Impacts Of Climate Change

<p>Hydrological processes in mountainous catchments will be subject to climate change on all scales, and their response is expected to vary considerably in space. Typical hydrological studies, which use coarse climate data inputs obtained from General Circulation Models (GCM) and Regional Climate Models (RCM), focus mostly on statistics at the outlet of the catchments, overlooking the effects within the catchments. Furthermore, the role of uncertainty, especially originated from natural climate variability, is rarely analyzed. In this work, we quantified the impacts of climate change on hydrological components and determined the sources of uncertainties in the projections for two mostly natural Swiss alpine catchments: Kleine Emme and Thur. Using a two-dimensional weather generator, AWE-GEN-2d, and based on nine different GCM-RCM model chains, we generated high-resolution (2 km, 1 hour) ensembles of gridded climate inputs until the end of the 21<sup>st</sup> century. The simulated variables were subsequently used as inputs into the fully distributed hydrological model Topkapi-ETH to estimate the changes in hydrological statistics at 100-m and hourly resolutions. Increased temperatures (by 4°C, on average) and changes in precipitation (decrease over high elevations by up to 10%, and increase at the lower elevation by up to 15%) results in increased evapotranspiration rates in the order of 10%, up to a 50% snowmelt, and drier soil conditions. These changes translate into important shifts in streamflow seasonality at the outlet of the catchments, with a significant increase during the winter months (up to 40%) and a reduction during the summer (up to 30%). Analysis at the sub-catchment scale reveals elevation-dependent hydrological responses: mean annual streamflow, as well as high and low flow extremes, are projected to decrease in the uppermost sub-catchments and increase in the lower ones. Furthermore, we computed the uncertainty of the estimations and compared them to the magnitude of the change signal. Although the signal-to-noise-ratio of extreme streamflow for most sub-catchments is low (below 0.5) there is a clear elevation dependency. In every case, internal climate variability (as opposed to climate model uncertainty) explains most of the uncertainty, averaging 85% for maximum and minimum flows, and 60% for mean flows. The results highlight the importance of modelling the distributed impacts of climate change on mountainous catchments, and of taking into account the role of internal climate variability in hydrological projections.</p>

Impacts Of Climate Change

This chapter examines the scope of existing international law to address ‘climate change-related displacement’, a term used to describe movement where the impacts of climate change affect mobility decisions in some way. It looks into the role of international refugee law, human rights law, and the law on statelessness in protecting people displaced by the impacts of climate change. The extent to which international law and international institutions respond to climate change-related movement and displacement depends upon: whether such movement is perceived as voluntary or forced; the nature of the trigger; whether international borders are crossed; the extent to which there are political incentives to characterize movement as linked to climate change or not; and whether movement is driven or aggravated by human factors, such as discrimination. The chapter also considers the extent to which existing principles on internal displacement provide normative and practical guidance.

Impacts Of Climate Change

The book applies a justice framework to analysis of the actual and potential role of international law with respect to people on the move in the context of anthropogenic climate change. That people are affected by the impacts of climate change is no longer doubted, including with implications for the movement of people (migration, displacement, relocation, etc.). The book tackles unique questions concerning international responsibility for people movement arising from the inequities inherent to climate change. Corrective and distributive justice provide the analytical backbone. They are explored in a substantial theoretical chapter and then applied to subsequent contextual analysis. Corrective justice supports analysis as to whether people movement in the climate change context could be conceived or framed as harm, loss, or damage which is compensable under international law, either through fault-centred regimes or no-fault regimes (i.e., insurance). Distributive justice supports analysis as to whether such movement could be conceived or framed as a disproportionate burden, either for those faced with movement or those faced with sheltering people on the move, from which duties of redistribution may stem. The book contributes to the growing scholarship and analysis concerning international law or governance and people movement in response to climate change by investigating the bounds of the law where the phenomenon is viewed as one of (in)justice.

Impacts Of Climate Change

While there are many studies about the environmental impacts of climate change in the Canadian north, the role of Indigenous youth in climate governance has been a lesser focus of inquiry. A popularized assumption in some literature is that youth have little to contribute to discussions on climate change and other aspects of land and resource management; such downplay of youth expertise and engagement may be contributing to climate anxiety (e.g., feelings of hopelessness), particularly in remote communities. Creating opportunities for youth to have a voice in global forums such as the United Nations Conference of Parties (COP24) on Climate Change may offset such anxiety. Building on previous research related to climate action, and the well-being of Indigenous youth, this paper shares the outcomes of research with Indigenous youth (along with family and teachers) from the Mackenzie River Basin who attended COP24 to determine the value of their experience. Key questions guiding these interviews included: How did youth impact others? and How did youth benefit from the experience? Key insights related to the value of a global experience; multiple youth presentations at COP24 were heard by hundreds of people who sought to learn more from youth about their experience of climate change. Additional insights were gathered about the importance of family and community (i.e., webs of support); social networks were seen as key to the success of youth who participated in the event and contributed to youth learning and leadership development.
