The greenhouse effect warms the Earth by:

• causing an increase in the amount of energy coming from the Sun

• causing the Earth to absorb more energy from the Sun

• preventing infrared radiation from leaving Earth's atmosphere

Warming temperatures cause sea ice to melt. Less sea ice means:

• less energy will be reflected by the ice and temperatures will increase even more.

• more energy will be absorbed by the dark ocean water and temperatures will decrease.

• simply that there is less sea ice; it has no effect on temperature.

How do clouds affect surface temperature?

• Clouds can block incoming energy, causing warmer temperatures.

• Clouds can block outgoing energy, causing warmer temperatures.

• Clouds can block outgoing energy, causing cooler temperatures.

• Clouds can absorb incoming energy, causing warmer temperatures.

This graph demonstrates that:

• Variation in energy from the Sun cannot explain the current increase in global temperature.

• The more energy given off by the Sun, the higher the temperature on Earth.

• As solar radiation decreases, Earth's temperature increases.
