“It’s real. It’s us. Experts agree. It’s bad. There’s hope.” In these short sentences, Anthony Leiserowitz from Yale University (USA) summar­ized what we know about climate change and what needs to be done about it: namely to drastically reduce greenhouse gases.

This is true not only for CO2, but also for a group of substances that is less well known outside the scientific community: short-lived climate-impacting substances. These include aerosols, methane, hydrocarbons and soot. In total, they have warmed the atmosphere by just as much as CO2. The latest report of the Intergovernmental Panel on Climate Change (IPCC) has dedicated a separate chapter to them for the first time. Jülich researchers led by Prof. Astrid Kiendler-Scharr, the chapter’s lead author, have been working on these substances for a long time. Our cover story shows how closely interrelated the substances are and how data and models help to understand these interrelations as well as to make predictions for tomorrow’s climate.
