  Climate - Wikipedia, the free encyclopedia
Climate in a narrow sense is usually defined as the “average weather”, or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years.
When the original conception of climate as a long-term average came to be considered, perhaps towards the end of the 19th century, the idea of climate change was not current, and a 30 year average seemed reasonable (note 1).
Climate indices are generally identified or devised with the twin objectives of simplicity and completeness, and each typically represents the status and timing of the climate factor they represent.

As opposed to weather, the short-term conditions that prevail in earth's atmosphere, the climate is the long-term (30 year) average state of weather conditions.
The Earth's temperature is maintained within a range hospitable to life as the result of a naturally occurring phenomenon called the "greenhouse effect." The greenhouse effect is a natural warming of the Earth's surface that occurs because some gases in the atmosphere block the transmission of infrared radiation (or heat).
