Sam White the Real Little Ice Age Between C.1300 and C.1850 A.D
Journal of Interdisciplinary History, xliv:3 (Winter, 2014), 327–352. THE REAL LITTLE ICE AGE Sam White The Real Little Ice Age Between c.1300 and c.1850 a.d. the world became, on average, slightly but signiªcantly colder. The change varied over time and space, and its causes remain un- certain. Nevertheless, this cooling constitutes a meaningful climate event, with signiªcant historical consequences. Both the cooling trend and its effects on humans appear to have been particularly Downloaded from http://direct.mit.edu/jinh/article-pdf/44/3/327/1706251/jinh_a_00574.pdf by guest on 28 September 2021 acute from the late sixteenth to the late seventeenth century in much of the Northern Hemisphere. This article explains why climatologists and historians are conªdent that these changes occurred. On close examination, the objections raised in this issue of the journal by Kelly and Ó Gráda turn out to be entirely unfounded. The proxy data for early mod- ern global cooling (such as tree rings and ice cores) are robust, and written weather descriptions and observations of physical phenom- ena (such as glacial movements and river freezings) by and large of- fer independent conªrmation. Kelly and Ó Gráda’s proposed alter- native measures of climate and climate change suffer from serious ºaws. As we review the evidence and refute their criticisms, it will become clear just how solid the case for the Little Ice Age (lia) has become. the case for the little ice age The evidence for early modern global cooling comes, ªrst and foremost, from extensive research into physical proxies, including ice cores, tree rings, corals, and speleothems (stalagmites and stalactites). -

JON SHANKLIN Edited transcript of a recording of Jon Shanklin interviewed by Chris Eldon Lee on the 29th November 2013. BAS Archives AD6/24/1/236. Transcribed by Andy Smith, 5 March 2017. Part One [Part 1 0:00:00] Lee: This is Jon Shanklin, interviewed by Chris Eldon Lee, on the 29 th of November 2013. Jon Shanklin, Part 1. Shanklin: Jonathan Shanklin, born 1953, September the 29 th , in Wrexham, Denbighshire. [Part 1 0:00:18] Lee: Oh right? North Wales? Shanklin: North Wales. [Part 1 0:00:20] Lee: I live in Shrewsbury, so I know. Shanklin: I was in Shrewsbury in September actually. [Part 1 0:00:24] Lee: What, professionally? Shanklin: Amateurly because I am also a botanist. In fact I have just been appointed the Co-recorder for Cambridgeshire and there was a Recorders’ conference in the Gateway. [Part 1 0:00:39] Lee: Would you say your father was an educated man? Shanklin: Yes. [Part 1 0:00:42] Lee: Tell me about him. Shanklin: Dad was a consultant geologist at McAlpines, the big construction company, and so he would go off prospecting all over the place. I remember when I was a child he had several visits to South Africa, when he was away for months at a time. Probably rather like me, going to the Antarctic for months at a time, repaying the compliment, if you like. My mum was also a geologist, but mostly a mother, but they were both members of the local geological society. Dad at one time was a president of it, and they had regular excursions, and as children myself and my brother would be packed into the bus which would go down lanes that were very very narrow. -

It first appeared in a report on recent glacier advances in North America, 1 then in the title of an essay on the geological interpretation of glacier moraines in the Yosemite valley. Matthes was interested in the coolings since the postglacial climatic optimum, that is, over the last three thousand years, and especially in that which followed the medieval warm period. In his view, most glaciers still existing in North America do not go back to the last great ice age but have arisen in this relatively short space of time. The period from the thirteenth to the nineteenth century, in which glaciers advanced in the Alps, Scandinavia and North America, he called 'the Little Ice Age' (to distinguish it from the great ice ages). -
The Risk of Sea Level Rise
THE RISK OF SEA LEVEL RISE:∗ A Delphic Monte Carlo Analysis in which Twenty Researchers Specify Subjective Probability Distributions for Model Coefficients within their Respective Areas of Expertise James G. Titus∗∗ U.S. Environmental Protection Agency Vijay Narayanan Technical Resources International Abstract. The United Nations Framework Convention on Climate Change requires nations to implement measures for adapting to rising sea level and other effects of changing climate. To decide upon an appropriate response, coastal planners and engineers must weigh the cost of these measures against the likely cost of failing to prepare, which depends on the probability of the sea rising a particular amount. This study estimates such a probability distribution, using models employed by previous assessments, as well as the subjective assessments of twenty climate and glaciology reviewers about the values of particular model coefficients. The reviewer assumptions imply a 50 percent chance that the average global temperature will rise 2°C degrees, as well as a 5 percent chance that temperatures will rise 4.7°C by 2100. The resulting impact of climate change on sea level has a 50 percent chance of exceeding 34 cm and a 1% chance of exceeding one meter by the year 2100, as well as a 3 percent chance of a 2 meter rise and a 1 percent chance of a 4 meter rise by the year 2200. The models and assumptions employed by this study suggest that greenhouse gases have contributed 0.5 mm/yr to sea level over the last century. Tidal gauges suggest that sea level is rising about 1.8 mm/yr worldwide, and 2.5-3.0 mm/yr along most of the U.S. -
07 the Ozone Hole Jan14 V2.Indd
The Ozone Hole SCIENCE BRIEFING It’s nearly 30 years since the discovery of the Ozone Hole drew world attention to the impact of human activity on the global environment. Why is the ozone layer important? Is there a hole over the Arctic? The ozone layer is the Earth’s natural sunscreen that protects humans, plants Unlike Antarctica, which is a continent surrounded by oceans, the Arctic and animals by filtering out harmful UV-B radiation. In the 1970s concern is an ocean surrounded by mountainous continents. This means that the about the effect of man-made chemicals, especially chlorofluorocarbons stratospheric circulation is much more irregular. Because the Arctic ozone (CFCs), on the ozone layer were raised by Paul Crutzen, Mario Molina and layer is not normally as cold as that of the Antarctic, stratospheric clouds Sherwood Rowland. Their pioneering work was recognised in 1995 by the are less common. So although a deep ozone hole over the North Pole award of the Nobel Prize in Chemistry. is unlikely, ozone depletion can occur above the Arctic. When it does occur it usually lasts for a short period of time, however significant ozone How was the Ozone Hole discovered? depletion did occur in March 2011. Scientists from British Antarctic Survey (BAS) began monitoring ozone during the International Geophysical Year of 1957-58.
