Weather phenomena is important to aviators, and weather stations tend to be clustered around airports. Lets examine just one photo, taken of a weather station at an airport.
With jet blast playing across your weather station every day, your average temperature measurements are utter bullshit. And this is just one example of thousands. Of course, the warmists will tell you that their data is "adjusted". I should say so, it's adjusted by jet blast. In other words, it's total bullshit. We don't know, because every-so-often, someone blows hot air across your station.
Other folks are noticing, and John Hinderaker, over at Powerline, has a good post with a lot more science than I feel like absorbing. John points out that some folks are starting to notice that the data has been tampered with:
One of the areas that Homewood has looked at is Paraguay. In a post titled All of Paraguay’s temperature record has been tampered with, he found that GISS has systematically altered temperature records to make the past look cooler and the present warmer, and to create an entirely fictitious warming trend.As they say, go read the whole thing, but I've known for years that the Glowball Warmening argument was total bullshit. Simply look at the photo above, and tell me that the data generated there is valid.
