SFT brought these to my attention. Apparently there will be an open mic discussion about it sometime in the new year.
As an initial thought, aren’t they missing a couple of zeroes in that number? Like 5 of 'em?
This abstract deals with the effects of large amounts (~700 ˣ 10e24 Joules) of geothermal heat being slowly transferred across the seafloor for several hundred years. This is enough energy to heat the oceans by 125 °C if it was deposited instantaneously. The mechanism of how this geothermal heat is supplied to the seafloor is a separate topic that is not discussed here.
What makes this different than other “warm ocean” models is that they use a one-time ocean heating event during the Genesis flood. My model uses continuous heating for centuries, while the oceans also simultaneously cool by transferring thermal energy to the atmosphere.
I evaluate both models by doing an energy balance for the entire planet. For the one-time heating model, calculated ocean cooling rates are 21.6 to 31.4 °C per century, thus the ice age could have only lasted about 80 to 120 years.
For the multi-century geothermal heating model, the ocean temperature vs. heat loss is calculated for zero to 1,500 years after the flood. The model starts out with no (zero °C) post-flood ocean temperature increase. After about 200 years, the deep-water ocean temperature increase maximizes at about +15 °C. By 1,000 years post-flood, deep-water ocean temperatures are similar to today. I demonstrate that the geographical distribution of this seafloor heating makes little difference in the resulting climate.
Also discussed is a “maximum geothermal heat budget” that the climate can safely handle, which any proposed CPT model must comply with.
If significant amounts of geothermal heat were discharged into the deep ocean, warmed water would rise from the seafloor, disrupting the thermohaline circulation. An estimate of the flow rates and the post-flood ocean circulation pattern resulting from this scenario is provided. Additionally, this moving water can erode fine particulate matter from the ocean floor, thus sediment calculations are also provided.
Other post-flood impacts are discussed, such as the effect on the chemistry of ocean water. Hot water travelling through rocks can change (and be changed by) the physical and chemical makeup of those rocks (metamorphism). Hydrothermal vents are discussed, and also the formation of manganese nodules (secular science does not have a good answer to how these formed).
Groundwater Flow and the Resulting Heat Transfer from the Sea Floor, Immediately after the Genesis Flood
This abstract provides a multi-faceted solution method to the “Heat Problem after the Genesis Flood” which is defined as follows:
Most models of CPT require that large amounts of hot crustal material would be spread across the ocean floor during the flood, especially the Atlantic ocean. This would release so much heat as to possibly boil the oceans. Because of this problem, the genesis flood didn’t happen, and thus the bible is wrong and evolution is right.
It is argued that long amounts of time are required to transfer any significant portion of this heat, and it is proposed that this heat remained trapped under the seafloor for hundreds of years after the flood ended. Most of the extra heat was eventually dissipated via (the very slow process of) radiation from the upper atmosphere. Since crustal material is not in thermal contact with the upper atmosphere, an analysis of the methods of heat transfer is needed.
Under the circumstances resulting from CPT, it is demonstrated that hydrothermal groundwater convection beneath the seafloor is the limiting heat transfer method. The other two possible mechanisms to transfer heat across the seafloor (thermal conduction and magma convection) are also discussed, calculated, evaluated, and ultimately dismissed. Also dismissed is the idea that miracles were involved in removing this extra heat, and it is explained why the use of miracles in this situation is unnecessary and also theologically problematic.
Although hydrothermal convection via groundwater flow is the main focus of the abstract, it simply brings thermal energy across the seafloor. It must then be transferred to the upper atmosphere by Earth’s weather. The climate impacts of this new heat source are not discussed here.
