Bamako, 14 September: It is almost 20 years since the historic United Nations Conference on Sustainable Development, held in Rio de Janeiro in June 1992, alerted Governments and citizens to critical human development issues and made specific demands of countries. Among the issues fuelling the discourse then, was the global sounding off o…
As the world celebrates World Humanitarian Day, UNISDR, the strategic arm of the United Nations working on disaster risk reduction, recognizes the valuable contribution of humanitarian workers who risk their lives everyday to help others, whilst emphasizing their crucial role in reducing disaster risk.
“On this day we recognize the importance of humani…
In this publication researchers conduct an appraisal of the Glacial lake outburst flood (GLOFs) risks by combining high-resolution satellite images, case-by-case high-precision GLOF modeling, and detailed downstream exposure data. Glacial lake outburst floods (GLOFs) are among the most severe cryospheric hazards in the Third Pole, encompassing the Tibet…
An intense heatwave gripping South and South-East Asia since late March comes as no surprise to leading meteorologists who have been warning of steadily rising temperatures in the Indian Ocean.Temperatures in the Philippines and Thailand have topped 50C this month, while Bangladesh has recorded almost 30 days of heatwaves, leading to deaths from heatstr…
There is likely to be a significant increase in the danger of wildfires through the 21st century. Indeed, the expectation is that by 2100 the danger will be high even in regions where it is very low today. Those are the findings of a study by Julia Miller, a PhD student in the Hydrology & Climate Impacts in Mountain Regions research group…
One of the big contributors to the record-breaking global temperatures over the past year -- El Niño -- is nearly gone, and its opposite, La Niña, is on the way.Whether that's a relief or not depends in part on where you live. Above-normal temperatures are still forecast across the U.S. in summer 2024. And if you live along the U.S.…
Extreme weather and climate events, such as droughts, heat waves, and rainstorms, pose serious threats to human health, agricultural production, and energy supplies. These events often occur at the same time, and such "compound extreme events" can cause far more damage than any one single event.Climate scientists from the research group of Prof. Aihui W…
Weather instabilities in the Arctic and changes in air temperature in distant regions such as California and Southwest China are linked, an international team of researchers reveals. Their study has been published in Nature Communications. The scientists also demonstrate that increased day-to-day irregularities in Arctic sea ice cover are caused by the…
This study developed a systematic record of the direct impacts of Medicane Ianos on the Ionian Islands, in Greece, as a characteristic case study illustrating the potential effects of such an extreme event on a developed Mediterranean coastal area. Despite being relatively rare, Mediterranean tropical-like cyclones, also known as Medicanes, induce signi…
The disappearance of the ephemeral lake has made earthquakes along the San Andreas Fault even more unpredictable. In the arid expanse of what is today Southern California, a vast lake once waxed and waned. Lake Cahuilla spanned thousands of square kilometers before drying away to nothing and then reappearing in a decades-long cycle that repeated ov…
Climate change has already made extreme precipitation in California twice as likely, part of a trend projected to continue through 2100.
Extreme storm sequences are projected to generate 200% to 400% more runoff by the end of the century.
Today’s study is the first part of ArkStorm 2.0, a scenario to prepare for catastrophic flooding in the western…
A team led by Kristen Guirguis, a climate researcher at Scripps Institution of Oceanography at UC San Diego, found evidence that the risk of hazardous weather is increasing in the Southwest.
The researchers investigated the daily relationships among four major modes of weather affecting California. How they interact governs the formation of weather eve…
Researchers attempting to help predict how the wildfire hazard will change due to various factors over the next several decades have some good news, and some bad news. Good news is, wildfire occurrence and intensity will likely decrease in several locations in the future. The bad news: decreases may not occur for another 50 years, and wildfire hazard wi…
Regions burned by wildfires are more susceptible to debris flows, a type of fast-moving, destructive landslide
Researchers adapted a hydrology model to simulate how rainwater moves over burned areas
Resulting model shows which areas are more likely to experience debris flows based on vegetation, topological features and where it rains hardest
Simul…
The frequency of thunderstorms in some fast-growing African coastal cities has doubled over the past 30 years, with much of this increase linked to the impact of deforestation on the local climate, a study has found.
It is widely known that removal of vegetation increases rainwater runoff and the risk of mudslides, which happened in Sierra Leone’s capi…
