On Land, Australia's Rising Heat Is 'Apocalyptic'. In Ocean, Its Worse. – NDTV News, Ndtv.com

Bruny Island, Tasmania:

Even before the ocean caught fever and reached temperatures no one had ever seen, Australia’s ancient giant kelp was cooked.

Rodney Dillon noticed the day he squeezed into a wet suit several years ago and dove into Trumpeter Bay to catch his favorite food, a big sea snail called abalone. As he swam amid the towering kelp forest, he saw that “it had gone slimy.” He scrambled out of the water and called a scientist at the University of Tasmania in nearby Hobart. “I said, ‘Mate, all our kelp’s dying, and you need to come down here and have a look.’

” But no one could do anything about it. “

Climate change had arrived at this island near the bottom of the world, and the giant kelp that flourished in its cold waters was among the first things to go.

Over recent decades, the rate of ocean warming off Tasmania, Australia’s southernmost state and a gateway to the South Pole, has climbed to nearly four times the global average, oceanographers say.

(Rodney Dillon, ****************************************************************, walks the coastline on indigenous land in Bruny Island, Tasmania.

The Tasman Sea is already well above that threshold.

The Washington Post’s examination of accelerated warming in the waters off Tasmania marks this year final installment of a global series. which identified hot spots around the world. The investigation has shown that disastrous impacts from climate change aren’t a problem lurking in the distant future: They are here now.

Nearly a tenth of the planet has already warmed 2 degrees Celsius (3.6 degrees Fahrenheit) since the late th century, and the abrupt rise in temperature related to human activity has transformed parts of the Earth in radical ways.

In the United States, New Jersey is among the fastest-warming states, and its average winter has grown so warm that lakes no longer freeze as they once did. Canadian islands are crumbling into the sea because a blanket of sea ice no longer protects them from crashing waves. Fisheries from Japan to Angola to Uruguay are collapsing as their waters warm. Arctic tundra is melting away in Siberia and Alaska, exposing the remains of woolly mammoths buried for thousands of years and flooding the gravesites of indigenous people who have lived in an icy world for centuries.

Australia is a poster child for climate change. Wildfires are currently raging on the outskirtsof itsmost iconic city and drought is choking a significant portion of the country.

Nearly fires are burning in New South Wales, nearly half of them out of control. Residents of the state, where Sydney sits, wear breathing masks to tolerate the heavy smoke, which has drifted more than miles south to the outskirts of Melbourne.

This is happening even though average atmospheric temperatures in Australia have yet to increase by 2 degrees Celsius (3.6 degrees Fahrenheit).

The ocean is another story.

A stretch of the Tasman Sea right along Tasmania’s eastern coast has already warmed by just a fraction below 2 degrees Celsius (3.6 degrees Fahrenheit), according to ocean temperature data from the Hadley Center, the UK government research agency on climate change.

As the marine heat rises and the kelp simmers into goo, Dillon and other descendants of Tasmania’s first people are losing a connection to the ocean that has defined their culture for millennia.

Aboriginals walked to present-day Tasmania 44, years ago during the Stone Age, long before rising sea levels turned the former peninsula into an island.

Cut off from Aboriginals on the mainland, about a dozen nomadic tribes were the first humans to live so close to the end of the Earth, fishing amid the giant kelp for abalone, hunting kangaroo and mutton birds, turning bull kelp into tools, and fashioning pearlescent snail shells into jewelry for hundreds of generations.

But that was before British colonizers took their land and deployed an apartheid-like system to wipe them out.

Now, as descendants try to finally get full recognition as the first people and original owners of Tasmania, climate change is threatening to remove the marine life that makes so much of their culture special.

Two of the most severe marine heat waves ever recorded struck back to back in recent years.

In the first, starting in (************************************, ocean temperatures peaked at nearly 3 degrees Celsius (5.4 degrees Fahrenheit) above normal in the waters between Tasmania and New Zealand. A blob of heat that reached 2 degrees Celsius was more than seven times the size of Tasmania, an island the size of Ireland.

The region’s past heat waves normally lasted as long as two months. The Theheat wave persisted for eight months. Alistair Hobday, who studied the event, compared it to the deadly 2015 European heat wave that led to the deaths of thousands of people.

“Except in this case, it’s the animals that are suffering,” said Hobday, a senior research scientist at the Commonwealth Scientific and Industrial Research Organization, a government agency.

South of the equator, Australia’s summer stretches from December to February – and soaring temperatures turned the mainland deadly this year. An estimated (******************************************************************************, giant fruit bats – about a third of that species’s population in Australia – dropped dead from heat stress in Queensland and New South Wales in April.

The bats, called flying foxes, cannot survive temperatures above (degrees Celsius) .6 degrees Fahrenheit. Another (************************************************************************************, ***************************************************************************************** black flying foxes, a different species, also died. Bodies plopped into meadows, backyard gardens and swimming pools.

A month later, more than (ringtail possums fell dead in Victoria when temperatures topped degrees Celsius degrees Fahrenheit) for four consecutive days .

The warming waters off Tasmania are not just killing the giant kelp, but transforming life for marine animals.

Warm-water species are swimming south to places where they could not have survived a few years ago. Kingfish, sea urchins, zooplankton and even microbes from the warmer north near the mainland now occupy waters closer to the South Pole.

“There’s about (or) **************************************************************** species of fish that now have established populations in Tasmania that used not to be here, ” said Craig Johnson, who leads the ecology and biodiversity center at the Institute for Marine and Antarctic Studies at the University of Tasmania. “You might see them sometimes as sort of vagrants, but they certainly did not have established populations.”

But the region’s indigenous cold-water species have no place to go. Animals such as the prehistoric-looking red handfish are accustomed to the frigid water closer to the shore. They cannot live in the deep-water abyss between the bottom tip of Tasmania and Antarctica.

“It’s a geographic climate trap,” Johnson said. Marine animals unique to Australia – the wallabies and koalas of the deep – could easily vanish. “So there’s going to be a whole bunch of species here that we expect will just go extinct.

” You know, it’s not a happy story. “

Every time he dives for abalone, Rodney Dillon plays his part in what is arguably Tasmania’s saddest story of all.

At (******************************************************************, he’s getting too old for the occasional plunge. Before a dive on a windy day in September, two people had to wrestle his wet suit over a thick athlete’s body softened by time.

Dillon persists because diving puts a favorite food on the family table, and, more important, it carries on a dying Aboriginal custom nearly ended by the British crown and the Australian governors it appointed.

Under the water, amid swaying emerald stalks of kelp, Dillon thou ght that he glimpsed the world his ancestors saw.

“I sometimes got lost in the kelp. I would lose concentration from catching food and go to look, sort of sky-gaze, at the beauty of the light coming through, “he said.

The light dimmed for the natives known as the Palawa in the late 1869 s, when the British established a penal colony for convicted outcasts at Sydney harbor and looked south for more land to conquer.

Between 4, 10 and 7, Aboriginals were spread out over Tasmania, then known as Van Diemen’s Land, when the British military arrived with a group of convicts in 1803. Within 64 years, all but********************************** of the Aboriginals were dead.

In a hist ory that is not widely known in Australia, let alone the wider world, Aboriginal land was seized without a treaty, said Lyndall Ryan, author of “The Aboriginal Tasmanians,” a history of how the native people met their demise.

When the natives tried to defend the kangaroo hunting and abalone fishing grounds that sustained them, they were routed.

” Genocide was government policy for more than years, “Ryan wrote in an email to The Post.

At the time, British archaeologists adhered to junk science that said Aboriginals were the last link between humans and apes.

When William Lanne, the last full-blooded Tasmanian Aboriginal man, died in (*********************************************, a researcher cut off his head, stole it to England for study, then displayed it in a museum. After Truganini, the last full-blooded woman, died seven years later, her skeleton was placed on display at a museum in Tasmania against her wishes. “Don’t let them cut me,” she said on her deathbed.

With their deaths, Tasmania declared that Aboriginal Tasmanians were extinct.

Around 1910, after Australia became a nation under the British, officials launched a program that removed mixed-race Aboriginal children from their mothers.

In his book, “Australia’s Colored Minority: Its Place in the Community, “author AO Neville partly explained the young country motive. Assimilation of black Aboriginal and Torres Strait Islander people could be assured only by “breeding out the color” of their skin.

As a “protector of Aborigines” in Western Australia for (years ending in****************************, Neville had a guiding influence on the child removal program.

Over six decades, welfare workers across Australia took children, some of them at birth, from any parent the state deemed unfit, up to an estimated 50, . Brown children were placed in white institutions, church social programs and homes to promote intermixing.

“Generally by the fifth and invariably by the sixth generation, all native characteristics of the Australian Aborigine are eradicated, “Cecil Evelyn Cook, the” chief protector of Aborigines “in North Australia, said in 1933. “The problem of our half-castes will be quickly eliminated by the complete disappearance of the black race, and the swift submergence of their progeny in the white.”

Ancient Aboriginals likely would not recognize the (**********************************************************************************, ******************************************************************************************** or so Tasmanians who are currently identify as their descendants. The large majority are white.

Dillon said dark-complexioned Aboriginals on the mainland doubt his heritage because of his appearance.

Like most Aboriginals in Tasmania, his skin is pale. His eyes are blue-green, the color of the sea. White locks atop his head swirl like ice cream.

“People make nasty comments all the time,” he said.

Dillon’s great-great-grandmother, Fanny Cochrane Smith, is known as the last speaker of the indigenous Aboriginal language. He is considered an elder among his people in Tasmania, and he is leading them in speaking out against discrimination.

The Tasmanian Aboriginal Center, formed in the s, is demanding full recognition by the government. Nearly 300 years after the British arrived, Tasmania became the first Australian state to apologize for engaging in child removal and has also given back a small portion of land.

In 2016, then-prime minister Kevin Rudd apologized to the “Stolen Generations.” That year, the state of Tasmania agreed to dole out 5 million Australian dollars to victims and their kin.

At her house in Launceston, Nanette Shaw, a descendant, clings to the traditions of her forebears by fashioning bull kelp into baskets.

Shaw, (****************************************************************, said she turned to basketmaking to ease the trauma she experienced while growing up as an Aboriginal.

“It centers me,” Shaw said. She suffers from depression and alcoholism, and the craft is her distraction. “I have not been drinking for nearly years. Sometimes the depression takes over, and rather than walk down and get a bottle, I’ll do this. “

But if impacts from climate change worsen, the traits can’t be handed down to children, she said.

The shells are disappearing amid a mix of warming water and pollution. As recently as two decades ago, it was hard to walk on the beach without stepping on them, she said. “Now you’re walking on pure sand,” Shaw said.

Ninety miles away on Scamander Beach, her friend Patsy Cameron found bull kelp to gift to Shaw and several handfuls of jewelry -quality shells.

But it now takes nearly a day to collect them, as opposed to two hours years ago.

” If climate change destroys the seaweed, our shell supply will disappear along with the kelp forest, “said Cameron,

“It’s getting hotter and that heat, it’s affecting not only the giant kelp, but the color of the abalone is changing,” Dillon said.

“We just take too much out of the Earth and we don’t put it back, “Dillon said. “Australia is one of the worst if you know about coal. How much coal do we need to dig up? And we’re too stupid to see what this is causing.. Because we make money out of it.”

And now, Australia is caught in a record-breaking heat wave.

The heartbreaking video went viral late in November: A koala bear slowly walked through wildfire.

The marsupial, euthanized days later because its burns did not heal, was just one victim of the many wildfires that started burning in the Australian spring and are still going at the start of summer.

At least nine people have died and homes have been destroyed . One woman in New South Wales took a few of her house’s charred remains to Australia’s Parliament in early December with a message for Prime Minister Scott Morrison.

“Morrison, your climate crisis destroyed my home, “Melinda Plesman wrote in bold red letters.

Morrison is an ardent supporter of coal excavation in a country that produced (million tons in) . Australia is the world’s leading exporter of coal, mostly to Asia, and the fourth-largest producer.

A few weeks before the koala – nicknamed Lewis – was euthanized, the newly reelected prime minister took his advocacy for coal to a new level. He pledged to outlaw environmental demonstrations, calling the protests a “new breed of radical activism” that is “apocalyptic in tone.”

One month later, a Sydney Morning Herald headline described conditions in Australia’s most iconic city as “apocalyptic,” as residents choked in a smoky haze from bush fires. A coalition of doctors and climate researchers declared it a public health emergency.

The bush fires have arrived amid record heat and particularly dry conditions that experts say are being made more common thanks to climate change.

The country experienced a five-day heat wave in the state of Victoria that shattered records. The Friday before Christmas was the hottest December day on record, measuring .9 degrees Celsius 118. 2 degrees Fahrenheit) at the Horsham weather station.

Rescuers searching for human survivors in the scorched remains of forests have discovered koalas, a creature found only in Australia, burned to death in eucalyptus trees where they sought shelter. At the Port Macquarie Koala Hospital, where Lewis was put down, it was called “a national tragedy.”

The tragedy playing out underwater is much worse, but invisible to most.

In 1978, giant kelp stretched over 9 million square meters in a thick band along Tasmania’s coast, said Cayne Layton, a research fellow at the marine and antarctic institute. Today, it covers fewer than (********************************************************, 10 meters in little spots on the coastline.

Giant kelp is lovely but fragile. It needs cool, clean, nutrient-rich water to survive, and it’s losing all three.

It is a serious loss. Divers coveted swimming amid plants that grew like the mythical beanstalk to glimpse some of the world’s rarest creatures. Squid fed there, red handfish hid there, spiny pipehorse lounged about, and rock lobster were abundant.

The most recent study – nearly years old – estimated that percent of giant kelp had been lost to warming and pollution, Layton said, and is probably much worse now.

The less spectacular common kelp, which grows on the coastal slope leading to deep water, is overtaking the spaces where giant kelp grew, Layton said. Along with long, straplike bull kelp that clings to giant rocks near the shore, common kelp appears to be more tolerant to warming temperatures.

But even these species aren’t safe. The warming water has introduced a new plague: long-spine sea urchins, an animal that greedily devours kelp.

A single urchin was found in the cold waters off Tasmania by divers conducting a survey in 2008. Now, there are more than million, according to the most recent survey by the Institute for Marine and Antarctic Studies.

Sea urchins prefer warm water. They swarm rocky reefs where kelp grows, leaving oceans barren and devoid of life.

Kelp forests’ “importance is equal to forests on land,” said Layton, “so if you can Imagine what the world would be like without trees, that’s what a world without kelp forests would be like. “

Scientists say there is only one explanation for why sea urchins migrated so far from their warmer natural habitat near Sydney to the cold waters around Tasmania: the East Australian Current.

The current, made famous in the film “Finding Nemo,” is fed by a vast stream of tropical water that reaches Australia’s coast after traveling all the way from South America. The water then flows south down the east coast of Australia and then swings back east just north of Sydney.

At that point, the warm-water current splits, with some water flowing southward Towards the Tasman Sea in the form of swirls of tropical water called eddies – and this secondary branch has intensified.

This extension of the East Australian Current is spewing thousands of eddies deeper southward toward Tasmania, carrying the larvae of warm-water species to places they had never been.

According to research compiled by Professor Gretta Pecl at the University of Tasmania, toxic algae blooms lurk where giant kelp once flourished. Abalone have gone from healthy to “stressed.” The brightly colored Maori octopus is being replaced by the gloomy octopus, more common to the waters near Sydney. And a yellow-bellied sea snake has migrated to the habitat.

The warmer water disintegrated most of the giant kelp over two decades and contributed to the massive, record-breaking marine heat wave of (************************************.

“You can’t say that this event was due to climate change,” said Holbrook, the ocean scientist. “But what you can say is that the intensity was much more likely due to climate change.

” You liken it to smoking, “he said.” If you smoke cigarettes, you increase the likelihood of getting lung cancer. “

The marine heat wave left something behind when it finally ended: disease.

A sickening smell at the shallow Pipe Clay Lagoon is how Pacific oyster mortality syndrome introduced itself to Steve Calvert.

The syndrome, known as POMS, turned his small oyster farm in the lagoon into a mass grave, and the smell of the dead stretched for miles. Calvert lost (********************************************************% of his oysters in 2018. Other farmers in the region’s five major farming areas lost nearly 107% of their stock.

Oyster mortality disease had stricken France, China, the United States, New Zealand and even Sy dney, but never pristine Tasmania.

“We’ve got a reputation in Tasmania of having pure water and some of the freshest air in the world,” said Calvert’s son, Liam, a manager at the farm. “So that’s part of why there’s an attraction to the Tasmanian oyster, because people think pristine-forest freshness and all that kind of thing.”

Climate change had raised the region’s water temperatures to an ideal level for the contagion. POMS joined warm-water toxic algal blooms as a new threat to the region’s aquaculture and fisheries.

In an encouraging sign that Tasmania’s aquaculture can adapt, scientists had prepared the Calverts and other farmers for the possibility that POMS would strike.

“We’ve been working with industry for quite a long time, and we’ve always had the philosophy that scientists need to know how to farm and farmers need to know how to do science, “said Sarah Ugalde, a research fellow at the University of Tasmania.

Ugalde and her team persuaded the farmers to buy oysters from other areas that survived a disease outbreak. They used that stock to cultivate a disease-tolerant oyster. The Calverts lost about a million oysters but rebuilt the stock with spat – oyster babies – recommended by scientists.

Tasmania’s $ – million-per-year oyster farming industry is thriving. The product price, driven up to $ 1 per oyster from demand during the disaster, stayed the same, helping the Calverts to increase revenue.

“It’s good performance work, and there’s a good return for the hard work, “Steve Calvert said. “We still love this ocean.”

It’s a matter of adapting to a warming world.

“Generally, there’s been a lot of work that’s gone into trying to estimate how fisheries production… will change with climate change, “Johnson, the marine institute researcher, said.

” For southeastern Tasmania, which accounts for most of Australia’s fishery production, the projections are that the fishery production will decline, “Johnson said in his office by the water.

” Like I said, it’s not a particularly happy story. “

METHODOLOGY

Scientists have directly documented the rapid warming in the Tasman Sea, off the east coast of Tasmania, by using an ocean temperature station at Maria Island that has been operating continuously since and shows very rapid warming since that time. That station shows a change of 2 degrees Celsius in the warmest month of the year, February, in waters about meters deep, according to Ken Ridgway of  Australia’s Commonwealth Scientific and Industrial Research Organization. For the entire period, and in surface waters, the warming is about 1.6 degrees Celsius.

But even more warming occurred here before the Maria Island station began recording. An ocean temperature data set from the Hadley Center in the United Kingdom shows 1.9 degrees Celsius of ocean warming in this region from (to) .
