Ocean fertilization: time to move on

摘要

In the face of seemingly accelerating climate change, some have proposed tackling the problem with geoengineering: intentionally altering the planet's physical or biological systems to counteract global warming. One such strategy - fertilizing the oceans with iron to stimulate phytoplankton blooms, absorb carbon dioxide from the atmosphere and export carbon to the deep sea - should be abandoned.rnIt is already commonly accepted that ocean iron fertilization should not be rushed into as a mitigation strategy. The Intergovernmental Panel on Climate Change regards it as supported by neither appropriate assessment of environmental side effects nor a clear institutional framework for implementation.
