Among all geoengineering schemes, those currently considered most feasible involve increasing the planetary albedo, that is, reflecting more sunlight back into space before it can be absorbed. There are a number of different methods that could be used to increase the planet’s reflectivity:
1. Add more small reflecting particles in the upper part of the atmosphere (the stratosphere which is located between 15 and 50 kilometers above the Earth’s surface).
2. Add more clouds in the lower part of the atmosphere (the troposphere)
3. Place various kinds of reflecting objects in space either near the earth or at a stable location between the earth and the sun.
4. Change large portions of the planet’s land cover from things that are dark (absorbing) such as trees to things that are light (reflecting) such as open snowcover or grasses.
