Play fair - just because global warming is BS doesn't mean all scientists are BS-ers.

Please! I didn't say "all". However, how can they not at least know the temp at which they supposedly melted a diamond? Or, at the very least give a close estimate?

As explained in the article, when you heat up diamond it doesn't go directly from solid diamond to liquid diamond, but physically changes into graphite first. Then the graphite melts (which, of course, only tells you the melting point for graphite, but not diamond).
