NOTHING IS TRUE, EVERYTHING IS PERMITTED
New Physics Experiment Indicates There's No Objective Reality

Turns out, reality is at odds with itself.

Someone once said: "The world is all that is the case."

But, is it?

Researchers performing a long-awaited experiment created different realities that are irreconcilable, proving that objective facts can be made to exhibit properties that cannot cohere, according to a recent study shared on a preprint server.

Sound confusing? You're not alone in thinking so, as this all involves some pretty complicated physics. But in short, the takeaway is this: Reality is at odds with itself.
Two facts, no ultimate reality

Nobel Prize-winner Eugene Wigner described a thought experiment in 1961 that highlighted an uncommon paradox of quantum mechanics. Specifically, it reveals the strangeness of the universe when two observers, like Wigner and his friend, observe two distinct realities. Since the thought experiment, physicists have used it to explore the very nature of measurement, in addition to the bizarre idea of whether objective facts actually exist or not. This is a pretty crucial feature of science, since empirical inquiry works to establish objective facts.

But if there aren't any facts, how can science presume to describe a real world in the first place?

For decades (and philosophically, much longer), this has served as a great bit for entertaining dinner guests, but Wigner's thought experiment wasn't really anything more than that. Until now.

In 2020, physicists realized that recent quantum technology advances had made it possible to create Wigner's Friend test in a real-world experiment. In essence, we can create different realities, and compare them in a lab to see if they can be reconciled, or cohere, in one system. And researcher Massimiliano Proietti of Heriot-Watt University, Edinburgh, along with a handful of researchers, said they performed this long-awaited experiment for the first time: Creating distinct realities, compare-and-contrasting them, and discovering that they are, in fact, irreconcilable.


Quantum entangled photons reproduced Wigner's thought experiment

Wigner's initial thought experiment was simplistic in principle, starting with a single polarized photon that can have either vertical or horizontal polarization, upon measuring. The laws of quantum mechanics hold that a photon exists in both states of polarization simultaneously, in what's called superposition. In his thought experiment, Wigner imagined a friend measuring the state of a photon in a different lab and recording the result while Wigner watched from afar. He has no clue what his friend's measurement is, and is thus forced to assume that the photon and its measurement are in a state of superposition of every possible outcome for the experiment.

Wigner can say, however, that the "fact" of the superposition's existence is real. And, strangely, this state of affairs suggests that the measurement can't have taken place. Obviously, this stands in direct contradiction to Wigner's friend's point-of-view, who just measured and recorded the photon's polarization. He can even call Wigner and tell him the measurement was taken, without revealing the results. This means there are two realities at odds with one another, and it "calls into question the objective status of the facts established by the two observers," explained Proietti and colleagues, in an MIT Technology Review report.

And the new research reproduced Wigner's thought experiment by using entanglement techniques for many particles at the same time.

This is a breakthrough experiment from Prioretti and his colleagues. "In a state-of-the-art 6-photon experiment, we realize this extended Wigner's friend scenario," they added in the report. And it raised some baffling questions that have forced physicists to confront the nature of reality. There might be a loophole to some assumptions that made this unknowable reality conclusion necessary, but if everything holds up to future scrutiny, it turns out reality does not exist.

So the next time your friends think something is or isn't the case, consider interjecting with an argument from quantum physics: they're both wrong, and so are you, because even the simple fact of the disagreement itself is just another illusion.

NASA’s Perseverance Rover Successfully Cores Its First Mars Rock – “A Phenomenal Accomplishment!”

Perseverance will obtain additional imagery of the sample tube before potentially completing the process of collecting its first scientifically-selected Mars sample.

Data received late September 1 from NASA’s Perseverance rover indicate the team has achieved its goal of successfully coring a Mars rock. The initial images downlinked after the historic event show an intact sample present in the tube after coring. However, additional images taken after the arm completed sample acquisition were inconclusive due to poor sunlight conditions. Another round of images with better lighting will be taken before the sample processing continues.

Obtaining additional imagery prior to proceeding with the sealing and storing of Mars rock sample is an extra step the team opted to include based on its experience with the rover’s sampling attempt on August 5. Although the Perseverance mission team is confident that the sample is in the tube, images in optimal lighting conditions will confirm its presence.

Perseverance’s Sampling and Caching System uses a rotary-percussive drill and a hollow coring bit at the end of its 7-foot-long (2-meter-long) robotic arm to extract samples slightly thicker than a pencil. Within the bit during coring is a sample tube. After completing yesterday’s coring, Perseverance maneuvered the corer, bit, and open end of the sample tube in order to be imaged by the rover’s Mastcam-Z instrument. The target for the sample collection attempt was a briefcase-size rock belonging to a ridgeline that is more than half-a-mile (900 meters) long and contains rock outcrops and boulders.

The initial set of images from Mastcam-Z showed the end of a cored rock within the sample tube. After taking these images, the rover began a procedure called “percuss to ingest,” which vibrates the drill bit and tube for one second, five separate times. The movement is designed to clear the lip of the sample tube of any residual material. The action can also cause a sample to slide down farther into the tube. After the rover finished the percuss-to-ingest procedure, it took a second set of Mastcam-Z images. In these images, the lighting is poor, and internal portions of the sample tube are not visible.

“The project got its first cored rock under its belt, and that’s a phenomenal accomplishment,” said Jennifer Trosper, project manager at NASA’s Jet Propulsion Laboratory in Southern California. “The team determined a location, and selected and cored a viable and scientifically valuable rock. We did what we came to do. We will work through this small hiccup with the lighting conditions in the images and remain encouraged that there is sample in this tube.”

Commands uplinked to the rover earlier today will result in images of the corer and tube to be acquired tomorrow, September 3, at times of day on Mars when the Sun is angled in a more favorable position. Photos will also be taken after sunset to diminish point-sources of light that can saturate an image. The photos will be returned to Earth early in the morning of September 4.

If the results of this additional imaging remain inconclusive, the Perseverance team still has several options to choose from going forward, including using the Sampling and Caching System’s volume probe (located inside the rover’s chassis) as a final confirmation of the sample being in the tube.

The September 1 coring is the second time that Perseverance has employed its Sampling and Caching System since landing in Jezero Crater on February 18, 2021.

More About Perseverance

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Subsequent NASA missions, in cooperation with ESA, would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

The NASA Perseverance rover's mission to look for signs of past life on Mars takes us deep inside a rock named "Rochette".

One of the primary missions for NASA's Mars rover, Perseverance, is looking for evidence of past life. Some of that evidence is hidden away deep inside of Martian rocks.

That's what led Perseverance to drill into one particular briefcase-sized rock and, for the first time during its still-young mission, collect a core sample. Images and data that NASA received on Sept. 1 confirmed that the rover's first coring attempt was (probably) a success.

There's a whole process here that starts with a more superficial look at the Mars surface. Perseverance is fitted with several tools for interacting with the environment, including a Rock Abrasion Tool (RAT), which is "a high-speed grinder with brushes to remove that weathered outer layer of rock and clear away dust," and a Gaseous Dust Removal Tool (GDRT) that, as its name suggests, clears away the dust at the site of the abrasion.

This first part of the process gives the rover an opportunity to use some other built-in instruments to examine the targeted rock even more closely. The data gathered from there helps NASA engineers decide if it's worth moving on to the next step of trying to obtain a core sample.


This whole process unfolded earlier in August, which led in turn to Perseverance's first attempt to core a Martian rock. Things didn't go according to plan that time, as NASA explained in an Aug. 11 post.

While the rover's seven-foot drill successfully bored its way into the rock and seemed to come away with a sample, images beamed back to Earth showed an empty storage tube. Unfortunately, that revelation occurred only after the tube was sealed and stored for future retrieval. It turned out that the rock itself wasn't the best candidate for coring.

For the latest attempt, which appears to have been a success, the NASA team back on Earth learned from their earlier experiences. This time, they used one of the Perseverance rover's onboard cameras, Mastcam-Z, to snap an image of the sample tube — or at least, the top of it — before sealing it away for storage.

The first look is encouraging, with actual rock clearly visible in the open end of the sample tube. But that's only the first step before storage. Once a sample is collected, the rover kicks off a procedure called "percuss to ingest" which rattles the sample tube five times in brief, one-second bursts. The goal is to clear any excess residue from the lip of the tube, but that shaking can also send collected material deeper down.

That appears to be what happened here. While NASA's first shot of the tube's open end clearly shows there's something inside, a second shot, captured after the "percuss to ingest" process, shows only a dark space.

Again heeding the lessons of the first coring attempt, NASA isn't quite ready to call this coring operation a total success. Before the tube gets sealed off for storage, the Mastcam-Z will go to work once again "at times of day on Mars when the Sun is angled in a more favorable position." The hope is that a new crop of images taken in different light will offer a clearer look into the sample tube.

No one's expecting failure at this point, however.

"The project got its first cored rock under its belt, and that’s a phenomenal accomplishment," said Jennifer Trosper, project manager at NASA's Jet Propulsion Laboratory (that's the team in charge of the Perseverance project). She added: "We did what we came to do. We will work through this small hiccup with the lighting conditions in the images and remain encouraged that there is sample in this tube."

It's going to be some time before the samples collected by Perseverance are actually safely ensconced on Earth. If all goes according to plan, the rover's bounty will arrive here sometime in 2031 at the end of a three-stage "Mars Sample Return" (MSR) mission.


The Solar System’s Oort Cloud May Harbor an Astonishing Number of Objects from Other Stars

Contrary to what we’ve long assumed, this reservoir of comets surrounding the solar system may have more visitors than permanent residents

‘Oumuamua, the first interstellar object discovered near the Earth, left us with more questions than answers. The visitor was first observed during its exit from the solar system, and the limited data that astronomical observatories were able to collect have proved challenging to explain. What we know is that ‘Oumuamua was neither a comet nor an asteroid, and none of the exotic theories regarding its origin to date has been able to fully explain its properties.

Two years later, though, the second interstellar visitor was spotted—and it couldn’t have been further from ‘Oumuamua in nature. Borisov exhibited an uncanny resemblance to comets originating from the distant reaches of our own solar system, yet it traveled on a clearly hyperbolic orbit. As the first interstellar comet, Borisov’s similarities to known objects in the solar system allow for an exciting opportunity never afforded by ‘Oumuamua: a direct comparison between the solar system and its cosmic neighborhood.

In a recent paper in Monthly Notices of the Royal Astronomical Society: Letters, we report for the first time the unintuitive reality that the discovery of the first interstellar comet revealed: the Oort cloud, our solar system’s vast reservoir of comets, which extends halfway to the nearest star, harbors more visitors than permanent residents. Near the Earth, comets originating from within the solar system outnumber those from outside of the solar system—hence the fact that there has been only one definitive interloper since the first comet was detected with a telescope by Gottfried Kirch in 1680. But the observations that have been performed are unrepresentative of most locations in the solar system, since they are biased by our proximity to the sun.

As a result of gravitational focusing, the sun preferentially attracts comets from within the solar system, like a lamppost beckoning swarms of moths. On the other hand, interstellar objects, which whiz about the galaxy at high speeds, are nearly impervious to the sun’s gravitational pull, and so don’t cluster near the sun in the same way that Oort cloud objects do. Our new work shows that there are so many of them that, despite their speed, there are far more interstellar interlopers in the dark reaches of the solar system at any given time than there are comets of local origin.

This conclusion has profound effects for future observations and theories alike. It motivates new searches for objects in the Oort cloud, including stellar occultation surveys like TAOS II that scan the sky for blips in starlight resulting from the chance alignments of nearby objects and distant stars. At the same time, the new finding directly challenges our theoretical understanding of how planets form, since it implies that planetary systems must throw out orders of magnitude more mass than previously thought. In fact, our new paper shows that stars may have to expel at least as much mass as they keep—a striking new constraint on planetary system formation.

Future discoveries of interstellar objects will continue to inform our understanding of the solar system in its galactic context. The Legacy Survey of Space and Time (LSST) on the Vera C. Rubin Observatory, scheduled to begin operations in late 2023, is expected to discover at least one interstellar object per month, a rate that will help us pinpoint the origins of interstellar objects, and learn more about how stars and planetary systems form. The most exciting scientific revelations regarding interstellar objects, however, will likely come from the direct study of interstellar matter. What are these surprisingly abundant objects made of? At the cost of a few hundred million dollars, the European Space Agency’s Comet Interceptor mission might be able to sample the gaseous tail of an object like Borisov in the 2030s, if one approaches the sSun at the right time, speed and direction.

There’s also another way to search for interstellar objects, and even to obtain humanity’s first samples of matter originating from outside of the solar system, at relatively low cost and from the comfort of Earth’s surface. Any material coming into contact with our planet’s atmosphere burns up from friction with the air, appearing briefly as a streak of light in the sky: a meteor. As a result, it is much easier to find small objects in the atmosphere than in space, where we would have to rely on reflected sunlight. And while the atmosphere provides a much smaller search volume than the reaches of space, the abundance of smaller interstellar objects should be great enough to make searching for interstellar meteors an attractive idea.

In fact, while analyzing a publicly accessible U.S. government data set of meteors in 2019, I found one recorded impact that seemed to have approached far too quickly to have been bound to the solar system. I could hardly believe this, as astronomers have been searching for an interstellar meteor since 1950 or earlier. This discovery would later be tentatively confirmed as the first interstellar meteor larger than dust, and since then Pentagon officials have expressed interest in potentially declassifying the error bars associated with the detection, given its immense scientific value.

As director of interstellar object studies of the Galileo Project, I am leading an effort to discover gram-scale interstellar meteoroids in our atmosphere, using unclassified and transparent sensor networks. In concert with the interstellar objects that LSST will detect in Earth’s neighborhood, such discoveries would revolutionize our understanding of the solar system in the context of its peers. The holy grail of interstellar meteoroids would be a kilogram-scale or larger object that burned up above land, since such events might leave easily recoverable meteorites—rocks that could represent the first pieces of interstellar matter ever obtained by humanity. Such a goal could be accomplished in a decade for only a few tens of millions of dollars—a budget 10 times smaller than the Comet Interceptor mission—with a thousand globally distributed passive all-sky camera systems patiently waiting for the proverbial needle-in-a-haystack meteoroid to grace our planet.

One of the most beautiful aspects of the study of interstellar objects is that it connects so many disparate fields in astrophysics, spanning planetary science to high-energy phenomena and incorporating an equally diverse array of methods for detecting them. Along with other branches of “multimessenger” astronomy that seek to supplement traditional methods of astronomical inquiry, like gravitational-wave and neutrino surveys, searches for interstellar objects could help reveal unprecedented insights that challenge the way we understand our place in the universe.

Geologists Propose A Theory About


Asteroid Vesta

The asteroid Vesta

The asteroid Vesta is the second largest asteroid in our solar system. With a diameter of about 330 miles, it orbits the sun between the planets Mars and Jupiter.

Asteroids have long played a part in building popular fascination with space. "Marooned off Vesta" was the first story published by American writer Isaac Asimov, the third story he wrote, appearing in the March 1939 issue of the science fiction magazine Amazing Stories.

"When we think of asteroid belts, we probably picture Han Solo maneuvering the millennium falcon through a dense set of irregularly shaped gray rocks in space," Christian Klimczak, associate professor in the Franklin College of Arts and Sciences department of geology. "While most rocks are indeed irregularly shaped and gray, they are far apart and NASA's Dawn spacecraft did not have to maneuver around any other asteroids to reach and explore Vesta."

Dawn was the space probe launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt, Vesta and Ceres.

Vesta, like Earth, is composed of rock in its crust and mantle, and it has an iron core. Because of its large size (for an asteroid) and because Vesta has a crust, mantle and core, it is considered a planetesimal. Planetesimals are building blocks out of which planets form. Earth formed by accretion of several such planetesimals. "Vesta was on the way to becoming an Earth-like planet, too, but planet formation stopped along the way there early in the history of our solar system," Klimczak said. "Therefore, studying Vesta helps us understand the very early days of our planetary neighborhood and how our own planet formed."

Klimczak is co-author on a new study that examines the large-scale troughs and impact basins on Vesta.

What created those giant troughs on Vesta?

Vesta was hit by two other large asteroids which left large impact craters so big they cover most of the southern hemisphere of Vesta. These impacts are thought to have ejected rocky material into space. Some of these rocks reached Earth as meteorites so scientists now have actual rock samples from Vesta to study its geochemistry.

"Rock properties are influenced by environmental conditions like surrounding stresses and the presence of water," said Jupiter Cheng, doctoral candidate in the department of geography and co-author on the study. "Since Vesta is much smaller than Earth, or even the moon, it has a weaker gravity, and rock would deform differently near the surface than what we see on Earth."

According to Cheng, one big question is what triggered the formation of these large troughs. The two troughs are concentric around the two massive impact basins, Rheasilvia and Veneneia, respectively, and widely considered to be simultaneously formed by the impact events, though this assumed age relationship has never been tested before.

"Our work used crater counting methods to explore the relative age of the basins and troughs," Cheng said. Crater counting is a common method for estimating the age of a planet's surface, a method based upon the assumptions that when a piece of planetary surface is new, then it has no impact craters; impact craters accumulate after that at a rate that is assumed known.

"Consequently, counting the number of craters of various sizes in a given area allows us to determine how long they have accumulated and, consequently, how long ago the surface formed," she said. "Our result shows that the troughs and basins have a similar number of the crater of various sizes, indicating they share a similar age. However, the uncertainties associated with the crater counts allow for the troughs to have formed well after the impacts.

The origin of the troughs has long been a point of conjecture within the scientific community. Klimczak hopes their new geologic evidence can promote a more-durable theory about the troughs on Vesta.

The study is published in the September issue of the journal Icarus.

A new theory is proposed in an upcoming paper

"The leading hypothesis suggests that these troughs are fault-bounded valleys with a distinct scarp on each side that together mark the down-drop (sliding) of a block of rock. However, rock can also crack apart and form such troughs, an origin that has not been considered before," said Cheng, who is investigating the origin of the troughs as part of her dissertation at UGA.

"Our calculations also show that Vesta's gravity is not enough to induce surrounding stresses favorable for sliding to occur at shallow depths, instead, the physics shows that rocks there are favored to crack apart," she said. "Therefore, the formation of these troughs must involve the opening of cracks, which is inconsistent with the leading hypothesis in the scientific community. Taken all together, the overall project provides alternatives to the previously proposed trough origin and geological history of Vesta, results that are also important for understanding similar landforms on other small planetary bodies elsewhere in the solar system."

The new study was presented at the European Geosciences Union General Assembly 2021.

AUSSIE MINERS ARE IN ALBERTA DIGGING OUR COAL

Coal’s future is ‘assured’ says Australia in response to UN

UN climate envoy urged Australia to phase out coal saying climate change will dramatically damage its economy, .

Coal will be a big contributor to Australia’s economy well beyond 2030 given growth in global demand, the country’s resources minister has said, a day after a United Nations envoy called on the country to phase out the fossil fuel.

Without greater efforts to cut coal, climate change will dramatically damage Australia’s economy, Selwin Hart, the United Nations special adviser on climate change, said in a speech in the capital Canberra on Sunday. Australia made the announcement on Monday.

Australia is the world’s third-biggest emitter on a per capita basis, with coal still accounting for about 60 percent of its power generation. Its conservative government has steadfastly backed fossil fuel industries, saying tougher action on emissions would cost jobs.

Australia’s latest export figures show “the reports of coal’s impending death are greatly exaggerated and its future is assured well beyond 2030,” Resources Minister Keith Pitt said in a statement.

In the three months to July, Australian coal exports grew 26 percent in value to 12.5 billion Australian dollars ($9.3bn), he noted. Coal prices have climbed as global economies recover from COVID-19 restrictions.

“The future of this crucial industry will be decided by the Australian government, not a foreign body that wants to shut it down costing thousands of jobs and billions of export dollars for our economy,” Pitt added.

The UN has called for phasing out coal by 2030 in the Organisation for Economic Cooperation and Development countries, which include Australia.

In July, energy and environment ministers from the Group of 20 big economies failed to deliver a deal to phase out coal by 2025. But some experts said there were chances of progress at UN climate talks in Glasgow in November.

Prime Minister Scott Morrison has said Australia is on a path to net-zero carbon emissions but has stopped short of committing to a timeline. He has said that Australia would update its 2030 emissions projections before the Glasgow talks.

Australia stands by coal 'beyond 2030' after UN warns of economic havoc

A bucket-wheel reclaimer by a pile of coal at the Port of Newcastle in Australia on October 12, 2020.

London (CNN Business)The Australian government said Monday that the country would keep producing and exporting coal "well beyond 2030," despite a stark warning from a top UN climate official that failing to scrap the fossil fuel will "wreak havoc" on the economy.

The comments, made in a rebuke by the minister for resources and water, Keith Pitt, puts Australia at odds with several other developed nations, which are working towards phasing out coal by the end of the decade.

"The future of this crucial industry will be decided by the Australian Government, not a foreign body that wants to shut it down costing thousands of jobs and billions of export dollars for our economy," Pitt said in a statement Monday.



John Kerry is pushing China drop coal. Beijing is pushing back
In his 360-word statement, the minister listed a number of economic benefits coal has brought the Australian economy but made no mention of the climate crisis.

Pitt's statement added that figures showing coal's "impending death are greatly exaggerated and its future is assured well beyond 2030."

"Coal consumption throughout Asia is forecast by the International Energy Agency to grow over the next decade to meet the energy demands of countries like China, India and South Korea," Pitt said.

"Australia has an important role to play in meeting that demand. Coal will continue to generate billions of dollars in royalties and taxes for state and federal governments, and directly employ over 50,000 Australians."

Australia is the second-largest exporter of coal in the world and the country has a high per capita carbon footprint, largely because of its coal industry. An Australian emits an average of 17 metric tons of carbon dioxide, while the global average is less than 5 tons per person, European Commission data shows.

Of the world's 176 new coal projects, 79 of them are in Australia, according to Fitch Solutions' Global Mines Database.



Protesters against the Adani coal mine, now named Bravus, march through the streets of Brisbane on July 5, 2019.

Pitt made his comments as the UN's top climate envoy, Selwin Hart, said the global phase-out of coal was not happening fast enough "to avert a global climate catastrophe."

"We fully understand the role that coal and other fossil fuels have played in Australia's economy, even if mining accounts for a small fraction — around 2% — of overall jobs," Hart said during a video address to the Crawford Leadership Forum at the Australian National University on Monday.

"But it's essential to have a broader, more honest and rational conversation about what is in Australia's interests, because the bottom line is clear: If the world does not rapidly phase out coal, climate change will wreak havoc right across the Australian economy, from agriculture to tourism, and right across the services sector. Similarly, construction, housing and the property sector, in a country where the vast majority live on or near a coastline. It will be even more catastrophic in your neighborhood."

Hart added that business and investors were increasingly abandoning coal in favor of renewable energy that is now cheaper in most places.

By not cutting coal, Australia is setting itself up for a future of climate disasters such as droughts, heatwaves, fires and floods, which will become more frequent and severe as the planet warms.

"It is increasingly clear that decarbonization is inevitable, and it is the greatest commercial opportunity of our age," Hart said, adding that the world is "at a critical juncture in the climate crisis."

Australia's climate record
Coal is the biggest single source of carbon emissions in the world, and the UN has called on OECD countries, including Australia, to phase out the fossil fuel by 2030.
China is the world's biggest consumer and producer of coal, accounting for around 50% of the world's production, and pressure is growing on the country to phase out the fossil fuel quicker than planned.



Air pollution is cutting more years from people's lives than smoking, war or HIV/AIDS
Scientists say key economies must cut carbon pollution by 45% this decade if the world is to contain average global temperature rises to 1.5˚C above pre-industrial levels. Going beyond that, scientists say, will mean more frequent and intense climate impacts, including droughts, heatwaves and wildfires, as well as heavy rainfall and floods.
Australia has pledged to reduce its greenhouse gas emissions by 26-28% by 2030, from 2005 levels, a pledge that sits well below renewed commitments by the United States, European Union and United Kingdom, among other developed nations.

US President Joe Biden increased his country's pledge in April to reduce emissions by 50-52% in the same timeframe.

Australia, like dozens of other countries, missed a July 31 deadline, laid out in the 2015 Paris Agreement, to increase its pledge, though the government says it will do so ahead of the COP26 international climate talks to be held in Glasgow in November.

Australia has also not committed to net zero emissions by mid-century, a goal that the United States, European Union and United Kingdom, among other countries, have done. Net zero is where the amount of greenhouse gas emitted is no greater than the amount removed from the atmosphere.

Prime Minister Scott Morrison has said Australia is aiming to reach zero "as soon as possible," and preferably by 2050, but has stopped shot of anything more concrete. Many Australian states have, however, committed to net zero independently of the central government.

Much of the developed world is switching to renewable sources to generate electricity, while Australia's power grid remains heavily coal-reliant.

Coal is, however, still used extensively around the world for heavy industry, such as steel making, where energy from sources like wind and solar are not able to meet power requirements. Alternatives, like green hydrogen, are in development and are slowly coming into wider use.
World-renowned architect pushes for an environmentally friendly arena

Disappointed in the 
Kingsway
Entertainment District’s location, Jason McLennan wants to see the new arena at the very least be net-zero.

A world-renowned figure in the field of architecture and the green building movement has been watching with great interest as the Kingsway Entertainment District project has proceeded.

“I’d like to see Sudbury thrive and live up to its potential, and that’s why I was disappointed to learn about the idea of moving the arena out of downtown,” Jason McLennan said.

“If you pull the focus away from downtowns you really diminish it and all you do is increase vehicle travel and you create urban sprawl and you hurt public transportation and so on and so forth, and it’s really an unfortunate move.”

Although his base of operations is currently in Seattle, McLennan was born and raised in Sudbury, still has family in the city and wants to see his home community succeed.

Last year, he presented an idea for Sudbury’s Superstack which he envisioned as becoming the world’s tallest solar energy source.

McLennan has not been involved in the Sudbury arena project and clarified he doesn’t want to criticize the people behind the project, as he doesn’t know them and hasn’t spoken with them.

That said, he yields significant expertise in the fields of not only the green building movement but also arenas in particular.

McLennan and his firm McLennan Design, which he is CEO of, served as the lead sustainability consultant for the Climate Pledge Arena in Seattle, Wash. The arena will serve the Seattle Kraken NHL team and come at a cost greater than $1 billion.

“It will be the greenest arena on the planet and sets new benchmarks for sustainability as well as being great for the city,” he said. “It’s a great example of thinking differently about existing assets and making it work. If you can do it for the NHL you can do it for the OHL.”

His nod to the OHL is in reference to the Sudbury Wolves, whose games are poised to shift from the downtown-based Sudbury Community Arena to the Kingsway Entertainment District located off of The Kingsway near the Sudbury Landfill Site after it opens in late 2024.

The arena project is a new build that includes a $100-million capital investment by the municipality and cost-sharing agreements with partners, and has been approved by Greater Sudbury city council, which is expected to receive an update during their Sept. 14 council meeting.

Although the city’s elected officials considered downtown for a new or renovated arena in 2017, a 6-6 vote by the city council of the day defeated the motion, shifting their attention to its currently approved location.

Prior to a decision was made in Seattle, McLennan said the community was shown a report on how their historic arena, built in the 1960s, could be modernized and improve its surrounding area.

“When the community saw that they were incredibly excited about it,” he said. “We were reusing the structure, the roof, the infrastructure.”

In Sudbury, Ward 4 Coun. Geoff McCausland presented a motion in June for city staff to undertake an analysis of potential approaches for modernizing the Sudbury Community Arena, but it was narrowly defeated.

“If I was a citizen of Sudbury, I would have wanted to see beautiful designs and renderings and analysis of how the existing arena could have been updated,” McLennan said.

But, given that shutting down the KED at this point would require a three-quarters vote of council, which doesn’t appear to be their current bend, its currently approved location stands.

McLennan said that if they stay firm on the location, the city should at the very least construct a net-zero building.

“There would be no energy bill, no hydro bill, it would be a living building as I call it; there would be no water bill,” he said, adding that city council’s 2019 unanimous declaration of a climate emergency behooves them to keep environmental stewardship at top of mind.

“It’s not only because of the environmental benefits but also the economic benefits, and there’s a lot of misinformation and old information people have about it having to cost a lot,” he said.

“It’s about making investments in the future. ... The economic returns are very positive, and that’s why we’re seeing more and more facilities going green.”

Those behind the Climate Pledge Arena in Seattle have made a number of environmental commitments, including that the facility be carbon neutral, utilize no single-use plastics, conserve water and produce zero waste.

The arena, McLennan said, will be powered completely by renewable energy and will hook up with solar panels both on-site and off-site.

“We’re even making our ice from rainwater, so we’re capturing rainwater and making what I think will be the greenest ice in the NHL.”

Although he has been watching the KED proceed from afar, McLennan said he’d be eager to speak with city council and stakeholders if they are so inclined.

“I’d be open to sharing my experience and knowledge in working with arenas and with the NHL and working with cities,” he said. “I’ve been a consultant to quite a few cities over the years, and I’m happy to talk to the city.

“I really think the city needs to understand in 10 years from now what this would look like, both in location and truly what it would look like if they did what we did in Seattle and reinvested in existing assets.”

City of Greater Sudbury Energy and Emissions Plan

In response to an inquiry about City of Greater Sudbury policies related to environmentally friendly builds, a communications representative pointed to the Community Energy and Emissions Plan (CEEP).

This, they explained, is the city’s long-term plan to reduce carbon emissions. The plan came in response to city council’s 2019 climate emergency declaration and works toward achieving net-zero emissions by 2050.

The plan includes 18 goals in eight strategy sectors, including three under the efficient buildings umbrella, including:
Goal 2: Periodically increase the energy efficiency of new buildings until all new buildings in 2030 onward are Passive House energy efficiency compliant.
Goal 3: The existing building stock is retrofit for 50 per cent increased energy efficiency by 2040 and large buildings are routinely recommissioned.
Goal 4: Achieve net-zero emissions in City buildings by 2040.

Under Goal 3, the city is striving to develop an energy efficiency retrofits program for which they recently received $170,000 in funding from the Federation of Canadian Municipalities to do a study comparing home retrofit financing models.

Under Goal 4, the city is developing a prioritized list of municipal buildings to perform energy audits, payback analyzes and retrofits on starting with the highest priority buildings.

As for the KED, the spokesperson noted the city is currently looking at how the CEEP goals will tie into the project, which will be outlined in future reports to city council.

In a July 14 report to city council, it’s noted, “From the perspective of the CEEP, the project respects the objective to minimize the production of greenhouse gases in the operation of new assets.”

‘No point in anything else’: Gen Z members flock to climate careers

Colleges offer support as young people aim to devote their lives to battling the crisis

California is facing a drought so devastating, some publications call it “biblical”. Colorado now has “fire years” instead of “fire seasons”. Miami, which sees more dramatic hurricanes each year, is contemplating building a huge seawall in one of the city’s most scenic tourist districts to protect it from storm surges.

“Once you learn how damaged the world’s ecosystems are, it’s not really something you can unsee,” says Rachel Larrivee, 23, a sustainability consultant based in Boston. “To me, there’s no point in pursuing a career – or life for that matter – in any other area.”

Larrivee is one of countless members of Gen Z, a generation that roughly encompasses young people under 25, who are responding to the planet’s rapidly changing climate by committing their lives to finding a solution. Survey after survey shows young people are not just incorporating new climate-conscious behaviors into their day-to-day lives – they’re in it for the long haul. College administrators say surging numbers of students are pursuing environmental-related degrees and careers that were once considered irresponsible, romantic flights of fancy compared to more “stable” paths like business, medicine, or law.


“I cannot imagine a career that isn’t connected to even just being a small part of a solution,” says Mimi Ausland, 25, the founder of Free the Ocean, a company that aims to leverage small actions to remove plastic from the ocean.

Democrats in Washington hope to channel this energy through the proposed Civilian Climate Corps, a federal jobs program for young people to help fight the climate crisis and conserve public lands. While funding for the New Deal-inspired program is tied up in budget negotiations on Capitol Hill, youth activists say they hope it would help kids fresh out of high school land environmental-related jobs.

“The Civilian Climate Corps would actually allow a lot of young people to have a direct pipeline to these careers,” says Matt Ellis-Ramirez, 22, a Chicago-based volunteer for the youth-led environmental activist organization the Sunrise Movement.

Young people are finding their way to these careers, though, with or without the federal government’s support. Brooke Hoese, a 24-year-old undergraduate in Texas pursuing a career in restoration ecology, is taking an interdisciplinary approach. They spent the summer working on a farm that practices regenerative agriculture, a method to restore soil biodiversity, to contribute toward an integrative studies degree involving ecology, literature, and philosophy.

“My goal is to use the lens of literature and philosophy to study and hopefully help repair humans’ relationship to our environments,” they say.

College campuses across the country are now finding new ways to help students like Hoese integrate climate studies across various disciplines. The University of Southern California in Los Angeles, for example, launched the Sustainability Across the Curriculum program earlier this year to teach the college’s 20,000 undergraduate students how their majors intersect with sustainability and the environment.

I think I’m in the last generation who may be able to do anything about climate change

A 2020 USC survey found that 64% of undergraduate students are “very interested” in on-campus sustainability, while 27% are “interested”. They’re also practicing what they preach: 33% of survey respondents say they participate in sustainability activities “daily” and 27% report weekly sustainability practices.

“In the past, interest in the environment and sustainability was probably more of a niche interest, whereas now I see students that are studying in many different fields across campus also have an interest in sustainability,” says Jill Sohm, the director of the Environmental Studies program at USC. She says there’s been an uptick in student enrollment within her department, particularly over the last five to 10 years.

Christopher Schlottmann, the global curriculum coordinator at New York University’s environmental studies program, reports similar growth. And while the job market is rough across the board for new grads, Schlottmann says having some form of environmental degree under their belt is an asset, not a hindrance.

“There’s a general reputation that if you do good for the world, nobody’s going to pay you to do it. I don’t think that’s that accurate,” he adds. “If you understand how climate change works, then a bank should actually really want to talk to you because they want to hedge their risk.”

The United States Bureau of Labor Statistics projects that employment opportunities for environmental scientists and “related specialists” will grow 8% over the next 10 years, a rate much faster than growth in other industries. And pay ranges notably above overall median income levels: the 2020 median pay for environmental scientists is $73,230 per year, while environmental lawyers earn a median yearly salary of $122,960. Urban farmers, a career path that doesn’t require a bachelor’s degree, make roughly $71,160 a year.

“We grow up being told that working in environmental fields is a dream that is not accomplishable. And there’s no money in it,” says Ellis-Ramirez. “But as we start to realize that the world that we live in isn’t sustainable, and that corporations will stop making money if we lose the planet, then that funding is going to start showing up.”

Other young people note that a variety of industries now incorporate environmental issues into their work, giving young professionals flexibility to pursue a variety of career paths. “Things like sustainability aren’t fringe – they’re really mainstream,” says Joel Hartter, the director of the new outdoor recreation economy graduate program at the University of Colorado, Boulder. “I think that translates into people seeing that they have career options.”

As attention to the environment grows, so too does Gen Z’s awareness of how the climate crisis and pollution disproportionately harm marginalized communities.

“Environmental issues are not just environmental issues, but rather one avenue to help address other issues in society,” says Brooke Majewski, 23, a recent college graduate who works at a company that helps businesses achieve their sustainability goals. “It is about finding solutions for the planet we are on, but it is also finding solutions for the people being most negatively impacted by climate change.”

Surveys indicate that shifting attitudes toward the crisis often fall along generational lines. A 2021 Pew Research report found that Gen Z is overwhelmingly worried about climate change: 76% of them say that it’s one of their biggest societal concerns, while 37% make it their number one concern.

According to Pew, 32% of Gen Z respondents have participated in at least one major environmental action of the course of the past year, such as donating, volunteering, attending a rally, or contacting an elected official. In contrast, 23% of Gen X and 21% of baby boomers reported participating in such an action during the past year.

“I decided to pursue this industry because I think I’m in the first generation who knows the extent to which climate change poses an existential threat to life on Earth, and also the last generation who may be able to do anything about it,” says Larrivee, the Boston-based environmental consultant.

Solutions to the planet’s grim environmental future are in reach thanks in large part to this army of young people flooding universities, job fairs, and interview rooms with clear-eyed confidence in science, policy, and each other. This enthusiasm is historically unprecedented, says Schlottman.

“This is not a preset problem with a preset solution,” he says. But “their hearts are in the right place, and their minds are really close to in the right place too”.
