I am picky with terminology, so let me explain. . . I strongly urge people to stop calling anthropogenic global warming a “hoax” or “scam.” It's not. There is indeed a legitimate underlying scientific basis. While a consensus of scientific opinion is irrelevant, as Dr. Judith Curry and Dr. Roy Spencer have pointed out, there is general agreement within the scientific literature on these three things: ➊ Global mean surface temperature (GMST) has risen about 1.2°C since 1850. The warming since 1980 is about as equal in magnitude and rate as the early 20th century warming from 1910 to 1945. In general, it has been warming for >250 years. 📈 🔗metoffice.gov.uk/hadobs/hadcrut… ➋ Burning of coal, oil and natural gas for energy has increased atmospheric carbon dioxide (CO₂) levels by ~51% since 1850. We know this because there is an isotopic fingerprint in the decrease of C13/C12 ratios. While this is not uniquely indicative of anthropogenic origin, it is a pretty solid indicator. 🏭 🔗gml.noaa.gov/education/isot… ➌ Earth's average surface temperature is a function of energy gain versus energy loss. Given there is a radiation spectrum on CO₂ in the infrared (IR) band of the electromagnetic (EM) spectrum, all else constant, adding more of it to the atmosphere should reduce the rate of cooling by emission of IR to space. In effect, it induces a cooling tendency in the stratosphere and a warming tendency in the troposphere. This has in fact been observed. 🌈 Beyond this, there is no agreement on: ➊ How much warming is man-made? The claim that virtually all of the warming is anthropogenic is based squarely on modeling studies. The IPCC's “best estimate” of greenhouse gas (GHG) contribution to GMST change since 1850 is +1.5°C ± 44%, and their “best estimate” of aerosol forcing is -0.5°C ± 100%. That doesn't sound like “settled science” to me. 🔗ipcc.ch/report/ar6/wg1… (pp. 439-441) ➋ The exact equilibrium climate sensitivity (ECS) — a measure of how much warming results from doubling CO₂ concentrations once a new local equilibrium is achieved — and amount of warming left in pipeline for the 21st century. 🌡️ ➌ Is warming dangerous for humanity and life on Earth as a whole? Is it a net benefit or a net drawback? This is not a settled matter, regardless of what experts say. The findings in the body of literature are mixed. It does not unequivocally support their notion that warming is catastrophic or even bad. 🤷‍♂️ ➍ What are the best measures for adaptation and/or mitigation? How should energy policy be handled? Do we change zoning codes? Do we construct seawalls to combat creeping sea level rise? What is the cost-benefit analysis of decarbonization efforts? So, there is in fact a legitimate scientific basis behind global warming theory. The basics are pretty well understood; the devil is in the details and the science is far from settled. ❌ The case isn't closed. That book remains wide open on the table. 📖 However, what is indeed a scam is the push for “Net Zero” CO₂ emissions by 2050. A legitimate scientific issue has become captive of a Malthusian religion by power-hungry elected officials and unelected bureaucrats. Climate policy is an anti-capitalist, anti-human movement. These people push for one-world governance where you are told what you can and cannot eat, what appliances you can and cannot buy, where you can or cannot travel and want to force us to adopt a carbon credit cap and trade system in a cashless society. The policy is the scam, not the basic underlying scientific theory.

@QuandiGirl22 @Craig_Foster You wouldn't notice a damn thing, refugees account for 0.5% of net migration. Asking for responsible migration, in-line with housing, services and infrastructure growth - does not a Neo Nazi make. Are you lefties allergic to nuance?

@Craig_Foster I wish every refugee could walk off their jobs for a day to show the Dutton followers the folly of their beliefs. But they wouldn’t because they have ethics & standards. Would love to delve into the family trees of the Neo Nazis. In particular how they came to live here

Melbourne, Australia in recent days. Following on from Brisbane. Neo-Nazi groups hear the public normalisation and defence of exclusion, demonisation, racism, hate very clearly and respond accordingly. If Australia wants to condemn hatred and protect our multicultural society, this is where the outrage should be directed. Not at students protesting against genocide, vulnerable communities or people fleeing persecution.

"Quantum mechanics is just thermodynamics in imaginary time." It sounds like a hand-wavy, quasi-philosophical statement. But with a brief dive into the relationship(s) between hyperbolic and parabolic PDEs, it becomes possible to formalize it mathematically. (1/16)

Great thread, we worked on Myrtle Rust when it first entered Aust and the concerns it would wipe everything out then. But these Myrtaceae's tend to develop resistances through genetic drift pretty fast. Same with Botryosphaeriaceae (canker), Diplodia, Phytophthora, etc which all cause severe kinotannic acid expulsion. Ginger disease needs genuine funding and study to ensure it is heat-induced and not something more nefarious. Climate change is slow when compared to fungal spread, which is evolutionally beneficial for our eucalyptus, facilitating phylogenetic process with a larger buffer. Fingers-crossed

First it was the strange hue of the trees now it’s a real life nightmare. This is very hard to take, it must be shared because none of us can escape this. A catastrophe like we’ve never known is unfolding & exploding at an incredible rate. 🧵 #tasmania

Dear Australians, It's time you became aware that ... Australia's economy is a giant plutocratic rent-seeker Ponzi scheme underpinned by deliberate, low quality mass-migration and it is primed for a MASSIVE implosion. Western societies are turning against the mass-migration policies of Western plutocratic governments, and when the Australian government (eventually, necessarily, and inevitably) turns off the mass-migration spigot the Australian economy will crater. The most frustrating part of this is that when Australians cry for more legislation to fix their problems, the plutocrats who run our government giggle with glee - because they know that more legislation only helps the plutocrats and not the people. Australians need to learn (and I fear they will only learn through the pain of experiencing socialism - as was learned by the people of Argentina) that the only way to change our current trajectory is less government (not more). Buckle up Australians (who are not government employees getting wages that are insanely disconnected from everyone else), you're in for some very rough times! _ #auspol #auspol24 #auspol2024

JULIAN ASSANGE IS FREE Julian Assange is free. He left Belmarsh maximum security prison on the morning of 24 June, after having spent 1901 days there. He was granted bail by the High Court in London and was released at Stansted airport during the afternoon, where he boarded a plane and departed the UK. This is the result of a global campaign that spanned grass-roots organisers, press freedom campaigners, legislators and leaders from across the political spectrum, all the way to the United Nations. This created the space for a long period of negotiations with the US Department of Justice, leading to a deal that has not yet been formally finalised. We will provide more information as soon as possible. After more than five years in a 2x3 metre cell, isolated 23 hours a day, he will soon reunite with his wife Stella Assange, and their children, who have only known their father from behind bars. WikiLeaks published groundbreaking stories of government corruption and human rights abuses, holding the powerful accountable for their actions. As editor-in-chief, Julian paid severely for these principles, and for the people's right to know. As he returns to Australia, we thank all who stood by us, fought for us, and remained utterly committed in the fight for his freedom. Julian's freedom is our freedom. [More details to follow]

err PWR reactors can restart in peak xenon - xenon precluded start-up only applies when core fuel is <5%, which doesn't happen on AP1000s and every SMR design has fission removal systems inbuilt + staggered refuelling, hence flux levels can't drop low enough by design. Also, how do peaker plants fit into net-zero? don't say hydrogen, because none exist without enormous NG blend ratios.

@JR07387638 @FissionableF @simonahac Yep, a shutdown reactor can't just ramp up again, it has to wait 1-2 days before it can be restarted because of the Iodine pit. We need peaker plants, not fixed generators like nuclear.

☢️ wait 'til the 10 million aussies living under a solar array find out their solar panels will have to be turned off routinely to accomodate the inflexibility of nuclear. reneweconomy.com.au/nuclear-lobby-…

No ramping is done with renewables and much less of them - Those proposed plants are largely running 80% capacity factors now (Callide/Tarong CFs below), nothing would change, same output. Having unlimited power for 6hrs a day is useless if it's not going into storage to dispatch at peak load times. Solar is cheap (industrial is, roof-top not so much) but it's also an incomplete composition. Outside of hydro/geotherm which is geologically limited here - you're stuck with batteries for storage, which are insanely expensive at grid scale compared to nuclear. So it floating offshore wind, but we're pushing for that too.

@FissionableF @simonahac Are you suggesting that new reactors will be flexible enough to ramp down to accommodate solar during the middle of a sunny day? This could be zero power for some days and would it not then make nuclear power even more expensive if it’s only needed when the sun doesn’t shine?

@DaftandD @simonahac Those coal plants being replaced are run at above 80% CF, it's a direct replacement for baseload. You need 6x the dispatch storage to achieve the same thing with renewables. Go do a LCOE on that, it's trillions - even AEMO agrees.

@FissionableF @simonahac Frequent ramping can also lead to wear/damage to critical control mechanisms and cause lengthy repair downtimes. Not to mention nuclear that isn't operating at peak capacitance won't recoup outlay or LCOE. The World Nuclear Industry Status Report 2023. worldnuclearreport.org/The-World-Nucl…

AEMOs forecast dispatch capacity is 46GW for 2050 - Which is 24% at 11GW Nuclear. 3.7% is just garbage. That graph is just forecast range by storage type (doesn't include nuclear) and shows how variable renewables are and a good example of how expensive too. You'll need 6x more storage to hit a reliable 46GW dispatch capacity 🤣

@breakfast_dogs @brandon_munro Why would you be looking at nuclear share of current grid load? It won't be available for 15-20 years. Nuclear share of forecast grid load when it will be available, according to AEMO, who should know, if anyone:

The Australian renewables lobby is losing its mind. UAE went from zero to 5,400MW of nuclear power (similar to what Peter Dutton is proposing) for US$25B (A$37.5B). And decarbonised 25% of their grid in the process. This renewables body say A$600B - 16x the experience of new-comer UAE. Reeks of desperation to me...? It is a shame the renewables industry has decided to feel mortally threatened by #NuclearPower - we have the best chance of decarbonising - without economic destruction - if *both* nuclear and solar/wind options are deployed to their full potential.

@olthwaite_eric Yes, that's a BWR 1200 in the graphic, the PWR AP1000 proposed for Australia has the same ramp rate, 5%/min. We define modern as GEN III onward.
