答案

Just as on smoking实际做了前置,实际顺序应该是 voices Just as on smoking now come from many quarters insisting that the science about global warming is incomplete
就同吸烟问题一样,来自许多领域的声音坚持认为有关全球变暖的科学研究还不完整
完整的句意：就同吸烟问题一样,来自许多领域的声音坚持认为有关全球变暖的科学研究还不完整,在我们确定此事之前向大气中继续排放废气是没问题的.
这个句子的主干是voices come from many quarters ,insisting 引导的是伴随状语,其后that引导的是insist的宾语从句,两个that引导的都是insist的宾语从句,简单说,这些声音坚持的一是全球变暖科学研究不完整,二是因为这个研究不完整,所以还坚持继续向大气中排放废气没问题.
just as on smoking中,just as 是副词,固定词组,意为正象,正如；on,这里意为关于、有关；smoking,意为吸烟.整句这里意为,正如吸烟问题.所以,just as和介词 on没有冲突.
smoking,本身就有名词词性,这里可以理解为动名词做名词使用.
原句没问题,不用加and ,两个that引导的都是宾语从句,主干谓语是insist,由于是伴随发生,所以,insist用现在分词形式.这里加上and反而违背语法.
just as smoking,这种说法可以,但意思有差别.
