global warming, definition of

Global warming is the name given to the theory that there is increase in the average temperature of the Earth surface air and oceans since the mid-20th century and its projected continuation.

The exact mechanism of warming is not precisely understood, although it is strongly suspected that Greenhouse gases are to blame, as increasing concentrations of such gases help trap heat in the atmosphere and so raise mean temperatures.
