Abstract: Micro-climate assessment in settlements; an environmenta-based approach built environment structuring. Global warming has become an emerging issue in the environmental field study. The urban conditions with all their environment development and layout still consider as majorrootcause for global warming. This literature study aimsed to find explanation for The rapid development of housing and high-rise buildings considered as a factor that responsible for an alternative approach in the effort of built environment restructuring. The results showed that the increasing of 70% global temperature within 1970 untills 2004. Moreover, the density of settlement area also believed as an affecting factor for air temperature increasement. In other words, the rapid presence of built environment contributes significantly to micro-climatic conditions. To accommodate the residential rapid development then the micro-climate assessment can be use as an alternative approach in the effort of built environment restructuring which can lead environmental quality improvement especially in settlement areas and to encourage the community involvement in the effort of sustainable development implementation. Keywords: micro-climate, micro-climatic characteristics, built environment, settelements

Global Carbon

Abstract In order to limit global warming, remaining carbon budgets have been defined by the IPCC in 2018. In this context translating global goals to local realities implicates a set of different challenges. Standardized methodologies of allocation can support a target-cascading process. On the other hand, local strategies and norms are not currently designed to directly respond to limited carbon budgets in a 2050 horizon. The life cycle assessment of buildings implicates an intricate cross-industry and cross-border carbon accounting. For these reasons, effective and aligned carbon targets are needed to support and guide all actors in the construction sector. This research aims at addressing these challenges by developing a new methodology of allocation of a global carbon budget at different scales using the Swiss built environment as a case study. This approach allows the assessment of current best practices in regards to limited carbon budgets. Results show misalignment of global goals with current practices at all levels and present the magnitude of effort that would be required to have a chance to limit global warming to 1.5°C.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
