Voluntary carbon offsets often fail to deliver what they promise
Politics
ETH Zurich
Malte Toetzke calls for more ambitious standards in the voluntary carbon offset market. While this would lead to fewer projects getting funded, the benefit for the climate would be greater overall. 
Why there are no kangaroos in Bali (and no tigers in Australia)
Research
ETH Zurich
Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
Global warming accelerates CO2 emissions from soil microbes
Research
ETH Zurich WSL
When Microorganisms decompose organic material in the soil, they actively release CO2 into the atmosphere. This process is called heterotrophic respiration. A novel model shows that these emissions could surge by up to 40 percent by the end of the century – most significantly in the polar regions.
A contested resource
Research
ETH Zurich
The expansion of hydropower generation often leads to conflicts of interest, both in Switzerland and beyond. Researchers from ETH Zurich are trying to find a basis for compromise that serves the public interest.
A world in flux
Research
ETH Zurich
Heavier rain, longer droughts, melting glaciers: climate change has a dramatic impact on the global water cycle.
Why are forests turning brown in summer?
Research
ETH Zurich WSL
Increasing summer heat and drought are affecting European forests – some years, trees brown prematurely and some even start to die back. Researchers from ETH Zurich and the WSL are showing how exceptional weather conditions over several years are turning forests brown.
