That looks a pretty good statistical fit to me considering the 'rules' say that a heating system has to cope with almost all the worse scenarios. As it is all at the lower end of the scale, a double of very little i.e. estimated at 10 to 30 MWh and the actual is 10 to 10 MWh seems pretty reasonable, especially considering that it includes DHW and I suspect most of the houses are larger, two occupancy places i.e. retired people.

From magic unicorn farts. Everyone that has invented 'free energy' thinks the laws of energy conservation are wrong.

It's (expletive deleted)ed, rip it out and cover it properly, with GRP.

I knew there was someone else. Think there is another person near there as well.

The stonewall crew you have in. Do they dress like this? They all look very strong.

Yes.

@Gone West west country then. Our @joe90 is just fleeing the area.

Not where I work. The average age is the same as the IQ.

That is when it becomes technology and engineering.

That is more to do with opportunity. So a socioeconomic problem, not a resource one. Except they are one of the few places (geographically) that can be independent of the rest of the world. If you had to design a country, it would look very similar to North America. Large plains that are suitable for agriculture, old mountain ranges that are good for mineral resources, newer mountain ranges that are good for geothermal energy, large, navigable rivers, good deep water ports, ample local fishing, the list goes on. Worth looking at this because you can see the per capita usage and the change in usage. https://ourworldindata.org/grapher/per-capita-energy-use?tab=table

Sheep cause huge environmental damage if left alone. As does algae. It is the balance of nature that is important, not the overall quantities. Earth can easily sustain 10bn+ people, just a case of getting the geographical and socioeconomic distribution correct. Like a coming ice age, the 50 year old Club of Rome's Limits to Growth has a lot to answer for.

Maybe the dots don't join up. A negative result is just a valid as a positive one, more o if you are looking for a positive one.

@Temp I want sea surface temperatures to drop. Then I can park easily without having to negotiate the Blue Tits, who seem to be more militant than the WI.

Just that, droplets. I cannot think of one case of a legionnaire outbreak that has not been caused by a cooling system, and a badly neglected cooling system at that. There was an outbreak in Aylesbury 20+years ago. Unmaintained A/C unit on the shopping centre. I used to stand by it during fag breaks.

Not as far f much has changed in that time. I have a feeling there is a newer report, but could not find it last night. Worth remembering that the technology is near enough the same, housing is similar, as are people. So still valid I think.

Only after publicly ignoring it for 40 years. There is a term put on those sorts, Woke.

Two things, 1. Betting, in its true sense is either a chaotic outcome, randomly picked from a known distribution, or predictable from fundamental physics. 2. I bet that talking does not sort it out.

Was that the same David Attenborough who was, in effect, a climate change denier until the last 12 years or so. Biology, geology and atmospheric chemistry do not have a 'master plan'. The COVID-19 pandemic was a symptom of poor industrial food production, easy travel between infected areas and non affected areas, very poor science understanding from world governments. The Earth, like us, carries the scares of its past. Entropy ensures that it will never return to what it was before, which is what worries me most about governments setting targets on such things as tree planting, bio-diversity, green spaces etc. Done with the best intentions, but usually misses the point. I get told off for posting up stuff, but bollocks to that, here is an interesting article about how fast, and effective, recolonization can happen. Environment Great Pacific Garbage Patch hosts stable community of coastal animals Arthropods and molluscs dwelling on plastic and other rubbish in the middle of the Pacific Ocean seem to be part of a new type of ecological community inadvertently created by humans By Madeleine Cuff 17 April 2023 Rubbish pulled from the Great Pacific Garbage Patch hosts a community of animals that normally live on coasts Citizen of the Planet/Alamy Stock Photo Coastal sea creatures have been found living and reproducing on the Great Pacific Garbage Patch, thousands of kilometres away from their natural habitat. The discovery could reshape our understanding of where coastal marine creatures can survive. The Great Pacific Garbage Patch is a vast collection of waste – much of it plastic – located between Hawaii and California, covering an estimated 1.6 million square kilometres of ocean. Researchers have previously found ocean-dwelling marine species living around the patch, but now it seems that coastal creatures have also established a permanent home there. Read more: The Great Pacific Garbage Patch is packed with floating life James Carlton at the Williams College and Mystic Seaport Museum in Connecticut and his colleagues collected 105 items of plastic waste from the garbage patch between November 2018 and January 2019. More than 70 per cent of the plastic items had evidence of coastal species living on them, with organisms including shrimp-like arthropods, sea anemones and molluscs identified. In fact, coastal species outnumbered pelagic species that live in the open sea by a ratio of 3 to 1, the team found. The coastal creatures seemed to be permanently living and reproducing on the plastic patch, says Carlton. “These are species that have rafted out with coastal debris and have now successfully found essentially a novel habitat out there,” he says.

Sign up to newsletter The discovery upends the assumption that coastal species couldn’t survive out in the open ocean and helps to solidify evidence that new types of ecological “neopelagic communities” are establishing themselves on plastic debris in the open ocean. “This has reset my thinking about how coastal species can survive in an environment in which they’ve not evolved,” says Carlton. We don’t yet know how this plastic ecosystem functions, including what the coastal creatures eat or how they interact with ocean-dwelling fish species. Carlton warns that floating communities like this one could pose a threat to coastal ecosystems. It has created a new epicentre of coastal species that could travel as invasive species into new coastal habitats, he says. “I would fully expect that as a result of this we will see more invasions of coastal zones,” he says. “This is a fascinating and important study,” says David Aldridge at the University of Cambridge. “It makes good sense that mass accumulations of plastic debris offshore can create artificial islands which support communities we would typically associate with coastal habitats. The authors rightly raise concerns about how these novel habitats can drive change in the wider ecology of the open ocean and assist in the spread of non-native species.” Journal reference Nature Ecology & Evolution DOI: 10.1038/s41559-023-01997-y

Like most predicative models, a number of scenarios are created, one or two of those scenarios showed extreme cooling, there were also scenarios that showed extreme heating. What then happens is that a probability of likelihood is attached, then all that data, along with the error bars, is plotted. That plot, along with other researchers work, is then plotted together, creating a distribution of likelihood (confidence intervals is statistical language). The readings in the middle are the ones that are most likely to happen, and the ones that tend to get ignored by the popular press and the public. There is not much news in saying that in a decade the whole Earth will be 0.1°C warmer, but it is a great story if it is projected to be 10°C cooler, or 8°C warmer, especially if you attach a label to it like 'ice age' or 'earth ablaze'. NASA has done some research looking into past models and how accurate they are. https://climate.nasa.gov/news/2943/study-confirms-climate-models-are-getting-future-warming-projections-right/ Below is a plot of the models that were run in 2004, easy to see how well the ensemble line (black) tracks the observed data (red) which is the yearly observations. You can also see that it (black line) does not get close to the upper and lower limits of the Confidence Intervals of all the models (the ensemble). The dip in the early 1990s is from a volcanic eruption, Mount Pinatubo. The models are designed to cater for this, though the actual date of the eruption is unknown until it happens, so is manually inputted. The important part though is that the 'recovery' time is not adjusted, that is the models doing there thing and predicting future temperatures. So let us, on here, not have anymore nonsense about the past prediction of a future ice age, the people researching it back then never said one was coming, so why should we.

What is wrong with this: "Equalise the retirement age for men and women at 63" Would suit me down to the ground.

There is reams of data and analysis about how well the MCS systems has worked here: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/606834/Report_on_compliance_with_MCS_installation_standards_v32.pdf And https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/606818/DECC_RHPP_161214_Final_Report_v1-13.pdf

Bit hard to tell what is what without seeing the problem in the flesh. As long as there is some ventilation that cannot bypass the insulation, and still does the job, you should be OK. Is that a cable in the top picture?

You need to atomise the infected water as well. A shower does not atomise like a cooling system.

No, what you are actually doing to misquoting and misunderstanding the research. Here is a very short summary. https://scienceblogs.com/gregladen/2013/06/04/the-1970s-ice-age-myth-and-time-magazine-covers-by-david-kirtley

I have rather skimmed most of the replies since my last reply. The IEE has some comments here: https://www.iea.org/reports/heat-pumps There is the Simon–Ehrlich wager regarding metal prices. Don't forget that the stone age did not end because of lack of stones. I don't think the world lacks the production capacity to make heat pumps, we make a lot of air conditioning units. Modern factories produce a lot more goods for less resources.
