I wonder if the earths core temperature is responsible for temperature variation?

Question

I'd read something like that, Kent M, thanks for the link.

Answer 1

unlikely because of the crust.  The core is hot because of the sheer amount of weight pushing down on it from above.  At the crust, especially the surface of the crust, there is low pressure.  The only area where heat would be emanating from would be volcano's and areas where the crust is pulling apart like at the mid Atlantic ridge, which is basically a long volcano.

Answer 2

Our Sun is the dominating energy source in our solar system. The heat from our Sun is being trapped on one hand, the green house effect promoting global warming and on the other, blocked due to global diming as sunlight is reflected back into outer space. This is because fossil fuel use, as well as producing greenhouse gases, creates other by-products. These by-products are also pollutants, such as sulphur dioxide, soot, and ash. These pollutants however, also change the properties of clouds. Clouds are formed when water droplets are seeded by airborne particles, such as pollen. Polluted air results in clouds with larger number of droplets than unpolluted clouds. This then makes those clouds more reflective. More of the sun’s heat and energy is therefore reflected back into space. The irony is that global dimming is offsetting the effects of global warming, but there are health and environmental issues as a result of the airborne pollutants that lead to global dimming. Global dimming itself may have already claimed millions of lives by way of famines due to climate change. So my answer to your question is no, after considering the other more dominant variables.

Answer 3

Probably not, but there is a magma "hotspot" underneat the area where the Greenland ice sheet is melting......

Answer 4

Not nearly to the extent that the sun is... contrary to what some global warming radicals will tell you...

Answer 5

Another stupid global warming question that is based on a false assumption by someone who has never had a science class.

NO... the earth's core temp is NOT RESPONSIBLE

Answer 6

No.  It is not significant. There are natural causes and cycles that have some influence, but a large part of GW is a result of humans pulling CO2 out of the ground that was sequestered out of the system millions of years ago.  We burn it as fossil fuel.   The radiative forcing from the CO2 is very high although the gas is a minor component of the atmosphere.  Along with land conversions that may release CO2 and reduce the amount sequestered by plant, the proportion of CO2 has steadily increased, resulting in a measurable change in the climate.  Some people are misleading by indicating that it is a natural cycle or solar intensity is the major cause, but this is wrong.  If you upset  the carbon balance as burning gigatons per year of fossil fuel has over the past 100 years has, some adjustments in climate (as well as other system) are going to happen.  Lets hope the interactions among the systems result in favorable changes in climate and the other systems.  I think we should plan to reduce the chance of unfavorable changes.  Seems like simple logic to me, but some just don't see it that way

Answer 7

Can anyone explain this difference in ocean temperatures?

The differences don't seem to follow ocean currents - but appear more related to the "Pacific Ring of Fire"

A 6-8 degree centigrade difference on the same latitude is HUGE!!!!

Answer 8

Probably not.  The most likely cause is that the Sun's output constantly changes, and currently the output is diminishing.

""Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity," Abdusamatov told RIA Novosti in an interview.

"Instead of professed global warming, the Earth will be facing a slow decrease in temperatures in 2012-2015. The gradually falling amounts of solar energy, expected to reach their bottom level by 2040, will inevitably lead to a deep freeze around 2055-2060," he said, adding that this period of global freeze will last some 50 years, after which the temperatures will go up again.

Answer 9

Actually the core is hot from the original heat and due to radioactive decay of certain isotopes.  What you suggest makes sense, but as a geologist I learned that the earth actually has great insulation due to the distance.  The rock itself holds most of the inner heat.  There is a temperature gradient but it is not that significant.  The atmospheric temperature is a much bigger factor.  For example, the permafrost remains cold because of the average ambient temperatures.
