Re: 9/11 was an inside job, as well @Jack of Shadows
Would you know what to do with the raw data? Do you even know what "raw" means when it comes to data? It's not just unadjusted, but bereft of any attempts to remove anomalous readings that are clearly incorrect.
For example, my computer records the current air temp every 5 minutes from a sensor I have on the north side of my house. It even has a ventilation shroud over it to ensure it's measured as a shade temperature and it's 6' off the ground. However, for about 3 months every year, the early morning sun is able to reach the sensor and cause a rather substantial increase in temperature for about 30 to 40 minutes, at which time it can jump 10 to 15 degrees before falling back to the actual air temperature. Should I take that to mean that from May to August, my location experiences an unusual phenomenon that causes the local temperature to spike a hour of so after sunrise, or that I have bad sensor placement and need to throw those readings out until I've corrected the situation?
That's what raw data is. And if you think that it tells you anything besides you have a period of bad measurements, you're just fooling yourself. Science includes applying your brain; without that, we'd still be talking about that amazing experiment that demonstrated how neutrinos can travel through the Earth at a speed faster than light.
Weather stations move, they are subject to maintenance issues, human error, and other problems that can make for bad data. And even without all of that, weather stations are stationary, but the world around them is not. What once was a bucolic glen at the edge of town is now the middle of an airstrip, surrounded by tarmac, planes, and buildings. I think you'd be surprised how much worse global warming would look if each weather station was left unadjusted and tracked through the 100+ years as an urban heat island developed around it.
