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.

US energy shakeup continues as solar capacity set to triple
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.

Review: Sonic Sea at the Environmental Film Festival
![](https://62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com/files/142622/width496/image-20161021-1763-1cdxsxc.jpg)
The sounds of the sea are associated with tranquillity and relaxation. People go to the beach to enjoy the soothing crash of ocean waves. But beneath the surface of the ocean, there is no peace and quiet for whales and dolphins.
The increasing use of the sea for human activities has resulted in a dramatic rise in noise levels. A new film, Sonic Sea, screening at the Environmental Film Festival Australia, shows that the ocean is not at all silent. It highlights our emerging understanding of the consequences of human-produced noise pollution in the ocean.
The documentary, directed by Michelle Dougherty and Daniel Hinerfeld, brings together beautiful cinematography and audio effects that draw viewers into this ethereal underwater world.
When mammals returned to the sea, they evolved to use sound as their primary way to navigate through their environment. This is because sound travels further and more efficiently through water than air.
For marine mammals, using sound to communicate, and to see (echolocate), is invaluable. But this dependence by marine mammals on underwater sound is now a trap; they have nowhere to escape the increasing underwater noise.
Where does the noise come from?The film presents three major sources of human-produced noise in the ocean: shipping, seismic exploration, and military sonar.
Shipping noise is acoustically overwhelming the ocean, doubling every decade with no hint of slowing. Not only is the number of ships increasing, but they are also getting bigger and carrying more containers.
This noise reduces the distance over which animals can communicate with one another, forcing them to compete with increasing background noise.
Finding mates would become more difficult meaning whales may miss out on the opportunity to breed.
Alarmingly, this increasing noise has been shown to cause stress in the northern right whales, one of the world’s most endangered marine mammals. The situation can be likened to being in the audience at a rock concert without being able to leave.
Mass stranding events of beaked whales have been linked to the use of military sonar. It appears that these whales have a marked behavioural response to some types of sonar. This may be why the whales strand at times when military sonar has been used. This has raised serious concerns for the navy about whether, and where, this type of sonar can be used.
Even though seismic explosions, used by oil and gas companies, do not cause direct harm to whales, the blasts do drive them away from the area. Fish, on the other hand, are deafened by these detonations and we have seen a long-term drop in numbers with the prolonged use of seismic air guns.
Turning down the volumeThe film presents various solutions to help reduce the amount of noise that is generated and the impact caused to these vulnerable animals.
Our heavy reliance on ships for the transport of goods means we cannot simply stop their movement. But it is possible to implement quieter and more efficient engines and propellers to reduce noise.
Critical habitat such as feeding and breeding grounds, as well as migratory routes, need to be identified and protected.
When whales are present, harmful activities such as seismic blasts and sonar need to stop.
The film concludes by leaving viewers with the question: what would the world look like if we don’t reduce our impacts? It raises the question of sustainability and the legacy we will leave for future generations once we are gone.
Sonic Sea is screening at the Environmental Film Festival Australia in Sydney on Saturday October 22, 2016.

Islabikes' radical new plan means you may never need to buy your child a bike again
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.
After coking plant's last gasp, a feast for nature
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.

We are approaching the Trumpocene, a new epoch where climate change is a big scary conspiracy | Graham Readfearn
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.

Hundreds of snow leopards being killed every year, report warns
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.

Australia joins bid to outlaw large-scale commercial and 'scientific' whaling
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.
