Global warming theorists now claim that Arctic sea ice melt causes colder and snowier winters - the empirical evidence indicates that it must also cause colder oceans, a definite AGW negative feedback

These Bob Tisdale charts of ocean temperatures through January 2012 are most enlightening. To summarize the data plotted on the charts, ocean temperatures, as represented by the Southern, South Pacific and global measurements, clearly show a decline since the 1998 El Niño event. The Southern Ocean (aka the Antarctica Ocean) has experienced a very significant decline in temperature since the early 2000's.
Sooo...per the logic of the typical global warming alarmist, the Arctic sea ice melt from human CO2 emissions does the following, from one Polar region to its geographic opposite:
- Increased CO2 ===> increases Arctic warming ===> increases Arctic sea ice melt ===> decreases solar albedo ===> increases summer temperatures ===> decreases winter temperatures ===> increases snow ===> decreases global ocean temperatures ===> decreases Antarctica Ocean temperatures ===> causes global cooling
In essence, the tortured logic of the ever-changing alarmist climate change theories literally leads one to conclude that global cooling weather events are the natural negative feedback to AGW.
Of course, no IPCC climate change report (so far) has remotely stated the above. But the actual climate empirical evidence (ie, non-warming world, lower ocean temps) and cold weather events has now forced CO2-centric global warming alarmists into a pretzeled logic that ultimately supports the overall negative feedbacks of global climate as understood by CAGW-skeptics, not the positive feedbacks pushed by the IPCC.
