Ocean Iron Fertilisation

Rate this resource

This Catalyst article looks at OIF (Ocean Iron Fertilization) a process of pouring iron into the oceans. The theory behind it is to slow climate change by using a process that already occurs naturally. Nature has a way to draw carbon dioxide (CO2) from the air down into the ocean. If the process could be speeded up, climate change that results from CO2) building up in the atmosphere might be prevented, or so the thinking goes. Many worry that interfering with the Earth’s natural processes has contributed to the climate change mess and has made the situation irreversible. Is this a valuable new way to deal with climate change or reckless tampering with the sea?
