Vanuatu’s top lawyer has called out the United States for “bad behavior” after newly inaugurated President Donald Trump withdrew the world’s biggest historic emitter of greenhouse gasses from the Paris Agreement for a second time.

The Pacific nation’s Attorney-General Arnold Loughman, who led Vanuatu’s landmark International Court of Justice climate case at The Hague last month, said the withdrawal represented an “undeniable setback” for international action on global warming.

“The Paris Agreement remains key to the world’s efforts to combat climate change and respond to its effects, and the participation of major economies like the US is crucial,” he told BenarNews in a statement.

The withdrawal could also set a “troubling precedent” regarding the accountability of rich nations that are disproportionately responsible for global warming, said Loughman.

“At the same time, the US’ bad behavior could inspire resolve on behalf of developed countries to act more responsibly to try and safeguard the international rule of law,” he said.

“Ultimately, the whole world stands to lose if the international legal framework is allowed to erode.”

Trump’s announcement on Monday came less than two weeks after scientists confirmed that 2024 was the hottest year on record and the first in which average temperatures exceeded 1.5 degrees Celsius above pre-industrial levels.

Agreed to ‘pursue efforts’
Under the Paris Agreement adopted in 2015, leaders agreed to “pursue efforts” to limit warming under the 1.5°C threshold or, failing that, keep rises “well below” 2°C  by the end of the century.

Fiji Prime Minister Sitiveni Rabuka said on Wednesday in a brief comment that Trump’s action would “force us to rethink our position” but the US president must do “what is in the best interest of the United States of America”.

Other Pacific leaders and the Pacific Islands Forum (PIF) regional intergovernmental body have not responded to BenarNews requests for comment.

The forum — comprising 18 Pacific states and territories — in its 2018 Boe Declaration said: “Climate change remains the single greatest threat to the livelihoods, security and wellbeing of the peoples of the Pacific and [we reaffirm] our commitment to progress the implementation of the Paris Agreement.”

Trump’s executive order sparked dismay and criticism in the Pacific, where the impacts of a warming planet are already being felt in the form of more intense storms and rising seas.

Jacynta Fa’amau, regional Pacific campaigner with environmental group 350 Pacific, said the withdrawal would be a diplomatic setback for the US.

“The climate crisis has for a long time now been our greatest security threat, especially to the Pacific,” she told BenarNews.

A clear signal
“This withdrawal from the agreement is a clear signal about how much the US values the survival of Pacific nations and all communities on the front lines.”

New Zealand’s former Minister for Pacific Peoples, Aupito William Sio, said that if the US withdrew from its traditional leadership roles in multilateral organisations China would fill the gap.

“Some people may not like how China plays its role,” wrote the former Labour MP on Facebook. “But when the great USA withdraws from these global organisations . . . it just means China can now go about providing global leadership.”

Analysts and former White House advisers told BenarNews last year that climate change could be a potential “flashpoint” between Pacific nations and a second Trump administration at a time of heightened geopolitical competition with China.

Trump’s announcement was not unexpected. During his first term he withdrew the US from the Paris Agreement, only for former President Joe Biden to promptly rejoin in 2021.

The latest withdrawal puts the US, the world’s largest historic emitter of greenhouse gases, alongside only Iran, Libya and Yemen outside the climate pact.

In his executive order, Trump said the US would immediately begin withdrawing from the Paris Agreement and from any other commitments made under the UN Framework Convention on Climate Change.

US also ending climate finance
The US would also end its international climate finance programme to developing countries — a blow to small Pacific island states that already struggle to obtain funding for resilience and mitigation.

A fact sheet published by the Biden administration on November 17, which has now been removed from the White House website, said that US international climate finance reached more than US$11 billion in 2024.

Loughman said the cessation of climate finance payments was particularly concerning for the Pacific region.

“These funds are essential for building resilience and supporting adaptation strategies,” he said. “Losing this support could severely hinder ongoing and future projects aimed at protecting our vulnerable ecosystems and communities.”

George Carter, deputy head of the Department of Pacific Affairs at the Australian National University and member of the COP29 Scientific Council, said at the centre of the Biden administration’s re-engagement with the South Pacific was a regional programme on climate adaptation.

“While the majority of climate finance that flows through the Pacific comes from Australia, Japan, European Union, New Zealand — then the United States — the climate networks and knowledge production from the US to the Pacific are substantial,” he said.

Climate actions plans
Pacific island states, like all other signatories to the Paris Agreement, will this year be submitting Nationally Determined Contributions, or NDCs, outlining their climate action plans for the next five years.

“All climate actions, policies and activities are conditional on international climate finance,” Carter said.

Pacific island nations are being disproportionately affected by climate change despite contributing just 0.02 percent of global emissions, according to a UN report released last year.

Low-lying islands are particularly vulnerable to rising sea levels and extreme weather events like cyclones, floods and marine heatwaves, which are projected to occur more frequently this century as a result of higher average global temperatures.

On January 10, the World Meteorological Organisation (WMO) confirmed that last year for the first time the global mean temperature tipped over 1.5°C above the 1850-1900 average.

WMO experts emphasised that a single year of more than 1.5°C does not mean that the world has failed to meet long-term temperature goals, which are measured over decades, but added that “leaders must act — now” to avert negative impacts.

During Cyclones Hale and Gabrielle the poor management of exotic plantations in Aotearoa New Zealand — primarily pine — has again led to extensive damage in Tairāwhiti.

Critical public infrastructure destroyed; highly productive agricultural and horticultural land washed away or buried; houses, fences and sheds knocked over; people’s lives and dreams upended; people dead.

The impacts on natural ecosystems are still unknown, but there will have been extensive damage in terrestrial, freshwater and marine environments. Similar damage occurred during storms in June 2018 and July 2020.

• READ MORE: Cyclone Gabrielle triggers more destructive forestry ‘slash’ — NZ must change how it grows trees
• Global supply chains are devouring what’s left of Earth’s unspoilt forests

While heavy rainfall and flooded rivers are a major factor, it is sediment and slash from plantation harvesting that has been the cause of most of the damage.

Slash is the woody material (including large logs) left after clear-fell harvesting of commercial forests.

Landslides in harvested sites pick up the material and carry it downstream, causing significant damage. All the evidence from Cyclone Gabrielle shows that much of the damage was caused by radiata pine slash.

The legacy of poor land management
Sediment and slash from exotic tree harvesting sites were established as major factors in the damage that occurred during the June 2018 Tolaga Bay storm in recent court cases taken by Gisborne District Council.

Five plantation companies were found guilty and fined for breaching resource consent conditions relating to their management practices.

Multiple groups have called for an inquiry into the way plantation harvest sites are being managed in Tairāwhiti and elsewhere.

But given the severity and ongoing nature of these impacts, is it not time we move beyond focusing on management practices and address the broader underlying issues that have triggered this situation?

These ultimate causes are complex but primarily revolve around historic poor land management decision-making and human-induced climate change.

‘East Coast disaster’: Environmental group calls for inquiry into forestry practices https://t.co/pjTVIiy0Cf pic.twitter.com/MQYkVZCMAY

— nzherald (@nzherald) January 13, 2023

Among the key drivers of the current problems in Tairāwhiti are the large areas of exotic tree plantations that were established with government support after the devastation of Cyclone Bola.

But this devastation also reflects earlier poor land management decisions to clear native forest off steep, erodible hill country in the late 19th and early 20th centuries, which was also encouraged by the government of the day.

Looming climate change
The other underlying driver of the disaster is human-induced climate change. Atmospheric CO2 levels are now 150 percent above pre-industrial levels and climates are changing rapidly with new and unprecedented events becoming the norm.

While increasing global temperatures are the most obvious feature of human-induced climate change, it is the increasing frequency and intensity of extreme weather events that are having the biggest impacts on people and the environment.

It is essential that we hold the forestry sector accountable in Tairāwhiti and elsewhere. But we also need to urgently address the underlying causes because no matter how strict harvesting rules are, storm events are going to occur with increasing frequency and intensity.

Time for urgent action
With more than 40 years experience researching forest ecology and sustainable land management in Aotearoa, I believe there are four key areas where we need to urgently act to address these issues.

1. As a country we need to rapidly reduce greenhouse gas emissions and rapidly increase the draw-down of CO2 out of the atmosphere. These are national issues and not confined to Tairāwhiti but as a nation we seem to be sleepwalking in our response to the climate emergency.
2. We need a comprehensive catchment-by-catchment assessment across all of Tairāwhiti (and likely other areas of Aotearoa) to identify those plantations that are located in the wrong place in terms of potential harvesting impacts. There should be no further harvesting in Tairāwhiti plantations until this exercise has been completed. We also need to identify those areas that currently lack plantations but should never be planted in exotic tree crops (for any purpose).
3. The government then needs to buy out the current owners of these plantations and embark on a programme of careful conversion to native forest. This will come at a cost, but it needs to be done. We already have models for this in Tairāwhiti where the Gisborne District Council has started converting pine forests in its water supply catchment to native forests.
4. Finally, we need to establish substantially more native forests throughout all Tairāwhiti, and Aotearoa more generally, to help build resilience in our landscapes.

The consequences of short-term thinking
For too long we have been fixated in Aotearoa with maximising short-term returns from exotic tree crops without thinking about long-term consequences. The legacies of this fixation are now really starting to impact us as the climate emergency exposes the risks that poorly sited and managed exotic tree crops pose.

And we are now making the same mistakes with exotic carbon tree crops, again leaving unacceptable legacies for future generations to deal with because of a focus on short-term financial gains.

Exotic tree plantations have dominated forest policy in Aotearoa and we urgently need to shift this to a focus on diverse native forests.

Our native rainforests provide so many benefits that exotic tree crops can never provide.

They are critical for the conservation of our native biodiversity, providing habitat for a myriad of plant, animal, fungal and microbial species. They also regulate local climates, enhance water quality and reduce erosion. This helps sustain healthy freshwater and marine environments.

Native replanting initiatives championed by charities like Pure Advantage need to be the primary focus of forest policy in Aotearoa now and in the future.

This year was another huge one for Local Democracy Reporting, with our reporters at the forefront of uncovering some of the biggest stories in their regions.

Felix Desmarais in Rotorua exposed hitherto secret plans by the council to revoke the reserve status of seven council reserves, paving the way for new housing to be built on them, including social housing.

It became a major election issue with residents using the ballot to choose candidates opposed to the plan, which was subsequently canned by the new council.

• READ MORE: Other Local Democracy Reporting stories on APR

Steve Forbes covered the chaos created by understaffed and overstretched Emergency Departments, with a deep dive in to the death of a patient who visited Middlemore Hospital.

He was first with a damning independent report that found the ED was “an unsafe environment for both patients and staff”.

It was a year of climate change-induced severe weather, and LDR reporters produced numerous stories on how councils were coping, or not, when it came to putting back together what Mother Nature had torn apart.

Flooding this year continued to represent an existential threat to Westport after the devastating inundation seen last year as well. Brendon McMahon’s stories have reflected the reality on the ground, such as the predicament faced by residents on Snodgrass Road who had been left out of a proposed flood protection scheme.

Nelson clean-up
Nelson reporter Max Frethey has kept readers up to date as that city deals with its own clean-up after devastating downpours in August, which left the city with a repair bill of between $40 million and $60 million, the biggest in its 160-year history.

The weather kept Marlborough’s Maia Hart busy this year as well in a region with communities still cut off or with limited access due to damage caused a year ago.

But it was her story on the resilience of elderly Lochmara Bay resident Monyeen Wedge that really captured readers’ attention. Living alone, she went three days without power and was forced to live off canned food.

The pandemic and the response of health authorities and councils continued to be an area of inquiry for LDR in 2022, and none more so than Moana Ellis in Whanganui.

While high vaccination rates amongst pākehā protected thousands from the worst affects of the Omicron wave, it was a battle for DHBs to reach many Māori, who already had a distrust of health authorities. Moana’s reporting ensured these communities were not forgotten.

In one of LDR’s most read stories of 2022, Alisha Evans uncovered the extent of bureaucratic overreach in Tauranga when through traffic was discouraged on Links Ave with the help of a fine. A glitch led to infringements being issued to drivers living as far away as the South Island who had never even visited the city.

Reporters have documented the good and the bad of people’s interactions with vulnerable ecosystems. North Canterbury’s David Hill shone a light on the wonton destruction of endangered nesting birds in the region’s braided river beds by 4WD enthusiasts.

Community efforts
While Mother Nature was the winner following a series of stories from Taranaki’s Craig Ashworth on community efforts to protect dwindling stocks of kaimoana, which finally resulted in a two-year long rāhui.

The national roll out of flexible median barriers, aka “cheesecutters”, caused consternation in Whakatāne where Diane McCarthy talked to police who said they would struggle to pass drivers on their way to emergencies and farmers driving slow-moving tractors worried about extra levels of road rage from slowed-up motorists.

The dire state of the country’s water infrastructure is magnified in places like Wairarapa, with its small ratepayer base and decades old pipes and sewage treatment. There was no better illustration of this than Emily Ireland’s reporting on Masterton’s use of its Better Off funding where it was pointed out a mum was using a council provided portaloo to potty train her toddler because sewage was backing up in the town system whenever there was heavy rain.

The human impact of decisions around water infrastructure was also brought in to sharp relief in Ashburton reporter Jonathan Leask’s excellent reporting. He took up the cause of a couple and their three children who were shut out of moving in to their dream home due to high nitrate levels limiting the building of any more septic tanks.

One of the biggest changes around council tables this year was the election of Māori ward candidates, with half of all councils now having these. Northland’s Susan Botting has been first out of the blocks reporting on the new dynamics at play, starting with Kaipara mayor Craig Jepson’s ban on karakia to open meetings. The ban was hastily reversed, but led to the largest hikoi in Dargaville for some time.

As with all of LDR’s reporters, choosing just one stand out story from the many fine pieces published throughout the year is almost impossible. None more so than Tairāwhiti reporter Matthew Rosenberg.

But no wrap of 2022 would be complete without mention of his story on bulldozer driver Hamish Pryde. The 65-year-old helped save Wairoa from a dangerously high river by negotiating already badly flooded paddocks and opening up a sand bar so the river could drain out to sea.

As Matthew says, “not all heroes wear capes, some drive bulldozers”.

As the New Zealand government prepares to deal with a looming omicron outbreak, this will not be the only major issue it will have to tackle this year.

The year 2022 will be important for environmental and climate action.

Several key developments are expected throughout the year, both in New Zealand and internationally, focusing on climate change and biodiversity — and how these crises overlap with the impacts of the covid-19 pandemic.

• READ MORE: Biodiversity: world leaders are negotiating new targets to protect nature by 2030 – the story so far

In February and early April, the Intergovernmental Panel on Climate Change (IPCC) will publish the next two parts of its Sixth Assessment (AR6).

These reports will provide the basis for global negotiations at the next climate summit scheduled to be held in Egypt in November.

The February report will focus on impacts and adaptation and the April report on mitigation of climate change. Together, they will assess the global and regional impacts of climate change on natural ecosystems and on human societies, as well as opportunities to cut emissions.

They will identify points of particular vulnerability, consider the practicalities of technological innovations and weigh the costs and trade-offs of low-carbon opportunities. Both reports will present a definitive statement of where impacts of climate change are being felt and what governments and other decision makers can do about it.

Multiple crises
Climate change tends to dominate headlines about the environment. But biodiversity loss and accelerating rates of species extinction pose an equal threat to our economies, livelihoods and quality of life.

#ClimateChange – why 2022 matters

Look out for #IPCC #ClimateReports this year as the @UN outlines ten key global events in 2022 that will shape critical conversations and policies around #climatechange.https://t.co/6u8zE9ujRE

— IPCC (@IPCC_CH) January 12, 2022

A UN Global Assessment Report on biodiversity and ecosystem services predicts the loss of one million species during the coming decades. It foresees serious consequences for our food, water, health and social security.

New Zealand is not immune from this global crisis. About one third of our species are listed as threatened.

In April, the UN Biodiversity Conference in Kunming, China, will launch a new global biodiversity framework to guide conservation and sustainable management of ecosystems until 2030.

Expect to see intense negotiations on the current draft framework as states try to balance the need to address the underlying causes of biodiversity loss, without endangering economic priorities, including post-covid recovery.

New Zealand’s plan to cut emissions
In May, the government is expected to release its first emissions reduction plan (ERP), in response to the Climate Change Commission’s advice on how New Zealand can meet its domestic and international targets.

The plan will set out policies and strategies to keep the country within its emissions budget for 2022-25 and on track to meet future budgets.

Under the Climate Change Response Act 2002, the government is required to set emissions budgets for every three to four-year period between 2022 and 2050 and to publish emissions reduction plans for each.

The first plan looks likely to come at a difficult time for the economy. Businesses have already contended with covid-related lockdowns and uncertainty and may soon be challenged by staffing shortages in the wake of the omicron outbreak.

It will be tricky to balance the need for significant action to reduce emissions while keeping business and the wider community on board. Expect a wide-ranging plan with sector-specific strategies for transport, energy, industry, agriculture, waste and forestry, but little detail on agriculture.

Half a century since first environment summit
In 1972, the UN Conference on the Human Environment took place in Stockholm, Sweden. It was the first international conference to make the environment a major issue.

Fifty years on, in June this year Stockholm +50 will mark a half-century of global environmental action, and refocus world leaders’ attention on the “triple planetary crisis” of climate, biodiversity and pollution.

The aim is to accelerate progress on the UN’s Sustainable Development Goals, the Paris Agreement and the global biodiversity framework, while making sure countries’ covid-19 recovery plans don’t jeopardise these. Expect growing demand for more global recognition of a “human right to a healthy environment” to leverage more effective environmental action.

On the domestic front, the national adaptation plan (NAP) is due in August. This will set out how the government should respond to the most significant climate change risks facing Aotearoa.

These risks range from financial systems to the built environment and have already been identified in the first national climate change risk assessment. Public consultation will take place in April and May.

The decade of action
The UN’s annual climate summit, COP27, will take place in Sharm el-Sheikh, Egypt, in November. Last year, COP26 drew unparalleled public attention and generated some positive new climate pledges.

One major success was an agreement that nations revisit and strengthen their nationally determined contributions by the end of 2022. But the summit was generally criticised for failing to secure commitments from high-emitting countries to keep global temperatures from climbing beyond 1.5℃.

The overarching aim to “keep 1.5℃ alive” will be more urgent than ever. A particular concern is how effectively civil society will be able to bring pressure to bear on governments.

Protests and activities are likely to be significantly limited by the Egyptian host government.

In the build-up to COP27, expect significant pressure on big polluter states to deliver more ambitious commitments to cut emissions, but also less flamboyant and free protests in Egypt.

The UN has called 2020-2030 the “decade of action”. The chance remains to avoid runaway climate change, protect biodiversity and stabilise our ecosystems. It’s imperative that this year, the third of this decade, is one that really counts.

In 1992, 1700 scientists warned that human beings and the natural world were “on a collision course”. Seventeen years later, scientists described planetary boundaries within which humans and other life could have a “safe space to operate”.

These are environmental thresholds, such as the amount of carbon dioxide in the atmosphere and changes in land use.

Crossing such boundaries was considered a risk that would cause environmental changes so profound, they genuinely posed an existential threat to humanity.

• READ MORE: Worried about Earth’s future? Well, the outlook is worse than even scientists can grasp
  

This grave reality is what our major research paper, published today, confronts.

In what may be the most comprehensive evaluation of the environmental state of play in Australia, we show major and iconic ecosystems are collapsing across the continent and into Antarctica. These systems sustain life, and evidence of their demise shows we are exceeding planetary boundaries.

We found 19 Australian ecosystems met our criteria to be classified as “collapsing”. This includes the arid interior, savannas and mangroves of northern Australia, the Great Barrier Reef, Shark Bay, southern Australia’s kelp and alpine ash forests, tundra on Macquarie Island, and moss beds in Antarctica.

We define collapse as the state where ecosystems have changed in a substantial, negative way from their original state – such as species or habitat loss, or reduced vegetation or coral cover – and are unlikely to recover.

The good and bad news
Ecosystems consist of living and non-living components, and their interactions. They work like a super-complex engine: when some components are removed or stop working, knock-on consequences can lead to system failure.

Our study is based on measured data and observations, not modelling or predictions for the future. Encouragingly, not all ecosystems we examined have collapsed across their entire range. We still have, for instance, some intact reefs on the Great Barrier Reef, especially in deeper waters. And northern Australia has some of the most intact and least-modified stretches of savanna woodlands on Earth.

Still, collapses are happening, including in regions critical for growing food. This includes the Murray-Darling Basin, which covers around 14 percent of Australia’s landmass. Its rivers and other freshwater systems support more than 30 percent of Australia’s food production.

The effects of floods, fires, heatwaves and storms do not stop at farm gates; they’re felt equally in agricultural areas and natural ecosystems. We shouldn’t forget how towns ran out of drinking water during the recent drought.

Drinking water is also at risk when ecosystems collapse in our water catchments. In Victoria, for example, the degradation of giant Mountain Ash forests greatly reduces the amount of water flowing through the Thompson catchment, threatening nearly five million people’s drinking water in Melbourne.

This is a dire wake-up call — not just a warning. Put bluntly, current changes across the continent, and their potential outcomes, pose an existential threat to our survival, and other life we share environments with.

In investigating patterns of collapse, we found most ecosystems experience multiple, concurrent pressures from both global climate change and regional human impacts (such as land clearing). Pressures are often additive and extreme.

Take the last 11 years in Western Australia as an example.

In the summer of 2010 and 2011, a heatwave spanning more than 300,000 sq km ravaged both marine and land ecosystems. The extreme heat devastated forests and woodlands, kelp forests, seagrass meadows and coral reefs. This catastrophe was followed by two cyclones.

A record-breaking, marine heatwave in late 2019 dealt a further blow. And another marine heatwave is predicted for this April.

These 19 ecosystems are collapsing: read about each

What to do about it?
Our brains trust comprises 38 experts from 21 universities, CSIRO and the federal Department of Agriculture Water and Environment. Beyond quantifying and reporting more doom and gloom, we asked the question: what can be done?

We devised a simple but tractable scheme called the 3As:

• Awareness of what is important
• Anticipation of what is coming down the line
• Action to stop the pressures or deal with impacts.

In our paper, we identify positive actions to help protect or restore ecosystems. Many are already happening. In some cases, ecosystems might be better left to recover by themselves, such as coral after a cyclone.

In other cases, active human intervention will be required – for example, placing artificial nesting boxes for Carnaby’s black cockatoos in areas where old trees have been removed.

“Future-ready” actions are also vital. This includes reinstating cultural burning practices, which have multiple values and benefits for Aboriginal communities and can help minimise the risk and strength of bushfires.

It might also include replanting banks along the Murray River with species better suited to warmer conditions.

Some actions may be small and localised, but have substantial positive benefits.

For example, billions of migrating Bogong moths, the main summer food for critically endangered mountain pygmy possums, have not arrived in their typical numbers in Australian alpine regions in recent years. This was further exacerbated by the 2019-20 fires. Brilliantly, Zoos Victoria anticipated this pressure and developed supplementary food — Bogong bikkies.

Other more challenging, global or large-scale actions must address the root cause of environmental threats, such as human population growth and per-capita consumption of environmental resources.

We must rapidly reduce greenhouse gas emissions to net-zero, remove or suppress invasive species such as feral cats and buffel grass, and stop widespread land clearing and other forms of habitat destruction.

Our lives depend on it
The multiple ecosystem collapses we have documented in Australia are a harbinger for environments globally.

The simplicity of the 3As is to show people can do something positive, either at the local level of a landcare group, or at the level of government departments and conservation agencies.

Our lives and those of our children, as well as our economies, societies and cultures, depend on it.

We simply cannot afford any further delay.

By TJ Aumua in Suva

Hydrothermal vents have been compared as the ocean equivalent of the earth’s volcanoes. They are a treasure trove of precious minerals and home to unique ocean life.

The rich ecosystems in the vents have scientists eager to gain more knowledge about them, as they face threats of disruption from deep-sea mining interests.

Hydrothermal vents are formed when the movement of the Earth’s plates split open, releasing chemically enriched water, forcing emerged peaks in the ocean’s surface.

Marine species that are developed to live in each vent’s specific ecosystem also face the danger of industrial mining.

Marine researcher and Schmidt Ocean Institute communications manager Carlie Wiener spoke to Asia-Pacific Report in Suva where she was a guest speaker as part of a series of seminars hosted by the Pacific Centre for Environment and Sustainable Development (PaCE-SD) at the University of the South Pacific.

She says hydrothermal vent communities are still largely unexplored.

“Because the deep ocean is so dark, the species use hydrogen-sulfide and the process of chemosynthesis to produce energy,” Wiener says. “This is unlike land animals where they use sunlight and photosynthesis to produce energy.”

The Schmidt Ocean Institute (SOI) is currently on a 28-day expedition researching hydrothermal vent sites between Fiji and Tonga.

The SOI team will use a remotely operated vehicle (ROV) that is able to travel up to 3000m to the seafloor to photograph species and take environmental measurements of the vents.

Scientists are hoping the research will provide new insights into volcanic and tectonic activity in the Pacific basin, the ecology of hydrothermal vent species, and data on the impact of deep-sea mining to establish policies and protocols for the future.

Weiner said there is need for more research to happen in the Pacific with the institute receiving many proposals addressing oceanography exploration in the region.

Earlier this year, SOI researchers studied the effect of greenhouse emissions and its link with low oxygen zones in the Pacific Ocean.

Communities in the region are encouraged to get involved in the explorations.

Students and researchers can send in proposals for future expeditions to the SOI website.

“Our diving explorations are also livestreamed,” says Weiner.

“So someone here in Fiji who will never get to see 2000m below the surface, can watch it – it’s right in their backyard, happening in real time.”

Ami Dhabuwala and Pacific Media Watch contributing editor TJ Aumua are in Fiji on a two-week “Bearing Witness” climate change journalism project with the University of the South Pacific.

• The hole in the ocean – the Mariana Trench

Recurring climate change patterns have not only impacted on the communities and landscapes of Fiji but also caused significant damage to the seascape of one of the nation’s pristine wild places – Vatu-i-ra Island.

The director of the Fiji Programme for Wildlife Conservation Society, Dr Sangeeta Mangubhai, has been studying the coral reefs in the Vatu-i-ra seascape, located between Fiji’s two large islands, Viti Levu and Vanua Levu.

Dr Mangubhai’s report on the impact of cyclone Winston on Vatu-i-ra revealed that the strong winds and waves affected coral reefs up to 30m below the surface of the sea.

“Vatu-i-ra Island has a regionally significant seabed population and there is just no vegetation on the leaves so we’re not sure what it is going to do to the seabed population because they need shade and shelter to live there.”

Coral regeneration is a slow process and the report shows that frequent extreme weather events combined with other effects of climate change could take the reefs decades to recover.

“It’s hard because these reefs are already suffering from issues like overfishing… but now they’ve received stress to their physiology, coral loss, coral damage, stress of sea surface temperatures – that combination has led to corals probably aborting their reproduction this year,” Dr Mangubhai says.

Oxfam New Zealand’s senior campaigns and communications specialist Jason Garman says climate changed has caused rising sea temperatures and an increase in pH levels known as ocean acidification. As Garman explains, this phenomenon has led to developments such as coral bleaching.

‘Garden of Eden’
“Coral reefs are the Garden of Eden of life in the sea…this is where the vast majority of the biodiversity will be, so when the coral reefs die then all of those fish no longer have the food source they need and the fish die out or move to another area where they can live.

“Climate change is driving ocean acidification, shellfish are no longer able to create their shells because the water is so acidic that it disintegrates the shell this is also what is driving coral bleaching,” Garman says.

Dr Mangubhai’s research has also identified coral bleaching in the Vatu-i-ra seascape, with some areas experiencing up to 20 percent of bleaching as a result of increased ocean temperatures from the El Niño cycle.

Garman says the trends of El Niño are increasing in severity as a result of climate change and says scientists expect this phenomenon to get worse.

“El Niño has been going on for eons and the problem is that El Niño is caused by a rise in the surface temperature of the oceans in the southern Pacific and the higher the temperature the stronger the weather event is.

“In the past we had very strong cyclones perhaps every 50 years to 100 years but what we’re seeing right now is that those once in a lifetime storms are becoming nearly an annual event.”

Increasing storms
UNICEF Suva’s communication specialist Alice Clements says an increased prevalence of storms is something that involves climate adaptation.

“Since 1970 there have been 11 category five cyclones and two of those have been in the span of 12 months with cyclone Pam in Vanuatu and cyclone Winston in Fiji so we know that things are changed. Fiji has done a phenomenal response to this emergency, they’ve been incredibly organised and they’ve done it quickly.

“In the past something like this would’ve been a shock or something out of the blue but these days they can anticipate that there might be a strong storm coming at some point in their life.”

Climate change adviser for the Secretariat of the Samoa based Pacific Regional Environment Programme (SPREP) Herman Timmermans says communities and the ecosystems they depend on for everyday goods and services and livelihoods will be more severely impacted on by more intense cyclones and recovery times will be longer.

Timmermans says that the socio-economic and environmental benefits derived are also much greater.

Although Dr Mangubhai’s report did not cover a visual census of the coral reef fish populations, it revealed that semi-pelagic fish and sharks seemed largely unaffected.

Also based on data collected on how the Australian Great Barrier Reef’s recovery from previous cyclone damage, Dr Mangubhai expects the productivity of fisheries to decrease.

Fisheries damage
“The fisheries in the area are valued at more than F$24 million (NZ$16.7 million) – there will obviously be a decline from that, but we don’t know by how much until we understand fully the scale of damage to fisheries in the region.

“Fish need time for the corals to come back to provide that habitat for them to move around and find new homes.”

She says although cyclone Zena — which hit Fiji earlier this month — was a relatively milder category two, it was expected to move the rubble around and cause more abrasions to the corals.

Dr Mangubhai says while rehabilitation of coral reefs is expected to be very expensive, the best option to minimise further impact to the region’s sea life is reduce fishing pressure on the reefs. But she says that is a difficult proposition considering fish is the staple diet of local populations.

“There’s a real challenge between communities now – they need to continue to fish for food security and some of them are going to be under more pressure to fish out their resources for money.

“Then it’s also got a bleaching event sitting on top of a cyclone event so it’s even more than they normally experience and they’re going to need space to recover and it’s really going to depend on how much we can reduce that pressure for the next couple of years, give those corals a chance to come back before we can come back to the same level to be explored again.”

Activists are suing the Indonesian government in a bid to stop development they say will devastate the last remaining area on earth where Sumatran tigers, rhinoceroses, orangutans and elephants live together in the wild.

The world-renowned Leuser Ecosystem in the heart of the Sumatran jungle in Aceh is at risk of being destroyed by a government plan to allow roads in the area and by potential concessions for mining and plantations, campaigners say.

In the latest stage of a nearly two-year bid to have the plan retracted, nine representatives of the group Gerakan Rakyat Aceh Menggugat launched a civil lawsuit at the Central Jakarta District Court.

“[The plan] effectively dissolves protection of much of Aceh’s remaining tropical rainforests, whitewashing crimes of the past, and paving the way for a new wave of catastrophic ecological destruction,” GeRAM representative Farwiza Farhan​ said.

The short-term profits from the developments would not benefit the people of Aceh, she said.

“They are after quick immediate short-term gains, but the consequences will be borne by the rest of the community.

Crucial for survival
The Sumatran Orangutan Conservation Programme says the Leuser Ecosystem is crucial for the survival of the Sumatran tigers, rhinoceroses, elephants and orangutans.

“If you lose Leuser you lose all four of those species guaranteed,” Sumatran Orangutan Programme conservation manager Ian Singleton said.

“The … plan basically ignores the existence of the Leuser Ecosystem. It opens up massive areas of lowland forests to potential new concessions for plantations, mining, timber even, and it also legalises many roads that have been cut through the forest … and roads alone are enough to send these species to extinction.”

The lawsuit is against both the Aceh government, which activists claim is acting unlawfully by not including the protected ecosystem in the plan, and the Ministry of Home Affairs, which they claim has failed to protect the Leuser Ecosystem.

The group claims the Ministry of Home Affairs indicated the plan would need to include protection of the ecosystem but has failed to take necessary action.

They are hoping to have the Aceh government redraw the plan and provide protection for the Leuser Ecosystem and proper environmental analysis.

The Leuser Ecosystem covers more than 2.6 million hectares across the provinces of Aceh and Northern Sumatra and is regarded by conservationists as one of the richest areas of tropical rainforest in Southeast Asia. Within the ecosystem is Gunung Leuser National Park, which is listed as a World Heritage Site.

Jewel in crown
“The Leuser Ecosystem is a jewel in the crown of the world’s rainforests – and it’s unbelievable that the Aceh government isn’t taking stronger steps to help protect it,” Professor Bill Laurance, of James Cook University, says.

“In a world in which invaluable ecosystems are vanishing almost daily, the Leuser is becoming one of the most alarming environmental tragedies unfolding anywhere.”

The geographically diverse area consists of lowland rainforest, peatlands, mountain ranges, lakes and nine substantial rivers. In addition to providing a habitat to a number of endangered wildlife species it is also a life system for the more than 4 million people, and helps protect the area from natural disasters such as flooding and landslides.

Professor Laurance has been campaigning to have the Leuser Ecosystem listed as a World Heritage Site.

“Virtually anywhere else on the planet, the Leuser would be protected as a World Heritage Site – a crucial element of our global heritage. I think the best hope is that the Indonesian federal government might be persuaded to intervene in Aceh, just as we saw happen in Australia with the establishment of World Heritage sites in Tasmania and the Queensland Wet Tropics. I haven’t seen much evidence that the Aceh government on its own is going to the swayed to protect Leuser.”

The court will order a mediation between the two parties before the litigation proceeds.
