The Climate Change Authority of #Australia has issued a report that pinpoints #CarbonSequestration as critical to reduce emissions.
"Storing C away from the atm is integral, both to avert #GHGs from entering the atm & to #remove them from it."

The report notes that "while conventional #CarbonAccounting is simple and economically flexible, it does not consider crucial differences between different sources and sinks of #GHG#emissions." As a result, ๐๐ญ ๐ฉ๐ซ๐จ๐ฉ๐จ๐ฌ๐๐ฌ ๐ญ๐ก๐ ๐๐จ๐ฅ๐ฅ๐จ๐ฐ๐ข๐ง๐ ๐๐๐ญ๐ข๐จ๐ง๐ฌ: โฌ๏ธ

5๏ธโฃ "Public investment in #sequestration should leverage co-funding prospects by aligning with areas of non-C benefits & product use.
6๏ธโฃ #CDR should be included as a distinct category in national decarb plans, emissions reporting & the Authorityโs progress reports."

"In order to assess carbon-biodiversity trade-off, the new paper examines the spatial relationships between biophysical & social values for #CarbonSequestration potential (measured as CO2 flux) & #biodiversity in Finland, using integrated valuation."
The approach used by authors "combines methods from #CarbonSequestration modelling, expert scoring approaches to biodiversity assessment and public participation geographic information systems (PPGIS)." 2/6
Results indicate "strong spatial associations between biophysical assessment of #CO2ย #flux and biodiversity priorities, and weaker associations between biophysical and social values." 3/6

"#Geoengineeringโa mechanism to mitigate sea-level riseโhas garnered scientific interest in line with the present state of #ClimateChange. This newly published study investigates traditional+modern SG tech through a systematic literature review."
๐งต1/6
The results suggest that "conventional and pioneering #geoengineering techniques can decrease sea-level rise, and those optimal results would be achieved through the cooperation of methods."ย 2/6
"Ultimately, findings from this review informed five strategies: ๐ธtactical application of conventional #geoengineering; ๐ธoptimisation through technique alignment;
๐ธadaptation to receding coastlines;" 3/6
"This review provides an extensive evaluation of recent advances in multiscale models used for the theoretical physical descriptions of #DirectAirCapture."

"Reviewed (CO2ย mass) transfer works span from theย ab initioย density functional theory calculation relationships toย mesoscaleย Monte Carlo, molecular dynamics simulations & micro-kinetics, adsorption/desorption, & most commonly-investigated specificย macroscaleย concept." #DAC 2/8
The modelled #DAC processes properties reported in the literature have been compared by the authors of this review paper, which allowed them "to identify the most effective sorbents." 3/8
"A comprehensive #bioenergy accounting model with a multi-dimensional analysis was
developed in a new study based in #China by combining spatial, life-cycle, and multi-path analyses."
