ous prospect, political negotiations have sought to establish an international regulatory policy to constrain greenhouse gas emissions. Major new treaties— the 1992 Framework Convention on Climate Change and the 1997 Kyoto Protocol—have been negotiated. But identifying the problem is not the same as crafting the solution. Climate science is a necessary but not sufficient basis for climate polic...

the effect of environmental factors on plant vegetation is different. therefore, it is necessary to evaluate role of these factors in medicinal plants growth, development and essential oil. this study was performed to investigate the effect of factors on qualitative and quantitative variations of the essential oil of verbascum songaricum in its habitats in central zagros mountains, iran in 2012...

In this paper we look at the motivations of managers of small and medium sized enterprises (SMEs) to engage with climate change. The paper reports on an exploratory, qualitative study with managers of nine environmentally proactive SMEs in the East of England. The aim of the research was to study what motivated managers of SMEs to engage with environmental issues in general and with climate cha...

climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...

Climate type is one of the potentially most relevant pieces of metadata for identifying studies in evidence-based environmental management. In this paper, we propose a method for automatically predicting the climate type in environmental science literature using NLP techniques, relative to a pre-existing set of climate type categories. Our main approaches combine toponym detection and resolutio...

Mann et al. (2005, hereafter M05) conclude that they “find no evidence for the suggestion that real-world proxy-based temperature reconstructions are likely to suffer from any systematic underestimate of lowfrequency variability.” This conclusion is based on multiple pseudoproxy experiments using the National Center for Atmospheric Research (NCAR) Climate System Model (CSM) millennial integrati...

abstract norton’s (1995) investment hypothesis in l2 learning that l2 learners who cherish and foresee a richer personality for themselves in their l2 context would thrive more diligently and consequently would both enrich their personality and achieve a higher proficiency in their new language was investigated in this study in the community of iranian efl students. the integration and mutual r...
