Security Lifecycle

Land Management

Plant trees & plants to absorb more CO2, reduce tropical deforestation.


Convert waste vegetation - leaves, straw, etc. - into charcoal & bury.


Burn biomass for fuel. Capture the resulting CO2 & bury it.

Policy Enforcement

Separate out industrial CO2 & bury it undergroud in old oil wells.

Paint it White

Paint roofs, roads, & pavements bright white to reflect lots of sunlight.

Monitor & Manage

Use giant towers & artificial trees to scrub pure CO2 from the air.

Enhanced Land Weathering

Accelerate natural CO2 absorption by rocks by adding minerals to soil.

Intrusion Detection

Stir megatonnes of limestone into oceans so more CO2 is absorbed by less acidic waters.

Cloud Whitening

Air-spray particles of sea salt to make clouds whiter & reflect more sunlight.

Security Assessment

Add iron filings to surface water & boost growth of CO2 - absorbing algae.

Stratospheric Aerosols

Scatter sulphate particles high in the atmosphere to reflect sunlight & lower heat.

Threat/Risk Analysis

Launch thousands of orbiting mirrors to divert sunlight away from the surface.

Desert Reflectors

Cover vast areas of unused land with foil. No, seriously.

Security Policy Creation

Fill the atmosphere with terratonnes of soot, dropping temperatures.
