Atoll Formation 1. Volcanic Island Forms 2. Coral Fringing Reef is Established 3. Island Submerges as it cools 4. Barrier of Coral Appears 5. Island Submerges below sea level leaving only coral island 6. Atoll is formed
Cook Islands : Fringing/ Barrier
Cook Island Aitutaki: Atoll
Coral Reef Growth Potential 10 X Rate of Sea Level Rise
Yes, people have moved…but was Al Gore accurate?
Error 3: Thermohaline Circulation stopping
Temperature and Salinity Ocean Circulation: Due to differences in density
Thermohaline Circulation HOW DOES IT MOVE HEAT AROUND THE EARTH?
Is it stopping? We cant exclude a disruption or shutdown Scientific Consensus is that it will not be shut down (disruption possible)

Temperature Measurements Satellites Ratios of Isotopes The 18 O/ 16 O ratio provides a record of ancient water temperature. (Ocean Sediments) The 18 O/ 16 O ratio provides a record of ancient temperature in ice too.
