Скачать книгу - Tropics of Savagery

The global climate changes that led to the expansion and contraction of high latitude ice sheets during the Quaternary period were associated with equally dramatic changes in tropical environments. These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have acted as drivers of global climate change over a range of timescales. The aim of Quaternary Environmental Change in the Tropics is to provide a synthesis of the changes that occurred in tropical terrestrial and marine systems during the Pleistocene and Holocene, complementing data-derived reconstructions with output from state-of-the-art climate models. It is targeted at final-year undergraduate students and research specialists, but will provide an introduction to tropical Quaternary research for a variety of other readers.

What do we mean by the tropics? The weather and the climates it produces across the tropical zone are significantly different from those experienced by the people living in higher latitudes, so forecasters across Europe and much of North America are unfamiliar with its effects. In this book, Jim Galvin demystifies the topic in this zone that is increasingly of interest to those studying weather and climate. This book was written for weather forecasters, meteorology, environmental science and geography students as an introductory guide. It builds on the experience of the author, his professional experience in the World Area Forecast Centre at the Met Office, Exeter, using studies into the weather and climate seen within the tropical air mass conducted over many years. Its unique approach presents a practical approach to tropical weather studies, drawing on both academic and practical knowledge, covering air mass dynamics, seasonal changes, moist and dry weather, climate variability and human health in chapters and appendices that build up the overall picture, summarising our current state of knowledge. As an overview, it covers the broad range of effects connected with climate and weather in a straightforward way and is clearly illustrated throughout.

One man’s journey in the footsteps of a great explorer into the heart of Africa.As a young man, Warwick Cairns met the then elderly explorer Wilfred Thesiger and the two men struck up an unlikely friendship. Invited to visit him at his African home, Cairns decides to make a bit of an adventure of it and do some of the journey on foot.When he himself was a young man, Thesiger led an expedition to explore the course of the Awash river in Ethiopia. Every westerner that had gone before him had been killed by local tribesmen. Needless to say, he survived.Alternating chapters chart Warwick’s journey with that of Thesiger creating a captivating dual narrative that is part travel book, part biography, part autobiography, part history with fair doses of philosophy and humour thrown in for good measure.In Praise of Savagery is a highly original book that defies classification but is always effortlessly readable.
