Air pollution causes roughly seven million premature deaths each year. Fine particulate matter exceeds safe levels for over ninety percent of the global population. This risk extends from urban traffic to household cooking fuels, tracing a detailed map of human exposure.
Key Takeaways
- PM2.5 concentrations exceed WHO guidelines in 92% of global population
- Air pollution causes 7 million premature deaths annually worldwide
- Nitrogen dioxide (NO2) levels in urban areas are 2-3 times safe limits in many cities
- Global species extinction rate 1,000 times higher than background
- 1 million animal/plant species threatened with extinction
- 75% of terrestrial environments heavily altered by humans
- Global average surface temperature has increased by about 1.1°C since the late 19th century
- Arctic sea ice extent has declined by about 13% per decade since 1979
- Global sea levels have risen by 21-24 cm since 1880, with the rate accelerating to 3.7 mm per year recently
- Global solar PV capacity reached 1,053 GW in 2022
- Wind power generated 2,001 TWh globally in 2022, up 9%
- Hydropower supplied 15.5% of global electricity in 2022
- Global e-waste reached 62 million tonnes in 2022
