Displaying 60 of about 75 resultsBy 2050, i.e. in 26 years' time, we will have lost at least 34% of the volume of ice in the European Alps, even if global warming were to stop completely and immediately. This is the prediction of a new computer model developed by scientists from the Faculty of Geosciences and Environment at the University of Lausanne (UNIL), in collaboration with…
Fujitsu today announced the delivery of a new supercomputer system to the Japan Meteorological Agency (JMA) to improve prediction accuracy for typhoons and torrential rains and help authorities develop data-driven plans to provide early warning and evacuation for residents during natural disasters.The JMA will start operations of the new supercomputer s…
For more than a century, and increasingly in the past decade, scientists, academics and higher education institutions in crisis have been supported by international scientific organizations, science academies, representative organizations for higher education, UN agencies and non-governmental organizations. Their ability to offer temporary academic posi…
A reckless experiment in Earth’s atmosphere caused a desert metropolis to flood.That was the story last week when more than a year’s worth of rain fell in a day on the Arabian Peninsula, one of the world’s driest regions. Desert cities like Dubai in the United Arab Emirates (UAE) suffered floods that submerged motorways and airport runways. Across UAE a…
Time15.30-18.00 JST (Room opens 15:15)AboutUNDRR’s private sector group ARISE has always recommended an attitude of constant innovation, taking into account the rapid changes in society, proactively adopting the latest technologies, preparing from new perspectives, in disaster risk reduction actions towards resilience. The theme of this year’s symposium…
Record-setting storms in 2023 filled California’s major reservoirs to the brim, providing some relief in a decades-long drought, but how much of that record rain trickled underground?Shujuan Mao of Stanford University and her colleagues used a surprising technique to answer this question for the greater Los Angeles metropolitan area. They analyzed chang…
After nearly two years’ worth of rain flooded the Dubai region Tuesday, attention quickly shifted to cloud seeding and whether it could have been a factor in the deluge. The geoengineering technology has successfully produced rainfall over the arid United Arab Emirates in the past.[...]But scientists said the downpour was a product of weather patterns t…
The objective of this rapid review of literature is to map the evolution of the impact of the PAR framework in the disasterrisk reduction-related research and practice that has been reported in academic publications. In particular, this review focuses on identifying the core topics on which the PAR model has been used or theoretically considered as an i…
As climate change continues to warm the planet, scientists expect natural hazards such as flooding to increase. Urban flooding can be caused by extreme precipitation events, storm surges, or high tides, with dangerous and expensive consequences for public health and infrastructure.Urban flooding hazards are complicated by the heterogeneity of citie…
The research work presented here aims to provide a detailed investigation of various ways of potentially reducing peaks: adapted barrage operation, polder operation, a combination of both, and the simulation-based development of complex control specifications.The results of the study show that barrage management can contribute to flood reduction on the…
Join us this June in Himeji, Japan for UR24. Over six days, the world’s leading experts and practitioners in disaster and climate risk management and reduction will once again gather to share and explore best practices and innovation in the field. As Japan prepares to commemorate the 30th anniversary of the Great Hanshin Awaji earthquake of 1995, t…
Earthquakes and landslides in the Ionian Sea could trigger tsunami waves as high as 2.5 meters (8 feet) on the southern coast of Italy, according to tsunami models presented at the December 2022 American Geophysical Union Fall Meeting in Chicago and published in a recent report from the Italian Ministry of Ecological Transition. The study focused on the…
Preparing for Atlantic hurricane season is always a priority in the Caribbean, especially when forecasts project high numbers of storms, as they do for 2024. The region's most devastating storm in recent years, Hurricane Maria, struck in September 2017 and inflicted unprecedented destruction on Puerto Rico, Dominica, St. Croix and other islands.Mar…
Every year, the South Asian monsoon season brings heavy rain to over a billion people in the Indian subcontinent between June and September. The rain falls in oscillations: Some weeks see 1 to 4 inches of water, while other weeks are mostly dry. Predicting when these dry and wet periods will occur is critical for agricultural and urban planning, enablin…
Artificial intelligence (AI) can quickly and accurately predict the path and intensity of major storms, a new study has demonstrated.The research, based on an analysis of November 2023’s Storm Ciaran, suggests weather forecasts that use machine learning can produce predictions of similar accuracy to traditional forecasts faster, cheaper, and using less…
