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)
