A new tool is helping researchers simulate erosion and climate change, turning data into action.

A study published on Jan. 14 in Nature shows that many of the world’s major river deltas are sinking faster than sea levels are rising, potentially affecting hundreds of millions of people in these regions.

They have been described as the water towers of the world, and with good reason.

Marine heatwaves (MHWs) are periods of unusually warm sea temperatures, recognised as one of the fastest emerging climate-related drivers of change in the ocean.

When engineers and planners design roads, bridges and dams, they rely on hydrological models intended to protect infrastructure and communities from 50- and 100-year floods. 

A new international analysis published in Advances in Atmospheric Sciences on 9 January finds that the Earth's ocean stored more heat in 2025 than in any year since modern measurements began.

New observations help explain why the southern hemisphere is warming less quickly than the northern hemisphere.

"Proxies" in geologic record show rainfall was more intense, but less regular during the Paleogene.

The rise in wildfires globally brings into sharp focus how such disasters increasingly threaten our health and security. One question many people ask is how poor air quality could be harming their health.

Researchers from the IIASA Biodiversity and Natural Resources Program are involved in the recently launched EU-funded Trees4Adapt project.
