Here is a must read from Steven Goddard’s Real Science blog – http://stevengoddard.wordpress.com/2014/01/19/just-hit-the-noaa-motherlode/
I spent the evening comparing USHCN V1 and V2 graphs, and discovered a huge discrepancy between their V1 and V2 adjustments.
But when they switched to V2, they started adjusting older temperatures downwards, and left post-2000 temperatures more or less intact. This created a huge jump (greater than one degree) downwards for all years prior to 2000.
They created a significant warming by reversing polarity of the adjustment in the pre-2000 years.
Bottom line is that there is clearly a huge error in the USHCN adjustments which has added a non-existent one degree hockey stick warming to the official US temperature record, and I now know just where to look for it in their code.
NOAA made a big deal about 2012 blowing away all temperature records, but the temperature they reported is the result of a huge error. This affects all NOAA and NASA US temperature graphs, and is part of the cause of this famous shift.
I highly recommend you go to the link and review the multitude of graphs and decide for yourself. Global warming has never been anything more than crony-capitalism with tremendous profits at stake. Clear thinking people have accepted climate change as a normal course of events as well as the fact that humans do indeed have an impact on it. However, it’s negligible in the big picture. That won’t stop the stakeholders from pushing it endlessly as there is simply too much money to be made.
Please do your part to spread the truth.
