Time to come up with a new one...
The Core of the Earth is Going to Destroy Life as We Know It.
That won't work unless it simultaneously becomes the excuse for mass socialization / communist expropriation, and the destruction of Western Civilization.
Let's try again:
"The Reversal of Magnetic Poles is being caused by Big Mining Companies extracting too much iron. The only way to stop the Total Destruction of the Earth is by collecting all the iron ever mined by rich countries and injecting it back into the core of the Earth. The U.N. must act now and confiscate every major household appliance to avoid catastrophe."
Will any of my carbon credits help me survive this coming disaster.
