Canadian delegation set to tell COP27 about oceans’ role in fighting climate change

Published

Lying in plain sight and lapping against our shores is what scientists describe as an unsung hero that has been quietly absorbing heat and keeping the world’s temperatures under control. And over the coming days, a group of Canadian researchers hopes to persuade the world that the ocean has a crucial role to play in fighting climate change.

Prof. Anya Waite is leading a delegation from Dalhousie University’s Ocean Frontier Institute to attend the 27th annual Conference of the Parties of the U.N. Framework Convention on Climate Change — better known as COP27 — in Sharm el-Sheikh, Egypt, starting Sunday. They plan to share ways the deep blue carbon sink acts as a buffer and impacts climate forecasts.

Waite said most people know that rainforests are the lungs of the planet, keeping temperatures down and filtering the air.

“But oceans hold more carbon than all the rainforests on Earth,” she said in an interview. “And deep blue carbon is carbon that’s held by the deep blue sea. So the open ocean, the high seas, which go down to 4000 meters in depth … they hold most of the carbon on Earth. And that’s something people really aren’t aware of.”

Scientists must understand the role oceans have played to date in mitigating climate change, she said, noting it’s also important for coastal communities to know how they must adapt to shifting conditions.

Oceans have absorbed 90 per cent of the earth’s heat emissions so far, Waite said. She credits oceans for the fact the world has not yet blown through the goals set out in the Paris Agreement, the international climate pact that pledged to limit warming to below two degrees Celsius and curb it to 1.5 if possible.

But there is a danger that these carbon sinks will turn to emitters as the waters warm, melting caps of frozen methane and other greenhouse gases that lie scattered on the sea floor, she said.

“The capacity of the ocean to absorb carbon is gently declining,” Waite said. “But then on top of that we’re seeing that there’s these … extreme events or rare events that can potentially release carbon in short notice. And we don’t really understand those.”

Scientists and communities are beginning to understand the importance of common shoreline features such as marshes, kelp forests and sea grass meadows that keep blue carbon rooted in the soil, she said.

Waite said such “blue carbon ecosystems” help retain emissions, in addition to enhancing biodiversity. But it is further offshore that the biggest carbon stores are to be found, she said.

Changes in ocean temperatures also change water currents, she noted, adding melting glaciers from the Arctic put fresh water into the ocean and force marine animals to either relocate or adapt to their changing environments.

The endangered North Atlantic right whale, for instance, has moved from the Gulf of Maine it used to call home into the Gulf of St. Lawrence.

“There’s a whole lot more shipping in the St. Lawrence, and those animals are now coming in contact with ships way more often, bringing an already endangered species to the brink of collapse,” Waite said.

Shifts in ocean circulation and temperatures also change animal behavior, sometimes causing them to move in search of more comfortable environs that ultimately put them at greater risk.

Canada is uniquely positioned to tap into the ocean’s potential benefits, Waite said, noting the country is surrounded by wide open spaces of water on three sides. But though Canada has the luxury of using the deep blue to balance its carbon output, she said the issue has received limited attention and financial resources so far.

“Climate change is essentially a multi-billion dollar problem. And yet to observe and care for the oceans costs, way less than that,” she said. “So a small investment can bring an enormous benefit for humankind. The problem we have is that the ocean is sort of out of sight, out of mind.”

Australia plans a social media ban for children under 16

Published

 on

 

MELBOURNE, Australia (AP) — The Australian government announced on Thursday what it described as world-leading legislation that would institute an age limit of 16 years for children to start using social media, and hold platforms responsible for ensuring compliance.

“Social media is doing harm to our kids and I’m calling time on it,” Prime Minister Anthony Albanese said.

The legislation will be introduced in Parliament during its final two weeks in session this year, which begin on Nov. 18. The age limit would take effect 12 months after the law is passed, Albanese told reporters.

The platforms including X, TikTok, Instagram and Facebook would need to use that year to work out how to exclude Australian children younger than 16.

“I’ve spoken to thousands of parents, grandparents, aunties and uncles. They, like me, are worried sick about the safety of our kids online,” Albanese said.

The proposal comes as governments around the world are wrestling with how to supervise young people’s use of technologies like smartphones and social media.

Social media platforms would be penalized for breaching the age limit, but under-age children and their parents would not.

“The onus will be on social media platforms to demonstrate they are taking reasonable steps to prevent access. The onus won’t be on parents or young people,” Albanese said.

Antigone Davis, head of safety at Meta, which owns Facebook and Instagram, said the company would respect any age limitations the government wants to introduce.

“However, what’s missing is a deeper discussion on how we implement protections, otherwise we risk making ourselves feel better, like we have taken action, but teens and parents will not find themselves in a better place,” Davis said in a statement.

She added that stronger tools in app stores and operating systems for parents to control what apps their children can use would be a “simple and effective solution.”

X did not immediately respond to a request for comment on Thursday. TikTok declined to comment.

The Digital Industry Group Inc., an advocate for the digital industry in Australia, described the age limit as a “20th Century response to 21st Century challenges.”

“Rather than blocking access through bans, we need to take a balanced approach to create age-appropriate spaces, build digital literacy and protect young people from online harm,” DIGI managing director Sunita Bose said in a statement.

More than 140 Australian and international academics with expertise in fields related to technology and child welfare signed an open letter to Albanese last month opposing a social media age limit as “too blunt an instrument to address risks effectively.”

Jackie Hallan, a director at the youth mental health service ReachOut, opposed the ban. She said 73% of young people across Australia accessing mental health support did so through social media.

“We’re uncomfortable with the ban. We think young people are likely to circumvent a ban and our concern is that it really drives the behavior underground and then if things go wrong, young people are less likely to get support from parents and carers because they’re worried about getting in trouble,” Hallan said.

Child psychologist Philip Tam said a minimum age of 12 or 13 would have been more enforceable.

“My real fear honestly is that the problem of social media will simply be driven underground,” Tam said.

Australian National University lawyer Associate Prof. Faith Gordon feared separating children from there platforms could create pressures within families.

Albanese said there would be exclusions and exemptions in circumstances such as a need to continue access to educational services.

But parental consent would not entitle a child under 16 to access social media.

Earlier this year, the government began a trial of age-restriciton technologies. Australia’s eSafety Commissioner, the online watchdog that will police compliance, will use the results of that trial to provide platforms with guidance on what reasonable steps they can take.

Communications Minister Michelle Rowland said the year-long lead-in would ensure the age limit could be implemented in a “very practical way.”

“There does need to be enhanced penalties to ensure compliance,” Rowland said.

“Every company that operates in Australia, whether domiciled here or otherwise, is expected and must comply with Australian law or face the consequences,” she added.

The main opposition party has given in-principle support for an age limit at 16.

Opposition lawmaker Paul Fletcher said the platforms already had the technology to enforce such an age ban.

“It’s not really a technical viability question, it’s a question of their readiness to do it and will they incur the cost to do it,” Fletcher told Australian Broadcasting Corp.

“The platforms say: ’It’s all too hard, we can’t do it, Australia will become a backwater, it won’t possibly work.’ But if you have well-drafted legislation and you stick to your guns, you can get the outcomes,” Fletcher added.

A tiny grain of nuclear fuel is pulled from ruined Japanese nuclear plant, in a step toward cleanup

Published

TOKYO (AP) — A robot that has spent months inside the ruins of a nuclear reactor at the tsunami-hit Fukushima Daiichi plant delivered a tiny sample of melted nuclear fuel on Thursday, in what plant officials said was a step toward beginning the cleanup of hundreds of tons of melted fuel debris.

The sample, the size of a grain of rice, was placed into a secure container, marking the end of the mission, according to Tokyo Electric Power Company Holdings, which manages the plant. It is being transported to a glove box for size and weight measurements before being sent to outside laboratories for detailed analyses over the coming months.

Plant chief Akira Ono has said it will provide key data to plan a decommissioning strategy, develop necessary technology and robots and learn how the accident had developed.

The first sample alone is not enough and additional small-scale sampling missions will be necessary in order to obtain more data, TEPCO spokesperson Kenichi Takahara told reporters Thursday. “It may take time, but we will steadily tackle decommissioning,” Takahara said.

Despite multiple probes in the years since the 2011 disaster that wrecked the. plant and forced thousands of nearby residents to leave their homes, much about the site’s highly radioactive interior remains a mystery.

The sample, the first to be retrieved from inside a reactor, was significantly less radioactive than expected. Officials had been concerned that it might be too radioactive to be safely tested even with heavy protective gear, and set an upper limit for removal out of the reactor. The sample came in well under the limit.

That’s led some to question whether the robot extracted the nuclear fuel it was looking for from an area in which previous probes have detected much higher levels of radioactive contamination, but TEPCO officials insist they believe the sample is melted fuel.

The extendable robot, nicknamed Telesco, first began its mission August with a plan for a two-week round trip, after previous missions had been delayed since 2021. But progress was suspended twice due to mishaps — the first involving an assembly error that took nearly three weeks to fix, and the second a camera failure.

On Oct. 30, it clipped a sample weighting less than 3 grams (.01 ounces) from the surface of a mound of melted fuel debris sitting on the bottom of the primary containment vessel of the Unit 2 reactor, TEPCO said.

Three days later, the robot returned to an enclosed container, as workers in full hazmat gear slowly pulled it out.

On Thursday, the gravel, whose radioactivity earlier this week recorded far below the upper limit set for its environmental and health safety, was placed into a safe container for removal out of the compartment.

The sample return marks the first time the melted fuel is retrieved out of the containment vessel.

Fukushima Daiichi lost its key cooling systems during a 2011 earthquake and tsunami, causing meltdowns in its three reactors. An estimated 880 tons of fatally radioactive melted fuel remains in them.

The government and TEPCO have set a 30-to-40-year target to finish the cleanup by 2051, which experts say is overly optimistic and should be updated. Some say it would take for a century or longer.

Chief Cabinet Secretary Yoshimasa Hayashi said there have been some delays but “there will be no impact on the entire decommissioning process.”

No specific plans for the full removal of the fuel debris or its final disposal have been decided.

Strong typhoon threatens northern Philippine region still recovering from back-to-back storms

Published

MANILA, Philippines (AP) — A strong typhoon was forecast to hit the northern Philippines on Thursday, prompting a new round of evacuations in a region still recovering from back-to-back storms a few weeks ago.

Typhoon Yinxing is the 13th to batter the disaster-prone Southeast Asian nation this season.

“I really pity our people but all of them are tough,” Gov. Marilou Cayco of the province of Batanes said by telephone. Her province was ravaged by recent destructive storms and is expected to be affected by Yinxing’s fierce wind and rain.

Tens of thousands of villagers were returning to emergency shelters and disaster-response teams were again put on alert in Cagayan and other northern provinces near the expected path of Yinxing. The typhoon was located about 175 kilometers (109 miles) east of Aparri town in Cagayan province on Thursday morning.

The slow-moving typhoon, locally named Marce, was packing sustained winds of up to 165 kilometers (102 miles) per hour and gusts of up to 205 kph (127 mph) and was forecast to hit or come very near to the coast of Cagayan and outlying islands later Thursday.

The coast guard, army, air force and police were put on alert. Inter-island ferries and cargo services and domestic flights were suspended in northern provinces.

Tropical Storm Trami and Typhoon Kong-rey hit the northern Philippines in recent weeks, leaving at least 151 people dead and affecting nearly 9 million others. More than 14 billion pesos ($241 million) worth of rice, corn and other crops and infrastructure were damaged.

The deaths and destruction from the storms prompted President Ferdinand Marcos Jr. to declare a day of national mourning on Monday when he visited the worst-hit province of Batangas, south of the capital, Manila. At least 61 people perished in the coastal province.

Trami dumped one to two months’ worth of rain in just 24 hours in some regions, including in Batangas.

“We want to avoid the loss of lives due to calamities,” Marcos said in Talisay town in Batangas, where he brought key Cabinet members to reassure storm victims of rapid government help. “Storms nowadays are more intense, extensive and powerful.”

In 2013, Typhoon Haiyan, one of the strongest recorded tropical cyclones, left more than 7,300 people dead or missing, flattened entire villages and caused ships to run aground and smash into houses in the central Philippines.
