Are You a Global Warming Guru? Quiz

1. The factors contributing to global warming, such as the burning of fossil fuels, have been around for countless years. But proper evidence of the trend of warming temperatures dates back only to the year when temperature instrumentation became very accurate and reliable. What year was this?

2. Despite all of the evidence backing climate change, a recent poll found that a staggering number of Republican candidates don't believe it exists. According to the survey, how many out of seven GOP candidates denied the existence of global warming?

3. The Northern Hemisphere's temperature increase in the 20th Century was the largest over a long time. How long?

4. Climate change is responsible for significant increases in annual temperatures. Which year was the hottest of the past century?

5. One of the consequences of climate change is a reduction of snow cover in Arctic regions. Since the 1960s, how much has snow cover in the Northern Hemisphere decreased?

6. And while melting snow may not seem like that big of a deal, Arctic ice is melting as well. Scientists have noted distinct reductions in Arctic sea-ice since at least the 1950s; by about how much has the extent of sea ice declined since then?

7. Melting snow and ice caps translates into rising sea levels, which threaten coastal development. During the 20th century, up to how much did the global sea level rise?

8. Rising sea levels could significantly impact cities and towns located along the water. If the present trends continue, how much of the world's coastal wetlands could be converted to water by 2080?

9. Another impact of altered sea levels is the incidence of, and damage caused by, flooding. According to FEMA, just a one foot increase in sea level could increase annual flood damages up to what percent?

10. In the United States alone, there is about 5,000 square miles of land within two feet of high tide. If sea level increased by two feet, how much land would be eliminated? (Hint: the area is the size of Delaware and Massachusetts combined)

11. Which 19th century event spurred an unprecedented climb in atmospheric carbon dioxide concentrations?

12. Atmospheric concentrations of carbon dioxide are currently higher than they have been at any time in the past 400,000 years, due to a drastic increase recently. By what percent have carbon dioxide concentrations increased since the 1800s?

13. The coasts of the contiguous United States – areas most threatened by rising ocean levels due to climate change - account for 17 percent of the nation's total continental land mass. How much of the US population resides in these areas?

14. Approximately how many Americans reside in the threatened coastal areas?
