If I am correct we are not at the end of one of those phases. We are at
the beginning. Climatic disasters will continue to occur each year until
the Arctic ice has gone completely and the climate has settled into a
new patern of clouds.

Playing devil's advocate, do we understand these processes so well
that we can discount the following scenario?

Melting ice/increased wv/ increased global temperatures prompt a much
more rapid increase in cloudiness than anticipated, a cloudiness
"flip" or overshoot, if you lke. This quickly increases the overall
albedo, overwhelming the initial relative warmth... and is followed by
rapid global cooling.
