I'm sorry, but these silly suggestions mean nothing.  Get some data and return to the big boys' table.  
"However, within two years, the ice was back!"  How much ice exactly did it lose and then gain and how fast?  Without numbers this is meaningless conjecture.  (PS: The earth has very quick cooling mechanisms in place - this can occur during huge caldera-forming volcanic eruptions, see Tambora and Krakatoa.  Quick heating on the other hand doesn't have a similarly rapid forcing mechanism.  Until now.)
