Global uppvärmning är beteckningen på den observerade uppvärmningen av jordens lägre atmosfär och hav sedan 1950-talet samt dess förutspådda fortsättning. Under 1900-talet steg den globala genomsnittstemperaturen med 0,74 ± 0,18 °C. [2] Climate change includes both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

These gases let in light but keep heat from escaping, like the glass walls of a greenhouse, Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.

Since 1906, the global average surface temperature has increased by more than 1.6 degrees Fahrenheit (0.9 degrees Celsius)—even more in A global warming conspiracy theory invokes claims that the scientific consensus on global warming is based on conspiracies to produce manipulated data or suppress dissent.
