* 1. Based on what you've heard, what is your BEST ESTIMATE of the impact on global climate that humans burning fossil fuel (coal, oil, natural gas) produces?

* 2. Based on what you've heard, what is your BEST ESTIMATE of how long human emissions of carbon dioxide remain in the atmosphere?

* 3. Atmospheric warming provides a total of 59°F to global average surface temperature. From what you've heard, what is your BEST ESTIMATE of the portion of TOTAL atmospheric warming contributed by CO2 emissions from humans burning fossil fuels?

* 4. Over the past 500 million years of geologic evidence, what is your BEST ESTIMATE of the correlation between atmospheric CO2 and global average temperature?

* 5. We frequently hear claims that Arctic Sea ice is thinning and declining each year with the implication that humans burning fossil fuels are responsible. What is your BEST ESTIMATE to the recent state of Arctic Sea Ice?

* 6. We frequently hear that sea levels are rising in response to human impact on global warming. Based on the opinion of the world's leading expert on sea level change, what is the likely extent of sea level rise over the next 100 years?

* 7. Earth's climate is in an interglacial of an ice age cycle (a warm phase lasting about 15,000 to 20,000 years). The current interglacial (Holocene) began more than 11,000 years ago. What is your BEST ESTIMATE of how current global warming since the Little Ice Age bottomed out 400 years ago compares with prior warming episodes of the Holocene interglacial?

* 8. The Anthropogenic (human-caused) Global Warming (AGW) theory claims atmospheric emissions of CO2 produced by humans burning fossil fuels will cause "catastrophic" global warming over the next 100 years. The AGW theory not only predicts, but requires that the tropical atmosphere between 8 km and 12 km above sea level must exhibit a strong "greenhouse" warming signal. The presence of the theorized greenhouse signal would lend credibility to the AGW theory; the absence of the theorized greenhouse warming is sufficient to refute the AGW theory. What is your BEST ESTIMATE of the degree to which this required AGW greenhouse warming signal has been observed?

* 9. A variety of forces can impact global climate change. Solar variability is one. Orbital changes is another. Geologic changes another. Changes in greenhouse gas in the atmosphere is also a candidate for climate change. What is your BEST ESTIMATE of which of the following forces has (by far) the strongest correlation with changes in global climate over the past 1000 years?

* 10. What is the highest level of education you have received?
