Cumulative impacts on the marine environment

Year: 2008 Author: Hugo Ahlenius, UNEP/GRID-Arendal
Description:
Climate change may, through effects on ocean currents, elevated sea temperatures, coral bleaching, shifts in marine life, ocean acidification and much more severely exacerbate the combined actions of accelerating coastal development, coastal pollution and dead zones, invasive species, bottom trawling and over-harvest. These impacts will be the strongest in 10-15% of the Worlds oceans. These areas, however, are concurrent with the most productive fishing grounds today, responsible for more than half of the marine landings globally.
