Matthew Syed ('The future will be cold and dark if we don't have a radical rethink', 7 August) has fallen for the hype over nuclear fusion. Experiments have only ever shown this to work for a few seconds; it looks like a bridge too far. If it did work, it would be very expensive.
There's no good reason to abandon nuclear fission reactors. In fact we should return to fast breeder reactors and burn all the surplus plutonium stocks. Nuclear waste is a trivial amount compare with all other waste and is safely handled.

Matthew Paris ('Show backbone on gay marriage, archbishop', p27 6 August) claimed that Jesus did not 'stare at his shoes and tell people how he empathised'.
When a woman accused of adultery was brought before him (Jn 8), Jesus merely stooped and wrote on the ground, apparently ignoring her accusers, who all then walked away. It looks as if he did empathise; he merely reproached her.
On homosexuality, note that Jesus was in love with his young disciples John (Jn 13;23).

You are right to claim that the Climate Apocalypse is coming unless if humanity continues to ignore the danger (Leader, 3 August). However, tinkering with minor problems and remedial measures will make little difference. Greenhouse gases continue to accumulate and would do so even if so-called 'net-zero' was reached. That would not reduce the amount of greenhouse gas; stronger steps are required to do that and there's no sign that anyone is willing to sacrifice their standard of living to do so. In fact, it's hard to imagine how civilisation could continue without its reliance on fossil fuels.
However, there is a way to get the global temperature down, even if the level of greenhouse gases remains high. That would require geoengineering. One solution is offered by Prof Steven Salter of The University of Edinburgh. He proposes to manipulate clouds, already a component in Earth's cooling system, to enhance their reflectance. By spraying seas water in fine droplets, more bright clouds can be produced (the smaller the droplets, the brighter the cloud). Prof Salter says that this brightening can moderate hurricanes and El Niño events, alter the gradient of the Indian Ocean dipole, save coral and cool sea water to increase the flow of oxygen to the deep ocean. Given enough time it can reverse rising sea levels. Precipitation can be varied in both directions. Work by Camilla Stjern at the Norwegian Cicero labs showed that it can introduce a trend of increased rain over drought-stricken regions with the reductions being over mid-ocean. Surprisingly little change in cloud brightness would be enough to accomplish this.
Prof Salter only lacks funding. He should be supported and encourage to save us from the Apocalypse.

Bob Ward claims that the impacts of global warming will continue to grow until we reach net-zero global emissions ('If you can't stand the heat...', 23 July)
Net-zero means balancing emissions against carbon sinks, a sensible strategy if the amount of carbon dioxide in the atmosphere were at the pre-industrial level of 280 parts/million (ppm). But at present the level is nearly 420 ppm. Net-zero with 420 ppm would still result in the global temperature rising, albeit more slowly. What is need to halt warming is a net-negative strategy (more sinks than emissions). However this is even less likely like to occur than net-zero; more drastic strategies need to be deployed.

The idea that Sir David King mentions: spraying seawater droplets to form 'bright white clouds' ('The scientists who are inventing a way out of climate change', 23 July) is actually that of Prof Steven Salter of the University of Edinburgh. It's called 'marine cloud brightening' as it can make bright clouds from small droplets (the brightness of clouds is inversely proportional to the size of the droplets).
So far it has not been tested due to lack of investment and support, but it may be the best way to halt global warming and could even reverse it.
Prof Salter says that marine cloud brightening can moderate hurricanes and El Niño events, alter the gradient of the Indian Ocean dipole, save coral and cool sea water to increase the flow of oxygen to the deep ocean. Given enough time it can reverse rising sea levels. Precipitation can be varied in both directions. Work by Camilla Stjern at the Norwegian Cicero labs showed a trend of increased rain over drought-stricken regions with the reductions being over mid-ocean.

Not for the first time I feel the need to explain that climate change will see the end of civilisation unless drastic action is taken to stop it.
Calls to reduce greenhouse gas emissions fall on deaf ears and, in any case, are ineffective--in this country anyway. The UK's contribution to global warming is trivial, as are any measures taken here to ameliorate it. But not even the big emitters like China and the USA are doing much; in fact China's are increasing.
There is talk of achieving 'net zero' (balancing emissions against carbon sinks), but don't be fooled. Firstly NZ will not be achieved; there are not enough sinks to balance the increasing emissions.
Secondly, even if achieved, NZ would merely stop more emissions than can be absorbed by sinks. That would still leave too much greenhouse gas in the atmosphere and the temperature would continue to rise. It would require a halt to all emissions to bring the global temperature down. Of course that in itself would probably mean the end of civilisation; life runs on exploiting fossil fuels.
That's a conundrum: to save civilisation we would need to destroy it! Is there no way out; no hope?
There is one. Global warming has two interacting causes: too much greenhouse gas in the atmosphere and insolation (solar radiation). If the gases can't be reduced then perhaps insolation can. People scorn geoengineering but in fact humanity is already unconsciously conducting a global experiment which is itself geoengineering.
A technical fix is needed to deal with a technical problem humanity created.
Sunshades in space or chemicals sprayed in the atmosphere have been suggested. But Prof. Steven Salter of the University of Edinburgh suggests using clouds to reflect more radiation than they do normally. He would make clouds more reflective. See reference to that scheme in my blog: Steuart Campbell Science Writer - Blog.
That at least would get the temperature down and give us more time to deal with greenhouse gas emissions and ocean acidification.
It's either that or were doomed.

The union of Scotland with England and Wales was achieved by agreement and the consent of the respective parliaments, creating a new joint parliament, each separate parliament voting itself out of existence.
That must mean that the future of Great Britain, now incorporated into the The United Kingdom of Great Britain and Northern Ireland, can only be determined by that joint parliament (Westminster). It is already agreed that constitutional matters are reserved to Westminster. They cannot be determined by a part of GB unilaterally.
The devolved Scottish Parliament may regard itself as representing a quasi-independent country but that is illusory. It cannot have the power to break up the UK any more than say Cornwall or Yorkshire or even Wales.
Consequently the question of whether or not Scotland should separate from England and Wales can only be determined by the Westminster Parliament, where there are representatives of both former states. So why is the Scottish Government not putting down independence motions in Westminster?

Dr Richard Dixon thinks that renewables and energy efficiency are all we need to keep the lights on ('No place for nuclear in our power plans', Special Report, 23 June)
Studies have shown that energy efficiency measures (mainly increased thermal insulation) do not result in less demand for electricity or gas. Beneficiaries of the increased insulation take the improvement in an increase in comfort, not lower fuel bills. In any case, too many houses in the UK have inadequate insulation, so improving it will take a long time. Meanwhile increased efficiency is theoretical rather than practical.
Renewable methods of generation electricity suffer from intermittency and so are unreliable. The National Electricity Grid requires reliability, which nuclear power can supply.
Dr Dixon points to defects in the Torness reactors, but this is irrelevant to replacement stations which do not have the same configuration. The AGR stations have supplied much-needed electricity since the 1980s.
He also point to the 'toxic legacy of radioactive waste to worry about for thousands of years'. This waste is not toxic, but it can be hazardous, depending on its grading. Only 1 per cent of waste is hazardous and that is carefully handled and stored. Perhaps Dr Dixon does not realise that the longer the half-life of a radioactive element, the less hazardous it is. Plutonium-239 has a half-life of about 24,000 years but it is safe to handle.
As for costs, they would not be so high if the 'linear no threshold' model of radioactive protection was not applied. This discredited model is responsible for much of the needless protection built into modern nuclear power plants. Low level radiation is not harmful. We live in a naturally radioactive environment. Anyway, if we want a reliable electricity supply, the generation of which does not cause greenhouse-gas emissions, we have to pay for it. Eschewing nuclear power is a form of national self-harm.

Tim Flinn floats the fanciful idea that we can live as energy after death (Letters, 20 June).
It is true that energy can neither be created nor destroyed, but it can dissipate. Humans gain energy from their food and, as a result of the conversion process; the average adult in typical indoor activities radiates energy at the rate of about 110 W.
When someone dies, the body will gradually cools, radiating away residual energy until it goes completely cold. The radiated energy is lost in the environment and is not available for life of any kind.

However, there is no certainty that this herbicide is harmful in the way implied. In fact one study undertaken for US Environmental Protection Agency showed that 'glyphosate does not interact with the pathways necessary to damage the endocrine system' as some have alleged. Nor has it been proved to be carcinogenic. The fact that someone contracts cancer while also being exposed to glyphosate is merely a correlation, not causation.
Ignorance of the effects of glyphosate is being hyped to conclude that it is dangerous to animals, including humans. This is not science.

'Life after death' makes as much sense as 'life before birth' (pace reincarnation). We live in our bodies and can't survive without them.
Nevertheless, Christians live in the hope they believe Jesus gave them. However, are they aware that the resurrected are to be sexless (Matt 22:30) and will live, not in heaven but on a reconstructed Earth where life is easy with no mountains, spending their time praising God for ever?

The Second Amendment includes the phrase: 'A well-regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed'. The framers of the clause adapted the wording of the amendment from nearly identical clauses in some of the original 13 state constitutions, who may have wanted to defend themselves against the federal government.
The clause might have been intended to mean that the people could arrange to have Militias, like the modern National Guard, for their own protection and it might not have been intended to allow every citizen to have weapons of their own. But, unfortunately, that's how it has been interpreted.

Andrew HN Gray claims that modern Christianity is a product of the Enlightenment and is itself 'modern, liberal and progressive...[leaving]...humanism looking rather pointless' (Letter[s], 1 June).
His argument has a lot of holes. Firstly, the Enlightenment emphasised reason and individualism rather than tradition, undermining the tenets of the Church. It's roots lay in the humanism (sic) of the Renaissance and it led to rational and empirical methods of discovering truth by scientific methods.
In particular it allowed the Bible to be accessible to the laity in their own language. This led to criticism by deists who propounded a natural religion without revelation or miracles. Furthermore, astronomy destroyed the Biblical cosmology while geology destroyed the Biblical creation account and ridiculed the chronology of the Old Testament. So is Mr Gray's Christianity one where most of the Bible is of doubtful veracity?
Nietzsche regarded Christianity as 'decadent'. It is certainly in decline in progressive and enlightened countries. More and more people, in the UK anyway, reject religion, especially Christianity. Perhaps Christianity is now so 'liberal' that one can believe anything. Is that 'progressive'? It appears that it is Christianity, not humanism, that is 'pointless'.

She is not even the second of England, as the UK is a different country, formed in 1800 from the union of Great Britain and Ireland. Consequently, Elizabeth should not have been given any regnal number, being the first of that name for the UK. The UK's first monarch was George III.

Otto Inglis claims that the greatest cause of climate change is 'variation in the sun's energy output' (Letter, 21 May). He also refers to the 'hysteria' over the issue and evidently believes that global warming is merely a natural fluctuation.
The Sun's output does vary as it goes through an 11-year sunspot cycle. However this variation is too small to have much effect on global warming, which is mainly driven by the increasing level of CO2 in the atmosphere.
Mr Inglis calls for 'science grounded in observation, common sense, mathematics and, above all, integrity'. That's precisely what the International Committee on Climate Change has been doing. So it's disappointing that dinosaurs like Mr Inglis prefer to ignore it and put their faith in myths.

However, a close Yes result vote with about half the voters against independence would be more than unsatisfactory; it could cause extreme bitterness and strife.
The only way to hold a meaningful and acceptable result is to require a two-thirds majority for change. After all the SNP could not change their own constitution without such a majority. What's good enough for them is surely good enough for Scotland.

Dr Andy Steiger thinks that he owes nothing to a 'meaningless universe' ('If you care about the planet, invite God into your thinking', 19 May). Instead, he thinks belief in God alone justifies care for the environment and gives meaning to life.
However, we don't need belief in an invisible deity to know that we need to care for and fix our environment. The reason being that, if we want humanity to survive (I take that as given), we owe it to future generations. We are here by lucky chance on this planet, probably the only one in this Galaxy with intelligent life. So we also have a duty to survive and make the most of the situation in which we find ourselves. It would be a shame to so ruin the planet that human life becomes impossible. Unfortunately it looks as if we will. What would Dr Steiger's god think about that?
Dr Andy Steiger thinks that he owes nothing to a 'meaningless universe' ('If you care about the planet, invite God into your thinking', 19 May). Instead, he thinks belief in God alone justifies care for the environment and gives meaning to life.
However, we don't need belief in an invisible deity to know that we need to care for and fix our environment. The reason being that, if we want humanity to survive (I take that as given), we owe it to future generations.

Mary Thomas (Letter, 13 May) says that, in my letter of 12 May I am wrong about 'Scottish taxpayers' subsidy for nuclear power'. However, in that letter, I said no such thing; I merely corrected Frances Scott's claim (Letter, 9 May) that UK taxpayers are funding the construction of Hinkley Point C. So far, nuclear power in the UK, unlike wind power, has never been subsidised by taxpayers, either in construction or operation.
If the proposed funding of Sizewell C proceeds that will the first time that UK taxpayers pay toward the construction of a UK nuclear power station. This is welcome; funding by governments is cheaper than for private companies and it is the duty of governments to ensure that reliable electricity is available to consumers. Nuclear power provides that reliability. Scotland needs nuclear power as much as England; the Scottish Government should drop its unreasonable objection to it.

According to Prof Declan Diver ('Government urged to back bid for world's first fusion power plant', 15 May), a nuclear fusion plant would be 'switched on when the weather's bad or when you can't run your wind power or at night time'.
Electricity from a fusion plant, if it works, will be expensive enough but making it an intermittent (back-up) generator would make it even more expensive. Nuclear fission stations are most efficient as base-load generators operating almost continuously. That must also apply to any future fusion stations.

Frances Scott claimed that Hinkley (sic) Point C, the new nuclear power station being built in Somerset, is one of several major projects in England funded by UK taxpayers, including those in Scotland (Letter, 9 May).
She is [They are] mistaken. This project is funded by EDF (Électricité de France) and CGN (China General Nuclear Power Group). In effect it is being funded by French and Chinese taxpayers.
Moreover, its cost overrun is estimated to be £2.9bn, not £5bn and it has yet to be determined how delayed the completion will be.

The census referred to in Luke 2:1, was actually a local Judean census conducted by Rome which had taken direct rule of the province in CE 6 after ejecting its Herodian king. Herod the Great had been dead for 10 years. Moreover it did not involved the widespread movement of the population implied by Matthew and Luke or the travels of the 'holy family' (the latter were invented).

You are [The Scotsman is] right to draw attention to the creeping climate emergency ('Signal fires of emergency', 29 April).
While our immediate attention is on a European war and lingering Covid-19 effects, the existential global threat is outlined by the latest IPCC report. This concludes that, if emissions continue at the present rate, the global temperature will have increased by 1.5 degC [degrees centigrade] above pre-industrial levels between 2030 and 2052. It warns that warming from anthropogenic emissions will persist for centuries to millennia and will continue to cause further long-term changes in the climate system, such as sea level rise and ocean acidification, with associated impacts. There will also be climate-related risks to health, livelihoods, food security, water supply, human security and economic growth. An increase of 2 degC will make it all worse.
Do you wonder what would happen if steps are not taken to curb global heating in the long run? If you are not of a nervous disposition read Mark Lynas's book Our Final Warning, Six Degrees of Climate Emergency (2020). He takes the reader through all 6[six] degrees of heating and spells out the dire results of each. He notes that, according to the IPCC, an increase of 6 degrees in only 100 years is 'plausible'. That could see the end of civilisation.
It has become clear that attempts of reduce damaging emissions are largely ineffective worldwide. Emissions continue apace with the CO2 level in air reaching 419 parts per million (the pre-industrial level was 280). It could reach 500.
There is only one way to save planet Earth from becoming an uninhabitable hothouse and that is to screen us from the sun's heat. Several geoengineering projects have been suggested but rejected by people who think, naively, that emissions can be reduced. One or more of these methods is urgently needed.

But there is no evidence that God sent him, nor is the gospel record clear on resurrection (see John 21, an addendum chapter in which the disciples were not even sure that they met their master).

There is concern regarding land ownership in Scotland, with about half of all rural land in private hands, some foreign.
In 1840, French anarchist Pierre-Joseph Proudhon claimed that 'Property is theft'. In a way, he was right. Originally the first owner of a parcel of land must have appropriated it, i.e.[that is] staked a claim to it. All subsequent owners base their rights to the land on that first claim.
It is reasonable therefore to believe that no one has any basic right to own any land in Scotland; it should be owned on behalf of everyone by the state and occupiers should pay to occupy it.
How can such a situation be achieved? Could the state step in every time property is sold and claim ownership of the land (not anything built or growing on it)? Would the state have to buy the land?
People could be allowed to occupy land provided they pay a Land Valuation Tax to the appropriate local authority acting as an agent for the state. This would do away with the unfair Council Tax. What people do with the land would still be subject to planning law.
Is this 'pie in the sky' or a realistic solution to the land ownership problem?

The SNP's existential opposition to nuclear power has always been a puzzle to me. It seems to go back to the time when Jack McConnell, as first minister, declared Labour against nuclear power on the basis that no one knew what to do with the radioactive waste. In fact this was mistaken. The nuclear industry handles its waste better and more safely than any other industry and the route to storage and disposal is well established. No one has ever been harmed by radioactive waste but many have been harmed by the waste from traditional power generation.
I conclude that opposition to nuclear power stems from ignorance and prejudice. Uranium, created in exploding stars, has the highest energy density of any fuel and few uses except for power generation (pace nuclear weapons). Luckily humans found a way to exploit its potential for providing continuous electricity without harmful emissions. Just the fuel we need to power our way through global warming. There is no shortage of uranium (it can even be extracted from seawater); rather than being mined, it and some plutonium can be reclaimed from the 'used fuel' burned in reactors. Better use of it and the plutonium could be made through the use of fast reactors like the prototypes developed at Dounreay. These reactors can even make new fuel from non-fissile uranium-238. It is even possible to burn radioactive waste (fission products) in a reactor such that little real waste remains. I hear nothing from the UK government about fast reactors, which operate in several other developed countries.
The Scottish Government appears to have no valid reason for its opposition, except perhaps that it is against any Westminster policy. Nevertheless, Scotland will eventually have to import nuclear-powered electricity as its obsession with renewables leads to blackouts.

John F Robins (Letter, 27 February) should note that highly-radioactive waste will not be kept at Sellafield for 5700 years. Eventually it will all go to a deep geological repository like those already under construction in Sweden and Finland.
Any deaths from the Windscale or Chernobyl are irrelevant to consideration of modern UK nuclear reactors, whose safety record is excellent. Scaremongering about radioactivity is unhelpful and misleading.
Excess electricity can be stored as potential energy in pumped storage hydro schemes but can be used afterwards to generate power only for a short time: less than a day in the case of Cruachan. Since generation stops twice a day as the tide turns, tidal power is unreliable. Only nuclear generation is reliable. Calling it 'very dangerous' and 'expensive' is sheer mudslinging from ignorance.

Your claim that warm air holds more moisture (19 February) is a colloquial myth. At best its a metaphor for what happens but is misleading.
Air does not 'hold' water. If there were no air above a water surface, water molecules would still evaporate and form a vapour by themselves.
Warm air often has more water (vapour) molecules than cooler air because of the energy level of the water molecules. When air is warmed the water molecules are also warmed giving them more energy. Therefore warm air, which is filled with highly-energised water molecules, often contains more water molecules, but it doesn't 'hold' them.

Therefore warm air, which is filled with highly-energised water molecules, often contains more water molecules, but it doesn't 'hold' them.

If Baroness Dr Ros Altmann claimed that the UK would continue to pay Scottish pensions after independence (quoted by Mary Thomas in her letter of 17 February), Altmann [she] must have overlooked that fact that independence for Scotland breaks up the historic Great Britain and, consequently, the UK.
If the UK no longer exists it cannot continue to pay any pensions. Pensions would be the responsibility of the successor states: Scotland and what's left of the UK (what would one call it? EWNI?). Those states would also be responsible for paying pensions to their own expats.

John F Robins mistakenly thinks nuclear power plants are 'tools of mass destruction' (Letters. 13 February).
1) He thinks radioactive waste remains 'lethal for over 50,000 years'. Few fission products have a half-life ('HL': the time taken for activity to halve) that long. It is also simplistic as the different elements in the waste have different half-lives . Moreover, the longer the half-life the less radioactive the elements is, e.g. Plutonium-239 has an HL of 24,000 years but its low radioactivity means it is safe to handle. The dangerous fission products are things like Samarium-151 (HL 90 years). The total radioactivity of a mixture of pure fission products decreases rapidly for the first several hundred years before stabilizing at a low level that changes little for hundreds of thousands of years. In any case, fission products constitute only about 3 per cent of all radioactive waste from a power reactor. Most waste is far less radioactive.
2) It's not true that no one knows how to store and manage radioactive waste (not just from nuclear power but from industry and medicine). The waste has been handled safely at Sellafield since 1965. It sends low-level waste to disposal at Drigg and holds the high-level waste until a geological disposal facility is built. Plans are in hand for the latter. There is no limit to the amount of such waste that could be stored until it becomes harmless.
3) It's hard to see how a nuclear power station could be any use to a terrorist. The stations have armed guards and what could a terrorist do to it anyway? Nuclear power station in the UK cannot explode.
4) The accidents Mr Robins mentions are irrelevant to the UK nuclear power programme. The Windscale fire was not in a power station; the accident at Three Mile Island was due to a ventilation fault and harmed no one; Chernobyl was a type of reactor that has been built nowhere else in the world and would not have gained approval in the UK, those who died where mainly fire-fighters; Fukushima was not an accident in the power station but the result of a tsunami that overwhelmed pumps, only one worker was harmed.
Exaggerating the defects of nuclear power is not a rational argument against its use. If the alternative is a lack of electricity then its an option that needs to be considered.

You claim that 'climate change' (it's really 'global warming' and even that term understates the matter) is 'far too important an issue to be co-opted and subsumed into a relatively petty and parochial dispute on these islands. It's much, much more than a potential source of grievance politics.' (Leader, 10 February)
True but anything we do on 'these islands' will be trivial in comparison to the huge task facing humanity. Action is needed on a global scale by international bodies and anything we do is a distraction from the global effort required.
While greenhouse gas emissions continue to increase, there is little hope of any country, particularly not the USA or China, getting them down enough to even halt emissions. 'Net Zero' will probably not be reached and, even if it were, that's not enough to halt runaway global warming. The only effective way to get control of the climate now is through some sort of geoengineering (shading us from the sun), but who is going to organise it?
If the world does not organise that, our civilisation is doomed.

Apart from their huge cost [outlined by (]Clark Cross's l[(L]etter, 5 February), heat pumps have defects. Unless installed as a house is built, when the cost is lower, they are difficult to install. The installation process means significant work and disruption to the house, and garden if it is a ground-source heat pump. Some heat pumps experience trouble in cold area which can damage the system and mean that in winter full efficiency cannot be reached. Some of the fluids used for the heat transfer are of questionable sustainability and raise environmental concern.
Air-source heat pumps are less efficient than ground-source and may not achieve the required temperatures. They may need to operate longer and radiators may need to be changed to larger sizes. Also they would need servicing every two years. Heat pumps cannot provide hot water; electricity will be required.
Since heat-pumps and water heating use electricity, one wonders if there will be enough available, what with transport going electric. I wouldn't want one.
Why is the UK going to all this trouble when the planet is not going to notice the UK's trivial contribution? We will be 'cutting off our nose to spite our face'!
It would be better and simpler to hydrogenise the gas grid.

Sarah Baillie claimed that 'Scotland now meets [all?] its electricity needs from renewables' ('A turning point on road to net zero', [Friends of the Scotsman], 31 January).
This is both incorrect and misleading. Almost every consumer of electricity in Great Britain (GB) receives power from the National (Electricity) Grid which is fed by various generators. As I write, only 50.8 per cent derives from renewables; 33.4 from burning fossil fuels and 15.7 per cent from low carbon sources. The latter will include nuclear power with some solar.
Consumers in Scotland are not isolated; we get the same electricity as the rest of GB [the UK]. Nor, contrary to what some companies claim, can the source of the electricity we received be identified as coming from a particular generation source.

MSP Liam Kerr did well to explode the myth that nuclear power is expensive but then claims that onshore wind farms are 'part of the solution' ('SNP is wrong to pour scorn on a move to low-carbon nuclear', 28 January).
Nuclear power provides clean base-load electricity but cannot cope with daily variations in demand. Nor can unreliable wind farms; they are not the partner than nuclear requires to keep the electricity grid stable.
Gas turbines can meet the excess demand but they burn a fossil fuel. Pumped storage can meet a short term hike in demand but there is not enough of it. Tidal power is reliable and might be used for this purpose but again there is too little. Imports and battery storage might be considered. What would be the best partner for nuclear to keep the lights on without damaging the atmosphere?

I was astounded to see Susan FG Forde (Letters, 21 January) calling for pumped storage hydro stations to run 'all the time'. Does she not understand that such schemes can only run until their top reservoir is empty, after which they need to take electricity from the grid to pump water back up to the reservoir. The Cruachan station can only run for 22 hours at a time. Even then it is required to keep enough water to run for 12-hours should the grid require a 'black start' after collapse.
The only other major pumped storage station in Scotland is that at Foyers on Loch Ness, which is actually combined pumped storage and conventional hydro. There are other smaller stations.
Originally designed to take surplus night-time electricity from nuclear power stations, pumped storage can now take surplus electricity from wind farms. However their total contribution to the grid is marginal.

Will retrofitting every UK home tackle climate change ('It's as serious as the blitz', Home 16 January)? If that means 'will it make any difference to global warming?' then the answer is 'No'!
Every home should be properly insulated if only for comfort and economy, but even if every home in the world were so insulated, it would make little difference to our warming planet. So why does Insulate Britain think it would? Anything the the UK does is trivial on a global scale.
In any case, how does IB think it would work? A lot of electricity now comes from generation methods (renewables, nuclear, etc) that do not emit greenhouse gases. Heating by gas should be replaced by burning hydrogen. Campaign for that and more nuclear power instead.

Tim Flinn (Letters, 10 January) claims that nuclear power is 'the most...expensive domestic fuel in regular use'. I should like to see his justification for that claim as several international studies have shown that this is not the case. In 2014, the US Energy Information Administration concluded that the levelised cost of electricity from new nuclear stations was 96$/megawatt-hour, between that from natural gas at $64.4 and solar power at $130. Mr Flinn should also know that the cost of nuclear power includes the decommissioning of the plant: the money being secured in the Nuclear Liabilities Fund. In 2009, the Fund was valued at £8.3 billion.
As for so-called 'nuclear waste', most of it is used fuel rods which mostly contained unused uranium with a bit of plutonium and fission products. There is also a lot of not very dangerous low-level waste from contaminated items. The uranium and plutonium can be recycled although there seem to be no plans to do so. Recycling used fuel could produce hundreds of years of energy from just the uranium. Plutonium could provide energy in fast reactors for a thousand years, creating new fuel in the process.
The fuel rods are taken to Sellafield for storage. This unique UK facility costs about £3 billion/year but is forecast to generate about £5.7 billion between 2018 and 2028 from UK and overseas contracts.
Mr Flinn also claims that nuclear fuel is toxic (an inappropriate term as it relates to poisons) and the waste 'deadly'. The only danger from nuclear fuel and waste is ionising radioactivity, which mainly depends on the half-life. Uranium and plutonium, have such long half-lives that they be handled safely. A kilogram of uranium emits about one third of that from a medical radioisotope. Even a household smoke detectors emit radiation as does our environment and some of our food. The fission products from nuclear activity are only 'deadly' if mishandled and improperly shielded.
Mr Flinn should tell us how we will maintain a reliable supply of electricity and safeguard the environment without nuclear power generation. We cannot rely on renewable generation. If the alternative is power blackouts then the price of generation from nuclear energy is irrelevant and we must meet any cost of waste disposal.

He is wasting everyone's time. Some issues are controversial, justifying comments on both sides, but global warming is not one of them. It is the most serious and urgent problem facing humanity without, at present, any sign of being ameliorated.
Do you not accept the scientific consensus, represented by the (UN) International Panel on Climate Change (IPCC) which has made it clear that global warming is due to anthropogenic greenhouse gas emissions over at least the last century and a half.

Charles Wardrop is obsessed with the idea that climate change is solely due to solar activity and that CO2 is not responsible (Letter, 6 January).
Certainly the sun is vital to all life on Earth and it is responsible for global warming insofar as it provides the heat that greenhouse gases allow. CO2 and methane combine with increased water vapour, also a greenhouse gas, to raise the Earth's temperature. However, we have released too much CO2 and driven the temperature up beyond the normal level. This will continue until we do something to halt the rise. Without preventative action in the next century the Earth will become uninhabitable, an unbearable hothouse.
It's not the sun that has brought this situation about; it's mankind's irresponsible burning of fossil fuels and the release of uncontrolled CO2. It is we who are in control.

Whoohoo! Jesus is two thousand and twenty-two years old, or so Christians believe and we all sort of acknowledge that in our year numbering system. However, anyone who believes that he is still alive needs a reality check.
The evidence in the gospels is that Jesus died during crucifixion, but not from it, in 33. Told that he was dead after only a few hours, a suspicious Roman guard speared him with his lance (see John 19:33-5). Jesus could not have survived that and, pace some superstitious stories, he was not seen again.
Whoohoo! Jesus is two thousand and twenty-two years old, or so Christians believe and we all sort of acknowledge that in our year numbering system. However, anyone who believes that he is still alive needs a reality check.
The evidence in the gospels is that Jesus died during crucifixion, but not from it, in 33. Told that he was dead after only a few hours, a suspicious Roman guard speared him with his lance (see John 19:33-5). Jesus could not have survived that and, pace some superstitious stories, he was not seen again.

It's bad enough to see Russel Grant's 'Your stars' every day but now you've printed two whole pages of 'Predictions for the year ahead' (1 January).
Surely you know that there is no scientific basis for astrology and that people can be misled about their future. I read my mine and found it completely irrelevant. I urge you to abandon this practice and, if you won't, at least add a warning that such predictions are entirely speculative and random.
