• Even low levels of air pollution may quietly scar your heart, MRI study finds
  Breathing polluted air—even at levels considered “safe”—may quietly damage your heart. A new study using advanced MRI scans found that people exposed to more air pollution showed early signs of scarring in their heart muscle, which can lead to heart failure over time. This damage showed up in both healthy individuals and people with heart […]
• Rainforest deaths are surging and scientists just found the shocking cause
  Tropical trees are dying faster than ever, and it's not just heat or drought to blame. Scientists have uncovered a surprising culprit: ordinary thunderstorms. These quick, fierce storms, powered by climate change, are toppling trees with intense winds and lightning, sometimes causing more damage than drought itself. The discovery is reshaping how we understand rainforest […]
• When rainforests died, the planet caught fire: New clues from Earth’s greatest extinction
  When Siberian volcanoes kicked off the Great Dying, the real climate villain turned out to be the rainforests themselves: once they collapsed, Earth’s biggest carbon sponge vanished, CO₂ rocketed, and a five-million-year heatwave followed. Fossils from China and clever climate models now link that botanical wipe-out to runaway warming, hinting that losing today’s tropical forests […]
