Clexit calls for withdrawal from climate treaties, rejects the conclusions of 97% of climate science experts and 95% of economics experts

Brexit support and climate denial have many similarities. Many Brexit Leave campaign leaders also deny the dangers of human-caused climate change. Older generations were more likely to vote for the UK to leave the EU and are more likely to oppose taking action on climate change; younger generations disagree, and will be forced to live with the consequences of those decisions. On both issues there’s also a dangerous strain of anti-intellectualism, in which campaigners mock experts and dismiss their evidence and conclusions.

With Brexit, the Leave campaign won the vote, and the UK economy is already feeling the consequences. As Graham Readfearn reported, a new group called “Clexit” (Climate Exit) has formed in an effort to similarly withdraw countries from the successful international climate treaty forged last year in Paris. As the group describes itself:

Scientific survey found all reefs had been affected by high sea surface temperatures, with up to 90% of coral colonies bleached in some areas

More than 60% of coral in reefs in the Maldives has been hit by “bleaching” as the world is gripped by record temperatures in 2016, a scientific survey suggests. 

Bleaching happens when algae that lives in the coral is expelled due to stress caused by extreme and sustained changes in temperatures, turning the coral white and putting it at risk of dying if conditions do not return to normal.

Palm oil producer was stripped of its certification in March 2016 after failing to meet environmental standards, reports BusinessGreen

Palm oil supplier IOI Group has had its certificate for sustainable palm oil reinstated by the Roundtable for Sustainable Palm Oil (RSPO), after it was judged to have fulfilled the body’s demands to improve its environmental performance.

In a statement issued last Friday, the RSPO said the palm oil supplier would be re-instated with its certificate from Monday.

Jackie Trad says action is needed to prevent harm to the Great Barrier Reef as study shows tens of thousands of hectares cleared in catchment areas

Hundreds of thousands of hectares of land have been cleared in Queensland, a new study has found, after a surge led by cattle graziers under relaxed laws that the state government is seeking to overturn.

A state science department study on land cover released on Sunday found 296,000 hectares of land was cleared in 2014-15, more than a third of it in Great Barrier Reef catchments.

Scotland’s industries and farmers must cut energy, greenhouse gas emissions and resource use as waste overtakes pollution as the major environmental threat, says head of regulator

Scotland’s environment agency has warned the country’s industries and farmers that their waste and inefficiency is now the biggest threat to the environment, overtaking pollution.

In a marked shift in strategy, the regulator’s chief executive, Terry A’Hearn, will urge businesses, farmers and manufacturers to adopt a “one planet prosperity” policy designed to cut their energy use, greenhouse gas emissions, waste and resource use.

The only way the UK could have another runway without breaking climate change laws would be to increase prices

When the government’s Airports Commission endorsed the expansion of Heathrow last year it was challenged to explain how the UK could expand its airports without breaking climate change laws that limit greenhouse gas emissions.

It was a reasonable question. Like most countries, the UK has a tough emissions target for 2050 and, even though aviation has been given an easy ride compared with other industries, the sector is on course to exceed its generous limit. That’s the case even without adding a new runway. Increasing the number of flights from the UK would put the target further out of reach.

Marshwood Vale, Dorset The meadow is a waving, dancing, tawny-pink shimmer of grasshopper song

The landscape is dense, dark green and silent. Acres of monocrop ryegrass fields, grown for silage, lie empty, penned between tall hedges and thick, mostly neglected, stands of oak, ash, alder and hazel. The damp clay in the Vale nurtures straight-growing trees of monster size, once prized by the navy. Eager to keep the trees, 16th- and 17th-century farmers would coppice everything, even young oaks, to spoil them for shipbuilding. Today these old oaks can be identified by their strange shapes, branches growing out in sudden clumps from stunted trunks.

Along the line of the ploughed-out bridleway, the ground underfoot is hard and lumpy, the grass a scanty layer over stones and cracked clay. I miss the overgrown footpath through the hedge and have to go back. Pushing aside brambles and nettles, I climb the first wobbly stile and the blackthorn closes around and above me, making a low passageway. Three, four steps with twigs catching at my hair, over the second stile and out into a different environment.

Volumes rose and spot prices rebounded in a tight market, with Origin receiving a "humbling" price for its gas exports as the oil price falls.

One Nation senator-elect and climate denier Malcolm Roberts has raised a number of questions on climate science and empirical evidence. Here are some answers...

South Australia is becoming a magnet for world-leading storage investments that surely signal the permanent demise of fossil fuel "base-load" generation in the electricity system. And by tapping into home solar and storage systems, utilities are changing the way people think about energy.

There’s more to summer smog than traffic, heating and industry. Hydrocarbons are chemically reactive and can form thousands of other pollutants

The contribution of diesel exhaust to summer smog has been a topic of hot debate over the last six years.

Not all air pollution comes directly from sources such as traffic, heating and industry. Pollutants are also created from chemical reactions in the atmosphere. This is especially true in summer when stronger sunlight provides extra energy to drive the chemistry. During this July’s hot weather, air drifted over France and the UK, accumulating pollutants that then reacted in the sunshine. The resulting summertime smog reached six on the UK government’s ten point warning scale.

Female dingo in Oxley Wild Rivers NP, New South Wales Guy Ballard, CC BY-NC

From cats and foxes to goats and cane toads, invasive animals are one of Australia’s biggest environmental problems. Over the past few weeks, one Queensland council has been trying a new approach to controlling goats on an offshore island: introducing dingoes from the mainland.

But since dingoes were moved to Pelorus Island to kill goats, passions have overflowed for and against.

Queensland RSPCA chief executive Mark Townend was notable among the opposition. He stressed that his organisation is not against feral animal control, but opposes the “very cruel method” of using dingoes to achieve it.

Some people have also strongly objected to the implantation of poison capsules, containing sodium fluroacetate, into the Pelorus Island dingoes. This is intended to kill them after they have killed the goats.

In a rapidly changing world, people are trying new ways to save wildlife and help the environment. These strategies are forcing us to ask new, and sometimes difficult, ethical questions.

Changing world

Humans have created a global patchwork of degraded environments. Australia has the world’s worst mammal extinction record, as well as booming populations of invasive herbivores and ongoing problems with native habitat loss.

When it comes to managing invasive animals, Australians have often been quick to use lethal “pest” control. Methods include poisoning, trapping and shooting for livestock and wildlife protection, in attempts to reduce populations until impacts reach acceptable levels.

This approach does not sit well with many Australians and it has become common to see vocal opposition to wildlife culling programs that are perceived as indiscriminate, unnecessary or unacceptably cruel.

At the same time, there is increasing support for reintroducing native predators to help fix environmental problems.

Some experts in Australia have suggested that Australia should use dingoes to control invasive herbivores, red foxes and feral cats, following the example of our North American counterparts.

Some call it “rewilding”. Others simply see it as biological control. Regardless, a range of private and public land managers believe that dingoes should be Australia’s primary agents of ecosystem restoration.

Putting aside the debate about the likely success of such schemes, the issue of public acceptance remains. Proponents claim that using dingoes for environmental benefit is both “virtuous” and “free”. But the objections to the use of dingoes for feral goat control shows that there is still widespread dissatisfaction with getting dingoes to do our dirty work.

The ethics of killing

Every control technique has a welfare impact on wildlife, causing some pain and suffering.

We can measure objectively how well a technique works, but assessments of humaneness are always subjective. When people choose lethal control, we condemn animals to death.

Although it has been marketed as “compassionate conservation”, using dingoes for pest control means that other animals will be hunted, maimed and killed. This applies to the animals we want removed, such as goats, as well as to other wildlife that shares the habitat.

The future of using dingoes and other predators as pest controllers hinges on whether or not the public finds it acceptable. Do people draw a line between “natural” ways of killing invasive animals (with dingoes), and more artificial means (such as poison)?

We know, for instance, that dingo attacks can be extremely distressing for livestock producers.

Queensland RSPCA’s opposition to the Pelorus Island trial doesn’t mean an end to rewilding, but it is significant. It reminds us that welfare is an important issue for invasive animal control, regardless of whether humans or animals are doing the killing.

Some people find the notion of dingo-based pest control acceptable, even appealing, but others do not. Just as society expects that we carefully assess the use of poisons, traps or bullets, so too we should consider the welfare impacts of outsourcing death to dingoes and making them our tools for ecosystem management.

Ecosystem services – the natural processes that allow Earth to sustain life and provide us with everything we have and see – are facing an uncertain future.

Between 1997 and 2011, the global value of ecosystem services declined by up to US$20 trillion per year as a result of changing land use. To put that in context, the world’s entire GDP is currently just under US$74 trillion.

Our research shows that, in the Asia-Pacific region, this downward trend is likely to continue unless there are significant policy changes. By 2050, we predict that ecosystem service values could drop by 34% from their 2011 base value of US$13 trillion.

But, more optimistically, we also forecast that ecosystems could grow in value by 24% by mid-century, if policies are put in place to safeguard these crucial environmental values.

An Asian century (of ecosystems)

The Asia-Pacific region has historically followed the global trend in ecosystem depletion. But the future doesn’t have to be like the past. The decisions we make as a society will determine what our world will look like in that future.

With that in mind, our research focused on a range of land-use scenarios to try to forecast the consequences of various social, environmental and economic policies.

We used these scenarios to derive estimates of land-use change (urban, cropland, forest, grassland, wetland, desert), population, GDP and other variables such as inequality up to the year 2050. Changes in total value of ecosystem services in these scenarios were estimated to be due to two factors: the change in area covered by each ecosystem type; and the change in the “unit value” – the total value of all the marketed and non-marketed ecosystem services, per area, per year of each ecosystem type due to degradation or restoration.

In the Asia-Pacific region, Afghanistan shows the greatest potential losses and gains, as do other countries that are more susceptible to desertification. At the same time, these countries also have the greatest potential for reversing land degradation.

On the other hand, in this region, countries like Japan and New Zealand have the least potential for fluctuations in their ecosystem service values. This is because they are already highly developed and potentially have more stable climates.

Australia’s prospects

Australia, second only to China in ecosystem services value, also shows an extensive range of values among our four scenarios. Starting with a terrestrial ecosystem services value of US$3.4 trillion per year in 2011 (roughly three times Australia’s GDP that year), we forecast that by 2050 ecosystem services could grow in value by as much as 21%, or decrease by up to 29%.

This translates to either a gain of US$700 billion per year or a loss of US$980 billion per year – a figure that’s not far short of Australia’s current annual GDP.

The scenarios used incorporate a range of world views and policies, and the impacts of these on the entire, integrated system, including population, energy use, equity, environmental change, climate change and more. Our research features a country-by-country breakdown of the outcomes of each scenario, although it is impossible to separate out the impact of individual policies, especially given the differences in each country.

The consequences and solutions

The loss of ecosystem services will be felt most strongly by the poorest in any society, as they depend most directly on ecosystem services. They are the first to feel the effects when those services begin to disappear, and the least able to replace or ameliorate the loss. Increasing ecosystem services, on the other hand, would increase sustainable human well-being.

Around the world, the focus on ecosystem services has been growing quickly. Recent major policy reforms in this direction include a White House memo directing US federal agencies to incorporate ecosystem services into their planning, investment and regulations.

Other countries have also begun to incorporate ecosystem services in their policies. The European Union has mandated all member countries to produce national ecosystem service assessments, for use in policy and decision-making.

At the international level, the United Nations has set up an Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, analogous in structure and function to the Intergovernmental Panel on Climate Change. The international Ecosystem Services Partnership has also been established to co-ordinate and facilitate the exchange of information and expertise across the world.

We have taken ecosystem services for granted for far too long. The UN Sustainable Development Goals, adopted last year by all UN countries, include specific calls to promote sustainable use of terrestrial ecosystems, to halt and reverse land degradation, to ensure clean water and food security, as well as to safeguard life both on land and in the oceans.

If we are taking these goals seriously, we need to put natural capital and ecosystem services “on the books” as a major contributor to sustainable well-being.

As Patrick Barkham says (Postcards from the hedge, 2 August) austerity is responsible for wild roadsides. But this is only partly so. Plantlife has for years campaigned for roadside verges to be left uncut until flowers have dropped their seeds, which can be as late as August or September. One cut can be ideal, with the proviso that visibility is maintained for road users. Dorset county council is following such guidelines and is experimenting with stripping topsoil to reduce fertility and introducing yellow rattle to inhibit vigorous grass growth. It is hoped that other local authorities will introduce such measures into their roadside maintenance schedules to help wildflowers that have been pushed from farmlands to the margins.
