ABSTRACT
People understanding of human environmental perception and response to change are also heavily dependent on the recent ethno historical record, a methodological key which used to unlock the mysteries of the past. Increasing concern over the potentially adverse effects of anthropogenic activity on global climate led to the establishment in 1988 of the Intergovernmental Panel on Climate Change (IPCC) under the aegis of the World Meteorological Organisation and the United Nations Environment Programme. The aims of the IPCC were, to assess available scientific information on climate change, to assess the environmental and socio-economic impacts of climate change, and to formulate response strategies. Although evidence for the ecological impacts of recent climate change found in both terrestrial and marine environments on current evidence it is difficult to predict the impact of future climate change on the world's forests, with modelling results suggesting subtle and often non-linear responses of forest ecosystems to global warming.
