Bottom fishing can release CO₂ from the seabed, but the consequences for the climate are not straightforward. New research, published in the Journal of Applied Ecology, shows that disturbing the seabed sets in motion multiple processes with contrasting effects. The overall climate impact of bottom fishing is the result of these processes and depends strongly on where fishing takes place and on whether carbon is released that would otherwise have remained stored in the seabed for long periods.
