In July 2013, a large, strangely shaped beetle emerged from the fabric of a wooden chair that had just been bought in the UK. The inch-long creature had developed inside the chair’s wooden frame before it ate its way to the surface and burst through the seat’s plastic covering – much to the alarm of its purchaser. Crucially, the furniture had been made in, and imported from, China.

Analysis by Fera Science, formerly the Food and Environment Research Agency, showed the beetle was a Japanese pine sawyer. Worse, the beetle was found to be infested with a second serious pest: the pinewood nematode worm. In combination, the beetle (Monochamus alternatus) and worm (Bursaphelenchus xylophilus) have been linked to widespread damage to pine forests in China and Japan. Now it is spreading through parts of Europe.

How highly should we rate the energy ratings?

It’s not very rock’n’roll, but I’ve always loved an energy rating. A third of the UK’s greenhouse gas emissions come from Energy Using Products (EUPs) in offices and industry and also, significantly, in our own homes, too. The ones we control can really help to reduce that percentage, so choosing the best energy-rated model makes sense.

EU energy labels give us an easy way to power down. Regulated by European law, they can help us see how efficient a product is before we buy it, and also mandate vampirical products that suck power out of the grid when you think they’re asleep (since 2010 products cannot have standby power greater than 1W). Don’t ask me what happens after Brexit. I worry about that, too.

Ministers reveal 169 local authorities breached annual legal limits on nitrogen oxide, linked to lung disease, last year

Four in 10 of Britain’s local authorities breached legal air quality limits last year, largely due to heavy road traffic, government records reveal.

Ministers have admitted that 169 local authorities were found to have gone over annual limits on nitrogen dioxide. It is an invisible gas produced predominantly by road traffic, and is linked to lung disease and cardiovascular problems such as heart attacks and strokes.

Borrowdale, Lake District Borrowdale is thriving following an era of being successfully farmed by generations of Westmorland hill farmers

Several faces, mottled black and white, glance up as I alight from the car. On seeing no dog, these Rough Fells – burly ewes with horns – return to grazing the open fell, unalarmed.

Following the A685 Kendal road south from Tebay in the Lune Gorge, I had turned off through woodland of rowan, alder, birch and holly, and parked along a byway running for nine miles west towards Shap summit through the “other” Borrowdale. This is Howgills country, lonely and mysterious and devoid of the crags and lakes that bring the tourists to the Borrowdale near Keswick. Yet in a reshuffle of the boundaries, it too has recently become part of the Lake District national park.

The suggestion that the previous government failed to address questions surrounding air quality (Report, 20 October) does not reflect the progress that has been made on the issue since December 2015. Since then, the government’s air quality plan, updated modelling undertaken by Heathrow and an independent study by Cambridge University have all shown that baseline air-quality levels around the airport will have significantly improved by the time a new runway is built, as the nation’s vehicle fleet gradually becomes cleaner.

The Airports Commission’s analysis concluded that a third runway at Heathrow can be delivered in accordance with EU air-quality limit law, and would have less impact on health receptors (where people live and work) than a runway at Gatwick would have on the community in that area. A new runway at the UK’s hub airport represents an opportunity to deliver significant improvements to air quality around Heathrow: the redesign of local roads, support for sustainable transport and the opportunity to introduce an airport emissions charge all have the potential to bring improvements in air quality.

Experts say fin whales are normally found on south or west coasts of UK, not on east coast

Mystery surrounds how a rare 12-metre (40ft) fin whale came to be washed up on a beach in Norfolk.

The enormous creature was already dead when it was washed up on Holkham beach, on the north Norfolk coast, on Thursday afternoon.

During the spring harvest season, a group of traditional Malaysian honey hunters travel to the rainforest near the Thai border to collect honeycombs from giant bees – and risk their lives climbing 200ft trees

Solar expected to almost triple in less than three years by 2017 as coal continues to fall, solidifying gas as country’s chief electricity source, reports Climate Central

Solar power capacity in the US will have nearly tripled in size in less than three years by 2017 amid an energy shakeup that has seen natural gas solidify its position as the country’s chief source of electricity and coal power continue to fade, according to monthly data published by the US Department of Energy.

Cutting carbon dioxide emissions from electric power plants is a major part of the US strategy for tackling climate change as the country seeks to meet its obligations under the Paris climate agreement and keep global warming from exceeding more than 2C (3.6°F).

Number of nesting Manx shearwaters almost triples in three years after a project, backed by Prince Charles, sucessfully kills off the rats that eat the birds’ chicks and eggs

A scheme to kill rats on two of the Isles of Scilly, backed by Prince Charles, has led to a resurgence in rare sea birds.

The number of Manx shearwaters has risen to 73 nesting pairs this year, the highest in living memory and almost triple the number of nesting birds just three years ago. The birds appear to be breeding successfully, with 30 chicks spotted on the popular holiday islands. Another species of rare ground-nesting birds, storm petrels, have also returned to the Scillies.

We will soon see a three-peat of record hot annual global temperatures

We know the world is warming – no factor can explain it aside from human emissions of greenhouse gases. Despite this, people who deny the basic facts of climate change have tried to argue that the Earth is either not warming or is only slowly heating. Well that just isn’t true anymore. The last three years are the nail in the coffin of the deniers of climate change. We have enough data this year to call 2016 as the hottest year ever record – and we have three more months left to go.

So, just how hot is 2016? Well my early predictions are shown in the graph below. I have taken temperature data from NASA and superimposed my predictions for 2016 – it isn’t even close. And by the way, it doesn’t matter whose data you use (NASA, NOAA, JMA, Hadley Centre) the results are the same. 2016 is going to blow 2015 out of the water.

Imagine Project sets out to cut waste in the industry by renting rather than selling bikes, which can then be returned and refurbished when the child outgrows them

The idea had been nagging at her for years, but Isla Rowntree went to the ends of the earth before she was finally ready to go ahead with something she hopes will revolutionise the way the bicycle industry is run.

This is the Imagine Project, currently being developed by Rowntree’s eponymous firm making children’s bicycles, Islabikes. It offers a simple but hugely innovative solution to reducing waste – bikes will be rented to customers rather than sold, and returned to the factory for refurbishment when their young rider outgrows them.

Rother valley, Derbyshire The malign dragon’s breath ceased, the air cleared, then a corner of the vast works became a nature reserve

As a boy, rushing south from Chesterfield on the train, I remember how the farmland was interrupted by the Avenue coking works breathing fire and acrid smoke like a malign dragon. Eight hundred people worked there, producing fuel for steel works, along with sulphuric acid and tar, in one of the most contaminated industrial sites in Europe.

Websites pushing climate science denial are growing their audience in an era where populist rhetoric and the rejection of expertise is gaining traction

For years now geologists have been politely but forcefully arguing over the existence or otherwise of a new epoch – one that might have started decades ago.

Some of the world’s most respected geologists and scientists reckon humans have had such a profound impact on the Earth that we’ve now moved out of the Holocene and into the Anthropocene.

Figure of 220-450 annual deaths could be even higher, as killings by poachers or farmers often go undetected in the remote mountains of central Asia

Hundreds of snow leopards are being killed every year across the mountains of central Asia, threatening the already endangered big cat, according to a new report.

There are as few as 4,000 of the solitary and elusive cat remaining and numbers have fallen by a fifth in the last 16 years.

International Whaling Commission meeting in Slovenia follows Japan’s recent slaughter of more than 300 minke whales

Australia has thrown its weight behind a bid to outlaw large-scale commercial and so-called “scientific” whaling at a summit next week.

The International Whaling Commission meeting in Slovenia follows Japan’s recent slaughter of more than 300 minke whales, many of them pregnant, when they resumed so-called scientific whaling after a hiatus because the International Court of Justice ruled the hunts were not scientific and should cease.

Spiders can control their web’s tension and stiffness to help them identify potential partners as well as prey, study shows

Spiders can control the tension and stiffness of their webs to optimise their sensory powers, helping them locate and identify prey as well as partners, according to researchers at Oxford University.

Much in same way that notes travel along a plucked guitar string, spider silk transmits vibrations in different frequencies, sending information back to the spider.

It is easy sometimes to wonder whether our governments care about anything except money; yet they refuse to put a monetary value on those aspects of life that lend enchantment (Mary Dejevsky, Quality of life has a price. The frackers should pay it, 17 October). A beautiful view is one of these; so is peace and quiet. So is the ability to keep one’s windows open at night.

These blessings are disappearing at great speed, as the skies fill up, and as lorries, cars and machines are added to our beloved landscapes. We are told that “those affected by fracking” might be compensated, but I do not believe that many people would rather have £10,000 than the peace and quiet, and the grassy view that will vanish, with their clean drinking water, as the frackers appear. It is generally noise that provides the majority of council complaints. For example, between January and September 2014, councils in the UK received 200,220 noise complaints, almost half the total number (Report, 18 March 2014).
