While NOAA’s fraudulent adjustment of the global temperature data has not reached the main stream press or they choose to ignore it, here are some examples that you can present should the subject come up at the water cooler, the coffee bar or down at the pub. This is best done by comparing the before and after data.
NOAA’s US Historical Climate Networks stations are used to create the US portion of Global Historical Climate Network. They are also used to create state-by-state temperature histories accessible on the NOAA website. A 2011 paper announced that NOAA would be transitioning to updated and improved CONUS software around the end of 2013. The program used until the upgrade was called Drd964x. The upgrade was launched from late 2013 into 2014 in two tranches. Late in 2013 came the new graphical interfaces, which are an improvement. Then about February 2014 came the new data output, which includes revised station selection, homogenization, and gridding. The new version is called nClimDiv.
Here are three states. First is Maine, with the before/after data both shown in the new graphical format.
Second is Michigan, showing the graphical difference from old to new software.
And finally, California.
In each state, zero or very slight warming was converted to pronounced warming.
These three examples clear demonstrate there is anthropogenic temperature change. Humans changed the data, lowering the historical data to show increasing warming when there was none of very little to a lot, which fits the warmers message.
This is the message that Governor Brown is using to rob every citizen in the state, collecting climate change slush funds that can be spent on his favorite projects, like his high-speed rail to nowhere.
