Realistic estimates show that global warming can only be kept below 1.5 or two degrees Celsius if carbon dioxide is actively removed from the atmosphere. Storage beneath the seafloor is an option that has been investigated intensively by an international team of scientists led by the GEOMAR Helmholtz Centre for Ocean Research Kiel. An assessment of opportunities and risks has now been published in the journal International Journal of Greenhouse Gas Control.
