Risk identification and assessment

A qualitative or quantitative approach to determine the nature and extent of disaster risk by analysing potential hazards and evaluating existing conditions of exposure and vulnerability that together could harm people, property, services, livelihoods and the environment on which they depend.

More accurate El Niño Southern Oscillation forecasts developed

A team of researchers have now assessed the likelihoods of different types of ENSO events developing in succession, and the results have enabled them to deliver more accurate and timely forecasts, giving communities more time to prepare and plan.

Climate change and high exposure increased costs and disruption to lives and livelihoods from flooding associated with exceptionally heavy rainfall in Central Europe

In mid September 2024 a very large region in Central Europe, including Poland, Czechia, Austria, Romania, Hungary, Germany and Slovakia experienced very heavy rainfall, breaking local and national rainfall records over the period of four days.

1 in 2 El Niño events could be extreme by mid-century

In a new study published Sep. 25 in the journal Nature, a CU Boulder climate scientist and collaborators reveal that the planet could see more frequent extreme El Niño events by 2050 if greenhouse gas emissions continue to increase.

Harvests, wildfires, epidemics: How the jet stream has shaped extreme weather in Europe for centuries

Scientists have observed a trend showing the jet stream is gradually shifting northward, independent of its seasonal or more short-term variations. The findings also set a precedent for a future trajectory of jet stream variation and extreme weather.

Why do the largest continental earthquakes nucleate on branch faults?

New research suggests branch faults serve as on-ramps to major fault superhighways. The key to this phenomenon might be that the branch fault ruptures faster than seismic waves can travel — the equivalent of breaking the sound barrier in Earth’s crust.

Abrupt intensification of northern wildfires due to future permafrost thawing

A study shows that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and Arctic regions of northern Canada and Siberia.

Channel conveyance and flood risk: Are current models missing the mark?

Channel conveyance is calculated by measuring the depth and width of a river channel. Most hydrologic models assume that channel conveyance is constant, but this is based on periodic measurements that can be taken decades apart.
