Geoengineering
Geoengineering refers to deliberate, large-scale interventions in the Earth's natural systems, often intended to mitigate the impacts of climate change or counteract some of its effects. It encompasses a wide range of proposed techniques and technologies aimed at directly influencing the Earth's climate. The mind map will delve into the concept of geoengineering, mapping out the various approaches and technologies used to intentionally manipulate the Earth's climate and environment.

- Hatshepsut's reign
This fishbone diagram clearly presents the key elements during Hatshepsut's reign, including her coronation after seven years of regent rule, education in scholarly and military training, and other significant events. Under each theme, multiple levels are further developed, possibly detailing the impact of political decisions, the expansion of diplomatic relations, contributions to cultural achievements, etc., offering an in-depth perspective for understanding the rule of the Egyptian queen.

Geoengineering
Carbon dioxide removal (CDR)
Carbon sequestration
Removing CD (carbon dioxide) from atmosphere and capturing as solid, liquid, or compressed gas
Geological sequestration
gas passes through column of liquid solvents, which absorb CO2
CO2 passes through pipe to store underground
Reforestation
Direct air capture and storage
Land use management
Biochar
Physical
aeration
Water-holding capacity
nutrient retention
Biological
houses benefitial microbiology
Chemical
cation exchange- more nutrients in soil
does not degrade, is permanent
High in carbon- prevents CO2 from being released
Removal of other green house gasses
methane
nitrous oxide
CO2
ozone-depleting halocarbons (chemicals with one or more halogens)
Quicker than removing CO2
Carbon dioxide capture
Trapping CO2 at emission source, transport to storage location and then isolating it
blocks CO2 entering atmosphere
mostly used to capture emissions from industrial processes
Pre combustion capture before burning
Post combustion- after burning
Safe, but slow and expensive
Oxyfuel combustion- burning fuel with oxygen
Higher flame temp than air fuel flame
generates flue gas with high concentration of CO2 and water vapour
possible to separates CO2 with low temp dehydration and desulfurization processes
Enhanced weathering
Removes CO2 by spreading many ground rock materials onto extensive land or sea
Minerals can absorb CO2
Hurries this process up
still theorical
Biomass
Organic materials as energy source
Carbon neutral
If managed properly, biomass is replenished with newgrowth as it is harvested
Ocean upwelling
Wind blows across water
Bad upper water replaced with good lower water
natural, no human intervention
Ocean fertilization
Add nutrients to surface water level to stimulate photosynthesis from phyplanktons
Nutrients: iron, phosphate, nitrogen
During photosynthesis CO2 drawn from atmosphere
When phyplankton die, they sink and take CO2 with them
Some sank materials will emerge due to ocean upwelling. Carbon turn into sedimentary rock
Ineffective, medium cost, slow, not very safe (undesirable ecological effects)
Sunlight management
Stratospheric aerosols
Terms
Solar radiation
Radiation from sun
Can be captured and turned into energy
Albedo
Amount of light reflected from surface
Used to measure amount of light reflected of celestial objects
Measured 0-1 scale
Earth- 0.3. Earth reflects 30 percent of light that shines on it
Moon- 0.12. Reflects 12 percent
Dark surface low albedo, light surface high albedo
Ice-albedo feedback
Change in area of ice cap, glacier and sea ice changes albedo and surface temp of planet
positive feedback climate process
More ice melts, more heat stored in melted ice
Radiative forcing
Measures change in energy balance caused by change in forcing agent
Greenhouse gasses absorbs solar radiation and surface albedo, increasing temp
Mt Pinatubo
active stratovolcano in Phillipines
Largest eruption in world 100 years ago
Injected 15 million tons of sulfur dioxide into stratosphere, cooled the Earth for 3 years
Arctic methane release
Release of methane from seas and soils in permafrost (long-frozen) regions of the Arctic
Methane causes global warming
Method
Marine cloud brightening
proposed by John Latham
Changes albedo and longevity of clouds
Sprays sea-water into clouds
Some crystals from seawater forms fogs and makes clouds brighter
Desert reflectors
Proposed theory
Cover deserts with reflective polyethylene-aluminum surface to make them more relfective
Not very useful, expensive, quick, large ecological changes
Cool roof
Roof that reflects sunlight and absorbs less solar energy
Everyone would need to do it in order for it to be effective
Sun shield
Huge mirror in space that reflects sunlight away from Earth
Stratospheric aerosol
Injecting aerosol into stratosphere to reflect sunlight back into space
Aerosols- sulfur dioxide, carbonyl sulfide, sulfuric acid. Their particles can reflect
Cloud seeding- adding substances into clouds to cause precipitation
Glaciogenic
mostly uses silver iodide
Causes snow
Hygroscopic
Enhance rainfall
uses salt nuclei or highly concentrated salt solution
Fog harps
Mesh or wire used collect fog
Could actually work
Bioprecipitation
Inject plant pathogens that causes rain into clouds
Proposed by David Sands in 1982
Cloudbusting
Focus cloudbuster in an area that has high orgone, absorbpoint into sky to create clouds.
Geoengineering version of Tai Chi
Pseudoscience
Hail cannon
Shockwave generator that disrupts formation of hailstones in the atmosphere
Not proven to work
