Hotter Earth Cooks Up More Thunderstorms

If you follow climate science at all, you’ve probably heard that a warming world is likely to generate more nasty weather and a lot more weather extremes, kind of like the extreme droughts and then torrential flooding that Colorado, New Mexico and other western states have experienced.

Boom! Super Seismo-Sonic Earthquakes Are Real

The inner workings of bizarre and potentially dangerous earthquakes that break the seismic sound barrier have now for the first time been confirmed in laboratory experiments with real rocks, report scientists in today’s issue of the journal Science.

"Super Seismo-Sonic" — isn’t that a wrestler’s name?
