Despite expectations of warming, temperature measurements of the upper 700m of the ocean from the ARGO array show no increase from 2003 through 2008. Willis calculates a net loss of -0.12 (±0.35) x 1022Joules per year (Pielke, Physics Today,55) from mid-2003 to the end of 2008 (Dr. Pielke received permission from Josh Willis to extend the ARGO data to the end of 2008). According to a recent analysis of ARGO data by Craig Loehle, senior scientist at the Illinois-based National Council for Air and Stream Improvement, the loss is -0.35 (±0.2) x 1022Joules per year from mid-2003 to the end of 2007 (see Loehle, 2009: “Cooling of the global ocean since 2003.? Energy & Environment, Vol. 20, No. 1&2, 101-104(4)). Loehle used a more complex method than Willis to calculate this trend, enabling him to reduce the margin of error. ......These figures reveal a robust failure on the part of the GISS model to project warming. The heat deficit shows that from 2003-2008 there was no positive radiative imbalance caused by anthropogenic forcing, despite increasing levels of CO2. Indeed, the radiative imbalance was negative, meaning the earth was losing slightly more energy than it absorbed. ..... Using Loehle’s deficit, the numbers are even more remarkable. Assuming that heating resumes for the next 4.5 years (2009 to mid 2013), the annual average accumulation of heat would need to be 2.73 x 1022 Joules in the upper ocean, for a 4.5 year total of 12.29 x 1022 Joules. The derived radiative imbalance for the upper ocean would increase to 1.7 W/m2, or nearly 3x higher than the projected imbalance. ..... Analysis and Conclusion Though other criteria, such as climate sensitivity (Spencer, Lindzen), can be used to test the AGW hypothesis, ocean heat has one main advantage: Simplicity. While work on climate sensitivity certainly needs to continue, it requires more complex observations and hypotheses making verification more difficult. Ocean heat touches on the very core of the AGW hypothesis: When all is said and done, if the climate system is not accumulating heat, the hypothesis is invalid.Writing in 2005, Hansen, Willis, Schmidt et al. suggested that GISS model projections had been verified by a solid decade of increasing ocean heat (1993 to 2003). This was regarded as further confirmation the IPCC’s AGW hypothesis. Their expectation was that the earth’s climate system would continue accumulating heat more or less monotonically. Now that heat accumulation has stopped (and perhaps even reversed), the tables have turned. The same criteria used to support their hypothesis, is now being used to falsify it. It is evident that the AGW hypothesis, as it now stands, is either false or fundamentally inadequate. One may argue that projections for global warming are measured in decades rather than months or years, so not enough time has elapsed to falsify this hypothesis. This would be true if it were not for the enormous deficit of heat we have observed. In other words, no matter how much time has elapsed, if a projection misses its target by such a large magnitude (6x to 8x), we can safely assume that it is either false or seriously flawed. Assuming the hypothesis is not false, its proponents must now address the failure to skillfully project heat accumulation. ....... On the other hand, the current lapse in heat accumulation demonstrates a complete failure of the AGW hypothesis to account for natural climate variability, especially as it relates to ocean cycles (PDO, AMO, etc.). If anthropogenic forcing from GHG can be overwhelmed by natural fluctuations (which themselves are not fully understood), or even by other types of anthropogenic forcing, then it is not unreasonable to conclude that the IPCC models have little or no skill in projecting global and regional climate change on a multi-decadal scale. Dire warnings about “runaway warming” and climate “tipping points” cannot be taken seriously. A complete rejection of the hypothesis, in its current form, would certainly be warranted if the ocean continues to cool (or fails to warm) for the next few years. Whether the anthropogenic global warning hypothesis is invalid or merely incomplete, the time has come for serious debate and reanalysis. Since Dr. Pielke first published his challenge in 2007, no critical attempts have been made to explain these failed projections. His blogs have been greeted by the chirping of crickets. In the mean time costly political agendas focused on carbon mitigation continue to move forward, oblivious to recent empirical evidence. Open and honest debate has been marginalized by appeals to consensus. But as history has often shown, consensus is the last refuge of poor science. wattsupwiththat.com
