A European Commission JRC forecast warns that late July to early August could bring the worst fire danger yet across western and central Europe, with extreme conditions driving the risk; wildfire smoke is already harming air quality and health, while UK and Spain tie the fires to climate change and urge stronger action.
The Conversation study reframes the famous 1976 UK heatwave for today’s climate, showing that if the event occurred now, peak temperatures would reach about 38–39°C and 15 days would exceed 35°C, due to a warmer global baseline and intensifying extremes. The result would exacerbate health risks, disrupt transport and infrastructure, and demand urgent emissions cuts and adaptation as summers grow hotter.
The 2026 State of the Air report shows Los Angeles-Long Beach as the nation’s worst metro for ozone, with 82% of Californians living in counties with unhealthy air and 44% of Americans in areas failing at least one pollution standard. The findings emphasize transportation and industry as primary sources and warn that federal rollbacks could weaken California’s clean-air authority, potentially causing more than 14,000 deaths and $145 billion in health costs through 2050. While some California areas posted improvements—Sacramento’s lower particle pollution and several cities with zero high-ozone or zero unhealthy PM2.5 days—advocates urge continued funding for zero-emission trucks and other controls to protect public health, especially children.
Air strikes on Tehran's oil facilities have produced dense smoke plumes and an unprecedented mix of pollutants, with reports of 'black rain' as fires burn at the Tehran refinery and Shahran depot; the WHO warns such attacks risk harming air, water and food, and scientists say the pollutant mix is unusually dangerous, potentially causing immediate and long-term health risks even as forecasts of rain and wind may help disperse contaminants.
Neanderthal DNA, inherited through ancient interbreeding with modern humans, influences various aspects of our health and physical traits today, including skin color, immune response, and susceptibility to certain diseases, while also offering insights into human evolution.
The report updates on plastic pollution, highlighting that without urgent global action, plastic entering the environment will nearly double by 2040, causing severe health, environmental, and climate impacts. It emphasizes the need for transformative policies to reduce plastic production, improve waste management, and shift towards a circular economy to mitigate these risks and create economic opportunities.
Clocks fall back this Sunday, but Congress remains divided over whether to end seasonal time changes, with ongoing debates about health, safety, and convenience, and some states pushing for permanent standard or daylight saving time.
Changing clocks for daylight saving time can negatively affect health, increasing risks of heart attacks, strokes, mood disorders, and traffic accidents, especially when clocks are moved forward in spring, due to disruption of circadian rhythms and sleep patterns. The autumn shift appears less harmful, but still has some risks. Overall, the health benefits of DST are questionable, and some experts suggest eliminating it altogether.
A recent study has found microplastics deep inside human bones, including bone marrow, and suggests they may harm health by impairing cell viability, accelerating aging, and potentially contributing to bone diseases like osteoporosis, prompting further research into their impact on bone health and fractures.
New research suggests that daylight saving time may negatively affect long-term health by disrupting circadian rhythms, potentially increasing the risk of obesity and stroke, and that adopting permanent standard time could reduce these health issues.
The 2023 Canadian wildfires burned a record amount of forest, significantly increasing PM2.5 pollution globally, affecting air quality and causing an estimated 5,400 acute and 82,100 chronic deaths worldwide, with impacts reaching North America, Europe, and beyond, highlighting the extensive health and environmental consequences of large-scale wildfires.
Over the past 80 years, more than 2,000 nuclear tests have left lasting health and environmental impacts on communities worldwide, especially those downwind of testing sites, with increased cancer risks and ongoing contamination issues, highlighting the long-term consequences of nuclear proliferation and testing.
Recent studies reveal that the health toll of the Maui and LA wildfires extends beyond immediate fatalities, with significant increases in lung damage, mental health issues, and indirect deaths such as suicides and overdoses, highlighting the extensive and lasting human health impacts of these climate-driven disasters.
A report in The Lancet warns that plastic pollution causes significant health issues across all ages, costing at least $1.5 trillion annually, and calls for an international treaty to address the crisis, highlighting the link between plastic and climate change.
Wildfire smoke, containing toxic gases, particulate matter, and potentially microbial pathogens, poses serious health risks beyond respiratory issues, including cardiovascular, neurological, and mental health effects, with research emphasizing the need for protective measures and further study.
