Western Sydney goes to be the most popular place on Earth in just some months.
That’s the grim warning from an city planner who says our relentless push west – within the title of fixing the housing disaster – is making a liveability nightmare.
In a frank video that has gone viral on TikTok, JOC Consulting senior city planner Samuel Austin visits a brand new housing growth in Marsden Park, about 50km northwest of the Sydney CBD, the place he expects temperatures will soar this summer season.
In six months’ time, he mentioned, will probably be “the hottest place on earth”.
Some of the 1000’s who watched the video commented in shock on the warning, whereas others shared their very own tales of the “concrete nightmare” that’s the housing property, some likening them to “hell on earth”.
“I used to take my child to a GP in Marsden Park. Summer about [three] years ago I was driving him home from the GP and the car temp gauge was [50 degrees],” one mum mentioned.
“Gregory Hills in [southwest] Sydney is the same. The new development at Menangle has white roofs. But still no extra trees planted,” one other replied.
However, Mr Austin informed news.com.au the massive housing estates just like the one at Marsden Park – with their tiny backyards, black rooves, and concreted every part – weren’t simply unbearably scorching, however had created harmful city warmth islands that may attain temperatures as much as 50C.
“Western Sydney is naturally hotter than the rest of Sydney, about two-degrees warmer than it is in the east,” Mr Austin mentioned.
“But now we’re seeing temperatures sitting up to 10 and 12 degrees hotter above that baseline temperature, and that is driven entirely by urban development, these new housing estates, and urban release areas.”
Urban warmth islands develop in areas with an abundance of exhausting, sealed surfaces like concrete, metallic, asphalt, bricks, and lack of greenery and vegetation – like these housing estates.
The concern, Mr Austin says, is that whereas nature can take up the warmth from the solar, a “non-permeable surface like concrete and roofing … spits it back out”.
Even one thing so simple as the color of the home’s roof, or the grass laid within the yard is impacting temperatures.
“It’s purely a decorative choice to have a black roof, it’s just the paint colour. There’s no difference in price, but we know a black roof is at least six degrees hotter than a white roof” he mentioned.
“And synthetic grass. I can’t believe walking around [Marsden Park] the fake grass everywhere. It absorbs way more heat, but it’s about the same cost of getting the real stuff.”
What’s extra, the shortage of plant and vegetation cowl in these areas additionally implies that typically there’s much less water within the panorama, which implies there’s much less transferring from by means of the ambiance – through evapotranspiration – which helps cool the atmosphere.
He mentioned these elements amplified the impact local weather change was having.
While harmful temperatures have been affecting decrease earnings and weak households.
“Western Sydney is traditionally more socio-economically disadvantaged than other areas, the most vulnerable people in Sydney are living out there,” he mentioned.
“A lot of people are living in these new houses…people who are vulnerable are put at risk.
“Not to mention you have to rely heavily on airconditioning to cool down the house, which only adds to the stresses in a cost of living crisis. And if that [cooling] breaks down, it can be life-threatening, particularly to older people in these locations.”
Research and climate data have proven summer season temperatures have been climbing in latest many years – and any Sydneysider will inform you – if it feels scorching within the CBD, the temperatures are scorching within the west.
On January 4, 2020 Penrith was the most popular place on earth, with temperatures peaking slightly below 50C whereas the realm by the Harbour Bridge topped out greater than 5 levels cooler.
Then in March this 12 months, Sydney recorded its hottest month this summer season; with knowledge displaying the west isn’t solely seeing hotter days (and extra of them) than coastal Sydney, however the hotter summers are lasting longer.
Modelling from the Australia Institute in 2022 estimated western Sydney might have excessive warmth – temperatures over 35C – for 46 days per 12 months by 2090 until greenhouse emissions drop considerably.
That’s 5 occasions the historic common of 9 over-35C days per 12 months.
Extreme warmth has additionally confirmed to be the largest menace to human life, larger than some other pure hazard – together with bushfires and floods – with 4500 deaths attributable to intervals of maximum warmth since 1900, in keeping with Risk Frontiers.
During 2000 and 2018, alone, there have been 473 heat-related deaths reported, 354 of which occurred throughout heatwave situations.
And but, regardless of the warnings, there has by no means been extra growth in Sydney’s west than there’s proper now, as the federal government seems at city sprawl as the answer to the housing disaster.
But Mr Austin, and lots of different planning consultants, imagine city sprawl solely creates extra issues for Australians, given the shortage of infrastructure, expense, and inconvenience of transferring to new pop-up suburbs.
The concern, he mentioned, is that councils in western Sydney know that warmth is an “enormous problem”, however they’re “struggling to do anything” as a result of growth planning and rollout is coming from the “top down”.
He mentioned the mass growth within the west was the direct results of city launch areas introduced by the earlier NSW authorities “about 12 years ago” that “completely override council controls”.
“Councils get no say in these spaces, they get to advocate what they’d like to happen, but it’s ultimately up to the state to decide what happens,” Mr Austin mentioned.
“What’s really sad is that Blacktown Council, where Marsden Park is, is it’s a massive advocate for reducing heat, but they get little say on how prevent this [development] from happening.”
Without toppling the planning paperwork, Mr Austin mentioned there have been three comparatively low-cost options to minimising city warmth islands.
These have been addressing the “black roof issue”, laying actual grass, and making certain we’ve sufficient area to plant giant bushes with deep roots that may present a shady cover.
