• Earthquake Forecast for Puerto Rico: Dozens More Large Aftershocks Are Likely

    The physics of earthquakes are astoundingly complex, but our abilities to forecast future earthquakes during a strong sequence of events in real time is improving. Forecasting earthquakes is not a strict prediction – it’s more like a weather forecast, in which scientists estimate the likelihood of future earthquake activity based on quakes that have already occurred, using established statistical laws that govern earthquake behavior.

  • The Heat Human Activity Has Added to World’s Oceans in the Past 25 Years Is Equivalent to 3.6 Billion Hiroshima-Size Bombs

    The Hiroshima atom-bomb exploded with an energy of about 63,000,000,000,000 Joules. The amount of heat mankind has put in the world’s oceans in the past 25 years equals to 3.6 billion Hiroshima atom-bomb explosions. A new analysis shows the world’s oceans were the warmest in 2019 than any other time in recorded human history, especially between the surface and a depth of 2,000 meters. The new studyalso concludes that the past ten years have been the warmest on record for global ocean temperatures, with the past five years holding the highest record.

  • 2019: 2nd Wettest Year on Record for U.S.; $14 Billion Climate Disasters

    It was another year of record-making weather and climate for the U.S. in 2019, which was the second wettest behind 1973. Fourteen billion-dollar disasters that struck the U.S. last year included Hurricane Dorian, historic flooding and severe storms.

  • The Lessons from Australia’s Fires

    You might think that Australia is particularly vulnerable to forest fires. But that would be a mistake. Many other countries share the same conditions that have set Australia ablaze, physically and politically, including similar terrain and a leadership that has yet to wake up fully to the new reality that climate change is creating.

  • Ways to Strengthen the Resilience of Supply Chains After Hurricanes

    A new report from the National Academies of Sciences recommends ways to make supply chains — the systems that provide populations with critical goods and services, such as food and water, gasoline, and pharmaceuticals and medical supplies – more resilient in the face of hurricanes and other disasters, drawing upon lessons learned from the 2017 hurricanes Harvey, Irma, and Maria.

  • Climate Change to Make Wildfires in Oregon's Blue Mountains More Frequent, Severe

    Under a warming climate, wildfires in Oregon’s southern Blue Mountains will become more frequent, more extensive and more severe, a new study finds. The researchers urge forest managers to continue to reduce fuel continuity through accelerated rates of thinning and prescribed burning to help reduce the extent and severity of future fires.

  • Extreme Conditions Created “Perfect Storm” for Catastrophic Aussie Fires

    An Australian fire expert says her analyses of bushlands around Sydney in the final months of 2019 indicated that the landscape was primed for these catastrophic fires—but it was series of other conditions, all happening concurrently, that ultimately led to the disaster. The recent drought conditions were key to creating the “perfect storm” that allowed all other pre-conditions to occur concurrently.

  • New Wildfire Reality: Helping Land Managers Take Risk-Analysis Approach

    New digital tools will enable land managers to better adapt to the new reality of large wildfires through analytics that guide planning and suppression across jurisdictional boundaries that fires typically don’t adhere to.

  • Australia’s Fires: The Worst Is Yet to Come

    “Human-caused climate change is most certainly an important contributing factor to the recent fire season in Australia,” says an expert. “What is perhaps most concerning, is that while this year’s fire season, just now underway, appears to be unprecedented, forecasts suggest it will be dwarfed by future conditions.”

  • International Effort to Improve Urban Resilience

    Extreme climate events are severely affecting communities in the U.S. and around the world. The examples are plenty. Bushfires in Australia, wildfires in California, flooding on both U.S. coasts and inland, and much more. In the face of extreme climate events, experts explore developing nature-based solutions.

  • ResponderCQ Measures Disaster Resilience, Response Capabilities

    Disaster response has dominated headlines for years, and technologies to enhance disaster response capabilities are rapidly emerging. Now, a new global dialogue is centering on resilience—how we not only come together to help communities quickly recover, and even thrive, post-disaster, but how we strengthen their defenses against future threats. DHS S&T funded the development of guidance and tools to help communities measure their “Capability Quotient (CQ),” which is the readiness to respond to risk and to respond to disruptions of any kind.

  • Climate Change Intensified Hurricane Florence’s Precipitation and Size

    found that Hurricane Florence produced more extreme rainfall and was spatially larger due to human-induced climate change. Previous research has suggested that human influences such as emission of greenhouse gasses that alter climate does affect precipitation in extreme storms. The research in this study, however, is a first to use a “forecast attribution” framework that enables scientists to investigate the effect of climate change on individual storm events days in advance.

  • Australia: Rising Temperatures, Intensifying Winds Threaten New Fire Wave

    Firefighters in Australia are working around the clock as temperatures and winds are expected to pick up in the coming days, threatening to ignite a fresh wave of fires. Prime Minister Scott Morrison will meet with leaders of financial institutions and agencies to discuss the soaring costs of the on-going crisis.

  • Climate Changes Detected in Daily Weather

    Climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate –but climate change can now be detected in daily weather.

  • 6. Climate Change’s Threat to National Security

    The past year saw more military and intelligence services of more governments give expression to their recognition of the serious threat the consequences of climate change pose to national security and international stability.
