Preventation

Reducing atmospheric levels of the GH-gas CO2, starting with fairly innocuous schemes like planting tree farms to fertilizing the Southern Oceans by adding missing micro-nutrients (an idea much favored by the late oceanographer Roger Revelle) – all the way to full-scale engineering proposals that involve the direct removal of ambient CO2, with subsequent underground sequestration – a vastly more expensive undertaking of dubious technical feasibility.

The other favored approach would try to increase Earth’s albedo to reduce the amounts of solar energy reaching the surface. In analogy with volcanic eruptions, reflective aerosols would be injected into the stratosphere – a costly and unproven scheme, likely to constitute an environmental hazard to stratospheric ozone.
