Climate Change Song 1. Why is this the greatest science song you have ever heard? ( It's not, is not an acceptable answer!) 2. What was the overall message the song was trying to get across to its viewers? Pizza Debate Video 1. Do you think the data presented about how Pepperoni pizza is the best, is reliable? 2. How can asking questions / clarifying evidence help? 3. Did the speaker seem biased? Yes 4. How do you know? No Bill Nye Debate Video 1. Marc Morano stated that there are periods in our past (Roman and Medieval warming periods) where the temperature was warmer than todays temperature. He used this as an argument AGAINST global warming. Bill Nye followed that up by stating that the warming period Marc referenced only occurred in Europe and wasn t global. How does this clarification of the evidence change how the data is understood? 2. Why is it important to look at both sides of an argument? 3. Why is it important to determine a person's bias before believing 100% of their side? 2
Global Warming Notes Global Warming Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans. Believed to be permanently changing the Earth s climate. Still Debated At least 97% of scientists agree that humans actively contribute to the climate warming trends Not every individual uses every piece of data Not everyone believes humans are to blame Many believe that weather changes (ex. snow) contradict that the Earth is warming Steps you should take with any debated topic Attempt to clarify evidence / find more evidence Clarifying evidence Provides you with more information about the topic Allows you to identify bias Pizza Example Climate Change Example Evidence Pepperoni pizza is the most popular pizza topping. There hasn t been any global warming since 1997. Clarifying Questions Is it the most popular topping everywhere in the world? Is it the most popular topping among every age group? How many individuals were surveyed? Recognize bias Most articles are written for a purpose. Identifying bias will allow you to get a clear view of the topic Steps for recognizing bias Identify the source / author Certain sources have a reputation Fox News Conservative New York Times Liberal Identify the overall tone Locate any over generalizations Everybody knows All sensible people Identify exaggerations Examine your own data Look at the raw data or focus on analyzing graphs Steps for analyzing graphs Read the title or caption Read the x and y axis labels Identify and analyze a key 3 Are you looking at all of the data? Is our global temperature now warmer than 100 years ago? 1,000 years ago?
Look for trends within the data Evidence of Global Climate Change ** Evidence collected from NASA Sea level rising Rose 6.7 inches in the last century Global Temperature Rise The 20 warmest years have occurred since 1981 Warming Oceans Warmed 0.302 since 1969 Shrinking Ice Sheets Between 2002 and 2005 Greenland Ice Sheet lost 36-60 cubic miles Antarctica lost 36 cubic miles of ice Extreme Events Increased Rainfall Ocean Acidification Acidity has increased 30% since the Industrial Revolution What happens if we don t change and continue polluting / burning fossil fuels CO₂ levels will increase Infrared radiation levels will increase Global temperatures will continue to rise Impact of Increased Temperatures Chain reaction because air temperature affects the oceans, weather patterns, snow and ice cover, plants and animals Agriculture Could make it too hot to grow certain crops Droughts can reduce the amount of water available for irrigation If the global temperatures rises 3.6 the US corn production is expected to decrease by 10 30 percent! Energy Less water = Less hydropower = Less energy = Power shortages and blackouts Water Supplies Increased droughts which can impact the water we have available in our homes Health Heat Waves kill people every year They cause more deaths in the US than hurricanes, tornadoes, floods and earthquakes combined Ecosystems / Plants and Animals ¼ of all plants and animals could become extinct within 100 years if temperatures continue to increase Forests Increased wildfires Dry conditions allow fires to start more easily and spread faster If Earth gets 3.6 warmer we can expect fires to burn 4x s more land than they do now 4
Graph Analysis Link 1 What does the x-axis represent? What does the y-axis represent? How much CO₂ was in our atmosphere in 1950? How much CO₂ is in our atmosphere now? What does the graph tell you about CO₂ concentrations over the last 400,000 years? Link 2 If you looked at the data from 1990 to 1992, would you believe in global warming? Why? Why is it important to look at more data? Link 3 What is this graph telling you? How has the sea level changed over time? Link 4 Looking at the X and Y axes, what is the data on the graph going to tell you? Does ocean temperature impact hurricane strength? How do you know? 5
Overall If you compare all of the data you analyzed in this activity, what conclusion can you draw. Include the following Change in CO₂ Change in Ocean Temperature Change in Sea Level Hurricane Strength 6
