• GeoengineeringArctic “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.

  • Climate crisisEarly 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.

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

    By Emily Fusco

    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.

  • FloodsBolstering 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.

  • Climate crisisThe 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.

  • WildfiresCalifornians Unwilling to Subsidize Wildfire Prevention: Poll

    With blazes raging across the state, smoke impacting the Bay Area and the largest power utility shutting off electricity to avoid ignitions, California is experiencing another devastating fire season. As state, federal and local officials try to figure out what policies to implement to address the state’s wildfire crisis, a new poll reveals where the public stands on regulations and other public policy measures to prevent wildfires.

  • Power gridGrid 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.

  • EarthquakesUnderwater 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.

  • Perspective: Weather businessWeather 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.

  • Perspective: Climate threatsTechnologies 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.”

  • Perspective: Coastal challengesThe 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.

  • EarthquakesQuake Kills at Least 27 in Albania, State of Emergency Declared

    The death toll from the strongest earthquake to hit Albania in more than three decades rose to at least 27 on Wednesday, as the country observed a day of mourning. The U.S. Geological Survey said the quake was a magnitude 6.4 with an epicenter 30 kilometers northwest of the capital, Tirana. Three hours after the initial quake, a magnitude-5 aftershock struck in the Adriatic Sea.

  • Thoughts and prayersPrayers May Crowd Out Donations for Disaster Victims

    People who offer prayers for victims of natural disasters may be less likely to donate to those victims, according to research. “The results suggest that the act of praying is a substitute for material help — in other words, prayers crowd out donations, at least in some contexts,” Professor Linda Thunstrom says.

    A new modeling approach can help researchers, policymakers and the public better understand how policy decisions will influence human migration as sea levels rise around the globe. “Sea level rise is going to reorganize the human population around the globe,” says one researcher.
