As the confetti settles, the park that announced the “beginning of the 21st century” is now suffering a post-millennial hangover.
Journey Into YOUR Imagination is underfunded and it’s designers are ill-equipped (and perhaps ill-experienced) to deal with the enormous pressure to deliver a quality attraction with an impossibly short deadline.
Besides, blaming a of warming on humans just seems a little bizarre.
The dark line in the above plot is the 44-model average, and it approximately represents what the IPCC uses for its official best estimate of projected warming.
This is exactly what would be predicted with lower climate sensitivity.
On the other hand, if Trenberth is correct (explanation #2), then there should be a period of rapid surface warming that resumes at some point, since the climate system must eventually try to achieve radiative energy equilibrium. Explanation #3 (anthropogenic aerosol cooling), while theoretically possible, has always seemed like cheating to me since the magnitude of aerosol cooling is so uncertain it can be invoked in any amount desired to explain the observations.
