'''Global warming''' is an increase in average air temperature in the [[Earth]]'s atmosphere. In the modern period of global warming, a slight increase of {{temperature|0.8|1.4}} has been measured at weather stations throughout the world, since around 1850, when organized records began to be kept.

As far back as temperature records can be reconstructed, periods of global warming and global cooling have alternated; see [[ice age]]s and [[interglacial warming]].

In the modern period of global warming, a slight increase of {{temperature|0.8|1.4}} has been measured at weather stations throughout the world, since around 1850, when organized records began to be kept. Since this happens to correlate with increases in [[carbon dioxide]], it's natural to speculate about what sort of cause and effect relationship they may have.
