Rising Temperatures Rising Heart Risks: How Extreme Heat Strains the Heart

Breaking News, Climate Actions, Fact Check

For years scientists have studied how heat affects the human heart. However new research suggests that the most commonly used testing methods may not accurately reflect what happens during real-world heat waves. As climate change drives global temperatures higher understanding the true impact of extreme heat on heart function has become more crucial than ever. A groundbreaking study has uncovered key insights into how the human heart responds to heat stress. This findings could reshape how health agencies protect vulnerable populations during extreme weather events. The study analyzed data from over 400 laboratory studies involving more than 6,800 participants, revealing significant differences in how heating methods influence heart performance. Researchers find that exposure to enca...

India Air Pollution Crisis Damaging Despite Slight Improvement

Breaking News, Climate Actions, Environment, Fact Check

Despite a 7% drop in PM2.5 levels India remains the world's fifth most polluted country, with six of the ten most polluted cities globally. The 2024 IQAir World Air Quality Report reveals that India’s annual PM2.5 average fell to 50.6 µg/m³ from 54.4 µg/m³ in 2023, yet pollution levels remain alarmingly high. New Delhi, a pollution hotspot, recorded an annual PM2.5 average of 91.6 µg/m³, showing little change from the previous year. Northern states continue to suffer from severe pollution spikes, with Baddi in Himachal Pradesh reporting a shocking PM2.5 level of 165 µg/m³ in January. Stubble burning contributed to 60% of PM2.5 levels in Punjab, Haryana, and surrounding regions, worsening air quality in November. Air pollution remains a major public health crisis, reducing life expect...

Climate Change and Sewage Linked Viruses Growing Health Risks

Breaking News, Climate Actions, Environment

Rising temperatures and extreme weather events may be increasing the risk of virus exposure from sewage-contaminated waters, a new study warns. Scientists have found that viruses from raw sewage can persist in rivers, lakes, and seas for days, raising public health concerns. Heavy rainstorms often overload sewer systems, leading to untreated sewage being discharged into natural water bodies. This waste carries viruses such as enterovirus and norovirus, which can remain infectious for days, even after passing through wastewater treatment plants. In seawater, enteric viruses stayed infectious for up to three days at 30°C, while cooler temperatures extended their lifespan to a week. Sunlight reduced their viability to less than 24 hours on sunny days, but they survived for 2.5 days in clou...

Researchers Portable Lab Detect Dangerous Avian Flu in Antarctica

Breaking News, Climate Actions, Environment

Biosecurity efforts in remote regions have taken a major leap forward with the introduction of a portable laboratory capable of on-site testing for Highly Pathogenic Avian Influenza (HPAI) H5N1. Minister for Biosecurity Andrew Hoggard announced the breakthrough following successful trials conducted by Biosecurity New Zealand during an expedition to Antarctica. The portable lab was tested aboard the icebreaker MV Argus, where researchers used it to locate, sample, and analyze potential HPAI H5N1 cases under extreme conditions. The development comes at a critical time, as the virus first detected in 2020 has spread globally and was confirmed on the Antarctic Peninsula in February 2024. Affected species include brown skuas, Adélie penguins, snowy sheathbills, and Antarctic fur seals. "T...

Australians Face Death Risk in Heatwaves: Study Reveals Cities as Hotspots for Extreme Temperature & HVI

Breaking News, Climate Actions, Disasters

A groundbreaking study conducted by researchers from the University of Queensland and Griffith University has revealed that urban residents in Australia face a significantly higher risk of death during heatwaves compared to their rural counterparts. The research, published in the Environmental Impact Assessment Review in March 2025, examined two decades of temperature and mortality data across Australia’s major cities, including Melbourne, Sydney, Adelaide, Brisbane, Hobart, Perth, and Darwin. The study utilized the Heatwave Vulnerability Index (HVI) to identify regions most susceptible to heatwave-related fatalities. Even during mild heatwaves, there was a notable correlation between deaths and HVI scores in Australia’s capital cities. The far north and southern regions of Western Aust...

Guillain-Barre Syndrome Claims Two Lives in Andhra Pradesh, Sparks Health Alert

Breaking News, Disasters, Environment

In Andhra Pradesh, health authorities have sounded the alarm after two deaths from Guillain-Barre Syndrome (GBS) were reported. Dr. Sivananda, Superintendent of King George Hospital in Visakhapatnam, described GBS as a rare, non-contagious post-viral condition that can cause paralysis and autoimmune disorders. He noted that GBS affects only two out of every two lakh people. Health Minister Satya Kumar Yadav confirmed the deaths occurred in Guntur and Srikakulam districts. While acknowledging the syndrome’s 5-7% global mortality rate, Yadav reassured the public that Chief Minister Chandrababu Naidu has directed comprehensive response measures. He urged people to remain calm and seek immediate medical attention if symptoms appear. The state’s first GBS-related death was recorded at Gun...

B.C. Health Workers Face Mounting Climate Crisis Strain

Breaking News, Climate Actions

British Columbia has faced a series of climate-related extreme weather events in recent years, with severe consequences for both residents and health services. The 2021 heat dome led to over 600 heat-related deaths and overwhelmed emergency services, while wildfires caused increased illnesses and forced the evacuation of thousands. B.C.’s health system, already strained by staffing shortages and burnout from the COVID-19 pandemic, has worked to respond to these emergencies. However, many health service workers reported physical and mental health challenges during and after climate events. Front-line staff, such as paramedics and home health workers, faced exposure to heat and poor air quality, especially when facilities lacked proper cooling and air filtration systems. The mental tol...
