Title: Future slums ... Australians can't afford trees
Post by Laugh till you cry on Mar 7th, 2024 at 12:20am
... to mitigate global warming.

The amount of tree cover and other vegetation cover in Australia is continually decreasing because Australians can't afford trees.

The heat will burn up the suburbs created as treeless plains.

Australians will have to learn survival from watching the movie Dune.

Aerial photo exposes 'serious problem' with new Aussie homes branded 'slums of the future'

Dark roofs and other surfaces are contributing to the urban heat problem, experts say.

New housing developments on the outskirts of major Australian cities are the "slums of the future" according to built environment expert Paul Osmond who says urban heat in emerging areas is a "serious problem" that needs addressing now before it's too late.

The abundance of dark surfaces like concrete, asphalt and roofing, with a lack of trees and open spaces, is contributing to record-high temperatures in already-scorching suburbs, including parts of western Sydney which has previously been the hottest place on earth in the midst of a summer heatwave in 2020. Alarmingly, new housing in areas like these is being designed to retain heat, rather than stay cool.

It's now becoming "unsustainable" and is a matter of "human health," the UNSW professor told Yahoo News Australia saying "we don't have time to play around". Hotter temperatures due to poor planning will soon enough have a detrimental impact on lives — and darker roofs, often seen on new homes and chosen for their aesthetic appeal, are partly to blame, he warned.

Dark roofs 'absorb' heat, making suburbs hotter
Aerial photos shared online recently show a housing development in Manor Lakes, west of Melbourne — a sprawling new suburb now home to 9,500 residents. Almost every house features a black or dark-coloured roof, which according to Osmond, is now a common sight sweeping new-build areas.

Lighter colours "reflect the heat back to space" whereas black or darker colours "absorb" it. "It's not a theory, it's just physics," he explained. "It contributes to what's known as the urban heat island effect".

In built-up urban areas that contain dark materials, and other built materials, like concrete, which absorb heat, Osmond said "there's less evaporation, less transpiration from plants – both of which cool an environment".

"All of these things coming together are creating a hotter environment in those new developments".

Coming to a suburb near you:

Thanks.

Idiots building houses with dark roofs:

... Nearmap analysis found that substantially more suburbs in greater Adelaide have seen a loss in residential tree canopy than have gained tree canopy.

Over the past decade:

Half of Adelaide suburbs lost at least 9.8% residential tree cover

Overall relativeresidential tree cover fell by 8.6% (20.1% in 2011, to 18.3% in 2021)

Specifically, 131 suburbs (of 281 suburbs) have lost at least 10% residential tree cover

Specifically, 18 suburbs (of 281 suburbs) have seen an increase of at least 10% residential tree cover.

Australians love to say they love trees but the truth is very different:

Trees are expensive to maintain and water

Trees block the view

Trees get knocked over by strong winds

Trees shade solar panels.

Australians can't afford trees.

Not up my way
Home to me is a 20-acre Frederick McCubbin painting



Trees are expensive to maintain and water.

Anyone with half a working brain would opt for Australian natives
They look after themselves, never require watering - being 'built' for Australian droughts



Trees block the view.

The 'view' of more trees ?


Trees get knocked over by strong winds

Rarely, but mostly from flooding rains - following long droughts - the product of climate change


Trees shade solar panels.

Why would you put solar panels in areas that shade ?
I built in full sulight



Australians can't afford trees.

Maybe best not to buy them at inner-city nurseries ?









I think that I shall never see
A poem lovely as a tree.

A tree whose hungry mouth is prest
Against the earth’s sweet flowing breast;

A tree that looks at God all day,
And lifts her leafy arms to pray;

A tree that may in Summer wear
A nest of kookaburras in her hair;

Upon whose bosom snow has lain;
Who intimately lives with rain.

Poems are made by fools like me,
But only nature can make a tree.
