You could call these questions about Anthropogenic Global Warming, if you wanted to impress your professor.
1. Where do you take the global temperature? (temperature will vary by latitude. It is generally hotter at the equator and cooler at the poles)
2. If the answer to #1 is that we take average readings, what would be the effect of several thousand stations in the colder latitudes not reporting?
3. Assuming we can answer number 1, what time of day should we take the temperature? (Global cooling occurs at night, doesn’t it?)
4. Assuming we can answer both 1 and 3, what should the temperature be? (If the current temperature is below the ideal, then Global Warming is a good thing.)
6. Has the planet ever been warmer than it is now? What was that like?
7. Are there generally more weather-related deaths due to cold weather or due to hot weather?
8. Do plants, on average, grow better in cold weather or in warm weather?
9. When you say “Greenhouse gases” what exactly do you mean? Can you name the specific gases?
10. What portion of greenhouse gases does NOT contain carbon?
