IIASA Director General Hans Joachim (John) Schellnhuber is featured in the new documentary Hirschhausen will zum Papst (Hirschhausen wants to meet the Pope), produced by Germany’s public broadcaster ARD.

The documentary explores the intersection of climate change, ethics, and global responsibility through conversations surrounding the legacy of Pope Francis and his environmental advocacy.

The film follows German physician and science communicator Eckart von Hirschhausen as he examines the growing moral and societal dimensions of the climate crisis. Schellnhuber appears as one of the featured scientific voices (at minute 8:55), contributing perspectives on climate science, sustainability, and the urgent need for transformative action.

The documentary highlights the increasing importance of dialogue between science, society, and global institutions in addressing planetary challenges.

Amazon understory forests show short-term boost in CO₂ uptake – but this comes at a cost

Tropical forests are one of the planet's most important carbon sinks – often also called "the lungs of the Earth". But their future in a high-CO₂ world remains uncertain. IIASA researchers contributed to a new study, which suggests even small understory trees in the Amazon may initially buffer climate change more strongly. Their long-term capacity to store carbon could, however, be restricted by nutrient availability, highlighting the vulnerability of these ecosystems under future climate conditions.

Trees4Adapt project to address risks from climate change and biodiversity loss through tree-based solutions

Researchers from the IIASA Biodiversity and Natural Resources Program are involved in the recently launched EU-funded Trees4Adapt project. The project focuses on tree-based solutions for climate adaptation, aiming to strengthen Europe’s adaptation and resilience to climate change in a way that supports people and nature.
