[Chapter 2: Observations: Atmosphere and Surface] Hartmann et al. 2013http://www.climatechange2013.org/images/report/WG1AR5_Chapter02_FINAL.pdf FAQ 2.1, "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."
Myth vs Facts..... EPA (US) (2013). Arkivita el la originalo je 2011-12-06. Alirita 2016-01-12 .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).
