  1. iNow I have not seen anything rebutting what I have said. The videos I have not been able to access might say something, but the attached summaries suggest otherwise. If you have a reference, then post it!!!
  2. In Iceland, there is the Deep Drilling Project, which aims to drill to a depth of up to 5 kms, both to obtain minerals, and for geothermal heat for power generation. http://www.iodp.org/iodp_journals/5_Progress_Report_on_Iceland_SD4.pdf
  3. Some facts to help understanding. 1. The Miller experiment. Now repeated many times with many variations. If you take a mixture of gases similar to what we believe the original atmosphere of Earth to be like, and pass strong energy through it, such as we would expect from lightning, ultraviolet, or meteor impact, then a wide range of organic molecules are formed, such as amino acids, purines etc. Deduction suggests that early rain will carry these molecules into puddles or lakes or the sea. Over millions of years, the concentration will build up into the 'primordial soup.' 2.
  4. Swansont That was because it did not need answering, and was irrelevent to the main point. Ice melts for a number of reasons, but the ice we see melting right now is doing so for reasons that have nothing to do with any hypothetical ice melt within the continent. For example ; melting due to contact with warmer ocean water cannot affect ice that is many kilometres inland. Ice sliding into the ocean is not a factor for most of Antarctica. The point I am making, and which you, Swansont, for some weird reason, see fit to deny, is that the vast bulk of the ice covering the continent
  5. Mokele, please.... No red herrings, please. What are the odds of a meteor that will melt Antarctica in the next 200 years? And there is no 'normal' process able to melt all of Antarctica's ice within 200 years. Actually, this debate is getting really weird. The catastrophist view is heading way out into never never land. There is absolutely no credible science to suggest that ALL the ice in Antarctica is likely to melt within 200 years. Even 1000 years would be a major stretch. How about you guys get your heads out of disaster fairy land and get back into the real worl
  6. Swansont You know better. Currently much of the sea ice disappears each summer due to the warming of the ocean. You are well aware that land ice is quite different. The ice at the fringe of Antarctica, close to the sea, such as that covering the Antarctic Pensinular, can melt for a host of reasons. However, that is not what I have been talking about. I have been talking about the ice that covers the bulk of Antarctica - the continent. It is 14 million square kilometres 98% covered with ice to an average depth of over 2 kms. http://en.wikipedia.org/wiki/Antarctica The vast bulk
  7. iNow I read the first couple of abstracts in your references. Nothing there about caloric restriction increasing human lifespan. The third reference talked of it reducing atherosclerosis. Fine. I agree. However, that simply reduces the chance of heart disease. It does not actually increase human life span. Human life span, by definition, is the length of life we get if we do not die prematurely. Such as by heart disease. The fourth reference was about biomarkers for predicting longevity. Again not relevent. I stopped at that point. iNow If you want to prove me wrong, find t
  8. iNow What I missed was putting in the extra words 'in humans'. Caloric restriction has been proved to work on a number of organisms, but has not yet been demonstrated to work in humans. I have doubts based on : 1. Lots of things work on other animals but do not work in humans, showing that over-generalisation can be misleading. 2. There are lots of human societies that already have diets that represent caloric restriction, but none have exceptionally long lifespans. Quite the opposite in most cases. In some cases, this will be due to nutrient deficiencies, but that should not be th
  9. iNow said : "At this point, I'm more than comfortable claiming that my point has been amply supported, and yours proven false." The reason you can say that is because we have not been arguing the same point. Or, as I said before, you misunderstood what I was saying. If you go back over the last few posts you will note that I was talking about the whole Antarctic ice field, which covers the entire continent. I stated that there was no way this was likely to melt within the next 200 years, and probably not within 1000, which is true. I admit that the 1000 year time span is mo
  10. iNow I have NEVER seen a proper scientific report predicting the melting of the entire Antarctic ice mass in the next 200 years. If you have such a thing, feel free to post it. Sure, lots of predictions of ice melt round the fringes, but the entire ice mass?? Uh uh! Swansont said, and I agree, that the Antarctic ice mass is sufficient to cause a 60 metre sea level rise if it all melted. Even James Hansen does not predict anything like that within 200 years. The maximum IPCC prediction is 1 metre by 2100AD. So, iNow, either you misunderstand what I am saying, or you have a ser
  11. Mokele I think you missed the point. The reason I have never seen such a report is that no such report exists. Climate scientists, even the disaster-mongers, do not believe that the vast bulk of ice in Antarctica is going to melt any time in the next few hundred years. Predicting ice melt around the fringes of the continent is one thing. Predicting the many kilometres thick ice in the centre at minus 50 C will melt. Well, if you believe that, how about the Loch Ness Monster??
  12. Swansont I have read a lot of material on global warming ideas. I have NEVER read any credible, grounded in science, account suggesting any sizeable fraction of the main, on land, ice mass of Antarctica will melt within 100 years. Everything I have read, that predicts melting, relates to the fringe of the continent, and especially the Antarctic Peninsular. The vast bulk of the land ice mass in Antarctica is not in danger of melting any time soon. Even Greenland, which is more at risk than Antarctica, will not melt, except at the fringes, for a long time to come. http://www.climatea
  13. iNow It appears that I cannot watch your reference. The link carried a message that it was not available to me since I lived outside the USA. I read the summary sections, and it appears that nothing there relates to the main part of Antarctica, which is what my last post was about. I repeat my message. There is no realistic chance that the vast bulk of the ice in Antarctica will melt any time in the next 100 years. Probably not any time in the next 1000. There is ice melt in the Antarctic Peninsular. However, that small part of the total appears to behave in terms of ice melt
  14. There are people who will try to suggest that Antarctica and Greenland are about to discharge their ice cover into the sea, and flood the world. In fact, that is extremely unlikely. Antarctica, for example, has an average temperature of minus 50 C. http://www.antarcticconnection.com/antarctic/weather/climate.shtml The biggest warming that has occurred in Antarctica has been on the Antarctic Peninsular, and amounts to less than 3 C. The rest of the continent has warmed to a level that is almost zero. To melt all the ice on Antarctica would require an enormous temperature increase.
  15. Cameron Lots of things have been claimed to reverse the ageing process. Caloric restriction. Blueberries. Wolfberries. Resveratrol. To date, there is not a single thing that has been proven by proper scientific study to actually do that. Of the unproven things, caloric restriction and resveratrol are probably the best candidates for something that might, in the future, be shown to have the power to slow ageing. However, it is still too early to accept that as correct. Watch the results of future research. In the mean time, there are a whole range of things which we know reduce y
