  1. Make one of these. It will tell you how much power is being drawn and when. You can usually narrow down to what is causing it. Where about on the Atlantic coast are you?
  2. It will never taste the same either.
  3. Environment Analysis 14 November 2023 By Michael Le Page Will global warming continue even after we hit net-zero emissions? Understanding how the atmosphere responds to rising and falling carbon emissions is a complex business, and now researchers have found taking longer to reach net zero could see global warming continue afterward. When will global warming end? It is unclear The longer it takes to reach net zero, the greater the risk that global warming will continue for decades or millennia even after we have cut greenhouse gas emissions, according to an assessment by climate researchers. This means we may have to emit even less carbon dioxide than we thought if we want to limit warming to, say, 2°C, making carbon budgets even smaller than current estimates. “The timing at which we reach net zero is also key,” says Roland Séférian at the National Centre for Meteorological Research (CNRM) in France. Climate modellers once assumed that CO2 levels would remain roughly constant after emissions ceased. In such scenarios, the oceans would continue to warm for several decades, leading to further surface warming. But more than a decade ago, modellers realised that in fact the oceans will continue to soak up some of the extra CO2, leading to a gradual fall in atmospheric levels and less of the sun’s heat being retained. Recent climate models suggest that, by coincidence, this cooling effect balances out the ocean warming, meaning surface warming halts within a few years of emissions stopping. Not all climate models are the same, however. Standard climate models don’t include all feedbacks, such as how much carbon is taken up by plants on land. More comprehensive “Earth system” models suggest that if, say, emissions stop when the world is 2°C warmer than pre-industrial times, there is a 33 per cent chance that the planet would continue to warm past 2.3°C. Yet this is still not the full story. This is because even the Earth system models don’t include all feedbacks, such as the melting of the ice sheets on Greenland and Antarctica. He and his team have now done a comprehensive assessment of the uncertainties over timescales of decades, centuries and millennia. They looked at 26 factors that could lead to more warming or cooling, from the loss of forests and the melting of permafrost to shrinking ice sheets and changing ocean currents. For around a third of these factors, such as some cloud responses and the extent of sea ice loss, we have no firm knowledge and can only speculate, the researchers say. While some of the factors are expected to cause cooling, there is a general tendency towards additional warming, says team member Joeri Rogelj at Imperial College London. “Peak warming could be higher with additional impacts, damages and challenges,” he says. “It really means that reaching net zero becomes even more important as a milestone.” Additional warming doesn’t mean unstoppable warming, says Rogelj. It could be prevented by continued carbon removal after net zero, for instance. But in a comment accompanying the paper, Michael Mann at the University of Pennsylvania points out that carbon removal at the scale and speed required for halting warming might not be possible. “What is most urgently required is a rapid phaseout of human-induced activities that produce carbon pollution,” he writes. “I think this is an important paper that emphasises that our understanding of how much the world will warm or cool after we hit net zero is still uncertain,” says Zeke Hausfather of Berkeley Earth. “While our best estimate is that warming will stop when emissions stop, it’s also possible that the world might continue to modestly warm – or modestly cool – after net zero.” Journal reference Frontiers in Science DOI: 10.3389/fsci.2023.1170744
  4. Yes I did. Took 3 days to work out is was burning about 3 kWh a day. Crank case heater maybe. Warms the pump up if it has been idle too long.
  5. I think there is a misunderstanding about education and training. I like the example I learned during my teacher training from a rather pompous ex-army Major. "If your 12 year old daughter comes home from school and says they had a sex education class, you would not feel to concerned. If she came home and said they had sex training...." Apprenticeships, old and modern were about training and experience.
  6. How many reports of buildings being damaged, 10, 20, 100?
  7. Is lightning really a problem. Here is a small animation that shows how often it happens.
  8. How about a small fan, one from a PC maybe. https://www.amazon.co.uk/Dealikee-Brushless-120mmx25mm-Computer-Radiators/dp/B0BXWB9T85
  9. Octopus don't need pressure to stop something. Just look at all the great deals they have offered, most do not exist anymore. They are like a software company, they rush out the latest version, then let customers test it. Or to put it another way, let customers pay for the mistakes.
  10. Yes, and I am not criticising your work. The point is, that for every talented person, there are a lot more that are not skilled enough, do not care enough, and work for companies that are run by fraudsters (I worked for someone that would claim that his 'engineers' were all qualified plumbers, electricians, SEs or whatever needed to be said to get the sale or fob off an angry customer. He prided himself that he got a Physics 'O' Level by failing his Physics 'A' Level). Is that such a bad thing. Builders are modifying buildings that can cost upwards of £120,000, often £million. I have seen some dreadful treatment of staff in some companies. I was lucky that I was treated very well where I did my apprentice. Not so in all cases. In my current sector (catering), work place bullying is still very much accepted. It is not acceptable anywhere. I blame Gordon Ramsey who has made million out of being a horrible (expletive deleted) that likes to belittle everyone else. I don't know what the answer is to improve the attitude towards work and improve the level of skills needed. It is a hard job, some people just do not want to be told anything. They are the kind of person that if you offered them a tenner, they would refuse it because they would think there is a catch somewhere. They are also, in my experience, the type of people that prefer conspiracy theories and reality TV.
  11. Yes, and that is taught in the first 7 years of life (if you are a Methodist anyway). I found nd that a bit worrying. When I go for a meal, I like to know that the food safety standard are at a minimum at least. Does not mean that my fish allergy will vanish, but at least I know the fish will not have been kept, unfrozen for 14 days. I think there is a rather romantic notion about apprenticeships. The old master teaching the young pup all about life, the universe and everything. In reality, it is often forced upon a worker or college lecturer, just as it is forced upon a 16 year old, who may or may not be an entitled snowflake. I did an apprenticeship in toolmaking, job for life. I often mention toolmaking to people only a decade younger than me, and they don't have a clue what a tool is. Useless tools.
  12. Apprenticeships are very expensive. I just had a quick look at my local skills college and they do a Level 1, 1 year course in Carpentry, £1292. Electrical Installation Level 3 is £3345. Now level 1 is really for the functionally illiterate, and Level 3 is just a gnats above a GCSE. Now I know that 16 to 19 year olds get the education for free, except it is not really free, just comes out of general taxes. I am starting to think that a Science Degree is good value (no point commenting on an Arts or Humanities one as they are pretty poor value). Let us say that it cost, on average, £2k per course and you study for 3 years. My Hons Degree was 140 points, 120 ify them were actually needed. Each of the first two years was 7 subjects, so 14 in all, then the final year was 5 subjects and the project. So 20 in all If an apprentice does something similar but at a lower level, then £2k times 20 comes out at £40k. Similar price to a Science Degree. Except they are at a much lower academic level.
  13. And a weather forecast, though energy usage and weather are generally closely related.
  14. That is quite interesting as when I was studying climate change 15 years or so ago, Hungary was a case study for future weather extremes. Under any of the climate models, your part of Europe was going to get a lot hotter in the summer. As you are still at the design stage, are their things you can do to mitigate higher temperatures i.e. window shading, tree planting, body of water as a heat dump, PV on a roof and side walls (it can suck up 20% of the incidental solar energy). I lived on a 'tropical island' that often had sustained 35°C+ temperatures, luckily it was permanently windy, but large land masses do not have that affect. You may find Air to Air heating and cooling is better than slab heating/cooling.
  15. Could it be cross laminated timber, but with an additional veneer?
  16. Reminds me of all those happy summers with the family. Only 285 quids.
  17. To a certain extent yes, but there are some hopeless cases as well. This guy for instance. https://www.hvpmag.co.uk/Suspended-prison-sentence-for-prohibition-notice-breaking-plumber-/17105 Apparently he is now working as a motor vehicle fitted, possibly unqualified. It is usual to let the 'lad' in the garage change brake linings, as that is a simple job.
  18. You got your, matches, blow torch and some solder ready in case it leaks?
  19. Your wife things I am the Bull.
  20. I wonder how much of the poor workmanship is caused by the mismatch of building materials. Building have morphed from caves with a fire in them, via huts, to timber, steel, stone and brick building. In later years we have added heating systems, separate insulation, decentralised and centralised heating systems, better windows and doors, ventilation systems etc. Maybe because there is not any agreed standards for build standards and performance (even the Building Regs are open to a lot of interpretation) we have problems. When my neighbour was having his very expensive, though not particularily good, windows fitted, I started chatting to the fitter about air tightness tapes and why they were nto using any, "because it makes a house stuffy, I can't sleep in a room without the window open". "How about fitting proper ventilation" I suggested. I got a blank look. Maybe if he stopped wanking in bed he would sleep better.
  21. What, not even a Goblin.
  22. There are married women that work in catering. Though all the ones I have worked with recently are divorcees.
  23. I have run a few factories in the past. I would spend weeks with production engineers sorting out the logistics and manufacturing methods for a project. Train the workforce, then watch them work in the same slapdash fashion they preferred. Yes. One place I ran I introduced a shorter working week, but over 4 days instead of 5. 36 hours instead of 40 for the same money. The workers genuinely thought they would be working more hours for less money. (expletive deleted) the lot of them.
