What's your source on this? As someone who doesn't normally follow these kinds of reports, does NOAA have a history of falsifying data?
Further, what's your source on your last statement, that global temperatures are dropping?

The NOAA does adjust the data (and continues to do so) based on various factors like time of observation (TOBS), urban heat island effect (UHI). As well as infilling data when a station drops or they don't have the coverage.
As for the global temp dropping. That is most likely based on the satellite data showing a slight decrease (the hiatus).
