James Hansen and NASA predicted that 'business-as-usual' CO2 emissions growth would cause significant and accelerating warming - the latest empirical evidence confirms that their climate models were wildly wrong

Back in 1988, Hansen's climate model predicted rapid warming if CO2 emissions continued to grow as they had in the past. For the previous 15 years prior to 1988, human produced 285 billion tons of CO2 emissions, an increase that was about 2.1% per year.
Not only did humans maintain a 'business-as-usual' growth in succeeding years, they actually spewed out 1.5 times more CO2 emissions over the 15 years ending 2012. That amounted to an average increase of about 2.8% per year. These results come from the latest CO2 emission data that was just published during June 2012.
As the two top charts indicate, human civilization showed an utter lack of respect for 'the business-as-usual' scenario as less developed countries started their climb to levels of modern civilization. The end result being a huge increase in CO2 emissions.
Per the James Hansen powerful and super-sophisticated climate models though, this gigantic spewing of CO2 emissions should have produced a large, significant upswing in global warming, but it hasn't.
The bottom chart on the left is the representation of the NASA-Hansen climate model. The chart's green curve represents the predicted global temperatures if 'business-as-usual' (BAU) CO2 emissions continued since 1988. The large red dot is the predicted BAU temperature for year 2011. Look closely....Oooops!
On the same chart, the green dots connected by black lines are the actual temperatures, which (obviously) are substantially below the "BAU" curve. The green dots are even below the aqua curve, which is the temperature prediction if CO2 emissions had stopped growing in year 2000.
The same chart includes the IPCC's gold-standard temperature dataset (the pink dots) that also is well below the BAU prediction of the climate models. This temperature dataset's (HadCRUT global) lack of "global warming" over the last 180 months can also be seen here.
The bottom chart on the right is another depiction of the literal absence of the predicted "global" warming, despite the gargantuan 429 billion tons of CO2 emissions ejected into the atmosphere. As the chart reveals, some parts of the world are warming, some are cooling and some areas are unchanging. And six months from now, that chart will reveal the same outcomes, but with different areas warming and cooling.
