Original: How climate change is altering petrichor, the glorious smell after it rains
The distinctive earthy scent after rainfall, known as petrichor, is changing as the climate warms. Reporting explains that shifts in temperature, rainfall patterns, and soil conditions affect the compounds and microbes that produce the smell, meaning the familiar post-rain aroma may become less common or different in character in many regions.
Why now: It connects a widely loved sensory experience to the tangible, everyday effects of climate change.
