Climate change is caused by factors such as plate tectonics, variations in solar radiation received by the earth, biotic processes, and volcanic eruptions. Causes of climate change related to human activities are often referred to as “global warming.”

Past and future climate developments are analyzed by using observations and theoretical models. Models based on the physical sciences are often used in theoretical approaches to match past climate ...
