A climate tipping point was crossed when ancient tropical forests vanished 252 million years ago—triggering unstoppable warming that trapped Earth in a 5-million-year super-greenhouse. Vegetation loss can push the planet past the point of no return.

A study of 1,100 Bavarians found when considering energy-adjusted diets, higher emissions are associated with being female, having a higher waist circumference, and following an omnivorous diet. Increased consumption of animal products, coffee, and tea contributed to greater environmental impacts.

U.S. preschoolers exposed to potentially harmful chemicals. Urine samples from 201 children found 96 chemicals in at least 5, 48 chemicals in over half and 34 chemicals in more than 90%. Many of these chemicals are known or suspected to interfere with hormones, brain development and immune function.

Inflammation, considered a hallmark of aging, may not be a universal human experience, but may be a byproduct of industrialised lifestyles. A new study did not detect increased inflammation with age in Indigenous, non-industrialised populations and chronic age-related diseases were also minimal.
