The subject in this sentence is "The aspects", which is plural, hence "are" is the correct verb.
This will rule out options B and D.
Next is the concept of parallism.
*That* the polar ice caps.... *That* the seas.... And *That* violent weather...
Since the non underlined portion already starts with a 'That', to maintain the parallel structure, the clauses in the underlined portion must also start with a 'that'
This rules out A and C
Hence E is the correctanswer.
