Key Points
  • A pair of activists say they were inspired to write a book aimed at kids after hearing the Prime Minister read out children's letters
  • They were "thrilled" to receive the support of Sir David Attenborough, who sent them a handwritten letter
  • The book includes a postcard calling for climate change action that young people can send to the PM
Two Sunshine Coast environmentalists are calling on the Prime Minister to take immediate action on climate change and they're being backed by none other than Sir David Attenborough.

Helen Moffitt and Jim Bird have self-funded 10,000 copies of an activity book that comes with a postcard for children to sign and send to Scott Morrison.

Ms Moffitt said the $6,000 initiative would be worth every cent if the book inspired and empowered the next generation.

"The reason we've aimed this towards the children is because they're tomorrow's generation — they're going to be left with what today's generation leaves them," Ms Moffitt said.

"Kids need a voice [and] those who are not old enough to vote yet will have a voice.

"They're given a voice through the postcard."Mr Bird said hearing Prime Minister Scott Morrison read letters sent to him by children inspired the 16-page book, which took one year to complete.

"We'd like to really make it an Australia-wide [initiative], because the only way it's really going to succeed if the Prime Minister realises that people know that he's receiving these postcards," Mr Bird said.

He said 3,000 postcards had been distributed but he had no way of monitoring how many were sent to Mr Morrison.

'Thank you very much'

Mr Bird said he could hardly believe it when he and Ms Moffitt received a warm, handwritten letter of encouragement from Sir David Attenborough.

"It was unbelievable, the way it came … we hadn't really given our address," Mr Bird said.

"It was actually sent to SCEC – the Sunshine Coast Environment Council – so he must have looked on the website, got the address and sent it to them. 
"We were we were absolutely thrilled."
Sir David's note kept Mr Bird motivated, he said, and helped keep self-doubt at bay. (Supplied: James Bird) 

Mr Bird said receiving the response within a few weeks lent credibility to the cause and kept him motivated.

"Sometimes you say 'What on Earth are we doing? We're not going to get anywhere,'" he said.

"But it brings us back into thinking up original ideas [and] we'll do what we can, as best we can."

The book took Mr Bird and Ms Moffitt about a year to finish. (ABC Sunshine Coast: Meg Bolton)

Call for action

Mr Bird said the planet would be detrimentally affected if the government continued to focus on climate targets instead of taking immediate action.

"We haven't got 30 years," he said.

"We should be stopping deforestation [and we] should be planting right now."

He called on the government to address climate change with the same interest and enthusiasm as it approached the pandemic.

"We're addressing it, we're busting a gut actually to try to solve it, we don't care how much it costs and how much it inconveniences us," Mr Bird said.
"Wars and pandemics will come and they will go, but climate change is here, is progressing and it's here to stay."
The Prime Minister's office has been contacted for comment.

Suffering through seasons

In the meantime, Sunshine Coast wildlife veterinarian Ludovica Valenza said more animals were dying this year because of the change in seasons and natural disasters.

"Wildlife are trying to adapt to these changes, and for that reason we're getting them in for all sorts of different causes" she said.

"It's very bizarre, because even for this time of the year we're seeing baby birds and baby possums and macropods – so kangaroos and joeys that we wouldn't be seeing at this time of the year – coming in."

Data from the Australia Zoo Wildlife Hospital showed 50 per cent more animals were admitted in March 2021 than in March 2018.


Dr Valenza said trauma season usually ran from September to February, but more animals were dying because they were remaining active outside regular times.

The Australia Zoo Wildlife Hospital team recently treated its 10,000 koala.

"I think it is just from the fact that we've had these extreme weather conditions out there," she said.
"This is due to their habitat being reduced."
'Dear Prime Minister'

(AU RenewEconomy) New Australian Climate Service To Coordinate Responses To Climate Disasters

RenewEconomy


The Morrison government will establish a new Australian Climate Service to coordinate and oversee preparation and responses to climate change, bringing together the work of key government agencies.

The Australian Climate Service will receive $209 million in funding in the federal budget to be delivered next week.

The new service will bring together expertise across a range of Commonwealth agencies, including the Bureau of Meteorology, Geoscience Australia, the Australian Bureau of Statistics, and the CSIRO.

The role of the Australian Climate Service will be to guide responses to emergencies triggered by extreme weather events, such as floods, storms and bush fires and will work in cooperation with Emergency Management Australia and the Government’s new National Recovery and Resilience Agency.

“This new capability will enable enhanced decision making for Emergency Management Australia and the new National Recovery and Resilience Agency,” Geoscience Australia CEO Dr James Johnson said.

‘The Australian Climate Service will generate new information and insights that are required to understand future climate and natural hazard threats and ensure better decisions are being made on things like how to build and where.”

“Through this ground-breaking partnership we will work with Emergency Management Australia and the new National Recovery and Resilience Agency to provide data and intelligence to support each phase of the emergency management continuum; Prevention, Preparedness, Response and Recovery.”

The Morrison government has faced increased pressure to respond to the growing impacts of climate change, particularly following a damaging and deadly 2019-20 summer that saw bush fires of unprecedented scale burn across much of Australia’s east coast.

The bushfires exposed gaps in the coordination of responses to the bushfire event, with state and commonwealth government agencies at times being slow to respond to the unfolding disaster.

Climate science research has stressed the increased likelihood of similar events happening in the future, as global warming amplifies the extreme nature of weather events and the increased regularity with which they can be expected to occur.

“We know just how devastating natural hazard events have been for communities all around the country over recent years. From the Black Summer bushfires and large-scale smoke events to devastating tropical cyclones and floods,” Bureau of Meteorology CEO Dr Andrew Johnson said. “We also know that with our changing climate, these events are likely to become more intense and impactful in future.”

“The new Australian Climate Service will help Australians better prepare for natural disasters well before they occur, by not just looking days ahead but years and decades. It will also enhance the Australian Government’s response during times of extreme weather, letting the community know much earlier what is coming, what’s in its way, how it will be affected and the consequences of that for the businesses and households.”

While the Morrison government has come under growing pressure to adopt more ambitious targets for reducing Australia’s emissions, it is understood that within some parts of the federal government that the growing threat posed by climate change fuelled impacts is becoming a growing concern – particularly when it comes to national security.

Chief executive of the CSIRO, Dr Larry Marshall, said that there was a challenge assessing the large volumes of data being collected about the Australian environment and translating it into meaningful recommendations for action to mitigate the impacts of extreme weather events.

“We have a deluge of data, but by turning it into insights, this will lead to tangible actions that benefit Australia. By quantifying the real risks for our people, industries, infrastructure, and supply chains, we can get ahead of what is coming next and be ready to meet it head on,” Marshall said.

“It will enable us to prepare better, to support communities across the country, and get back to business faster. Solutions from science will build the resilience of Australia’s economy to natural hazards in the future.”

The Australian Climate Service is expected to start operations at the beginning of July and will provide advice on all stages of emergency responses, including preparation, immediate responses during and after and event.

(AU SMH) It Stores Pollution 30 Times Faster Than Forest. What Is Blue Carbon?

Sydney Morning HeraldEmma Young

Shy dugongs, sea turtles and ancient, rocky microbes are all found among our seagrasses and mangroves. But why are politicians interested in these ocean meadows now?

At Australia’s westernmost point lies the Coral Coast, a land of strange extremities. Marine megafauna is more accessible than ever before. Tourists swim with humpbacks and manta rays and whale sharks. They hand-feed playful dolphins that obligingly stick out scarred and blemished dorsal fins scientists can use to identify them as individuals, name them and track their social behaviours.

But nearby, the dugong’s nose breaks the water only to breathe, and then it sinks back down, out of sight.

The sight of dugongs and their cousins, the manatees, once led sailors to believe they had seen mermaids, hence the name of the order they belong to: sirenia. But although they are legendary, they are shy and cryptic creatures.

Despite their imposing size, they don’t emit growls or rumbles but chirp and squeak like tiny birds. They are slow to escape the paths of boats and liable to get injured. Rather than play, they prefer to lumber along the seafloor alone or in small groups in a finicky search for a favourite type of seagrass that’s made harder by the fact they have terrible eyesight. They are perhaps at their most animated when they find the grass and use their teeth to rip it out, roots and all.

It is perhaps unsurprising that such a ponderous, vulnerable animal is globally declining, threatened with extinction.

Yet their ill-suitedness to this modern world has an exception. Western Australia’s Shark Bay, on the Coral Coast stretching from Cervantes to Ningaloo, is the dugongs’ stronghold, home to the largest stable population in the world.

In this World Heritage Site, where red desert meets ocean, numerous other endangered species, and all-but-extinct scientific curiosities, find refuge. Of the world’s 50 marine World Heritage Sites, Shark Bay is one of only four that meets every natural criterion for listing.

And Shark Bay, Ningaloo and its neighbour Exmouth Gulf, along with the Great Barrier Reef, are shaping up as some of the world’s most significant hotspots for blue carbon, one of the buzzwords on which Australia’s Prime Minister has pinned hopes for a climate change response.

What is blue carbon?

It’s now common knowledge that trees store carbon that would otherwise pollute our atmosphere.

This is why the sight of trees going up in smoke during bushfires is increasingly alarming to Australians, beyond the loss of homes and habitats the sight represents.

What is less well known is that three types of marine vegetation found where land and sea meet – seagrass beds in shallow waters, mangrove forests in between, and tidal (salt) marshes covered in saltbush – absorb and store carbon 30 times faster than forest.

As with trees, their roots and leaves store carbon, but the difference is the marine systems store most of the carbon in their soil (between 98 and 99 per cent for tidal marsh and seagrass, 60 per cent for mangroves).

And unlike with land forests, that soil is constantly building. It accumulates particles from the ocean, and sediment from run-off after storms on land.

Seagrass also provides a home for countless shell-dwellers such as clams and snails, and when these die and decompose they form carbonate sands that further build the soils.

These processes also work to furnish beaches and elevate the shoreline and seafloor, and thus not only store carbon but physically counteract sea-level rise, says Oscar Serrano, a post-doctoral research fellow at Edith Cowan University and one of Australia’s most eminent blue carbon experts.

Serrano was one of the lead authors of a report published in 2021 by UNESCO, which for the first time assessed the vegetation fields in its 50 marine World Heritage Sites. Significant hotspots included America’s Everglades National Park in Florida, the West Norwegian fjords and France’s lagoons of New Caledonia, but none were as impressive or diverse as Australia’s.

More than half the extent of the blue carbon ecosystems were in Ningaloo, Shark Bay, and the Great Barrier Reef alone.

All three contain all three types of ecosystems. Shark Bay and Ningaloo has significant extents of all three but particularly seagrass, and Shark Bay has the world’s biggest seagrass meadow. The Great Barrier Reef has vast swaths of all types.

The report also quantifies the carbon locked away in these fields and shows they contain 40 per cent of the total blue carbon held in World Heritage marine areas.

Other blue carbon hotspots in Australia, Serrano says, are the mangrove forests of the Carpentaria and Exmouth gulfs; the seagrass meadows of Spencer and Vincent gulfs of South Australia; and the mangroves and tidal marshes of the whole tropical and subtropical region, encompassing Western Australia’s north-east, the Northern Territory and Queensland.

Together, Australian blue carbon ecosystems sequester 20 million tonnes of carbon dioxide a year. That’s like taking 4 million cars off the road.

But globally, this blue carbon is being lost faster than tropical rainforests. Damage from coastal and marine development, severe weather and the effects of climate change is causing 3 million tonnes of blue carbon to be released back to the atmosphere each year.

An extreme example was a 2011 seagrass die-off in Shark Bay caused by a marine heatwave, releasing up to 9 million tonnes of carbon dioxide and causing “black water” in the region’s famous tourist destination Monkey Mia.

Another was the 2016 dieback deaths of about 7400 hectares of mangrove forest in the Carpentaria Gulf, attributed to a combination of extreme temperatures, drought and lowered sea levels.

An environmental solution or a political one?

In April, Prime Minister Scott Morrison called Australia’s oceans “part of the lifeblood of our economy” as he announced $100 million for ocean health including a $30 million blue carbon fund.

The promise, made as Morrison addressed 40 world leaders at US President Joe Biden’s climate summit, reflects how blue carbon is being entered into the country’s climate action political phrasebook.

As international pressure grows for Australia to set ambitious emissions reduction goals as major trading partners the European Union, UK, US and Japan have done, the federal government has resisted but is instead promoting its “practical” measures.

Green carbon is already part of the machinery of carbon offsets and credits used to counteract pollution so that Australia can reduce emissions.

The Australian government has a dedicated Emissions Reduction Fund to pay companies carbon credits to offset their pollution through planting trees.

It’s now working on an accounting method so polluters can claim credits through protecting or restoring blue carbon ecosystems.

Serrano, who is advising the government on how blue carbon projects can be banked against emissions reduction targets, says that in future any big polluter will need to invest in blue and green offsets to reach stated carbon abatement goals.

Three World Heritage sites hold 40% of the world's blue carbon  


He says the capacity of blue carbon per square metre is vastly greater than green. “Soils underneath the forest also have carbon but once the forest is mature the soil can’t accumulate more,” he says. “Most of the carbon is in ... the trees themselves. And they don’t live forever. They live 50, 100 years.

“If you lock away carbon you want it to be locked away for centuries.”

Projects are contemplated only for tidal marsh and mangrove forest. Seagrass is harder to account for as it can’t be mapped with aerial imagery, requiring boats and human labour, which are expensive.

But Australia is one of the first countries in world to get even this far.

“My feeling is the Australian government is wanting to take the lead worldwide on this, and they are starting with this, but soon other methods will follow and hopefully they will include seagrass,” Serrano says.

Part of the motivation could be that blue carbon may be an effective diplomatic tool for Australia, whose stance has recently been the target of angry calls for climate action from Pacific leaders; the government’s $30 million for blue carbon includes $10 million to support three restoration projects in developing countries, most likely in the Pacific.

Some Australian states are taking action of their own. Queensland is investing in blue carbon through its Land Restoration Fund, South Australia is developing a blue carbon strategy. In WA, climate action advocacy organisation Clean State has submitted to the government a $12 million blue carbon plan it says would create 270 jobs.

Can blue carbon help us meet emissions reduction targets?

Conserving, protecting and rehabilitating marine habitats is a worthy thing in itself, and blue carbon an interesting and legitimate scientific field, says Monash University biogeochemist Perran Cook.

Unquestionably, destruction of land and marine vegetation releases carbon dioxide and further imbalances the climate budget.

But the professor does not view blue carbon – or green – as a realistic way to combat fossil fuel emissions.

“When it’s used politically in such an important policy area, it’s hanging a hat on something very uncertain,” he says.

The first question is, can blue carbon restoration and protection balance our carbon budget?

The 20 million tonnes of carbon dioxide Australian blue carbon systems lock away each year is equivalent to less than 6 per cent of the emissions from fossil-fuel burning.

Australia’s 10 biggest polluters, all fossil fuel companies, together emit more than 150 million tonnes a year.

“The amount of CO2 we are emitting, the rate at which you’d have to rehabilitate [marine] areas would be enormous,” Professor Cook says.

The second question is, is it practical?

Space mirrors, fake volcanoes: the radical plans to fix the climate
Cook says that as with any marine engineering, restoration of blue carbon ecosystems is relatively expensive.

And land or sea, not all offsets are created equal.

Forests might be a high-quality permanent offset in one area, such as around Cairns with its high rainfall, but not in eastern Australia where climate change might one day turn them into savanna.

And he suspects a back-of-the-envelope calculation might show Australia would “really struggle” to repurpose enough agricultural land for tree planting on the scale required.

“We have turned a lot of forest into agricultural land,” he says. “We have burned a huge amount of fossil fuels. By replanting it all … you can’t offset a lot of the burning of fuels, just the carbon released from cutting down those trees in the first place.”

The third issue is stability.

Cook questions the idea of blue carbon having a longer lifespan in times when climate change, marine heatwaves and rising sea levels are destabilising oceans.

He mentions the devastation marine heatwaves caused in the Gulf of Carpentaria mangrove forests in 2016 and Shark Bay seagrass meadows in 2011.

“You’d have to be able to say it has a long term permanency to the atmosphere on a timescale of up to hundreds of thousands of years,” he says.

“The permanency of carbon in those supposed offsets is far from guaranteed.”

Serrano agrees Australia cannot rely on blue carbon alone.

“Even if we restore all blue carbon ecosystems in Australia these would only contribute a small portion of the necessary abatement,” he says. “Blue carbon needs to be part of the solution. But the solution is cutting emissions.”

What else is at stake?

Dugongs are not the only unique life forms along the Coral Coast that climate change places at risk. Numerous other endangered species rely on seagrass, such as green turtles. Dependent on the turtles are the tiger sharks that give Shark Bay its name.

Also in Shark Bay is the world’s only significant assembly of live stromatolites – reefs of rock and microbe domes, once the planet’s dominant life form, before the creation of oxygen rendered them extinct virtually everywhere but this sheltered, shallow and hyper-saline site.

NASA has studied them as part of a search for life on other planets, and like the water surface that hides the 10,000 dugongs cruising beneath, the single tourist boardwalk gives little perspective on the stromatolite reefs’ 135-kilometre expanse, on which only the odd researcher is permitted.

In Shark Bay another anachronism survives: a tiny cultivated pod of dolphins visiting the beach reliably and daily to interact with humans, achieving world fame among tourists and scientists.

At the other end of the Coral Coast, 400 kilometres north, Exmouth Gulf beside Ningaloo Reef is the only known site worldwide where green sawfish give birth to pups. A five-metre-long shark-like creature whose toothed snout, as long as its body, resembles a chainsaw blade, it looks fearsome but is one of the planet’s most endangered species.

Unseen along this stretch of coast are “stygofauna” found nowhere else but WA, the blind cave eel and blind gudgeon fish living deep underground in a complex terrain of limestone caves, rivers and lakes.

The peninsula on which Exmouth sits has fossilised coral reefs that date back to the last Ice Age, and whose very form has contributed to this staggering biodiversity by sheltering the Gulf from the rest of the ocean for millennia.

And this is just what is already known. The only region-wide survey of Exmouth Gulf in recent years found science had barely scratched the surface when it comes to the multitude of species living there, but it also found that despite this the Gulf would probably already qualify for World Heritage status.

Sea-level rise, marine heatwaves and cyclones threaten all the curiosities found in these blue carbon hotspots and those across Australia.

‘Black water’: The three Australian sites that are ground zero for climate change

Meanwhile, happily oblivious in Moreton Bay, Queensland, one of Australia’s smaller populations of dugongs is even more idiosyncratic than its western counterparts.

These dugongs form vast herds to raze their preferred seagrass variety annually, encouraging regular new, tender and delicious growth. The process is so uncannily like farming that experts call it “cultivation” grazing. Yet the dugongs cause no harm.

Unless we too can find a positive way to work with nature, the interconnectedness of all these systems suggests humanity stands to lose more than just safety and comfort to climate change; we stand to lose wonder, too.

Saving and preserving blue carbon ecosystems might not be the complete answer. But it could be a start.
