This makes the global warming models even wronger :) If the models were correct they would predict even more warming the since 1995 than they actually did predict. That is, if you add a new, and additional, positive feedback caused by warming (methane), then the models should predict more warming than they currently predict.
But the models were already grossly over predicting temperatures. So they are even wronger than we thought they were.
Not sure the models even include the effects of clouds...
