          Abstract

          Considerando que as Alterações Climáticas (AC) - uma das cinco áreas-guia da Estratégia 2020 da Comissão Europeia - são um problema global que requer respostas locais articuladas aos níveis macro, meso e micro; e que a sua compreensão implica a identificação das relações reciprocamente influentes entre a Natureza, a Sociedade e a Cultura; qualquer intervenção - seja no sentido da mitigação das AC, seja no sentido da adaptação às AC - envolve necessariamente essa mesma sociedade, em toda a complexidade das suas dimensões socioculturais e ambientais. Neste artigo, enquadrado pelas teorias compreensivas, refletimos brevemente sobre algumas das inter-relações entre os sistemas climáticos, ambientais e socioculturais e defendemos que as racionalidades leigas, por se enraizarem em tipos e fontes de saber plurais, são um dos pilares para melhor se compreender e lidar com o fenómeno das AC.

          Translated abstract

          Whereas Climate Change (CC) - one of the five prioritary areas of the Strategy 2020 of the European Commission - is a global challenge needing local responses, articulated at the macro, meso and micro levels; and while its understanding entails identifying mutually influential relationships between Nature, Society and Culture, any intervention - either to mitigate or adapt to CC - necessarily involves society itself, in the full complexity of its sociocultural and environmental dimensions. In a world in the midst of a major demographic transition, with a population expected to reach, issues like sustainability, resource use, scarcity and sharing, have been interwoven in the international, regional and local arenas. This paper develops in the light of comprehensive theories. The methodological procedures are based upon desk research and all the work relies on the reflexive notion and today´s ubiquitous complexity. The spirit of this pivotal approach is the interest in knowledge, curiosity for different dimensions of knowledge and how it is (re)produced, articulated and reflected in the relationships of the individual human being, with itself, with other human beings, with other living creatures and with the environment. This papers argues that the lay rationalities, because they take root in various types and sources of knowledge, are one of the pillars to better understand and deal with of CC. Part one of this paper makes a brief reference to ethical implications, preceded by a succinct analysis of the key dynamics and processes, which are considered responsible for the variability and climate change in a diachronic perspective. Part two discusses some of the sustainability issues, with a brief introduction to the pathways and strategies for mitigating and adapting to CC, which have been outlined and lie ahead, linking the global dimension to the local dimension, governments to markets and to civil society. Finally, focusing on lay rationalities, a brief approach is sought regarding the issues of reflexivity, social capital and the 'knowledge-power' concept, keeping in mind that the study of the social reality, which is complex in nature, is always a (de)constructed exercise of dialectics between generalization and specialization.

          Aerosols, climate, and the hydrological cycle.

          Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-made aerosols enhance scattering and absorption of solar radiation. They also produce brighter clouds that are less efficient at releasing precipitation. These in turn lead to large reductions in the amount of solar irradiance reaching Earth's surface, a corresponding increase in solar heating of the atmosphere, changes in the atmospheric temperature structure, suppression of rainfall, and less efficient removal of pollutants. These aerosol effects can lead to a weaker hydrological cycle, which connects directly to availability and quality of fresh water, a major environmental issue of the 21st century.

            Life in extreme environments.

            Each recent report of liquid water existing elsewhere in the Solar System has reverberated through the international press and excited the imagination of humankind. Why? Because in the past few decades we have come to realize that where there is liquid water on Earth, virtually no matter what the physical conditions, there is life. What we previously thought of as insurmountable physical and chemical barriers to life, we now see as yet another niche harbouring 'extremophiles'. This realization, coupled with new data on the survival of microbes in the space environment and modelling of the potential for transfer of life between celestial bodies, suggests that life could be more common than previously thought. Here we examine critically what it means to be an extremophile, and the implications of this for evolution, biotechnology and especially the search for life in the Universe.

              Modeling the Exchanges of Energy, Water, and Carbon Between Continents and the Atmosphere

              Atmospheric general circulation models used for climate simulation and weather forecasting require the fluxes of radiation, heat, water vapor, and momentum across the land-atmosphere interface to be specified. These fluxes are calculated by submodels called land surface parameterizations. Over the last 20 years, these parameterizations have evolved from simple, unrealistic schemes into credible representations of the global soil-vegetation-atmosphere transfer system as advances in plant physiological and hydrological research, advances in satellite data interpretation, and the results of large-scale field experiments have been exploited. Some modern schemes incorporate biogeochemical and ecological knowledge and, when coupled with advanced climate and ocean models, will be capable of modeling the biological and physical responses of the Earth system to global change, for example, increasing atmospheric carbon dioxide.
