Washington DC: AAAS, 2009. 1st Edition. FIRST EDITION IN ORIGINAL WRAPS of a paper by Mann showing that the global pattern of warming that characterized the Medieval Climate Anomaly was a dynamical response to solar forcing. He goes on to show that temperature changes in the little ice age involve el Nino and the North Atlantic Oscillation-Arctic Oscillation, implying important regional effects of warming such as drought.
“The global climate record of the past 1500 years shows two long intervals of anomalous temperatures before the obvious anthropogenic warming of the 20th century: the warm Medieval Climate Anomaly between roughly 950 and 1250 A.D. and the Little Ice Age between around 1400 and 1700 A.D. It has become increasingly clear in recent years, however, that climate changes inevitably involve a complex pattern of regional changes, whose inhomogeneities contain valuable insights into the mechanisms that cause them.
“Mann et al. analyzed proxy records of climate since 500 A.D. and compared their global patterns with model reconstructions. The results identify the large-scale processes—like El Niño and the North Atlantic Oscillation—that can account for the observations and suggest that dynamic responses to variable radiative forcing were their primary causes” (Hurtley, Patterns of Change, Science 2009).
