I used "any" in sentence # 1 but as the dictionary says "impact" can be either countable or uncountable I don't understand when to use it as a countable noun and when as an uncountable noun. If I change the sentence # 1 and say "she believes it has an important impact/important impact on the environment" should I use it with the indefinite article?
"Carbon dioxide doesn't have any/some significant impact on global temperatures.
I mean if I removed "an" and used it in a general sense would it be wrong? I mean in the same way as "effect." With or without the indefinite article: Had an effect = had one/a particular (countable/specific) effect had any effect = had any degree of (uncountable/abstract) effect.
