Gaping chasm between Coalition's climate mantra and the real debate | Lenore Taylor

The Guardian - Sat, 2016-09-03 09:28

Like the emperor with no clothes, Josh Frydenberg is continuing the grand parade, insisting that Australia is making a successful transition

Almost every group with a financial, intellectual or ethical interest in salvaging a workable climate policy is now deep in an urgent debate about how Australia can break a decade of policy paralysis. Everyone except the Turnbull government, that is.

The debate, involving big business, small business, investors, the government’s own independent climate advisers, academics, environmentalists, the welfare lobby and the unions, is predicated on the obvious conclusion that our policy – as it stands – cannot deliver the cuts to greenhouse emissions that are domestically necessary and which Australia has promised internationally.

How a microbead ban could help solve a massive problem – video

The Guardian - Sat, 2016-09-03 03:50

A poll from Greenpeace found that almost two thirds of people in the UK think microbeads should be banned. The beads are already banned in the US, but are still common in Britain. They’re a threat to marine life and potentially to humans, but the poll also found that most people don’t actually know what they are

UK government to ban microbeads from cosmetics by end of 2017

The Guardian - Sat, 2016-09-03 02:49

Found in beauty products, tiny pieces of plastic which can harm marine life will be banned from sale in the UK from the end of 2017, government will announce

Tiny pieces of plastic in personal beauty products, that end up in the oceans and are swallowed by marine life, will be banned from sale in the UK by the end of 2017, the government is to announce on Saturday.

The move comes just days after MPs called for a ban on so-called microbeads, and sees the UK following in the footsteps of the US, which has banned them beginning in mid-2017. More than 357,000 people signed a petition calling for a UK ban, and environment groups welcomed the news of the ban.

Hawaii and other big marine protected areas 'could work against conservation'

The Guardian - Sat, 2016-09-03 01:36

The Papahānaumokuākea marine park created by Barack Obama could end up as just a ‘paper park’, argue US and UK marine experts

British and US marine scientists say that the race to designate ever-bigger marine national parks in remote parts of the world could work against conservation.

In an commentary timed to coincide with President Obama’s announcement of the huge extension of a marine park off Hawaii, the authors argue that the creation of very large marine protection areas (Vlmpas) may give the illusion of conservation, when in fact they may be little more than “paper parks”.

Pacific Islands fail to agree plan to protect tuna

The Guardian - Fri, 2016-09-02 20:40

Countries from around the Pacific Ocean met to discuss ways of protecting the shrinking supplies but were unable to come to any agreement, officials say

Pacific island states and countries failed on Friday to strike a deal to protect shrinking supplies of tuna and adopt cutbacks following a regional conference, officials said, sparking condemnation from conservationists.

The Pacific Ocean is the world’s largest tuna fishing ground, accounting for almost 60% of the global catch.

Otter pups gambol on the rocks

The Guardian - Fri, 2016-09-02 14:30

Isle of Gigha, Argyll The young otters were having a good time, splashing and paddling and roughhousing; we were enchanted

Having abandoned our bikes by the gate, we follow a cattle trodden path between walls of bracken down to where field meets sand. The silver slip of a beach is postcard perfect, a flawless bleached-bone white. But close up it is busy with the telltale trails of recent visitors: speechmark hoofprints of cattle and the flatfoot waddle of whooper swans, each webbed imprint as large as my palm.

No people, though, which was our aim. We set up camp upon a grassy flat, and wander along the foreshore, picking through tidewrack and pocketing curios: a mermaid’s purse, torn and discarded, scraps of net, pebbled glass.

It's time to speak up about noise pollution in the oceans

The Conversation - Fri, 2016-09-02 13:55

Ask most people about pollution, and they will think of rubbish, plastic, oil, smog, and chemicals. After some thought, most folks might also suggest noise pollution.

We’re all familiar with noise around us, and we know it can become a problem – especially if you live near an airport, train station, highway, construction site, or DIY-enthusiast neighbour.

But most people don’t think that noise is a problem under water. If you’ve read Jules Verne’s Twenty Thousand Leagues Under the Sea you might imagine that, maelstroms excepted, life is pretty quiet in the ocean. Far from it.

When we put a hydrophone (essentially a waterproof microphone) into the water, no matter where in the world’s oceans, it’s never quiet. We hear wind blowing overhead and rain dropping onto the ocean surface – even from hundreds of metres deep. In Australian waters we can also detect the far-off rumbles of earthquakes and the creaking of Antarctic ice thousands of kilometres away.

Wet and noisy

Water is much denser than air, so its molecules are packed tighter together. This means that sound (which relies on molecules vibrating and pushing against one another) propagates much further and faster under water than in air.

This also applies to human-produced sound. Under water we can hear boats and ships and even aeroplanes. Large vessels in deep water can be detected tens of kilometres away. We can be far offshore doing fieldwork, the only people around, with nothing in sight but water in any direction. Yet when we switch the engines off and put a hydrophone into the water, we hear ship noise. Sometimes, whole minutes later, the vessel we heard might appear on the horizon.

Seafarers have known about another source of sound for thousands of years: marine life. Many animals produce sound, from the tiniest shrimp to the biggest whales. Many fish even communicate acoustically under water – during the mating season, the boys start calling. Whales do it, too.

Light doesn’t reach far under water. Near the surface, in clear water, you might be able to peer a few metres, but in the inky depths you can’t see at all. So many marine animals have evolved to “see with sound”, using acoustics for navigation, for detecting predators and prey, and for communicating with other members of their species.

The thing is that man-made sound can interfere with these behaviours.

The effects of noise on marine animals are similar to those on us. If you’ve ever been left with ringing ears after a rock concert, you’ll know that loud noise can temporarily affect your hearing or even damage it permanently.

Noise interferes with communication, often masking it. Can you talk above the background noise in a busy pub? Long-term exposure to noise can cause stress and health issues — in humans and animals alike.

Excessive noise can change marine creatures' habits, too. Like a person who decides to move house rather than live next door to a new airport, animals might choose to desert their habitat if things get too noisy. The question is whether they can find an equally acceptable habitat elsewhere.

There is a lot more research still to be done in this field. Can we predict what noises and vibrations might be released into the marine environment by new machinery or ships? How does sound propagate through different ocean environments? What are the long-term effects on marine animal populations?

One positive is that even though noise pollution travels very fast and very far through the ocean, the moment you switch off the source, the noise is gone. This is very much unlike plastic or chemical pollution, and gives us hope that noise pollution can be successfully managed.

We all need energy, some of which comes from oil and gas; most of our consumer goods are shipped across the seas on container vessels; and many of us enjoy eating seafood caught by noisy fishing boats, some of which even use dynamite to catch fish. We want to protect our borders, making naval operations a necessity. Then there’s the ever growing industry of marine tourism, much of it aboard ever-bigger cruise ships which need large ports in which to berth.

There are a lot of stakeholders in the marine environment, and all speak a different language, all make different claims, and all make noise. Knowing precisely how much noise they make, and how it affects marine life, will help to ensure our oceans and their resources last well into the future.
