"They naturally extract CO2 from the air and use it as feed. The more CO2 plants absorb, the less CO2 remains trapped in the atmosphere." 2/6
As plants decompose, CO2
is released back to the air
"If left alone, plants are eaten by other organisms and releasing the carbon back to the carbon cycle within months."
3/6
Anoxic conditions slow decomposition
"In anoxic waters, plants decompose extremely slowly, effectively storing the carbon much longer." 4/6
The Black Sea is the ideal location
"It is the largest anoxic body of water on earth, 2km deep, surrounded by fertile lands. The Black Sea is the optimal environment allowing affordable, environmentally safe, gigaton scale #CarbonRemoval in this decade." 5/6
🚨What if we bet too much on future carbon removal tech and it doesn’t deliver?
New study shows that over-relying on #CDR like DACCS & BECCS could let fossil fuel emissions continue longer, delay action, and raise costs later.
Key findings🧵1/9
2/ Many net-zero plans assume large-scale CDR. But techs like direct air capture (DACCS) & bioenergy with CCS (BECCS) are tiny today and scaling them is risky due to land, energy & cost barriers.
3/ Researchers ran 6 scenarios using GCAM:
-Stage 1: Plan for high or low CDR now
-Stage 2: Learn mid-century whether high CDR is actually feasible or not, and then adjust policy or not
They tracked emissions, energy shifts, costs & who bears the burden.
This episode dives into a radical proposal: using a buried nuclear explosion on the seafloor to break up basalt & speed up carbon removal via Enhanced Rock Weathering. The goal? Sequester 30 years of global CO2.

This episode unpacks a preprint by Hosea Olayiwola Patrick drawing lessons from COVID-19 for solar geoengineering.

@InSoilClimate secured its largest funding to date through a €100 million agreement with Key Carbon, accelerating regenerative agriculture and carbon credit generation across Europe.
Canada Nickel partnered with NetCarb to scale mineral carbon sequestration at Crawford. NetCarb's tech could boost CO₂ uptake 10‑fold to 10–15 Mt/year, vs 1.5 Mt via Canada Nickel's proprietary IPT Carbonation.
