The thing is, if the planet were not 'just so' then we wouldnt be here to notice.

Does the Sun provide us with all the heat we need?

I didn't mention God, Junkyard, I'm just curious to know why things are the way they are. Like why are you so agressive?

Just having watched the prog on our wonderful Solar System I'm just amazed that everything in our world "just happens to be" and no real scientific explanation
Well, you must have watched a different programme to me. I thought he was trying to explain the workings of the solar system, and how it was formed, by using exampes of the same physics operating here on Earth on a smaller scale. I though he did so brilliantly, I understood every word of it, and I now have a far greater undersanding of where it all comes form than I did before

So in that case the heat from the Earth's core is crucial to sustaining life as we know it on our lovely planet.
It certainly is in Iceland. After their banks going bankrupt the last thing they need is someone turning off their geothermal energy supply.

Right, well there's this thing called anthropic reasoning, and it goes like this. Lots of things on earth are co-incidentally just perfect for life, but this isn't a co-incidence. Life could only evolve sufficiently to think about these things on a planet where everything was just-so.
Or, to put it another way - there could well be billions of other planets out there where conditions are not perfect for life, but no-one'd have evolved on them to start thinking about it.
So not a remarkable co-incidence at all, rather a pre-condition of this very discussion.
As for insolation, I seem to remember a figure of 1.5kw/m2 from uni. Maybe this was at the equator. If we say X is the amount at the equator, then the amount at a latitude L = X * cos(L).. If I could be bothered I could probably remember how to work it out using calculus, given the total output of the sun.
And I don't think that the earth's core has much to do with ambient temperatures on the surface other than providing us with a magnetic field (which is of course vital, keeping the atmosphere in place). I seem to remember reading that it gets pretty warm on the moon which has no hot core. Also space stations etc would get really really hot when the sun's on them - that's why they get covered in tin foil. So I'm guessing that heat from the core makes not much difference.

You want aggresiion/anger/fury you want Mr Whoppitt I am more insightful sarcasm
or not as the case may be.
FWIW I am not sure I was aggressive in my post over reaction with child example possibly but I also gave an explanation as to why it "just happens to be so" and always will appear thus.Like why are you denying your agenda or your true view of how the world was made?

if we don't need the planetry core then it should be sold off - think of how many paperclips and patio heaters you could make out of a million billion gazillion tonnes of molten iron! We could then use the centre for weightless sex romps as gravity cancels out there...
