Seriously. Via Watts Up With That?:
No second chance? Can Earth explode as a result of Global Warming? Dr Tom J. Chalko 1 , MSc, PhD Submitted on 8 April 2001, revised 30 October 2004. Published in NU Journal of Discovery ISSN 1444 1454 Publisher: Natural University
Abstract: The heat generated inside our planet is predominantly of radionic (nuclear) origin. Hence, Earth in its entirety can be considered a slow nuclear reactor with its solid ”inner core” providing a major contribution to the total energy output. Since radionic heat is generated in the entire volume and cooling can only occur at the surface, the highest temperature inside Earth occurs at the center of the inner core. Overheating the center of the inner core reactor due to the so-called greenhouse effect on the surface of Earth may cause a meltdown condition, an enrichment of nuclear fuel and a gigantic atomic explosion.

Curious, of course, I did a brief Google search of Dr. Chalko. If this is the same guy (a good bet, I'd say), here's a brief bio:
He plays classical guitar exceptionally well, enjoys windsurfing (he calls himself a speed addict here), takes time to practice meditation, telepathy and astral travel. His hobbies include challenging paradigms and paradoxes in geophysics, studying puzzling properties of electro-photonic glow (Auras) using Kirlian camera, learning to see human aura, discovering purpose of life, as well as organizing controversial seminars.
UPDATE: Oh. My. God. This is so much better: A CNN dope actually asked the following: “Talk about something else that’s falling from the sky and that is an asteroid. What’s coming our way? Is this an effect of, perhaps, of global warming or is this just some meteoric occasion?”
