WOOT!Damn you two, Buried my well thought out response under pages of arguing LOL
the sun contributes most to warming of ocean temps. by far.
Absolutely false. The ocean is warmed by the earth first, atmosphere and solar radiation are second and third tho none of us knows the exact order until we have further data.
The earth is a several thousand degree hot rock that is actually touching the ocean along a large surface area, whereas the sun is a much hotter rock 108 million miles away and most of the suns' energy never reaches the surface of the earth because the atmosphere gets first access to that energy.

Wow!
the atmosphere cant leverage heat transfer on water. 1000:1 the effect will go the other way.
It doesn't make any difference if water transfers heat into the atmosphere 1000 times more readily, what matters is which is warmer, the ocean or the atmosphere. If the atmosphere is warmer than it will heat the oceans, period.
Heat transfer works two ways: a cold window can radiate cold just as readily as a hot window can radiate heat. In fact a window always does both at once. IF there is a temp differential between inside and outside.
Which brings us back to which is warmer the mean ocean surface temp or the mean surface atmosphere temp?
false. water does not give away heat readily. few other substances can hold heat like water. few others wick heat like water.
Actually you are deeply confused on this point.
NOTHING gives away heat as well as water, at least no common material. And there is a VERY simple way that you can prove this to yourself.
Stick your hand into an oven that is heated to 212 degrees
then stick your hand into water heated to boiling
then pick up a piece of aluminum, copper and then steel all heated to the exact same temp.
In order you will receive the worse burn by far from the water, then the copper, aluminum, steel and the oven won't even phase you.
Water gives away heat AND absorbs heat with EXACTLY the same efficiency.
Which is why water is the premium liquid to use in your truck's cooling system. It absorbs heat from the engine faster than anything else and releases that heat thru the radiator faster than anything else. If you add antifreeze to the system that efficiency drops, but the water won't corrode your engine or freeze.
I am curious why you mentioned thermodynamics since heat transfer is not an energy conversion and therefore not covered by the laws of thermodynamics.
It is covered by the conservation of energy principle.
~174,000,000,000,000,000joules from the sun constantly bombard the planet. 47,000,000,000,000joules come from geothermal sources. the sun contributes 3700 x the energy than the earth does.
You better prove that because I absolutely can not imagine it is true.
The solar constant includes all types of solar radiation, not just the visible light. It is measured by satellite to be roughly 1.366 kilowatts per square meter (kW/m²)..... Thus, for the whole Earth (which has a cross section of 127,400,000 km²), the power is 1.740×1017 W, plus or minus 3.5%.
The mean heat flows of continents and oceans are 65 and 101 mW m−2, respectively, which when areally weighted yield a global mean of 87 mW m−2 and a global heat loss of 44.2 × 1012 W, an increase of some 4–8% over earlier estimates.
As per water you seem to have a remarkably strong attachment to a complete misunderstanding of how water reacts with heat.
People are more than 70% water, you tool.
Aside from that, animal physiology and reaction to temperature changes is vastly different from that of largely inorganic matter, like air and water....You can sit in a 190° dry sauna for a short while because your skin can evaporate water off quickly enough to maintain its cellular integrity.
Your knowledge of both meteorology and human physiology couldn't fill the cover of a matchbook.
I just posted a link asserting that sitting in a 212 degree sauna is leisurely and relaxing.
And it simply makes no difference what the human skin does with heat since the same human skin is exposed to equally warm water, metal and air in my thought experiment.
The experiment accurately gauges the thermal conductivity of the materials involved in the experiment.
But I can provide you with data if you doubt me. Thermal conductivity is the exact opposite of insulative (R) values, so there are two ways that you or I can look em up.
Dood, (mispelled in deferance to The Dude)
You need to get your facts from a source other than wiki. That site will get you killed! For your information 212 F is the temp they use for the world championships and it is not a relaxing situation! It is an endurance competition that lasts minutes and almost allways results in some form of injury.
This year there was a fatality.

You started off OK in this thread but you have rapidly gone downhill since.

3700 x the energy comes from the sun than comes from geothermal sources. talk about absolutely false.

no. What matters is the amount of energy. This is what allows a pot of hot water to heat a whole room of air.
See "sensible heat". Basic thermal dynamics.

this is relative sensible heat. giving away heat is not an accurate way of looking at heat transfer between materials. sensible heat looks at the amount of energy required to raise the temp of a substance and is perfectly inverse to the amount of energy absorption required to cool it. the extra heat you experience with the hand in the boiling water is the sensible heat leverage of water... the greater energy which it releases.
there is more energy in every temperature degree of water than there is in most other substances.
I am curious why you mentioned thermodynamics since heat transfer is not an energy conversion and therefore not covered by the laws of thermodynamics.
It is covered by the conservation of energy principle.
heat transfer is part of thermal dynamics. the first two laws of thermal dynamics relate to heat transfer.
i'm curious if you've ever studied thermal dynamics formally or extensively on your own.

from wiki on the solar constant:

As per water you seem to have a remarkably strong attachment to a complete misunderstanding of how water reacts with heat.
maybe the misunderstanding is on your part. i think you are confused about the significance of water's high latent and sensitive heat. this is the point that i have been harping on with respect to water's 'leverage' over other materials. check out these terms; holla back.

so a 60 yo guy died after sitting in a 212 degree sauna for 6 minutes.
I WIN! Thanks for the corroborating link!

But YOU were claiming that water had this unique ability to resist giving up it's heat! Now you are backtracking! Which is it?

I know what latent heat in water is, I described it to you several pages ago, but I can't find any web reference to sensitive heat.
Regardless of that I can't figure out what your point is regarding warming because you keep changing your assertions.
I am curious why you mentioned thermodynamics since heat transfer is not an energy conversion and therefore not covered by the laws of thermodynamics.

heat transfer is part of thermal dynamics. the first two laws of thermal dynamics relate to heat transfer.

Heat is the inefficiency by product of energy conversions. That's what the laws of thermo dynamics assert. Heat transfer from material to material is not a conversion of energy, and is subject to 100% conservation of energy.
Yes you certainly "win" if you think dying is relaxing. Epic fail dood, epic fail.
