Prime minister defends fossil fuel as part of Australia’s energy mix as critical Senate bloc opposes ‘green lawfare’ changes

Malcolm Turnbull has declared coal will be part of Australia’s energy mix for “many, many, many decades to come” as a critical Senate bloc expressed opposition to so-called “green lawfare” changes designed to limit the legal standing of conservation groups in court proceedings.

Turnbull made the bullish observation about coal during a radio interview in Brisbane on Tuesday morning, arguing that the effort to “strangle the Australian coal industry is not going to do anything to reduce global greenhouse gas emissions”.

Earth is distinguished from all other known planets by the presence of a warm, salty ocean that covers over 70% of its surface. The ocean puts food on the table, provides jobs, and underpins trillions of dollars of economic activity worldwide.

In a new report for the WWF, we looked in particular at how Melanesia’s ocean economy is fairing. Melanesians - the people of Fiji, New Caledonia, Papua New Guinea, Solomon Islands and Vanuatu - have a strong social and cultural dependency on the sea.

Faced with looming global challenges such as climate change and food security, the region is a now at a crossroads.

Why is Melanesia’s ocean important?

Based on conservative estimates, the annual “gross marine product” of the Melanesian region – the equivalent of a country’s annual gross domestic product (GDP) – is estimated to be at least US$5.4 billion. This is broadly equivalent to the combined GDPs of Fiji and the Solomon Islands, making it the third largest economy in the region.

Melanesia’s ocean assets, including fisheries and marine habitats, as well as “services” such as coastlines and carbon absorption, are valued at a minimum of US$548 billion.

Ocean assets provide a range of valuable goods and services, including food and raw materials, income, energy, tourism, recreation, cultural practices, protection from storms, and climate regulation. Maintaining healthy ocean assets is therefore vital for the future of the Melanesian region.

However, it is becoming increasingly clear that Melanesia’s ocean and its precious assets are under mounting pressures. These changes will have implications for the environment, food security, employment and the well-being of human communities both within the region and beyond.

In some isolated circumstances, eroding the ocean assets of Melanesia may lead to short-term benefits for certain places and people. However, any positive changes are likely to be short lived and specific to one country or another. For instance, declining catches for some species of tuna are already predicted for Papua New Guinea and the Solomon Islands by 2035.

Climate change will add to the challenge. Future climate projections include rising air and sea surface temperatures, increases in annual and seasonal rainfall, increasing intensity of tropical cyclones, rising sea levels and increasing acidity of the ocean.

Reports of coral bleaching, fish kills and severe Tropical Cyclone Winston that affected the Melanesian region this year, coupled with high rates of sea-level rise are a clear reminder of the difficulties the region faces amid a rapidly changing climate.

Melanesia at the crossroads

Melanesian leaders are now faced with two pathways for the management of its marine resources and securing ecological and economic prosperity.

The first is the current trajectory of increasing pressure on ocean assets coupled with inadequate policy and/or action. This pathway will lead to a degraded future in which opportunities for the inhabitants of the Melanesian region will be significantly diminished.

The second trajectory is to move towards a sustainable and inclusive blue economy. Such an approach will ensure that coastal assets contribute to the true prosperity and resilience of the Melanesian region long into the future.

The oceans and coastal ecosystems are vital to life on Earth, and achieving the UN’s Sustainable Development Goals (SDGs) without the services the oceans provide will be challenging, if not impossible.

While Goal 14 focuses specifically on the ocean, a sustainable and inclusive blue economy will incorporate and build strategies that are important to meeting many of the other SDGs. This priority is interlocked with other international priorities, such as achieving a safe climate through the recent Paris Agreement.

It would also provide social and economic benefits for current and future generations by contributing to food security, reducing poverty, livelihoods, income, employment, health, safety, equity and political stability.

In addition, it would also restore, protect and maintain the diversity, productivity, resilience, core functions and intrinsic value of marine ecosystems – the natural capital upon which its prosperity depends.

Ways forward

Pacific leaders have already generally acknowledged the importance of working together across the region.

Examples include work on inshore fisheries management and sustainable development.

There have been some successes such as the Vessel Day Scheme, which limits the number of days that fishers can fish, and community coastal management such as locally managed marine areas. These are helping to guide spatial planning and integrate conservation and sustainable use of marine resources.

In light of Melanesia’s eroding ocean asset base, the new report acknowledges the commitments already made and sets out a clear set of measures that Melanesian leaders can adopt. These build on traditional environmental stewardship to protect the region’s natural coastal and ocean assets.

While our new report puts the spotlight on Melanesia and presents an economic case for greater management, the perspectives are equally applicable to the Pacific region as a whole, given that the ocean connects the island nations, rather than separates them.

The economic analysis for this report was led by The Boston Consulting Group (BCG).

Jade Fitzpatrick says reports of attacks often make them sound ‘bigger and scarier’ and he will be surfing again within days

Jade Fitzpatrick is still in shock a day after escaping the jaws of a 2.7-metre great white off the New South Wales north coast, but he says reporting of attacks should be kept in perspective and netting beaches is not the solution.

The 36-year-old surfer suffered three puncture wounds to his upper thigh when his surfboard bore the brunt of the attack off a beach between Suffolk Park and Broken Head near Byron Bay on Monday morning.

You may have heard the statistic that we waste about a third of the food we buy. What you might not have heard is that there are now many animals that actually depend on this food waste.

Geoff Cousins is a former Howard government advisor and president of the Australian Conservation Foundation and says all Australians should be able to have their day in court over the country's natural resources.

The Prime Minister has expressed concern over 'systematic, well-funded' environmental campaigns targeting developments such as the Adani coal mine in Queensland.

Being a “locavore” means choosing food that is grown locally, and is one way that you can help ensure there is more food to go around.

To feed the predicted nine billion people in the world in 2050, the world will need to produce 70-100% more food. This unprecedented increase in food production will require substantial changes in soil management, land cultivation, and crop production.

This cannot be achieved without technological advances that increase crop yield and reduce the need to use nitrogen-based fertilisers. The question is how this can be achieved sustainably, while also tackling climate change.

This is where “eating local” comes in.

What is eating local?

The primary reason why eating local is good for the planet is the reduction in energy resources required for transport and storage. Generally, the further a food has travelled from “paddock to plate”, the greater its impact on the environment. This is because of fuel used in transport and increased greenhouse gas emissions used for refrigerated storage.

The mode of transport matters too. Transporting food by air generates 177 times more greenhouse gases than shipping it.

The global food system lets us eat food from all over the world, all year round. But food miles impact adversely on the nutritional quality of fresh foods, and on the environment.

Yet while eating foods grown close to where we live makes planetary sense, farmers markets and foods grown more sustainably (organically) often carry a price premium, and seem to be targeted to a trendy and wealthy demographic.

The lack of a definition of “eating locally” also raises questions of how to incorporate organic and fair trade produce within the larger sustainability movement, and how to support developing nations.

Global supply chains place great demands on ecosystems and natural resources, and large distances between where food is produced and consumed is often seen as evidence of an unsustainable food system. However, this is not always as straightforward as it appears.

Take the case of seafood. Australia is in the enviable position of having been ranked in the top five countries for fisheries management and the majority of commercial fish stocks in Australia are assessed as sustainable.

However, 72% of seafood consumed in Australia is imported. Surprisingly, there is little difference between the carbon footprint of meals made using imported seafood compared with those of three domestic wild-caught fish.

10 tips for eating local

So given that eating local can be tricky, here are 10 tips:

1: Become familiar with foods that are grown or produced locally and what time of the year they are available. Seasonal food guides are available from some fruit markets and online such as one developed for south-east Queensland.

2: Look for local farmers markets, community gardens, food co-operatives and community supported agriculture schemes. Green Connect is one example of a community-supported agriculture scheme operating in the Illawarra region of New South Wales. In some states such as Tasmania, a thriving food tourism culture may encourage consumers to eat locally but this concept has not been replicated in other parts of the country.

3: Grow your own fruit and vegetables and keep chickens in your own backyard, or get involved in your local community garden, and trade produce with neighbours.

4: Read the labels of packaged foods. The new “Made in Australia” labelling on foods makes it easier to determine where the food (and its individual components) has been grown, processed and packaged.

5: Choose less processed foods. Generally, the more processed a food is, the more energy and water it requires in the production process. Replace junk food with fresh fruit, nuts and vegetables.

6: Take the Eco Friendly Food Challenge and get some friends to join you.

7: Cook meals using fresh ingredients rather than purchasing ready-made meals.

8: Ask your food retailers and manufacturers about the origin of the food you are buying. Locate fruit and vegetable retailers, butchers, delicatessens and fishmongers who sell food produced locally.

9: Limit your intake of alcohol and purchase locally-grown alcohol with the lowest food miles possible. If you enjoy a particular beer or wine, contact the manufacturer to learn about their environmental policies and to advocate for more environmentally friendly production methods.

10: The Fair Food Forager app allows you to search for food outlets that adhere to fair and sustainable practices.

Creating consumer demand for more locally and sustainably produced food is being led not only by food champion Jamie Oliver’s Food Revolution, but also by our very own Australian Youth Food Movement, whose organisers are passionate about improving the food supply for future generations.

Fin whales | Weighing passengers | Traffic | Quakers | Angela Carter

In the report on the stranding of a fin whale on Holkham Beach (Rare fin whale washed up on Norfolk beach, 22 October), Dr Ben Garrod of Anglia Ruskin University states that “you never get [fin whales] in the North Sea”. I certainly saw one six miles off Hartlepool in about 1978. There was flat calm and hot sun, and there were great rafts of seabirds. The whale jumped clear of the water six or seven times, mostly through the rafts of birds. I estimated the whale to be as long as our 12 metre yacht. Later I mentioned this to a fisherman at Hartlepool, who told me that this only happened on days like I described. He was obviously familiar with the sight.

• Hawaiian Airways’ plan to weigh their passengers (Report, 24 October) is a good idea. Skybus planes from Cornwall to the Scilly Isles have always done so. As you board the eight-seater Islander, they tell each passenger (by name) where to sit so the weight is evenly distributed. The process is very discreet; the check-in desk incorporates scales. On one occasion, our combined weight was so great that the luggage had to travel separately on the next flight. They never divulged who had caused the overload, but we knew!

Carbon dioxide reached 400 parts per million on average during 2016 and will not dip below that mark for many generations, experts say

The world is in a new era of “climate change reality”, with carbon dioxide in the atmosphere reaching a symbolic threshold which it will not fall below for many generations, scientists have said.

In 2015, for the first time, carbon dioxide levels in the atmosphere were at 400 parts per million (ppm) on average across the year as a whole, the World Meteorological Organisation’s (WMO) annual greenhouse gas bulletin reveals.

To paraphrase Donald Trump, this is radical atmospheric change and Republicans won’t even mention the words

Climate change’s impacts on extreme weather and society are becoming increasingly clear and undeniable. While we are making progress in solving the problem, we’re still moving too slowly, and one of the two political parties governing the world’s strongest superpower continues to deny the science. This led astrophysicist Katie Mack to make the following suggestion, related to a common refrain from Donald Trump and Republican Party leaders:

Maybe governments will actually listen if we stop saying "extreme weather" & "climate change" & just say the atmosphere is being radicalized
