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”

At Risk

Sea Level Rise2 Factors:

Ice MeltingThermal Expansion

Sea Level Rise Video

The Exaggeration:

IPCC (International Panel on Climate Change)

2001 IPCC Projections

Dynamical Ice Flow

Dynamical Ice Flow

Was his statement misleading?

Error 2: Pacific Island “drowning”

Tuvalu

Atoll Formation1. Volcanic Island Forms2. Coral Fringing Reef is

Established3. Island Submerges as it

cools4. Barrier of Coral Appears5. Island Submerges below

sea level leaving only coral island

6. Atoll is formed

Atoll Formation

Cook Islands : Fringing/ Barrier

Cook Island Aitutaki: Atoll

Coral Reefs

Coral Reef Growth Potential 10 X Rate of Sea Level Rise

Maldive Tree

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 CirculationHOW DOES IT MOVE HEAT AROUND THE

EARTH?

Is it stopping?We can’t exclude a disruption or shutdownScientific Consensus is that it will not be

shut down (disruption possible)
