Global warming is the long-term rise in the average temperature of the Earth's climate system. It is a major aspect of climate change, and has been demonstrated by the instrumental temperature record which shows global warming of around 1 °C since the pre-industrial period, although the bulk of this (0.9 °C) has occurred since 1970. The term commonly refers to the mainly human-caused observed warming since pre-industrial times and the projected further warming.

In the most general sense, global warming is used to refer to a gradual increase in the average temperature of the Earth. This is usually quantified as an increase in the average global surface temperature, which has risen by about 0.6–0.9 °C (about 1–2 °F) since pre-industrial times, with about two thirds of the increase occurring since 1980. It is projected to continue to rise at a similar rate during the 21st century. A wide range of future climate change scenarios have been produced to help guide policy and decision making.

The causes of global warming include a variety of natural and anthropogenic factors. Greenhouse gases in the Earth's atmosphere trap energy from the Sun. This trapped energy makes the Earth's atmosphere warm, and disturbs the Earth's climate. It is not just the Earth’s temperature that we must worry about in the near future. Climate change has the potential to cause various types of disasters, including hurricanes, famine, drought, and displacement of species. Climate change has the potential to cause all sorts of other risks as well, and it threatens both public health and national security. We must take action now to mitigate the effects of climate change and adapt to the changes that are already underway.
