Maria Milanović et al. (2025) Successful alien plant species exhibit functional dissimilarity from natives under varied climatic conditions but not under increased nutrient availability. Journal of Vegetation Science 36: e70032. doi.org/10.1111/jvs.70032

Alien and native species increasing in their abundance did not differ in their leaf traits. We found significantly lower specific leaf area (SLA) with an increase in mean annual temperature and lower leaf Potassium with mean annual precipitation. For trait–environment relationships, when compared to native species, successful aliens exhibited an increase in leaf Phosphorus and a decrease in leaf Potassium with an increase in mean annual precipitation. Finally, aliens' SLA decreased in plots with higher mean annual temperatures.

#ClimateChange #Biodiversity #EnergyTransition - Scientists’ warning on fossil fuels - "The evidence is clear that fossil fuels—and the fossil fuel industry and its enablers—are driving a multitude of interlinked crises that jeopardize the breadth and stability of life on Earth. Every stage of the fossil fuel life cycle—extraction, processing, transport, and combustion or conversion to petrochemical products—emits planet-heating greenhouse gases and health-harming pollutants, in addition to causing widespread environmental degradation." - Shaye Wolf, Robert Bullard, Jonathan J Buonocore, Nathan Donley, Trisia Farrelly, John Fleming, David J X González, Naomi Oreskes, William Ripple, Robin Saha, Mary D Willis, Scientists’ warning on fossil fuels, Oxford Open Climate Change, Volume 5, Issue 1, 2025, kgaf011, doi.org/10.1093/oxfclm/kgaf011

Environmental Impact of Gold Mining

Gold mining can bring severe pollution hazards, including:
• Water Pollution – Cyanide & mercury contamination threaten aquatic life & human health.
• Air Pollution – Dust and toxic fumes harm air quality & respiratory health.
• Soil Degradation – Heavy metals like mercury & arsenic poison the land, harming agriculture & wildlife.
• Biodiversity Loss – Destruction of natural habitats leads to extinction of vulnerable species.
• Health Risks – Exposure to toxic chemicals causes neurological damage, cancers, and more.
• Acid Mine Drainage – Harmful acids leak into water systems, causing long-term damage.

A stark reminder: The Cadia gold mine has been convicted of breaching dust limits five times between 2021-2023, with one test showing nearly 6x the allowable dust limit. Newmont Corporation has been fined $350,000 in penalties.

It’s time for stricter regulations and sustainable mining practices!

@ajsadauskas @jaystephens Ta, interesting. I vaguely recall some of that, but your helpful toot defo provided more info than i knew.

I think something like this is why i feel, & tbh remain, so archly cynical... If Straya, & frankly the rest of the world, was genuinely honestly doing all the serious shit needed NOW to decarbonise & ameliorate, then seeking engineering solutions in flood zones like this would be ok. Knowing though that we & most others are totes NOT seriously addressing the crisis, fuels [boom tish] my severe pessimism, coz eg, engineering designs need engineering assumptions [in this case including expected heights & frequency of floods]. Such assumptions necessarily must be predicated on a certain "steady state" belief [plus safety margins thrown in]. That's all fine, IF we had reason to trust such assumptions. I do NOT trust them, simply coz there IS no steady state; humans are continuing to add more & more CO2 & CH4 to Gaia's atmosphere, thus more & more raising the enthalpy, ergo the heating energy, ergo... yada yada.

@feather1952 Paul has mixed feelings, but i don't; i feel quite clear on this. IMO we are federally, governmentally, little more than mega-greenwashing climate-criminals, & absolutely do not deserve to host this. Given ofc my opinion counts for nothing, & we prolly will host it, coz this world just rewards abject shitfuckery, i do hope at least that ALL OS attendees make official public statements vigorously condemning us. This fraudulent govt [& predecessor] deserves excoriating opprobrium, not praise.
