Geoengineering refers to planetary-scale engineering projects
which attempt to influence global properties.
reclamation - the world's oceans represent
ecological wildernesses. The main problem is that all the food sinks to the
bottom - where there is no light and plants cannot grow. Ocean reclamation
aims to fix this problem - by surfacing over the oceans.
- Desert reclamation - some of the world's equatorial
regions have baked. They badly need irrigating on a large scale.
- Tundra reclamation -
the earth is currently in the middle of an ice age - and much of the large
northern landmasses are frozen wastelands. Some geoengineering interventions
aim at improving this situation.
- Irrigation - water supplies are of critical importance
to plant and animal health. Constructing reservoirs by building dams helps
supply fresh water.
- Earthquake amplification via seismic stimulation - amplifying and prolonging small earthquakes can help to avoid big ones.
- Cloud control and the weather - attempts to influence
precipitation may help irrigate the planet in the future, and may have power to
help avert extreme weather conditions.
- Mountain reclamation - some of the planet is too high off
the ground. The air is thin, and plants do not grow well. Mountains cause
clouds to empty themselves - and create dry areas in their "precipitation
shadow". Unfortunately, mountain reclamation looks as though it will be
difficult and expensive.
