The following outline is provided as an overview of and topical guide to climate engineering:

Geoengineering (also known as climate engineering or climate intervention) is the deliberate large-scale interventions in the Earth’s climate system intended to counteract human-caused climate change. The term commonly encompasses two broad categories: large-scale carbon dioxide removal (CDR) and solar radiation modification (SRM). CDR involves techniques to remove carbon dioxide from the atmosphere and is generally considered a form of climate change mitigation. SRM aims to reduce global warming by reflecting a small portion of sunlight (solar radiation) away from Earth and back into space. Although historically grouped together, these approaches differ substantially in mechanisms, timelines, and risk profiles, and are now typically discussed separately. Some other large-scale engineering proposals—such as interventions to slow the melting of polar and alpine ice—are also sometimes classified as forms of geoengineering.

Climate engineering can be described as all of the following:

• an applied science –
  • a branch of engineering –

• Climate Justice Alliance – Coalition opposing geoengineering as incompatible with climate justice
• NOAA Geoengineering Program – U.S. government agency conducting geoengineering-related research

• Ken Caldeira –
• Paul J. Crutzen –
• John D. Hamaker –
• David Keith (scientist) –
• Klaus Lackner –
• Christopher McKay –
• Nathan Myhrvold –
• Steve Rayner –
• Stephen Salter –
• Stephen Schneider –
