Climate extremes

How can we check if a simulated heatwave is plausible?

A white thermometer with a red liquid column stands in tan sand. The background shows a bright sun in a blue sky with light clouds.

Extreme heatwaves of unprecedented magnitude are expected to become increasingly frequent in coming decades. These heatwaves come with severe consequences for human health, infrastructure planning, and economic prospects – particularly during events lasting multiple weeks [10]. In recent decades, Western Europe has become a hot-spot for record-breaking and long-lasting heatwaves [9], raising a critical question: …[Read More]

Multi-Risk Forecasting: Operational Reality or Scientific Ambition?

Reflections from a workshop on multi-risk impact-based forecasting and warning systems for weather-related hazards.

  Reflections from a workshop on multi-risk impact-based forecasting and warning systems for weather-related hazards.   With mounting evidence that hazards rarely occur in isolation, the question is no longer whether multi-risk impact-based forecasting and warning systems are needed, but how to build them [1]. Yet, moving beyond single-hazard thinking towards genuinely multi-hazard and then …[Read More]

How scientists support Disaster Risk Reduction (DRR) policies: the example of a European Ultraperipheral Department (Mayotte, the 14th of December, 2024)

How scientists support Disaster Risk Reduction (DRR) policies: the example of a European Ultraperipheral Department (Mayotte, the 14th of December, 2024)

Ultraperipheral European departments like Mayotte are developing regions, often disproportionately exposed to natural hazards and struggling to mitigate the impacts of climate change. The eye of cyclone Chido, the most violent storm to hit Mayotte island in 90 years, engulfed the French Department on the 14th of December 2024. The extensive destruction and massive loss …[Read More]

Taking the risk personally: how perceived flood experience relates to risk perception, sensed coping appraisal, and protective behaviour

Taking the risk personally:  how perceived flood experience relates to risk perception, sensed coping appraisal, and  protective behaviour

The frequency and severity of extreme weather events, such as heavy rainfall, droughts, and storms, are increasing globally, putting societies and infrastructures worldwide at risk [1]. These developments demand effective adaptation measures and ways to enhance societal resilience. Consequently, it is necessary to understand how people perceive and respond to natural hazards. Knowing that the …[Read More]

Navigating the Ongoing and Predicted Disaster of Rio Grande do Sul (Brazil): Career and Insights with Expert Prof. Enner

Severe flooding that left the metropolitan region of Porto Alegre, the capital of Rio Grande do Sul, Brazil, submerged.

We are honoured to hear from Dr. Enner Alcântara, Professor at the São Paulo State University (UNESP) and leader of the Remote Sensing, Spatial Analysis, Environmental Modelling and Natural Disasters Research Group. His research in remote sensing has played a crucial role in recognising, managing and mitigating the impacts of disasters, bringing out significant contributions. …[Read More]

A symphony of uncertainties: exploring the interplay between climate hazards and human societies

A symphony of uncertainties: exploring the interplay between climate hazards and human societies

Climate hazards are manifestations of the Earth’s complex climatic systems. As natural events, they have always occurred, yet changes in the global climate increase the frequency and intensity of extremes and their impact on the built environment and people. Predicting the nature, scale, and location of climate hazards and their complex interplays with anthropogenic factors …[Read More]
