  1. I don't think there is a prospect of large areas being ice free in the next few decades although the US President clearly supports the industries and activities that would make it happen sooner. Perhaps by the US "owning" Greenland, ongoing measurements of ice sheet loss could be heavily restricted? This coveting of Greenland by President Trump makes no real sense to me - or I expect, to Greenlanders and Danes. I expect it is a surprise and puzzle to Americans as well.
  2. I just became aware that the "greening" that had been observed prior to 1990 has reversed and plant growth decline, which is attributed to Vapour Pressure Deficit - the difference between the water vapor pressure at saturation and the actual water vapor pressure for a given temperature. Because the given temperature has risen. From the Yuan et al science paper - It does sound like the CO2 greening effect cannot be counted upon to provide beneficial outcomes for terrestrial plants.
  3. Dutchman - The mainstream science conclusions are sound; much more competent people than you or I have been all over climate science and again and again confirm the CO2 and warming connection. No matter whether called for by governments leaning Left or those leaning Right, no matter which nation's science institutions, the conclusion remains that we face a serious climate problem of immense proportions - due mostly to excessive fossil fuel burning. That is based on a good understanding of the underlying processes. We continue to learn more all the time, around the edges of understanding, that the Anything-But-CO2 crowd keep trying to nibble at in lieu of having any sound basis for rejecting the CO2 and climate connection. That includes recently establishing a link between mass mortality in the 1500's across the Americas, massive regrowth of forests and a drop in global CO2 levels of around 7ppm, contributing to the Little Ice Age. As did major volcanic eruptions in close succession, making a feedback loop from increased snow cover that lasted several decades. The closer we look at these kinds of past climate variations the more confirmation of the mainstream science view we get, not less. Which is consistent with that view being correct. I am not going to waste much more time on this - I will continue to trust those decades of top level expert advice and advocate for governments to make that advice the bottom line - and urge them to reject rather than encourage the kinds of pseudo expertise you espouse.
  4. Most limestones do get formed that way - corals, shelled and carbonate skeleton organisms becoming sedimentary rock - and they have taken up a lot of carbon. But whilst atmospheric CO2 levels have changed a lot over geological time the idea that it is on it's unstoppable way to below what plants need to survive has no basis at all - and in any case is irrelevant to the exceptional, mostly emissions driven climate change we facing now. We do know how and why the current global warming is happening with high levels of confidence and it doesn't include Solar Inertial Motion. The idea that there has been any serious science based doubt about the fundamental physical mechanisms since the 1980's has no basis. Whilst ordinarily people can believe or disbelieve what they like my own view is people holding positions of trust and responsibility turning aside from consistent top level expert advice are being negligent.
  5. There are misguided people saying the CO2 we are adding now is preventing a return of Glacial Maximum conditions in 10,000 - 40,000 years time. They actually look almost reasonable in comparison to this! Of course burning all the fossil fuels (a few hundred years worth?) will barely be a blip in the distant past by then - but here we are with the highest CO2 levels for 3 million years but we are supposed to keep burning fossil fuels (that won't last a thousand years of continuing use) for the next 5 million years and all plant life will die if we stop? And not worry about the global warming occurring because of the raised CO2 in the present? Sorry Dutchman - the only interesting question here is how anyone could think that could possibly be true. We get some bizarre notions popping up here but truly you have exceeded my expectations.
  6. I was keeping it simple, but yes, there is some small variation in sun-earth distances due to orbital motions being altered by other planets - but the principle point is the overall solar system barycentre most closely follows the Sun-Jupiter barycentre but the Earth most closely orbits the sun and that combined orbit moves around that Solar system barycentre (very close to Sun-Jupiter barycentre) without change to distances from Sun to Earth. However I am not an astrophysicist and and deferring to the expertise of others This paper got some discussion at and I will lift a comment from the host (who is an astronomer) there - No they are not. The Medieval Warm Period (or Roman or Little Ice Age) doesn't really present any problem for current best understanding of why our climate is currently warming - no matter that you and a small minority of pseudo experts may think otherwise; we've already far exceeded the temperatures during the MWP. Some "greening" does indeed appear a consequence of raised CO2 levels but so does raised temperatures - and depending on circumstances it will be other factors besides CO2 levels, including especially changes to rainfall and evaporation; I can assure you higher temperatures in places where dry conditions dominate (like where I live) mean less greening. No matter what conditions were like in the distant past it is the conditions that are recent, current and near future that matter - ie the period affecting people, agriculture, infrastructure and remnant ecosystems in the lifetimes of people now living. The claim that, without human emissions from fossil fuel burning atmospheric CO2 levels will drop to below that required for plant growth has no foundation; like everything else in this, it is the physical processes that matter - not blindly eyeing a graph and presuming a trend continues without physical processes that will make it continue. Do you think it is even possible keep burning fossil fuels for (going by the graph of declining CO2 provided) for the purpose of saving plant life for the next 5 million years? Utter nonsense! No, the Carbon Cycle will still be around and so will plants and CO2. I suggest you look to more reputable and non-partisan sources of information about climate change - such as the US National Academy of Sciences and UK's Royal Society. They draw on the world's most accomplished and respected scientists to review and make sense of complex science. I continue to urge politicians and governments to treat such advice seriously and not fall for the illusion that the current understanding of climate and how it changes is inconsistent or uncertain or in serious doubt.
  7. Not just those that have high confidence that global warming can be explained by atmospheric Greenhouse gases but astronomers and astrophysicists are disputing Zharkova's assertions. It appears that astrophysicists think what Zharkova is claiming violates some pretty basic orbital dynamics, which is then used to suggest that most of our warming is natural, in an over-simplistic as well as false manner. The main astrophysical problem appears to be the claim that the solar system barycentre - around which planets and sun orbit - moves as much as 0.2 AU (true) and that means the distance between the sun and Earth changes by that amount as a result, which is not true; the combined Sun-Earth orbit moves together by that amount, without altering the distance between Sun and Earth. It brings up an issue in common with all manner of proposed alternate explanations for global warming - they do not explain how raised CO2 levels DO NOT cause climate change. The "null hypothesis" idea gets thrown around a lot, without much examination but I suggest that, given what we know about this with high levels of confidence, CO2 rise resulting in warming has become the null hypothesis. ie you have to show how changes to GHG concentrations are not changing the heat balance of the atmosphere before any alternative explanation can be considered better.
  8. The value of correct prediction is very high - near priceless - but in the absence of scientific type methodologies, and given that humans not only have active imaginations but inexplicably, dream as well - rational prediction and irrational prophecy won't have any clear boundary. Without that clear boundary between prediction and prophecy any that turns out true can feel great - only I'm not sure they do feel the same; that absence of Reason in prophecy seems to give it more significance and an emotional impact that rational prediction does not. It seems to come with more frisson somehow. Which both sincere shamans seeking "truth" and charlatans, seeking power to influence would find significant.
  9. It has niggled at me how the use of prophecies within fiction works, because my own experience is that (despite no belief in prophecy in it's mystical rather than rational foresight forms) it does engage with my emotions and creates a sense of satisfaction when it is used. I've noticed how a lot of fiction plays on the satisfaction and even pleasure we get in seeing Bad People suffer - best of all if what happens looks like poetic justice, ie it is not actual commissions of violence that we dislike but violence without "good" cause, against those who we think do not deserve it. Our liking of violence against those we deem deserving of it makes a sort of sense in evolutionary terms - enabling people to overcome their inhibitions and use violence that would be destructive within their kin and tribe in defense of their kin and tribe - and it persists in us, despite it's often poor targeting (no weighing of facts and evidence is required to deem someone bad - it is an emotional judgement, not rational). In that light it makes a kind of sense, but why do prophetic elements in storylines come with a strong sense of satisfaction when they occur? Is there an evolutionary element to it like the use of "good" violence has? Off the top of my head I suspect correct prediction - of the rational foresight kind - is what this kind of response rewards emotionally and that had evolutionary advantage.
  10. I think there is real mind control - or at least strong opinion influencing and shaping - but it is through well known and proven means. It goes on to a large extent in plain sight - and gets treated as legal and legitimate .... Reducing access to critical information directly through censorship, commercial "in confidence" and non-disclosure contracts, indirectly through editorial interventions, ie burying it amongst distractions and diversion or failing to give it space. Advertising and PR and paid commentary to influence public opinion. Lobbying and Strategic Donating, Post political career inducements to influence political leaders. Tankthink to throw doubt on good information and provide academic sounding justifications for policy positions that are for the interests of their sponsors but harm the interests of others. I think there is plenty of scope for shaping people's opinions and responses without resort to "voice to skull using microwaves,scalar waves and ultrasonic " technologies.

    I don't know they get stopped by intelligence - very often, and very deliberately, it has the bad guy offered the opportunity to surrender but he is so crazy-bad he forces the good guys to shoot him - in self defense of course. Entire televisions series have contrived endings that result in a shootout, so the bad guy can be killed. The reality of messy aftermaths is almost never part of the story. My own view is that there is a universal human capacity for getting enjoyment and satisfaction from knowing someone deemed bad is made to suffer or die - but it does not require any weighing of evidence or certainty; just being told someone is bad can be enough. Just being like someone bad - the same religion, ethnicity, political associations or appearance even - can be enough. Our institutions and laws work to channel and moderate such urges, but entertainment too often plays upon them - we get shown how bad they are and after that we can enjoy seeing confessions beaten out the suspect or their premises searched without warrants and ultimately see them get shot and killed. I do think the style of entertainment reflects (with exaggeration) some real elements of the culture and vigilantism seems to be more celebrated by Americans than it is amongst, say Australians. Not that it doesn't exist here, but I don't think it has the same cultural approval. How many Americans are routinely carrying guns - and are on the lookout for opportunities to be a hero? Surely just carrying weapons requires an extra watchfulness for the people and situations that might warrant their use - but I really do prefer the idea that my society's armed protectors are well trained and resort to use of arms is not something random citizens are encouraged to do.
  12. Besides the multiple choices that involve other gods and religious doctrines, I mentioned "no-Heller" Christianity. Not even all Christians agree that eternal suffering is a possible outcome. And if a God really has expectations of us, He/She/It could make It's requirements inarguable by providing clarity and certainty. Meanwhile notions like fires, Earthquakes and floods are punishments for moral failures or lack of faith, and personal life achievements are attributed to God's favour remain widespread amongst many Christians - except of course when they are not. But I don't intend wasting more time on this argument.
  13. Would we really mine Asteroid gold in order to transfer it into vaults on Earth? The terrestrial gold market is more other worldly than the Asteroids are!
  14. Wulphstein - Pascals wager as presented is missing believing/not believing in Krishna, Odin, Zeus etc. Achieving/missing out on better re-birth rather than eternal joy/suffering should be considered, or not getting to Valhalla; it is a very narrowly Christian kind of question, with biases built in. Also I understand a lot of Christians are "no-Hellers", that do not promote any belief in eternal suffering as an outcome.
  15. This is a very good question - it is a real and serious concern that I (and I suppose, much better intellects than mine) have struggled to see solutions to. It may be that we (in "free democracies") never really have had independent courts or free and fair elections - but even the Highest judges and courts maintaining appearances of acting without fear or favour and the power of overwhelming majorities to vote out the appallingly bad (without resort to violent revolution) does moderate the very worst. It has to be very bad for revolution to look like a good thing - with far more likelihood of making things worse, including by overturning independence of courts; people who gain power by force rarely allow it to be taken away by courts. Sensei, I am not a fan of direct democracy, mostly due to your reason 2. I don't think mobs are intelligent and informed enough to do the jobs that good governance requires; the more people you put together the more simplistic the messaging gets - and, in practice, becomes more about pressing people's buttons to get reactions and less about engaging them with information and reason. I think good governance does require expertise - simply doing what people (unthinkingly) think they want, when what they want is highly dependent on the quality of messaging they are exposed to is not a good model. Looks to me like being deliberately baited with issues and examples that get reactions, not thoughtfulness are the rule in political messaging rather than the exception. Some kinds of requirements for Policymaking to engage more closely with Independent Expertise and limit power to simply ignore it comes to mind - our (sort of) independent institutions of science and learning are, like (sort of) independent courts of law are, I think, profoundly important institutions. I do think journalism and Mainstream News Media - that other important institutional element at work in democratic societies - are a pivot point with potential for making this problem of powerful incumbents shaping the rules better or worse. I'm not convinced the US model where freedom of "the press" is the freedom of press owners to pursue partisan political agendas, with little requirement for accuracy or truth, is a good one. (Who was it that predicted media organisations would one day replace political parties? It looks like some of these already ARE powerful incumbents that seek to reinforce their own power and privilege). Mostly the very business model media is built on - paid messaging intended to get people to buy stuff (and believe stuff and make voting choices) they otherwise wouldn't - looks too amoral to be a good foundation for democracy to rely on. But are elected political leaders even capable of regulating organisations with the power to turn elections? I'm doubtful. Even so I think that the regulating of media offers the greatest potential for putting roadblocks in the way of institutional corruption - and I think the greatest challenges to good governance are various forms of institutional corruption. Preventing corruption is more intrinsically important in my view than where governments and leaders and political parties and policies sit on any Left vs Right spectrum; the worst excesses of Capitalism as well as Socialism are, I think, more the consequences of corruption than ideology.
