The formation of large meteorite craters is unraveled
About 66 million years ago, a meteorite hit the Earth of the Yucatan Peninsula in what is now Mexico. This event triggered a mass extinction that eradicated approximately 75 percent of all species and ended the era of dinosaurs. Like Ulrich Riller of the Institute of Geology of the University of Hamburg and co-workers report in "Nature", the hitherto mysterious formation of the crater and its mountaneous peak ring.

Mountains in motion
Mountains in motion
The Alps are on the go: The mountain range drifts northwards an average of one-half millimeter every year and rises 1.8 millimeters. However, there are strong regional variances. In order to follow these movements, researchers at the Technical University of Munich (TUM) have evaluated measurements made by more than 300 GPS antennas over a period of twelve years.

New study puts a figure on sea-level rise following Antarctic ice shelves' collapse
New study puts a figure on sea-level rise following Antarctic ice shelves’ collapse
An international team of scientists has shown how much sea level would rise if Larsen C and George VI, two Antarctic ice shelves at risk of collapse, were to break up. While Larsen C has received much attention due to the break-away of a trillion-tonne iceberg from it last summer, its collapse would contribute only a few millimetres to sea-level rise.

Mediterranean Climate as pacemaker for Glacier Formation in Europe
Ice ages are recurring phenomena in Earth's recent geological history, and the resulting glacier advances significantly shaped the European landscape. An international research team led by Dr Stefanie Kaboth from the Institute of Earth Sciences at Heidelberg University has now shown that the extent of glaciation in Western Europe was largely driven by the advection of warm seawater towards Europe's Atlantic coast, which raised precipitation on the continent.

Polar ice may be softer than we thought
Polar ice may be softer than we thought
Tübingen and international researchers investigate ice flow speed in northern Greenland, correcting models predicting sea level change Ice is a material that can flow like a very viscous liquid. In the polar ice sheets, it flows towards the oceans under its own weight. Knowing how fast the ice flows is of crucial importance to predict future sea level rises, particularly under changing climate conditions.

Possible for the first time: reliable three-month forecasts for European winters
Possible for the first time: reliable three-month forecasts for European winters
Thanks to a novel method, the quality of seasonal forecasts for the winter in many parts of Europe can now be significantly improved. To date, reliable forecasts could mostly be made for the Tropics. A team led by Dr. Mikhail Dobrynin and Prof. Johanna Baehr from Universität Hamburg's Center for Earth System Research and Sustainability (CEN) has now released its findings in Geophysical Research Letters.
