Smoke from Wildland Urban Fires Poses Greater Health Risk Than Remote Wildfires

Breaking News, Climate Actions, Environment

Smoke from fires that rage through wildland-urban interface (WUI) areas where human development meets wildland vegetation has a significantly higher health impact than smoke from wildfires in remote areas, according to a groundbreaking study published in Science Advances. The research, led by scientists at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), reveals that emissions from WUI fires are about three times more likely to contribute to premature deaths annually than emissions from wildfires in general. The reason: WUI fires burn closer to populated areas, exposing more people to harmful pollutants like fine particulate matter and ground-level ozone. Rising Risk of WUI Fires The wildland-urban interface has been expanding globally, now...

Climate Change Pushing Amphibians Beyond their Tolerance Heatwave Study Warns

Breaking News, Climate Actions, Environment

A new study published in Nature has revealed that two per cent of the world’s amphibians are already experiencing temperatures beyond their tolerance limits raising alarms about the impact of global warming on these highly vulnerable species. Researchers studied 5,203 amphibian species and found that 104 are already exposed to overheating in shaded terrestrial conditions. The study warns that if global temperatures rise by 4°C, as many as 7.5 per cent (391 species) could be pushed beyond their physiological limits, significantly increasing the risk of extinction. Amphibians are ectothermic meaning they regulate body heat using external sources. As over 40 per cent of amphibian species are already under threat rising thermal extremes could accelerate their decline. Scientists analyzed...

New Climate Risk Index Reveals Global Inequities in Climate Crisis

Breaking News, Climate Actions, Environment

A newly released Climate Risk Index (CRI) highlights the devastating impact of extreme weather events worldwide, underscoring the urgent need for stronger climate adaptation and risk management policies. Unlike the Climate Change Performance Index (CCPI), which evaluates countries' mitigation efforts, the CRI ranks 171 nations based on the human and economic toll of climate-related disasters. The 2025 report, published by Germanwatch confirms that lower-income nations bear the brunt of climate change, despite contributing the least to global emissions. Over a 30-year analysis (1993-2022), five of the ten most affected nations were lower-middle-income countries including India, Myanmar, and the Philippines while high-income nations like Italy and Spain also made the list. The year 2022 a...

Climate Change Alters Rainfall and Flood Patterns Differently Over Time Scales

Breaking News, Climate Actions, Environment

A new study has revealed that climate change influences short-term and long-term rainfall and flooding in different ways, shedding light on how rising temperatures impact local and regional water systems. Researchers from Austria have provided the first comprehensive analysis of this relationship, using over a century of high-quality weather data. Their findings, now published in Nature, have global implications for understanding how floods may intensify in different regions. The study, led by Prof. Günter Blöschl of TU Wien (Vienna), shows that short-duration rainfall events lasting just a few hours have increased by 15% in the last 30-40 years. The main driver behind this increase is rising temperatures caused by climate change. Warmer air holds more moisture, while increased groun...

Rising Groundwater Threatens Inland Flooding in Coastal Cities

Breaking News, Climate Actions, Environment

Rising sea levels caused by climate change are bringing an often-overlooked threat to coastal communities rising groundwater. While coastal erosion and storm surges have been widely studied, the inland spread of flood hazards due to groundwater rise remains a hidden danger. A recent study by Cox et al. focuses on Dunedin, New Zealand, a city already facing periodic flooding, and presents a method to predict how rising seas will impact groundwater levels, offering crucial insights for flood risk management. The research, based on data from 2019 to 2023 collected from 35 groundwater sensors, shows that as sea levels rise, groundwater levels will also increase, limiting the land’s ability to absorb rainfall and leading to higher risks of surface flooding. Even before reaching the surfac...

Rising seas groundwater loss and urban expansion push Asia megadeltas toward crisis

Breaking News, Climate Actions, Environment

Coastal flooding in Asia’s megadeltas is intensifying due to rapid urbanization, land use changes, excessive groundwater extraction, infrastructure development, and widespread sand mining. Since 1990, urban areas below five meters above sea level have expanded by over 70% in the Ganges-Brahmaputra-Meghna and Mekong deltas, and by at least 200% in the Chao Phraya delta. The excessive withdrawal of groundwater has accelerated land subsidence in all five megadeltas, with sinking rates surpassing one centimeter per year. Additionally, intense river sand mining, driven by the high demand for construction materials, has contributed to severe erosion along riverbanks and coastlines. Dams built upstream further disrupt natural river flows by trapping sediments that are essential for maintain...
