Ocean acidification harms cod larvae more than previously thought

New studies on cod larvae show severe organ damages caused by high CO2 concentrations

Understanding nutrient cycling in the low-oxygen ocean

Kiel research team develops basis for quantifying the nitrogen cycling in oceanic oxygen minimum zones

Drought or flooding?  In particular, developing countries like  those in the Sahel region of Africa could benefit from reliable near-term climate predictions. The photo shows a country road in Mali. Foto: NOAA via Wikimedia Commons

Starting signal for Near-term climate prediction

Current ocean and atmosphere data provide basis for more reliable modelling

Extratropical volcanoes influence climate more than assumed

Study shows surprisingly strong cooling after volcanic eruptions in mid and high latitudes
