How 'super pollutants' are harming human health and worsening climate change

While the fight against climate change has primarily focused on carbon dioxide (CO2), a group of other greenhouse gases and aerosols – known as “super pollutants” – have a significant impact on global temperatures and human health. They are responsible for about 45 % of global warming to date, as well as millions of premature deaths each year.

Reducing emissions of these non-CO2 substances, including methane, hydrofluorocarbons and black carbon, is considered one of the fastest ways to address climate change.

Studies have shown how global measures to reduce emissions of super-pollutants could prevent four times more warming by 2050 than decarbonization policies alone.

At the same time, it could prevent around 2.4 million deaths annually caused by air pollution. (Dr. Rachel Huxley, Dr. Drew Shindell, Talia Caplan, more at carbonbrief.com)
