A new study shows that the limit of the effects of longwave radiation caused by greenhouse gases extends only to about 10 microns (0.01 millimeters) of the skin layer (the ocean-air interface) and no deeper.
Determining sea surface temperature (SST) changes at this surface depth is critical to any attempt to quantify or calculate the effects of greenhouse gases such as carbon dioxide on ocean temperatures.
However, scientists admit that measuring such temperature changes at this depth is “impossible”.
Instead, temperature changes in the skin layer must be “planned” (i.e. guessed) only use the model start Layer depth is 500 to 1,000 mm (0.5 to 1.0 m).
Of course, this means The effect of carbon dioxide on ocean temperatures is also unmeasurable.
“The sea temperature at the interface is virtually unmeasurable”
“…the excessive vertical resolution does not allow direct modeling of skin SST (the first model layer is only about 0.5 – 1.0 m thick”…). Therefore, a protocol must be used to reconstruct cutaneous SST changes.
The paper’s authors don’t even mention changes caused by greenhouse gases as a contributing factor — let alone drive – Changes in ocean heat flux at the interface.
The only factors mentioned in determining changes in the energy of the air-sea system that are critical to “global warming” are changes in solar radiation and wind speed.
“The net energy flux across the air-ocean interface consists of four components: net solar radiation, latent and sensible heat fluxes, and net thermal radiation. The last three contributions depend on sea surface temperature and have a direct impact on determining ocean heat absorption …”
“Under low surface winds (less than 2 milliseconds), the diurnal warming amplitude of surface SST increases.−1 ) and intense solar radiation (above typical daily peaks, around 900 W/m²) conditions…”
Defenders of anthropogenic global warming (AGW) hypothesize that greenhouse gas-induced changes in descending longwave radiation (DLWR) can affect changes in thermal gradients deep within the surface layer, thereby reducing or enhancing cooling.
However, in a 2006 blog post for RealClimate, Dr. Peter Minnett reported the results of a 2004 experiment that used cloud-induced changes in DLWR as a proxy for CO2-induced changes in DLWR.
Using the cloud as a proxy is because The long-wavelength effects of carbon dioxide are too small to detect because they are thought to be 50 times smaller than the long-wavelength effects of clouds.
The experimental results revealed For a change in cloud cover of approximately 100 W/m² DLWR, the thermal gradient changes by only 0.002°C (two thousandths of a degree).
Since cloud forcing is 50 times greater than CO2 forcing (about 2 W/m² since 1750), the impact of CO2 (dividing the 0.002°C cloud value by 50) is 0.00004°C. This is four hundred thousand degrees.
This concrete quantification shows how absurd it is to believe that carbon dioxide could be a causal mechanism—let alone a causal mechanism. drive Mechanism—Global ocean temperature changes.
