Climate Change has been acknowledged as one of the single greatest threats to global social, environmental and economic wellbeing. Climate change poses significant threats to existing urban infrastructure, current water use practices and agricultural industries to name a few. In the State of Victoria in Australia, there is an e-Science initiative to mobilise cross-organisational expertise in or...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
The Community Atmosphere Model (CAM), which serves as the atmosphere component of the Community Climate System Model (CCSM), is currently the most computationally expensive CCSM component in typical configurations. Improving performance scalability in CAM has been a challenge, due largely to algorithmic restrictions necessitated by the polar singularities in its latitude-longitude computational...
The United Nations, Food and Agricultural Organization [FAO, Steinfeld, Gerber, Wassenaar, Castel, Rosales, and de Haan (2006). Livestock’s Long Shadow. Food and Agriculture Organization of the United Nations] report titled Livestock’s Long Shadow (LLS) stated that 18% (approximately 7100 Tg CO2eq yr ) of anthropogenic greenhouse gases (GHGs) are directly and indirectly related to the world’s l...
century exceeds natural variability, and thus some of it may be due to anthropogenic carbon dioxide (Stevens, “Experts confirm human role in global warming,” New York Times, Sept. 10, 1995, page 1). This weak claim, unfortunately, is based on the assumption that variability in models is the same as variability in nature. This is not widely believed. Although the scientific statement of this pro...
The Intergovernmental Panel on Climate Change’s (IPCC) ‘‘very likely’’ statement that anthropogenic emissions are affecting climate is based on a statistical detection and attribution methodology that strongly depends on the characterization of internal climate variability. In this paper, the authors test the robustness of this statement in the case of global mean surface air temperature, under...
Climate change is an important social issue and the subject of much research, both to understand the history of the Earth’s changing climate and to foresee what changes to expect in the future. Approximately every five years starting in 1990 the Intergovernmental Panel on Climate Change (IPCC) publishes a set of reports that cover the current state of climate change research, how this research ...
