Reverse the effects of global warming

Understanding
Global warming is partly caused by the greenhouse effect. The greenhouse effect occurs when "greenhouse" gases such as carbon dioxide and methane are released into the atmosphere in large quantities or when the power reaching earth from the sun varies. Greenhouse gases warm up the planet because they are more absorbant of infrared radiation which reduces the amount of heat from the sun that escapes back out into space. Instead the heat is held in the atmosphere for longer which increases the overall temperature of the planet.

Many human activities involve releasing greenhouse gases into the atmosphere. This contributes to global warming. This is therefore the aspect of global warming that can more easily be changed to achieve the most significant effect on global warming.

Using satellite shades to reduce the amount of light getting to earth would not be as permanent or reliable compared with reducing greenhouse gas concentrations in the atmosphere. It would, however, be a much faster solution. You could set off a large explosion in space to disperse a reflective powder and create a temporary and short lived cloud that reduces the power that reaches earth and earths atmosphere.

Method

 * 1) Reduce carbon emissions.
 * 2) Reduce methane emissions.
 * 3) Reduce the amount of power that reaches the earths atmosphere from the sun.
 * 4) Create a cloud of dust to reflect, absorb or scatter light that would otherwise have reached earth from the sun.
 * 5) Create a system of mirrored or absorbing and retransmitting satallites around the earth.
 * 6) Choose an orbital radius from the sun and speed such that the satellites are always positioned between the earth and the sun so that they block as much light as possible.
