How his plan to open the Canadian Rockies to coal mining set Alberta’s Jason Kenney against country music stars

By Alex BoydCalgary Bureau
Sun., Aug. 15, 2021


Corb Lund is not enjoying this interview.

The lanky Juno-winning musician, known for his playful lyrical takes on rural life on the Prairies, is calling while on his way home to southern Alberta after a stint in studio in Edmonton working on some new music. But he hasn’t phoned to talk about his latest project, or even the one before it, an album released to critical acclaim in the middle of a pandemic.

Instead, he’s stolen time from his primary gig to talk about a side project that has recently rebranded him as an emerging, albeit reluctant, advocate: stopping a controversial plan to open up the Rocky Mountains to coal mining.

“I would rather be playing music, frankly,” says Lund, sounding exasperated.

“I blame the government. I don’t even blame the coal companies, because coal companies are going to coal-company, right? That’s what they do. It’s the government allowing them to do it.”




Last spring, the Alberta government set off a firestorm with the quiet removal of a 44-year-old policy preventing most open pit coal mining in the iconic mountain range. At a time when pandemic polarization seems to have split Albertans into warring camps on just about everything, coal mining might be one of the few areas of common ground.

In short, most people are mad.


The provincial government maintains that a new plan is required because the old coal policy was “largely made obsolete through more modern oversight,” Jennifer Henshaw, press secretary to Energy Minister Sonya Savage, said in an email. The old one doesn’t even mention climate change, she points out.

The mines would also bring in revenue at a time when the province is struggling to recover from the double whammy of the pandemic and plummeting oil revenue — in 2017, the Alberta government collected $15.7 million from coal production on publicly owned land.

But the anger is such that the current government, which flaunts big trucks and cowboy hats with an enthusiasm that’s notable, even for Albertan politicians — Premier Jason Kenney is preparing for a tour of the province in his signature blue pickup truck — is facing pushback from what might seem like an unexpected source: country music stars.

Alberta’s conservative history can tempt outsiders to paint the whole province with the same political brush, an impression reinforced by the current government, which has embraced the rural parts of the province as its base.

But its coal plans have united environmentalists, many conservatives and several First Nations as well as big country names, exposing the many shades of grey in terms of how Albertans think of political allegiance, resource development and even the future of their province.

“I know that some of the current politicians tried to frame this as a bunch of urban busybodies but honestly, I know more rural people against it,” Lund says.

“It’s a very wide coalition of people.”

A rising chorus


Over the past six months, a movement of sorts has coalesced around Lund, who, in addition to speaking out in interviews and online, has hosted a horse ride and a protest concert in the sprawling ranch country located in the mountain foothills south of Banff National Park. He’s even publicly mused about attempting a referendum under new government legislation that allows private citizens to put issues to the ballot.

One by one, other members of Canadian country royalty have joined the chorus.

Paul Brandt, whose hit songs include “Alberta Bound,” once used as a soundtrack for Ford commercials, tweeted that “Corb Lund is right,” alongside photos of him fishing in a gleaming stream. Terri Clark tweeted that the Canadian Rockies are “part of my soul” and linked to Lund’s Facebook page.




In a video posted online, Terry Grant, otherwise known as “Mantracker,” from the show of the same name in which he used tracking skills and a horse to hunt down contestants, came out strongly against the mine. “I grew up down there, chasing cows and cowboying, guiding and hunting. It’s amazing country.”

Of course, there will always be critics who argue that entertainers should stay out of politics.

Corb Lund is usually one of those critics.

“I don’t normally speak about stuff like this,” he says. “A lot of times when people in positions of notoriety or celebrity or whatever speak out about stuff, they don’t really know what they’re talking about. They’re kind of stupid, and I didn’t want to be that guy.”

To that end, in the past few months, he’s taken on a crash course in coal, speaking to politicians, coal lobbies, scientists and conservationists.

The Rockies are iconic to Albertans, and the opposition is built on concerns that mines will open up vast pits to extract the coal beneath, and at the same time pollute the water, harm wildlife and knit access roads and rail lines across land that is in many ways undisturbed.

Before a long weekend in May


The furor began over a year ago, with an email sent to media on the Friday afternoon before the May long weekend. In it, the government announced it was replacing the “outdated” 44-year-old coal policy that had prohibited much mining in the Rockies.

Instead, the government was bringing in what it called “modern regulatory processes, integrated planning and land use policies.” While the government said sensitive land in the eastern slopes, for example, would continue to be protected, coal companies would be able to apply to develop new projects.

“Government is placing a strong focus on creating the necessary conditions for the growth of export coal production,” the release read.

The reaction was swift.


The Alberta Wilderness Association pointed out the move had the potential to open up more than 4.7 million hectares of environmentally sensitive lands to coal exploration. A group of ranchers whose grazing leases were suddenly eligible for mining, and the Ermineskin and Whitefish Lake First Nations moved ahead with legal action, arguing the changes had been made without required consultation.

In January, the government said it had “listened carefully” and announced it was cancelling 11 coal leases and would pause any future lease sales. The old policy was eventually reinstated while a five-member panel was tasked with consulting with Albertans about a new way forward. Suggesting how widely the issue resonated, a preliminary survey done by the panel found the majority of Albertans felt the development of coal affected them.

Meanwhile, the federal government has waded into the fray, armed with the argument that issues of climate change and pollution are national matters.

Federal Environment Minister Jonathan Wilkinson announced in June that Ottawa would conduct an environmental review of any new coal project that could potentially release selenium, a mineral found in Alberta’s coal beds that is toxic to fish.

Last week, Ottawa rejected the Grassy Mountain proposal, one of the most high-profile projects, after a joint review panel concluded it would have major environmental effects.

But the real litmus test will come this fall, when the Alberta government goes back to the drawing board on a new coal policy.

Alberta premiers — then and now



Most of the coal currently being eyed by commercial interests in Alberta lies within a 20-kilometre-wide band of rolling foothills that runs along the eastern edge of the Rockies south of Banff National Park.

Falling roughly between a winding secondary highway known as the Cowboy Trail — a nod to decades of local ranching history — and the Rockies proper, the eastern slopes are considered one of the last patches of the true Prairie ecosystem that once blanketed much of the continent.

It’s important habitat for grizzly bears and threatened species such as westslope cutthroat trout; and the water that flows through here feeds much of the southern half of the province — including the city of Calgary.

Coal mining is not unheard of in this part of the world. To the south, the Crowsnest Pass, one of the few passable routes between Alberta and British Columbia, is still shot through with old mine shafts. But the use of coal for energy waned in the 1960s and then, in 1976, Alberta brought in a coal policy that put management of water first and restricted much new coal development.

At the time, David Luff was a brand new government employee who had been hired the year before to help implement the coal policy and develop a plan for the eastern slopes.

The premier of the day, Peter Lougheed, still casts a long shadow in Alberta politics. Luff says he believes Lougheed, through the coal policy, was implementing a long-term vision of stability and prosperity for the province that Luff argues was ahead of its time.

“In 1976, people didn’t talk about climate change, they weren’t worried about drought. They weren’t worried about the forest fires that we now see on a yearly basis,” he says. “None of that was really on anyone’s radar.”

The policy protected much of the land and encouraged coal companies, which had to get special permission for most open-pit mines in Alberta, to move to B.C., where mines have released so much selenium it’s now ending up in Montana.

Since the removal of the Lougheed-era policy, Luff says companies have already begun to explore future mine sites, building roads and sinking core holes into the rock to probe for coal.

“With the rescinding of the policy, the government was stating water is no longer important. Water is not the highest priority; coal development is the highest priority. And Albertans found that to be fundamentally wrong,” Luff says.

A different kind of coal


Coal is one of the emerging villains of the fight against climate change, and Canada has committed to phasing out coal-fired electricity by 2030. Alberta is currently on track to accomplish that even earlier and hopes to transition off by 2023, officials say.

But a complicating factor here is there are different types of coal. Much of what the Alberta government is looking to produce is what’s called metallurgical coal. With more carbon and less ash and moisture than regular coal, also known as thermal coal, metallurgical coal is used to make steel and even Canada says it can’t be phased out just yet.

According to the provincial website, Alberta still produces about 25 million to 30 million tonnes of coal every year from its remaining nine mines — two of which produce metallurgical coal, and the remaining seven of which are devoted to thermal, much of which is sold to other countries.

But the federal environment minister says that while the first priority is eliminating thermal coal, eventually the same thing will happen to metallurgical.

“There are a number of different processes and technologies that people are looking to deploy that will help us to reduce those emissions and move us away from metallurgical coal,” Wilkinson said, pointing to a couple of Canadian companies that are trying out electric furnaces to make steel.

Luff, for his part, is not anti-industry. He would go on to become an assistant deputy minister in the energy department, then become a vice-president for the Canadian Association for Petroleum Producers before creating his own consultancy company, but he worries that government is putting profit ahead of the long-term interests of Albertans.

He worries Alberta’s politicians aren’t playing the long game here, which he argues shows industry switching away from coal, even for steel production. The potential risk to the province’s drinking water and an iconic part of the province won’t be done away with so easily.

“Maybe it’s just a lack of understanding that, yes, Alberta is a province that benefits from the development of its resources, whether it’s oil and gas, or timber development and so on. But Albertans also recreate, and spend a great deal of time in the mountains, in northern Alberta in the boreal forest — hiking, canoeing, fishing, hunting — and many Canadians, I don’t think, are aware of that,” he says.

“Albertans do look to find a balance between the development of resources, but also ensuring that the environment and social values will be maintained in perpetuity.”

‘I don’t know what he’s thinking’


Two and a half years into its maiden term — a significant chunk of which involved navigating a global pandemic — Jason Kenney’s United Conservative government is no stranger to controversy.

There was the time at least seven MLAs and senior government officials were caught travelling for the holidays despite official advice, or the time Kenney himself was photographed having drinks on the balcony of the so-called Sky Palace — a government office that a former premier tried to turn into a luxury apartment that is now Albertan shorthand for government arrogance — with a group of ministers, including the health minister, while flouting pandemic rules.

There is growing evidence Albertans are getting fed up. While many leaders have enjoyed pandemic bumps to their approval ratings, Kenney has the lowest level of support of a premier in the country.

According to an Angus Reid poll from June, his approval was sitting around 31 per cent, or about half of where it was when he swept to victory two years ago.

But while much of the pushback against Kenney’s government has tended to splinter along political lines — his rule-resistant COVID-19 response seemed designed to appease a rural base, experts say — the fury of coal stands out for its cross-partisan appeal.

When he was running to be leader of the newly minted United Conservative party four years ago, Kenney stood in front of a green and white sign emblazoned with his signature and what he called the Grassroots Guarantee — a promise that policy would be developed by membership and not by leadership alone.


It was an attempt to throw off the shackles of conservative arrogance in the province, and yet it’s been a challenging promise to deliver on, says Lori Williams, a political scientist at Calgary’s Mount Royal University.

A small poll in February found that almost seven in 10 Albertans surveyed were against development of formerly protected areas and half strongly opposed getting rid of the coal policy specifically and yet the government has plunged ahead with changes. Some government MLAs have spoken of an inability to get Kenney’s ear.

“The inability to respond to the concerns that are being raised by his base is a bit surprising,” Williams says.

Kenney came to power by combining the province’s two Conservative parties, and as his popularity drops, it’s a partnership that risks unravelling. He’s struggled to keep the right wing of the party intact, which some have speculated explains why he’s pushed ahead with the development often favoured by the right.

“I don’t know what he’s thinking,” Williams says. “I often wonder if he knows the Alberta that he is now governing; it’s not the Alberta that he left in the 1990s. But sometimes he governs as if it is that Alberta.”

‘This is just about me not wanting the Rockies ruined’

Lund, who says he agrees with some ideas on the right and some on the left, says this isn’t about politics.

“I don’t like any political parties. I don’t like groups of people in general. I don’t trust them. I only trust individuals. So this is just about me not wanting the Rockies ruined for everyone,” he says. “And turns out that’s resonated across political lines.”

Fellow musician Brett Kissel was raised on a ranch north of Edmonton but grew up on country music stages — he recorded his first album at age 12 and has since had four singles hit No. 1 on Canadian country music charts. After watching one of Lund’s videos about coal this spring, he immediately called him to ask how he could help, he says.

He agrees this is not about politics. He’s made public appearances with Kenney and says there are a number of things the current government has done well since the pandemic began.



Personal relationships aside, he says, he’s decided to speak out because of what he considers a “bad deal” for Alberta. As he sees it, the government has backed itself into a corner — if it backs down now, it will invite environmentalists to fight back on other causes. But he argues that the time has come for the province to heed the voices of the province.

Speaking a few hours before stepping onto the stage in Quebec for one of his first post-pandemic appearances this month, he said it’s a comment on Alberta politics when even the “true blue Albertans” are starting to push back.

“We’re pro oil. We’re pro industry. We’re pro money. We’re pro generational wealth. So even us, we’re the ones who are like, ‘Yeah, no, this is too far,’” Kissel says.

He says he feels for the people who work in coal who were looking forward to new opportunities — only to have those new mines threated by the pushback. The musicians who have spoken out have all received significant heat for that reason, he says.

Still, he calls the mine proposals a “bad deal” for the province, with the promise of a few hundred local jobs and “miniscule” royalties.

“It’s very difficult when we are talking about other people’s livelihoods,” he says. “But you know what, the pros for this situation do not outweigh the cons that are going to be for the rest of the province.”

Right now, the government is awaiting the coal policy committee’s report, which is due by Nov. 15. Although “we cannot speculate on the content or details of a modernized provincial coal policy,” the report will “inform” the new plan, the Alberta energy minister’s press secretary said in an email.

A clearer timeline for a new policy is expected this fall.

Lund and others will be watching.

“I feel like the wind is in our sails, but I think we need to keep pushing until we have a new policy in place that clearly sorts this out so that we don’t have to deal with it again, five years from now,” he says.

“In this divided time, it’s been refreshing to see that we can all agree on clean water at least, right?”

Rare Checkmate Makes Commentator Freak Out

How a simple crystal could help pave the way to full-scale quantum computing
August 13, 2021 

Vaccine and drug development, artificial intelligence, transport and logistics, climate science — these are all areas that stand to be transformed by the development of a full-scale quantum computer. And there has been explosive growth in quantum computing investment over the past decade.

Yet current quantum processors are relatively small in scale, with fewer than 100 qubits — the basic building blocks of a quantum computer. Bits are the smallest unit of information in computing, and the term qubits stems from “quantum bits”.

While early quantum processors have been crucial for demonstrating the potential of quantum computing, realising globally significant applications will likely require processors with upwards of a million qubits.

Our new research tackles a core problem at the heart of scaling up quantum computers: how do we go from controlling just a few qubits, to controlling millions? In research published today in Science Advances, we reveal a new technology that may offer a solution.

What exactly is a quantum computer?


Quantum computers use qubits to hold and process quantum information. Unlike the bits of information in classical computers, qubits make use of the quantum properties of nature, known as “superposition” and “entanglement”, to perform some calculations much faster than their classical counterparts.

Unlike a classical bit, which is represented by either 0 or 1, a qubit can exist in two states (that is, 0 and 1) at the same time. This is what we refer to as a superposition state.

Demonstrations by Google and others have shown even current, early-stage quantum computers can outperform the most powerful supercomputers on the planet for a highly specialised (albeit not particularly useful) task — reaching a milestone we call quantum supremacy.

Google’s quantum computer, built from superconducting electrical circuits, had just 53 qubits and was cooled to a temperature below -273℃ in a high-tech refrigerator. This extreme temperature is needed to remove heat, which can introduce errors to the fragile qubits. While such demonstrations are important, the challenge now is to build quantum processors with many more qubits.

Major efforts are underway at UNSW Sydney to make quantum computers from the same material used in everyday computer chips: silicon. A conventional silicon chip is thumbnail-sized and packs in several billion bits, so the prospect of using this technology to build a quantum computer is compelling.

Read more: Quantum computers could arrive sooner if we build them with traditional silicon technology


The control problem

In silicon quantum processors, information is stored in individual electrons, which are trapped beneath small electrodes at the chip’s surface. Specifically, the qubit is coded into the electron’s spin. It can be pictured as a small compass inside the electron. The needle of the compass can point north or south, which represents the 0 and 1 states.

To set a qubit in a superposition state (both 0 and 1), an operation that occurs in all quantum computations, a control signal must be directed to the desired qubit. For qubits in silicon, this control signal is in the form of a microwave field, much like the ones used to carry phone calls over a 5G network. The microwaves interact with the electron and cause its spin (compass needle) to rotate.

Currently, each qubit requires its own microwave control field. It is delivered to the quantum chip through a cable running from room temperature down to the bottom of the refrigerator at close to -273℃. Each cable brings heat with it, which must be removed before it reaches the quantum processor.

At around 50 qubits, which is state-of-the-art today, this is difficult but manageable. Current refrigerator technology can cope with the cable heat load. However, it represents a huge hurdle if we’re to use systems with a million qubits or more.

The solution is ‘global’ control


An elegant solution to the challenge of how to deliver control signals to millions of spin qubits was proposed in the late 1990s. The idea of “global control” was simple: broadcast a single microwave control field across the entire quantum processor.

Voltage pulses can be applied locally to qubit electrodes to make the individual qubits interact with the global field (and produce superposition states).

It’s much easier to generate such voltage pulses on-chip than it is to generate multiple microwave fields. The solution requires only a single control cable and removes obtrusive on-chip microwave control circuitry.

For more than two decades global control in quantum computers remained an idea. Researchers could not devise a suitable technology that could be integrated with a quantum chip and generate microwave fields at suitably low powers.

In our work we show that a component known as a dielectric resonator could finally allow this. The dielectric resonator is a small, transparent crystal which traps microwaves for a short period of time.

The trapping of microwaves, a phenomenon known as resonance, allows them to interact with the spin qubits longer and greatly reduces the power of microwaves needed to generate the control field. This was vital to operating the technology inside the refrigerator.

In our experiment, we used the dielectric resonator to generate a control field over an area that could contain up to four million qubits. The quantum chip used in this demonstration was a device with two qubits. We were able to show the microwaves produced by the crystal could flip the spin state of each one.

The path to a full-scale quantum computer

There is still work to be done before this technology is up to the task of controlling a million qubits. For our study, we managed to flip the state of the qubits, but not yet produce arbitrary superposition states.

Experiments are ongoing to demonstrate this critical capability. We’ll also need to further study the impact of the dielectric resonator on other aspects of the quantum processor.

That said, we believe these engineering challenges will ultimately be surmountable — clearing one of the greatest hurdles to realising a large-scale spin-based quantum computer.

The Nation Proving That Oil And Renewables Aren’t Opposed

After decades of world-leading oil and gas production, Norway is looking to stake its claim on a piece of the renewables market. But can the oil giant become a role model for green energy while still earning off its oil legacy? Just two years ago, Norway ranked 15th worldwide for oil production, and eighth for gas. Its longstanding relationship with oil and gas has allowed it to create its $1.4 trillion sovereign wealth fund to ensure that the country does not come to rely on oil and gas alone, by diversifying investments to the non-oil sector. 

In April this year, Norway announced the first investment from the sovereign wealth fund into a renewable energy project. The Norges Bank Investment Management which manages the fund acquired a 50 percent stake in the Borssele offshore wind farm in the Netherlands from Denmark’s Ørsted A/S for $1.63 billion. The project is the second-largest operating wind farm in the world with a capacity of 752 megawatts, providing energy for around 1 million Dutch households every year.

At the local level, Raymond Johansen, Oslo’s governing mayor, has big plans for the Oslo Varme plant, a waste incinerator, which he intends to retrofit with €700m of carbon capture technology. If successful, the plant could be a model for other European cities and support the aim of a 95 percent reduction in Oslo’s carbon emissions by 2030.

As well as investing in renewable energy development, the government is also encouraging the public to make the switch from oil and gas use to alternatives. For example, Norway has waived high taxes charged for traditional cars for electric vehicles (EV), allowing owners to drive Teslas and other EVs in bus lanes, on toll roads for free, to access free parking and charging stations across the country. This is in the hope that only EVs will be sold in the country by as early as 2025.

But as Norway looks to renewable energy for domestic use, planning to make the shift away from gas and oil entirely, its oil production is far from over. The country is, in fact, increasing its oil production for export over the next decade ahead of an inevitable dip in demand as renewable energy becomes more readily available. 

As Norway’s state-owned oil giant Equinor continues its significant exploration and production projects around the world, the country’s oil and gas activities are still going strong. And yet, at the national level, Norway runs almost entirely on renewable power. 

At present, around 200,0000 people are employed in Norway’s oil and gas industry, meaning as the country makes the shift to renewable energy development it must consider the needs and expectations of a Norwegian population that continues to rely heavily on fossil fuels for employment. 

Politicians argue that it is an asset for Norway to have its hands both in oil and gas as well as renewables as it has a longstanding history in the industry and can provide cleaner fossil fuel production, by adopting carbon capture and storage technologies to lower emissions, than its competitors. 

Petroleum and Energy Minister Tina Bru explained, “I do not have a bad conscience for Norway being an ambitious climate nation at the same time as we have oil and gas production,” suggesting that her party would not be following the IEA road map because “if we were to decide tomorrow that we’ll stop producing oil and gas on the Norwegian shelf, other countries will say: ‘Okay, we will supply this’.”

As many criticize Norway for apparent hypocrisy, being both an oil and gas as well as a renewable energy leader may actually play to the country’s advantage. By developing a world-leading renewables sector while working to adapt its oil and gas production to become cleaner, Norway could continue to lead the way in both industries, ultimately encouraging others to adopt better practices.

Central Alberta anti-lockdown activist suing province, health officials over COVID orders

Challenge alleges Christopher Scott’s freedom of expression and peaceful gathering rights violated

PAUL COWLEY
Aug. 12, 2021

Anti-lockdown activist and Mirror café owner Chris Scott is suing the province, arguing his constitutional rights were violated.

The legal action filed last month by Scott’s Calgary lawyer, Chad Williamson, names the province, chief medical officer of health Dr. Deena Hinshaw and Alberta Health Services.

It claims health orders that were issued by the province during the height of the COVID-19 pandemic prevented people from gathering for a political purpose and “is unacceptable in a free and democratic liberal society.”

The lawsuit also claims the order violated sections of the Alberta Bill of Rights.

Whistle Stop cafe owner Scott was arrested at an anti-lockdown rally he helped organize on May 8. In June, he was found guilty of violating an injunction prohibiting the protest. Sentencing is expected to take place on Sept. 13.

Williamson said the constitutional challenge seeks a declaration that any orders issued that prevent political gatherings under the guise of public health are unlawful or invalid.

It’s alleged that since March 2020, Scott has been charged with at least eight regulatory infractions under the Public Health Act or other legislation.

An Aug. 26 court date has been scheduled, but the case will almost certainly be adjourned to a later date.

 

500 million measurements on the impact of climate change

500 million measurements on the impact of climate change
The trunk diameter of both plants -- is subject to seasonal rhythms. In 2015, 
the winter was very long; as a result, the dwarf birch showed little growth in late summer.

It is the most comprehensive study of its kind to date. Researchers at the University of Bonn and the University of South-Eastern Norway have studied how two characteristic arctic-alpine plant species respond to global warming. They did this by analyzing almost 500 million of their own readings from the mountainous region of Norway. The analyses show that potential consequences of climate change are extremely dependent on the specific location of the plants and that deciduous species in particular will benefit from warming. The result would be a further increase in the trend toward greening of the arctic-alpine regions. The study is published in the journal Ecosphere.

The Norwegian mountains can be quite inhospitable during the colder months. Nevertheless, there are plants that cope splendidly with the biting temperatures. They include the dwarf birch Betula nana and the black crowberry Empetrum hermaphroditum. Both thrive in arctic-alpine conditions, which makes them typical representatives of tundra vegetation.

Up until now, it has been unclear how the growth of dwarf birch and crowberry is influenced by specific environmental conditions. In the alpine regions of Norway, a project has been underway for 30 years that aims to change that. "We wired up some of the plants here and fitted them with so-called data loggers that record the measurements," explains Prof. Dr. Jörg Löffler from the Department of Geography at the University of Bonn. A pin-like sensor records the diameter of the trunk—minute by minute, 365 days a year, to an accuracy of less than a thousandth of a millimeter. At the same time, the researchers measure solar radiation, temperature in the root zone and just above the soil surface, and soil moisture.

Shrinkage against frost damage

In the current study, researchers analyzed nearly 500 million measurements from 40 plants between 2015 and 2019. "We mainly studied how the microclimate, that is, the conditions encountered by the individual plant, affects its growth," says Svenja Dobbert, who is doing her doctorate in Prof. Löffler's research group. This revealed a striking rhythm in both dwarf birch and crowberry. During the colder months, their trunk diameter shrank significantly in each case—a process that was reversed in the spring. However, it was not until late summer that the deficits were made up to such an extent that actual growth began.

"Due to low temperatures in the colder months, there is hardly any liquid water available for the plants," Dobbert says, explaining the finding. "They also reduce their trunk diameter by actively reducing the water content of their cells to avoid frost damage." Just how important this strategy is for both species to thrive is demonstrated by another observation—plants that shrank very little during the winter often showed little or no growth the following summer.

A second important finding is that he deciduous dwarf birches usually grew better after a mild winter. They therefore seem to generally benefit from warmer winters. With the evergreen crowberries it was the other way around. "In cold winters, there is usually less snowfall," Löffler says. "This could be an advantage for evergreen species because they can then keep up photosynthetic activity for longer and hence enter the growth phase earlier in the spring." It is therefore possible that  is causing an increasing spread of deciduous species and a concomitant displacement of evergreen species. Since the leaves of deciduous  have a comparatively large surface area (in contrast, those of evergreen species are usually needle-like), this effect could contribute to the further greening of arctic-alpine regions.

The microclimate is crucial

"However, our results also show that microclimatic conditions can be extremely different depending on the location," explains Löffler. For instance, at exposed, windy locations, snow cover tends to be very thin. The deciduous dwarf birch however requires a sufficiently thick insulating layer of snow in winter. It then has to use fewer resources to protect itself from frost. Without this warming blanket, the dwarf birch has a difficult time. The evergreen crowberry, in contrast, benefits from the extra sunlight during such snow-free periods. "Overall, our measurements prove that global climate data provide little valid evidence for local vegetation effects," emphasizes the geographer. "Studies like ours can potentially help us better model such complex effects and in turn better predict the effects of climate change on plant life."

As cargo shipments boom, ship strikes imperil whales in California and worldwide

The 100-foot-long whale dived and circled in the murky, dark waters of the Santa Barbara Channel, looking for a cloud of krill to scoop and catch inside her 20-foot-long jaws.

As the  began to resurface, whale scientist Brandon Southall was in a boat nearby, and he could feel his throat go dry. The whale was coming up right beneath a 200,000-ton transoceanic cargo ship, named the Maladarko, that was heading east from Hong Kong to its destination in Long Beach Harbor.

"We were plotting the two paths," said Southall, a researcher at the University of California, Santa Cruz and the president of an Aptos-based marine biology research firm. "It was a straight collision course."

With the increase of cargo and cruise boat traffic the last several decades, ships have become one of the deadliest threats  face in open oceans and coastal waters. Ship strikes are not thought to be a predominant cause of the West Coast die-off of gray whales since 2019, but they are a factor, and an increasing concern.

Between 2016 and 2020, at least 1,001 beached or dead whales were identified by the National Oceanic and Atmospheric Administration as having "injuries consistent with ship strikes," said Michael Milstein, a NOAA spokesman, describing an informal death-by-ship database the agency keeps.

Earlier this year, horrific photos of two  pinned to the hull of an Australian naval ship gained worldwide attention. The vessel had been conducting exercises in the waters near San Diego. The two bodies—one 65 feet long, the other just 25 feet—were draped over the hull.

"Anywhere you have major shipping routes and whales in the same place, you are going to see collisions," said Russell Leaper, an expert with the International Whaling Commission. "Unfortunately, that's the situation in many places."

While gray whales and humpbacks make up 70% of the reported strikes in the government's database, it's the endangered and threatened populations—such as North Atlantic right whales and the gargantuan Pacific blues—that concern scientists the most. For those whales, each death comes with a risk of population or species extinction.

Southall and colleagues, including John Calambokidis at Cascadia Research Collective, examined behavioral differences in whales during day and night.

They discovered that whales tend to hang out closer to the surface at night and for longer periods of time. This was especially true for blue whales, making them particularly vulnerable.

Scientists are unsure if the whales are resting during the night or feeding on  that move closer to the surface during nighttime hours—when krill-eating seabirds and other marine animals are sidelined. But these behaviors add to the complexities of avoiding collisions through mitigation measures—such as keeping an eye out for whales while on a moving vessel.

"Having a lookout isn't going to help," said Southall, president of Southall Environmental Associates.

What can make a difference, experts agree, is slowing down boat traffic—allowing whales not only the chance to flee, but possibly reducing the potential injury—and altering shipping lanes when whales are present.

Along the U.S. Atlantic Coast, mandatory speed restrictions during certain seasons have helped reduce right whale mortality. Conservation groups are asking the government to extend the regulations to boats smaller than 65 feet, as well as to expand the areas and times for these maximum speed limits.

Others are hoping to create protocols and communications systems that will allow boat captains, mariners and harbor masters to voluntarily reduce speeds and alter routes where whales are present—in real time.

Elliott Hazen, a researcher with NOAA's Southwest Fisheries Science Center in Monterey, has developed an app that works like Google Maps—except instead of navigating cars and harried drivers around Los Angeles, it helps boats avoid concentrations of whales.

Using data collected from satellites on ocean temperature, food distribution and currents, WhaleWatch can predict "whale hot spots" and warn vessels approaching such critical areas—giving boat captains a tool and an extra incentive to slow down, and possibly alter their route.

"It's predictive," said Hazen. "Here's where you are most likely to have concentration of whales."

Voluntary limits can only go so far. All researchers interviewed for this story said mandatory speed restrictions and route alterations are the best way to reduce whale mortality.

"One of the difficulties is that these cargo vessels, they have a small window of time to unload cargo," Hazen added. "If slow speeds are not mandatory, there may be little incentive for them to slow down."

Slower speeds also reduce the amount of fuel needed—making a voyage cheaper—and reduce the amount of carbon dioxide emitted into the atmosphere. "Slow speeds are a win for all," said Leaper.

In the case of the leviathan observed in the Santa Barbara Channel, Southall and his colleagues had previously attached temporary trackers, via suction cup, to the female blue whale. The monitors were part of a study they were conducting in 2014 on the behavioral responses of whales to military sonar.

After their experiment was over, they waited around for the trackers to drop off.

"They're expensive devices," said Southall, noting their $20,000 price tag and the need to retrieve them.

They kept a safe distance from this whale, whom they had known since 1987. She had been involved in capsizing a 23-foot private vessel off the coast of Shelter Island near San Diego in 2014.

Suddenly, as they waited, they saw her shoot from the depths straight toward the cargo vessel's trajectory.

"We watched, with our hands over our mouths, thinking, 'Oh, my God, are we gonna see a strike? Or a pool of blood?'" Southall said.

But then she stopped, mid-swim, and rolled to her side, just a few meters below the hull—presumably to eyeball the behemoth cruising over her.

For the next three minutes, she remained suspended below, only resurfacing after the cargo ship passed.

Humans aren't the only species whose metabolisms tend to slow down with age

If you feel like your metabolism just isn't what it used to be, no matter how many hours you spend in the gym, dolphins can relate.

A Duke University-led study finds that  burn calories at a lower rate as they get older, just like we do.

It's the first time scientists have measured an age-related metabolic slowdown in another large-bodied species besides humans, said first author Rebecca Rimbach, postdoctoral associate in evolutionary anthropology at Duke.

Rimbach has studied  and other aspects of physiology in animals ranging from mice to monkeys. But data on the inner workings of marine mammals such as  and whales have been scant, she says. That's because these ocean dwellers are notoriously difficult to recapture for repeat measurements.

"It can be very tricky to get the animal back when you need it," Rimbach said.

The researchers studied 10 bottlenose dolphins aged 10 to 45 living at two marine mammal facilities, Dolphin Research Center in Florida and Dolphin Quest in Hawaii.

To measure their average daily metabolic rate, the researchers used the "doubly labeled water method." Used to measure energy expenditure in humans since the 1980s, it's a method that involves getting the animals to drink a few ounces of water with naturally occurring "heavy" forms of hydrogen and oxygen added, and then tracking how long the animals take to flush them out.

Like humans present their arms for a , the dolphins at these facilities voluntarily raise their  out of the water so their caregivers can collect blood or urine as part of their regular checkups.

By analyzing the levels of heavy hydrogen and oxygen atoms in the blood or urine, the team was able to calculate how much carbon dioxide the dolphins produced each day, and thus how many calories they were burning as they went about their lives.

What they found surprised them.

The researchers expected dolphins to have revved-up metabolisms, since dolphins are warm-blooded just like people, and keeping warm requires more energy in water than in air.

But despite living in a watery world, they found that bottlenose dolphins burn 17% less energy per day than expected for a marine mammal of their size.

The scientists also noted some of the same signs of metabolic aging common in people. The oldest dolphins in the study, both in their 40s, used 22% to 49% fewer calories each day than expected for their body weight. And similar to humans, more of those calories ended up as fat rather than muscle. Dolphins in their 40s had body fat percentages that were 2.5 times higher than their under-20 counterparts.

It wasn't for lack of exercise, Rimbach said. Dolphins are amazing athletes, capable of leaping 10 feet into the air and swimming alongside power boats at speeds that would crush Michael Phelps.

The dolphins in the study were observed doing flips and spins, walking on their tails, jumping clear out of the water and going fast enough to leave a wake as often as six to 18 times an hour, and they remained active into their 40s.

But the metabolic pattern remained no matter what their activity level.

"And it's not because they're eating too much," either, Rimbach said. The researchers recorded how much herring and other fish the dolphins gobbled up, and they found that the older, fatter dolphins in the study actually ate fewer calories.

The researchers say such work could shed light on factors besides diet and lifestyle that underlie age-related weight gain in people.

"Further studies into this commonality we share with dolphins may help us understand why human metabolism slows as we age," said co-author Hannah Salomons, a graduate student in professor Brian Hare's lab at Duke.

"Having access to healthy dolphins under human care made this study possible," said co-author Austin Allen of the Duke University Marine Lab.

"We need more data, especially for younger dolphins, since we only looked at 10 individuals," Rimbach said. "But I think it's an exciting first study."Measuring metabolism in dolphins to calculate their caloric needs

Sex with robots: How should lawmakers respond?

Advancements in technology have resulted in the design of hyper–realistic, Wi-Fi–connected, programmable sex robots that can mimic human responses, but what do these developments mean for how we regulate interactions with "sexbots" in the future

In a new article in the The Bulletin: The Law Society of SA Journal, Flinders University law researchers analyzed the factors Australian lawmakers will have to consider when they weigh up whether it should be legal to import, own and use sexbots that resemble human adults.

Critics argue sex robots objectify women and increase the risk of sexual violence by desensitizing people to the way they treat living beings. Some robots can even be programmed to reject a user's sexual advances which mimic a refusal of consent, which is a key element of proving sexual offenses in Australia.

On the other hand, advocates claim benefits of sex robots can include empowering older Australians and people with disabilities, addressing sexual related anxiety, treating dysfunctions, promoting safe sex and creating a safe place for people who feel insecure about their sexual orientation.

A recent study into the therapeutic benefits of sex robots found the top three suggestions for the use of robots were for patients with: social anxiety (50%), people who do not have a partner but still want a sex life without resorting to fleeting acquaintances or prostitution (50%) and premature ejaculation (47%), according to sex therapists.

Madi McCarthy, now an Associate with law firm LK, recently completed her honors research into this topic with the College of Business, Government & Law. She says advancements in technology, coupled with increasing demand and , means Australian policymakers are likely to be confronted with calls for the regulation of sex robots in the near future.

"Legislators will have to balance competing and complex individual and public interests which pose new ethical, regulatory and  because of advancements in technology."

"While no Australian legislation currently regulates or prohibits sexual intercourse with robots, there are regulations on child-like sex dolls which have been addressed by the Commonwealth, South Australia and Queensland. These statutory provisions may guide any future laws on the use of adult sex robots but there are new factors which have to be considered."

Associate Professor Tania Leiman, Dean of Law at Flinders University, says sex robots challenge existing conceptions of how humans interact with emerging technologies in the most intimate way so regulators will have to balance , legal challenges and the real potential for technology to objectify and promote sexual violence.

"Even if sex robots are prohibited in Australia—it's likely that the courts may consider such offenses to be less objectively serious than sexual offenses against humans, and sentences may be more likely to fall at the lower end of the penalty range, even where maximum penalties are equivalent."

"For example, courts have consistently imposed lower end sentences for child-like sex doll offenses despite the maximum penalty range of 10 to 15 years."Design and market sexbots for older adults with disabilities, argues ethicist

Raccoon dogs pose a particular threat to ground-nesting birds in Northern Europe

Duck species in Finland are faring poorly, with more than half of the species listed as threatened to a varying degree, with alien predators as one of the suspected causes.

A new study proves the suspicions well-founded. In experiments carried out over three years by the University of Helsinki, Finland and Aarhus University, Denmark, wildlife cameras recorded an abundance of images of alien  predating artificial nests established by the researchers in Finland and Denmark.

More than 400  containing farmed mallard eggs were created, of which roughly 290 were located around southern Finland. The nests were built in natural duck nesting environments.

In Finland, raccoon dogs (Nyctereutes procyonoides) were more common  predators than red foxes, although in Denmark the situation was reversed, possibly reflecting the species' local relative abundance.

"The raccoon dog was the most common mammalian  in all of the environments studied in Finland. As expected, raccoon dogs destroyed nests on shorelines, but surprisingly often also in forests close to wetlands," says Postdoctoral Researcher Sari Holopainen from the Finnish Museum of Natural History Luomus, University of Helsinki.

Broken eggs attract mammalian predators

Wildlife cameras revealed that many nests were visited by more than one predator. Corvids were often the first to notice the nests. On occasion, they would break an egg in the nest, which would attract  to the spot. American minks and raccoon dogs often visited nests previously predated by others.

"Our research shows that predators cohabiting the same area can benefit from one another. Eggs broken by corvids offer a clue to mammalian predators, which, in turn, are a threat to both eggs and female ducks. In other words, the effect of a diverse predator community can exceed the sum of its species," Holopainen says.

The raccoon dog is a genuine habitat generalist

In terms of utilizing their environment, the raccoon dog was found in many ways to be more versatile than . The species was commonly observed on shorelines and shore forests, and it was flexible also with regard to agricultural and urban landscapes, whereas the presence of individual native mammal predators was restricted by habitat type. In addition, raccoon dogs were found to be an adaptive part of the predator community, as it was either the only species or a part of a community, rich in species that visited nests during the week-long observation period.

According to the researchers, the artificial nest experiments cannot directly prove that the raccoon dog has an effect on duck populations."What the results do show, however, is that the raccoon dog is a more common nest predator than native mammalian species, and that it is abundant in a range of duck nesting environments," Holopainen explains.

Several reasons for the decline of waterbird populations

In addition to alien predators, the decline of waterbird populations is caused by several factors, of which many are related to excessive eutrophication. However, the results of the artificial nest experiments help to understand the reasons for declining waterbird populations.

"The decline of many waterbird nesting populations, especially in eutrophic lakes, matches temporally the increasing abundance of raccoon dogs and American minks. This came out as we studied long-term changes in aquatic birdlife between the periods 1951–1970 and 1996–2015 using datasets collected in the Häme region by Pentti Linkola, the late fisherman," says Hannu Pöysä, a principal scientist at the Natural Resources Institute Finland.

The datasets provided a unique opportunity to assess, among other things, the role of alien predators in the decline of waterbird populations, since the data from 1951–1970 depicted a period of time when the raccoon dog and the American mink were few in number in Finnish nature.

The raccoon dog in Finland

The raccoon dog is a species indigenous to South-East Asia that was introduced as a fur animal in areas of the Soviet Union close to Europe from the 1920s onwards. From there, the species has spread to the continent, gaining ground thanks to its capacity to travel long distances. The longest migration observed using a GPS collar occurred in early 2016 when a raccoon dog made a 600-kilometer journey.

In Finland, the first raccoon dogs arrived as early as the 1930s. While the regional population is especially dense in southern Finland, the species is also able to live in Lapland. In fact, a relentless battle is being fought on the border between Finland and Sweden to prevent the species from spreading to the latter country.

In Finland, the number of culled raccoon dogs has grown steadily. In the early 1980s, the annual number of slain raccoon dogs was roughly 20,000. In the peak year of 2016, that number had increased tenfold. Indeed, the raccoon dog is Finland's second/third most common prey animal. Additionally, more than 20,000 raccoon  are estimated to be killed by road traffic each year.

In 2019, the EU added the raccoon dog to the list of harmful invasive alien species. One of the reasons for this was its impact on avian and amphibian species. The  dog can carry and spread a number of diseases, including rabies, echinococcosis, mange and trichinellosis.Raccoons and raccoon dogs are expected to expand their ranges in Europe
