Definition
Geoengineering is the idea of deliberate modification of Earth's environment on a planetary scale. Typically, the term is used to describe proposals to counter the effects of human-induced climate change. However, others have defined it more narrowly as nature-integrated engineering projects. Geoengineering is distinct from large-scale environmental damage and accidental anthropogenic climate change, which are side-effects of human activity, rather than an intended consequence. The global extraction of hydrocarbons from the sub-surface using integrated geoscience and engineering technology has been termed 'petroleum geoengineering' as an activity with global impact. Definitions of the term are not universally accepted. The Oxford English Dictionary defines geoengineering as "the deliberate large-scale manipulation of an environmental process that affects the earth's climate, in an attempt to counteract the effects of global warming."
