7 Don t Want To pick On Anyone But!
8
9 The Climate System Is Complex The climate system includes the: Atmosphere Hydrosphere Geosphere Biosphere Cryosphere (Ice & Snow)
10 How Is Climate Change Measured Some Techniques Used Short Term (10 s to 100 s of Years) Growth of tree rings Pollen contained in sediment and coral reefs Atmospheric Measurements Ocean Temps Longer Terms (1,000 s to Millions of Years) Drill cores in glacial ice Seafloor Sediments O-18 (warm) in ancient sea shells Which Tells Us The Most About Climate Change?
11 Many Now Believe These Two Critters Are Critical To Understanding Climate Change Foram shells Warm Water = High O 18 Cold Water = Low O 18 Diatoms Eats Up CO2 Produces O2
12 Back To Our Story..Natural Causes of Climate Change Several explanations have been formulated to explain climate change, including: Exposed Land Surface Changes Variations in Earth s orbit eccentricity, obliquity, and precession Volcanic activity Changes in the Sun s output associated with sunspots
13 Changing Land Surface Elevation More Land At Higher Elevations (Mts) Cooler Earth??
14 Orbit & Tilt Changes
15 Effect of Volcanic Activity on Solar Radiation
16 Sun Spots??
17 More Sun Spots Over A Long Time = Warmer Earth??
18 Rock and Continents The Earth s Conveyor Belt! Ridges New Rocks Trenches Old Rocks
19 You See The Earth Changes! In Lots and Lots of Ways!!
20 Future Changes Climates??!!
21 But The Real and Undeniable Climate Tracking Is All About. Glaciers: The Earth s Natural Thermometers!!
22 Let s Look At The Ice & Mud. Deep Sediment Drilling & Core Analysis Ice Cores tell us the Temps! Higher O18 = Warmer Temps
23 What Has Happened Over Time? Guess What Forams Suggest Global Temperatures Have Actually Changed Throughout Time! Snowball Earth-700 MYA! Lasted 80 Million Years!
24 5-6 Giant Ice Ages! Followed By Major Global Warming! 2011 Pearson Education, Inc.
25 Climate Change Anyone?
26 Glaciers Come and Go Global Cooling And Warming!! Just 8-10,000 yrs ago! Chicago, Buffalo, New York Under Ice Sheet
27 Most Recent Glacial Ice!
28 2011 Pearson Education, Inc.
29 Ice Cores tell us the Real Temps! Higher O18 = Warmer Temps Higher O 18 Lower O 18 O18 From Ice and Sea Shells So What Has Happened in 15,000 Years?
30 We Have Been Warming There Is No Denying!
31 2011 Pearson Education, Inc.
32 Two Scenarios Of Change For Global Warming Worse Earth vs Better Earth
33 Today, Fresh From The Ice Ages. 31% of Earth is Non Productive Ice Sheets & Deserts! 2011 Pearson Education, Inc.
34 Warm Earth in Geologic Times Anchorage??
35 Cold Earth = Massive Glaciers--5 Global Mass Extinctions Followed By Warm Earth = Explosion of Life!!! 2011 Pearson Education, Inc.
36 Going From a Colder Earth to A Warmer Earth Change Happens End of Dinosaurs Warm Earth Cold Earth Lowered 125 m = 4500 inches 4500/18000 = 0.25 in/yr!! Today only 0.12 in/yr!!!!
37 Today.The Poles
38 Net Effect: Changes in Arctic Sea Ice
39 Ohh..Glaciers and Diatoms Need Silica to Grow Melting Glaciers Full Of Silica From Rocks Remember What Diatoms Do? Diatoms suck up CO2 Produces O2!!!!
40 Producing Oxygen On Earth Takes in C02 produces O2 60% Atm Oxygen from Diatoms! Must Have Glacial Melting..
41 The Global Energy Dilemma Energy Food Water Being Good Stewards Of The Earth
42 CO 2 Concentrations Over the Past 400,000 Years (Famous Hockey Stick Graph) The Problem..Based mostly on Tree Rings!
43 CO2 vs Temp over Time 26 C = 79 F 15 C = 59 F 20 F Difference!
44 Shhh We Think it Has to do with Volcanos!!
45 Human Influences Remember this Guy? Or This One?
46 Alternative Fueled Vehicles AFV s
47 Hydraulic Fracturing VS Rare Earth s From China 7000 Batteries! May be Hazardous To your Health If You Work in China
48 Rare Earth = Problems!! Air, Water and Land Environmental Disaster!! 1 Ton of Mining of Rare Earths Produces: - 1 Ton Radioactive Waste Liquids - 10,000 M 3 Waste Gas (S, HF etc) - 2,000 Tons of Mine Tailings Source: EWI.ORG, 2016 Google: China, Rare Earths, Leukemia!!
49 Air Pollution Haze from China-Climate Change?
50 Needs Electricity! About 2 Million on World Roads-Project 100 M by % of World s Electricity Comes From???
51
52 Nat Gas to Hydrogen: The Energy End Game One Battery!!!!
53 Warming for 100 years or 10,000 years? Ice Cores-Temps CO2 Tree Ring Studies
54 These Places Know About Change: New Orleans Flooding Fukashima Earthquakes Hawaii Volcanos
55 It s About Change..Right? Temps Changes Over Time O2 Changes Over Time CO2 changes Over Time Species Change Over Time Volcanos Change Over Time Glaciers Change Over Time Our Orbit Changes Over Time The Sun Changes Over Time The Earth Changes Over Time
56 Doesn t Really Mind Change!
57 Not Big On Change!
58 2 Books to Read!!
59 2011 Pearson Education, Inc.

61 It s All About Change Get Used to It!!
62 Dr. Ken Morgan, Director Veronica Merrill, Program Coordinator
63 Global Sellers-Buyers What will the U.S. be by 2030?
64 Update On Importing Fast Lane! OIL IMPORTS--EIA Oct million bbls/day!! OIL EXPORTS (since August) Oil = 1 m bbls/day to 2 m bbls/day!! Refined Products = 6 m bbls/day!! Total = 7.5 m bbls/day! Net Imports: 10-8= 2 m bbls/day!!! WE ARE SELLING EVEN MORE!!!
