How to live with climate change 如何与气候变化共处[2010.11.25] The Economist Even if the currently moderate pace of emissions reduction steps up, the likelihood is that the Earth will be at least 3°C warmer at the end of this century than it was at the start of the industrial revolution; less warming is possible, but so is more, and quicker. The best protection against global warming is global prosperity. Wealthier, healthier people are better able to deal with higher food prices, or invest in new farming techniques, or move to another city or country, than poor ones are. Richer economies rely less on agriculture, which is vulnerable to climatic change, and more on industry and services, which by and large are not. Richer people tend to work in air-conditioned buildings. Poor ones tend not to. Beyond encouraging climate-friendly development, governments need to take some focused measures in three areas: infrastructure, migration and food. The Dutch, who have centuries of experience of protecting themselves against high water, are already working out how to adapt and build infrastructure to minimise the risks of flooding as sea levels rise and the rain-fed Rhine grows friskier. Elsewhere, politicians need to assess the vulnerability of their cities to changes in peak temperatures, in rainfall, in severe-storm frequency and in sea level, and act accordingly.As life gets harder in vulnerable places, people will need to migrate both between and within countries. Rich people can help make life easier for poor ones by allowing larger numbers across their borders. Within rich countries, governments should stop subsidising insurance in vulnerable areas—such as the Florida coastline—and thus stimulating development there. People need to be encouraged to migrate away from vulnerable areas, not into them. Food security will become a crucial issue. Drought-resistant seeds are needed; and, given that the farmers least able to pay will require the hardiest varieties, seed com
