bawfuls posted:it was 460,000 in the US over the last 20 years I think. So a casual 20k a year, give or take I thought only like 20k people work for the coal industry. so it’s like if there was an industry with a 100% fatality rate for its workers. good thing its just killing random strangers instead though, otherwise the obvious correlation would be too much to ignore, probably.

TACD posted:this rules, I’ve somehow never heard of this before and am geeking out over the wiki page.  yeah! Beta+? Proton spits out a positron and becomes a neutron: move diagonal down right. Beta-? Up and to the left. Absorb a neutron, move to the right. Alpha? Diagonal down to the left two spaces. Fission? Who knows! ... And yet averaged over a large number of fissions and the products are normally distributed over two peaks with known concentrations. One thing that still blows my mind is a free neutron is, itself, unstable. If it doesn't get absorbed for long enough, it'll decay too... Into a proton! A dead neutral particle spontaneously causing a new atom of hydrogen to form... It's like the universe wants to be more interesting

Even that overly optimistic article I posted from some bullshit climate report generator said that things looked good because we were probably going to limit warming to less than 3.7C.

All of this poo poo stems from the latest generation of earth system models having a lower upper bound for equilibrium climate sensitivity. They treat this as a win while ignoring every other effect that isn't long-term stable temperature. It's the same dumbassed mindset that made them all use 2100 as a target year in models.

the BBC has a long article about the 1.5C figure in general https://www.bbc.com/future/article/20231130-climate-crisis-the-15c-global-warming-threshold-explainedquote:the 1.5C threshold means that by the year 2100, the world's average surface temperature will have risen to no more than 1.5C (2.7F) warmer than pre-industrial levels. quote:the International Panel on Climate Change uses a baseline of 1850-1900. That's because it's the earliest period with reliable, near-global measurements. It's true that some warming from human activity had already occurred by that point, because the industrial revolution began in the early 1700s. quote:The 1.5C target was based on assessments of the impacts of climate change at different levels of warming. For instance, the IPCC report found that at this temperature, extreme heat is significantly less common and intense in many parts of the world than at 2C. And at the other extreme, the coldest nights at high latitudes warm by around 4.5C when the world is at an average of 1.5C warming. That figure is especially important for the future of sea ice in the polar regions. At 2C warming, the coldest nights warm by around 6C. have we already exceeded 1.5C? not as a long term average but temporarily and locally, yes: quote:The global average daily temperature was more than 1.5C more than the preindustrial average for roughly one-third of days in 2023. Needless to say, this was a record number of days above the 1.5C daily limit. But there is a big difference between the global temperature on individual days, and the long-term average. The latter is what's meant when the 1.5C threshold is discussed in negotiations like COP28 we won't really be able to definitely say "we've done it" on a given day or even year: quote:Because the IPCC uses long-term averages for the global temperature, we will pass 1.5C warming on individual days, months and years before the decadal average is considered to be past 1.5C. are we on track? no: quote:Earlier in 2023, the IPCC calculated that by the mid-2030s there would be a 50% chance of the world commiting itself to a rise of 1.5C. However, a new analysis taking into account more recent data suggests we could reach this threshold sooner – as early as 2029. can we come back from an overshoot? hahahahaha: quote:To get back below 1.5C after overshoot would require carbon capture on a massive scale. [...] between 10 and 15 billion tonnes of carbon dioxide per year – that’s 3-4.5 times more than the EU’s total greenhouse gas emissions in 2021, and about 2-3 times the US’s emissions in the same year. and even if we managed to achieve this magic? quote:Even if we did return to temperatures under 1.5C after overshoot, many crucial systems would take centuries to return to a healthy state, including permafrost, sea levels, ice sheets and ocean acidity. and even if we didn't overshoot and just settled at 1.5C? quote:Given the extreme weather we are already seeing, some argue that 1.5C is not the final figure we should have in mind. so we should aim for 1C. how we doing? quote:At present, governments are already planning to produce more than double the amount of fossil fuels than would be compatible with a 1.5C pathway. quote:The UN's latest Emissions Gap report states that the world is on track for 3C of warming by the end of the century. oooof.

(https://www.carbonbrief.org/in-depth-qa-the-ipccs-sixth-assessment-report-on-climate-science/) ok the average might be higher but the tall whiskers are smaller so the apocalypse is cancelled  This was especially amusing because AR6 came on the heels of a bunch of CMIP6 models showing extremely high ECS values in the >5C range. However, because they failed to model some historical trends as well as other models that projected a lower ECS, their ECS results were discarded.

OIL PANIC posted:would love to learn more about these; google/ ddg have failed me. "partitioning and transmutation" seems to be good parlance for the topic, but it is crazy how much more lovely the internet has gotten for anything nuclear-related over just a few years too. that's probably true of everything else  but the short version is as you say: the solution requires reprocessing and enrichment, and that has been successfully painted as only for weapons and nothing else quick excerpt from an IAEA bulletin way back in '92: quote:The P&T [partitioning and transmutation] strategy can only be implemented by a fuel-cycle policy incorporating reprocessing as a key step through which all major actinides (uranium, plutonium) are recycled, and which is capable of isolating the minor actinides and some long-lived fission products from the effluent stream in order to prepare them for the subsequent transmutation steps.

i did some mowing yesterday in the early morning. humidity was 84% and the temp was, apparently, 31c. it felt a lot hotter than that, and it was truly an awful experience there were also no insects or birds around due to the heat which made it eerily quiet on a mid morning. so what is the threshold of insect heat resistance? how hot is too hot for bug?
