NASA Hiding The Decline

In 1974, NCAR and CRU reported half a degree global cooling since the early 1940’s, and blamed drought and famine on it.

NCAR data showed Northern Hemisphere cooling from 1870 to 1880, followed by 0.7C global warming from 1880 to 1940, and global cooling of 0.6C from 1940 to 1970. There was no net warming from 1870 to 1970, and possibly cooling during that period.

Briffa’s trees showed the same 1940’s to 1970’s cooling, which Michael Mann hid.

Reality didn’t fit the global warming narrative, and in order to facilitate Michael Mann’s farcical hockey stick – NASA did their own nature trick and erased the post-1940 cooling from the surface temperature record.

The next graph overlays the current NASA graph on the 1974 NCAR graph at the same scale. It shows how NASA has hidden the post-1940 decline, just as Michael Mann did with the tree ring data. NASA’s nature trick.

Make no mistake about it, global warming is the biggest scientific fraud in history.
