Global Climate Change 1. A layer of Earth at night slowing the rate of cooling. acts as a thermal blanket for the Earth by reflecting heat back to 2. The greenhouse effect is a (natural /manmade) warming of Earth's (lower/upper) atmosphere &i surface. 3. The (greenhouse/enhanced greenhouse) effect is the strengthening of the greenhouse effect through human activities. 4. (EI Niño/La Niña) every 2-7 years heating up the eastern Pacific around the equator. Storms can be (more/less) violent and some areas have extreme drought.
