's line of flight, and as the ball collides with the hands, Second Slip starts to rotate away from the line of flight, which increases the time the ball is in contact with the hands until its velocity is zero. Here's a video in which Impulse is explained

    Problem number one.... Who decide what value to put on an individual's lost potential income? Bear in mind a majority of volunteer firefighters in my area are past the age of employability (retired). Or those primary producers who might be called 'self employed'. Farmers might not have lodged a positive personal income tax return during the drought, and therefore have no provable income to be reimbursed for. Nevertheless they weren't able to work the farm whilst firefighting. It is impossible to fairly apportion any recompense. Do you have a cunning plan, Baldric?

    I don't like the idea of money in cash in your safe. Thugs just bash you or the wife till you open it for them. The safest thing is if nobody knows about it. If it is known, you need to keep some cash there just in case the thugs come. My daughter bought house in Brisbane many years ago, and a few years later they were changing the carpet and there was about 2 hundred dollars under the old carpet.

Using atmospheric physics to back up hs claim. . .Mars is far bigger than our Earth Moon but it has only a very tiny thin atmosphere, and No volcanically active core, so NO magnetic field to protect it from solar radiation. . .precluding even any advanced technology 'Terraforming' to make it liveable upon for Earth refugees, unless housed in protective domes, well shielded from aforementioned radiation resulting in limited travel outside. . . it looks as if, under current and sensibly perceivable technology, that any escape to the stars will not happen for another millennia or so, or until someone miraculously invents a Star drive to find a better planet or us to wreck, which must also have an orbital Moon to gravitationally control the tides and the weather,and a type G yellow star which places us in the comfort zone, AND the new planet is inclined enough to produce the seasons we are used to. . .
