I beg to differ, but you did say "it does contribute to climate change". As a relative constant it does not contribute to climate change, but it does contribute to the overall temperature of the planet. It could only contribute to change if it were changing, similar to the way the CO2 level is changing, or the methane level is changing, or the solar influx is constantly changing.

And for the record, despite what Al Gore says, the temperature at the core of the Earth in not several million degrees. It's about 13,000 degrees F.
