There is little to support that the biosphere is self-regulating (which is no doubt what you mean by Earth ecosystem; and ecosystem is a biological community in a certain area plus all the abiotic components involved). Indeed, there are usually multiple stable points and limit cycles in even simple dynamical systems, such as competition or predator-prey interactions. Within a single population there do appear to be some factors that are self-regulating, but often popns. are regulated by extrinsic factors. Want math? Extrinsic factors? Do you mean from outside the Earth? We are in a mostly closed system. Unless you are talking about the sun radiation or a meteor hitting earth, I don't see too many other extrinsic factors.

semente Posted September 29, 2019 Author Share Posted September 29, 2019 There has been an awakening in the Force... Austrian elections: support for far-right collapses Support for Austria’s Freedom party (FPÖ) has plunged by more than a third as voters punished the far-right group in national elections for a corruption scandal that brought down the government. The former chancellor Sebastian Kurz, 33, looks certain to reclaim his position as the youngest leader in the world after his People’s party (ÖVP) secured 37.1% of the vote – its best result since 2002. The Green party was the other big winner on Sunday, achieving its best result at national elections with 14%. The centre-left Social Democratic party (SPÖ) plummeted to a historically low 21.7% but was still the second-biggest party. https://www.theguardian.com/world/2019/sep/29/austrian-elections-exit-polls-collapse-far-right-support-sebastian-kurz-victory Fluffytime 1 "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment

That's why I mentioned methane. We need to change cropping systems in the way agricultural land is managed. Especially in crops that are renewed annually, such as grains and fodder. Renew trees for species not so much and easy combustion, such as conifers, which is what is most in North America and Europe. I keep in mind the constant fires in California! Of course, emissions from vehicles and fossil fueled industry is a crime, which we will gradually improve. There has been a good deal about it, but we need a lot more. https://www.extension.iastate.edu/agdm/articles/others/TakApr08.html https://ameriflux.lbl.gov/methane-production-and-emission-in-upland-and-wetland-trees-and-forests/ Roch Link to comment

esldude Posted October 14, 2019 Share Posted October 14, 2019 Hey, sun shades at the Lagrange point L1 is what I'd suggest. Get the material from moon mining to build and put it in place. Much less of a gravitational well operating from the moon. Blocking 2% of the sunlight will counteract all the carbon increases in the atmosphere. Best plan to put into place if you aren't some maladjusted fearfully panicked northern European teenage girl. Maybe someone should point it out to her as a solution.

Roch Actually I do consider moderately long term this is the best idea (the shade at L1). We know what it would take. While a massive undertaking so are the other solutions. It would also stimulate some other technologies. It would be the most finely controllable of all solutions. We know for sure it would work. If I'm to believe Democrats in the USA, money is a complete non-issue due to MMT. Even they have advisers that tell them you can't have an unlimited GDP, but with the place to put excess production at L1 it should take right off. Developing the ability to place those shades also likely leaves us well able to have orbiting solar power plants. Meaning we can quickly stop fossil fuel use. Is it doable soon enough? No. So far neither is anything else proposed short of everyone becoming enlightened world wide and voluntarily living like it was a millennium ago. Anybody have a better idea?

Carbon capture can then be worked on over a longer time period as the interval until temperature ratchets up has been taken care of. Eventually taking care of carbon via carbon capture will help with ocean acidification though maybe not before damage is done. You have to admit the current prospects of controlling ocean acidification are around the slim and none category. Carbon capture or shade? Both are too expensive to pursue at once. Choices have to be made. PV deployment is likely to proceed thru the sheer economics of it. Oh well, chances are none of it will be accomplished in time. Some group of people will in some way adapt to changed conditions and some of the earth may or may not become too hot to inhabit full time.

As noted by artists in recent interviews, including Yorke’s visit to the Late Show, it’s difficult for an environmentally conscious touring musician to function conscious-free given the ongoing climate crisis; the duplicity is often a target of the media and climate change deniers. “Dear journalists who have called us hypocrites, you’re right. We live high carbon lives and the industries that we are part of have huge carbon footprints. Like you — and everyone else — we are stuck in this fossil-fuel economy and without systemic change, our lifestyles will keep on causing climate and ecological harm,” the open letter notes. continues here -> https://www.rollingstone.com/music/music-news/thom-yorke-david-byrne-eno-extinction-rebellion-open-letter-900296/ Teresa and JediJoker 1 1 "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment

I agree. I also have first hand experience with whisker growth in Telecommunications Relay Sets that caused a s/c to the frame of the relay sets . This caused the need to replace many 100s of expensive springsets . In later days with Telstra I pioneered the technique of charging a large value capacitor to the exchange voltage of 52V to apply directly across the fault, which vaporised the whisker and restored the relay sets to normal operation. I never saw the faults reoccur in those relay sets either. marce and esldude 1 1 How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

The more we learn about the side-effects of food production, the more the act of feeding ourselves becomes fraught with anxiety. How can we be sure that certain foods are “good” or “bad” for society and the planet? As Tim Lang, professor of food policy at City University of London and the co-author of Sustainable Diets, puts it: “When you come to ‘judge’ food, you end up with an enormous list of variables, from taste to health outcomes to biodiversity.” Here are some of today’s most controversial products – and some thoughts that may help you when shopping. https://www.theguardian.com/environment/2019/nov/20/to-eat-or-not-to-eat-10-of-the-worlds-most-controversial-foods "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment
