[7] The cold summers can be maintained by sea-ice/ocean feedbacks long after volcanic aerosols are removed. This was associated with a 1.5 °C fall in temperature (determined from oxygen-isotope analysis) and an observed increase in El Niño frequency. the notion of the Little Ice Age as a globally synchronous cold period has all but been dismissed (Bradley and Jones, 1993; Mann et al., 1999). [72] The authors note "other unexplained climatic events comparable in duration and amplitude to the LIA and MWP events also appear. Sea ice surrounding Iceland extended for miles in every direction, closing harbors to shipping. Another possibility is that there was a slowing of thermohaline circulation. At first glance, that might not seem like much. 140 The Holocene13(2003) period in these 1500-yr cycles may have been the ‘ Little Ice Age’ (Lockwood, 2001). Ironically during this cold period Kilkenny experienced a dramatic population spurt. Some of the most popular theories include orbital cycles, solar activity, volcanic activity, human depopulation and ocean circulation. Date: February 12, 2021. Although there is some disagreement about exactly when the Little Ice Age started, records suggest that temperatures began cooling around 1250 A.D. There are substantial shorter term fluctuations in temperature, and since about 1850 world temperatures have been recovering from a Little Ice Age up by about +0.7°C up until the year 2000. [29] Native Americans formed leagues in response to food shortages. Evidence from several studies indicate that increases in violent actions against marginalized groups that were held responsible for the Little Ice Age overlap with years of particularly cold, dry weather. We tend to think in terms of day-to-day weather and there is not much difference between 0 and 2 C (32 and 35 F). [90][91] During the period 1645–1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum. The coldest conditions of the last 560 years were between AD 1570 and 1730, and in the nineteenth century. [112] The depopulation is linked to a drop in carbon dioxide levels observed at Law Dome, Antarctica. The Little Ice Age spanned a period from 1300 AD to 1850 AD, but the exact timing varies. He proposed, "Evidence has been accumulating in many fields of investigation pointing to a notably warm climate in … Our editors will review what you’ve submitted and determine whether to revise the article. [34] According to the science historian James Burke, the period inspired such novelties in everyday life as the widespread use of buttons and button-holes, and knitting of custom-made undergarments to better cover and insulate the body. 1660), and Laki (1783). [60], An analysis of several climate proxies undertaken in Mexico's Yucatán Peninsula, linked by its authors to Maya and Aztec chronicles relating periods of cold and drought, supports the existence of the Little Ice Age in the region. Sign in to download full-size image Figure 3. [62] The most recent of these cooling events was the Little Ice Age. These include large temperature excursions during the Little Ice Age (∼1400–1900 AD) and the Medieval Warm Period (∼800–1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation (THC). [36] Based on dating of a yellow-green lichen of the Rhizocarpon subgenus, the Mueller Glacier, on the eastern flank of the Southern Alps within Aoraki / Mount Cook National Park, is considered to have been at its maximum extent between 1725 and 1730. Five prominent cold periods are identified on a decadal timescale, centred on 1480, 1580, 1635, 1709 and 1784 and ‘Little Ice Age’ cooling spanning from 1450 to the early 18th century. Several causes have been proposed: cyclical lows in solar radiation, heightened volcanic activity, changes in the ocean circulation, variations in Earth's orbit and axial tilt (orbital forcing), inherent variability in global climate, and decreases in the human population (for example from the Black Death and the epidemics emerging in the Americas upon European contact[12]). ", The Siple Dome (SD) had a climate event with an onset time that is coincident with that of the Little Ice Age in the North Atlantic based on a correlation with the GISP2 record. [84] A 2009 paper details cooler and wetter conditions in southeastern South America between 1550 and 1800, citing evidence obtained via several proxies and models. 21. [115][116] The severe winters of 1770 to 1772 in Europe, however, have been attributed to an anomaly in the North Atlantic oscillation. But not every year was outsandingly cold during the Little Ice Age - but there were many cold years e.g. [79], Sea-level data for the Pacific Islands suggest that sea level in the region fell, possibly in two stages, between 1270 and 1475. [28], In his 1995 book the early climatologist Hubert Lamb said that in many years, "snowfall was much heavier than recorded before or since, and the snow lay on the ground for many months longer than it does today. [40] As a response to such violent scapegoating, Jewish communities sometimes converted to Christianity or migrated to the Ottoman Empire, Italy, or to territories of the Holy Roman Empire. [94] When a volcano erupts, its ash reaches high into the atmosphere and can spread to cover the whole earth. [50], Paintings and contemporary records in Scotland demonstrate that curling and ice skating were popular outdoor winter sports, with curling dating back to the 16th century and becoming widely popular in the mid-19th century. The colder climate is proposed to have caused the wood used in his violins to be denser than in warmer periods, contributing to the tone of his instruments. 1580), Huaynaputina (1600), Mount Parker (1641), Long Island (Papua New Guinea) (ca. During this coldest phase of the Little Ice Age there are indications that average winter temperatures in Europe and North America were as much as 2°C lower than at present. It seems unlikely that the human-caused Dust Bowl was the only Dust Bowl ever made by humans. [64], In Southern Africa, sediment cores retrieved from Lake Malawi show colder conditions between 1570 and 1820, suggesting the Lake Malawi records "further support, and extend, the global expanse of the Little Ice Age. [40] Europeans sought explanations for the famine, disease, and social unrest that they were experiencing, and blamed the innocent. [107][108] Richard Nevle, Robert Dull and colleagues further suggested that not only anthropogenic forest clearance played a role in reducing the amount of carbon sequestered in Neotropical forests, but that human-set fires played a central role in reducing biomass in Amazonian and Central American forests before the arrival of Europeans and the concomitant spread of diseases during the Columbian exchange. The cause of the Little Ice Age is not known for certain; however, climatologists contend that reduced solar output, changes in atmospheric circulation, and explosive volcanism may have played roles in bringing about and extending the phenomenon. The result is a picture of relatively cool conditions in the seventeenth and early nineteenth centuries and warmth in the eleventh and early fifteenth centuries, but the warmest conditions are apparent in the twentieth century. [32] According to Elizabeth Ewan and Janay Nugent, "Famines in France 1693–94, Norway 1695–96 and Sweden 1696–97 claimed roughly 10 percent of the population of each country. Dagamar Degroot, 'Did the Spanish Empire Change Earth's Climate?' Soon, it escalated to a huge conflict involving all major European powers that devastated much of Germany. [35], The Little Ice Age, by anthropologist Brian Fagan of the University of California at Santa Barbara, tells of the plight of European peasants during the 1300 to 1850 chill: famines, hypothermia, bread riots and the rise of despotic leaders brutalizing an increasingly dispirited peasantry. In the late 17th century, agriculture had dropped off dramatically: "Alpine villagers lived on bread made from ground nutshells mixed with barley and oat flour." Also emitted by eruptions is sulfur, in the form of sulfur dioxide gas. ", https://www.nps.gov/glba/learn/historyculture/people.htm, "Medieval Warm Period, Little Ice Age and 20th century temperature variability from Chesapeake Bay", "Abrupt Climate Changes Revisited: How Serious and How Likely? [47], Neuberger analysed 12,000 paintings, held in American and European museums and dated between 1400 and 1967, for cloudiness and darkness. Hans Steffen visited the area in 1898, noticing that the glacier penetrated far into the lagoon. [57][88][96][97] The circulation could have been interrupted by the introduction of a large amount of fresh water into the North Atlantic, possibly caused by a period of warming before the Little Ice Age known as the Medieval Warm Period. The coldest time was during the 16th and 17th Centuries. If defined as a large-scale event, the Little Ice Age must instead be considered a time of mod-est cooling of the Northern Hemisphere, with temperatures dropping by about 0.6°C during the 15th–19th centuries Some scientists therefore argue that reduced amounts of available solar radiation caused the Little Ice Age. Both solar minimums coincided with the coldest years of the Little Ice Age in parts of Europe. [105][106] Other researchers supported depopulation in the Americas as a factor, asserting that humans had cleared considerable amounts of forest to support agriculture in the Americas before the arrival of Europeans brought on a population collapse. [47] Wintry scenes, which entail technical difficulties in painting, have been regularly and well handled since the early 15th century by artists in illuminated manuscript cycles showing the Labours of the Months, typically placed on the calendar pages of books of hours. His son Pieter Brueghel the Younger (1564–1638) also painted many snowy landscapes, but according to Burroughs, he "slavishly copied his father's designs. [41] Oppressed groups, however, took the brunt of the burden in attempts to cure it. Not everybody agreed that witches should be persecuted for weather-making, but such arguments primarily focused not upon whether witches existed, but upon whether witches had the capability to control the weather. [53] It started as a war of succession to the Bohemian throne. This was particularly evident during the 'Grindelwald Fluctuation' (1560-1630): a rapid cooling phase that was associated with more erratic weather - including increased storminess, unseasonal snow storms and droughts. Before discussing the Little Ice Age we should be clear what a proper ice age is. [110] Brierley conjectured that European arrival in the Americas caused mass deaths from epidemic disease, which caused much abandonment of farmland, which caused much return of forest, which sequestered greater levels of carbon dioxide. However, these regional temperature declines rarely occurred at the same time. The most prominent feature of the record is a period of elevated summer temperatures from 1200-1375 AD, followed by cooler conditions from 1375-1820 AD, coincident with the Little Ice Age. [109][110][111] Dull and Nevle calculated that reforestation in the tropical biomes of the Americas alone from 1500 to 1650 accounted for net carbon sequestration of 2-5 Pg. Research has also shown that global average surface temperatures only cooled by about 0.5 degrees Celsius during the Little Ice Age. Little Ice Age (LIA), climate interval that occurred from the early 14th century through the mid-19th century, when mountain glaciers expanded at several locations, including the European Alps, New Zealand, Alaska, and the southern Andes, and mean annual temperatures across the Northern Hemisphere declined by 0.6 °C (1.1 °F) relative to the average temperature between 1000 and 2000 ce. "[29] In Lisbon, Portugal, snowstorms were much more frequent than today; one winter in the 17th century produced eight snowstorms. The Little Ice Age is best known for its effects in Europe and the North Atlantic region. [27] The Norse colonies in Greenland starved and vanished by the early 15th century, as crops failed and livestock could not be maintained through increasingly harsh winters. The Intergovernmental Panel on Climate Change Third Assessment Report (TAR) of 2001 described the areas affected: Evidence from mountain glaciers does suggest increased glaciation in a number of widely spread regions outside Europe prior to the twentieth century, including Alaska, New Zealand and Patagonia. “Exploring the North in a Changing Climate: The Little Ice Age and the Journals of Henry Hudson, 1607-1611.” Journal of Northern Studies 9:1 (2015): 69-91. [67], In Ethiopia and North Africa, permanent snow was reported on mountain peaks at levels where it does not occur today. Lake records in Victoria suggest that conditions, at least in the south of the state, were wet and/or unusually cool. However, the absence of sunspots has not explained the brief cooling episodes that occurred in other parts of the world during this time. [44][45], William James Burroughs analyses the depiction of winter in paintings, as does Hans Neuberger. In Estonia and Finland in 1696–97, losses have been estimated at a fifth and a third of the national populations, respectively. ... Little Ice Age. [47][49], Burroughs says that snowy subjects return to Dutch Golden Age painting with works by Hendrick Avercamp from 1609 onwards. It was directly preceded by an unusually warm epoch, known as the Medieval Warm Period. [40][42] Christianity was the official religion of Western Europe, and within these populations there was a great degree of anti-Semitism. [43] Although these communities had some contingency plans, such as better crop mixes, emergency grain stocks, and international food trade, these did not always prove effective. [86], Although only anecdotal evidence, in 1675 the Spanish Antonio de Vea expedition entered San Rafael Lagoon through Río Témpanos (Spanish for "Ice Floe River") without mentioning any ice floe but stating that the San Rafael Glacier did not reach far into the lagoon. At the beginning of the Holocene - after the end of the last Ice Age - global temperature increased, and subsequently it decreased again by 0.7 ° C over the past 5000 years. [102] In total, the plague may have reduced the world population from an estimated 475 million to 350–375 million in the 14th century. The Little Ice Age was… little. The Little Ice Age events are characterized by a drop in temperature of 0.5–1°C in Greenland and a sea surface temperature falls of 4°C off the coast of west Africa and 2°C off the Bermuda Rise (see Figure 3). [41] Other regulations affected the wider population, such as prohibiting dancing and sexual activities, as well as moderating food and drink intake. Many areas of northern Europe, for instance, were subjected to several years of long winters and short, wet summers, whereas parts of southern Europe endured droughts and season-long periods of heavy rainfall. Today some scientists use it to distinguish only the period 1500–1850, when mountain glaciers expanded to their greatest extent, but the phrase is more commonly applied to the broader period 1300–1850. DISCU SSION The Earth has been ice-free (even at the poles) for most of its history. Cooler episodes also materialized in the Southern Hemisphere, initiating the advance of glaciers in Patagonia and New Zealand, but these episodes did not coincide with those occurring in the Northern Hemisphere. Clastic varved sediments from Donard Lake, in the Cape Dyer region of Baffin Island, provide a 1250 yr record of decadal-to-centennial scale climate variab There is substantial historical evidence for the Little Ice Age.
