Bare trees show their clean anatomy: Country diary 100 years ago

Mon, 2016-12-12 08:30

Originally published in the Manchester Guardian on 14 December 1916

Passing through the Severn Tunnel one got a strange contrast in weather. On the Welsh side mist, clinging, cold, dreary; on the English side hoar frost over the grass, a blue sky and hot sun overhead. The trees are bare now and showing their clean anatomy. Never are they more lovely than when one can see every finest twig outlined with characteristic gesture against the sky. Elms especially show to advantage when bare; where they have to be lopped for safety it is indeed a sore sight, for their habit of ending in a fine spreading plume is so individual and so beautiful. Along the banks of a canal the rows of pollard willows make quaint reflections in the still water. Farther on, by the river, the beech woods are grey, with scarcely a shade of brown from the tightly packed scrolls of buds. But the chestnut tips are thick and sticky, and it will be worthwhile cutting a few branches to put into water. Sprays of birch also may be treated in the same way, and it is a great joy to watch them unfold.

Why logs are twice as dirty as diesel

Mon, 2016-12-12 07:30

We think of wood burning as natural, but experiments show that wood smoke contains shocking levels of harmful particles

Walk round many suburbs on a winter’s night and your nose will tell you that wood burning is being used for home heating. A recent UK government survey found that 7.5% of UK homes now burn wood. The vast majority use it for supplementary heating or decoration. Wood burning is most popular in the south-east where it is used by around 16% of households and it is least popular in northern England and Scotland where it is used by less than 5%.

We think of wood burning as being natural and therefore less harmful to the environment when compared with fossil fuels. However, particle pollution from UK wood burning is now estimated to be more than double diesel exhaust.

Reduce EU quotas to stop overfishing | Letters

Mon, 2016-12-12 05:32

This week EU fisheries ministers meet to decide the north-east Atlantic fishing quotas for 2017 at their annual December conference. Let’s hope our minister, George Eustice, does not repeat his performance of last year, when – in the face of a desperate need to end overfishing – he acquired for the UK a 2016 quota that exceeded scientific advice by more than any other EU country and proclaimed this as a good deal. Overfishing is “a good deal” only for the short-term interests of the smallest but wealthiest sector of the fishing industry, whose mega-trawlers hoover up the stocks, destroy their habitats and exacerbate their chronic over-exploitation. It is to be hoped that Eustice will also conform to another requirement of the common fisheries policy – the provision of a greater share of the quota to the small, under 10-metre, boats that constitute the largest part of the fleet, fish more sustainably, employ more fishermen, provide real benefits for their communities and enhance their prospects of both survival and a renewed prosperity. While representing about 80% of the Welsh and English fleet, they have just 6% of the quota.

Windfarm in Barnaby Joyce's NSW electorate gets $120m CEFC loan

Mon, 2016-12-12 03:00

Clean Energy Finance Corporation loan comes three months after minister slammed SA’s over-reliance on wind power

The Clean Energy Finance Corporation has made a multi-million dollar loan for a new windfarm in Barnaby Joyce’s electorate.

It comes three months after Joyce slammed the South Australian government’s over-reliance on wind power, and linked SA’s damaging September blackout on the state’s lack of coal-fired baseload power.

The ethical guide to the Anthropocene

Sun, 2016-12-11 16:00

We humans have polluted our world into a new geological epoch

If you’re feeling unsettled by the Brexit/Trump future, consider this: since the 1950s humans have ramped up the pressure on the planet to such an extent that we have very likely propelled ourselves into a new geological epoch – the Anthropocene. Now that’s what geologists call change. The thing that freaks me out is that it’s rarely mentioned.

To unwrap that: for the past 10,000 years or so, we have hung out comfortably in what we call the Holocene epoch. During this period we have been able to rely on the Earth’s systems to dampen the effects of “forcings”. These are different factors that affect the Earth’s climate, such as volcanic eruptions and solar variations.

Australia's changing landscape through Google timelapse – video

Sun, 2016-12-11 15:06

Google’s timelapse project allows users to see how anywhere in the world has changed in the past 32 years using Landsat satellite images. These images of Australia show the extent of development around its largest cities, as well as the changes brought by projects such as the Cubbie Station cotton plantation in Queensland, the Fimiston goldmine in Western Australia and mining development in the New South Wales Hunter Valley.

Another day, another dead wildlife ranger. We must do more to help them

Sat, 2016-12-10 18:18

Every year more than 100 wildlife rangers are murdered in the line of duty. Why do they get so little support? And where is the outrage?

Cameroonian ranger killed by wildlife poachers

As we sat by the campfire, Gervais, a ranger from the forests of Malawi, slowly pulled back his hair to expose a 20cm scar left by a machete attack that nearly killed him. Poachers, he told me.

I was at an international rangers’ conference, held 13 years ago in a national park on the southern tip of mainland Australia. Another ranger, Jobogo Mirindi from the Democratic Republic of the Congo (DRC), showed me a photo taken five years before. Arranged football team-style were 30 or so of his smiling colleagues. Six rangers’ heads were circled in red; those were the only ones still alive.

Cameroonian ranger killed by wildlife poachers

Sat, 2016-12-10 18:18

Two to three rangers are being shot a week as poachers step up their predations on the world’s wildlife

Another day, another dead wildlife ranger. We must do more to help them

A Cameroonian ranger was ambushed and killed by ivory poachers on Wednesday while patrolling to protect elephants and gorillas. During the last morning of a 10-day patrol in Lobéké National Park, Bruce Danny Ngongo was shot three times, once in the thigh and twice in the hip.

“[Ngongo fell after] an ambush by a gang of poachers heavily armed with Kalachnikov [sic] who immediately opened fire on the surveillance staff,” said Lobéké National Park director Achille Mengamenya Goue, in a letter sent on the evening of the incident to Cameroon’s forestry and wildlife minister, Philip Ngole Ngwese.

An elemental challenge for climbers and storm-watchers

Sat, 2016-12-10 15:30

Bosherston, Pembrokeshire To stand on the cliff as green combers thud into the walls beneath, roar into the cave and recoil in white chaos is to become aware of even rock’s fragility

The bird ledges on Mowing Word, a cock’s spur of a limestone point on the south Pembrokeshire coast, are empty now. The guillemots and razorbills that jostle, cackle and croon here through the spring months, their single eggs perilously free from nests’ constraints, are far out to sea, searching for food.

The cliff on wild days is storm-watchers’ domain. To stand on top as green combers thud into the walls beneath, roar into the cave and recoil in white chaos is to become aware of even rock’s fragility. Sometimes the whole narrow headland shakes beneath your feet, and white spume that looks so light lashes the skin.

Anti-fracking activist spared jail after refusing to pay court £55,000

Sat, 2016-12-10 04:19

Tina Louise Rothery – part of a protest group known as the Nanas – staged a three-week occupation of a field near Blackpool

An anti-fracking campaigner has been spared jail after she refused to pay more than £55,000 of legal fees to the oil and gas firm Cuadrilla.

Tina Louise Rothery, 54, had been ordered to pay £55,342 of fees to the British company and a group of landowners, or face a 14-day prison sentence, after she sought to stop an injunction that would prevent protesters gathering on a stretch of land being considered for shale gas exploration.

Indigenous land rights key to stopping deforestation in Central America

Sat, 2016-12-10 01:37

Without their traditional land managers, conservation reserves in Central America are left vulnerable to corporate interests, report finds. Climate Home reports

Conservation reserves in Central America have shut indigenous peoples off from their traditional lands and driven deforestation, community leaders have told Climate Home.

Since revolution in the region started to wind down in the 1980s, there has been an internationally celebrated trend to create large conservation areas. Hundreds of thousands of square kilometres of forest have been placed within borders designed to protect them.

ECB's quantitative easing programme investing billions in fossil fuels

Fri, 2016-12-09 23:36

EU emissions pledge could be undermined by bank’s investments in oil, gas and auto industries, new analysis shows

The European Central Bank’s (ECB) quantitative easing programme is systematically investing billions of euros in the oil, gas and auto industries, according to a new analysis

The ECB has already purchased €46bn (£39bn) of corporate bonds since last June in a bid to boost flagging eurozone growth rates, a figure that some analysts expect to rise to €125bn by next September. On Thursday the bank said it would extend the scheme until 2018.

Alan Finkel warns investment has stalled over climate policy uncertainty

Fri, 2016-12-09 17:52

Australia’s chief scientist vows to ‘thoroughly analyse all options’ for energy market despite row over emissions trading

Australia’s chief scientist, Alan Finkel, has tried to stay out of the fresh political row over emissions trading but says his review of the energy market will continue to analyse all the options to ensure future security of power supply and compliance with climate obligations.

Finkel’s comments follow a briefing he gave on Friday to the prime minister and state and territory leaders about his preliminary report about the state of Australia’s energy market. He warned that investment had stalled because of national policy uncertainty, and concluded current federal climate policy settings would not allow Australia to meet its emissions reduction targets under the Paris agreement.

Great Barrier Reef not likely to survive if warming trend continues, says report

Fri, 2016-12-09 16:46

Report projects by 2050 more than 98% of coral reefs will be afflicted by ‘bleaching-level thermal stress’ each year

The Great Barrier Reef will not survive coral bleaching if current sea temperature trends continue, according to a new report charting increases over the past three decades which blames manmade climate change for the problem.

The study found thermal stress to coral reef areas was three times more likely when its investigation finished in 2012 compared with when it began in 1985, forecasting “more frequent and more severe” bleaching through the middle of this century.

Black swan becomes black sheep in the mob

Fri, 2016-12-09 15:30

Langstone Harbour, Hampshire The black swan shrank back as the mute swans stomped up the mud bank towards us and jostled for a handout

The tide was out and as I approached the mill outflow I could see a black swan hunkered down on the exposed shingle. Native to Australia, black swans were introduced to Britain in 1791 as ornamental birds in captive wildfowl collections. Due to inevitable escapees and deliberate releases, sightings in the wild are widespread. Now, the number of breeding sites are increasing at such a rate that Cygnus atratus may be on the brink of establishing a self-sustaining population.

This was the fifth black swan to visit the creek in a fortnight and, as they often pair up during the winter months, it is likely that these birds were roaming in search of a mate. This swan didn’t sport the jet black velvet lustre of mature adult plumage – its sooty feathers had a charcoal grey cast and were fringed with taupe, which gave it an almost scaly appearance.
