D'Aleo's fundamental premise is that although there is a global warming trend there is not a strong causal relationship between that trend and carbon dioxide buildup in the atmosphere. Instead D'Aleo contends that the global warming trend correlates more closely with other phenomena such as solar activity and ocean current oscillations.

On October 20, 2006 D'Aleo registered the domain name for ICECAP, a website challenging human-induced global warming. [2]
