The problem with the anthropogenic GHG hypothesis is that one cannot use it to make consistent predictions about present or past climate events. Until the scientist can formulate the anthropogenic GHG hypothesis in a way that makes accurate predictions, it is impossible to make scientific statements about the effects of green house gases on the climate.

Funny how the world global temperature now is exactly where the IPCC predicted for CO2 emissions in 1991, 1997, 2001 and exactly what Hansen said in 1989 to the USA. That is GHG theory has been directly tested observations for the last 17 years and is proving accurate so far.
Maybe you want GHG theory to tell you its going rain next week.
This warming is uniquely fast and accelerating, this is statement is from observational evidence, models with GHG predict this remarkable warming event those without and don't. All the natural forcings which continuously cause our climate to swing from hot to cold have been present for a long time and there hasn't been an event like this before. As the climate is a chaotic system with positive feedback loops in both directions (hot and cold) changes in how much heat we receive from the sun led most of the climate changes the world has gone through this is clear and accepted by anyone with any knowledge of the climate and GHG theory, it is a mute point.
