5000 years ago, the summer in the Alps were Feuchter – Diepresse.com
This week, the climates with melting glaciers, green parks in the urban area, environmentally friendly mining, CO2 storage and housing freeches.
Dry: Seasonal Dürren archived in Jahrringen
A new study is reconstructing the summer moisture or drought in the Alps over the past 9000 years (Science AdvanceS). The wood samples on which the isotope measurements were carried out come from an archive der Uni Innsbruck. Overall, Tothölzer and rehearsals of living trees from 192 larches and pine from the high -ranking area were used for years. Conclusion: Until 5000 years ago, the summer in the Alps were wetter than today. Since then there has been a long -term trend towards less wet climate. In addition to cool, the small ice age from 1260 to 1860 even brought a pronounced dry phase.

Wet: Tyrol’s glacier melt rapidly there
Even if the global temperature rise is limited to 1.5 degrees Celsius – at best – in the best case – in 2100 by the once large glaciers in the Ötztaler and Stubai Alps are just remaining leftovers. Specifically: Almost three percent of the mass from 2017. In this way, the new calculations are in the journal The Cryosphere of an Austrian-British research team clearly. Especially for smaller ice cream bodies, it becomes foreseeable in the Ostalps. What remains is called Toteis: ice leftovers that no longer have a flow movement and no nutrient area.
Green: Climate adaptation leads to displacement
In order to alleviate the heat summer, urban areas are increasingly greened. What is in principle a welcome measure for people and also the urban biodiversity has a catch: if green areas are expanded, real estate prices usually increase. This displaces those who should actually benefit from the measure. This indicates an investigation of Boku ViennaGeosphere Austria, TU Vienna,, Ait and Joanneum Research there (NPJ Urban Sustainability).
Mining models that take environmental protection seriously: 370 examples of Good Practice from all over Europe are now available.
Our digital age requires intensive mining because electronic devices consume tons of graphite, lithium, cobalt and other raw materials. The productions of wind and solar energy as well as electric cars are also hungry for metals and minerals.
The Montan University Leoben has in EU project « Sumex » 370 examples of sustainability presented in the mineral -winning industry of Europe, as a model for environmental protection. Legal regulations and the responsible handling of resources were assessed. It is important to plan recycling early and to promote the circular economy. Project manager Michael Tost to consider that the transformation of the mining as an environmental sinner is a real chance of now promoting climate protection in the industry. The 370 Good Practice examples Also help to reduce the effects of mining on agriculture and ecology.
A lot of money for technology that can make climate protection cheaper: Houscaps support small engines and charging stations for freight traffic.
On Wednesday there was a prize rain in Vienna: the Houscaps are worth 150,000 euros per victory in the main categories. Overall, the largest private price for application -related research in Austria releases 760,000 euros.
At the TU Graz Flows the money from the university research category into projects from Annette Mützemake the electric small engines cheaper and more efficient. The new construction methods (claw pole engine, circuit board engine) significantly reduce the energy consumption of small vehicles. In the non -university research category won Markus Makoschitz For the « Medusa » project (Montan University Leoben and Ait): It develops multi-megawatt quick charging stations that are relevant for freight transport should switch to renewable energies. The main prize in the category SME received Siegfried Einhellig for TRIC Valve technology, which facilitates heart operations.
Carbon dioxide can be saved in the ground in the long term: if CO2 detects in the groundwater, it drops deeper.

Get rid of carbon dioxide forever? In a complex interaction from Co2-more and more and co2-Färter areas the CO drops2-More water slowly down, so it can be kept in the earth permanently. TU Vienna
To reduce CO2 emissions, is increasingly being used on Carbon Capture and Storage (CCS). Carbon dioxide is to be removed from the air or departed at the location of the origin and stored in the ground. It is unclear what happens in the long term with the CO2. Simulations of an international team with TU-Vienna participation (Marco de Paoli ) Now show that this can be saved permanently (Geophysical Research Letters).
