Along fault zones, the tectonic movements result in increasing tension that in turn c…
On February 20, a dedicated team of researchers presented a new high-resolution calving front dataset from 149 glaciers in Svalbard spanning from 1985 to 2023. This innovative dataset, featured in the Earth System Science Data journal, offers an important tool to better understand the mechanisms behind glacier calving, or the breakup of icebergs, w…
This study uses a crowd-sourced municipal call database to characterize the spatial distribution of floodrisk in Detroit, MI. Call data, including dates and addresses, were obtained from the City of Detroit Department of Public Works for 2021. Calls were mapped and aggregated to census tract counts and merged with neighborhood-level data. Associations o…
Some researchers have recently proposed the construction of artificial structures – submarine curtains or walls – to stop the warming ocean from getting to the most rapidly melting glaciers in West Antarctica.If effective, these interventions could save trillions of dollars in avoided coastal impacts.But such a large-scale operation in one of the most i…
Year after year, record-breaking air temperatures and heat waves are reported nationwide. In 2023, Death Valley, California experienced temperatures as high as 129°F — the highest recorded temperature on Earth for the month of June—and in July, Southwest states experienced prolonged heat waves where temperatures did not drop below 90°F. This is es…
In American Samoa, the sea is rising 4 times faster than the global average. And an ongoing project has shown that land subsidence is to blame: The crust is relaxing after an earthquake and tsunami in 2009, compounding the effects of climate change.“The water is getting higher because the volume of water is getting bigger, but also because the land is g…
Displacement is a major impact of the climate crisis in Pakistan. "In a flood emergency access to the ‘digital ecosystem’ provided by mobile devices can be critical for individual safety, but not everyone has equal access," explain IWMI’s Kanwal Waqar and Alan Nicol.Pakistan’s devastating losses from recent disastrous floods and drou…
An unusual boost in plant productivity can foreshadow severe soil water loss. NASA satellites are following the clues.Flaring up rapidly and with little warning, the drought that gripped much of the United States in the summer of 2012 was one of the most extensive the country had seen since the yearslong Dust Bowl of the 1930s. The "flash drought,"…
UNDRR Asia Pacific office, along with Asia Pacific Science Technology Advisory Group (AP STAG) and IIT (Indian Institute of Technology) Roorkee will co-organize Asia Pacific Science Technology Conference on Disaster Risk Reduction (APSTCDRR) on 11-13 July in IIT Roorkee, India. This conference is considered a stakeholder meeting who focuses on role of s…
With the potential for flooding during present-day winter storms and sea level rise continually inching up on San Francisco Bay Area communities, a team of scientists and engineers have created a new computer model that can inform key decision-making and guide flood prevention efforts both now and in the future. The model can be accessed free-of-ch…
In the summer of 2021, travelers in Colorado's Glenwood Canyon were safely evacuated before massive mounds of mud and rocks buried highways and destroyed bridges, thanks to a debris flow warning system developed in part by the U.S. Geological Survey. The system alerted Colorado Department of Transportation officials to intense rainfall events, providing…
The world is making big bets on technology's role in the climate crisis. Across the globe, scientists and technologists are pushing for the next wave of breakthroughs in climate adaptation and mitigation.And there is reason for optimism: recent years have seen meaningful progress, from weather forecasting to industrial decarbonization.History shows that…
Beginning annually on June 1, hurricane season poses a major threat to Texas coastal communities, causing both physical and financial damage to the areas they hit. This damage can be staggering; when Hurricane Harvey hit in 2017, it cost Galveston $132.73 billion in damages. Texas A&M University researchers have collaborated to understand the impact…
The aim in this loss calculations is to estimate the total sum of fatalities that are likely as a measure of the extent of earthquake disasters. The number of fatalities and injured was calculated, using the computer code QLARM and its data set and assuming information about the Irpinia 1980 earthquake became available in near-real-time. The articl…
Government scientists have cooked up a new concept for how to potentially cool an overheating Earth: Fiddle with the upper atmosphere to make it a bit drier.[...]Water vapor—water in its gas form—is a natural greenhouse gas that traps heat, just like carbon dioxide from burning coal, oil and gas. So researchers at the National Oceanic and Atmospheric Ad…
