Tiny quantities of more than thirty rare gases, most of them industrial by-products, threaten to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years.
(A) to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years (improper pacement of modifier)
(B) to warm the Earth’s atmosphere even more rapidly over the next fifty years than carbon dioxide will (OK)
(C) during the next fifty years to warm the Earth’s atmosphere even more rapidly than carbon dioxide (The same as A)
(D) a warming of the Earth’s atmosphere during the next fifty years even more rapid than carbon dioxide’s (threaten a warming => it could have been great if had been so)
(E) a warming of the Earth’s atmosphere even more rapid than carbon dioxide’s will be over the next fifty years (threaten a warming => it could have been great if had been so)

What is wrong with A?
B: if you have a MGMAT SC guide this looks very similar to Chap 5, modifiers page 75.
The group arrived in New Orleans and decided to stay in a fancy hotel a week before Mardi Gras...
Should be written as
The group arrived in New Orleans a week before Mardi Gras and decided to stay in a fancy hotel.
The second one is correct b/c the modifier "a week before..." describes when the group arrived.
In your sentence, A the modifier "during the next fifty years" should be placed closest to what it is trying to modify.

Tiny quantities of more than thirty rare gases, most of them industrial by-products, threaten to warm the Earth's atmosphere even more rapidly than carbon dioxide during the next fifty years.
(A) to warm the Earth's atmosphere even more rapidly than carbon dioxide during the next fifty years (B) to warm the Earth's atmosphere even MORE rapidly over the next fifty years THAN carbon dioxide will (C) during the next fifty years to warm the Earth's atmosphere even more rapidly than carbon dioxide (D) a warming of the Earth's atmosphere during the next fifty years even more rapid than carbon dioxide's (E) a warming of the Earth's atmosphere even more rapid than carbon dioxide's will be over the next fifty years
GMATNinjaTwo Does (B) correctly compare MORE rapidly.... THAN carbon dioxide WILL? I have no idea why do we need WILL at the end of the sentence.

Quantities threaten to warm atmosphere more rapidly than carbon dioxide.
Here you can deduce two meanings:
I. Quantities threaten to warm atmosphere more rapidly than Quantities threaten to warm carbon dioxide.
II. Quantities threaten to warm atmosphere more rapidly than carbon dioxide threaten to warm atmosphere
If you go by meaning then II is correct.
Now we know if can skip the words in parallelism if the meaning is not compromised. This is called ellipsis.
As you see "threaten to warm the atmosphere" is an action which is repeated twice in the sentence II. We can use verb WILL and elipse "threaten to warm the atmosphere", which can be understood.
Quantities threaten to warm atmosphere more rapidly than carbon dioxide WILL {threaten to warm atmosphere}
Ellipsis Trick: whenever you see parallelism in which some words or phrase is ellipsed then try to write out (in mind only ) the full sentence without skipping any word. This has more to do with the meaning and is widely tested in exam.
