Rivers in Peril: Global Migratory Fish Declines Threaten Food and Culture

A global assessment finds migratory freshwater fish collapsing due to dams, overfishing, habitat loss and pollution; 97% of migratory species are at risk of extinction, mega-fish in the Mekong have declined ~95% since 1970, and cross-border cooperation under the Convention on Migratory Species is needed to restore river connectivity and protect livelihoods and diets across major basins.

Hot Cups Leach Microplastics: Temperature Key in Takeaway Coffee

A new study shows takeaway cups shed thousands of microplastic particles when hot, with temperature being the main driver. In Brisbane tests, all-plastic cups released more microplastics than paper cups with plastic linings at both cold and hot temperatures, and hotter liquids increased releases by about one third for plastic cups. The researchers estimate that sipping 300 ml daily from polyethylene cups could expose a person to roughly 363,000 microplastics per year. To reduce risk, use reusable cups or request cooler drinks, and avoid pouring boiling liquids into plastic-lined containers. While health impacts remain uncertain, the study highlights how material choice and heat affect microplastic exposure.

"Mitigating Wildfire Risk: Addressing Climate Change, Aging Power Lines, and Emergency Alert Systems"

Aging power infrastructure and the impacts of climate change are increasing the risk of utilities starting wildfires, as seen in the case of the Smokehouse Creek Fire in Texas. Many utilities lack the technology to detect overheating power lines, and climate change is exacerbating the risk with drier vegetation and hotter weather. While some utilities are investing in solutions like weather sensors and proactive shutoffs, others are not prioritizing wildfire prevention, which could impact both safety and the affordability of electric bills.
