The use of monies from the charge for plastic carrier bags to fund dementia research is most welcome (Report, 6 October). However, I hope that the research will include not only Alzheimer’s but the second most common form of dementia, dementia with Lewy bodies. This most devastating dementia, which also links to the symptoms of Parkinson’s disease, is rarely referred to and mostly unknown to the public despite there being 130,000 sufferers in Britain. As a first step to raise awareness, maybe Alzheimer’s Society should change its name to Dementia Society UK.

OECD report showing extent of existing pledges towards $100bn target to help poorer countries tackle climate change, gives further hope for success in ParisRich countries and businesses have provided close to two-thirds of the financial assistance pledged to poorer nations as part of the global climate change negotiations, ahead of the Paris conference this December.

Rachel Kyte says governments at the 2009 summit agreed funding for developing countries by ‘picking a $100bn figure out of the air’The Paris conference on climate change should not set a target for future financial assistance to developing countries, according to the World Bank’s top official on climate change.

Every day, millions of internet users ask Google life’s most difficult questions, big and small. Our writers answer some of the commonest queriesLoud voices dismiss organic food as nothing more than a trendy 21st-century lifestyle choice for the neurotic rich, but this is a phony argument. There’s nothing new or modish about organics – until the 1950s, all the food we ate was organically produced. It’s organic food that should be considered “normal”, not the upstart, factory-farmed, agrochemical stuff that’s only been on our shelves for a few decades. And the reasons for eating organic food, and supporting organic farmers and growers, are becoming more compelling, not less.Related: Organic food: it's not just for yuppies anymore | Tracie McMillan Continue reading...

Campaigners say a charitable scheme to install solar panels in schools in England and Wales will be ‘unsustainable’ if cuts to the feed-in tariff go aheadA charitable project that has installed more than 1,000 solar panels on schools in England and Wales will close next summer if government proposals to cut support for renewable energy go ahead.Campaigners said on Wednesday that the “solar schools” project run by environmental charity 10:10 would become unsustainable under government proposals to dramatically cut the feed-in tariff for householders and communities who install solar panels on rooftops.

Wenlock Edge, Shropshire: Once thought of as a threat to the UK’s native oaks, these horny growths have joined the rich community that inhabits the treesOn one of the finest autumn days for years, sharply lit under a Wedgwood sky, the oak bears strange fruit. Little green and brown apples covered in horny, foliate protuberances grow where acorns should be. They formed last month when a tiny gall wasp, Andricus quercuscalicis, inoculated embryonic acorn buds with her eggs. The oak responded in an entirely specific way to this wasp by producing growths known as knopper galls, from a German name for a type of helmet.They weren’t seen in Britain until the 1960s, but there was a spike in the knopper population in 1979 and people were worried that the iconic British oaks were in danger of not producing viable acorns. Although the wasps have spread as far north as Scotland, this has not been the case, and knopper galls have joined the rich community of life that inhabits the oaks. The galls are communities themselves, too, containing microhabitants such as inquilines (cynipid wasps lay eggs in the gall and their larvae feed on the oak tissue) and parasitoids (chalcid and ichneumon wasps inject their eggs into the gall wasp larvae to feed on them).

In a bid to protect their land, the indigenous people are challenging the Morales government over decrees opening up protected areas for oil and gas explorationThe history of Bolivia’s Guaraní, an indigenous people living in the country’s southern lowlands, is one of struggle in defence of their territory. In 1892, an uprising against local landowners ended with the massacre of more than 2,000 Guaraní. A century later, Guaraní activists confronted oil companies seeking to exploit the riches buried under their homeland of the Bolivian Chaco.Now they are preparing to fight on a new front. On 24 September, three Guaraní leaders travelled from the dry heat of lowland Chaco to the chill mountain air of La Paz to deliver a legal petition to the country’s constitutional court, challenging a series of energy decrees passed by the government of President Evo Morales.

In addition to mitigating the emissions that cause climate change, conserving tropical forests contributes to development in myriad waysForests are undervalued assets in meeting the twin global challenges of our time: achieving prosperity and safeguarding climate stability. It’s time we gave them the attention – and finance – that they deserve.Last week, dozens of countries announced a late-breaking wave of commitments to reduce greenhouse gas emissions ahead of the climate change summit in Paris this November. While such pledges are welcome, they are not yet sufficient to avert catastrophic global warming. Tropical forests provide an opportunity to close the gap. Continue reading...

We must prepare for climate change now if we want to achieve the global goal of making cities and human settlements inclusive, safe, resilient and sustainableMaking cities and human settlements inclusive, safe, resilient and sustainable is now a global goal following the adoption of the post-2015 development agenda in New York in September. Achieving this target – sustainable development goal 11 – is vital because, for the first time in our history, more people live in cities than live in the countryside. And it is urgent because a third of the urban population lives in slums, mostly located on hazardous land, with poor access to basic services, and few opportunities to earn a decent living.Another huge challenge is that urban areas mostly develop along coasts and rivers, making many city dwellers vulnerable to the effects of climate change. This has led to a growing discussion on how to make cities resilient to flooding, rising sea levels, heatwaves and other harmful results of our changing climate. However these discussions are not yet taking place on a practical level, and there is no blueprint for immediate action. Continue reading...
