Causes of irregularities in trends of global mean surface temperature since the late 19th century. [PDF]
Sci Adv, 2018 Our analyses provide empirical explanations for slowdowns and irregularities in global surface temperature variation, 1891–2015. The time series of monthly global mean surface temperature (GST) since 1891 is successfully reconstructed from known natural ...
