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.
