Here we go again. You dismiss the story because it was publicized by Breitbart.
Was it written and sourced from Breitbart? No.
The original story came from Paul Homewood's blog.
Where did the information come from? NOAA.
If you dislike his article and the obvious conclusions in it, then explain away the sourced data that it was compiled from.
The best solution to this story would be a full explanation from NOAA. I won't be holding my breath in anticipation.
These wholesale changes cannot be explained away changes to individual stations. It may be that homogenisation procedures, infilling of missing data and urban heat islands have contributed.
Under the new nClimDiv system, introduced in 2014, NOAA’s methodology is extremely opaque. They don’t, to the best of my knowledge, publish the data and adjustments used.
In essence, we are asked to accept NOAA’s version without being able to check or verify it.
Whatever the reason for the adjustments, the climate record for New York State has been changed out of all recognition, and bears no resemblance to the actual official data.
