Global warmingGlobal warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.[1][2]

Multiple lines of scientific evidence show that the climate system is warming.[3][4][5] Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid-19th century, and in paleoclimate proxy records covering thousands of years.[6]


In the period from 1880 to 2012, the global average (land and ocean) surface temperature has increased by 0.85 [0.65 to 1.06] °C, multiple independently produced datasets confirm.[26] In the period from 1906 to 2005, Earth's average surface temperature rose by 0.74±0.18 °C. The rate of warming almost doubled in the last half of that period (0.13±0.03 °C per decade, against 0.07±0.02 °C per decade).[27]
