Abstract:

Ocean acidification and rising ocean temperatures both pose threats to many marine organisms’ physiology and habitats. This paper will establish whether or not these factors have a negative impact on populations of foraminifera, an important type of zooplankton, and if so, to what severity? In addition, this paper promotes the need for more research into the effects of acidification and warming on marine life. While the predicted impacts in reviewed studies varied in severity, they all agreed that ocean acidification, and to a lesser extent ocean temperature rise, will negatively impact foraminifera. Most researchers also agreed that more research must be done to understand the full extent of the impacts of ocean acidification and ocean temperature rise on foraminifera. This paper concludes that the cumulative effect of climate change as a whole be more harmful to foraminifera than any individual factor. Research examining the combined impact of climate change factors such as ocean temperature rise and ocean acidification should be undertaken.
