In the outline below, questions are asked with audience response given. These responses represent one possible answer, but it is expected that the presenter will discuss these questions with guests to help them understand why these answers are correct. The flexibility of the exhibit allows for the presentation to be guest directed. Sample questions are used in the outline but it is expected that each facilitator uses their own knowledge and research to inform the presentation. #> #> **Note: #> - Lines that begin with >> and bracketed text denote presenter instructions. #> - (Q?) denotes discussion questions. #> - "--- (#) Title---" denotes a new dataset (or the return to a previous dataset) #> #> ---(1) Blue Marble--- #> #> All of this was developed by NOAA, who developed the technology called Science on a Sphere. #> - Using data from satellites, as well as land- and sea-based measuring stations, NOAA scientists produce the Earth images you see here. #> #> >>Objective: The Earth's atmosphere is made of Nitrogen, Oxygen, Carbon Dioxide and other gases. CO2 makes up about 0.04% of the total gases in the atmosphere, but has a profound effect on the Earth's temperature. CO2 is a greenhouse gas, which means it traps some of the heat we get from the sun that would otherwise be reflected back into space. #> - (Q?) Take a look at the Earth, what are some of the different things you see? *Land, oceans, and clouds/air #> - Let's talk a little bit about the air, but first everyone take a big, deep breath and hold it, let it our slow. #> - (Q?) What things were in the air you just breathed? *Nitrogen, Oxygen, Carbon Dioxide, etc. #> - (Q?) What part of the air do we need? *Oxygen #> - (Q?) And what do we make more of? *Carbon Dioxide #> - And that is what we are going to focus on for the next few minutes. #> - (Q?) Who can tell me something about CO2? #> - >>Solicit audience responses about CO2, carbon cycle, and climate change. #> - Carbon Dioxide is considered a greenhouse gas which means it allows the earth to hold on to more of the heat we receive from the sun. #> #> ---(2) Nighttime Lights--- #> #> >>Objective: What are the sources of CO2? Most CO2 comes from burning fossil fuels. About 90% of the electricity worldwide is produced by burning fossil fuels. By looking at the pattern of where there are lots of lights visible at night, we can infer where the most electricity is being consumed. #> - (Q?) Here is a different view of the Earth. What do you think we are looking at here? *Lights #> >>Point out different interesting parts of this image like the Nile, N. Korea, Hawaii, major cities and highways, etc. #> - (Q?) Where do you think all those lights come from? *houses, street lights, buildings, cars, cities, etc. #> - (Q?) That's right, and what do all of those things need to work? *Electricity. #> - So we can use this image to tell us which parts of the world use more energy. #> - Compare the eastern half of the US to the western half. Look at China and India. #> - (Q?) There are lots of ways to make electricity, but what do you think is the most common? *Coal #> - About 50% of the electricity in the US and 40% of electricity worldwide is produced by burning coal. #> - (Q?) When you burn coal or other fossil fuels like natural gas, what are some of the byproducts? *CO2, Sulfate, particulate matter #> - The areas where we see more lights use more electricity. If these areas are making their electricity by burning coal they are creating more CO2. #> #> ---(3) Air Traffic--- #> #> >>Objective: Burning fossil fuels for electricity isn't the only source of CO2, transportation is also a major contributor to increased CO2 levels. #> - (Q?) Burning coal isn't the only source of CO2. What are some other sources? *Cars, burning gasoline, airplanes #> - This image shows air traffic patterns over the course of a day. What areas have the most planes coming and going? *N. America, Europe, Pacific Rim. #> #> ---(4) Aerosols: Black Carbon--- #> #> >>Objective: Areas of the world with large electricity demands and transportation patterns emit the most CO2 into the atmosphere. #> - That CO2 doesn't stay in one spot, gases in the atmosphere are mobile, pollution from one country affects the world. #> - The amount of Carbon in the atmosphere can be tracked by satellites. #> - Here the purple areas indicate areas where there are high levels of Carbon in the atmosphere. #> - (Q?) What areas do you see the most? *N. America, China, India #> - What did we see in these areas when we were looking at other images? *Lots of lights and air traffic #> - The areas use a lot of electricity and burn a lot of fuel for transportation. #> #> ---(5) Climate Model: Temperature Change Comparison (GFDL a1b and b1)--- #> [paused] #> #> This dataset is a model. It will show us what happens to temperature as Carbon Dioxide levels increase. #> - This dataset starts in the past and shows real data, and then predicts a future state based on computer simulations. #> - The numbers on the bottom tell us the date and the amount of Carbon Dioxide in the atmosphere. #> - 300 parts per million (ppm) is the same as 0.03 %. #> - (Q?) What do you think the colors represent? *temperature #> - The temperature is adjusted so the average temperature in the year 2000 is represented at yellow. #> - Blue is cooler, red is warmer. [Play dataset. Pause as needed.] #> - What changes did you see? *CO2 increased, and temperatures increased. Temperature increased more over land, especially at the North Pole. #> #> (optional)---(6) Venus: Radar Brightness--- #> #> To see a scene of a runaway greenhouse effect, that is global warming gone out of control, we look to one of our neighbors in the solar system. #> - The planet Venus has an atmosphere that is 96.5% carbon dioxide. #> - Because of all the heat that gets trapped, the average surface temperature of Venus is around 850 degrees Fahrenheit. #> - Our atmosphere is far from having that intensity of carbon dioxide, but we can hold Venus in our heads as an example of what we want to avoid. #> #> ---(7) Blue Marble--- #> #> >>Objective: Global warming is a reality, but we have the power to minimize or even reverse it based on what we do. #> - All is not lost! There are many things that every person in this room can do this week to start to slow the increasing amount of CO2 in the atmosphere. #> - (Q?) What do you think we can all do? *Reduce electricity we use; replace incandescent light bulbs with fluorescents, LEDs; recycle; use less gas by car pooling or taking public transportation; etc. #> - Thanks for seeing this presentation, I hope you enjoyed it, please feel free to stick around to ask any additional questions you may have. #> #> (optional)---(8) Oil Spill: Deep Water Horizon - 2010--- #> #> >>Objective: There are other dangers of relying on fossil fuels. #> - This image shows the extent of the oil in the Gulf of Mexico since the Deepwater Horizon disaster on April 20th, 2010. #> #> #>
