Now, where exactly in this citation (or elsewhere in this article) does NASA say-or even imply-that the reduction in Earth's aerosols is the SOLE reason why our planet is warming...which is what your added headline (conclusion) implies?

(Hint - It doesn't...because greenhouse gases are ALSO a forcing factor in the Earth's surface temperature. If CO2 and other gases didn't ACT as greenhouse gases, then why should they be called "greenhouse gases" in the first place?)
