The Climate Change and Environmental Systems (ZEPHYRUS) is the Portuguese leading team on geographical analysis of climate change and environmental systems, joining several working areas and recognized international experts. The research group joins ANTECC and CLIMA teams of CEG. The key focus are the interactions between a changing climate, environmental systems and human activities at various scales and in different regions across the Earth. The research is organized into three main subject areas: climatology, biogeography and geocryology.

a) Climatology research targets are framed by five main topics: i) Urban Climatology; ii) History of climate; iii) Climate risks and responses; iv) Bioclimatology; v) Applied climatology, such as tourism and climate change, wind and nautical sports, wind power resources and energy efficiency, local climates and agriculture. Climate and environmental guidelines for planning have been developed in collaboration with planners in several Municipalities, to support policy-maker decisions;

b) Biogeography has focused on the study of: i) consequences of environmental changes (mainly global warming) in plant communities; ii) the impact of the sea level rise on coastal ecosystems; iii) land use changes in the flora and vegetation structure and conservation status. Influences of physical and human activities in the natural communities and landscape dynamics have been studied. Characterization of chloroplast genes was used to study peat bogs’ present ecological conditions in comparison with paleoenvironmental settings, allowing to reconstruct migration routes and glacial refugees of their flora and vegetation.

c) Geocryology – research has focussed on the dynamics of Polar and cold mountain environments in a changing climate, on: i) mapping, monitoring and modelling permafrost and the active layer; ii) monitoring geomorphodynamics of cold environments; iii) remote sensing of snow and polar vegetation; and iv) paleoenvironmental reconstruction of cold environments. The overarching objective is contributing to research on the dynamics of cold environments and linkages to the Global Climate System. For this, cryospheric variables and conditioning factors are being monitored and modelled, with a focus in the Antarctic Peninsula region. The objectives are framed within the Global Terrestrial Network for Permafrost (GTN-P – IPA/WMO) and the SCAR/IPA Expert Group on Permafrost, Soils and Periglacial Environments (G. Vieira, Co-Chair). Together with CCMAR and IMAR, the Geocryology team coordinates the Portuguese Polar Programme (PROPOLAR) and is responsible for managing national logistics in the Antarctic (http://www.propolar.org)
