NO correlation between the shifts in the net flow of heat in oceans and atmospheric carbon dioxide concentration

A very interesting study by David Douglass, professor of physics and Robert Knox, emeritus professor of physics at the University of Rochester. They have studied the net flow of heat into and out of the oceans and its effects on the global climate.

 “These shifts in the balance of heat absorbed from the sun and radiated from the oceans correlate well with past anomalies that have been associated with abrupt shifts in the earth’s climate, say the researchers. These anomalies include changes in normal storm intensities, unusual land temperatures, and a large drop in salmon populations along the western United States.

…,the team says their data shows the oceans are not continuously warming—a conclusion not consistent with the idea that the oceans may be harboring ”warming in the pipeline.” Douglass further notes that the team found no correlation between the shifts and atmospheric carbon dioxide concentration.

An interesting aspect of this research is that no reference to the surface temperature itself is needed,”

Changes in Net Flow of Ocean Heat Correlate with Past Climate Anomalies

Physicists at the University of Rochester have combed through data from satellites and ocean buoys and found evidence that in the last 50 years, the net flow of heat into and out of the oceans has changed direction three times.

These shifts in the balance of heat absorbed from the sun and radiated from the oceans correlate well with past anomalies that have been associated with abrupt shifts in the earth’s climate, say the researchers. These anomalies include changes in normal storm intensities, unusual land temperatures, and a large drop in salmon populations along the western United States.

The physicists also say these changes in ocean heat-flow direction should be taken into account when predicting global climate because the oceans represent 90 percent of the total heat in the earth’s climate system.

The study, which will appear in an upcoming issue of Physics Letters A, differs from most previous studies in two ways, the researchers say. First, the physicists look at the overall heat content of the Earth’s climate system, measuring the net balance of radiation from both the sun and Earth. And second, it analyzes more completely the data sets the researchers believe are of the highest quality, and not those that are less robust.

These shifts happened relatively abruptly,” says David Douglass, professor of physics at the University of Rochester, and co-author of the paper. ”One, for example, happened between 1976 and 1977, right when a number of other climate-related phenomenona were happening, such as significant changes in U. S. precipitation.”

Douglass says the last oceanic shift occurred about 10 years ago, and that the oceans are currently emitting slightly more radiation than they are receiving.

The members of the team, which includes Robert Knox, emeritus professor of physics at the University, believe these heat-flux shifts had previously gone unnoticed because no one had analyzed the data as thoroughly as the Rochester team has.

The team believes that the oceans may change how much they absorb and radiate depending on factors such as shifts in ocean currents that might change how the deep water and surface waters exchange heat. In addition to the correlation with strange global effects that some scientists suspect were caused by climate shifts, the team says their data shows the oceans are not continuously warming—a conclusion not consistent with the idea that the oceans may be harboring ”warming in the pipeline.” Douglass further notes that the team found no correlation between the shifts and atmospheric carbon dioxide concentration.

An interesting aspect of this research is that no reference to the surface temperature itself is needed,” says Knox. ”The heat content data we used, gathered by oceanographers, was gleaned from temperature measurements at various ocean depths up to 750 meters.” The team also found that the radiative imbalance was sufficiently small that it was necessary to consider the effect of geothermal heating. Knox believes this is the first time this additional source of heat has been accounted for in such a model.

The team notes that it’s impossible to predict when another shift might occur, but they suspect future shifts might be similar to the three observed. Both Douglass and Knox are continuing to analyze various climate-related data to find any new information or correlations that may have so far gone unnoticed.

    Ytterligare en spik i kistan för AGW-hysterikerna. Solen som samverkar med haven styr klimatet. Mänskliga CO2-utsläpp spelar en marginell roll.

    Om inte Reinfeldt byter kurs snart kommer han att likna Bagdad-Bob. Men Reinfeldt har utsett partiska personer till rådgivare. Nu ska Reinfeldt bli hjälte i Köpenhamn (tror han). Men Indien och Kina m.fl. kommer inte att acceptera EU:s tokerier.

      Per,

      Tyvärr så kommer Reinfeldt inte frivilligt att överge sin PK linje. Utan att köra den så länge det är ”gångbart” och tills det inte går längre. Då, och först då, så kommer han att helt bekymmerslöst byta linje och svänga 90-180 grader och glatt fortsätta i en ny riktning.

      Och helt ogenerat låtsas som om det regnar och att INGENTING av det han sagt eller gjort de senaste åren egentligen har hänt.

      Så går det tyvärr till i politiken. Jag har sett det på nära håll så många gånger under så många år.

      De räknar helt fräckt (och tyvärr oftast helt korrekt) med att vi väljare snabbt glömmer alla galenskaper som beslutats och genomförts.

      Global Warming Hysterin har, som både du och jag vet, ingenting med vetenskap och fakta att göra utan har blivit ett politiskt redskap för vissa krafter som indirekt vill omdana vårt samhälle.
