As someone unfamiliar with the polar stratospheric clouds issue, two questions: Is this high-latitude warming effect observed after volcanic eruptions? Probably not - more likely dynamical effects arising from tropical heating in the lower stratosphere coupled with cooling in the troposphere beneath. How does this relate to the often-repeated claims that Greenland ice melting slowed after Mt. Pinatubo? I don’t know, but see above. My opinion is that direct radiative effects from PSCs in the Arctic polar vortex are unlikely to be large enough.
