Explanation / Answer

1.(b) Aerosols are- microscopic liquid and solid particles in the atmosphere.

2.(b) The maximum extent of the last ice age was- 21,000 years ago.

During Pleistocene the most recent Ice Age occurred. During this time, glaciers covered huge portions of the planet Earth. So, the recent glacial period, which become pronounced about 21,000 years ago.

3.(c) Most all climatic models predicet- a rise in global temperature well into the future.

Climatic models can be described as a numerical portrayals of the associations between atmosphere, seas, land surface, ice and the Sun. According to these models global temperature of the Earth will be increased in the future.

4.(c) As level of Carbon Dioxide increases- so does temperature.

Carbon Dioxide is a greenhouse gas, so the temperature will also rise.Though there is a corelation between Carbon Dioxide and temperature but, reason behind the rising of temperature is not solely or always due to Carbon Dioxide enhancement in the atmosphere. There are also other greenhouse gases present. And temperature is not always increases at the equivalent rate that Carbon Dioxide increases.
