rmdg, 
You will have to do better than that. 
The ice age ended, I am not sure, 15000 years ago give or take. Socialism probably appeared on the World stage as an active force about 1918, the fall of Imperial Russia.  
The past was Imperial glory,that went back to Babylon and beyond, can't get your connection between the ice age and socialist dreaming. 
To the historians I apologize for lack of historical exactness.
