Global warming refers to rise in temperature of the Earth, while climate change refers to the changes that are happening on this planet such as rising sea level, heavier rainstorms, melting of glaciers, increase in frequency of drought, outbreak of infectious diseases etc.
@ Farshad Pazhoh Sir, In simple term, climate change refers to a change in global or regional climate patterns such as erratic rainfall patterns, sudden rise or fall in temperature,etc. Whereas, global warming refers to a gradual increase in temperature of the earth's atmosphere as a result of greenhouse effect i.e. increased levels of different pollutants especially carbon dioxide, CFCs, etc.
