1) "It's not warming." Explain 'Cherry Picking' data in time (is it getting colder or warmer?) or space ("It's so cold in this location this winter") Consider factors other than the temperature record that indicate that the globe is warming How many scientific organizations agree that the Earth is warming? Temperature fluctuations are a natural process. Explain the difference between climate change and natural variation climate variation 2. How do we know it's not the Sun: Sunspots, Milankovitch Cycles, nights warming faster than days, the stratosphere is cooling. How do we know it's not Volcanoes: calculations, the Keeling curve. Three factors can change a planet's temperature: The Sun, the Albedo, and Greenhouse Gases We explained the Sun above, Deforestation is causing land surfaces to become lighter which would cool the Earth, That leaves us with Greenhouse gases. Greenhouse gases do warm air Explain the Greenhouse Effect Explain the CO2 in a bottle experiment The rising CO2 IS from Humans: The timing and the amount add up: we are emitting twice as much CO2 as that being added to the atmosphere (where does the rest go?) It's not from Volcanoes: calculations, the Keeling curve, declining O2 shows that respiration or burning were involved. The steady decline in 14C shows the signature of 14C depleted fossil fuels being added to the atmosphere 3. 2°C can't have an impact" (3.6°F)  Arctic amplification and the Wavy Jet Stream Melting Greenland and arctic Ice and the slowing of the Great Ocean Conveyor Belt Sea Level Rise - use some specifics Provide examples of extreme weather events that are already happening. Coral Reefs 4. here is nothing we can do to solve this problem Compare and contrast the various greenhouse gases and what would need to be done to reduce these emissions. Compare and contrast Carbon incentives, Carbon Tax, and Carbon Fee and Dividend. Discuss the results of  Carbon Footprint.
