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.

Biomass production in lakes becomes easier to de-termine
The condition of Swiss lakes has improved thanks to stricter protection measures, but less than expected. A new method developed by Eawag for calculating biomass production in lakes provides explanations and a basis for further water protection measures. "No bathing" rules were still imposed on many Swiss lakeshores until the 1980s.
