• Coastal Populations Set to Age Sharply in the Face of Climate Migration

    By Mark Blackwell Thomas

    As climate change fuels sea level rise, younger people will migrate inland, leaving aging coastal populations — and a host of consequences — in their wake. While destination cities will work to sustainably accommodate swelling populations, aging coastal communities will confront stark new challenges.

  • Extreme Weather Cost $80 Billion in 2023. The True Price Is Far Higher.

    By Jake Bittle

    The U.S. saw 25 billion-dollar weather disasters in 2023 — more than ever before. 2024 could be worse. Congress has long punted on reforming FEMA and the nation’s disaster relief policy, but it’s only a matter of time before there’s a disaster bad enough that legislators feel pressure to act. That catastrophe didn’t arrive in in 2023, but it is surely coming.

  • Identifying Types of Cyberattacks That Manipulate Behavior of AI Systems

    AI systems can malfunction when exposed to untrustworthy data – what is called “adversarial machine learning” — and attackers are exploiting this issue. New guidance documents the types of these attacks, along with mitigation approaches. No foolproof method exists as yet for protecting AI from misdirection, and AI developers and users should be wary of any who claim otherwise.

  • Australia Should Learn from Canada and Take a Truly Global Approach to Critical Minerals

    By Ian Satchwell

    Canada and Australia are key players in the global supply chain for critical minerals. Simultaneously the top two nations for receiving minerals investment and for providing minerals investment, they are perfectly placed to use critical minerals to facilitate the global energy transition, foster innovation and build their security capabilities.

  • From NYC to D.C. and Beyond, Cities on the East Coast Are Sinking

    Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year – a decline at the ocean’s edge that well outpaces global sea level rise. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid “subsidence,” or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines.

  • In Coastal Communities, Sea Level Rise May Leave Some Isolated

    By Tatyana Woodall

    Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.

  • Enhancing Coastal Cities' Flood Resilience Through Smart City Technologies

    In the face of climate change, a suite of advanced technologies can be integrated into urban design to reduce the flood risk posed by rising sea levels, more intense rainfall events, and more powerful storm surges.

  • New Nuclear Deflection Simulations Advance Planetary Defense Against Asteroid Threats

    As part of an effort to test different technologies to protect Earth from asteroids, a kinetic impactor was deliberately crashed into an asteroid to alter its trajectory. However, with limitations in the mass that can be lifted to space, scientists continue to explore nuclear deflection as a viable alternative to kinetic impact missions. Nuclear devices have the highest ratio of energy density per unit of mass of any human technology, making them an invaluable tool in mitigating asteroid threats.

  • Smart Microgrids Can Restore Power More Efficiently and Reliably in an Outage

    By Emily Cerf

    It’s a story that’s become all too familiar — high winds knock out a power line, and a community can go without power for hours to days, an inconvenience at best and a dangerous situation at worst. Engineers developed an AI model that optimizes the use of renewables and other energy sources to restore power when a main utility fails.

  • New Insights on Community Resilience and Adaptation

    A major weather event such as a hurricane or wildfire can have lasting, visible impacts on communities, but the longer-term, compounding effects of a changing climate can be harder to see. There are  ways that communities can adapt and become more resilient as the climate changes.

  • Strengthening Domestic Supply Chains for Critical Minerals

    The USGS is investing millions of dollars in strengthening domestic supply chains for mineral resources critical to every economic sector and every member of society. Central to this effort is a nationwide mapping effort for critical minerals.

  • How a Small Caribbean Island Is Trying to Become Hurricane-Proof

    By Emily Wilkinson

    Climate change is increasing the frequency and intensity of extreme weather events in the Caribbean and for small islands such as Dominica (not to be confused with the much larger Dominican Republic) it is an existential threat. Unlike larger islands like Cuba or Jamaica, a single storm hitting Dominica can damage the entire country – and the topography and small size of the island imposes hard limits on its ability to adapt.

  • We Rarely Hear About the Disasters Which Were Avoided – but There’s a Lot We Can Learn from Them

    By Ilan Kelman, Ana Prados, Brady Podloski, and Gareth Byatt

    We frequently see headlines about disasters. But where are the headlines covering the good news of lives saved and damage averted when disasters do not happen? Our work, now published, offers examples we can learn from.

  • Learning from When the Earth Moves: Protecting Indonesia’s New Capital City

    By Louise Walsh

    Indonesia plans to build a new capital city from scratch. Protecting the new city from the effects of earthquakes will be crucial. Here’s how researchers are helping.

  • Reducing Flooding Impacts in Coastal Towns

    Researchers study the benefits and costs of flood-reduction strategies aimed at increasing coastal resilience to storms and sea-level rise. The researchers will apply advanced computer models to simulate how these strategies affect water levels both on the surface and underground and the flooding of homes, businesses and infrastructure.
