Air Pollution and Climate: Towards an Integrated Approach

Air quality and climate change are two very closely linked environmental problems. Many air pollutants that are toxic for human health are also greenhouse gases (GHGs) or GHG precursors. Additionally, the warming climate may increase chemical reaction rates, making smog in cities worse. The International Global Atmospheric Chemistry (IGAC) Project working under the umbrella of the International Geosphere-Biosphere Programme (IGBP), ... Read More »
