Chemical change is the process in which one substance is chemically changed into a different substance. As you breathe at this very moment, your body is continuously reacting simple sugars with oxygen to produce water and carbon dioxide (+energy). The car you drive daily also uses combustion reaction to make octane in conjunction with oxygen to produce water and CO2. Plastics, many clothing material, battery, medicine etc needed to go under chemical changes from its initial reactants for us to enjoy everyday.

Chemicals are omnipresent, so almost any change can be described as a chemical one. If you think of light in terms of a chemical change, it would be the movement of photons, or light particles generated by the energy source (ie. electric current or the burning of gas.)
If you want to describe global warming as a chemical change, you could say that the ozone layer is disappearing because of the amount of chlorofluorocarbons released into the air since the 1930s with industrialization. And global dimming, the pollution caused from vehicular exhaust is keeping us cooler by creating a layer of protective smog from the heat. These changes could potentially destroy life as we know it.
