The Society convenes National Science Week in Victoria, and manages Victoria's Inspiring Australia program.
Southward displacement of the Australian monsoon in the Last Glacial Period - Calla Gould-Whaley
On the current trajectory set by humanity for the planet’s climate, abrupt and dramatic changes are both anticipated and increasingly observed. Calla Gould-Whaley works to understand how past climate changes affected the Australian continent in our (geologically) recent past to better prepare for the adaptation measures required in our future.
Calla and her colleagues set out to establish the behaviour of Australia’s climate during the Last Glacial Period (LGP, the most recent ‘ice age’ ending about 11,500 years ago) by interrogating geochemical signatures in sedimentary deposits known as speleothems, a family of calcium-based cave formations that includes stalactites and stalagmites, that can provide paleoclimate records similar to those from ice cores or tree rings. She drew her samples from a cave in the Ikara-Flinders Ranges of South Australia, a region that has been historically difficult to draw data from, as proxies for past climate events are largely restricted to the coastal fringes of the continent.
The team found the speleothems at the study site were deposited during periods of enhanced groundwater recharge, when the local water table rose and flooded parts of the cave, a vanishingly rare contemporary event. During the LGP, episodes of cave flooding were sustained for thousands of years and align with intervals of Southern Hemisphere summer insolation intensity, suggesting that southern Australia received tropical moisture due to intensification and southward displacement of the Australian Monsoon. Their findings suggest this displacement was also a response to a reduced Atlantic Meridional Overturning Circulation, the main circulating current in the Atlantic Ocean, which is predicted to occur once again as anthropogenic climate change intensifies disruption from Arctic ice melt.
Calla Gould-Whaley is the First Prize winner in the Earth Sciences Category of the Royal Society of Victoria's 2024 Young Scientists Research Prizes, delivered as a part of the Inspiring Victoria program. She is completing her doctoral research at the @UniversityofMelbourne with lead supervisor Professor Russell Drysdale.

With most of Victoria’s timber and forest product resources now being derived from plantation estates, consideration must turn to how these transient forests can be supported by - and, in turn, support - regional ecology.

Advancing Mammal Conservation in the Face of Fire and Invasive Predators - Darcy Watchorn
มุมมอง 1.5K2 หลายเดือนก่อน
Each year, invasive cats and foxes kill an estimated 1.4 billion native mammals in Australia and are major drivers of Australia’s mammalian extinction crisis. Recent evidence from tropical northern Australia suggests prescribed fire regimes exacerbate these impacts by removing the understorey habitat where native prey species usually shelter to avoid detection. The sheer scale of feral predator...

Very interesting talk, I learnt alot, thank you.
1972 "Limits to Growth" quite valid analysis
Relating the eco-logy to the eco-nomy, surely our fiat form of currency is fuelling intense disparity in wealth. If you produce money from nothing then you begin an imbalance. So our money system needs to change.
Yooo so proud of you! That's really cool that you're learning to defend native wildlife like that!
that was awesome, curious how the protection goes in other places, could even be adapted to areas cleared of lots of weeds like lantana

What an amazing and engaging talk, thanks very much! Unfortunately , I do agree that geosciences have taken a hard hit in tertiary education. I recently completed a Bachelor and there were almost no geoscience subjects. A real disappointment
I think we have no time to achieve the goals are presented in this conference . How is feasible to stop increasing demografic 41:22 In poor counties or against a plenty of religious belief .Like Islamic Religion What about the three millón people currently Lavin in a base of 3 or 4 dollar per day ? . De growth is not gonna happen. They are just surviving currently
Human population reduction by about 95%, carbon capture and no more fossil fuel use or modern medicine or economic growth. Just a massive Senica cliff. PERDICAMENT.
Actually human driven climate change is quite abit faster than the asteroid impact caused.

Give regions aboriginal names. Get rid of European names like :Arnhemsland, Tasmania, Nieuw Zeeland etc..
Human mass on earth = 36% Domesticated land mammal mass = 60% Wild mammal mass on land = 4% 10,000 years ago there were 1500 pounds of wild mammals per human on this planet… in the year 1800 there were 200 pounds of wild mammal per human on this planet… Today there is 5 pounds of wild mammal per human on this planet… This is largely due to human overpopulation… This is ecocide. The number one thing that any one person can do to address the worldwide meta-crisis, is to support a voluntary reduction of the human population. We need a 25% ecological footprint tax for the richest 1% of the world to hire the appropriate medical staff, and set up mobile units that could go to communities around the world, paying people to get sterilized. Organizations, such as the nonprofit#WorldVasectomyDayWouldBeIdeal. When considering, renewable energy options to mitigate the suffering caused by our predicament… Don’t believe the bright green lies! There is nothing renewable about so-called “renewable energy“. “Green energy solutions”, are replaceable at best. The mining, and extractive industries. cause significant ecological damage. Energy powers ecological devastation independent of its source. If human beings actually had an endless source of free clean green energy… Which does not exist it would only fuel the acceleration of the destruction of the biosphere. Deforestation, ocean depletion, habitat loss, over exploitation, desertification, biodiversity loss, soil degradation, groundwater depletion, overpopulation, rampant pollution, and the six mass extinction would all continue to accelerate. This is not a supply problem… It’s a demand problem! Fewer humans equals less suffering for all life on earth! We really need to promote government and nonprofit funded vasectomies and tubal ligations. I realize that it is unlikely that governments will pass a tax on the rich to pay for voluntary sterilization, and you may not be able to contribute, or participate in a nonprofit that funds voluntary sterilization. However, you can discuss with others whether it is ethical to bring a child onto a planet in the midst of ecological overshoot. We can talk about the ways that we can mitigate suffering, or people can stay silent, remain ignorant, live in denial, continue to celebrate procreation, and contribute to the suffering. We can either reduce our population by choice… Or we can let nature do it in her unmerciful way… it’s biology 101… A life that is never brought into existence, is a life that will not have to suffer the unequivocal impending collapse.
Lets see if earth 🌎 can support life without a cryosphere.
The amount of animals we farm is STAGGERING. I am proud to be vegan. Everyone should be forced to be vegan!
You sound like some sort of religious zealot
Thank you very much Dr. Fletcher. Your research is compelling. I am humbled by your efforts to inform Australia of continuing dysfunctional colonial beliefs which are, unfortunately, disguised as science by some very influential intellectuals. It is abundantly clear that Western concepts underpinning separation of humans and "nature" have a striking similarity to "original sin” and have severely compromised objective application of The Scientific Method. I do wonder what we would find if ecological research in Australia were subject to independent statistical replication using complete data sets. Peer review amongst individuals sharing the same beliefs, career paths and international conference presentations, has obviously failed.
It's just dawned on me that the main thrust of climate denial is actually denying The Holocene, the period of unusual climate stability.

Nice work.im actually very surprised photoreceptor replacement is not a common procedure in 2024. Considering they've been making them for years now. Doesnt really seem that complicated with todays technology to use crispr cas9 to edit faulty genes put some cones and rods on a nano honey comb bio degradable scaffle and put it into place.
The official introduction of the term Anthropocene was rejected last week. But not because of a lack of evidence but because nobody agreed with the starting date. 1950 was proposed and not accepted. Because human influence started way earlier. So let's wait for the next proposal.
This'll be an investment metal, just you wait....
Rest in peace, Will. We are forever grateful for your contributions to science and humanity.
