flooding and erosion, salt intrusion and freshwater shortage, and the gradual loss of coastal ecosystems. Extreme weather and natural disasters will also threaten coastal populations and businesses.

Anna Grisham on 09 Nov 11Such climate change will cause disruptions in marine ecosystems as well as populations on land. Salt intrusion taints drinking freshwater and makes it undrinkable. The erosion and the climate changes will hurt the marine life by increasing the salinization of the water and harm temperature-sensitive species. The natural disasters will harm the species by physically disrupting their habitats.

Changes in regional sea temperatures have already lead to shifts in the distribution of plankton. As the main food source in most marine ecosystems, the availability of plankton has knock-on effects for the entire marine food chain and all species, large or small.
-
Since plankton is at the beginning of the food chain, the disruption of its population has repercussions on every level. The ocean is experiencing thermal expansion, which also causes a rise in sea level. The change in the temperatures hurt this marine species.

Higher CO2 levels in the atmosphere are already bringing about a decline in the calcification rate of corals and in the future could pass a threshold where reef building is no longer possible.
-
CO2 levels are definitely increasing in the atmosphere which evidently effects marine life. This CO2 could potentially hurt the development of reefs. CO2 levels are connected to climate change.
