• Delay and Pay: Tipping Point Costs Quadruple After Waiting

    There’s more to weigh than catastrophic environmental change as tipping points draw near. Another point to consider, a new study reveals, is the cost of undoing the damage.

  • Thinking the Unthinkable at COP29

    We shouldn’t need to be thinking of future global temperatures well in excess of 2 degrees Celsius above pre-industrial levels, where the wildfires, droughts, flooding and other extreme weather effects of climate change are expected to become catastrophic. But alas the consequences of burning all those fossil fuels for energy and the feeble progress towards cutting emissions means that is where we are heading at the moment. Has the time come to consider climate repair as a necessary measure?

  • New AI Tool Generates Realistic Satellite Images of Future Flooding

    Visualizing the potential impacts of a hurricane on people’s homes before it hits can help residents prepare and decide whether to evacuate. The method could help communities better prepare for approaching storms.

  • Collaborative Planning for Australian Food Security Preparedness

    Australia’s food security, commonly assumed safe thanks to our being a net food exporter, is increasingly vulnerable in a world marked by geopolitical and environmental instability.

  • Wargaming the Future of Climate Change

    Military leaders have used games to think through everything from nuclear escalation to pandemic disease to the dangers of artificial intelligence. Players in these games might face any number of calamities with every turn—but, until recently, climate change was not one of them. That has changed.

  • Global Catastrophic Risk Assessment

    Global catastrophic and existential risks hold the potential to threaten human civilization. Addressing these risks is crucial for ensuring humans’ long-term survival and flourishing.

  • Can We Live on Our Planet without Destroying It?

    With eight billion people, we use a lot of the Earth’s resources in ways that are likely unsustainable. How can we adapt our lifestyle to stay within the limits of what the Earth can give? Klaus Hubacek investigates planetary boundaries.

  • Amid Hurricane Milton’s Devastation, a Sliver of Good News

    Earlier this month Hurricane Milton caused an estimated $50 billion in damage and claimed the lives of at least 14 people, yet didn’t deliver the scale of destruction some had feared. Cellphone data suggest evacuation mandates, warning systems worked.

  • Climate-Fueled Extreme Weather Is Hiking Up Car Insurance Rates

    As climate change accelerates, hurricanes, wildfires and hail storms pound the U.S. with growing vigor—and the insurance market is struggling to foot the bill of the damages they leave behind for customers. Home insurers have raised premiums after extreme weather events. Now car insurers in the U.S. are doing the same thing.

  • Hybrid Reef-Mimicking Experiment Could Provide Protection from Storms and Coastal Flooding

    The U.S. Air Force installed a new kind of structure in the waters of St. Andrew Bay on the shore of the Tyndall U.S. Air Force Base in Florida. The first section of the “self-healing” reef is made of custom-designed concrete modules and living oysters. The reef is designed to protect the base and its people from hurricanes and tidal surges.

  • Tracking Flooding in Coastal Communities During Hurricanes Helene and Milton

    A web-based application that gathers crowdsourced data to identify flooding and inform policy in coastal communities provided scientists with essential data from hurricanes Helene and Milton.

  • Recent Hurricanes and Geoengineering

    The recent back-to-back hurricanes that made landfall in the United States have sparked conspiracy theories about the government creating these disasters through geoengineering. While such theories are false, they have drawn attention to the risky idea of geoengineering, which typically refers to the large-scale, intentional manipulation of the earth’s processes to modify weather.

  • Helene and Milton Upended a Key Part of the Nation’s Agriculture System

    America depends on Southeastern agriculture. After two hurricanes and billions of dollars in damages, the US food supply chain faces an uncertain future.

  • When Hurricane Evacuation Isn’t an Option

    Those who remain to face a hurricane are often labeled brave or stubborn. Sometimes they feel the threat is overblown, the need to leave overstated. But some have no other choice. Not everyone rides out storms like Milton or Helene by choice. Some simply cannot afford to flee.

  • What Happened When a Meteorite the size of Four Mount Everests Hit Earth?

    Billions of years ago, long before anything resembling life as we know it existed, meteorites frequently pummeled the planet. One such space rock crashed down about 3.26 billion years ago. The giant impact had silver lining for life, according to new study.
