• Onset of Modern Sea-Level Rise Began in 1863, International Study Finds

    Researchers have found that modern rates of sea-level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt.

  • Tornadoes, Climate Change Make Dixie the new Tornado Alley

    Studies do show tornadoes getting more frequent, more intense and more likely to come in swarms. Moreover, studies show that, statistically, there is an emergence of another center of tornado activity in the Southeast, centered around Alabama. Oklahoma still has tornadoes, of course. But the statistical center of Tornado Alley has moved eastward.

  • Ultrafast Devices to Protecting the Grid from EMPs

    Scientists from Sandia National Laboratories have announced a tiny, electronic device that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts — a significant step towards protecting the nation’s electric grid from an electromagnetic pulse.

  • Un-Earthing Planetary Defense

    This summer, NASA will launch its first mission to a metallic asteroid, 16 Psyche, located in the main asteroid belt between the orbits of Mars and Jupiter. Previous missions have explored rocky and icy asteroids, but Psyche’s composition is widely believed to consist of a considerable amount of metal. Studying extraterrestrial bodies could help defend Earth from future impact threats.

  • Wildfires Devastate the Land They Burn, and They Are Also Warming the Planet

    The 2021 wildfire season broke records globally, leaving land charred from California to Siberia. The risk of fire is growing, and a recent report warned that wildfires are on track to increase 50% by 2050. These fires destroy homes, plant life, and animals as they burn, but the risk doesn’t stop there. Researchers detail how the brown carbon released by burning biomass in the northern hemisphere is accelerating warming in the Arctic and warn that this could lead to even more wildfires in the future.

  • How a Hurricane Fueled Wildfires in the Florida Panhandle

    The wildfires that broke out in the Florida Panhandle in early March 2022 were the nightmare fire managers had feared since the day Hurricane Michael flattened millions of trees there in 2018. It might sound odd – hurricanes helping to fuel wildfires. But Michael’s 160 mph winds left tangles of dead trees that were ready to burn.

  • Texas Cold Snap Highlights Need for Improved Power Systems

    The greatest demand for electricity in Texas is traditionally during the hottest days of the year, when air conditioners turn on full blast to beat the heat. But in February 2021, an unusually long spell of cold weather took the region by surprise. With extreme weather events rising in frequency, the need for a prepared modern energy grid grows.

  • Hurricanes and Other Tropical Cyclones Linked to Rise in U.S. Deaths from Several Major Causes

    New study reveals potential hidden deadly cost of climate-related disasters: Injuries, infections, diseases, respiratory diseases, cardiovascular diseases, and neuropsychiatric disorders.

  • The Evolution of U.S. Emergency Risk Assessment and Response

    The U.S. emergency management system evolved from responses to many past situations, including the Great Depression and the Cold War. The current system formed as a seeming patchwork of federal, local, nonprofit and other agencies. While the current system has advantages and weaknesses, understanding its makeup can help us address current crises, including pandemics and climate change.

  • As Sea Levels Rise, Coastal Megacities Will Need More Than Flood Barriers

    Sea level rise is expected to worsen in the next few decades, especially for many of the world’s largest cities in lower and middle income countries of Africa, Asia and Latin America. These cities are already improving their infrastructure. But most of the focus remains on big engineering solutions (like flood walls and embankments) rather than a more holistic plans.

  • Social Media May Create Ambiguity during Acute Crises

    In an acute crisis, it can be difficult to know exactly what has happened and how to respond. Sometimes it’s not a lack of information that is the biggest problem, but that huge amounts of information on social media create ambiguity. During such times, it is particularly important to be critical of sources, as both the behavior of users and the structure of the platforms contribute to this lack of clarity.

  • Climate Change Contributor to 2017 Oroville Dam Spillway Incident

    A one-two punch of precipitation resulted in damage to Oroville Dam’s main and emergency spillways pushing the second largest dam in California into a crisis in February 2017. Researchers say that they have identified the fingerprint of climate change in the events that triggered the incident. Issues with the dam’s spillways led to the evacuation of 188,000 people.

  • Last-Minute Defense Against an Asteroid: Obliterating It Before Impact

    Scientists say that pulverizing a threatening incoming asteroid into tiny pieces is our best bet to protect ourselves from an asteroid on short notice.

  • An Asteroid Impact Could Wipe Out an Entire City – NASA’s Plans to Prevent a Potential Catastrophe

    The Earth exists in a dangerous environment. Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet. Most of these are too small to pose a threat, but some can be cause for concern. Are governments spending enough money to prevent an asteroid catastrophe?

  • Number of Wildfires to Rise by 50% by 2100 and Governments Are Not Prepared

    Even the Arctic, previously all but immune, faces rising wildfire risk, experts say. Wildfires and climate change are “mutually exacerbating.” Governments are called to radically shift their investments in wildfires to focus on prevention and preparedness.
