We've got all sorts of termites here. Look up Magnetic Termites, we have those up the top end. Their mounds are flat sided and all run on a north south axis. Looks really weird when you first see a valley full of them, like a giant's graveyard. They're all 5 metres tall or more.@Outdated, it's amazing what you guys have down there, I have never seen an ant nest like this before. Spinifex termites.
Aye, tinkering with nature will probably always be full of surprises. I can imagine a vast effort to clone new Mammoths only to find out that Mammoths kill humans on sight, unlike Elephants, which I hear find us cute.I've tried to get my head around all this, looking at individual related climate studies, such as glaciation, and sea changes (temperatures, currents, sea level, changing bio-diversity, etc etc etc ...) and more, and I came to the conclusion that we know far too little about how everything interacts (hardly surprising considering the complexity and lack of knowledge) never mind fully understanding the individual systems, and attacking particular targets won't help (or not enough) and will very likely have unintended negative effects elsewhere.
It seems to me the real problem is the current human population, being artificially and unsustainably far too large, and the current global commercial and cultural system of expansion being the fuel that our societies run on, regardless of their political bias.
The only way I could see a 'fix' would be a fundamental change in how humans live, requiring a complete change of how we view our place in the biosphere that created and sustains us. Global government of some sort would be needed with the collective power to control even the most powerful nation states and to try and force that would just result in world war. It's clear we lack the motivation to make this change voluntarily, so nature will do it for us.
But that shouldn't be a reason to be downhearted. Without the last mass extinction we wouldn't have evolved. It can be viewed that we are just an indivisible part of the whole of whatever is considered living matter on the planet. Just as birth requires death, so the creation of new species comes from the diminution and extinction of others. We sometimes speak of our own evolution, but don't think of all the possible ways this could happen and what would come from us.
We are all subject to being cursed to "live in interesting times".
Still, it's a bit of a bummer really!

I guess being north/south oriented, they'll probably get the best exposure to the sun all year round? i.e. could it be an external heating effect they've evolved to exploit?We've got all sorts of termites here.

That's exactly it. They catch the early morning sun and the late afternoon sun full on their flat faces, but during the middle of the day the sun is mostly striking them on the edge so that the poor little ants don't fry.I guess being north/south oriented, they'll probably get the best exposure to the sun all year round? i.e. could it be an external heating effect they've evolved to exploit?
I love opals. If I were given the choice between an opal and any other valuable stone, diamonds, etc. I would choose the opal.Australia has weird ants.
I watched something yesterday called "Opal Hunters Red Dirt Road Trip". That's a pretty good series. Australia is an interesting place. And weird.

I am afraid I will be unable to travel anymore, but if I can, I’d love to go to Australia (and Norway ).
I’ve seen the trailer but can’t see the show without spending a lot of money.Have you seen this?:
Outback Opal Hunters (TV Series 2018– ) 7.0 | Documentary
I have been watching this series for a while and I think it's very interesting, good series. Opals are special, amazing colors.

Australian opals are far superior in quality to any others. Within Australia there are different mines and the characteristics of the opals varies from mine to mine.I'm not sure why but Australian opals seem to show a lot more blues than those found in the northern hemisphere.
Opals are made from bones and sea shells. We've found a few partial skeletons made of opal, and one almost complete one, a Pliosaur called Eric. A few years back there was news of another complete skeleton being found, but that went all quiet again. They probably did find one, the same thing happened when they found Eric, too many people knowing where it is would make it a huge security concern.

Hey! I make the puns round here y'know!Also just rocks.
Adelaide breaks 100-year record with coldest September morningWe had a start to winter like that, it looked like it was going to be a huge ski season here. Then we had a winter heat wave that ended the ski season just a few weeks after it began. Now that spring has started we're getting a cold blast from antarctica and it's colder here now than it was all winter.
The trouble with those one night only freezes is that’s all it takes to ruin the harvest of any frost sensitive crops.
To be frank, it would very much depend on which organs!If you needed money, would you sell your organs?
I would imagine a lot of it would be things like kidney's - e.g. patients on dialysis (with deep wallets and amoral attitudes).Maybe Hiroshima victims, who knows.
And that's exactly what happened. A warm dry spell with no rain when we were supposed to be having winter so the crops were in very poor condition, then frosts when they were in no state to survive. 75% crop losses in South Australia and western Victoria.The trouble with those one night only freezes is that’s all it takes to ruin the harvest of any frost sensitive crops.
I’m sorry to hear that.And that's exactly what happened. A warm dry spell with no rain when we were supposed to be having winter so the crops were in very poor condition, then frosts when they were in no state to survive. 75% crop losses in South Australia and western Victoria.
Most can't even be harvested for animal feed which is also in short supply.
Normally about now is when we're getting ready to harvest, especially wheat, but there's not much to harvest this year. This means we'll have none for export and that's going to create hardship in a few of our neighbouring countries, especially Indonesia. A lot of Asian countries are too overpopulated to feed themselves and rely heavily on our exports.I’m sorry to hear that.
There's been a lot of changing trends in Australia the last few decades. Farmers are starting to realise the benefits of more eco-friendly practices, some for idealistic reasons but many simply forced to accept it through climate change and adversity. Maintaining a certain percentage of native bush on their properties because this reduces the amount of insecticides they need to use by attracting natural predators, etc.Is it just me in my insular fashion who's missed reading anything much in the general news media about this, but the food industry, especially at the source of production of raw materials, farming in the main, has a negative environmental impact second only to fossil fuel and including carbon pollution (though that's far from all), and most of the methods used for bulk production rely on a moderate and consistent climate?
