«The 2 °C target was all about warming and didn't involve consideration of ocean
acidification in any direct way,» said University of Queensland professor Ove Hoegh - Guldberg, one of the lead authors of the recent Intergovernmental Panel on Climate Change assessment chapter dealing with ocean impacts.
A wide range of human activities affect marine biodiversity both
in direct ways, such as exploitation by fisheries, habitat loss due to dredging, filling, and other construction influences, fishing gear impacts, and pollution, and
in less
direct ways, including effects of global change resulting
in acidification, warmer waters, and coastal inundation.
