The year 2015 was the warmest on record globally. In Asia, we saw the strongest El Nino ever recorded, which was linked to drought in Southeast Asia, wildfires in Indonesia and an unusually active cyclone season in the Pacific. We also saw the first ever "red alert" for smog in Beijing, driven in part by the burning of fossil fuels, which contribute to climate change.
But we also saw real progress in tackling climate change with the historic agreement in Paris by 196 countries, including China, to try to limit the rise in global temperature to less than 2 degrees C. While talking about the impacts of climate change, however, we often overlook the world's middle-class population, which has swelled to 1 billion and is concentrated in rapidly growing, densely populated cities, mostly located in coastal areas of emerging markets where manufacturing and trade have flourished.
The Paris agreement comes at a critical time for them: UBS's analysis of data for more than 200 cities around the world found that the middle class is highly exposed to weather hazards and underinsured. Our report, "Climate Change: A Risk to the Global Middle Classes", concludes Asia, China in particular, is high on the risk indicators given the rapid urbanization and economic progress of the region.
These risks take several forms. High temperatures harm productivity in both agricultural and non-agricultural industries. When annual average temperatures reach between 20 C and 30 C, labour supply, productivity and crop yields all decline abruptly.
Also, a city can be a dangerous place during heat waves. Large expanses of asphalt and limited green space contribute to a localized increase in temperature of up to 3 C during the day and by as much as 12 C in the evening. This exponentially increases the risk of heat-related mortality－more than 50,000 Russians died in the heat wave of 2010. Air-conditioning helps, but ultimately creates a vicious cycle: increased energy demand leads to increased air pollution from fossil fuels and higher carbon dioxide emissions that drive up temperatures further.
