Carbon Cycle and Greenhouse Effect

The average temperature of the surface of Earth has increased approximately 1°C in the past century. Which reason best explains this increase in temperature?

• lower levels of ozone in the atmosphere

• lower levels of nitrogen in the atmosphere

• higher levels of carbon dioxide and other greenhouse gases in the atmosphere

• higher levels of oxygen in the atmosphere

What do most scientists agree the issue with burning fossil fuels is?

• Burning the carbon that should be stored underground and putting it in the atmosphere is increasing the greenhouse effect to dangerous levels.

• Burning the carbon that should be stored underground and putting it in the atmosphere is decreasing the positive effects of the greenhouse effect

• Burning fossil fuels is creating too much carbon on Earth

• Burning fossil fuels is using up all all of Earth's carbon
