NASA | Human Fingerprint on Global Air Quality

The video discusses nitrogen dioxide emissions from fossil fuels and their impact on air quality. NASA's Aura satellite has been monitoring these emissions since 2004, revealing trends in various regions. In Western Europe, emissions have decreased due to stricter regulations, while in China, they have increased due to coal use, except in cities like Beijing. The Middle East shows a decrease in Syria due to civil unrest, but an increase in neighboring countries. In the US, increases are seen in areas with intensive oil and gas extraction. Monitoring these levels helps understand the effects of energy use, policy, and unrest on air quality.

What factors have contributed to the increase in nitrogen dioxide levels in China?

How has the civil war in Syria affected nitrogen dioxide levels in the region?
