Guy Stewart Callendar (1898–1964) is noted for identifying, in 1938, the link between the artifcial production of carbon dioxide and global warming. Today this is called the “Callendar Efect. ” He was one of Britain’s leading steam and combustion engineers, a specialist in infrared physics, author of the standard reference book on the properties of steam at high tempe- tures and pressures, and designer of the burners of the notable World War II airfeld fog dispersal system, FIDO. He was keenly interested in weather and climate, taking measurement so accurate that they were used to correct the ofcial temperature records of central England and collecting a series of worldwide weather data that showed an unprecedented warming trend in the frst four decades of the twentieth century. He formulated a coherent theory of infrared absorption and emission by trace gases, established the nineteenth-century background concentration of carbon dioxide, and - gued that its atmospheric concentration was rising due to human activities, which was causing the climate to warm. Callendar’s contributions to climatology led the way in the mid-twentie- century transition from the traditional practice of gathering descriptive c- mate statistics to the new and exciting feld of climate dynamics. In the frst half of the twentieth century, the carbon dioxide theory of climate change xiv Introduction had fallen out of favor with climatists.
First published in 1977, the second volume of Climate: Present, Past and Future covers parts 3 and 4 of Professor Hubert Lamb’s seminal and pioneering study of climatology. Part 3 provides a survey of evidence of types of climates over the last million years, and of methods of dating that evidence. Through the earlier stages of the Earth’s development the book traces what is known of the various geographies presented by the drifting continents and indicates what can be learnt about climatic regimes and the causes of climatic change. From the last ice age to the present our knowledge of the succession of climates is summarized, indicating prevailing temperatures, rainfalls, wind and ocean current patterns where possible. Part 4 considers events during the fifteen years prior to the book’s initial publication, leading on to the problems of estimating the most probable future course of climatic development, and the influence of Man’s activities on climate. Alongside the reissue of volume 1, this Routledge Revival will be essential reading for anyone interested in both the causes and workings of climate and in the history of climatology itself.
In response to a request from Congress, Surface Temperature Reconstructions for the Last 2,000 Years assesses the state of scientific efforts to reconstruct surface temperature records for Earth during approximately the last 2,000 years and the implications of these efforts for our understanding of global climate change. Because widespread, reliable temperature records are available only for the last 150 years, scientists estimate temperatures in the more distant past by analyzing "proxy evidence," which includes tree rings, corals, ocean and lake sediments, cave deposits, ice cores, boreholes, and glaciers. Starting in the late 1990s, scientists began using sophisticated methods to combine proxy evidence from many different locations in an effort to estimate surface temperature changes during the last few hundred to few thousand years. This book is an important resource in helping to understand the intricacies of global climate change.
