問題詳情
四、閱讀測驗 Global warming is expected to affect agriculture in every part of the world but it will have greater impact in thetropics and subtropics, where crops are less able to adapt to climate change and food shortages are already starting tooccur due to rapid population growth. Scientists at Stanford University and the University of Washington discovered that by 2100 there is a 90percent chance that the coolest temperatures in the tropics during the growing season will be higher than the hottesttemperatures recorded in those regions through 2006. Even more temperate parts of the world can expect to seepreviously record-high temperatures become the norm. With the world population expected to double by the end of the century, the need for food will becomeincreasingly urgent as rising temperatures force nations to retool their approach to agriculture, createnew climate-resistant crops, and develop additional strategies to ensure an adequate food supply for their people. All of that could take decades, according to Rosamond Naylor, who is director of food security and theenvironment at Stanford. Meanwhile, people will have fewer and fewer places to turn for food when their localsupplies begin to run dry
