Climate change considerably threatens Europe's beech forests
Tree ring analyses reveal growth declines over recent decades / Researchers expect further, even drastic declines, especially in southern Europe 16 March 2022 Beech forests in Europe are severely threatened by climate change, particularly in southern European countries, but also in central Europe. Models project severe beech growth declines over the next 70 years - ranging from 20 percent to perhaps more than 50 percent depending on the climate change scenario and the region in question.

Stalagmites trace climate history and impact from volcanic eruptions
Stalagmites trace climate history and impact from volcanic eruptions
Research team including Göttingen University studies volcanic impact on ecosystems in Patagonia The soils and vegetation of Patagonia's fjord regions form a unique and highly sensitive ecosystem that is closely linked to marine ecosystems, sediment deposition and carbon storage in the ocean. A research team, including the University of Göttingen, has been working on reconstructing the climate history of this region in this extremely wet, rainy and inaccessible fjord and island zone of the Patagonian Andes in southern Chile.

Microbes living under extreme conditions
Microbes living under extreme conditions
At the mouth of the Rio Tinto in southwestern Spain, acidic river water - polluted with heavy metals from ore mining and mineral weathering - mixes with the salt water of the Atlantic Ocean. Here, microorganisms that love such extreme conditions form a unique community. They live in water as acidic as vinegar, are resistant to high salinity, and some also cope very well with high levels of toxic metals.

How Climate Change is Destroying Arctic Coasts
How Climate Change is Destroying Arctic Coasts
Global warming is causing permafrost in the Arctic to thaw and sea ice to melt. As a result, coasts are less protected and are being eroded, while carbon stored in the soil and carbon dioxide are being released into the ocean and atmosphere. In a first, researchers at Universität Hamburg have now calculated the future scale of these processes for the entire Arctic.

Understanding tomorrow’s Arctic
Hundreds of international researchers are currently analysing observations from the year-long MOSAiC expedition, during which hundreds of environmental parameters were recorded with unprecedented accuracy and frequency over a full annual cycle in the central Arctic Ocean. Three review articles on the MOSAiC programmes for atmosphere, snow and sea ice, and ocean have now been published in the journal Elementa, highlighting the importance of looking at all components of the climate system together.

Mount Etna's exceptional CO2 emissions are triggered by deep carbon dioxide reservoirs
Mount Etna’s exceptional CO2 emissions are triggered by deep carbon dioxide reservoirs
The transport of carbon dioxide stored in the Earth's lithospheric mantle beneath the Hyblean Plateau in southern Italy at a depth of approximately 50 to 150 kilometres is responsible for the exceptionally large CO2 emission of Mount Etna. That is the result of research conducted by an international team of geologists, including researchers from the Universities of Florence (Italy) and Cologne , and from the Istituto di Geologia Ambientale e Geoingegneria of the Italian National Research Council (CNR).

Swaying mountains
Swaying mountains
The Matterhorn appears as an immovable, massive mountain that has towered over the landscape near Zermatt for thousands of years. A study now shows that this impression is wrong. An international research team has proven that the Matterhorn is instead constantly in motion, swaying gently back and forth about once every two seconds.

Analysis of Mars’s wind-induced vibrations sheds light on the planet’s subsurface properties
Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet's surface. These findings were gained in the framework of NASA's InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners, including the University of Cologne, collaborate.

Fluid-Mineral Interactions in Rock
Fluid-Mineral Interactions in Rock
Heidelberg geoscientists test new methods to understand the effects of rupture processes in the Earth's interior Spontaneous mineral growth and dissolution in the rock of the Earth's crust, until now observed only by chance and never described or systematically studied, are the focus of a new research project at Heidelberg University.

Oldest footprints of pre-humans identified in Crete
Oldest footprints of pre-humans identified in Crete
The oldest known footprints of pre-humans were found on the Mediterranean island of Crete and are at least six million years old, says an international team of researchers from Germany, Sweden, Greece, Egypt and England, led by Tübingen scientists Uwe Kirscher and Madelaine Böhme of the Senckenberg Center for Human Evolution and Palaeoenvironment at the University of Tübingen.

Bombardment of Planets in the Early Solar System
Bombardment of Planets in the Early Solar System
Studies of the asteroid Vesta provide new findings on the formation of Earth-like planets The largest asteroid in our Solar System - Vesta - was exposed to an extensive series of impacts by large rocky bodies much earlier than previously assumed. Researchers of an international collaboration, including earth scientists of Heidelberg University and Freie Universität Berlin, reached this conclusion based on analyses of Vesta meteorites, numerical simulations, and observations carried out with the space probe Dawn in 2011 and 2012.

Nightmare Without End
Study with participation from Heidelberg shows that supervolcanoes remain dangerous long after erupting Besides cosmic impacts, supervolcanic eruptions rank among the worst catastrophes in the Earth's history, like that of the Toba volcano on Sumatra (Indonesia) approximately 75,000 years ago, which affected all of Southeast Asia and beyond.

Virtual experiments: Münster University geophysicists research the Earth’s origins on the computer
Although Dr. Christian Maas does his research only on the computer, it's sometimes as if he were standing in a laboratory. "I do experiments," he says. By means of his virtual experiments, geophysicist Maas is investigating a question that couldn't be answered in any lab in the world: the question of the how the Earth came into being.

51,000-year-old Engraved Giant Deer Bone Discovered in the Harz Mountains
Artifacts found in the Einhornhöhle cave in northern Germany are the subject of a research project involving experts from Freie Universität Berlin and shine a light on the cognitive abilities of our Neanderthal ancestors No 150/2021 from Aug 04, 2021 A discovery made by a research team in a cave in Lower Saxony, northern Germany, suggests that Neanderthals were not merely a primitive subspecies of archaic humans - a commonplace belief ever since their first fossil remains were found in the nineteenth century.

How climate change and fires are shaping the forests of the future
Tracking future forest fires with AI As temperatures rise, the risk of devastating forest fires is increasing. Researchers at the Technical University of Munich (TUM) are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will have on forest ecosystems.

The inner beauty of hailstones
The inner beauty of hailstones
The Tübingen region has recently seen hailstorms that brought back memories of the devastating storm of 2013. At that time, billions of dollars in damage were caused, and the damage from the most recent storms is still being assessed. Despite all the trouble hailstones cause, they also possess a previously unknown inner beauty.

Continuous activity of small earthquakes makes mountains grow
Continuous activity of small earthquakes makes mountains grow
From a human perspective, earthquakes are natural disasters - in the past hundred years, they have caused more than 200,000 deaths and enormous economic damage. Mega-earthquakes with a magnitude of nine or higher on the Richter scale are considered a particular threat. Yet the inconceivable energy released in these events doesn't seem to affect the uplift of mountains, according to a new study by geoscientists at the University of Tübingen.

Long-term Himalayan Glacier Study
Heidelberg University geographers combine historical images and maps with current data The glaciers of Nanga Parbat - one of the highest mountains in the world - have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study conducted by researchers from the South Asia Institute of Heidelberg University.
