“📉 KEY FINDINGS
• At +4 °C, only ~18,000 glaciers remain worldwide by 2100
• At +1.5 °C, ~100,000 glaciers survive
• [They] identif[ed] “Peak Glacier Extinction”:
– ~2041 at +1.5 °C (~2,000 glaciers lost per year)
– ~2055 at +4 °C (~4,000 glaciers lost per year)
🏔️ THE ALPS
• At +2.7 °C, only ~110 glaciers remain by 2100.
• At +4 °C, this drops to just ~20.
Can you imagine the Alps with almost no glaciers left?...”

Estimating Increased Transient Water Storage With Increases In Beaver Dam Activity

“Dam building by beaver (Castor spp.) slows water movement through montane valleys, increasing transient water storage and the diversity of residence times. In some cases, water storage created by beaver dam construction is correlated to changes in streamflow magnitude and timing. However, the total amount of additional surface and groundwater storage that beaver dams may create (and, thus, their maximum potential impact on streamflow) has not been contextualized in the water balance of larger river basins..."

#Australia: Research shows #NativePlants can detox #PFAS-contaminated #water
New research from Australia's national science agency #CSIRO, the #UniversityOfSouthAustralia and the #UniversityOfWesternAustralia has found that PFAS chemicals can be removed from contaminated water using Australian plants grown in a floating #wetland.
May 4, 2022
"They’re the non-stick on #Teflon cookware, the stain resistance in #Scotchgard, and the suppression factor in #FirefightingFoam, but while the staying power of PFAS chemicals was once revered, it’s now infamous as PFAS substances continue to infiltrate the #environment and affect human health.
"Now, new research from the University of South Australia is helping to remediate the ‘indestructible’ PFASs as scientists show that Australian native plants can significantly remediate PFAS pollutants through floating wetlands to create healthier environments for all.
"Conducted in partnership with CSIRO and the University of Western Australia, the research found that PFAS chemicals (per- and poly-fluoroalkyl substances) can be removed from contaminated water via Australian #NativeRushes - #PhragmitesAustralis, #BaumeaArticulata, and #JuncusKraussii.
"Phragmites australis, otherwise known as the #CommonReed, removed legacy PFAS contaminants by 42-53 per cent from contaminated surface water (level: 10 µg/L).
"According to the US Environmental Protection Agency, exposure to PFAS may lead to a range of health issues including a decline in fertility, developmental delays in children, increased risk of some cancers, a reduced immune system, higher cholesterol, and risk of obesity.
"UniSA and CSIRO researcher Dr John Awad says that this research could alleviate many of these environmental and health risks by providing a clean, green, and cost-effective method to remove PFAS from the environment.
" 'PFASs are often referred to as ‘forever chemicals’ because they don’t break down, instead accumulating in the environment and in our bodies where they can cause adverse health effects,' Dr Awad says.
" 'In Australia, PFAS concerns often relate to the use of firefighting foam – especially legacy firefighting foam – which accumulates in the #SurfaceWater of our #waterways.
" 'Our research tested the effectiveness of Australian rushes to remove #PFASChemicals from #stormwater, finding that Phragmites australis was the most effective at absorbing chemicals through its roots and shoots.'
"The study used constructed floating wetlands as a mechanism for plants to grow #hydroponically. Dr Awad says floating wetlands present a novel and flexible way for natural #remediation systems.
" 'Constructed floating wetlands can be readily installed into existing urban environments, such as holding reservoirs and retention basins, making them highly manoeuvrable and adaptable to local waterways,' Dr Awad says.
" 'Plus, as this innovative water treatment system does not require pumping or the ongoing addition of #chemicals, it is a #CostEffective remediation system for PFAS removal.
" 'Add native plants to the mix and we have delivered a truly clean, green and environmentally-friendly method for removing toxic PFAS chemicals from contaminated water.' "
Notes to editors:
- So far, the floating wetlands system has only been examined under control laboratory conditions for PFAS remediation and the research team is looking forward to testing it in the real world, under natural conditions.
- This research is being carried out at the UniSA Mawson Lakes campus. PFAS has not been detected in or around Mawson lakes."
