While the polar stratospheric clouds could explain the reduction of the equator to pole temperature gradient and the increased temperatures at the poles during the early Eocene, there are a few drawbacks to maintaining polar stratospheric clouds for an extended period of time.

Susan Solomon, an atmospheric chemist at the National Oceanic and Atmospheric Administration ( NOAA ), proposed that chemical reactions on polar stratospheric clouds ( PSCs ) in the cold Antarctic stratosphere caused a massive, though localized and seasonal, increase in the amount of chlorine present in active, ozone-destroying forms.

According to the European Science Foundation, which is based in Strasbourg, France, the M-55 provided by the Myasishchev Design Bureau, the Russian Central Aereological Center and Aviecocenter will be able to study the chemical reactions believed to occur on the surfaces of fine ice particles that make up polar stratospheric clouds.
