Arctic ice falls to record winter low after polar 'heatwaves'

The Guardian - Thu, 2017-03-23 04:00

Extent of ice over North pole has fallen to a new wintertime low, for the third year in a row, as climate change drives freakish weather

The extent of Arctic ice has fallen to a new wintertime low, as climate change drives freakishly high temperatures in the polar regions.

The ice cap grows during the winter months and usually reaches its maximum in early March. But the 2017 maximum was 14.4m sq km, lower than any year in the 38-year satellite record, according to researchers at the US National Snow and Ice Data Centre (NSIDC) and Nasa.

Thames Water hit with record £20m fine for huge sewage leaks

The Guardian - Wed, 2017-03-22 23:37

Massive fine reflects change in sentencing as previously low penalties failed to deter water firms from polluting England’s rivers and beaches

Thames Water has been hit with a record fine of £20.3m after huge leaks of untreated sewage into the Thames and its tributaries and on to land, including the popular Thames path. The prolonged leaks led to serious impacts on residents, farmers, and wildlife, killing birds and fish.

The fine imposed on Wednesday was for numerous offences in 2013 and 2014 at sewage treatment works at Aylesbury, Didcot, Henley and Little Marlow, and a large sewage pumping station at Littlemore.

Honduras, where defending nature is a deadly business

The Guardian - Wed, 2017-03-22 21:00

In the first in a series, Yale Environment 360 reports from Honduras where Berta Cáceres fought to protect native lands and paid for it with her life – one of hundreds of victims in this disturbing global trend

They came for her late one evening last March, as Berta Cáceres prepared for bed. A heavy boot broke the back door of the safe house she had just moved into. Her colleague and family friend, Gustavo Castro, heard her shout, “Who’s there?” Then came a series of shots. He survived. But the most famous and fearless social and environmental activist in Honduras died instantly. She was 44 years old. It was a cold-blooded political assassination.

Berta Cáceres knew she was likely to be killed. Everybody knew. She had told her daughter Laura to prepare for life without her. The citation for her prestigious Goldman Environmental prize, awarded in the US less than a year before, noted the continued death threats, before adding: “Her murder would not surprise her colleagues, who keep a eulogy – but hope to never have to use it.”

Global warming is increasing rainfall rates | John Abraham

The Guardian - Wed, 2017-03-22 20:00

A new study looks at the complex relationship between global warming and increased precipitation

The world is warming because humans are emitting heat-trapping greenhouse gases. We know this for certain; the science on this question is settled. Humans emit greenhouse gases, those gases should warm the planet, and we know the planet is warming. All of those statements are settled science.

Okay so what? Well, we would like to know what the implications are. Should we do something about it or not? How should we respond? How fast will changes occur? What are the costs of action compared to inaction? These are all areas of active research.

Princess Anne has strongly backed genetically modified crops, saying she would grow them on her own land and that GM livestock would be a “bonus”.

Her stance puts her sharply at odds with her brother Prince Charles, who has long opposed GM food and has said it will cause the “biggest disaster environmentally of all time”.

Water spins into a million bubbles filled with light

The Guardian - Wed, 2017-03-22 15:30

The Long Mynd, Shropshire The sound of Light Spout waterfall seems, at first, to be all roar and splash

To stand in the stream under the Light Spout is to be drenched in sound and mesmerised by light. Through a narrow cleft, water gathered from bogs on the plateau of the Long Mynd plunges 20ft over the rock face into a shallow pool before roiling down the stream of Carding Mill valley.

The sky is grey, there is bite left in the season and a fine drizzle lowers between hills. Shale ledges break the flow of water; it spins into a million bubbles filled with light so that, on a day like this, it looks like the ghostly Lady in White, a shimmering apparition.

Film review: A Plastic Ocean shows us a world awash with rubbish

The Conversation - Wed, 2017-03-22 14:37

We live in a world of plastic. Shopping bags, drink bottles, your toothbrush and even your clothes are among the everyday items made from plastic. But plastic isn’t fantastic, and neither is the current state of our environment.

Humans have been mass-producing plastic since the 1950s. We produce hundreds of millions of tonnes of plastic every year and production is only increasing. Unfortunately, most of it is used only once and then thrown away.

Only a small proportion of plastic is recycled. The majority ends up in landfill or, in the worst case scenario, our oceans.

A Plastic Ocean is a documentary film directed by the Australian journalist Craig Leeson. It dives into and investigates the devastating impacts that plastic has caused to our environment, especially our marine life.

What starts off as an adventure to film the blue whale, the largest animal on the planet, leads to the shocking discovery of a thick layer of plastic debris floating in the middle of the Indian Ocean. Craig, alongside Tanya Streeter, a world record-breaking free diver and environmental activist, then travel across the globe to report on the havoc caused by decades of plastic use.

The film presents beautiful shots of the marine environment. This contrasts with footage of heavily polluted cities and dumps full of plastic rubbish. The juxtaposition between these images sends the message that our actions and choices can severely impact the planet. Throughout the film, experts are interviewed to provide further insight into some of the problems derived from plastic.

Impacts of plastic use

Plastic is so widely used because it is durable and cheap. Unfortunately, this durability is the same quality that makes it so detrimental to the environment. Most plastics do not break down chemically. Instead, they break into smaller and smaller pieces that can persist in the environment for an extensive period of time.

Because it is so affordable, developing countries use plastics extensively. However, many regions lack proper waste management, and much of the rubbish is washed into the ocean when it rains. As a result, a large percentage of all plastics in the ocean are due to only a handful of countries. Scientists estimate that more than 5 trillion pieces of plastic are currently floating in our oceans.

Throughout the film, we are shown footage of numerous marine species that have been affected by plastic debris. Marine animals and sea birds often mistake floating plastic for food. Large pieces of plastic, when eaten, can obstruct the animals’ digestive tracts of the animals, essentially starving them to death.

When smaller “microplastics” are ingested, toxins are released and become stored in their tissue. These toxins accumulate up the food chain and can eventually end up on our dinner tables. The consumption of the contaminated seafood can cause many health problems including cancer, immune system problems, and even childhood developmental issues. This is a major problem, as almost a fifth of the world’s population relies on the ocean for their primary source of protein. Society’s huge appetite for plastic is literally poisoning us.

The future of plastics

There is no quick fix for a problem that has grown hugely over the past few decades. The use of plastics is so ingrained in society that it is all but impossible to eliminate them completely.

The film does, however, offer various strategies that can be implemented to reduce the impact of plastics.

Ideally, avoid plastic-containing products as much as possible. Avoid single-use plastic products and recycle whatever you can. Local governments also need to implement a refund scheme for the return of plastic bottles to incentivise recycling.

For unrecyclable plastics, new technology has been developed to convert them into fuel, providing a second life for those plastics.

It is up to us to embrace these changes and move away from the plastic culture. We need to get this problem under control, as it will only become worse as the human population increases. Our marine animals deserve to live in a blue ocean, not a plastic soup.

A Plastic Ocean is touring internationally, including screenings in Brisbane on March 25 and Cairns on March 27.
