=**World** __**Water Levels**__= Water levels are on the rise. **In fact, in recent years, world ocean levels have risen by 2-3 millimeters per year.** As the earth is retaining more heat, so is the Earth's water. As the water gets warmer it expands. The water expands it begins to rise. Polar ice caps are melting as well as ice glaciers which contributes to the issue too.



=__**Ocean Temperatures**__=

Because of these temperatures, what has been the result on hurricanes? **A lot of scientist have come to a conclusion that as the earths heat level rises that the waters temperature will rise causing more hurricanes to appear, and they will keep to get stronger.** **Level 5 hurricanes (the strongest kind) have greatly increased in the past 20 years**. These terrible hurricanes are getting stronger by sea surface temperatures that keep the storm

=__**Hurricanes**__= Between 1924 and 2007, 35 hurricanes were recorded at Category 5 strength. No Category 5 hurricanes were recorded officially before 1924.

=__**Coral Reefs**__= Sea temperatures in many places have increased by almost 1°C over the past 100 years, and are currently increasing at 1–2°C per century. **Coral bleaching occurs when the coral can no longer take the temperature of the water. This issue has contributed to a mass loss of coral around the world.**

__**Possible effects of coral bleaching:**__ Coral bleaching causes a significant loss of coral itself and effects the ocean ecosystem significantly.
