You have three errors in your lecturing. We take them one by one.
No, the surface temperature is not primarily due to the temperatures at the Earth's core. Study the "radiation budget", here is a link. This is very well established science.
Here is the answer from a prime "warmer resource,"
http://www.skepticalscience.com/heatflow.htmlCommon sense might suggest that all that heat must have a big effect on climate. But the science says no: the amount of heat energy coming out of the Earth is actually very small and the rate of flow of that heat is very steady over long time periods. The effect on the climate is in fact too small to be worth considering.Here is a brief discussion of the energy budget.
http://missionscience.nasa.gov/ems/13_radiationbudget.htmlNext, interglacials caused by ocean currents? No, they are not. It is well established that they are the product of periodic variation in the Earth's orbit.
The interglacials and glacials coincide with cyclic changes in the Earth's orbit. Three orbital variations contribute to interglacials. The first is a change in the Earth's orbit around the sun, or eccentricity. The second is a shift in the tilt of the Earth's axis, the obliquity. The third is precession, or wobbling motion of Earth's axis.[1] Warm summers in the northern hemisphere occur when that hemisphere is tilted toward the sun and the Earth is nearest the sun in its elliptical orbit. Cool summers occur when the Earth is farthest from the sun during that season. These effects are more pronounced when the eccentricity of the orbit is large. When the obliquity is large, seasonal changes are more extreme.[2]https://en.wikipedia.org/wiki/InterglacialFinally, you have a rather interesting statement.
... making it hotter
will change salinity
which will change ocean currents
which will influence the beginning of the Ice Age.
No scientific findings support the certainty in your statement (bolded.) They cannot, because this is outright speculation. Here is the statement corrected to a reasonable level.
...
IF CO2 produced by man makes the Earth hotter this
MIGHT CHANGE salinity
which MIGHT AFFECT ocean currents
which MIGHT influence the beginning of the Ice Age.
That's obvious speculation, why not just state it as such? Obviously it isn't factual or supported by scientific findings. It's totally reasonable to discuss as speculation, but it's unacceptable to consider or promote as fact.
At least you're trying to discuss.
1/ This point was to make you understand that the most important is not the total heat but how it's distributed. Earth core heat is reponsible for the most part of energy dissipated on our ground BUT has low impact on climate because it's very equally distributed. It just provides a "base temperature" everywhere of something like 200°.
2/"Next, interglacials caused by ocean currents? No, they are not. It is well established that they are the product of periodic variation in the Earth's orbit."
That would be true if we were sure that only that cause Ice Age. But we're absolutely not. Variations of Sun activity, Earth's orbit and salinity of oceans. All of them have an impact. Of course Earth's orbit is a FUCKING IMPORTANT one that's for sure. But not the only one to consider, and at similar Earth's orbit, you might have or not an ice age depending on other factors such as salinity.
3/ Ok fair point. You're perfectly right as it is speculation. But not based on nothing, it's based on simulation. Of course simulations are by themselves outrageous speculations as you try to create a model of reality, which will never be complex enough to be sure of yourself.
1. Um, no, Earth's core is not responsible for the major part of energy dissipated. Please help me out a bit here, just check the facts before posting.
Despite its geological significance, this heat energy coming from Earth's interior is actually
only 0.03% of Earth's total energy budget at the surface, which is dominated by 173,000 TW of incoming solar radiation.
https://en.wikipedia.org/wiki/Earth's_internal_heat_budget2. A necessary condition is the orbital changes, and that is a necessary and sufficient condition. Changes in incoming radiation overpower things such as salinity. In fact, changes in salinity occur randomly and chaotically in a chaotic system, don't they? There is no argument here to be made regarding salinity as a driving force behind ice ages. In fact, it's not the salinity but the changes in ocean currents, isn't it? And those are not static and certainly will change with time.
3. Arguing simulation of a mathematically chaotic system? You really want to go down that road?
Instead of focusing on an issue of the type IF A THEN IF B THEN IF C THEN IF D MAYBE....
Why not just stick to reasonable certainties? IF WE GET HIT BY A BIG ROCK FROM SPACE WE ARE FUCKED.
Let's call the above an 4IF argument. Fair enough? Is this what you've got in support of AGW?
LOL...any reasonable person would demand far better than that. Because we can prove almost anything using a 4IF dialectic.
