①停止使用煤、石油、天然气等能源②研究提高能源利用技术和能源利用效率

③扩大海洋面积,调节气温④积极开发采用新能源;加强国际间的合作

⑤增强人们的环保意识;植树造林,保护好现有的原始森林

A. ①③⑤ B. ②④⑤ C. ②③④ D. ①②④

【答案】B

【解析】

根据气候与人类活动的关系进行分析解答。

煤炭、石油、天然气等矿产资源,应尽可能综合利用,注意节约。故错误;②研究提高能源利用技术和能源利用效率,发展以低能耗、低污染、低排放为基础的低碳经济,具有十分重要的意义。故正确;③地球变暖造成世界海平面上升,沿海城市将面临被淹没的灾难。故错误;④新能源普遍具有污染小、储量大、分布广的特点。积极开发利用新能源,加强国际间的合作是防止全球变暖的重要途径。故正确;⑤植树造林,可以使当地气温的变化趋于缓和。如果任意砍伐森林,则可能使当地气候恶化。故正确故选:B。
