Error Analysis

Error 1: Sea Level Rising 6 m sea-level rise of up to 6 m (20 ft) will be caused by melting of either West Antarctica or Greenland

2001 IPCC Projections

Dynamical Ice Flow

Was his statement misleading?

Error 2: Pacific Island drowning

Tuvalu

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

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)
