Is Climate Sensitivity Higher Than Believed?
Is Climate Sensitivity Higher Than Believed?
Meta-study on noble gas concentrations in ground water reconstructs climate in the last Ice Age The last Ice Age about 20,000 years ago may have been colder than previous reconstructions of the period's global temperature have led us to believe. An international meta-study to which Werner Aeschbach of the Institute of Environmental Physics at Heidelberg University contributed suggests this may have been the case.

Seasonal Water Resource on the Upper Indus
Seasonal Water Resource on the Upper Indus
Heidelberg geographers draw up full inventory of barely researched aufeis (icing) fields Seasonally occurring fields of aufeis (icing) constitute an important resource for the water supply of the local population in the Upper Indus Basin. However, little research has been done on them so far. Geographers at the South Asia Institute of Heidelberg University have now examined the spreading of aufeis and, for the first time, created a full inventory of these aufeis fields.

Plant provenance influences pollinators
Plant provenance influences pollinators
Insect decline is one of the greatest challenges facing our society. As a result of the destruction of many natural habitats, bees, bumblebees, butterflies, beetles and the like find less and less food. As a consequence, they are barely able to fulfil their role as pollinators of wild and cultivated plants.

Slow start of plate tectonics despite a hot early Earth
Slow start of plate tectonics despite a hot early Earth
Writing in PNAS, scientists from Cologne university present important new constraints showing that plate tectonics started relatively slow, although the early Earth's interior was much hotter than today. In an international collaboration earth scientists at the University of Cologne discovered that during Earth's early history mantle convection on, i.e. the internal mixing of our planet, was surprisingly slow and spatially restricted.

Wind farms are to become quieter
Wind farms are to become quieter
Noise from wind turbines is a constant source of annoyance, despite compliance with emission control standards. But while some people feel heavily burdened by the noises, others hardly notice them. The Inter-Wind research project (Interdisciplinary Analysis and Mitigation Approaches - Residents' Experience of Acoustic and Seismic Wind Turbine Emissions), in which the University of Stuttgart is also involved, is investigating which factors interact in the noise pollution caused by wind turbines and which approaches for mitigation can be considered.

Forces in the Earth's crust determine the height of mountain ranges
Forces in the Earth’s crust determine the height of mountain ranges
Geoscientists show that it is not erosion but an equilibrium of forces in the Earth's crust that controls the "growth" of mountains / Study in "Nature" Which forces and mechanisms determine the height of mountains? Researchers at the University of Münster and the German Research Centre for Geoscience (GFZ) in Potsdam have now found a surprising answer: It is not erosion and weathering of rocks that determine the upper limit of mountain belts, but rather an equilibrium of forces in the Earth's crust.

Asteroid Triggered Mass Extinction at End of Cretaceous Period
Asteroid Triggered Mass Extinction at End of Cretaceous Period
Sixty-six million years ago - at the Cretaceous-Paleogene boundary - nearly three-quarters of all animal species died out, including the dinosaurs. The cause for this has fuelled controversy among scientists for decades. The latest research from an international research team indicates that an asteroid strike was the sole driver of the mass extinction and that volcanic activity did not play a role, even though it certainly had an impact on the climate and the biosphere.
