Chapter 20: Climate Change
3. This article deals with a regional issue.
4. Coral reefs are extremely important biologically because they are the home to many species. Coral reefs have very high biodiversity. About one in every four marine species live in coral reefs. A recent study of the coral reefs in Japan shows that many of the coral species have migrated over many latitude lines north in the past 80 years. A geographer named Hyroya Yamano has been analyzing maps of coral reefs since the 1930s. His studies have shown that out nine common coral species, four of them had expanded northward and two went as far as went as temperate waters. His studies have also predicted that many more of the coral species will migrate and at a very fast rate in response to the warming waters. Some of the species Yamano was studying migrated as fast as 8.7 miles per year, an average species only migrate .4 miles per year. Too much acidity from high concentrations of carbon dioxide can also weaken coral reefs.
5. This article shows that global warming not only effects terrestrial species but also aquatic environments. A result of the atmosphere heating up, the ocean water also heats up causing changes in the habitats of the aquatic species. It is important that we understand how global warming plays a role all over the world.
