What is Geoengineering ?'.. Geoengineering is now defined as .." The Deliberate Large Scale manipulation Of The Planetary Enviroment To Counteract Anthropogenic Climate Change" -The Royal Society 2009.".

What is Geoengineering ? "..GeoEngineering and SRM: Using airplanes to spray the sky with toxic metals and particles, intending to block the sun and force climate change while creating unknown consequences."

What is Geoengineering ? "..Fighting pollution by dumping a even more dangerous and toxic pollution in our skys, that just does not make sense to me " - Canadian 11 Year Old

Geoengineering Techniques.There is wide range of proposed Geoengineering techniques. Generally, these can be grouped into two categories: 1.Solar Radiation Management (SRM), and 2.Carbon Dioxide Removal (CDR).

1.Solar Radiation Management (SRM), Solar Geoengineering

SRM techniques aim to reflect a small proportion of the Sun’s energy back into space, counteracting the temperature rise caused by increased levels of greenhouse gases in the atmosphere which absorb energy and raise temperatures. Some proposed techniques include:
  • Albedo enhancement. Increasing the reflectiveness of clouds or the land surface so that more of the Sun’s heat is reflected back into space.
  • Space reflectors. Blocking a small proportion of sunlight before it reaches the Earth.
  • Stratospheric aerosols. Introducing small, reflective particles into the upper atmosphere to reflect some sunlight before it reaches the surface of the Earth.

2.Carbon Dioxide Removal (CDR) or Carbon Geoengineering

CDR techniques aim to remove carbon dioxide from the atmosphere, directly countering the increased greenhouse effect and ocean acidification. These techniques would have to be implemented on a global scale to have a significant impact on carbon dioxide levels in the atmosphere.
