A new paper by Dr. Ross mcKitrick of the University of Guelph shows how there are now fewer weather stations being used than at any time since 1915. And unlike what the alarmists would have you believe those weather stations are STILL the primary source of temperature data being used. Not satelites (which BTW confirm the planet is not warming). But I'll let you read the whole report and make up your own minds!
