"Air pollution is often called the 'invisible killer', but these images make the invisible visible," says Dr. Kirsty Pringle, highlighting the stark reality of air quality issues.
The graphs combine data from computer simulations and satellite observations, estimating changing concentrations of particulate pollution since the 1850s, showcasing the persistence of air quality challenges.
Despite significant improvements in some cities since the 1960s, 99% of the world population lives in areas with dangerously dirty air, emphasizing the global urgency of addressing pollution.
The World Health Organisation's guideline for PM2.5 is 5 micrograms per cubic meter, yet there is currently no recognized safe level, underlining the severity of pollution levels worldwide.
