Global Variability in Multi‐Century Ground Warming Inferred From Geothermal Data
Résumé
Measurements of Earth's surface air temperatures covering the last 150 years show a pronounced warming (I. Harris et al., 2014) that is largely the result of human influence (Bindoff et al., 2013; Hegerl et al., 2019). Longer records of surface temperature are invaluable for placing the recent anthropogenically perturbed period in the broader context of Earth's pre-industrial climate variability (Neukom et al., 2019). The instrumental surface air temperature record is limited in the years before CE 1850 (Benestad et al., 2019; I. Harris et al., 2014; Morice et al., 2012) and only a few longer instrumental records are available from historical records (Brönnimann et al., 2019). For this reason temperature sensitive proxies such as tree and coral growth rings, ice-cores and lake sediments are used to reconstruct earlier climate variations (e.g.,
