How can developing countries reach 100% renewable energy generation? Our expert panel had these suggestionsRenewable energy is clearly becoming the cheapest, more scalable and quickest way to provide electricity to the new demand from emerging markets. Currently there is only one key issue, availability of the renewable resource (no sun at night and no-wind days), but new technologies (battery energy storage) are becoming more viable.

The current refugee crisis has its origin in Syria’s complicated civil war – and not a global warming eventThe desperate and the displaced of Syria’s war should not be cast as climate refugees, observers have told the Guardian, as this overstates the role of global warming in setting off the conflict.Many agree that the collapse began in March 2011, when a group of Syrian teenagers sprayed the words “Ash-shab yurid isqat an-nizam” on a wall in the southwest Syrian town of Dara’a.

The United Nations began with 51 member states and an annual budget of $19m. Seventy years on the UN has 193 member nations and spends $40bn a year. Actor Rachel Weisz looks back at its history and asks: how did the UN get so big? And – as the UN marks its 70th birthday – has it stayed true to its founding principles of spreading human rights, social progress and upholding international justice?

Protest group Land Water Future has released a satirical campaign video poking fun at the proposed Shenhua coalmine in NSW. The $1.2 bn proposed mine on the NSW Liverpool Plains is facing a legal challenge over claims the NSW government did not properly consider the impact the mine would have on the local population of koalas, possibly leading to extinction of the group. Chinese state-owned company Shenhua would have to start the approvals process again if it loses the challenge at the NSW land and environment court Continue reading...

Church Norton, West Sussex As the sun comes out, a slim grey greenshank wakes from its slumber and starts to preenThe South Downs are hidden behind low cloud as wind drives the rain across the harbour. Raindrops fall on the brambles all around me and run down the ripening blackberries and blue-grey juniper berries. I put my hood up, cover the telescope and sit on a bench overlooking the harbour, sheltering among the bushes, to wait for the tide to fall.It is hard to imagine now, but the harbour at Pagham once bustled with boats – from Roman times to the 14th century – until storms engulfed the area in 1341. The inlets began silting up and the channels became too narrow and shallow. Continue reading...

Crocodile researcher warns the reptiles face a ‘bleak future’, but Australia’s saltwater and freshwater species have a brighter outlook due to hunting banAs many as half of the world’s 27 species of crocodilian face being wiped out due to human activity, although the most feared variety, the saltwater crocodile, faces a brighter future, according to a new book by a veteran crocodile researcher.Land use changes, pollution, culling and feral animal invasions mean that many crocodile species face a “bleak future”, warned Professor Gordon Grigg of the University of Queensland.

Nations must make a greater effort to reach agreement or else millions face the risk of becoming climate refugees, says French presidentThe president of France, Francois Hollande, has warned that the global climate change talks scheduled for Paris this December will fail unless nations make a much greater effort to reach agreement – and that the result could be millions of new refugees fleeing climate disaster.

Up to 30 trucks are plying on a 32-mile purpose built road illegally carved out in the jungle in Ucayali region, smuggling out tree trunks on an industrial scaleOnly from the air is it possible to make out the scale of three illegal logging roads which have been carved into Peru’s eastern Amazon, while local authorities in the jungle Ucayali region seemingly turn a blind eye.

A new study challenges the traditional assumption that experts are best placed to evaluate how well people could cope with and adapt to an emergencyThe concept of “resilience” is taking development and humanitarian sectors by storm. Huge amounts of finance are being channelled into “resilience-building” activities, aimed at supporting people and communities to deal more effectively with climate extremes, financial shocks and the many other risks that threaten lives and livelihoods.Given the pressure on NGOs, governments and donors to demonstrate value for money and support the right people and activities, the race is on to find the best ways of measuring resilience.

They are touted as a free source of clean, unlimited energy to heat your water but the first independent test suggests they are not as efficient as thoughtThermodynamic panels have been touted as “a free source of natural, clean and inexhaustible energy providing 100% of your hot water needs, 365 days of the year”. For around £5,000 to buy and install, they sound too good to be true – and the first independent tests suggest they are.

But global decline continues and woodland the size of South Africa has been lost since 1990, reports UN’s Food and Agriculture OrganisationThe rate at which the world is losing its forests has been halved, but an area of woodland the size of South Africa has still been lost since 1990, a UN report said on Monday.Improvement has been seen around the globe, even in the key tropical rainforests of South America and Africa, according to a surprisingly upbeat Forest Resources Assessment (FRA), which is released every five years.

Global warming does not cause the conflicts that have caused mass movement of people, but it would be wrong to say it does not contributeAs I looked in on my own children sleeping safely last Thursday night before I went to bed, I did so with added poignancy as I reflected that this was something Abdullah Kurdi was not able to do. I’m sure millions of parents of young children right across Europe have felt similar emotions these last few days.We’re all human, and so it’s perhaps not surprising that it takes a single photograph and an individual’s story to shake a society, all too belatedly, into glimpsing at one horrific aspect of Europe’s refugee crisis and demanding action.

Carrifran valley, Scottish Borders There is a real sense here of what the glens, cwms and valleys of the British Isles would be like if they were let off the leashThe ground steepens into a glacier-gouged corrie, and walking into it feels like crossing an invisible threshold. A slope falls away below us, steep and unnervingly slick with rain, above which hundreds of small white butterflies flicker in a low cloud, charging the air with the same soft suspense that comes with falling snow. After this muted summer, it comes as a surprise to find so many butterflies here, gathering secretly in the upper reaches of the Carrifran valley.We wade gingerly downwards into a corrie coated with life; a montane of blaeberry and bog myrtle, harebell and hogweed, tormentil, asphodel, wild grasses and huge marshmallows of moss, all growing in amounts that feel strangely luxuriant for the altitude.

Originally published in the Manchester Guardian on 9 September 1915A curiosity of this season is the number of flies that come into the house. Flies do not seem to be conspicuously more numerous elsewhere, yet the window panes in the room where I am now writing are black with them, and there is a constant peppering against the glass from outside as though half-a-dozen pea-shooters were making a concerted attack upon me. I fancy that as the mornings and evenings grow chillier flies are more and more attracted to the warm and sunny surface of the house-walls and beat the windows in intervals between sun baths.The whole countryside seems to take the sunshine like a bath these delicious September afternoons, and here in Oxfordshire we associate the grateful autumnal heat with the sleepy sound of the slow rolling of loaded waggons along all the roads that lead into the village. Our farmhouses are mostly in the village street, with their rick-yards beside them, and the corn is brought in from the outlying fields and stacked at the homestead. This system no doubt has its conveniences, though it must delay operations immensely at a critical season. It has its merit to the outside observer in this long low rumbling which now fills all our ears - as though content and plenty had found a voice. Continue reading...

Annual naming event fetes a conservation success story and burnishes the reputation of the country’s president Paul KagameIt was a scene reminiscent of Planet of the Apes or 2001: A Space Odyssey. Two dozen performers wearing hairy gorilla suits, complete with masks and rubber boots, scampered along a bamboo bridge, beat their chests and cavorted in a field at the foot of a volcano.The occasion was Rwanda’s annual naming ceremony for mountain gorillas. Since the 24 babies born in nearby wild habitat over the past year had failed to RSVP, a group of parents and children in costumes gamely played their parts instead, grunting and rolling in the grass to the delight of thousands of villagers, diplomats and president Paul Kagame.

It’s one set of principles for fracking and another for renewablesHuw Rowlands (Letters) goes too far when he says: “Anyone who has researched the fracking industry is against it.”His assertion ignores a large body of research into fracking that has been and continues to be undertaken by the geological community, including the Earth sciences departments of several of our finest universities. If Mr Rowlands were to discuss the matter with a cross-section of the geophysicists, hydrologists and environmental scientists who work on this subject he would find a wide range of opinions.

As Community Energy Fortnight beings, investors can check out the renewable schemes offering returns of up to 13%Richard Body is an energy pioneer. The IT consultant is a director of the Torrs Hydro scheme in New Mills, Derbyshire, which was one of the first community-owned hydroelectric schemes to launch in the UK.Sited on the river Goyt, where it tumbles out of the Peak District, the scheme produces enough electricity to power 60 homes. “There was power in the river that nobody was tapping into – in effect it was free money,” Body explains, who was awarded an MBE in 2013 for services to the hydroelectric industry. “Our aim was that by generating electricity, we could also generate a revenue stream for the local community.” Continue reading...

Almost a decade after banning the veterinary drug diclofenac, the Indian government has banned large vials of the drug meant for human useThe government of India’s Ministry of Health and Family Welfare finally issued a directive banning multi-dose vials of the non-steroidal pain-killer diclofenac in the last week of August.

Pumsaint, Carmarthenshire Thunderous and dark, it’s one of those places where the forces of landscape are gathered into fearsome expressionThe lane from Ffarmers descends to the afon Cothi and turns sharply north-east towards Rhandirmwyn. Every verge, every marshy field corner hereabouts billows with creamy blossom of meadowsweet (Filipendula ulmaria). The air is heavy with its honeyed astringency – the defining smell of summer and Wales, lingering into autumn, carrying a powerful synaesthetic charge.Salicylic acid was first identified from meadowsweet root, and synthesised as aspirin in 1897. Far back beyond that date, the plant’s alternative name – meadwort – suggests its old usage. Traces of it have been found at beaker burials, in bronze age tombs. Continue reading...

Taking a cue from pope’s call to action, bishops ask wary legislators to say yes to proposed legislation that would reduce emissions and residents’ energy useCiting Pope Francis’s recent encyclical on the environment, leaders of the Catholic church in California spoke out this week to encourage wavering lawmakers to vote in favor of proposed sweeping climate change legislation that is struggling for passage in the final days of this session of the California legislature.Speaking about SB 350, a bill that would reduce petroleum emissions by 50% in coming years along with restrictions on other kinds of energy use, Bishop Jaime Soto of the Sacramento diocese urged tentative lawmakers “to really think about the future of California and the future of Californians and what is the legacy we want to leave them.

The Conservative government’s fortress-style border policies at home and its wars abroad are a lethal contribution to a global refugee crisisUndeserving people exploiting the generosity of a benevolent government. Cheating an application process. Taking advantage of welfare. Stealing our jobs. That is the image of “bogus refugees” that Canada’s Conservative government has spent years carefully cultivating. But a single photo of a drowned child has shattered all the stories meant to harden Canadians. 3-year old Alan Kurdi’s fate off Turkey’s shore has seared the reality of a refugee crisis into our consciousness and left Canadians stunned about our complicity in the death of a child.Those now putting Canada’s refugee policies under scrutiny will realize that this much else is clear: the Harper government has more than one refugee’s death on its hands. It is not simply that Alan Kurdi’s family’s attempt to reach Canada was dismissed by the government. Nor that Canada’s Immigration Minister ignored a hand-delivered plea. Under the Harper government’s overhaul of the immigration and refugee system, those fleeing war, poverty or persecution arrive not to a haven but a hazard. Never has this country been more unkind and unwelcoming. Continue reading...

Solar trade body chief claims energy secretary Amber Rudd told him the impact on jobs was not part of the consultationThe potential loss of thousands of jobs will not be a factor when the government decides whether to implement its proposed heavy cuts to solar power subsidies, according to the chairman of a solar trade body who met energy secretary Amber Rudd on Wednesday.By contrast, recent government announcements on North Sea gas field development and the fast-tracking of shale gas exploration have highlighted the potential jobs created.
