In a post here, I pointed out that surface temperatures have not increased in the past 15 years, that all of the IPCC climate models had failed, and that the warmies' AGW theory, that temperatures will increase in direct proportion to the amount of CO2 pumped by humans into the atmosphere, had proven false. Indeed, today, AGW theory rests on a single untested hypothesis from warmie scientist Kevin Trenberth. As I quoted Trenberth from his essay in the WSJ:
[C]omputer models have recently shown that during periods when there is a smaller increase of surface temperatures, warming is occurring elsewhere in the climate system, typically in the deep ocean. Such periods are a relatively common climate phenomenon, are consistent with our physical understanding of how the climate system works, and certainly do not invalidate our understanding of human-induced warming or the models used to simulate that warming.
Trenberth had written the above in response to an essay by sixteen sceptic scientists, "No Need to Panic About Global Warming,". Those same scientists have now responded to Trenberth's essay, including his claim that global warming is continuing, just only in the deep ocean. This from the WSJ:
[A]n important gauge of scientific expertise is the ability to make successful predictions. When predictions fail, we say the theory is "falsified" and we should look for the reasons for the failure. Shown in the nearby graph is the measured annual temperature of the earth since 1989, just before the first report of the Intergovernmental Panel on Climate Change (IPCC). Also shown are the projections of the likely increase of temperature, as published in the Summaries of each of the four IPCC reports, the first in the year 1990 and the last in the year 2007.
The Trenberth letter tells us that "computer models have recently shown that during periods when there is a smaller increase of surface temperatures, warming is occurring elsewhere in the climate system, typically in the deep ocean." The ARGO system of diving buoys is providing increasingly reliable data on the temperature of the upper layers of the ocean, where much of any heat from global warming must reside. But much like the surface temperature shown in the graph, the heat content of the upper layers of the world's oceans is not increasing nearly as fast as IPCC models predict, perhaps not increasing at all. Why should we now believe exaggerating IPCC models that tell us of "missing heat" hiding in the one place where it cannot yet be reliably measured—the deep ocean?
