I haven’t researched this particular issue, but it’s obvious to anyone with any critical thinking ability whatsoever that:
1) the NCEI had their reasons for making those adjustments
2) the reasons for those adjustments are based in actual science that they are qualified to do, otherwise NCEI wouldn’t have hired them
3) there is no hidden agenda in this particular issue
4) the earth is warming
and 5) humans are the primary cause of said warming.
It’s utterly ludicrous to disagree with any one of these points, let alone all 5.
