Global wairmin

Lowp tae: navigation, rake
Global mean surface-temperatur chynge frae 1880 tae 2016, relative tae the 1951–1980 mean. The black line is the global annual mean an the reid line is the five-year lowess smuith. The blue uncertainty bars shaw a 95% confidence interval.

Global wairming an climate chynge are terms for the observed century-scale rise in the average temperatur o the Yird's climate seetem an its relatit effects.[1][2] Multiple lines o scienteefic evidence shaw that the climate seestem is wairmin.[3][4][5] Mony o the observed chynges syne the 1950s are unprecedentit ower tens tae thoosands o years.[6]

"Evidence for a warming world comes from multiple independent climate indicators, from high up in the atmosphere to the depths of the oceans. They include changes in surface, atmospheric and oceanic temperatures; glaciers; snow cover; sea ice; sea level and atmospheric water vapour. Scientists from all over the world have independently verified this evidence many times."

EPA (US). 2013. The U.S. Global Change Research Program, the National Academy of Sciences, and the Intergovernmental Panel on Climate Change (IPCC) have each independently concluded that warming of the climate system in recent decades is 'unequivocal'. This conclusion is not drawn from any one source of data but is based on multiple lines of evidence, including three worldwide temperature datasets showing nearly identical warming trends as well as numerous other independent indicators of global warming (e.g., rising sea levels, shrinking Arctic sea ice).
