Geoengineering, Some Potential Quick Fixes for Global Warming?

What might we humans do with geoengineering to fix global warming as quickly as possible? Here are a few ideas:

1. Afforestation: Planting large numbers of trees to increase carbon sequestration.
2. Ocean fertilization: Adding nutrients to the ocean to stimulate phytoplankton growth and increase carbon absorption.
3. Biochar production: Converting biomass into charcoal and burying it to lock carbon in the soil.
4. Cloud brightening: Spraying seawater into the atmosphere to enhance cloud reflectivity and cool the planet. Spraying sea salt particles into marine clouds to increase their reflectivity.
5. Space mirrors: Deploying large reflective mirrors in space to reflect sunlight away from Earth.
6. Carbon capture and storage (CCS): Capturing carbon dioxide emissions from power plants and industrial facilities and storing it underground.
7. Enhanced weathering: Accelerating the natural process of rock weathering to absorb carbon dioxide from the atmosphere.
8. Artificial trees: Engineering devices that absorb carbon dioxide directly from the air.
9. Reflective roofs and pavements: Using materials with high reflectivity to reduce urban heat islands and cool the planet.
10. Solar radiation management (SRM): Injecting aerosols into the stratosphere to reflect sunlight and reduce global temperatures.
11. Microalgae cultivation: Growing microalgae to absorb carbon dioxide and use it for biofuel production.
12. Ocean alkalinity enhancement: Adding alkaline substances to seawater to increase its ability to absorb carbon dioxide.
13. White roofs on buildings: Painting rooftops with reflective coatings to decrease heat absorption.
14. Direct air capture: Using large-scale machines to extract carbon dioxide from ambient air and store it.
15. Floating wind turbines: Harnessing wind energy offshore to generate electricity without emitting greenhouse gases.
16. Soil carbon sequestration: Utilizing agricultural practices and land management techniques to increase carbon storage in soil.
17. Removing black carbon emissions: Reducing emissions from incomplete combustion processes like burning coal and diesel fuel.
18. Methane capture: Capturing methane emissions from landfills, livestock, and fossil fuel extraction.
19. High-altitude nuclear explosions: Detonating nuclear bombs in the stratosphere to create a temporary layer of dust, reducing sunlight and cooling the planet.
20. Carbon mineralization: Accelerating the natural process of converting carbon dioxide into stable minerals through chemical reactions.
21. Enhanced phytoplankton growth: Introducing iron or other nutrients into the ocean to promote phytoplankton growth and carbon absorption.
22. Ocean upwelling: Pumping nutrient-rich water from the deep ocean to the surface to enhance the growth of marine plants.
23. Carbon farming: Implementing farming techniques that increase carbon storage in agricultural soils.
24. Urban forestry: Increasing the number of trees and green spaces in urban areas to cool the environment and reduce carbon dioxide levels.
