There was little room for doubt about the reaction to the prime minister’s plans to scrap environmental regulations this weekend. “Make no mistake, we are angry. This government has today launched an attack on nature,” tweeted the RSPB, its most forceful political intervention in recent memory.

Liz Truss’s proposals to create investment zones, where green rules on nature protection would in effect be suspended, represented a step too far for some of Britain’s biggest environment charities. “As of today, from Cornwall to Cumbria, Norfolk to Nottingham, wildlife is facing one of the greatest threats it’s faced in decades,” the RSPB went on.

Swiftly after came the Wildlife Trust, representing another million members and also “incredibly angry … at the unprecedented attack on nature”, and the National Trust, with more than 5 million members.

For veteran green campaigners, the strength and speed of the intervention was striking. “It’s a very strong reaction,” said Tom Burke, co-founder of the green thinktank E3G, and a veteran adviser to governments. “The government cannot have been expecting this strong a reaction.”

The list of anti-green policies from a cabinet just a few weeks old is already extensive:

New investment zones threaten a regulatory vacuum where developers can ignore rules on water quality, species conservation and space for nature.

A bonfire of EU regulations could put paid to more than 500 rules protecting the natural world, from wildlife habitats to water quality.

Fracking has been given the green light, and more than 100 new licences for oil and gas drilling will be granted in the North Sea.

A nod to onshore wind was the only low-carbon measure of any note in the “mini-budget” on Friday.

The environmental land management contracts for farmers are being reviewed. Championed as a “Brexit dividend”, Elms were meant to reward farmers for protecting nature, offering “public money for providing public goods”. Scrapping them would return the UK to subsidising intensive agricultural production at the expense of nature.

There has also been little engagement from the cabinet with key stakeholders, including green groups and farming leaders apart from the National Farmers’ Union, a supporter of scrapping Elms. Ranil Jayawardena, the secretary of state for environment, food and rural affairs, has not yet met with green groups and stakeholders, a failure that Shaun Spiers, the executive director of the Green Alliance thinktank, described as “unprecedented”.

The government is still nominally committed to the UK’s legally binding net zero emissions target, and Truss had made senior appointments – including the levelling up secretary, Simon Clarke, and minister Graham Stuart – with green credentials. But green Tories are increasingly concerned.

Ben Goldsmith, the investor and chair of the Conservative Environment Network, said: “There are worrying rumours that the new Conservative ministerial team at Defra are toying with the idea of delaying or derailing the brilliant, groundbreaking new environmental land management scheme, which will link all taxpayer-funded farm payments to the stewardship and restoration of soil and nature. Losing this would of course be a disastrous backwards step, so we must hope that they are only rumours.”

Contrast this with the scene in Liverpool, where Labour opened its party conference this week with the prospect of a clean power generation system by 2030, green public procurement, a low-carbon industrial revolution, and the promise to make Britain “fairer and greener”.

On environmental policy, from fracking to farming, new “clear green water” appears to be opening up between the UK’s two main parties. Spiers warned: “We have been very proud in this country of keeping environmental issues mainstream. This should not be a culture war issue. Conservative voters in middle England don’t want to trash the countryside.”

Despite the furious reaction from mainstream green organisations, which has rattled some backbench and green Tory MPs, Truss seems prepared to double down on her liberalisation agenda even if that means antagonising them further. The Guardian understands that a mooted mollifying statement from No 10, aimed at reassuring voters and MPs in marginal seats, was ditched.

Veteran green experts warned that Truss had misjudged the public mood in her haste to forge a new rightwing radical position. “There is a giant gulf between where Liz Truss thinks the British people are, and where the British people really are,” said Burke.

But he added that green campaigners should not assume that Labour would ride to their rescue. “What parties say in opposition is not always what they do in government. There will need to be firm commitments from Labour that they will restore what the Tories are destroying.”

Doug Parr, policy director of Greenpeace, called on Truss to change course. “[Her] government has launched an indiscriminate attack on environmental rules ignoring both their own manifesto commitments and very strong public concerns about nature,” he warned.


Government poised to scrap nature ‘Brexit bonus’ for farmers

“Voters understand that we need tougher laws to protect the living world. They see water firms getting away with pumping tonnes of raw sewage into our rivers and seas while raking in huge profits, supermarkets flooding our homes with throwaway plastic, and destructive fishing plundering our marine protected areas with impunity. They can tell the difference between so-called red tape and vital rules to stop pollution and environmental harm.”

For Labour, he added, the challenge was to match a strong slate of low-carbon policies with new proposals on nature and the countryside. “This should be a political open goal for Labour. They should get their act together, seize the opportunity and make their nature protection policy as strong as their climate ones.”


Farmers threaten to quit NFU as leader backs scrapping of nature subsidies

Farmers are threatening to quit the National Farmers’ Union after its leader said she supported the UK government’s apparent move to scrap post-Brexit nature subsidies.

This weekend, the Observer revealed that the government was poised to abandon the “Brexit bonus”, which would have paid farmers and landowners to enhance nature, in what wildlife groups have described as an “all-out attack” on the environment.

Instead of the environmental land management scheme (Elms), Department for Environment, Food and Rural Affairs (Defra) sources disclosed, they are considering paying landowners a yearly set sum for each acre of land they own, which would be similar to the much-maligned EU basic payments scheme of the common agricultural policy.

Minette Batters, the president of the NFU, said she welcomed the departure from Elms. “My absolute priority is ensuring that farmers can continue to produce the nation’s food – so I do support maintaining direct payments in order to build a scheme that really will deliver for food production and the environment,” she said.

She later doubled down on this point, telling the BBC that she believed private money should be used to pay farmers for wildlife recovery, rather than public funds. She said: “We have got literally billions and billions of pounds in green finance that is looking to invest in wild environments. We should be making the private sector work effectively.”

Prominent members of the NFU have spoken to the Guardian, saying they were minded to quit if the leadership failed to clarify its position and support payments for environmental protections.

Jake Freestone, a regenerative farmer and Worcestershire county chairman for the union, has won awards for his soil quality after practicing nature-friendly farming. While he said he is not yet at the point of quitting, he appeared disappointed with the NFU’s apparent views on Elms.

“We do need to focus on the environment as well as food production and what does worry me is if we are going to throw out a lot of environmental protection on the basis of food security. But we are quite happily farming productively here and also providing good environmental protection – if you don’t have wildlife and pollinators and farmland birds, what do you have?” he said.

“The challenge we have is the NFU have a lot of diversified members with a lot of different interests.”

Martin Lines, the chair of the Nature Friendly Farming Network (NFFN), said many of his fellow farmers were leaving the NFU over its perceived anti-nature stance.

“I know of lots of NFU members who are very unhappy or have already left,” he said. “Unfortunately many farmers are members because they feel there hasn’t been any other farming body in the past that is a voice for farming. I know many farmers who are leaving the NFU and joining organisations like the Country Land and Business Association (CLA), NFFN and others, as the NFU doesn’t represent their views or voice.

“Many farmers are starting to realise the NFU does not represent or champion their voice or farming system.”

Mark Tufnell, the chair of the CLA, which represents 30,000 landowners, said he hoped the government would stick with Elms. He said: “There is concern that there might be a change in direction, it’s harsh to come in at a very early stage and say it isn’t working as it hasn’t been given a chance.”

On the NFU’s policy, he said: “You would have to ask the NFU. We have actively stated since about 2017 that we have always felt it is very difficult to justify a flat-rate payment to farmers and landowners just for the sake of owning land. The benefit of Elms is the more public goods you provide, the more you get paid, and you can stack the amounts you do in the public scheme with the private element.”

The NFU has been lobbied by some influential voices who are against Elms. Celebrities including the TV presenter Jeremy Clarkson, former Undertones singer Feargal Sharkey and former cricketers Ian Botham and David Gower have written to the government asking them to scrap environmental regulations.

Writing as “rural voices” who do “real work” that includes “cultivating the soil, looking after sick animals and bringing in the harvest”, they said environmental regulations on farmers “seek to appease the insatiable demands of a few self-righteous campaigners”.

On Monday, Batters said: “We’re pleased the government is reviewing the framework for future farming regulation to help ensure farm businesses are supported through the current economic challenges and can make progressive decisions to boost growth and farming’s contribution to the nation.

“The NFU has always supported the ‘public money for public goods’ policy but we have called for a delay as the scheme was not fit for purpose and ready to roll out in its current form.”

This dash for growth represents the death of green Toryism

Boris Johnson was far more eco-conscious than recent Conservative predecessors. But this mini-budget is a reversion to type

Kwasi Kwarteng: no mention of net zero.

The dash for growth by Kwasi Kwarteng means unshackling City bankers and property developers from the taxes and regulations that prevent them from paving over what’s left of Britain’s green and pleasant land.

The humble concrete mixer will be elevated to exalted status. There will be more executive homes built on greenfield sites. More distribution sheds dotted along busy A-roads. And more urban renewal of the kind that involves tearing down buildings in a plume of dust and carbon emissions to replace them with something not much better, at least not in environmental terms.

At no point in the chancellor’s speech on Friday did he mention the need to reach net zero, or how his plans would help our ailing planet while doling out billions of pounds in tax cuts to richer households and businesses.

Boris Johnson’s administration at least put in place plans for achieving net zero, and Michael Gove considered ways of reversing 70 or more years of severe biodiversity loss.

As Fiona Harvey has documented in the Guardian, Johnson’s premiership brought “more major environmental legislation and arguably greater progress on tackling the climate and nature crises than either of his Conservative predecessors in the past decade”. That’s a low bar when David Cameron and his chancellor George Osborne did their best to kick almost all green initiatives into the long grass, but Johnson did put in place the Agriculture Act, the Fisheries Act, and the Environment Act, coupled with plans to phase out petrol and diesel cars, create a boom in offshore wind, and protect a third of the UK’s land and seas.

Johnson’s legacy, though, is largely rhetoric and very little action. That’s the message from those who attended committee meetings to put meat on the bones of his “10-point plan for a green industrial revolution” only to find themselves in nothing more than a talking shop. One member of Johnson’s Green Jobs Delivery Group, who preferred to remain nameless, said that if the discussion had ever broadened beyond how many millions of trees could be planted in the UK, a strategy might have emerged.

It didn’t seem to matter that senior executives from Siemens, BMW and E.ON were sitting around the table with the head of England’s further education colleges and representatives of the major industrial lobby groups – the discussion still didn’t go anywhere.

By the time Liz Truss sacked the minister in charge who chaired the delivery group, Greg Hands – whose green credentials were burnished when he resigned from a ministerial post in 2018 over plans to expand Heathrow – the group appears to have achieved nothing but an agenda for the next meeting.

Tree planting is indeed an important issue facing urban landscapes, as well as a countryside plagued by drought. Economically, there is also a good reason to talk about the subject: the UK imports 80% of the wood needed for items ranging from toilet paper to construction timber when well-managed forests could fill the gap.

A junior climate minister – well-meaning and well-connected though he is – is clearly only window dressing in a government that wants to bring back fracking


Still, it was one initiative among many, and a change that was poised to spread across major industrial and commercial sectors could not happen while the political focus lay elsewhere.

Green Tories want us to think the party still cares after Truss appointed Graham Stuart as junior minister for climate change. Stuart was one of the leading voices urging Theresa May to enshrine the net zero target in law. He has also been involved in the Globe group of legislators who push for laws mandating climate action to be passed by national parliaments.

But a junior minister – well-meaning and well-connected though he is – is clearly only window dressing in a government that wants to bring back fracking, produce more North Sea oil and rip up planning laws.

Maybe Truss will reveal herself as a champion of green policies: she spoke several times about the need to act on the climate crisis during her leadership campaign and has committed herself to attending Cop27 in Egypt and the 15th biodiversity Cop in Canada.

Except that the new prime minister, as environment secretary, cut subsidies to solar farms. She has also shown little appetite for accelerating an upgrade of the electricity grid to accommodate more renewable energy providers, or supporting major manufacturing industries as they transition to net zero.

Without a prime minister and cabinet that understands the risk of a dash for growth – one that generates yet more carbon – it will fall to fracking protesters and nimbys to prevent the UK going backwards. They will need to be on the streets in force to block what in most cases will be disastrous and unjustified initiatives.

Meteorologist reacts to Fiona: 'Like nothing I've ever seen'
'You see this stuff on the news in Puerto Rico'

Updated Sept. 26, 2022 

NTV News' Chief Meteorologist Eddie Sheerr offered a grim account of the impact post-tropical storm Fiona had on the southern part of Newfoundland and Labrador.

"The power of the ocean was just relentless." Sheerr said Sunday. "The toll that this storm surge took on the southern part of this island is like nothing I've ever seen."

According to the meteorologist, when Fiona hit Port aux Basques, the area became "ground zero" for a storm surge what was made worse because of "tidal run up" a phenomenon that causes low tides and high tides to get successively higher.

"What transpired was significantly worse than I even thought it would be," Sheerr said on Sunday. "The reason for that was the water levels were just so high."

Fiona descended on Port aux Basques on Saturday as a post-tropical storm that,in addition to the catastrophic storm surge, was also churning out 130-kilometre-per-hour wind gusts.

Mayor Brian Button said the damage to the town of 4,000 has been devastating and the cleanup won't be quick.

"This is going to take days, could take weeks, could take months in some places.".

N.S. family thankful after four-year-old found safe in woods in aftermath of Fiona

Grady MacKinnon wandered off while his family was outside cleaning up after the storm

Anjuli Patil · CBC · Posted: Sep 26, 2022 



Boy found safe after spending night in N.S. woods in wake of storm
'The day after a hurricane with fallen trees and tons of water down and these are unforgiving circumstances. Anything could have happened.'

Four-year-old Grady MacKinnon is safe and sound at home with his family.

On Saturday, after post-tropical storm Fiona barrelled through Nova Scotia's Pictou County, he wandered off into the woods. His parents said they were outside their home in rural Springville, N.S., picking up after the storm with Grady.

"You see these stories on the news, and you think, 'Oh these parents weren't watching their kids, they weren't out with their kids.' And we were out with them and it was a minute we didn't have our eyes on him," Gillian MacKinnon, Grady's mother, told CBC News.

"A minute led to 15 hours of just pure panic and torture."

Gillian said Grady went missing around 5 p.m. on Saturday.

"It's 10 acres of really thick wooded old trees and we searched for a good 20 minutes and we couldn't hear him, we couldn't see him," she said. 

Gillian and her husband, Adam, knew something was wrong and went to a neighbour's house and called 911. By 5:45 p.m., she said there was a "full-blown search."

"He's four and he's in the woods the day after a hurricane with fallen trees and tons of water down and these are unforgiving circumstances. Anything could have happened," Gillian said.

"You're in the woods for the whole night just praying that you'll come across something — good or bad — like you just want to know where he is. There's just no words to describe as a parent the guilt you feel. I wouldn't wish that on anybody."

Grady was found on Sunday morning by his grandfather, Gary Murray, and local paramedic Mary Kenny. The family said Kenny went with the grandfather to make sure he was safe too.

Gillian said her father, who is almost 70, is a hero.

"The two of them trucked through the most awful terrain to find him and I find it hard to believe [Grady] made it through that, let alone they made it through that and they just bought him home," Gillian said.

Adam said he was told Grady was "happy" when he was found.

"He was strolling through the woods after spending the night there in the cold and pitch black, just kind of strolling along," Adam said.

"... [Grady is] strong. He must get that from his mother's side, he doesn't get that from me I can tell you that right now."

Gillian said police estimated Grady had wandered about 10 to 15 kilometres in the woods.

The family said they are grateful to the community members who dropped everything to help search for Grady, even after the storm had knocked out power and water for nearly everyone. 

Adam described the relief he felt when he heard one of Gillian's friends calling his name to tell him Grady had been found.

"[Gillian and I] both did a good job of holding it together until we found him. Once we knew he was home safe, that's when we fell apart. He was home in the tub by the time I got home," Adam said.

Wild horses on Sable Island appear safe after island struck by Fiona


THEY HAVE BEEN HERE SINCE THE MAYFLOWER LANDED

The herd of wild horses inhabiting an isolated island that was directly in the path of post-tropical storm Fiona appear to have come through the extreme weather safely.

Sable Island, a small island around 300km southeast of Halifax, Nova Scotia, is a National Park Reserve, staffed by a handful of Parks Canada employees year round.

Around 500 wild horses have roamed the island freely since the 18th century — but as there is little natural protection for the horses on an island predominantly made up of dunes and grasslands, officials were worried that the storm could pose a threat to the horses.

On Sunday, Sable Island Institute (SIL) posted an update to their Facebook page, stating that they had heard from an employee on the island around 4 p.m. local time on Saturday.

RELATED STORIES What will happen to the wild horses on Sable Island impacted by Fiona?

“Everyone is fine, but there is a lot of wind damage and debris around the station to clean up, as well as some erosion that will prevent vehicles from checking the beaches for a while,” the post read. “She said that by late morning [Saturday], horses had emerged from sheltered areas and were grazing, grooming, and engaged in their usual activities.”

Sable Island Institute is a not-for-profit organization that supports programs on the island. One of their employees, as well as three Parks Canada personnel, were on the island during the storm, according to the Facebook post.

“The horses are pretty used to storms, they find shelter from the wind and blowing sand in the lee of dunes - there are plenty of hollows and high dune slopes in inland areas, and depending on the wind direction, the horses also huddle on the beach at the base of the dunes,” the post explained.

Personnel had apparently taken down their Starlink dish ahead of the storm to protect it, but were able to get in contact with the mainland after putting it back up when the winds had died down.

The horses are protected as wildlife by Parks Canada, along with a wide range of wild birds. Although the island does have tours for tourists, it is forbidden for anyone to approach or disturb the horses. Scheduled tours were cancelled ahead of the storm.

SIL explained in a comment on the post that although the island itself is very low, it didn’t become submerged during the storm because the large waves observed near some provinces couldn’t form there.

“Because of the gradual slope to the beaches, the waves would not be 100 ft high when they reach the shoreline.”

P.E.I.'s iconic Teacup Rock is gone after post-tropical storm Fiona

'It's definitely a sad landmark to lose'

These shots from Marg Chisholm-Ramsay show Teacup Rock and the remnants of the rock on Sunday. (Submitted by Marg Chisholm-Ramsay)

P.E.I.'s iconic Teacup Rock is gone after post-tropical storm Fiona walloped the Island for more than 12 hours over the weekend, leaving widespread destruction and tens of thousands without power.

The landmark at Thunder Cove Beach was one of the Island's most photographed rock formations — and it gained popularity in recent years thanks to social media.

Dale Paynter snapped a photo of what's left of the rock on Sunday.

"I can remember the Teacup before it was called 'the Teacup,'" he told CBC News.

"It was a larger rock with three legs, and before that it was probably attached to the cliff. I was happy to see it spend its final years as a 'rock star.'"

Marg Chisholm-Ramsay also snapped photos of the void where Teacup Rock used to be on Sunday.

"I've seen many great things in my travels: the Great Wall of China ... the Great Pyramid of Giza, and the Lion of Lucerne but to me the Thunder Cove Teacup was more magnificent because she formed herself from nature," she said.

"The Teacup has seen baby announcements, gender reveals, family pictures, marriage proposals and even ashes were spread near the Teacup — all significant life events. 

"The Teacup is ours (Islanders), but it meant a lot to others too."

'A sad landmark to lose'

Debbie Murray also headed down to the beach on Sunday to see the damage for herself.

"It is very saddening to know that many people will never get to experience it," she said. "They will not get to experience the 'wow' factor of coming around the rocks through the water to see the Teacup. Our shores have such beauty and the sea is to thank for most of it ... Goodbye forever Teacup Rock, thank you for all the memories."

Katie McCrossin's family has cottages on the north shore of P.E.I. with a view of the rock, where her parents confirmed that the rock formation is no longer.

Dale Paynter shared this photo of Teacup Rock in its heyday on the left, and a shot of what's left of the iconic landmark taken on Sunday. (Submitted by Dale Paynter)

"My parents have confirmed that Teacup Rock was taken by Hurricane Fiona," she said. "It's definitely a sad landmark to lose … It's sad for many. I think there's been lots of memories made around that rock and around that area of P.E.I. and the beach."

McCrossin spent her childhood summers on the beach, and says the loss isn't a surprise for those who live in the area.

"My childhood was playing down there, catching crabs, and swimming on those rocks. And now my three kids were doing the same. It's been around for generations. But so have other rocks, and they've disappeared and new ones have come … The coastline is forever changing," she said.

'It’s definitely a sad landmark to lose,' says Katie McCrossin, who spent childhood summers on the beach. (Jane Robertson/CBC)

"Every year, every fall, we think, 'Oh it's gonna be gone this winter.' I guess it took it a little sooner — you always think it's gonna be the ice that takes it. But Hurricane Fiona was quite the storm."

Chrysalis: Saturn’s Ancient, Missing Moon

By JENNIFER CHU, 
MASSACHUSETTS INSTITUTE OF TECHNOLOGY
 SEPTEMBER 25, 2022


Scientists propose a lost moon of Saturn, which they call Chrysalis, pulled on the planet until it ripped apart, forming rings and contributing to Saturn’s tilt. This natural color view of Saturn was created by combining six images captured by NASA’s Cassini spacecraft on May 6, 2012. It features Saturn’s huge moon Titan, which is larger than the planet Mercury. Below Titan are the shadows cast by Saturn’s rings.

Saturn’s Rings and Tilt Could Be the Product of an Ancient, Missing Moon

According to a new study, a “grazing encounter” may have smashed the moon to bits to form Saturn’s rings.

Swirling around the planet’s equator, the rings of Saturn are an obvious indicator that the planet is spinning at a tilt. The belted gas giant rotates at a 26.7-degree angle relative to the plane in which it orbits the sun. Because Saturn’s tilt precesses, like a spinning top, at nearly the same rate as the orbit of its neighbor Neptune, astronomers have long suspected that this tilt comes from gravitational interactions with Neptune.

Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Saturn, a gas giant like Jupiter, is a massive ball made mostly of hydrogen and helium. While it is not the only planet to have rings, none are as magnificent or as complex as Saturn’s. Saturn also has dozens of moons. It is named for the Roman god of agriculture and wealth, who was also the father of Jupiter.

However, a new modeling study by astronomers at MIT and elsewhere has found that, while the two planets may have once been in sync, Saturn has since escaped Neptune’s pull. What was responsible for this planetary realignment? The research team has one meticulously tested hypothesis: a missing moon. Their study was published in the journal Science on September 15.

In the study, the team proposes that Saturn, which today hosts 83 moons, once harbored at least one more, an extra satellite that they named Chrysalis. Together with its siblings, the astronomers suggest, Chrysalis orbited Saturn for several billion years, pulling and tugging on the planet in a way that kept its tilt, or “obliquity,” in resonance with Neptune.

However, the team estimates that around 160 million years ago, Chrysalis became unstable and came too close to its planet in a grazing encounter that pulled the satellite apart. The loss of the moon was sufficient to remove Saturn from Neptune’s grasp and leave it with the present-day tilt.

Furthermore, the astronomers surmise, while most of Chrysalis’ shattered body may have made impact with Saturn, a fraction of its fragments could have remained suspended in orbit, eventually breaking into small icy chunks to form the planet’s signature rings.

Chrysalis, the missing satellite, therefore, could explain two longstanding mysteries: Saturn’s present-day tilt and the age of its rings, which were previously estimated to be about 100 million years old — much younger than the planet itself.

“Just like a butterfly’s chrysalis, this satellite was long dormant and suddenly became active, and the rings emerged,” says Jack Wisdom. He is lead author of the new study and a professor of planetary sciences at MIT.

The study’s co-authors include Rola Dbouk at MIT, Burkhard Militzer of the University of California at Berkeley, William Hubbard at the University of Arizona, Francis Nimmo and Brynna Downey of the University of California at Santa Cruz, and Richard French of Wellesley College.

A moment of progress

In the early 2000s, scientists put forward the idea that Saturn’s tilted axis is a result of the planet being trapped in a resonance, or gravitational association, with Neptune. However, observations taken by NASA’s Cassini spacecraft, which orbited Saturn from 2004 to 2017, put a new twist on the problem. Scientists discovered that Titan, Saturn’s largest satellite, was migrating away from Saturn at a faster clip than expected, at a rate of about 11 centimeters per year. Titan’s fast migration, and its gravitational pull, led scientists to conclude that the moon was likely responsible for tilting and keeping Saturn in resonance with Neptune.

Yet this explanation hinges on one major unknown factor: Saturn’s moment of inertia, which is how mass is distributed in the planet’s interior. Saturn’s tilt could behave differently, depending on whether matter is more concentrated at its core or toward the surface.

“To make progress on the problem, we had to determine the moment of inertia of Saturn,” Wisdom says.

The lost element

In their new study, Wisdom and his colleagues looked to pin down Saturn’s moment of inertia using some of the last observations taken by Cassini in its “Grand Finale,” a phase of the mission during which the spacecraft made an extremely close approach to precisely map the gravitational field around the entire planet. The gravitational field can be used to determine the distribution of mass in the planet.

Wisdom and his colleagues modeled the interior of Saturn and identified a distribution of mass that matched the gravitational field that Cassini observed. Surprisingly, they discovered that this newly identified moment of inertia placed Saturn close to, but just outside the resonance with Neptune. The planets may have once been in sync, but are no longer.

“Then we went hunting for ways of getting Saturn out of Neptune’s resonance,” Wisdom says.

First, the team carried out simulations to evolve the orbital dynamics of Saturn and its moons backward in time, to see whether any natural instabilities among the existing satellites could have influenced the planet’s tilt. This search came up empty.

So, the researchers reexamined the mathematical equations that describe a planet’s precession, which is how a planet’s axis of rotation changes over time. One term in this equation has contributions from all the satellites. The team reasoned that if one satellite were removed from this sum, it could affect the planet’s precession.

Saturn Facts 
Planet Type: Gas giant
Radius: 36,183.7 miles / 58,232 kilometers
Day: 10.7 hours
Year: 29 Earth years
Moons: 63 confirmed and named / 20 provisional
Axis Tilt: 26.73 degrees


The question was, how massive would that satellite have to be, and what dynamics would it have to undergo to take Saturn out of Neptune’s resonance?

Simulations were run by Wisdom and his colleagues to determine the properties of a satellite, such as its mass and orbital radius, and the orbital dynamics that would be required to knock Saturn out of the resonance.

From their results, they conclude that Saturn’s present tilt is the result of the resonance with Neptune and that the loss of the satellite, Chrysalis, which was about the size of Saturn’s third-largest moon, Iapetus, allowed it to escape the resonance.

Sometime between 200 and 100 million years ago, Chrysalis entered a chaotic orbital zone, experienced a number of close encounters with Iapetus and Titan, and eventually came too close to Saturn, in a grazing encounter that ripped the satellite to bits, leaving a small fraction to circle the planet as a debris-strewn ring.

The loss of Chrysalis, they found, not only explains Saturn’s precession, and its present-day tilt, but it also explains the late formation of its spectacular rings.

“It’s a pretty good story, but like any other result, it will have to be examined by others,” Wisdom says. “But it seems that this lost satellite was just a chrysalis, waiting to have its instability.”

'We have impact!' NASA slams spacecraft into asteroid in unprecedented test

1st attempt to shift the position of a natural object in space

A NASA spacecraft slammed into an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth.

The galactic grand slam happened 11.3 million kilometres away, with the spacecraft — the Double Asteroid Redirection Test (DART) — plowing into the rock at 22,500 km/h. Scientists expected the impact to carve out a crater, hurl streams of rocks and dirt into space and, most importantly, alter the asteroid's orbit.

"We have impact!" Mission Control's Elena Adams announced, jumping up and down and thrusting her arms skyward.

Telescopes around the world and in space aimed at the same point in the sky to capture the spectacle. Though the impact was immediately obvious — DART's radio signal abruptly ceased — it will be days or even weeks to determine how much the asteroid's path was changed.

"Now is when the science starts," said NASA's Lori Glaze, planetary science division director. "Now we're going to see for real how effective we were."

The $325-million US mission was the first attempt to shift the position of an asteroid or any other natural object in space.

"What an amazing thing. We've never had that capability before," Glaze added.

WATCH | DART's impact with asteroid:

Orbiting sun for eons

Earlier in the day, NASA Administrator Bill Nelson reminded people via Twitter that, "No, this is not a movie plot." He added in a prerecorded video: "We've all seen it on movies like Armageddon, but the real-life stakes are high."

Monday's target was a 160-metre asteroid named Dimorphos. It's actually a moonlet of Didymos (Greek for "twin"), a fast-spinning asteroid five times bigger that flung off the material that formed the junior partner.

The pair have been orbiting the sun for eons without threatening Earth, making them ideal save-the-world test candidates.

Launched last November, the vending machine-size DART navigated to its target using new technology developed by Johns Hopkins University's Applied Physics Laboratory, the spacecraft builder and mission manager.

DART's on-board camera, a key part of this smart navigation system, caught sight of Dimorphos barely an hour before impact.

"Woo hoo," exclaimed Adams at the time. "We're seeing Dimorphos, so wonderful, wonderful."

Days or months before new orbit confirmed

With an image beaming back to Earth every second, Adams and other ground controllers in Laurel, Md., watched with growing excitement as Dimorphos loomed larger and larger in the field of view alongside its bigger companion. Within minutes, Dimorphos was alone in the pictures; it looked like a giant grey lemon, but with boulders and rubble on the surface. The last image froze on the screen as the radio transmission ended.

Flight controllers cheered, hugged one another and exchanged high fives.

A mini satellite followed a few minutes behind to take photos of the impact; the Italian Cubesat was released from DART two weeks ago.

Scientists insisted DART would not shatter Dimorphos. The spacecraft packed a scant 570 kilograms, compared with the asteroid's five billion kilograms. But that should be plenty to shrink its 11-hour, 55-minute orbit around Didymos.

The impact should pare 10 minutes off that, but telescopes will need anywhere from a few days to nearly a month to verify the new orbit. The anticipated orbital shift of one per cent might not sound like much, scientists noted. But they stressed it would amount to a significant change over years.

Planetary defence experts prefer nudging a threatening asteroid or comet out of the way, given enough lead time, rather than blowing it up and creating multiple pieces that could rain down on Earth.

Multiple impactors might be needed for big space rocks or a combination of impactors and so-called gravity tractors, not-yet-invented devices that would use their own gravity to pull an asteroid into a safer orbit.

"The dinosaurs didn't have a space program to help them know what was coming, but we do," NASA's senior climate adviser Katherine Calvin said, referring to the mass extinction 66 million years ago believed to have been caused by a major asteroid impact, volcanic eruptions or both.

Countless space rocks

The non-profit B612 Foundation, dedicated to protecting Earth from asteroid strikes, has been pushing for impact tests like DART since its founding by astronauts and physicists 20 years ago. Monday's feat aside, the world must do a better job of identifying the countless space rocks lurking out there, warned the foundation's executive director, Ed Lu, a former astronaut.

Significantly fewer than half of the estimated 25,000 near-Earth objects in the deadly 140-metre range have been discovered, according to NASA. And fewer than one per cent of the millions of smaller asteroids, capable of widespread injuries, are known.

The Vera Rubin Observatory, nearing completion in Chile by the National Science Foundation and U.S. Energy Department, promises to revolutionize the field of asteroid discovery, Lu said.

Finding and tracking asteroids, "That's still the name of the game here. That's the thing that has to happen in order to protect the Earth," he said.



Residents, businesses take aim at Edmonton's approach to homeless camps

City says it's taken down 1,370 camps so far this year, 

complaints up 25 per cent from 2021

The City of Edmonton's approach to dealing with homeless encampments this year is pushing social disorder to new neighbourhoods and new levels, business leaders and residents say. 

The city's encampment response teams have taken down more than 1,370 homeless camps so far this season, a spokesperson told CBC News last week. 

In 2021, the city dismantled 1,780 for the entire year.

The city said public complaints about encampments have gone up 25 per cent. In 2021, the city had 6,693 complaints and it's received 5,693 complaints so far this year. 

Michael Shandro, general manager of the Best Western Plus City Centre Inn on 113th Avenue and 109th Street, said every day, his employees have issues with people who aren't guests. 

"Daily, I'm getting reports of them being either verbally or physically assaulted," he said of his staff. "People refusing to leave."

Shandro said his staff have discovered people who aren't guests of the hotel drinking in the hallway, and others setting up camps along the side of the inn. 

"It used to be like every week or two we'd have an incident, we'd talk about it, we'd deal with it and that was it," he said. "My staff are getting jaded."

Ellie Sasseville, executive director of the Kingsway District Association, said they've noticed more camps in the area, one recently behind the building on 118th Avenue.

She said they paid $700 to have cleaners haul away trash and debris left by campers last week and businesses shouldn't have to do that. 

Refocusing patrols

In May, police and city peace officers started refocusing patrols in Chinatown, downtown and on Edmonton transit, after two men were killed in Chinatown. 

Since then, smaller camps have appeared beyond the inner core in places like Kingsway, along 107th Avenue and Whyte Avenue. 

Mayor Amarjeet Sohi said he's hearing concerns from business leaders and residents.

"Problems are spilling over into neighbouring communities," Sohi told CBC News. 

Sohi said he hopes a fully staffed Healthy Streets Operations Centre, set up in Chinatown, will allow hot-spot policing and enforcement. 

"That will help neighbouring communities as well, so I hope that will work," he said. "But we know that enforcement is a Band-Aid solution." 

Tim Pasma, manager of homeless programs with Hope Mission, also said clamping down on camps in the inner city means pushing people out. 

However, he thinks the increased police presence in Chinatown, where there's typically a lot of social disorder, has helped make the neighbourhood safer. 

"There's been a lot of crime, there's been a lot of pain suffered by the community, you know, from a lot of the encampments," Pasma said in an interview last week. 

"We do feel like it's safer," he said. "There's still a lot of issues that need to be addressed. So it's really, it's a Band-Aid solution. I think everybody knows that, but it's at least one step in the right direction."

Taking down tents 

The number of people identifying as homeless doubled from the beginning of the COVID-19 pandemic. 

More than 2,750 people have no permanent home and almost 1,300 people are sleeping outside or in shelters on any given night, the city and housing agency Homeward Trust report. 

The city developed a new encampment strategy last year, with response teams made up of social agency workers, police and city peace officers clean-up crews.

Last Thursday, the city's encampment response teams dismantled a camp of at least 20 tents at 96th Street and 106th Avenue.

Barb Laidlaw, a resident living across the street for 15 years, said she complained about the social disorder more than two weeks earlier.

"This is the worst year that it's been for all these camps," Laidlaw said. "It's very exhausting. We're always filing 311 complaints about drug use and litter and stolen property." 

A day later, tents appeared again on the same site, CBC News found.

The city's new approach to dealing with camps stems from preventing a huge encampment like Camp Pekiwewin in the Rossdale neighbourhood and the Peace Camp in Old Strathcona in summer and fall 2020. 

Pasma said large encampments are a safety risk to the general public, first responders and people living in the tent city, where there's exploitation, drug use and crime. 

"A lot of the effort has been placed on making sure that these encampments don't grow exponentially to a point where we can't control it anymore," Pasma said. 

Winter plan

City, social, agencies and the province are still working on a plan to create more winter shelter spaces but they don't know where that will be. 

Last winter, the Spectrum building at the Northlands property on 118th Avenue and Commonwealth Stadium were used as temporary emergency shelters, but the city said neither site is likely to be used this year.

In 2020, the Edmonton Convention Centre was the designated 24/7 shelter during the first winter of the COVID-19 pandemic. 

"I think there is an urgency to it," Pasma said. "I think everybody that works in the sector and from a funding level is aware of the urgency."

It's a challenge to find temporary spaces, staff, and the logistics of setting up and operating an emergency shelter, Pasma noted. 

"As soon as we can have something in place, the better." 

Sohi said he's hopeful the province will come through with funding for winter shelter spaces and then longer-term housing solutions for more of Edmonton's homeless population.
