Global warming

Global warming is the observed increase in the average temperature of the Earth`s atmosphere and oceans in recent decades. The Earth`s average near-surface atmospheric temperature rose 0.6 ± 0.2 degrees Celsius (1.1 ± 0.4 degrees Fahrenheit) in the 20th century.
The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities".
The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect.
An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.

Only a small minority of scientists discount the role that humanity`s actions have played in recent warming [see Alternative Theories below].


Causes

The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and ......................................
