Rewind "restore the earth's carbon balance by storing #OrganicCarbon in anoxic water."

Plants are the best option for capturing CO2

"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 Image
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 Image
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."

๐ŸšจNew study reveals a major hidden C sink in the deep ocean: ancient talus breccias - piles of broken basalt formed along seafloor faults - can trap & store COโ‚‚ for tens of millions of years, potentially offsetting a significant share of mid-ocean ridge emissions.

DETAILS๐Ÿงต1/10 Image
2/ Researchers made the discovery while drilling 60-million-year-old seafloor in the South Atlantic.

They found talus breccias containing ~7.5 wt% COโ‚‚ - the highest carbon content ever measured in upper ocean crust, up to *40 times richer than previously sampled basalts. Image
3/ Why so much C?

These breccias form when steep faults at slow-spreading ridges collapse, creating piles of fractured rock with high natural porosity (~19%).

Over millions of yrs, cold seawater circulates thru rubble & precipitates carbonate minerals, trapping dissolved COโ‚‚ Image

๐ŸšจSoil food webs boost carbon retention in farmlands

A new study reveals that simply returning crop residues to fields can supercharge soil food webs, enabling microbes, nematodes & fungi to lock significantly more photosynthetic C into farmland soils.

Details๐Ÿงต1/8 #CarbonSink Image
2/ Researchers from the Institute of Applied Ecology, Chinese Academy of Sciences (CAS), used field trials and ยนยณC isotope tracing to map how carbon fixed by crops travels into soil and through the soil food web.
3/ FINDINGS:

Returning crop residues (stover) emerged as a key driver:

It increased particulate organic carbon (POC) by ~30.96% & mineral-associated organic carbon (MAOC) by ~11.39% compared with plots where stover was removed.

๐ŸšจNew research shows how integrating Direct Air Capture (#DAC) with urea production - paired with COโ‚‚ pricing can slash emissions, reach cost parity with fossil-based urea by 2050 & reshape global fertiliser markets through policies like the EU #CBAM.

DETAILS๐Ÿงต1/9 #CDR Image
2/ What DAC-urea is?

It's urea fertilizer made with COโ‚‚ pulled directly from the air instead of COโ‚‚ from fossil fuels.

Air-captured COโ‚‚ + green ammonia โ†’ urea.

Same fertilizer, but far lower climate impact. Image
3/Study presents a framework combining process modelling, prospective LCA & TEA to compare DAC-urea with conventional fossil-based urea today & under 2050 climate scenarios, including a cross-country assessment of Denmarkโ€™s clean electricity system & Egyptโ€™s more C-intensive grid Image

๐Ÿšจ The Royal Society has published a new briefing today finding that techniques to reflect a small portion of sunlight back into space (#SRM) could help lower global temperatures if deployed worldwide, but cannot replace emissions cuts or fully address climate impacts.

๐Ÿงต1/7 Image
2/ โž The report reviews solar radiation modification (#SRM) approaches, including stratospheric aerosol injection (#SAI) and marine cloud brightening (#MCB), outlining their potential to temporarily reduce warming and associated risks.
3/ โž It notes that SRM would only mask the effects of GHG emissions and would not address issues such as ocean acidification.

๐Ÿšจ๐ŸŒฒ New research reveals that even intact boreal forests, some of the planetโ€™s strongest natural carbon sinks, lose their ability to absorb COโ‚‚ as they age.

Hereโ€™s what the scientists found & why it matters for our climate models๐Ÿงต1/9 #CarbonSink #CarbonRemoval Image
2/ Boreal forests cover vast regions across Canada, Russia, and Scandinavia and store enormous amounts of carbon in trees and soil.

Theyโ€™re often seen as stable, long-term carbon sinks, but this study challenges that assumption with new global-scale data.
3/ Using seven global Net Ecosystem Productivity (NEP) datasets and a high-resolution forest age map, researchers tracked how C uptake changes as forests grow older.

They used a space-for-time substitution method, comparing forests of different ages to infer long-term trends. Image
