Climate Science encourages guest weblogs from all perspectives of the climate science issue. Following is a guest weblog by William DiPuccio, who, although not a published climate scientist, has provided a view on the global warming discussion which is worth reading. Guest Weblog By William DiPuccio The Global Warming Hypothesis Albert Einstein once said, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” Einstein’s words express a foundational principle of science intoned by the logician, Karl Popper: Falsifiability. In order to verify a hypothesis there must be a test by which it can be proved false. A thousand observations may appear to verify a hypothesis, but one critical failure could result in its demise. The history of science is littered with such examples. A hypothesis that cannot be falsified by empirical observations, is not science. The current hypothesis on anthropogenic global warming (AGW), presented by the U.N.’s Intergovernmental Panel on Climate Change (IPCC), is no exception to this principle. Indeed, it is the job of scientists to expose the weaknesses of this hypothesis as it undergoes peer review. This paper will examine one key criterion for falsification: ocean heat. Ocean heat plays a crucial role in the AGW hypothesis, which maintains that climate change is dominated by human-added, well-mixed green house gasses (GHG). IR radiation that is absorbed and re-emitted by these gases, particularly CO2, is said to be amplified by positive feedback from clouds and water vapor. This process results in a gradual accumulation of heat throughout the climate system, which includes the atmosphere, cryosphere, biosphere, lithosphere, and, most importantly, the hydrosphere. The increase in retained heat is projected to result in rising atmospheric temperatures of 2-6ºC by the year 2100. In 2005 James Hansen, Josh Willis, and Gavin Schmidt of NASA coauthored a significant article (in collaboration with twelve other scientists), on the “Earth’s Energy Imbalance: Confirmation and Implications” (Science, 3 June 2005, 1431-35). This paper affirmed the critical role of ocean heat as a robust metric for AGW. “Confirmation of the planetary energy imbalance,” they maintained, “can be obtained by measuring the heat content of the ocean, which must be the principal reservoir for excess energy” (1432). ~snip~ Poster Comment: There is much more including formulas at the original post.
