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 »

Toronto WeatherWise Partnership Looks at Adaptation

An increase in extreme weather events and a need for climate change adaptation spurred the foundation of the Toronto WeatherWise Partnership in 2011.  It involves representatives from more than 50 public private and non-profit organizations from across Toronto, including Travis Allan, aiming to identify key risks associated with weather events and develop a strategic action plan to reduce these risks, ...
