Global cooling the catch-all scape goat. Check the temp records for the last 5 years. "Up" is the operative word.

Maybe we should look at the abundance of drilling rigs that have popped up in the recent months in our area. Just look at DFW Airport every other day it seemed a new rig was springing up. North Tx has gone gas crazy, with the Barnett, Everyone wants their cut so lets sell the mineral rights and make some bucks. Anyone think it might be the amount of drilling and the pressure changes that it is causing could be the reason. Global warming? Erosion? Right, just keep listening to the people behind the bucks, they will always steer you in the right direction. DUH!!!!!

Not anyone who has any knowledge of science, earthquakes, drilling, or reservoirs.

Quakes are not located anywhere near the drilling.

The drilling places a 6 inch hole laterally (usually) through a specific formation once every twenty to forty acres.

Gas is extracted that is in the tiny holes in the rock as well as gas that is adsorbed to the carbon bits in the rock. Any pressure difference causes fluid flow, not rock flow.
