What hoax?
Okay, how about this. If there is such a hoax, it involves a LOT of people. Let's imagine a typical member. Let's say he's got a Masters in physics and has specialized in atmosperic physics and meteorology. He works for NOAA or NASA or Hadley or Berkeley Earth. His a mid level tech guy who is involved in the process of collecting, processing and analyzing climate data: temperature, wind speed, pressure, etc, acquired from gjround stations, balloons, aircraft and satellites. He's a crucial cog in the hoax because he's the one that has to change the numbers. It's not easy for himi to figure out how to do that without his data sticking out like a sore thumb from hes neighbor's data. It requires close coordination around the globe with dozens if not hundreds of people in jobs just like his and constantly. That data get collected and processed around the clock. It's a lot of work. And, of course, if he gets caught he'll lose his job and might just go to jail.
My question is WHY? What does our typical cog in the machines here do what he would have to do? It's not going to make HIM rich. It's not going to make HIM powerful. He's just a regular Joe. He doesn't want to end civilization or push us all back to living in bark huts and drinking rainwater. WHY would he involve himself with the hoax you all claim exists?
