Error Analysis
2
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
3
At Risk
5
Sea Level Rise 2 Factors: Ice Melting Thermal Expansion Sea Level Rise Video
7
The Exaggeration:
8
IPCC (International Panel on Climate Change)
9
2001 IPCC Projections
10
Dynamical Ice Flow
12
Was his statement misleading?
13
Error 2: Pacific Island drowning
14
Tuvalu
15
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
16
Atoll Formation
18
Cook Islands : Fringing/ Barrier
19
Cook Island Aitutaki: Atoll
20
Coral Reefs
23
Coral Reef Growth Potential 10 X Rate of Sea Level Rise
25
Maldive Tree
26
Yes, people have moved…but was Al Gore accurate?
27
Error 3: Thermohaline Circulation stopping
28
Temperature and Salinity Ocean Circulation: Due to differences in density
30
Thermohaline Circulation HOW DOES IT MOVE HEAT AROUND THE EARTH?
31
Is it stopping? We cant exclude a disruption or shutdown Scientific Consensus is that it will not be shut down (disruption possible)
32
Error 4 Carbon Dioxide Driving Temperature
33
CO2 Measurements Mauna Loa (Big Island Hawaii) ICE Cores Antarctica Greenland
34
Ice Cores
35
Vostok Ice Core, Antarctica
36
CO2 Measurements: Keeling Keeling Curve
37
CO2 Measurements Mauna Loa (Big Island Hawaii)
38
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.
39
Satellites and Temperatures
40
Oxygen Ratios dO18/dO16
41
Oxygen Ratios and Temperature
42
120 Year C02 vs. Temp
43
