Wildfire Activity in Siberia Has Doubled Driven by Climate Change and Feedback Loops

Wildfire Activity in Siberia Has Doubled Driven by Climate Change and Feedback Loops

Breaking News, Disasters
Wildfire activity in central Siberia has doubled over the past two decades, with vast areas of forest scorched and massive amounts of carbon released from rich soils and permafrost. While Arctic warming is known to exacerbate wildfires, the specific factors driving these events have been difficult to pinpoint, complicating future predictions. New research by Huang et al. sheds light on the key mechanisms behind this surge in wildfire activity. The team found that the increase in Siberian fires is strongly linked to drought, drying soils, and decreased rainfall all symptoms of Arctic climate change. More worryingly, they identified a feedback loop in which wildfires further suppress precipitation, worsening drought conditions and making the region even more fire-prone. How Wildfires S...

Researchers Develop Advanced Imaging Method to Probe Volcanoes

Breaking News, Disasters
A team of researchers from the CNRS and the Paris Institute of Planetary Physics has developed an innovative method for creating high-resolution, deep imaging of volcanoes' internal structures. This breakthrough technique leverages a network of geophones devices that detect seismic waves to capture not only the strong movements caused by earthquakes but also the subtle seismic noise from wind, ocean waves, and human activities. The researchers applied this method to La Soufrière volcano in Guadeloupe, providing an unprecedented 3D view of the volcano’s internal structure to a depth of 10 kilometers with a resolution of around 100 meters. This new imaging technique confirmed the existence of a large magma storage zone, organized as a network of interconnected magma pockets beneath the vo...
Study Finds Droughts Could Last 10 Days Longer by Century’s End

Study Finds Droughts Could Last 10 Days Longer by Century’s End

Breaking News, Disasters
A new study published in Nature reveals that the average duration of the longest annual drought periods could be 10 days longer by the end of this century than previously predicted. This new estimate, based on improved climate modeling techniques, indicates that the risks posed by droughts to societies and ecosystems may be more severe than previously thought. Researchers led by Irina Petrova and Diego Miralles examined drought projections from multiple climate models under moderate and high-emissions scenarios (IPCC's SSP2-4.5 and SSP5-8.5). They calibrated these projections using historical data from 1998 to 2018, focusing on the longest annual dry spells the number of consecutive dry days each year. Key Findings The study suggests that drought periods could extend by 42–44% on ...
Study Reveals U.S. Cities Successfully Limit Floodplain Development Using Existing Tools

Study Reveals U.S. Cities Successfully Limit Floodplain Development Using Existing Tools

Breaking News, Disasters
Contrary to common belief, most U.S. cities are effectively managing floodplain development, preventing costly disasters by utilizing established ordinances, plans, and programs rather than relying on novel strategies. This is the central finding of a new study titled "How local governments avoid floodplain development through consistent implementation of routine municipal ordinances, plans, and programs," published in Oxford Open Climate Change. Despite significant investments in flood mitigation, the cost of disasters in the United States has continued to rise, with floods being the most frequent and expensive disaster. The main driver behind these increasing costs is not just climate change, but also the growing concentration of people and infrastructure in flood-prone areas. A no...

Study Finds Children Born in 2020 to Face Twice as Many Wildfires as Those Born in 1960

Study Finds Children Born in 2020 to Face Twice as Many Wildfires as Those Born in 1960

Breaking News, Disasters, Environment
Children born in 2020 are projected to experience double the number of wildfires over their lifetimes compared to those born in 1960, according to recent studies. In regions like California, wildfires have become a common occurrence during the summer and fall seasons, releasing harmful particulate matter (PM₂.₅) into the air that poses significant health risks. Wildfire-produced PM₂.₅ can penetrate deep into the lungs, causing immediate respiratory issues. While short-term exposure is linked to acute health problems like asthma, the long-term effects of repeated exposure are still unclear. A major challenge is accurately measuring wildfire-related PM₂.₅ exposure, as the intensity of pollution can vary drastically from day to day. Current methods of measuring annual average PM₂.₅, whi...
ASRA Report Calls for Urgent Shift to Systemic Risk Management Amid Rising Global Instability

ASRA Report Calls for Urgent Shift to Systemic Risk Management Amid Rising Global Instability

Breaking News, Climate Actions, Disasters
A groundbreaking report from the Accelerator for Systemic Risk Assessment (ASRA) calls for a radical shift in how governments, businesses, and communities assess and manage global risks. The report, titled Facing Global Risks with Honest Hope, highlights the growing interconnected threats facing the world, from climate change and biodiversity loss to geopolitical conflicts and the unchecked rise of artificial intelligence. Developed by over 50 experts, the report argues that the current approach to risk assessment is outdated and fragmented, leaving decision-makers ill-prepared for today's "polycrisis" moment. Instead of addressing risks in isolation, the authors emphasize the need for a systemic approach that integrates cross-sector collaboration and global governance reforms. One o...
