Pre-industrial to 2000 ppm; soybean response to increasing CO2
… security in the next century. The majority of previous studies have focused on scenarios published in the Intergovernmental Panel on Climate Change (IPCC) reports. None of these scenarios have accurately predicted the rise in recent years of [CO2]; in fact, measured [CO2] has exceeded the …

Changes in Diatom Assemblages in Adirondack (NY, USA) Reference Lakes Since Pre-Industrial Times
… of Adirondack lakes have been impacted since pre-industrial time through either regional (e.g. acidification) or local (e.g. fish stocking, liming, seepage of road salt, cultural eutrophication) environmental disturbances. Inferring changes related to climate are difficult due to the possible …

Ice core methane and carbon monoxide as tracers of the terrestrial biosphere since the pre-industrial
… the 19th and 20th centuries—superimposed on industrially driven increases in their concentration— have therefore remained challenging. In this thesis, multiple high snow accumulation Antarctic ice cores are utilised to continuously reconstruct the mixing ratios of atmospheric methane (CH4) …

Pre-industrial trade on the River Severn: a computer-aided study of the Gloucester port books, c1640-c1770
… thesis addresses aspects of internal trade in pre-industrial England and Wales in order to shed new light on its volume, patterns, contents, conduct and development, and to develop new methods for its study. It focuses on the evaluation, computerisation, and analysis of coastal Port Books for …

Evaluating temperature and precipitation extremes under 1.5°C and 2.0°C warming above pre-industrial levels: Botswana case study
… of further warming to 1.5 and 2.0 °C above preindustrial levels. Climate extremes are expected to become more severe as the global climate continues to warm due to anthropogenic greenhouse gas emissions. The extent to which extremes and their impacts are to change due to additional 0.5 °C …

Seven peasant communities in pre-industrial Europe. A comparative study of French, Italian and Swedish rural parishes (18th and early 19th century)
… social structure of seven peasant communities in pre-industrial Europe: four French, one Italian and two Swedish. It is concerned with elements of the social structure such as family and kinship organization, geographical mobility and the life cycle of individuals.' It also describes the relations …

Religious belief and social control, with special reference to patterns of stability and change in classical Athens and ancient Egypt
… the problem of order in the context of complex pre-industrial society which, whilst not completely., static, exhibits more clearly and comprehensively the persistent features of institutional life. The discussion rests upon a typification of Static and Dynamic societies. The Static society is …

The Influence of Anthropogenic Climate Change on the 2015-2017 Hydrological Drought in the South-Western Cape, South Africa
… drought event since 1904 and caused severe unprecedented water shortages throughout the Western Cape region, with many municipal water supply systems close to failure by the first quarter of 2018; most especially the Western Cape Water Supply System that serves Cape Town. The drought gained a …

Improving the understanding of the influence of emissions of biogenic volatile organic compounds on climate.
… standard and state-of-the-art mechanisms in a pre-industrial atmosphere with a focus on the gas and aerosol phase changes. Updates to chemistry in the state-of-the-art mechanism result in greater terrestrial boundary layer OH and improved model performance against observations compared to …

Rural sports in Wales, c.1750-c.1900: continuity and change
… underutilised material, it will be shown how in preindustrial society especially, sport fulfilled a vital function among the common people, whose lives were otherwise dominated by arduous daily labour. Conversely, the gentry enjoyed ample free time, much of which was spent practising exclusive …

Scrimshaw: unlocking the cultural and biological archive of sea mammal art
… century the folk-art tradition ‘scrimshaw’, predominantly using the teeth of sperm whales (Physeter macrocephalus), flourished among the crews of industrial whaling ships. Scrimshaw collections represent a unique cultural and biological archive of pre-industrial/industrial sperm whale …

Fundamental aerosol-cloud interactions and their influence on the aerosol indirect effect on climate
… greatly reduce the mean error in droplet number predicted across regimes. The biases in these parameterizations raise questions the influence of activation on the indirect effect. Using different schemes, we calculate a spread of 1 W m- 2 in the indirect effect, which we show is equal to the …

Exploring mechanisms for the decrease of atmospheric CO₂ during the last glacial maximum using a four-box ocean model
… revealed that atmospheric CO2 decreased from a pre-industrial concentration of 280 ppmV to approximately 200 ppmV during the last glacial maximum (Petit et al., 1999). Several hypotheses as to why this happened have been suggested yet no one explanation has been able to fully account for this …

Detailed paleoclimatic records from late Pennsylvanian polygenetic paleosols : north-central Texas, USA.
… pedogenic calcite nodules indicate values near pre-industrial levels (360ppmV), which are in agreement with previously published proxy and modeling results. This study shows that despite multiple episodes of overprinting, a detailed paleoclimatic and paleohydrologic history can be reconstructed …
