Emmanuel Macron Says The World Is Losing The Fight Against Climate Change: 'We're Not Moving Quick Enough'

The Independent - Mythili Sampathkumar

Emmanuel Macron has said that the world is “losing the battle” against climate change and issued a plea to the leaders of wealthy countries: “We’re not moving quick enough. We all need to act.”
Mr Macron was speaking at the One Planet summit in Paris, a meeting of 50 countries to which the US President was not invited.
But in a light-hearted nod to Donald Trump, who has called climate change a “hoax”, the tag line for the summit was “Make Our Planet Great Again”.
Mr Macron said the US was not willing to “join the club” on combating climate change, he told Time.  As part of the summit, 18 mostly US-based scientists will win paid opportunities to live and conduct climate-related research in Europe, away from the climate scepticism of Mr Trump.
Other attendees to the summit included Mexican President Enrique Pena Nieto, Theresa May and the secretary-general of the United Nations, Antonio Guterres.
France announced a raft of 12 non-binding commitments, from a $300m pledge to fight desertification to accelerating the transition towards a decarbonised economy. But there was no headline promise likely to reassure poor nations on the sharp end of climate change that they will be better able to cope.
Developed countries have pledged to provide $100bn (£75bn) a year to poorer countries, every year after 2020 – when the Paris Agreement, a global accord to curb greenhouse gas emissions and limit global warming to 2C, comes into force.
The funds were supposed to go towards adapting poorer countries’ infrastructures and economies to be more climate resilient, particularly in the event of a natural disaster. But specific details about financial pledges did not make it into the main text of the Paris Agreement in 2015, as governments called for flexibility.

Now, there are fears that countries are not getting even close to that figure for the first year. The Organisation for Economic Cooperation and Development (OECD) estimates only about $68bn (£51bn) has been collected.
Also in focus is how public and private financial institutions can mobilise more money and how investors can pressure corporate giants to shift towards more ecologically friendly strategies.
More than 200 institutional investors with $26 trillion in assets under management said they would step up pressure on the world’s biggest corporate greenhouse gas emitters.
Part of the reason to keep up momentum on fighting climate change is the vacancy in action and financing left by the US government under Mr Trump.

The US withdrew a $2bn pledge to the Green Climate Fund, one of the myriad pots set up for developing countries to receive aid money.
In June, Mr Trump ordered the start of the official withdrawal of the US from the Paris Agreement, after former President Barack Obama was obliged to use an executive order to join the deal in 2016 to bypass climate deniers in Congress.
The US remains the only country not in the Paris Agreement after previous holdouts Nicaragua and Syria joined the rest of the world.
And the US actively promoted the use of fossil fuels at a UN climate change meeting last month.
Industry representatives from coal, oil, gas and nuclear power companies like Peabody Energy, nuclear engineering firm NuScale Power, and Tellurian, a liquefied natural gas exporter, were prominently featured during the event.
During the panel, Mr Trump’s international energy issues adviser George D Banks said it was “controversial only if we chose to bury our heads in the sand”.
“Without question, fossil fuels will continue to be used, and we would argue that it’s in the global interest to make sure when fossil fuels are used that they be as clean and efficient as possible,” Mr Banks said.
However, the US private sector and state governments – like Governor Jerry Brown representing California – have not been left out of the One Planet summit. 
Over a thousand governors, mayors, and CEOs in the US have pledged to keep up the commitments outlined in the Paris Agreement despite the federal government’s inaction.

Qld Premier Annastacia Palaszczuk Seeks To Veto Adani Loan

The Australian

Adani protesters may have just got what their hearts desired. Picture: AAP
Re-elected Queensland Labor Premier Annastacia Palaszczuk has written to Prime Minister Malcolm Turnbull to veto a federal loan to the Adani coal project in Queensland’s Galilee Basin.
In one of her first acts after she was officially sworn in this morning, Ms Palaszczuk has followed through on the shock announcement she made during the election campaign to block a loan from the Northern Australia Infrastructure Facility to the Indian conglomerate to build a common-user rail line in the basin.
“My government provides formal notification for the Commonwealth that financial assistance should not be provided to Adani for the North Galilee Basin Rail Project,” Ms Palaszczuk’s letter to Mr Turnbull reads.
“As such, the government is exercising its veto right under section 13(4) of the Investment Facility Mandate in response to the Adani loan application.”
An Adani spokesman said the company was still committed to Queensland despite the veto, and insisted the Queensland government was still supportive of its Carmichael coal mine proposal for the Galilee Basin.
“We congratulate Premier Palaszczuk on her government’s election and look forward to working closely and cooperatively with the state and federal governments and regulatory authorities as we get on with the job of making all of our projects a reality,” the spokesman said.
“Adani Australia currently employs over 800 people and has invested over $3.3 billion in Queensland, which is one of the biggest investments by an Indian company in Australia.
“We would not be investing our time, money and energy in this manner if our projects were not viable and if we were not serious about delivering our projects which will ultimately generate more than 10,000 direct & indirect jobs across all of our projects.
“The projects are viewed in a positive light by the Queensland Government and considered as critical infrastructure investments. The projects continue to retain the support of the Queensland Government.
“Adani Australia will now fully consider and adjust to the constraints the veto of NAIF funding brings. Adani Australia is 100 per cent committed to Queensland, we have a strong regional Queensland presence. This will not change.
In response to Ms Palaszczuk’s letter to Mr Turnbull, Northern Australia Minister Matt Canavan said the Queensland government had “chosen to stand in the way of North Queensland jobs as its first official act”.
“It was the Palaszczuk Government that first asked last year that the NAIF consider a loan to the Adani Galilee rail project in a letter from the now-sidelined former Treasurer Curtis Pitt,” Senator Canavan said.
“But what the Queensland Premier has failed to say today is whether she intends to block all investment in the Galilee Basin.
“The people of regional Queensland deserve to know which jobs will be next on Labor’s hit list.
“I hope the Adani project proceeds because there are 800 people whose current jobs depend on it, and thousands of future jobs hang in the balance. If Adani does proceed it will be in spite of Queensland Labor not because of it.”
Under the constitution, the federal government funding must be facilitated by the state government to the private company.
Ms Palaszczuk said newly appointed Treasurer Jackie Trad, the state’s Deputy Premier, would write to federal Northern Australia Minister Matt Canavan to provide the same advice.
Earlier today, Senator Canavan wrote to Ms Palaszczuk about the Adani veto.
“I note an investment decision has not yet been made on Adani’s NGBR proposal but is unlikely to progress any further in the NAIF’s assessment given your announced position (during the campaign),” Senator Canavan said.
“This project is crucial to opening up the Galilee Basin and would mean economic growth, and jobs for many Queenslanders. I would appreciate if you could confirm by written notice that your government will veto the provision of the NAIF finance to this important project. Further, I would appreciate your urgent advice on whether your government intends to veto any investment proposals to the NAIF that seek to service the Galilee Basin, or more broadly in Queensland.”
During the campaign, the Integrity Commissioner wrote to Ms Palaszczuk and said she should not make any decisions about any NAIF applications, because of a conflict of interest created by Ms Palaszczuk’s partner working on Adani’s NAIF application.
However, she flouted this advice and said she would veto the loan. Ms Palaszczuk has not said what she would do for other NAIF projects, such as Aurizon’s application to build a rail line in the Galilee Basin.

'Bastard Child': Review Of Controversial Emissions Fund Finds 'Significant Risk'

Fairfax - Peter Hannam

Some of the carbon offsets operating under a controversial $2.5 billion fund set up by the Abbott-Turnbull government are at "significant risk" from bushfires, according to a review by the Climate Change Authority.
The audit of the Emissions Reduction Fund, released by the authority on Monday, released by the authority on Monday, found that evidence of systemic problems had yet to emerge, but that there were questions over whether some of the carbon stored under the scheme would have been stored anyway.


World carbon emissions on the rise
A new report has shown world carbon emissions set to reach a record high this year, with a 2 percent rise according to scientists.

The report noted the fund had so far paid out $2.23 billion for 189 million tonnes of emissions reductions, or about $11.80 per tonne. Some 26 million tonnes had already been delivered.
"Overall, this review has found that the ERF is generally performing well," the report said. "It has successfully incentivised new domestic abatement at low cost that will help contribute to Australia meeting its international target commitments."
However, critics such as Clive Hamilton – an academic at Charles Sturt University who resigned from the authority's board in February –dismissed the review as giving "a veneer of legitimacy to a discredited scheme".
"The federal government has stopped talking about the ERF," he said. "It's like bastard child whose existence no one wants to acknowledge."
Tim Baxter, a researcher at Melbourne University's Australian-German Climate and Energy College, described the report as "a light touch" that failed to address the many systemic problems with the fund.
"Pretty much in every methodology you look at there's some fundamental accountability issue," Mr Baxter said. "This is almost big enough that 30, 40, 50 per cent of the abatement you're claiming under this methodology doesn't exist."

The report's release comes ahead of a review of the government's overall climate policies is scheduled to be released before the end of the year.
Josh Frydenberg, Minister for the Environment and Energy, welcomed the report's view that the ERF was "performing well".

"The government will carefully consider the review's recommendations and table its response in due course," he said.

Forest issues
Among the issues the report did highlight was the fact 139 million tonnes of the abatement paid for was in vegetation and soil, and at "significant risk" of reversal.
"[T]he Authority recommends that scheme participants submit plans to the Clean Energy Regulator (CER) outlining how they will maintain carbon in their projects and deal with the risk of fire," it said.
Of the vegetation projects, 75 per cent were located in the Cobar Peneplain and Mulga Lands of south-west Queensland and western NSW.
The current buffer of 5 per cent "may need to be reviewed to take into account increasing risk of natural disturbances, particularly if sequestration projects are geographically concentrated", it said, adding any changes should not affect existing projects to avoid creating investment uncertainty.
Mr Baxter also questioned the discounting by only 25 per cent projects that were earmarked to run for 25 years compared with those meant to store carbon for a century.
The discount rate seemed more to do government borrowing costs rather than natural processes.
"A 25-year permanence period is very, very different - and a lot more than a 20-25 per cent difference - to a 100-year permanence period in terms of emissions," Mr Baxter said.
"The odds of a government stepping in and purchasing that future abatement…if one project fails through from fire or drought …seem pretty slim."

Landfill issues
Similarly, he queried the report's findings that landfill projects had met the "additionality" conditions even when ample evidence existed –such as reported by Fairfax Media – that many such ventures would have happened without the ERF.
Almost all landfill operators had joined the bidding for funds even though they got money from the Renewable Energy Target, didn't have to comply with the newness requirement, and "a decent percentage are required by law in their home state" to deal with emissions, Mr Baxter said.
"You've got things like that which are really, really problematic," he said.
Another issue raised in the report was the market concentration. Just two firms – GreenCollar and Corporate Carbon – control 55 per cent of the abatement supplied by Carbon Service Providers.
The authority did not recommended any specific steps to address the domination of a few companies.
It did, however, call for the government to seek to amend the Carbon Credits Act 2011 so that agents be required to pass a fit and proper test to address concerns such as those raised by the National Farmers' Federation about CSPs "behaving unscrupulously".
By international standards, the ERF was "reasonably good" and had problems that could be fixed if governments were serious, Mr Baxter said.
"There are loopholes there you can drive a truck through but they can be closed over time," he said.

Political view
Adam Bandt, the Greens climate change spokesman, though, said the previous Labor/Greens program had resulted in "real emissions cuts with polluters paying the public $24 a tonne".
"Under the Liberals, pollution is rising and taxpayers are paying $12 per tonne for forest schemes that might go up in smoke," Mr Bandt said. "Real climate policy shouldn't be reversible.
"We can plant all the trees in the world but until we cut pollution from coal and petrol, we won't stop climate change and the bushfires it will bring," he said.

Defence Warns Of Climate Change Peril For Food, Energy And Peace

The Australian

The Defence ­Department has laid out what it sees as the national security consequences of human-induced ­climate change.
Man-made climate change could increase competition for food, resources and arable land, placing a greater burden on our defence forces who must respond to an ­increased risk of conflict.
In an official submission to a Senate inquiry, the Defence ­Department has laid out what it sees as the national security consequences of human-induced ­climate change, warning that dealing with the fallout from ­global warming could increase the burden on Australia’s military.
It paints an uncertain, yet bleak, picture: climate change intensifying natural disasters and the mass movement of people across the region. It features as a kind of wildcard that could tax the capabilities of soldiers and imperil Australia’s energy markets, upon which defence relies heavily.
Defence describes human-­induced climate change as a “threat multiplier’’ which will intersect with existing problems of population density, poor governance, poverty and ethnic rivalry for food, water and resources. It will also increase the frequency, and intensify the effects, of natural disasters, potentially obliging ­Defence to devote more of its resources to disaster relief among Australia’s neighbours.
“Many of the states in Australia’s region face some or all of these challenges, in addition to being vulnerable to climate change impacts such as temperature and sea level rise,’’ Defence says. “Unmitigated, climate change could exacerbate the potential for conflict and the consequence of any climate change-related threats could lead to an increase in the demand for a wide spectrum of Defence response.’’
It is “too early” to say precisely what resource pressures will be placed on Australia, but it warns “the current most likely forecast climate changes may require higher levels of commitment that may create concurrency pressure for Defence from as early as the middle of the next decade, or earlier if climate change related impacts on security threats accelerate”.
“Although the full range of impacts are not yet able to be determined, there is potential for climate change to exacerbate existing threats and future governments may increase demands on the ADF to impose new commitments. These impacts could include an ­increase in illegal, unreported, or unregulated fishing or irregular maritime arrivals to Australia.”
Citing conflicts in Syria and Africa, Defence argues climate change could exacerbate ethnic or other social grievances in Australia’s region, fostering terrorism or cross-border conflict.
“Climate change may also contribute to greater irregular migration pressure in vulnerable counties to Australia’s north, potentially becoming a substantial security threat for Australia.”
Defence says climate change “will exacerbate storms of increasing severity that will continue to impact national electricity infrastructure”.
“A more secure power system will be resilient to the integration of new technologies and resistant to the threat of natural disasters and cyber security attacks.”
It says the transition from fossil fuels to renewables is likely to ­“redefine national energy supply chains’’ and warns reliable energy generation is essential for the ­military.
“As an end user of energy ­sources Defence must ensure that it retains undisrupted access to ­appropriate sources of energy.”
It argues its training facilities could become less usable “due to work health and safety factors such as extreme heat” and notes that rising sea levels could make some defence facilities more expensive to maintain or “unviable to operate’’.

'Existential Threat': Climate Change Risks Finally Grab Australia's Attention

Fairfax - Peter Hannam

When Cyclone Evan slammed into Samoa five years ago next week, it triggered the near-complete loss of power and water supplies in the capital, Apia, and forced villagers to relocate to schools and the university for months.
The category-4 tempest was the strongest to hit the Pacific nation in a couple of decades. For Samoan Brianna Fruean, one of the Pacific Climate Warriors, it was another sign - along with rising sea levels, and more intense floods and droughts - that action needed to be taken.


Water bills headed 'same way as energy'
Rising population and climate change could translate into much higher water bills without action being taken now.

"Climate change is happening right in front of our eyes," Fruean said this week on the sidelines of a meeting in Fiji of Civicus, a global civil society group.
Helen Clark - the former New Zealand prime minister and an ex-senior United Nations official - was also at the Suva gathering. Clark says she is not surprised by its central topic.

"You can't come to a meeting in the Pacific and not have climate change as the focus," Clark tells Fairfax Media. "Everybody talks about it because it's an existential threat to the Pacific."
Samoa at least has high ground where people can seek refuge. Tuvalu, Kiribati and the Marshall Islands are nations barely three metres above sea level, making them particularly vulnerable to storm surges and rising seas.
Such vulnerabilities are not lost on Australian authorities.
Despite the often tortured debate stoked by some conservative politicians and commentators denying climate change is real, a range of agencies are quietly assessing abilities to cope with threats from a refugee influx, increased calls for aid, and impacts on the domestic economy.

And as 2017 draws towards a close, Environment and Energy Minister Josh Frydenberg is putting the final touches to a review of Australia's climate policies due for release by month's end.
Frydenberg offers no hint of any major surprise, repeating familiar lines that Australia's pledge to the Paris climate accord - to cut 2005 level emissions 26-28 per cent by 2030 - "is one of the largest reductions on a per capita basis and is a commitment we plan on honouring".

Scrutiny
While festive seasonal distractions may dim the chance of an immediate and close scrutiny of his climate review, the challenges for the Turnbull government will still be waiting when politicians reconvene in the new year.
International attention will also remain, whether at this week's One Planet Summit in France to assess the progress on the Paris climate deal two years on, or late in 2018, when all nations will be pressed to increase their ambition to curb the greenhouse gas emissions driving global warming.

On the emissions front, Frydenberg has already had his options significantly reduced.
The government's signature National Energy Guarantee aimed at providing a more reliable, affordable and sustainable electricity supply locks the power sector into the same 26-28 per cent pollution reduction that the whole economy is supposed to track.

Even if Frydenberg can convince the states to sign up - a huge ask unless there is a major power outage over the summer - such an approach won't be the best.
"Electricity production in OECD countries is always part of the cheapest options to decarbonise the economy, and it's also a big source of emissions," said Yann Robiou du Pont, a researcher at Melbourne University's Australian-German Climate & Energy College.
"There are fewer assets to transform and they're usually closer related to governmental decision-making."
In Australia's case, the electricity sector is the largest source of emissions, accounting for about a third of the total, and home to many ageing and relatively dirty coal-fired power plants.
Another big source, land clearing, is again on the increase in states such as Queensland and NSW.
"Energy efficiency and productivity will play an important role as we transition to a lower emissions future," Frydenberg said. "We already have in place the National Energy Productivity Plan for a 40 per cent improvement by 2030 and we are always looking at ways to improve in this area while delivering an affordable and reliable energy system."
Mr Robiou du Pont notes the Climate Change Authority's own recommendation that Australia's fair contribution to emission cuts would be much higher than the Abbott-Turnbull government's offer, given the country's high per capita pollution and also relative wealth - if not political will - to transform its economy.
The authority - which the Coalition government tried but failed to abolish - called for a 25 per cent cut of 2005-level emissions by 2020, and 54 per cent by 2030. That's roughly double the government's ambition.

'Not serious'
Mark Butler, Labor's climate spokesman, said his party is sticking with a 45 per cent emissions reduction goal that "is consistent with the Paris Accord goal of limiting global warming to below two degrees".
"It is clear that the government's approach of a pro rata allocation of abatement between sectors will ensure the costs of meeting any emission reduction target will be higher than they need to be," Butler said.
"The electricity sector has a lower cost of abatement than most other sectors in the form of renewable energy, and renewable energy is already the cheapest option to replace ageing coal-fired power stations that will inevitably retire," he said.
(Energy giant AGL is expected to announce details within days of what its plans are post-2022, when it closes the ailing Liddell coal-fired power station in the Hunter Valley.)
Sectors like manufacturing and livestock agriculture have a much larger cost of abatement and few ready-to-deploy abatement technologies.
"The government's insistence each sector meets targets based on a pro rata division of the national emission reduction target just confirms they do not take climate change seriously," Butler said.

Business shift
Companies, meanwhile, are beginning to look beyond the political cycle.
Sarah Barker, a special counsel for Minter Ellison Lawyers, said there had been "a noticeable shift in the approach of the business community to climate risk in the past 18 months".
"Historically, the issue was largely viewed as a singularly 'environmental', ethical, non-financial issue - perhaps relevant to corporate social responsibility, but nothing more," she said.
"Increasingly, Australian businesses are realising that climate change presents significant financial risks - and opportunities - and that they need to strategise around this issue in the same way as they would any other industry trend or economic risk factor."
"Business has far less tolerance for climate change denialism than it did even a few years ago," Barker added. "Their investors are concerned about it.  Their insurers are concerned about it.  Their customers are concerned about it."

'New denialism'
Submissions to recent and ongoing Senate inquiries also indicate that whichever parties take government at the next election, many agencies already  have preparations underway to adapt to climate change.
Peter Whish-Wilson - the Greens' spokesperson for Healthy Oceans who led a Senate inquiry into the impact of climate change on the marine environment that last week released its report - said policy delay was "the new form of climate denialism".
"Whether you stick your head under the water up on the Great Barrier Reef and see the devastation first-hand or you talk to the defence force personnel involved in planning for natural disasters in the Pacific, you know that the effects of global warming are upon us and that without action the future is looking grim," Whish-Wilson said.
"We now need to think about the increase of marine heatwaves as part of the range of climate impacts we need to prepare for, like we do with bushfires and droughts," he said.

'Threat-multiplier'
For its part, the Defence Department's report to a separate Senate inquiry into the implications of climate change for Australia's national security detailed how it expects the "threat-multiplier" effect will hinder its "warfighting role".
"The national security threats that may emerge include inter-group rivalries, water, food and resource shortages and irregular migration," it said. "Many of the states in Australia's region face some or all of these challenges, in addition to being vulnerable to climate change impacts such as temperature and sea level rise."
Defence noted how it deployed 1000 staff to help Fiji recover from its $2.5 billion hit from Cyclone Winston, a category-5 storm in 2016. The HMAS Canberra was part of the deployment, along with planes that delivered 520 tonnes of humanitarian aid.
In its submission, the Department of Immigration and Border Protection said "climate change effects could permanently alter normal business, including the accessibility of assets and capability".
Interestingly, it noted that "there is no internationally agreed position on expanding the current definition of a refugee or impetus to create a new international protection obligation to encompass people displaced by climate change".
Organisations such as the Kaldor Centre for International Refugee Law at the Univerity of NSW downplay the threat of a flood of refugees crossing borders because of climate change, saying in its submission to the Senate that "there is scant evidence" so far.
"Internal displacement may, however, generate low-level social tensions and potential conflict over key resources such as land, housing, food, water and employment, and increase the human insecurity of the poor," said Jane McAdam, the centre's director.

'Climate debt'
Such a view of local disruption dovetails with those of both Helen Clark and Brianna Fruean.
Clark said climate displacement is already affecting African subsistence farmers forced off their land by rainfall patterns that are becoming harder to predict: "If you plant and the rain doesn't come, you've blown your credit and you're poverty stricken."
"We don't want our people to move," Fruean said. "We want to put that as the very, very last resort."
That said, Pacific nations are watching with concern the Australian and Queensland governments' efforts to promote the huge Adani-owned Carmichael mine, which threatens to open up a massive new coal province.
"The execution of the Adani project will be a huge carbon bomb for us in the Pacific," Fruean said.
She dismissed the characterisation of funds from rich nations to help her people cope with worse weather extremes and rising sea levels.
"I see it as climate debt," she said. "We wouldn't need that aid if it weren't for these countries investing in fossil fuels, and really creating the damage that we're seeing in our islands today."

Great Barrier Reef Will Be Dead By 2100, Says David Attenborough's Blue Planet II

Fairfax - Latika Bourke

London: Coral reefs – including Australia's Great Barrier Reef – will be dead by 2100 due to human "maltreatment of the oceans", David Attenborough's Blue Planet II has declared.
Attenborough's follow-up documentary series, which took four years to film and produce, finished airing in Britain on Sunday night (local time). It ended with his grim warning about the state of our oceans, which Attenborough said were "under threat now as never before."


He said climate change, plastic pollution and over-fishing were all contributing to the demise of coral reefs.
Blue Planet II has been Britain's most-watched show of 2017, with 14 million tuning into the first episode of the wildlife series. Nine will air the seven-part series on free-to-air television in Australia in 2018.
A major section of the program is devoted to the Great Barrier Reef, where filming began in 2016 on Lizard Island.
The program charted the Great Barrier Reef's worst-ever bleaching event, caused by a combination of a warming ocean and an El Nino, which turned healthy corals into white rubble.
The following summer brought another big bleaching event, centred more to the south, leaving about half the reef affected during the two bouts.
Attenborough said more than two-thirds of the world's coral reefs had suffered from rises in ocean temperatures over the last three years.

"Coral reefs could be gone by the end of this century," Chris Langdon, professor of Marine Biology and Ecology at the University of Miami's Rosenstiel School of Marine and Atmospheric Science, told Attenborough.
"And the cause of this? Carbon dioxide. The more carbon dioxide in the atmosphere, the more acidic the ocean becomes," said Attenborough, raising the twin threat - acidification, along with warmer oceans - that is being triggered by changing the chemistry of the atmosphere.

"Evidence points to the burning of fossil fuels as the primary cause for these increasing levels of carbon dioxide.
"And this is man-made beyond question?" Attenborough asked Langdon.

"Beyond question," replied Langdon. But he said the death of the reefs could be averted by switching from fossil fuels to renewable energy sources like solar and wind.
The coalition, under both Malcolm Turnbull and his predecessor Tony Abbott, have launched ideological attacks on the former Labor government's marine parks plan and renewable energy target.

It has scaled back the 2020 renewable energy target and is preparing to reduce the area of Australia's marine parks by almost half. Some 1,200 scientists have called on the government to reconsider, saying the cuts to the parks are a "retrograde step."
Attenborough said the creation of more marine parks, which currently cover just one per cent of the ocean, were "vital" to protecting reefs from dying.
Yet despite the dire scenes depicted in his documentary, Attenborough remained hopeful.
"We can turn things around, we've done so once before," he said.
Attenborough cited the 1986 agreement to end commercial whaling, which he said had been instrumental in the recovery of whale species, despite some countries – such as Japan – continuing to hunt the creatures.

Plastic pollution entering dolphin tissue
Attenborough devoted much of the program to the eight million tonnes of plastic that ends up in the world's oceans annually.
The Blue Planet II team said they found plastic in every single ocean they filmed, "even in the most remote locations".
The program showed fish entangled in nets of plastic, a rice packet spewed up by an albatross in Georgia, and another bird killed by a plastic toothpick that had pierced its stomach.
"Once in the ocean plastics break down into tiny fragments – micro fragments," said Attenborough.
He said these, combined with the industrial chemicals that end up in the ocean, caused a "potentially toxic soup." Small organisms ingested the micro plastics and sent the toxins right through the oceanic food chain, he said.
"Dolphins are at the top of this food and it's now thought that pollutants may be building up in their tissues to such a degree that a mother's contaminated milk could kill her calf," he said.
He said scientific autopsies of dolphin calves found dead off the coast of the United States had been performed.
Attenborough said the problem "must be tackled for the sake of all life in the ocean."
The program also showed how clown fish make noises to protect themselves from predators. Clown fish which become separated from their families, as famously depicted in the Pixar blockbuster animation film Finding Nemo, can use noises to find their way back to their anemones.
But those noises can be drowned out by fishing boat engines roaring overhead.
"We're only now beginning to realise what an impact our noise is having on the ocean," said Attenborough.

Australia's response
Environment Minister Josh Frydenberg defended the coalition's record on the reef and said it was "rightly valued by the Australian and international community as a place of intrinsic beauty and incredible biodiversity."
But he did not address the coalition's plan to cut back the marine parks and the amount of renewable energy, instead attacking Labor's management of the reef when they were in power.
"After six years of Labor mismanagement, the Great Barrier Reef was on the World Heritage Committee's watch list to be 'in-danger,' with five massive dredge disposal projects in the marine park planned," he said.
"The Coalition took unprecedented action to fix Labor's mess ending all five dredge disposal plans as well as banning all future capital dredge disposal projects in the Great Barrier Reef Marine Park.
"We also developed a comprehensive Reef 2050 Long-Term Sustainability Plan setting out our strategy to manage, protect and improve the Reef for future generations."
"As a result of the Coalition's actions, the World Heritage Committee removed Australia from the 'in-danger' watch list, and praised Australia as a global role model for reef management.
"The Coalition has a comprehensive set of policies to invest in, and protect, the Reef having already invested $461 million in reef funding as part of a broader $2 billion ten-year plan by Australian governments focussed on water quality, reducing run off and eradicating crown-of-thorns starfish."
"Just this week we announced a world leading research project which will mix warmer surface water with cooler waters from the deep in an effort to reduce the impacts of thermal stress on the Great Barrier Reef to mitigate coral bleaching events.
"This is on the back of announcement last week of a trial on the Great Barrier to identify highly resilient reefs and pilot 're-seeding' to restore coral."

British considering plastic tax
Like millions of Britons, the British Environment Secretary Michael Gove is a fan of the series.
Gove said he was "haunted" by episode four called Big Blue. He vowed the Conservative government would "work urgently to identify further action."
"The imperative to do more to tackle plastic in our oceans is clear," he said. "We must act."
The British government said in its budget statement that it would explore ways to use the tax system to curb the use of single-use plastics like takeaway containers.
"The UK led the world on climate change agreements and is a pioneer in protecting marine environments," Chancellor Philip Hammond said. "Now I want us to become a world leader in tackling the scourge of plastic, littering our planet and our oceans."
The government has already introduced a 5p (9c) charge for all plastic bags in the UK.
Government data shows Britain's seven main retailers have issued 83 per cent – or 6 billion – fewer bags in 2016-17 compared to 2014, prior to the charge.

Koch-Backed Business Group Splinters in Climate-Change Dispute

A business-backed group that rose to prominence by prodding state legislatures to cut taxes, environmental regulations and gun restrictions, now finds itself at a crossroads amid declining membership and a bitter dispute over climate change.
The battle at the American Legislative Exchange Council erupted at the group’s winter meeting in Nashville, Tennessee, this week as members scrapped a measure declaring that climate change is not a risk after opposition from Exxon Mobil Corp. and Chevron Corp.
"It was corporate blackmail," said Steve Milloy, a policy adviser for the Heartland Institute, a group critical of climate science. "They basically said, ‘We’re going to leave.’ "
The dispute over the climate provisions highlights the internal discord for the Arlington, Virginia-based group, which gained fame fighting President Barack Obama’s regulatory agenda. Over the past five years, more than 100 businesses left the organization, illustrating corporate concerns that the group may be going too far.
ALEC, which has been funded by companies like Koch Industries Inc. and coal giant Peabody Energy Corp., has 2,000 mostly Republican state legislator members, which it pairs with representatives from corporations and free-market interest groups. In recent years it debated model measures for state legislatures that take aim at state renewable energy requirements, set stricter voter identification requirements and would have U.S. senators appointed by state legislatures, not elected.

But those debates have been contentious, and turned the group into a bogeyman for consumer and environmental groups concerned about how corporate priorities can be pushed into the agenda of states nationwide. And that pressure has led to some internal woes.
Over the past five years ALEC has shed more than 100 members including Ford Motor Co. and Expedia Inc., largely over its position against climate rules, renewable energy and other issues that don’t jive with corporations’ publicly stated sustainability goals.
"Companies will come and go, and we’ve added companies too," Jason Saine, a North Carolina House member who is ALEC’s incoming chairman, said in an interview. "We’re healthy and the organization is growing. ALEC has matured over the years and learned how to have these discussions in a mature way, so we can talk about them."
Despite the high-profile company departures, ALEC says that it has about 300 corporations and other private members, such as trade groups and lobbyists, that are part of the group. It’s overall revenues have increased in recent years, from $8.4 million in 2012 to $8.9 million in 2015, the most recent year available, according to its tax returns.
Nick Surgey, director of Documented, a watchdog group that investigates the link between corporations and public policy, says the corporate defections have led to free-market activist groups with harder-edged views moving in to fill the void at ALEC.
"That vacuum is being filled by a radical agenda and these really extreme ideas are coming to the forefront," Surgey said.
As 1,000 attendees munched on beef short ribs and deviled eggs with okra at the Omni Hotel Nashville, a top topic of discussion was the climate measure, meant to encourage states to prod the Environmental Protection Agency to rescind its determination under Obama that climate change is a risk to human health and welfare and therefore requires regulation.
Exxon, Chevron and Honeywell International Inc. objected, telling the group it would lead to protracted litigation and create business uncertainty.

Indiana State Representative Dave Frizzell, a former national chairman of ALEC, said he told those assembled in the closed-door session that if the measure was approved it would result in a corporate exodus similar to what occurred after the group was linked to "stand your ground" gun legislation following the shooting of the unarmed black teenager Trayvon Martin in Florida in 2012. A score of companies, including McDonald’s Corp., The Coca-Cola Co. and Kraft Foods Group Inc., cut ties with the organization after that.
Since then ALEC has tried to "narrow our focus to main issues and policy," Frizzell said after joining the ballroom in prayer before a breakfast of scrambled eggs and biscuits. "We felt that’s something we don’t need to be dealing with."
The climate measure was backed by the Heartland Institute, an Illinois-based global warming skepticism group that has linked global warming to the beliefs of unabomber Ted Kaczynski, as well as groups like the Competitive Enterprise Institute and the right-wing advocacy organization the James Madison Institute.

Lose Funding
"ALEC’s primary allegiance, and the allegiance of its public sector members, must be to consumers and not to the producers of particular goods and services," they wrote in a letter to members of ALEC’s Energy, Environment, and Agriculture Task Force.
Myron Ebell, a director for the Competitive Enterprise Institute and long-time critic of climate science, said he canceled his flight to the meeting after he got word the endangerment resolution had been withdrawn.
"I believe that an overwhelming number of the legislative members of the task force were going to vote for it during the full task force meeting, but ALEC got some board members to show up and say this is divisive and we will lose funding," he said in a phone interview from Washington. "Losing funding is a rather sensitive issue at ALEC."

Internal Debate
In addition to model legislation mirroring Trump’s executive order requiring two regulations be repealed for every new one, ALEC also is considering a resolution recommending that Congress repeal the 17th amendment, adopted over 100 years ago to allow citizens to directly elect their U.S. senators instead of state legislators.
"The 17th Amendment has had many unintended consequences including runaway federal deficits, unfunded mandates, overreach by federal agencies and excessive and burdensome impositions by the federal government upon the States," the model bill states.
ALEC declined to identify which member was backing the resolution.
"It’s a new radically reactionary proposal that came up in this new period of Trump-dom," said Lisa Graves, a former Justice Department attorney who launched the Center for Media and Democracy’s "ALEC Exposed" program in 2011. "This certainly seems to be evidence of them feeling emboldened to embrace an extreme counter-democratic measure."
In the internal debate over the climate measure, a representative for Pfizer Inc. stood up and said the pharmaceutical company was based on science, and United Parcel Service Inc.’s representative weighed in, saying global warming was real, Milloy said. Ken Freeman, Exxon’s U.S. government relations manager simply said, "I am opposed to this," and walked away, Milloy said.
"UPS, and many others, made it clear that we do not support the resolution and that it conflicted with our corporate vision of responsible environmental actions," Kara Ross, a company spokeswoman, said in an email. "We worked to defeat the proposal and demonstrated how expressing corporate members’ views were key in leading to the withdraw of the resolution."
"What’s so interesting to me about this endangerment vote particularly is that its so reflective of this bigger conflict," said David Pomerantz, executive director of the Energy and Policy Institute. "You have these ideologues, these Heartland Institute types who aren’t really marching to the beat of the same drum, who are really zealots."
"My feeling is this is being driven by the fact they need to stay relevant in the Trump era," he said.
