1️⃣ @1PointFiveCCUS, which is developing the STRATOS DAC plant would sell 27,500 metric tons of DAC CDR credits to @TDBank_US over 4 years. “This is the 4th largest CDR purchase by a financial institution all-time (12th largest purchase overall).”
This🧵centers on“The Ethics of Volcano Geoengineering”paper by @MikeVolc @anderssandberg @laramani14 which explored the ethical aspects of using volcanic eruptions to combat climate change.1/11 agupubs.onlinelibrary.wiley.com/doi/full/10.10…
First, what is volcano geoengineering❓
“It involves intentionally triggering volcanic eruptions to release aerosols into the atm, which can cool the planet by blocking sunlight.”
But is it technically feasible & ethically justifiable? Let's explore the complex landscape⬇️

🚨In a recent study, researchers have uncovered insights that shed light on the potential of #EnhancedRockWeathering. They examined an Icelandic Histic/Gleyic Andosol that has received substantial quantities of basaltic dust for ~3,300yrs.
According to this study, the extended timespan (3300yrs) provides a unique prospect to quantify the rates & long-term consequences of #ERW. The basaltic dust added to the soil has been dissolving continuously since its deposition, fundamentally altering the soil's properties.
