So far, however, the effects on global production and consumption webs are missing from most assessments. This is a serious deficit, argues Anders Levermann from the Potsdam Institute for Climate Impact Research: “World markets as well as local economies are highly interlinked and rely on global supply chains – adaptation therefore requires a global perspective, not just a local one.”
In a Nature Commentary he proposes a community effort to collect economic data on the new website zeean.net. The aim is to better understand economic flows and to thereby induce a transformation of our supply chains into a stable, climate-smart network that renders our societies less vulnerable to future climate impacts.
“Storms, floods or droughts in one place can have considerable effects all around the world,” Levermann explains. “Take for instance the devastating flood in Thailand in 2011: The local impact was calamitous. Its effect on hard-disk production made it also a global event causing a worldwide shortage for months afterwards.” Flows of materials, communication and energy, their interactions and market dynamics can be subject to climatic extremes – directly but also indirectly via their supply chains. “If the associated risk and vulnerability to climate impacts is to be included into the planning of companies or public institutions, the first step is to identify the vulnerable bottlenecks of our global supply networks,” Levermann says.
Open data and open source algorithms
With the newly launched website zeean.net Levermann aims to kick-start a community effort to generate a global economic networks database of unprecedented comprehensiveness. In order to study the impact of climate extremes, highly detailed information is needed. Similar to the architecture of Wikipedia, any registered and vetted user of zeean.net can enter data about flows between different regional economic sectors, while each piece of information posted will be cross-checked and validated by other users to assess the input quality. The idea is to instigate a community that creates a system of checks-and-balances towards high accuracy of the data. Only open sources will be used and only open source algorithms and analysis tools will be employed to ensure maximum transparency and traceability.
So far, only few research groups around the world compile and use supply chain data. Zeean.net will built on the work of Australian researchers from the University of Sydney, providing information on economic flows between 26 sectors in 186 regions of the world during the past 23 years. With each piece of valid information added, zeean.net will become more accurate and comprehensive, while users see a network evolving that depicts the connectivity of supply chains and enables to identify fragile links. Eventually, the economic data is to be combined with probability assessments of future climate extremes from global and regional climate impact models.
“Our growing insight into climatic extremes needs to be complemented with increasing knowledge about the flows of resources, goods, energy and information that keep our societies running”, Levermann says. “Making this information public might induce self-organized dynamics in our global supply network and will hopefully make our economies more resilient against future climate extremes.”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
