Aerosolit 10
Sarja 3 www.climatefresk.org 10 Ei mitään tekemistä aerosol - pullojen kanssa. Aerosolit ovat paikallista hiukkassaasteita, jotka johtuvat fossiilisten polttoaineiden epätäydellisestä palamisesta. Ne ovat haitallisia ihmisten terveydelle ja vaikuttavat negatiivisesti säteilypakotteeseen, mikä taas tarkoittaa, että niillä on ilmastoa viilentävä vaikutus.

Aerosols

Although aerosols are not alone in the "fine particle" category, every year 391,000 people in EU countries die from air pollution, and it causes 1.1 million premature deaths in India and China. Air pollution such as soot caused by the burning of fossil fuels such as coal and oil was responsible for 8.7m deaths globally in 2018.

Other possible causes

Building Usage

Building Usage

Buildings emit few aerosols directly. The only significant emissions are chimney fires. In Chamonix, 85% of the fine particles present in the atmosphere come from wood heating.
Transportation

Transportation

Local pollution due to exhausts pipes is one of the main motivations to promote electric cars, far more than climate change. But EV are responsible for CO2 emissions due to power generation. These emissions depend a lot on the country where the car is rolling. See the file about it.
Agriculture

Agriculture

Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants.
Forest Fires

Forest Fires

Smoke from wildfires has been shown to carry toxic particles.
