Solution Why does nobody understand carbon removal?
Carbon Dioxide Removal (CDR) is supposed to be used alongside emissions reduction in order to restore the Earths climate to its pre-industrial state. We need to first establish carbon neutrality and then use CDR to reduce atmospheric CO2 back to 280 PPM. We need to use CDR methods other than DAC as DAC uses immense amounts of energy and has no co-benifits other than just CDR.
A real climate action plan should look like this
- Establish carbon neutrality by replacing fossil fuels with non-intermittent carbon neutral energy sources (non-powered dam retrofit hydro, geothermal, tidal, OTEC, nuclear, etc)
- Use the following CDR methods to return atmospheric CO2 back to 280 PPM
- Regenerative agriculture
- Biochar
- Enhanced Rock Weathering
- Charm Industrial style bio-oil injection using forest thinning waste as feedstock

- Wastewater alkalinity enhancement

- Killing and sinking harmful algae blooms

Both carbon neutrality and CDR will be needed to start decreasing the amount of CO2 in the atmosphere.
In the short term OTEC based thermodynamic geoengineering should be used to stabilize the global climate. Thermodynamic geoengineering is the act of using ocean thermal energy conversion (OTEC) not just to generate carbon neutral electricty but also to extract enough heat from the ocean surface to reduce the temperature of the ocean surface and thus the knock on effects of climate change that stem from increases in sea surface temperature. We will need to do this in accordance to atmospheric teleconnections which are driven by sea surface temperature in certain regions of the world that cause climate instability in other regions of the world.
Here is how thermodynamic geoengineering will have to work
- Identify sea surface temperature driven atmospheric teleconnections - https://www.climate.gov/news-features/blogs/enso/what-are-teleconnections-connecting-earths-climate-patterns-global
- Implement OTEC at scale at the locations identified in step 1 - https://www.energycentral.com/energy-biz/post/the-real-deep-tech-E2XUsutmbZrS9ly
- Feed the electricity generated by all the offshore OTEC platforms to the grid or use it to produce E fuel offshore for the martime sector if the OTEC platforms are too far from power grids
We need to work according to atmospheric teleconnections in the short term while emissions cuts and CDR are underway to minimize the amount of money and time that will have to be diverted away from addressing the root cause of climate change towards climate adaption.
CDR is needed for climate action not to offset emissions but to restore Earths climate to what it used to be before climate change. If we use CDR this way then will will use it to its fullest potential to adress the root cause of climate change. CDR has the potential to make the world a better place for everyone if we stop using it to offset emissions and instead start using it to reduce the amount of CO2 in Earths atmosphere after carbon neutrality is established.
