Some climatologists, while admitting that the burning of fossil fuels have raised the level of CO2 in the atmosphere and have caused an increase in the level of global temperature, argue that both these effects are contributing to an abundance of plant mass and thereby leading to heightened consumption of CO2 levels, and bringing down the temperature

Can someone explain why A is wrong. I went think A: subject verb and parallelism - the fossil fuels have raised is correct in otion A and also parallelism is correct - the effects are contributing to -- and thereby leading to ---, and bringing down the temperature.

I am confused between D and E.
(D) Some climatologists, while admitting that the burning of fossil fuels raises the level of CO2 in the atmosphere and causes an increase in the level of global temperature, argue that both these effects contribute to an abundance of plant mass, thereby leading to heightened consumption of CO2 levels, and bringing down the temperature - is D better?
(E) Some climatologists, while admitting that the burning of fossil fuels raise the level of CO2 in the atmosphere and cause an increase in the level of global temperature, argue that both these effects are contributing to an abundance of plant mass and thereby leading to heightened consumption of CO2 levels, bringing down the temperature
Also, what is the role of thereby/ and thereby? Why is E incorrect?

I think the answer is E. There is a parallelism error in D. (D) Some climatologists, while admitting that the burning of fossil fuels raises the level of CO2 in the atmosphere and causes an increase in the level of global temperature, argue that both these effects "contribute" to an abundance of plant mass, thereby leading to heightened consumption of CO2 levels, and bringing down the temperature - is D better
All the other verbs are in ing form. Hence I think that the use of "contribute" is wrong.

If we take a close look at the options, we soon begin to see some clear errors emerge. Option E has an obvious subject verb disagreement, the ’ verb ‘have’ (plural) is being used with the noun ‘the burning of’ (singular). The confusion here seems to be that the sentence refers to ‘the burning of fossil fuels’. ‘fossil fuels’ is plural but it is not what the verb refers to. B makes a similar error by again pairing ‘the burning’ with a plural verb, ‘raise’. A also makes this mistake with the verb ‘have caused’. C suffers from a meaning error, ‘having bought down the temperature’ implies that the temperature is done dropping, when the sentence is supposed to mean that the heightened consumption of CO2 levels is currently bringing down the global temperatures.
Because 'raise' and 'cause' are not referring to plural subject fossil fuels but they are referring to singular subject 'burning of fossil fuels'. Therefore, 'raises' and 'causes' or 'has raised' and 'has caused' is is expected.

GMATNinja My bad regarding that...But I have a question regarding option D. Is this part : "...thereby leading to heightened consumption of CO2 levels, and bringing down the temperature..", doesnt the use of and leads to the thinking that the heightened CO2 consumption and temperatures brought down are 2 independent things? I thought the sentence actually means that "bringing down the temperature" is an effect of "heightened CO2 consumption"...Therefore I had selected E as the correct answer

Please help! Thanks again
Good question! I see your point. If I have a choice between, "Tim fell down the stairs, breaking his ankle," and "Tim fell down the stairs and broke his ankle," I'd have a preference for the first construction, since this sentence clarifies that he broke his ankle as a consequence of having falling down the stairs. The second sentence, on the other hand, makes it sound as though the actions might have been distinct, and maybe Tim broke his ankle later when something completely unrelated. However, I wouldn't say that the second sentence is definitively WRONG - it also seems reasonable enough to have poor Tim do both actions as parallel verbs.
I'd want to look for another decision point when comparing (D) and (E). Take another look at (E): "The burning of fossil fuels raise the level of CO2 in the atmosphere and cause..." The subject of the sentence, "the burning", is singular, but the associated verbs, "raise" and "cause", are both plural. So (E) has a definitive error, and it's out.

here in D see the words: abundance of plant mass, thereby leading . here thereby leading .... and bringing down modifies the plant mass. whereas in E O2 bringing down the temperature modifies the CO2 levels , which is wrong
