1 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

4

5 Sea Level Rise 2 Factors: Ice Melting Thermal Expansion Sea Level Rise Video

6

7 The Exaggeration:

8 IPCC (International Panel on Climate Change)

9 2001 IPCC Projections

10 Dynamical Ice Flow

11

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

17

18 Cook Islands : Fringing/ Barrier

19 Cook Island Aitutaki: Atoll

20 Coral Reefs

21

22

23 Coral Reef Growth Potential 10 X Rate of Sea Level Rise

24

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

29

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

43 400,000 Years C02 vs. Temp.

44 More Recent Data

45 What do you think?
