Geographers have played an important and sometimes controversial role in the study of climate during the 20 th century. This review traces the historical contributions of geographical scholarship to the study of climate in two primary areas: statistical, descriptive climatology and research in climate and society. It draws out the specifically geographical nature of climatological work in the first part of the 20 th century, looking at the role of maps, classifications and historical statistics in describing and potentially explaining climatic cycles, patterns and processes. Geographers were keen to demonstrate the broader linkages between climate and the physical environment and humankind, such that applications of climatological expertise were crucial to economic development, imperialism and local scales, particularly the urban scale. This led geographers into insightful interdisciplinary applications, but also rather more awkward themes such as climatic determinism.The review draws out both the positive and negative aspects of geographer's contribution to understandings of climate.
IntroductionClimate has rarely been far from the core of geographical enquiry, yet studies of climate have had a sometimes controversial role within geography as a discipline. Frequently shamed for climatic determinism, the spectre of characters like Griffith Taylor and Ellsworth Huntington cast a shadow across geographical contributions to work on climate and society 1 . Even attempts at researching climate systems and processes have had a variegated history as geography has competed with other disciplines, particularly atmospheric physics, for credibility and value. Whether in constructing a classification of the world's climatological regions, using past climate cycles for weather prediction or attempting to explain society's (racial, economic, cultural) relationship with climate, geographers have nonetheless created insights and developed ways of thinking that are still relevant and inspire contemporary research on climate change.Despite the conviction of (some) geographers in their mission to place geographical knowledge at the heart of academic enterprise with claims such as that "Ever since the dimmest antiquity the spirit of man has felt the need for geographical i.e. earth-describing, knowledge" 2 (Reference 2, p1.); if we fast-forward to the 1960s and 1970s, such an ambition appeared to be in crisis. Geography textbooks became replete with disclaimers about the stale nature of a purely descriptive, regional climatology 3 . This was particularly unfortunate since, as the eminent geographer and climatologist Gordon Manley suggested, climatology had become the next big field of research after having for so long been "something we took for granted as a rather depressing part of school geography" 4 (Reference 4, p360). It is the purpose of this review paper to outline geography's contributions to understanding climate through the 20 th century, incorporating the disconcerting (climatic determinism) and the perceived ol...
