Climate: The average daily and seasonal weather conditions of a region, observed over a series of decades.

Weather: The state of the atmosphere at a specific time, i.e. short-term or instantaneous atmospheric variations.

Climate change: A long-term shift in weather conditions, including temperature, precipitation and winds. This may vary from region to region. The change may be due to natural (e.g. El Niño) or human-induced causes (e.g. pollution).

Global warming: An increase in the global average surface temperature. Some areas of the world will warm more than the global average while others will warm less. Global warming is an indicator of climate change.
