Many people head to the mountains in the summer to get above the haze of the cities and valleys. A new study finds that the haze could be catching up.

The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some locations. The earth masses removed in this process increasingly blur the shallow water areas and release nutrients and pollutants. Yet, the consequences of these processes on life in the coastal zone and on traditional fishing grounds are virtually unknown. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, urge to focus our attention on the ecological consequences of coastal erosion in the January issue of the journal Nature Climate Change. According to the scientists, an interdisciplinary research program is required, and must involve policy-makers as well as inhabitants of the Arctic coasts right from the onset.

A unique analysis of the famous reef during rapid sea-level rise at the beginning of the Last Interglacial found it almost died. The PhD research shows the reef is resilient but questions remain about cumulative impacts.

New research conducted by the University of Adelaide shows there is no greater risk of Salmonella contamination in the production of free range eggs due to hot summer weather, compared with other seasons.

About 15,000 years ago, the ocean around Antarctica has seen an abrupt sea level rise of several meters. It could happen again. An international team of scientists with the participation of the University of Bonn is now reporting its findings in the magazine Nature Scientific Reports.
