"...no matter what the temperature of the outer core is, and most likely it is quite high, the mantle is cold, and its rigidity increases with depth, because otherwise seismic wave velocity cannot increase with depth, for example for P waves from 6-7 km/sec in the surface layers to about 14 km/sec at the mantle-core boundary." -- Stavros T. Tassos, seismologist, October 2008
Via Watts Up With That: Gore has no clue – a few million degrees here and there and pretty soon we’re talking about real temperature.
Temperature of the sun’s corona: 1–2 million kelvin
Temperature of the sun’s photosphere: 6,000 kelvin
Temperature of the Earths mantle, more than “2 kilometers or so down”: between 500 °C to 900 °C (773 to 1173 kelvin)
Watching Gore make a complete scientific idiot of himself on national TV: priceless
