There have been so many instances of errors data manipulation, and other shenanigans, from global warming alarmists that the rest of us can barely keep up with them; today’s example ups the number of my posts on this to thirty-two. Still, every one needs proper exposure, lest the breadth and depth of this be hidden.
So, today, Willis Eschenbach (WUWT) discovers the IPCC’s claims of warming in Nepal, goes deep into the NASA-GISS data wickets, and finds (emphasis added) . . .
GISS has made a straight-line adjustment of 1.1°C in twenty years, or 5.5°C per century. They have changed a cooling trend to a strong warming trend.
In other words, NASA-GISS literally hid the decline in Nepal’s temperatures.
Eschenbach naturally wonders what else is wrong with the NASA-GISS data.
Once again we see huge adjustments made to individual temperature records without reason or justification. This means simply that until GISS are able to demonstrate a sound scientific foundation for their capricious and arbitrary adjustments, we cannot trust the final GISS dataset. Their algorithm obviously has significant problems that lead to the type of wildly unreasonable results seen above and in other temperature datasets, and they are not catching them. Pending a complete examination, we cannot know what other errors the GISS dataset might contain.
Lest anyone forget, this is the same GISS that got caught “smoothing” data in the North Pole.
