• At Least 23 Killed in Flooding in New York City, New Jersey

    At least 23 people have died across New York City and New Jersey as a result of the historic flash flooding caused by the weather system formerly known as Hurricane Ida. The storm dumped so much rain in New York City that the local National Weather Service issued its first flash flood emergency for NYC and the neighboring city of Newark, New Jersey.

  • Why Buildings Fall — Over Time

    The recent collapse of the condo building in Florida served as a dire warning for the nation’s aging infrastructure problem and the deadly consequences that can result. Researchers explore how time can factor in a building collapse.

  • Hydropower Faces the Future Challenge of Extreme Weather?

    Hydropower has long been seen as a reliable renewable energy source. But during drought and heavy rain, hydropower plants often come to a standstill. Will climate change spell the end for this clean energy alternative?

  • Improving Flood Projections

    Climate change will lead to more and stronger floods, mainly due to the increase of more intense heavy rainfall. In order to assess how exactly flood risks and the severity of floods will change over time, it is particularly helpful to consider two different types of such extreme precipitation events.

  • 2020 Was Among Three Warmest Years on Record

    A new State of the Climate report confirmed that 2020 was among the three warmest years in records dating to the mid-1800s, even with a cooling La Niña influence in the second half of the year. The major indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as sea level, ocean heat content, and permafrost once again broke records set just one year prior.

  • What Caused Heavy Rainfall Which Led to Western Europe’s Severe Flooding

    Mid-July flooding resulted in at least 184 fatalities in Germany and 38 in Belgium and considerable damage to infrastructure, including houses, motorways and railway lines and bridges and key income sources. Road closures left some places inaccessible for days, cutting off some villages from evacuation routes and emergency response. What was the cause of these devastating floods?

  • The Impact of Extreme Waves on Offshore Structures

    Strong storms can trigger steep, breaking waves that slam into platforms and wind turbines with tremendous force. Scientists are studying the behavior of offshore structures subjected to these kinds of waves. Their goal is to increase safety at sea.

  • Wave-Powered SeaRAY Set for Hawaii trial

    Offshore industries, like marine research, fish farming, and mineral mining, often rely on big ships with large crews. Without clean energy to power these vessels, each trip out to sea and back to shore is not only expensive but also carbon intensive. You cannot charge that ship by plugging it into the ocean. Or maybe you can.

  • Cybersecurity Experts Worried by Chinese Firm’s Control of Smart Devices 

    From rooftop to basement and the bedrooms in between, much of the technology making consumer products smart comes from a little-known Chinese firm, Tuya Inc. of Hangzhou.More than 5,000 brands have incorporated Tuya’s technology in their products. Cybersecurity experts are worried, and they urge Washington to limit or ban Tuya from doing business in the United States, in part because a broad new Chinese law requires companies to turn over any and all collected data when the government requests it.

  • New Ways to Assess Climate Change Impacts on Agriculture

    Scientists agree climate change has a profound impact on U.S. agricultural production, but estimates vary, making it hard to develop mitigation strategies. Two agricultural economists take a closer look at how choice of statistical methodology influences climate study results. They also propose a more accurate and place-specific approach to data analysis.

  • Investments in Nature Needed to Stop the Next Pandemic: Experts

    A group of leading scientific experts from the U.S., Latin America, Africa and South Asia released a report outlining the strong scientific foundations for taking actions to stop the next pandemic by preventing the spillover of pathogens from animals to people. Among other findings, the report notes that protecting forests and changing agricultural practices are essential, cost-effective actions to prevent pandemics.

  • Emberometer Gauges Threat of Wildfire-Spreading Embers

    Wildfire fronts spread not only on the ground, but also from above, as the fire launching volleys of glowing embers, also known as firebrands, into the air. These specks of burning debris can glide for up to about 24 miles before landing. They cause up to 90 percent of home and business fires during wildfires.

  • Optical Fibers Detect Earthquakes

    Optical fibers, the underground optical cables that transmit a lot of information at a time, are familiar to us. But few would associate optical fibers with earthquake detection.

  • U.S. Most Widely Felt Earthquake: 10 Years On

    Ten years ago, millions of people throughout the eastern U.S. felt shaking from a magnitude 5.8 earthquake near Mineral, Virginia. No lives were lost, and it was not the strongest earthquake to have occurred in the eastern U.S., let alone the western U.S., but the Virginia earthquake was likely felt by more people than any earthquake in North America’s history.

  • Tracking Water Storage: Improving Water Management During Floods, Droughts

    Researchers have created a balance sheet for water across the United States – tracking total water storage in 14 of the country’s major aquifers over 15 years. With longer-term droughts and intermittent intense flooding expected in the future, particularly in the arid western U.S., there is rising concern about overtaxing water resources in the region, especially for irrigated agriculture.
