参考答案
正确答案：B
解析：根据题干关键词declared，United Nations scientific panel定位到原文第一段首句：Recently, the United Nations scientific panel studying...declared that the evidence of a warming trend is "unequivocal". human activity has "very likely" been the driving force in that change over the last 50 years. 可知联合国科研小组发现全球变暖的迹象很明显，并且人类活动很有可能是全球变暖的推动力，B)项符合义意。
