Analysis of sea temperatures using a four-dimensional spatio-temporal framework has revealed a great number of marine heatwaves occurring globally below the sea surface. These extreme events, which threaten the ecologically important epipelagic zone, have occurred increasingly frequently during the past three decades owing to ocean warming.
Merging flood impact data from Landsat, Sentinel-2, and Sentinel-1 satellites boosts useful flood image coverage from 7% to 66% across all flood types, and would greatly increase the percentage of displaced populations served by high-resolution images
Volcanic eruptions are major natural hazards, but forecasting their activity remains challenging. This Review discusses scientific and monitoring approaches used to forecast magmatic eruptions.
Disaster risk communication traditionally focuses on authorities conveying hazard and risk information to at-risk populations, with little consideration of local community knowledge. To enable risk reduction and resilience, disaster management must forge partnerships with local communities and empower citizen-led initiatives.

Humans and mangroves adapt to conditions arising from subsidence and relative sea-level rise. Quantifying adaptation responses provides an innovative and cost-effective means of characterizing spatial variation in subsidence and relative sea-level rise and delivers critical information for coastal planning.
Rapid urban expansion presents a major challenge to delivering the United Nations Sustainable Development Goals. Urban populations are forecast to increase by 2.2 billion by 2050, and business as usual will condemn many of these new citizens to lives dominated by disaster risk. This need not be the case. Computational science can help urban planners and decision-makers to turn this threat into a time-limited opportunity to reduce disaster risk for hundreds of millions of people.
This season’s wildfires have wreaked havoc for local communities, summer tourists and densely populated cities more than 1,000 km away. International cooperation is urgently needed to ensure humans’ sustainable future with increasing wildfires.
