“…At that time, proposing ongoing geological processes challenged the dominant religious rendering of the planet as perfectly created once and for all. This can be contrasted with the more recent conceptions of an unstable Earth, as described by Dahan (2010). In her work, the Earth System of the 1990s is located in a cultural context which embraces chaos as a means of scientific understanding.…”

“…When seen as a living body replete with historically co-evolving organs, syndromes, and fever, it was no longer possible to analyse the components of the Earth System in isolation. As previously recognized by Dahan (2010), the new Earth System vision instead called for a more holistic form of knowledge production and analysis.…”

“…Since 1986, this international programme has invoked 'the Earth System' as a framework with which to unite the physical, biogeochemical, and, later, human sciences into an integrated and predictive framework (Dahan, 2010, Cornell et al, 2012. This thesis is an answer to the call to critically examine the underlying assumptions that facilitate the appearance of the Earth System as a knowable entity ).…”

The Caspian sea (Credit: NASA). ABSTRACT: The complete drying out of the Aral and Caspian seas, as isolated continental water bodies, and their potential impact on the climate and environment is examined with numerical simulations. Simulations use the atmospheric general circulation model (ECHAM5) as well as the hydrological discharge (HD) model of the Max-Planck-Institut für Meteorologie. The dry out is represented by replacing the water surfaces in both of the seas with land surfaces. New land surface elevation is lower, but not lover than 50 m from the present mean sea level. Other parameters in the model remain unchanged. The initial meteorological data is real; starting with January 1, 1989 and lasting until December 31, 1991. The final results were analyzed only for the second, as the first year of simulation was used for the model spinning up. The drying out of both seas leads to an increase in land surface and average monthly air temperature during the summer, and a decrease of land surface and average monthly air temperature during the winter, above the Caspian Sea. The greatest difference in temperature between dry and not dry cases have the same values, about 7-8°C in both seasons, while daily extremes of temperature are much more pronounced. In the wider local/regional area, close to both seas, drying out leads to a difference in average annual temperatures by about 1°C. On a global scale, the average annual temperature remains unchanged and the configuration of the isotherms remain unchanged, except for over some of the continents. In winter, Central Asia becomes cooler, while over Australia, southern Africa, and South America, it becomes slightly less warm. Furthermore, a new heat island occurs in western Sahara during summer.

“…En témoigne l'évolution des rapports d'évaluation que le GIEC publie tous les 5-7 ans environ depuis 1990 comme une base de connaissances factuelles constamment actualisée. Evolution où le volet « impacts, vulnérabilité et adaptation » se voit accorder une importance accrue à l'aune des avancées de la modélisation du système Terre (Dahan, 2010), mais aussi des contributions en sciences humaines et sociales à la compréhension du problème. Ce sont là des évolutions qui jalonnent le processus de négociation.…”

Cartographier la trajectoire de l'adaptation dans l'espace des négociations sur le climat

Les négociations au sein de Convention cadre des Nations Unies sur les changements climatiques (CCNUCC) connaissaient une inflation thématique incessante à l’aune des intérêts et cadrages souvent concurrents des Parties. En témoigne la place acquise par le thème controversé de l’adaptation aux impacts du changement climatique. Cartographier ce phénomène complexe constitue un défi pour l’analyse quali-quantitative des problèmes publics que cet article adresse en présentant et en discutant une expérience de production et visualisation de données sur configuration de l’espace thématique des négociations et son déploiement dans le temps. Par un changement d’échelle et des allers-retours entre visualisation et narration, il est dès lors possible de réduire et redire la complexité pour rendre compte de la trajectoire de l’adaptation. Celui-ci n’est, cependant, qu’un exemple parmi les multiples histoires, fondées sur la modélisation des données, qui peuvent être produites. Ainsi, ce type de visualisations porte un potentiel en tant qu’objet frontière pour discuter les enjeux passés, présents et futurs à l’aune d’une vue synoptique du processus.
