高考英语押题作文素材：气候变化损害东南亚农业

　　Economists and scientists are still debating how emissions will affect climate in Asia, though generally they agree that weather patterns should become more volatile. The ADB, for its part, said it believes Thailand, Vietnam and Indonesia will experience drier weather over the next several decades, with that pattern possibly reversing later in the century.

　　Annual mean temperatures in those countries and the Philippines could rise by as much as 4.8 degrees Celsius by 2100 compared with 1990 levels, while sea levels could increase by 70 centimeters.

　　Those changes, especially the higher temperatures and a rising incidence of storms, could combine to cut rice yields and otherwise damage crops, the ADB said.

　　In debates on global climate change, Southeast Asia has traditionally received less scrutiny than other areas because it remains a relatively small contributor to greenhouse-gas emissions, accounting for about 12% of the world's total. But the region's role as a key supplier of rice and other agricultural commodities means any negative impact on farming could have big ripple effects, driving food prices higher.

　　Indeed, the ADB report is only the latest in a series of papers arguing that climate changes related to emissions will reduce world food production. The Food and Agriculture Organization of the United Nations has warned of increased risk of crop failures from floods and other weather changes, as well as the emergence of new pests and diseases that only flourish at specific temperatures and humidity.[来源:学,科,网]
