Kein Fortschritt ohne Risiko
Neulich bin ich zum ersten Mal in einem autonomen Fahrzeug gefahren. Das HOCHBAHN-Forschungsprojekt HEAT testet die Eignung des ersten automatisiert fahrenden Kleinbusses im Hamburger Straßenverkehr. Jede*r kann sich die HEAT-App herunterladen und kostenlos mitfahren. Die Vorstellung, im unbemannten Kleinbus durch die Hamburger HafenCity zu cruisen fand ich aufregend und ein wenig beängstigend. Die Realität war […]
Planting trees to save the climate?
„We plant one tree per product”, an organic chocolate bite company claims that cooperates with Eden Reforestation Projects. “With your help we have already planted 15.000 trees in Columbia”, is written on the website of a company that sells organic cosmetic products in recyclable glass bottles.

2019 on Twitter: Climate activism awakening
Shortly before 2020 is over, we will have a look back at 2019 to map the climate change debate as reflected transnationally on Twitter. Compared with the two years prior, 2019 showed a particular abundance of climate-related tweets: While the total tweets count of 2018 grew by 8% from 2017, the total count of 2019 grew by 70%.

Overstimulated by the news: How to navigate through times of crisis
“Robert-Koch-Institute reports highest daily number of infections”, appears on the screen of my phone. The local newspaper lying on the kitchen table is titled with a similar headline, corona is issue number one in the evening TV-news, and my Instagram feed recommends a livestream of the government´s press conference.
How to talk about climate change – a collection of thoughts and helpful input for non-experts
When did you talk about climate change the last time? And when did you do so with family and friends? Results from our surveys show that on the one hand, the amount of people talking about climate change in their daily lives is rising steadily (see Guenther et al. 2020, in German), but on the […]
Addressing the Nation: Pandemic!
How was the Covid-19 pandemic communicated by different leaders in their televised speeches and why does it matter? Six months have passed since nations of the world have locked-down against the spread of Covid-19.

What is a Climate Model?
Last August, our blogger Shorouk Elkobros explained what a climate model is in this video. One year later, climate models are still an essential tool for understanding global warming. In order to remind us how climate models work, Felix Schaumann has put together his own explanatory video.
After Lunch Posts: Talking Climate Change with Hans von Storch
One of the many privileges of holding a Professorship at the University of Hamburg and being involved in the Cluster of Excellence, which unites researchers from different disciplines around the issue of climate change (see CLICCS website ), is that you have the opportunity to meet and have lunch with highly inspiring and thought-provoking people […]
Why we need airtravel for an accurate weather forecast
Flying is bad for the climate – this is an uncontested fact. However, air traffic is necessary for weather forecasts, as airplanes send live data to weather stations. COVID-19 has caused a massive decline in air travel, hereby affecting the quality of weather forecasts.
Let’s focus on the short-term benefits of long-term climate protection!
A new study by Samset et al. (2020) in Nature Communcations finds that even under strong and sustained mitigation efforts, it will take the climate system until mid-century to demonstrate a discernible cooling response. Unfortunately, we must accept and live with the frustrating fact that the global climate system is a rather gigantic tanker ship […]
