| 1189929031 | IPCC - Intergovernmental Panel on Climate Change | Formed in 1988 to evaluate possible future climate changes. | |
| 1189929032 | What are the three major greenhouse gases? | H2O - Water Vapor , CO2 - Carbon Dioxide , and N2O - Nitrous Oxide | |
| 1189929033 | Greenhouse gases are at higher levels than in the past _________ years. | 160,000 | |
| 1189929034 | What gas does cattle and other livestock release into the atmosphere? | CH4 - Methane | |
| 1189929035 | Which country releases more green house gases per person than any other country? | United States | |
| 1189929036 | Hottest century in the past 1000 years is ____ _______. | 20th Century | |
| 1189929037 | Since 1861, how much have the average global temperature risen? | 0.6 - 0.7 Cº | |
| 1189929038 | If floating icebergs melt what will happen to the level of water? | Stays the same, b/c it's already in water. Level will increase only if the land ice melt and come to the water. | |
