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.
Greenland ice flow likely to speed up: New data assert glaciers move over sediment, which gets more slippery as it gets wetter

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
