GIS Solutions for Pacific Isles Saluted

…from the Fiji Times

“Geographical Information System and Remote Sensing technologies are sometimes the most practical way to get fast and accurate data on geographic changes in Pacific Island Countries.

“Pacific Islands Applied Geoscience Commission director Cristelle Pratt said many island countries are were using these technologies for vegetation mapping to monitor the amount and extent of coconut, mangrove and other vegetation cover for a range of reasons.

“She said the technology could also help prepare for and deal with natural disasters and climate change.”

Scientists Believe Current Models Do Not Accurately Represent the Sensitivity of Global Temperatures to CO2

…from The Telegraph

“The scientists compared temperature reconstructions from sediments in the ocean floor with a global climate simulation model which aimed to map climate three million years ago.

“Study leader Dr Dan Lunt, from the University of Bristol, said: “We found that, given the concentrations of carbon dioxide prevailing three million years ago, the model originally predicted a significantly smaller temperature increase than that indicated by the reconstructions. This led us to review what was missing from the model.”

“They believe current models do not accurately represent the sensitivity of global temperatures to CO2.

“Climate models used by bodies such as the Intergovernmental Panel on Climate Change often fail to take full account of such effects, said the researchers, whose findings are reported in the journal Nature Geoscience.”

Post Doctoral Research Scientist, Center for Remote Sensing of Ice Sheets

The Center for Remote Sensing of Ice Sheets (CReSIS) located at the University of Kansas is a Science and Technology Center established by the National Science Foundation in 2005. Its mission is to understand and predict the role of ice sheets in sea level change.

CReSIS is currently inviting applications to fill a post-doctoral position in geophysical data management and processing of CReSIS field data.

Required Qualifications

  • Ph.D. in Geography, Geosciences, or related field.
  • Proficient in the use of GIS software tools as evidenced by applicable coursework or work history.
  • Strong written communication skills as demonstrated by application materials and publications.

Ph.D. Graduate Assistantship to Investigate Spatially‐explicit Relationships between Human‐induced Stressors and Environmental Landscape Factors, University of Florida

Fall semester 2010 (mid Aug. 2010)

Soil and Water Science Department, University of Florida, Gainesville, FL.

Applications are invited for the position of a Ph.D. student to investigate spatially‐explicit relationships between human‐induced stressors (such as land use and climate change) and environmental landscape factors (soil, climate, land use / land cover, terrain, geology, and hydrology). A goal of this research is to gain insight into biophysical feedbacks (soil‐vegetation‐water‐atmosphere interactions) and carbon dynamics modulating sequestration and/or losses of carbon in a mixed upland/aquatic ecosystem.

Simulation models (e.g. DayCent) and/or mixed deterministic/stochastic methods will be used to conduct this research.

Desired skills: Ecosystem modeling, database management, geostatistics, statistics, GIS, and environmental sciences or related discipline.

Contact Sabine Grunwald, Associate Professor, sabgru@ufl.edu (352‐392‐1951 x204) and submit a curriculum vitae and letter of intend to apply (pre‐screening).

For admission into the Ph.D. Program offered by the Soil and Water Science Department, University of Florida (http://soils.ifas.ufl.edu) a complete application must be submitted following the guidelines at http://soils.ifas.ufl.edu/academics/application.html.

Application deadline is March 30, 2010

New Book: The Impact of Climate Change on European Lakes

Edited by Glen George

“In this book, scientists from eleven countries summarize the results of an EU project (CLIME) that explored the effects of observed and projected changes in the climate on the dynamics of lakes in Northern, Western and Central Europe. Historical measurements from eighteen sites were used to compare the seasonal dynamics of the lakes and to assess their sensitivity to local, regional and global-scale changes in the weather. Simulations using a common set of water quality models, perturbed by six climate-change scenarios, were then used to assess the uncertainties associated with the projected changes in the climate. The book includes chapters on the phenology and modelling of lake ice, the supply and recycling of nitrogen and phosphorus, the flux of dissolved organic carbon and the growth and the seasonal succession of phytoplankton. There are also chapters on the coherent responses of lakes to changes in the circulation of the atmosphere, the development of a web-based Decision Support System and the implications of climate change for the Water Framework Directive.”

Resource for the Future Launches Global Adaptation Atlas

“The Adaptation Atlas is a dynamic mapping tool, developed by Resources for the Future, in collaboration with a diverse network of partners.

“As adaptation is both a global and a local problem affecting populations and ecosystems around the world, it is natural that responses will be sector-, site-, and population-specific. Success depends on site-specific attention and effective large-scale real-time coordination of impacts and actions. Without this, we run the risk of investing in adaptation measures that could undercut one another.”
