What was it like before the Clean Air Act of 1956? Share your memories

The Guardian - Thu, 2016-06-09 20:38

Sixty years on since the introduction of measures to reduce air pollution we’d like to hear your smog recollections

In 1952 the great smog of London saw a week-long pea-souper take over the capital which contributed to the deaths of at least 4,000 people. In response to the disaster, the government passed the Clean Air Act of 1856 aimed at reducing air pollutants.

Recently, the new mayor of London Sadiq Khan unveiled plans to substantially increase the size of London’s clean air charging zone to tackle the capital’s illegal air pollution levels.

Nasa to map coral reefs from the air to show impact of climate change

The Guardian - Thu, 2016-06-09 19:31

Scientists hope large-scale maps will offer new insight into effects of warming and pollution as previous studies have almost always been done up close in the water

Coral reefs have almost always been studied up close, by scientists in the water looking at small portions of larger reefs to gather data and knowledge about the larger ecosystems. But Nasa’s Jet Propulsion Laboratory is taking a step back and getting a wider view, from about 23,000 ft above.

Nasa and top scientists from around the world are launching a three-year campaign on Thursday to gather new data on coral reefs like never before.

Alaska on track for hottest year since records began

The Guardian - Thu, 2016-06-09 18:59

Warmest spring on record helps push states’s year-to-date temperature more than 5.5C above average, reports Climate Central

Alaska just can’t seem to shake the fever it has been running. This spring was easily the hottest the state has ever recorded and it contributed to a year-to-date temperature that is more than 10°F (5.5°C) above average, according to data released Wednesday by the National Oceanic and Atmospheric Administration (Noaa).

The Lower 48, meanwhile, had its warmest spring since the record-breaking scorcher of 2012.

Satellite eye on Earth: May 2016 – in pictures

The Guardian - Thu, 2016-06-09 18:00

Rolling sand dunes of Arabia, thinning glaciers of Greenland and wildfires of Fort McMurray in Canada were among the images captured by European Space Agency and Nasa satellites last month

Nasa astronaut Jeff Williams captured this image of the ancient Potidea canal in Greece from the International Space Station. For 2,000 years this canal has connected the Thermaikos and Toronaios Gulfs. Williams posted the photograph on Twitter, saying: ‘Coastal currents and erosion over 2,000 years appear to have displaced the two sides of this isthmus, which may explain the coastline’s misalignment.’

What has the EU ever done for my … beach?

The Guardian - Thu, 2016-06-09 16:00

Huge sections of the UK coastline were too polluted for swimming until EU legal action forced the government to clean up

In the 1980s, the British government tried to claim that the beaches of Brighton, Blackpool, Skegness and many other resorts weren’t used for bathing, to avoid dealing with the sewage, condoms and tampons that polluted them. Of the 27 beaches it agreed were used for swimming, nine were too dirty to reach the minimum bathing standard.

Today, after legal action from the EU and directives on bathing water and urban waste water, 99% of the UK’s 632 designated beaches have been deemed safe for swimming.

Government failing to protect communities at risk of flooding, MPs say

The Guardian - Thu, 2016-06-09 15:01

Environment committee report criticises lack of long-term planning and raises doubts whether target of protecting 300,000 homes by 2021 would be met

The government is failing to protect communities at risk of flooding, according to a highly critical report from MPs, who said they were sceptical that the target of protecting 300,000 more homes would be met.

Ministers react after severe flooding rather than planning ahead for the long term, according to the cross-party environmental audit committee (EAC), which said flood defences are not sufficiently maintained.

The bloody-nosed beetle: a tank on sticks

The Guardian - Thu, 2016-06-09 14:30

Dartmoor, Devon The beetle’s forelimb seemed to give a cheery wave to the world as it scooped at thin air then arced forward

Wider than a thumbnail, almost as thick as a thumb, a black beetle with a shell like polished shoe leather was lumbering along a well-trodden path.

Striking out in slow motion for the grassy edge with a six-legged doggy paddle, this bloody-nosed beetle (Timarcha tenebricosa) gave the impression of a wind-up toy winding down. Watching this great tank on sticks was akin to seeing the open workings of a mill – a collection of mechanical parts moving in sequence to drive the greater whole.

How the Great Barrier Reef got polluted – from farms and fossil fuels to filthy propaganda | Graham Readfearn

The Guardian - Thu, 2016-06-09 08:40

Policies and rhetoric around the Great Barrier Reef have rarely matched reality as the natural wonder suffers under the stress of pollution

In late November 2015, as corals across the northern section of the Great Barrier Reef started to bleach white, the game was finally up.

For years, Australians had been told the country’s jewel in the ocean’s crown was on the mend. Only months earlier the coalition government had won a two-year fight to keep the reef off a United Nations list of World Heritage sites in danger.

Coal was king of the Industrial Revolution, but not always the path to a modern economy

As the world moves to combat climate change, it’s increasingly doubtful that coal will continue to be a viable energy source, because of its high greenhouse gas emissions. But coal played a vital role in the Industrial Revolution and continues to fuel some of the world’s largest economies. This series looks at coal’s past, present and uncertain future, starting today with how it’s formed.

Coal was king of the British Industrial Revolution. As coke, it provided an efficient fuel for reliably turning iron ore into iron.

Cheap iron built the famous bridge across the River Severn at Ironbridge Gorge in 1781. And the machinery that filled the new factories of the industrial age was built from it.

Coal then powered the machinery and lit what English poet William Blake (1757-1827) described as the “dark satanic mills” that revolutionised cotton manufacture. It powered James Watt’s double-acting piston engine, whose reciprocating motion was converted into rotary motion by means of a crankshaft.

The resulting steamships and railway locomotives reduced the time and cost of bringing coal into factories and taking their products to British export markets across the globe.

Somewhat unexpectedly, the new forms of transport also generated exciting adventures for the British population – the mass seaside resort and the day return. Thus were Thomas Cook and the British tourism industry born.

Spoils of coal

Coal literally powered its way through the British economy of the 19th century – the so-called first industrial nation and workshop of the world.

It even fuelled engines that drained water from deeper, less accessible coal mines to keep the supply coming. When steel superseded iron later in the century, coal remained a critical raw material.

Subsequent generations of locomotives and steamships improved transport productivity enormously, and gradually forced owners of stagecoaches, canal boats and sailing ships out of business. Then locomotives, rails, steamships and coal themselves joined the growing range of British exports as other countries sought to mimic the nation’s success.

Ironically, many ageing sailing ships were deployed to carry coal to refuel the growing network of coal bunkering stations around the oceans of the world, a trade that required low cost but no particular urgency.

Fast, reliable ocean liner services contributed to the first era of globalisation in the late 19th century, led by British steamship companies such as Cunard and P&O. They connected Britain across the Atlantic and eastwards, respectively.

Other countries followed suit, especially France, Belgium and Germany, which also had ample supplies of coal. While no one would deny the connection between coal and 19th-century industrialisation, why Britain was the first nation to modernise its economy by exploiting reserves remains highly contested.

Why Britain?

A long-held view is that the antecedents of British success can be traced back centuries during which the nation gradually built the preconditions for modern development. Growth-inducing institutions can take many forms, and include a stable political system and the development of commercial law.

The emphasis in Britain was on rising literacy levels and logical reasoning derived from movements that encouraged analytical thinking about the problems of the real world – the scientific revolution and the Age of Enlightenment.

These “gifts of Athena” (in the words of economic historian Joel Mokyr) facilitated critical and creative thinking about “useful knowledge” necessary to solve growth constraints. In modern parlance, here was the knowledge economy.

This “Eurocentric” view – so-called because it assumes that development in Britain (and Europe) was ahead of the rest of the world – has now been challenged.

In his epochal study, The Great Divergence, US historian Kenneth Pomeranz used China as a point of comparison to reject the long-term antecedents of the “great divergence” between the economic development of Europe and the rest of the world.

Pomeranz argues that Britain and China had arrived at similar stages of development by the 18th century (“a world of surprising resemblances”, as he calls it) and that they reflected different, but equivalent, measures of progress.

The divergence was then born of differing abilities to confront an impending global ecological crisis: growing populations faced food and raw material shortages in a low-technology era.

Fortuitously, Britain had coal, conveniently located, and an empire in the New World with the space to produce primary commodities – timber, sugar, cotton and wheat – which, alongside coal, facilitated industrialisation.

Pomeranz concludes that Britain was a “fortunate freak” because its development was due to a short-term windfall from “coal and empire”, rather than to deeper determinants of long-term change.

Paths to growth

The publication of The Great Divergence led to a broad and thought-provoking debate in economic history for a decade and a half.

What we learnt from it – above all else – was that there have been different forms of economic development across the world. And some of these have been pathways less recognisable to Europeanists accustomed to coal and heavy industry as staples, and Gross Domestic Product (GDP) as the measure, of development.

Other historians have drawn attention to forms of industrialisation, especially in Asia, that have needed more human – and less non-renewable natural – resources.

Now that we are living in an era when coal’s environmental problems have come to the fore, it’s heartening to be reminded that there are other growth paths.

The other relevant insight from the Great Divergence debate is that human agency is vital; there are no immutable lessons of geography or ecology, and no development path is unchanging.

Coal and other resources have always been abundant in many parts of the world. It’s the human ingenuity found in particular societies – however derived – that has created high levels of wellbeing from these natural resources.

Let’s hope we will find a way of maintaining living standards into the future while mitigating the impact of our growth on the environment.

This is the second article in our series on the past, present and future of coal. Look out for other pieces over the coming days.

Residents of Makoko, a vast slum of houses on stilts in a Lagos lagoon, say they will rebuild their pyramid-shaped floating school, after it collapsed in a storm on Tuesday. The school, which became a beacon of hope for the nearly 100,000 Nigerians who live in Makoko, was damaged by heavy downpour, despite being built to specifically withstand the storms and floods that are common in the four-month-long rainy season

European Union is a progressive force in controlling pollution | Letters

The Guardian - Thu, 2016-06-09 04:05

In attributing the rise in air pollutants in London to the EU, Nigel Pollitt is being disingenuous (Letters, 6 June). As chairman of the UK Expert Panel on Air Quality Standards for a decade to 2002, I was regularly asked by journalists as to whether diesel or petrol vehicles were better, and always gave the same answer: it depends whether you wish to increase air pollution or to accelerate global climate change, since diesel was more efficient but also more polluting. Thus it would have been Hobson’s choice, were it not for the unasked alternative, which was to get out of the car or, if that was not always possible, to drive the car with the smallest possible engine and to do so with minimal use of accelerator and brake.

Mr Pollitt should also know that all the evidence-based air quality standards that our panel proposed to the UK government were passed into law and then used by the EU for setting pan-European standards, resulting in a general reduction of pollution across Europe and in the UK. The recent rise in pollution in London is related to the selfish behaviour of those who purchase large diesel vehicles and use them for short journeys when efficient electric and hybrid vehicles are now available.

MPs attack loopholes in cosmetic industry's microbead phase out

The Guardian - Thu, 2016-06-09 02:34

Environment committee criticises voluntary action to end the tiny plastic particles that pollute seas, and slam the lack of labelling on microbead products

Voluntary action by the cosmetics industry to phase out the use of microbeads in Europe came under strong attack from MPs on Wednesday, who criticised loopholes in the pledges and slammed the lack of labelling on products containing the plastic particles.

Tiny plastic beads are widely used in toiletries and cosmetics but thousands of tonnes of them wash into the sea every year, where they harm wildlife and can ultimately be eaten by people. The US has banned microbeads and a petition signed by over 300,000 people asking for a ban in the UK was delivered to David Cameron on Wednesday.
