Скачать или смотреть Global Aviation Impact on Climate System Change is HUGE

On June 29th, 2019 a record 202,157 planes flew; essentially double the quietest day (Christmas Day, 2018) in the past 12 months. Peak number of simultaneous flights on June 29th was above 19,000. Each year, there are 4 billion passengers, expected to double over the next two decades. About 4 to 9% of the climate change impact of human activities is from aviation. Since 1990, carbon dioxide emissions from flying are up 83%; the climate impact is 2-4x that of the carbon dioxide alone. The “cheap fares” are NOT cheap in terms of their huge climate change impacts.
