Copenhagen failure : a rhetorical treatise of how speeches unite and divide mankind

2010

The purpose of this treatise is to analyse five of the Copenhagen Climate Convention's main speeches to see how they supported or weakened the agreement possibilities in the convention. Particular focus will be on the elements that divide or unite negotiators and whether the summit's failing outcome is already built in the pre-planned speeches held at the main podium. Theoretically, the study builds on Kenneth Burke's identification thesis and Elizabeth L. Malone's climate change debate analysis. I combine these in my analysis using a revised version of Malone's argument family classification tool putting it into Burke's theoretical framework. The central concept is Burke's identification, …

This document summarizes the key aspects of the EU Commission's strategy to harness the potential of offshore renewable energy.

Anthropogenic Influences in Land Use/Land Cover Changes in Mediterranean Forest Landscapes in Sicily

2016

This paper analyzes and quantifies the land use/land cover changes of the main forest and semi-natural landscape types in Sicily between 1955 and 2012. We analyzed seven representative forest and shrubland landscapes in Sicily. These study areas were chosen for their importance in the Sicilian forest panorama. We carried out a diachronic survey on historical and current aerial photos; all the aerial images used to survey the land use/land cover changes were digitalized and georeferenced in the UTM WGS84 system. In order to classify land use, the Regional Forest Inventory 2010 legend was adopted for the more recent images, and the CORINE Land Cover III level used for the older, lower resolut…

Living in future cities: from overbuilding to ecological transition

2022

In contemporary cities the levels of livability and urban quality are less and less optimal. There are various causes: climate and demographic changes, reduction of natural resources, health risks, excessive consumption of soil, increased pollution, impoverishment of populations, lack of employment, transformation of urban space, etc. Evolving cities, increasingly vulnerable, characterized by insecurity, uncertainty and unpredictability, the result of mistakes made in the past. In this context, in planning future scenarios it is necessary to re-examine the governance, the strategies of urban expansion and transformation through new approaches capable of declining innovative concepts such as…

How abrupt change in surface temperature impacts water cycle over France ?

2022

Along with the rapid warming tendency of the last decades over France, a shift in air temperaturehas been detected in 1987/88, delimiting two main climate periods from 1959 to 2019. Evidence of pre- andpost-shift runoff seasonal differences suggest an impact of this abrupt warming on water cycle evolution. Asyearly precipitation slightly evolve during the studied period, evapotranspiration appears to be one of themain drivers of the hydrological cycle evolution. Spring is marked by a strong increase in evaporativedemand, followed in summer by a rise in water stress and a drying of soil water content. Besides temporaldisparities, this local water cycle evolution depicts different spatial res…

Stochastic assessment of climate impacts on hydrology and geomorphology of semiarid headwater basins using a physically-based model

2015

Hydrologic and geomorphic responses of watersheds to changes in climate are difficult to assess due to projection uncertainties and nonlinearity of the processes that are involved. Yet such assessments are increasingly needed and call for mechanistic approaches within a probabilistic framework. This study employs an integrated hydrology-geomorphology model, the Triangulated Irregular Network-based Real-time Integrated Basin Simulator (tRIBS)-Erosion, to analyze runoff and erosion sensitivity of seven semiarid headwater basins to projected climate conditions. The Advanced Weather Generator is used to produce two climate ensembles representative of the historic and future climate conditions f…

What is (not) the point of just transition in food systems?

2022

Food systems are confronted with a low-carbon transition challenge. The need for significant emission reductions in industrial food systems implies significant systemic transformations in food production, processing, and consumption. The wide-reaching impacts of such transformations have evoked public discussion and academic research on just transition in food systems. The undisputable legitimacy of the idea of just transition makes it an attractive concept for all food system actors who might be affected by low-carbon transition policies in direct and indirect ways. Some of the claims that are being made are warranted claims for justice, some merely defend the achieved privileges and benef…

Changes in Climate and Land Use Over the Amazon Region: Current and Future Variability and Trends

2018

This paper shows recent progress in our understanding of climate variability and trends in the Amazon region, and how these interact with land use change. The review includes an overview of up-to-date information on climate and hydrological variability, and on warming trends in Amazonia, which reached 0.6-0.7 °C over the last 40 years, with 2016 as the warmest year since at least 1950 (0.9 °C +0.3°C). We focus on local and remote drivers of climate variability and change. We review the impacts of these drivers on the length of dry season, the role of the forest in climate and carbon cycles, the resilience of the forest, the risk of fires and biomass burning, and the potential “die back” of …
