Abstract

GEOCLASTICA LTD TECHNICAL NOTE 2021-5. Two simple slides (5-minute read). Be appalled. NB, AUGUST 2021: they've shifted it back again (see Slide 3).
Last month I showed how NASA overstated 1975-2020 warming ... https://www.researchgate.net/publication/353165819
Here’s another manipulation. In 2021 NASA lowered the 2016 global average temperature, previously the highest on record, to make
2020 seem the hottest. Below are copies of NASA’s 1880-2020 global temperature chart ‘before & after’ the subtle adjustment.

How’s this for disingenuity bordering on dishonesty? ... NASA statement 6 months ago, 14th Jan 2021 ...

‘the globally averaged temperature in 2020 ... was slightly warmer than 2016 ... “The last seven years have been the warmest ... on
record1, typifying the ongoing and dramatic warming trend,” said GISS Director Gavin Schmidt2 ... “... as the human impact on the
climate increases, we have to expect that records will continue to be broken.”‘ The article did not mention the altered 2016 data-
point; or the 2016 highest monthly temperature on record (red circle above). In fact overall cooling since Feb 2016 (blue arrow)
continues today. 1 i.e. since 1880 2 see his 2013 awkward non-discussion ... https://www.youtube.com/watch?v=V96k4BO2sBw
Which newspaper was among the first to trumpet NASA’s announcement, on the same day, 14th Jan 2021? Yes, left-wing ultra-
alarmist The Guardian ... “2020 was hottest year on record by narrow margin, Nasa says” ...

Feeling misled? Our star, the Sun, drives global warming (alternating with cooling; black bars in Slide 1); not CO2.
