Nuclear must be part of the low-carbon mix | Letters
Re David Lowry’s criticisms of nuclear energy (Letters, 17 September), it is true that nuclear plants stop generating temporarily for maintenance and repair, but the same is true for most other forms of electricity generation. However, on average these outages represent a much smaller quantity of lost generation compared to the day-to-day intermittency of wind or solar. Nuclear plants spend a high proportion of the time generating at their maximum capacity.
On emissions, some proponents of both nuclear and renewables do fall into the habit of referring to their technologies as “zero-carbon”, even though there are some greenhouse gas emissions produced with all forms of generation. But there is remarkable academic agreement that the emissions from nuclear, wind, solar and many other non-fossil generation sources are similarly low per unit of electricity generated and these emissions are tiny fractions of those associated with burning coal and gas. We desperately need to cut emissions in our electricity mix to as low as possible.

Perhaps it is no coincidence that the record-breaking fatberg was discovered during a week of coordinated nationwide beach clean-ups, run by volunteers (Monster fatberg found inside London sewer, 13 September). Fatbergs like the “monster” found in Whitechapel could easily be avoided, but it’s time for an honest discussion about the causes. It’s not just cooking oil but a range of other items that we flush down our loos.
Tampons are widely believed to be flushable but swell up in sewers, combining with oil to create impenetrable blockages. Blocked sewers overflow into rivers, leading to the oceans, hence the huge clean-ups needed every year to rid our beaches of so-called sanitary waste. We can’t address this until we’re prepared to use the word “tampon” in discussing the problem. Five of the major UK water companies give out free FabLittleBag disposal bags to householders as a crucial preventative measure. We hope Thames Water will join them to save millions in costly repairs – which is passed on in our water bills – as well as to prevent the horrific aquatic pollution.

Ministers launch taskforce to help boost green business investment
Green Finance Taskforce, which will be led by investors and leading figures from the City, will find ways to aid the UK’s shift to a low-carbon economy
A new group led by investors and leading figures from the City of London has been brought together by the government to draw up measures to encourage “green finance” in the UK.
The Green Finance Taskforce will have six months to come up with proposals on how to increase investment in the low-carbon economy and will work with banks and other financial institutions. Chaired by Sir Roger Gifford, former lord mayor of London, the taskforce will look at measures to make the UK’s planned investments in infrastructure, for instance on energy and transport, more environmentally sustainable.

Gary Cohn confirmed the US intends to withdraw from the agreement without a renegotiation, but declined to provide details
President Donald Trump’s top economic adviser said at the United Nations on Monday the US has not changed its plans to withdraw from the Paris climate pact without a renegotiation favorable to Washington, a step for which there is little appetite in the international community.

Goal to limit warming to 1.5C to avoid the worst impacts of climate change was seen as unreachable, but updated research suggests it could be met if strong action is taken
The highly ambitious aim of limiting global warming to less than 1.5C remains in reach, a new scientific analysis shows.
The 1.5C target was set as an aspiration by the global Paris climate change deal in 2015 to limit the damage wreaked by extreme weather and sea level rise.

If animals are our other, there is nothing quite so other as the octopus. It is the alien with whom we share our planet, a coeval evolutionary life form whose slithery slipperiness and more than the requisite number of limbs (each of which contains its own “brain”) symbolise the dark mystery and fear of the deep.
Now comes news that octopuses have been building their own cities down there. In a story straight out of James Cameron’s The Abyss, scientists have discovered that the wonderfully named “gloomy octopus”, octopus tetricus, are not the loners we once thought them to be.

Study finds excessive levels of the metal, which can seriously harm unborn children, in women from Alaska to Indonesia, due to gold mining, industrial pollution and fish-rich diets
Women of childbearing age from around the world have been found to have high levels of mercury, a potent neurotoxin which can seriously harm unborn children.
The new study, the largest to date, covered 25 of the countries with the highest risk and found excessive levels of the toxic metal in women from Alaska to Chile and Indonesia to Kenya. Women in the Pacific islands were the most pervasively contaminated. This results from their reliance on eating fish, which concentrate the mercury pollution found across the world’s oceans and much of which originates from coal burning.

For centuries, humans have championed the democratic political system. But can it facilitate the radical change needed to stop the potentially annihilating effects of climate change?
Although individual action to protect the environment – consuming less, recycling more, reducing one’s carbon footprint – might be a contribution if enough people did it, the battle to minimise human-induced climate change has to be a worldwide endeavour among cooperating states. The outcome of the 2015 UN Climate Change Conference was one of the most optimistic and encouraging steps hitherto achieved in that battle – that is, until Donald Trump said he intended to withdraw the US, the biggest climate polluter in history, from the agreement. The Paris agreement and President Trump’s decision illustrate the two ends of the spectrum of effort and concern. Our planet cannot be protected from a warming atmosphere – with melting ice caps, rising sea levels, droughts, floods, famines and migrations of desperate populations – without vigorous joint effort by the world’s states.

Climate models have an even better track record than the weather models that saved lives in Texas and Florida
The impacts of hurricanes Harvey and Irma were blunted because we saw them coming. Weather models accurately predicted the hurricane paths and anticipated their extreme intensities days in advance. This allowed millions of Floridians to evacuate the state, sparing countless lives.
Some contrarians have tried to downplay the rising costs of landfalling hurricanes by claiming they’re only more expensive because there are now more people living along the coasts with more expensive stuff vulnerable to hurricane damages. However, those arguments fail to account for our ability to predict hurricane tracks earlier and more accurately by using better and better scientific models. We’re able to prepare for hurricanes much better today than in the past because we have more warning.

The Sphinx is the closest Britain comes to having a glacier. It has disappeared just six times in the last 300 years, but this year it is almost gone. Murdo MacLeod joins snow expert Iain Cameron to study the state of Scotland’s permanent snow
“It’s a very sorry sight,” says Iain Cameron. It is late August and we are standing in front of Scotland’s very own Sphinx. It never had claws, paws, nor a mysterious countenance, but if it once had they would have melted away, just as the rest is about to do. “Grim,” says Cameron with gravel in his tone. “It’s pretty much in its death throes.”

Sunderland Point, Lancaster At the river’s edge, retinues of curlew, lapwing and redshank assembled and lifted again, landing in each other’s wake
Even as Margaret Owen pulled on her fishing “yallers”, we knew there was little chance of a salmon. I had been waiting for weeks to see Margaret in action, but the salmon simply haven’t returned to the river Lune this year, and the season was about to end.

Fish, which is endemic to Tasmania, was the first Australian marine animal to be listed as critically endangered
Scientists have begun a captive breeding program for the spotted handfish, 11 years after it became the first Australian marine animal to be listed as critically endangered.
Endemic to Tasmania, the spotted handfish or Brachionichthys hirsutus looks like a tadpole in the late stages of development, with a fin atop its head to lure unsuspecting prey and the sour expression of a British bulldog.

Devastated land, scarred by peat digging, has been transformed into suitable habitats for birds unfamiliar to the UK
The news that night herons had bred in Britain for the first time barely registered on the ornithological Richter scale. Perhaps this was because it happened on the Somerset Levels, the UK’s new hotspot for long-legged wading birds.
Over the past couple of decades, first little egret, then little bittern, great white and cattle egrets, and now night herons, have flown across the Channel. Many ended up on the Somerset Levels, liked what they saw, and settled down here. Meanwhile, bitterns came over from East Anglia, while cranes were given a helping hand from us, via a reintroduction scheme. Now that we can see five or six of these exotic newcomers in a day, we have become rather blase about them.

As Hurricane Irma battered the Caribbean, trees aerodynamically adapted to strong winds stood firm
When Storm Aileen ripped across the UK last week the worst of the winds brought down trees, snapped off branches and shredded leaves, made worse because the trees were in full leaf and caught the wind like a sail. Compare that with the palm trees that stood up to Hurricane Irma’s immensely stronger winds, which would have torn British trees to shreds. The palm trees simply bent over at crazy angles and then bounced back again.

A world-leading system in Sydney’s Central Park precinct helps residents reuse up to 97% of their water. But a pricing change threatens future schemes
In the basement of a Sydney housing development is the world’s largest water recycling plant in a residential building.
Normal apartments put more than 90% of the water they consume back into the sewer. But thanks to the recycling plant, units in Central Park, built on the site of the old Carlton brewery close to the CBD, return just 3%.

I wholeheartedly agree with much of your editorial (14 September), as the economics of new nuclear is weaker than ever at a time when renewables are coming in cheaper year on year. You point out the crisis in the funding of renewables and we could not agree more. The UK desperately needs to reboot financial support for decentralised energy in order to maximise long-term benefits for all. Councils, in particular, are calling for the restoration of feed-in tariffs and other support that has been instrumental in the creation of innovative, local, low-carbon energy schemes, Passivhaus-accredited buildings, and energy efficiency programmes for dealing with the scourge of fuel poverty.
While the dramatic cost reductions in offshore wind are to be welcomed, it has to be joined with renewed support for decentralised energy projects, approval for tidal energy schemes and the resumption of support for solar and onshore wind. The government must see that the energy landscape has changed dramatically. An energy review and reboot is urgently required.

Agriculture holds the key to unlocking Africa’s vast economic potential | Letters
Only the final paragraph in your article on cocoa farming causing deforestation in Ivory Coast (Forests pay price for world’s taste for cocoa, 14 September) mentioned the most fundamental thing – the farmer’s livelihood, or lack of it. The low value of his (or more likely her) crop is undoubtedly the cause of this problem. But cocoa farming could also provide the solution.
Recently, I was in Ivory Coast for the African Green Revolution Forum (AGRF) in Abidjan. It united many different parties – governments, the UN’s Food and Agriculture Organisation (FAO), private sector agribusiness like Syngenta, Bayer and OCP, Rabobank and the World Bank, the Rockefeller Foundation, and Bill and Melinda Gates Foundation. They are united in one firm belief: that agriculture holds the key to unlocking Africa’s economic potential – 41 million smallholders on a fertile continent that grows every crop imaginable.

Mail on Sunday criticised by Ipso for article claiming global warming data had been exaggerated to win Paris climate change agreement
Claims in the Mail on Sunday that global warming data had been exaggerated in order to secure the Paris climate change agreement have been criticised by the UK’s press regulator.
The Independent Press Standards Organisation censured the newspaper for publishing a story in early February that was flawed in key aspects. The news story suggested that data from the US National Oceanic and Atmospheric Administration (NOAA), one of the world’s gold-standard sources of weather and climate research, had been treated in such a way as to suggest greater warming than had really occurred.

Nancy Hatch Dupree, who has died aged 89, was an American archivist, writer and champion of Afghanistan’s culture and its people, who defied communists, fundamentalists, warlords and foreign invaders over nearly five decades in Kabul.
Her most important legacy is an archive documenting some of the darkest periods of Afghan history: turbulent years of civil war and Taliban rule that many would happily have let slide into obscurity. The documents are housed in the Afghanistan Centre at Kabul University, established in 2006 and one of the city’s most impressive post-Taliban buildings, inspired by traditional architecture and a reflection of Nancy and her husband Louis Dupree’s love of Afghan culture.
