Changing the amount of heat: Milankovitch cycle (earth’s tilt), sun spots
Atmosphere and Ocean - 6 What could happened if the earth’s average temperature increases a little in a short time? melting ice; less land; less food; more rain; flooding; economy – energy, fuel;
animal extinctions?
Adding extra gases such as CO2, ozone, methane, and CFC’s from car exhaust fumes and factory emissions increases the amount of trapped energy in the troposphere. Global warming, sometimes called the enhanced greenhouse effect, refers to the increase in global average temperature potentially due to human activity. A rise in global temperatures could mean higher sea levels, less land, different vegetation - direct impact on human civilization.
