Just as on smoking, voices now come from many quarters, insisting that the science about global warming is incomplete, that it\'s Ok to keep pouring fumes into the air until we know for sure。

个人分析:voices now come from many quarters是本句的主干,句首的just as作比较状语。Insisting这个粉刺作定语修饰voices,可能是该句的难点。同时分词结构中还含有两个并列部分,即由that引导的宾语从句。
