Een meeslepende ontdekkingstocht langs de boomgrens waarin de effecten van klimaatverandering voelbaar worden. ‘Naast bomen en bossen zijn bijzondere mensen de hoofdpersonen in De boomgrens. Juist die combinatie maakt het lezen van dit boek heel aantrekkelijk.’ – NRC (5 sterren) De afgelopen 50 jaar krimpen de noordelijke sneeuwbossen in een rap tempo. Hier worden de geologische effecten van klimaatverandering voor het eerst pijnlijk zichtbaar. Ben Rawlence neemt ons mee langs die cruciale grenslijn – van Noorwegen naar Siberië, van Alaska tot Groenland – en combineert een reisverhaal met journalistiek en wetenschap. Hij portretteert 6 boomsoorten, hun mysterieuze werking op de lucht waar wij afhankelijk van zijn, en schetst een verontrustend toekomstbeeld. Volgens het NRC was De boomgrens een van de beste boeken van het afgelopen jaar.
Magnetism is important in environmental studies for several reasons, the two most fundamental being that most substances exhibit some form of magnetic behavior, and that iron is one of the most common elements in the Earth's crust. Once sequestered in a suitable material, magnetic particles constitute a natural archive of conditions existing in former times. Magnetism provides a tracer of paleo-climatic and paleo-environmental conditions and processes.Environmental Magnetism details the occurrence and uses of magnetic materials in the natural environment. The first half of the volume describes the basic principles. The second half discusses the applications of magnetic measurements in various environmental settings on land, in lakes, in the ocean, and even various biological organisms.* Material is broadly applicable to environmental studies* Case histories illustrate key points* Extensive bibliography makes further research quick and easy
The morphology of Earth's surface reflects the interaction of climate, tectonics and denudational processes operating over a wide range of spatial and temporal scales. These processes can be considered catastrophic or continuous; depending on the timescale of observation or interest. Recent research had required integration of historically distinct subjects such as geomorphology, sedimentology, climatology and tectonics. Together, these have provided new insights into absolute and relative rates of denudation, and the factors that control the many dynamic processes involved. Specific subject areas covered are sediment transport processes and the timescales of competing processes, the role of the geological record and landscapes in constraining different processes, the nature of landscape evolution at different spatial scales and in contrasting geological environments.

This book provides a cross-disciplinary overview of permafrost and the carbon cycle by providing an introduction into the geographical distribution of permafrost, with a focus on the distribution of permafrost and its soil carbon reservoirs. The chapters explain the basic physical properties and processes of permafrost soils: ice, mineral and organic components, and how these interact with climate, vegetation and geomorphological processes. In particular, the book covers the role of the large quantities of ice in many permafrost soils which are crucial to understanding carbon cycle processes. An explanation is given on how permafrost becomes loaded with ice and carbon. Gas hydrates are also ...
