ACCORDING to the anthropogenic global warming (AGW) hypothesis while surface temperatures may vary from year to year, as long as we spew out carbon dioxide there will be a gradual accumulation of heat in the climate system eventually resulting in a climate crisis.
In 2005, NASA boss James Hansen stated in an article in the journal ‘Science’ that confirmation of the planetary energy imbalance can be obtained by measuring the heat content of the oceans which are the principal reservoir for excess energy.
A problem for the AGW hypothesis now, is that the oceans have been cooling. Indeed there is no known mechanism to account for what some describe as vast amounts of missing heat, suggesting that contrary to the AGW hypothesis, heat is not accumulating in the climate system and there is no longer any radiative imbalance from all the carbon dioxide and other greenhouse gases.
According to William DiPuccio, in a guest post at the blog ‘Climate Science’, this not only demonstrates that the United Nation’s Intergovernmental Panel on Climate Change models are failing to accurately predict global warming, but also presents a serious challenge to the integrity of the AGW hypothesis.
Mr DiPuccio concludes “When all is said and done, if the climate system is not accumulating heat, the hypothesis is invalid.”

Have Changes In Ocean Heat Falsified The Global Warming Hypothesis? – A Guest Weblog by William DiPuccio
The graph by Mr DiPuccio shows the increasing deficit of upper ocean heat from 2003 through 2008 based on GISS projections. Actual heat accumulation is plotted from observed data (using ARGO) and shows the overall linear trend (after Willis and Loehle). Seasonal fluctuations and error bars are not shown.
Mr DiPuccio notes in the above article that: Heat is not the same as temperature. Two litres of boiling water contain twice as much heat as one litre of boiling water even though the water in both vessels is the same temperature. A larger container has more thermal mass which means it takes longer to heat and cool.
William DiPuccio was a weather forecaster for the U.S. Navy, and a Meteorological/Radiosonde Technician for the National Weather Service. More recently, he served as head of the science department for St. Nicholas Orthodox School in Akron, Ohio (closed in 2006). He continues to write science curriculum, publish articles, and conduct science camps.
