These questions will be discussed during the international “Open Science Conference on Climate Extremes and Biogeochemical Cycles in the Terrestrial Biosphere: impacts and feedbacks across scales” in Seefeld, Austria, from 2nd to 5th April 2013, hosted by the University of Innsbruck.
More than 150 scientists from over 20 different countries will meet to discuss the responses of ecosystems to climate variability and weather extremes, based on experimental evidence and modeling of the biosphere-climate system.
Rising atmospheric greenhouse gas concentrations not only lead to global warming but also to increased climate variability and extreme weather situations. Within the past decade an exceptionally high number of extreme heat waves occurred around the globe: Record breaking temperatures hit central Western Europe in 2003, causing a large number of fatalities due to heat stress. In South-Eastern Europe dramatic wildfires ravaged in 2007, especially in Greece. Together with huge forest fires, an extraordinary heat wave with record temperatures led to a high and long-lasting air pollution in western Russia in 2010. The drought in 2011-2012 was reported to be one of the most severe ever recorded in the United States, with an economic loss of billions of dollars and heavy crop failures.
Not only severe droughts and heat waves but also extreme precipitation and windstorms can impact the structure, composition, and functioning of terrestrial ecosystems. The importance of extreme climatic events for the carbon balance became clear after the 2003 heat wave in Central and Southern Europe. Triggered by this month-long anomaly, the ecosystems lost as much CO2 as they had absorbed from the atmosphere through the previous four years under normal weather conditions.
Recent evidence also suggests that extreme weather may influence the carbon balance of our terrestrial biosphere such that it accelerates climate change. Co-organizers Dr. Michael Bahn, Associate Professor at University of Innsbruck, and Dr. Markus Reichstein, Max-Planck Director at the Max-Planck Institute for Biogeochemistry, Jena, state unanimously: “Several lines of evidence indicate water-cycle extremes, in particular droughts, being a dominant risk for the carbon cycle in large parts of Europe. The largest and most diverse and enduring effects of extreme events are expected in forests.”
The “Open Science Conference on Climate Extremes and Biogeochemical Cycles in the Terrestrial Biosphere” is a joint initiative of the EU supported FP7 research project CARBO-Extreme, the US-based network INTERFACE, and the international activity iLEAPS funded by the International Geosphere-Biosphere Program. CARBO-Extreme analyses the impact of climate extremes on the terrestrial carbon cycle. The University of Innsbruck is a partner in the CARBO-Extreme project which is coordinated by the German Max Planck Institute for Biogeochemistry in Jena.

International team of scientists develops new feedback method for optimizing the laser pulse shapes used in the control of chemical reactions
In many ways, traditional chemical synthesis is similar to cooking. To alter the final product, you can change the ingredients or their ratio, change the method of mixing ingredients, or change the temperature or pressure of the environment of the ingredients.
Like an accomplished chef, chemists have become very skilled ...
A genetic defect protects mice from infection with influenza viruses
A new study published in the scientific journal PLOS Pathogens points out that mice lacking a protein called Tmprss2 are no longer affected by certain flu viruses.
The discovery was made by researchers from the Helmholtz Centre for Infection Research (HZI) in Braunschweig in collaboration with colleagues from Göttingen and ...
The Light: Global study gets underway with online user survey
Light has a fundamental impact on our sense of well-being and performance. In cooperation with Zumtobel, a supplier of lighting solutions, Fraunhofer IAO has launched a global user survey of lighting quality in offices. The objective is to identify the best lighting conditions for a variety of spaces and lighting ...
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
