Climate Change

Let’s talk about system change

It’s 2020 and Christoph Kueffer is now into his fifth year of (almost) not flying. Whereas not flying hasn’t been difficult, talking about social change still is, he asserts.

Climate signals detected in global weather

Searched for and found: climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate – but climate change can now be detected in daily weather.

Rainforest preservation through machine learning

Computer scientist David Dao develops intelligent algorithms that use satellite and drone images of rainforests to predict where the next sites of deforestation will be. He will be presenting his research at the climate conference in Madrid today, and will start a pilot project in Chile in January.

Earth’s climate needs our courage

The world is not on track with regard to its CO₂ emissions. In order to achieve the Paris climate targets, we all need to show courage and commitment, says Nicolas Gruber.

Unevenly distributed plankton activity

An international research consortium with ETH participation demonstrates that marine plankton is more diverse in warm oceans than in polar seas, both in terms of species count and the biological activities of the plankton communities. Climate change could lead to a redistribution of plankton in the world’s oceans.

“Science is always a discourse”

A number of researchers have published critical comments in the journal Science about an ETH Zurich study that generated a lot of interest with its quantitative assessment of the technical potential that reforestation holds for reducing CO₂. In the following interview, Professor Detlef Günther, Vice President for Research and Corporate Relations, explains why he welcomes this discourse.
