Would temperature data determine if oil cools the earth?

Question

Past temperature data could resolve the question- does oil cool the earth? Oil could be insulating earths' surface from earths core heat. Temperature from regions where oil is removed should be rising quicker than areas where oil has not been removed. As oil is removed a correlating rise in temperature should exists in these regions.

Answer 1

It would not make much of difference because there are areas of the crust that is much more dense.  Oil is part of the Earth's surface as another layer.  Then mantel is Kilometers deep of the surface.  There will always be heat flux from the mantel and the core.  Volcanoes and divergence of the oceanic crust also influence heat flux.

Earth is Getting warmer because of the radiation from the sun getting to the surface and being trapped in by CO2 and other greenhouse like gases.
