Central England Temperature

An analysis of Little Ice Age temperatures, using the Central England Temperature dataset (HadCET) shows that all temperature decreases were due to dimming sulfurous emissions from volcanic eruptions. There was no cooling effect, at any time, from the absence of sunspots.

From the years 1300 until the 1850’s people living in Western Europe battled a terrifying and seemingly insurmountable foe, the Little Ice Age. Examining how people of this time not only survived but thrived during an era of cataclysmic climate change can offer us positive perspectives and productive mechanisms going forward in our own battle with climate in modern times. Explored are massive famines and epidemic disease, volcanic eruptions and their after-effects, specific historical events such as the Black Plague and the Irish Potato famine and how all of these devastating events overlap to create a vivid picture of human fortitude. This article uncovers the tools and ingenuity Western Europeans employed to overcome a rapidly changing climate and how those tools are properly utilized to battle devastating climatic events. In exploring both scientific theory, including   anthropological works such as Anthony Wallace’s Revitalization Movement, and the modern church’s position on climate change, this article hopes to address the current circumstance of global climate change and provide a potential way forward for modern humans in light of scientific reason and theological discussion about our unavoidable role in the environment.

Analysis of the Central England Temperatures data set has provided the answer to the cause of the decreased temperatures during the Little Ice Age (LIA) (and undoubtedly, all of the others). They were caused by the Sulfur Dioxide (SO2) aerosol emissions from an extensive occurrence of VEI4-VEI7 volcanic eruptions.

Paleoclimate reconstructions for the western US show spatial variability in the timing, duration, and magnitude of climate changes within the Medieval Climate Anomaly (MCA, ca. 900–1350 CE) and Little Ice Age (LIA, ca. 1350–1850 CE), indicating that additional data are needed to more completely characterize late-Holocene climate change in the region. Here, we use dendrochronology to investigate how climate changes during the MCA and LIA affected a treeline, whitebark pine ( Pinus albicaulis Engelm.) ecosystem in the Greater Yellowstone Ecoregion (GYE). We present two new millennial-length tree-ring chronologies and multiple lines of tree-ring evidence from living and remnant whitebark pine and Engelmann spruce ( Picea engelmannii Parry ex. Engelm.) trees, including patterns of establishment and mortality; changes in tree growth; frost rings; and blue-intensity-based, reconstructed summer temperatures, to highlight the terminus of the LIA as one of the coldest periods of the last millennium for the GYE. Patterns of tree establishment and mortality indicate conditions favorable to recruitment during the latter half of the MCA and climate-induced mortality of trees during the middle-to-late LIA. These patterns correspond with decreased growth, frost damage, and reconstructed cooler temperature anomalies for the 1800–1850 CE period. Results provide important insight into how past climate change affected important GYE ecosystems and highlight the value of using multiple lines of proxy evidence, along with climate reconstructions of high spatial resolution, to better describe spatial and temporal variability in MCA and LIA climate and the ecological influence of climate change.

The Relationship

The Late Antique Little Ice Age, spanning the period from 536 CE to roughly 560 CE, saw temperatures in the Northern Hemisphere drop by a degree C in less than a decade. This rapid cooling is thought to have caused widespread famine, epidemic disease, and social disruption. The relationship between cooling and social disruption is examined here using a set of high-resolution climate and historical data. A significant link between cooling and social disruption is demonstrated, but it is also demonstrated that the link is highly variable, with some societies experiencing dramatic cooling changing very little, and others experiencing only slight cooling changing dramatically. This points to variation in vulnerability, and serves to establish the Late Antique Little Ice Age as a context within which naturalistic quasi-experiments on vulnerability to climate change might be conducted.

Time series depicting mountain glacier fluctuations in the Alps display generally similar patterns over the last two centuries, as do chronologies of glacier variations for the same interval from elsewhere in the Northern Hemisphere. Episodes of glacier advance consistently are associated with intervals of high average volcanic aerosol production, as inferred from acidity variations in a Greenland ice core. Advances occur whenever acidity levels rise sharply from background values to reach concentrations ≥1.2 μequiv H+/kg above background. A phase lag of about 10–15 yr, equivalent to reported response lags of Alpine glacier termini, separates the beginning of acidity increases from the beginning of subsequent ice advances. A similar relationship, but based on limited and less-reliable historical data and on lichenometric ages, is found for the preceding 2 centuries. Calibrated radiocarbon dates related to advances of non-calving and non-surging glaciers during the earlier part of the Little Ice Age display a comparable consistent pattern. An interval of reduced acidity values between about 1090 and 1230 A.D. correlates with a time of inferred glacier contraction during the Medieval Optimum. The observed close relation between Noothern Hemisphere glacier fluctuations and variations in Greenland ice-core acidity suggests that sulfur-rich aerosols generated by volcanic eruptions are a primary forcing mechanism of glacier fluctuations, and therefore of climate, on a decadal scale. The amount of surface cooling attributable to individual large eruptions or to episodes of eruptions is simlar to the probable average temperature reduction during culminations of Little Ice Age alacier advances (ca. 0.5°–1.2°C), as inferred from depression of equilibrium-line altitudes.
