• Scientists Warn of Weather Extremes as “New Normal”

    Scientists warned that faster and stronger climate change is threatening the Earth and humankind as extreme weather has become the “new normal,” according to a report presented to UN climate chief. The report found that climate change is forcing people to reconsider the notion of an extreme event. What was once considered unlikely or rare – is becoming part of the “new normal.”

  • New Research Center Will Fight Misinformation

    On 3 December, the University of Washington launched the Center for an Informed Public (CIP). The CIP, an interdisciplinary center housed in UW’s Information School, will use applied research to engage with the public through community partners such as libraries to confront the misinformation epidemic. “If we care about common goals — things like safe communities, justice, equal opportunity — we have to care also about facts, truth and accuracy,” UW President Ana Mari Cauce said. “Misinformation can be weaponized. It has been weaponized to divide us and to weaken us.”

  • Flash Flooding Is a Serious Threat in the U.K. – Here’s How Scientists Are Tackling Its Prediction

    Surface water flooding is what happens in built-up areas when heavy rainfall has nowhere to go. Unable to enter a watercourse or drainage system, the water instead flows over the ground causing flash flooding. Unlike river and coastal flooding, which can be widespread, surface water flooding presents unique challenges because it’s difficult to predict the location, timing and impact of what are typically localized events. As the climate changes and urban populations grow, the number of people at risk of surface water flooding increases.

  • Arctic “Ice Management” Delays, but Not Negate, Climate Change Effects

    According to a much-debated geoengineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers say that the approach could potentially put off ice-free Arctic summers for a few more decades, but beyond that, the Arctic the massive campaign wouldn’t produce any meaningful cooling effect.

  • Robotics Researchers Have a Duty to Prevent Autonomous Weapons

    Robotics is rapidly being transformed by advances in artificial intelligence, and the benefits are widespread. But our ever-growing appetite for intelligent, autonomous machines poses a host of ethical challenges.

  • Early Climate Models’ Global Warming Predictions Were Spot-On

    Climate skeptics have long raised doubts about the accuracy of computer models that predict global warming, but it turns out that most of the early climate models were spot-on, according to a look-back by climate scientists.

  • Invasive Grasses Are Fueling Wildfires Across the U.S.

    People alter fire regime patterns by adding ignition sources, such as campfires or sparking power lines; suppressing fires when they develop; and introducing nonnative invasive plants. My research suggests that nonnative invasive grasses may be fueling wildfires across the United States. Some fires are occurring in areas that rarely burn, like the Sonoran Desert and the semiarid shrublands of the Great Basin, which covers most of Nevada and parts of five surrounding states. In the coming months, some of the grasses that help feed these blazes will germinate, producing tinder for future fires.

  • Bolstering Florida’s Flood Resilience

    Researchers from Florida Atlantic University’s College of Engineering and Computer Science have received a $1,688,955 grant from the Florida Division of Emergency Management (FDEM) for a pilot project to create a framework for their Watershed Planning Initiative. In 2017, Florida had 1.7 million flood insurance policies included in the Presidential Emergency Declaration. This is roughly 35 percent of all National Flood Insurance Program policies across the country and serves as an indicator of the impact of Hurricane Irma on the National Flood Insurance Program.

  • The Past Decade Saw Exceptional Global Heat, High-Impact Weather

    The year 2019 concludes a decade of exceptional global heat, retreating ice and record sea levels driven by greenhouse gases from human activities. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods are almost certain to be the highest on record. 2019 is on course to be the second or third warmest year on record, according to the World Meteorological Organization.

  • Grid Reliability under Climate Change

    Researchers are using a new modeling approach for infrastructure planning of a long-term electricity grid that considers future climate and water resource conditions.  Those conditions include reduced hydropower production as well as reduced availability of cooling water due to reduced streamflow and increased streamflow temperature.

  • Underwater Telecom Cables to Be Used as Seismic Detection Network

    About 70 percent of Earth’s surface lies under the sea, which means that, until now, most of the Earth’s surface had been largely without early-warning seismic detection stations. Scientists say that fiber-optic cables that constitute a global undersea telecommunications network could one day help in studying offshore earthquakes.

  • Weather Is Turning into Big Business. And That Could Be Trouble for the Public.

    This may well be the future of weather forecasting: “Now for your local weather forecast: That’ll be $10, please.” Climate change is inflicting an increasingly heavier costs on the U.S. economy, and those rising costs — along with advances in data-gathering and processing, and cheaper access to low Earth orbit — have spurred start-ups and established companies to get into the business of weather forecasting.

  • Technologies to Manage Climate Change Already Exist – but U.K. Needs to Scale Up Efforts Urgently

    In the U.K., climate change is being tackled by taking baby steps. Andreas Busch writes that this is unfortunate, because “The world already has effective engineering solutions to manage climate change and to limit global temperatures from rising above 1.5°C – a target set by the Intergovernmental Panel on Climate Change (IPCC). But there is a desperate lack of conviction from politicians and society to address the climate emergency.”

  • The Sea Wanted to Take This California Lighthouse. Now, It’s Part of a Conflict Between a Town and Two Tribes

    For decades, the Trinidad Memorial Lighthouse stood like atop the coastal bluff overlooking the rocky outcrops of Trinidad Bay in northern California. But then, climate change began to take its toll: “the ground began to crumble. Rain moved the earth. The bluff cracked, a sidewalk warped, and thus ended the charmed life of the Trinidad Memorial Lighthouse, which suddenly threatened to slide into the Pacific,” Hailey Branson-Potts writes.

  • Safeguarding Drones, Robotic Cars against Cyberattacks

    Robotic vehicles like Amazon delivery drones or Mars rovers can be hacked more easily than people may think, new research finds. Researchers designed three types of stealth attack on robotic vehicles that caused the machines to crash, miss their targets or complete their missions much later than scheduled.
