Greenhouse gases (GHGs) warm the surface and the atmosphere with significant implications for rainfall, retreat of glaciers and sea ice, sea level, among other factors. About 30 years ago, it was recognized that the increase in tropospheric ozone from air pollution (NOx, CO and others) is an important greenhouse forcing term.
TWO months away from the year-end UN climate summit in the Mexican resort town of Cancun, countries appear to have given up the idea of a binding climate treaty this year. The focus now is on narrowing down differences and providing the framework for an agreement, perhaps in South Africa next year.

Cities represent a challenge and an opportunity for climate change policy. As the hubs of economic activity, cities generate the bulk of GHG emissions and are thus important to mitigation strategies. Urban planning will shape future trends and the concentration of population, socio-economic activity, poverty
This report analyses impacts of four extreme weather events (a heat wave in Russia, flooding in Pakistan, drought in East Africa, and a typhoon in the Philippines) on food security. For each case, the
